let me talk about SpaceX and rockets for a second

because while I don't give a flying fuck about musk

yesterday's (20/04/2023) launch was a succes. The point was to get it in the air, anything more was extra. It was a test flight. Every rocket goes through this process.

SpaceX is not bad at making rockets, there are a lot of very skilled scientists involved and rockets are constantly being reused etc. technology has been rapidly improving this field.

This is new technology and it is being tested. As I have said before, this happens and has happened for every rocket. With NASA, with Rocketlab with SpaceX, any company you can think of.

The scientists now have a lot of data they can use to improve the rocket where things went wrong.

This was a test flight, nothing was on board, this is a testing phase and this is new development. This was the first time that the full stack was tested in flight. I am speaking for the scientists here because they are the actual key to this. They've (scientists in this field in general) made some incredible forward steps in the last years.

It's probable that the explosion was planned to some extent and likely that it was absolutely expected to happen.

Yes you can laugh at the explosion, yes it looks hilarious I can appreciate the memes a lot please continue.

But do realise that this did not go wrong and this is a positive for the scientists that work on it.

#spacex #science #rockets #space #starship #scientists #because no one seems to get it #this is a rocket in testing phase #and i am not praising musk #i hate the man

🦜 - Why did the parrot learn to video call? Because he wanted to see his tweetheart!

The Best News of Last Week - May 2, 2023

1. Engineers develop water filtration system that permanently removes 'forever chemicals'

Engineers at the University of British Columbia have developed a filtration system that would permanently remove "forever chemicals" from drinking water. This news comes after a recent study revealed nearly 200 million Americans have been exposed to PFAS in their tap water. Dr. Madjid Mohseni, a professor at British Columbia, shares his research.

2. Berkeley diner provides free meals to anyone who's hungry, no questions asked

The Homemade Cafe in Berkeley, California, is giving away free breakfasts to anyone who is hungry, no questions asked. Owner Collin Doran's Everybody Eats Program started when he saw people panhandling outside his diner. Customers can add $5 to their bill to help the program or grab a coupon for a free meal. Doran's act of kindness has resulted in a 15% increase in business, and he hopes that more businesses will follow his lead in making the world a better place.

3. Pope Francis gives women right to vote in bishops’ meeting for first time

Pope Francis has decided to give women the right to vote at an upcoming meeting of bishops, an unprecedented change that reflects his hopes to give women greater decision-making responsibilities.

Francis approved changes to the norms governing the Synod of Bishops, a Vatican body that gathers the world’s bishops together for periodic meetings, following decades of demands by women to have the right to vote.

4. US adult cigarette smoking rate hits new all-time low

U.S. cigarette smoking dropped to another all-time low last year, with 1 in 9 adults saying they were current smokers, according to government survey data released Thursday. Cigarette smoking is a risk factor for lung cancer, heart disease and stroke, and it’s long been considered the leading cause of preventable death. In the mid-1960s, 42% of U.S. adults were smokers. The rate has been gradually dropping for decades, due to cigarette taxes, tobacco product price hikes, smoking bans and changes in the social acceptability of lighting up in public.

Last year, the percentage of adult smokers dropped to about 11%, down from about 12.5% in 2020 and 2021.

5. Scientists taught pet parrots to video call each other - and the birds loved it

When humans are feeling lonely, we can call or video chat with friends and family who live far away. The idea for this study was not random: In the wild, parrots tend to live in large flocks. But when kept in captivity, such as in people’s homes as pets, these social birds are often on their own. Feeling bored and isolated, they may develop psychological issues and can even resort to self-harming tendencies like plucking out their feathers. New research suggests that these chatty creatures may also benefit from virtually connecting with their peers.

Domesticated parrots that learned to initiate video chats with other pet parrots had a variety of positive experiences, such as learning new skills. The parrots that learned to initiate video chats with other pet parrots had a variety of positive experiences, such as learning new skills including flying, foraging and how to make new sounds. Some parrots showed their toys to each other.

I wanted to see this experiment so bad, so here’s a video from the paywalled study. I uploaded it on my youtube channel.

6. World’s First Carbon Import Tax Approved by EU Lawmakers

The European Union’s parliament approved legislation to tax imports based on the greenhouse gases emitted to make them, clearing the final hurdle before the plan becomes law and enshrines climate regulation in the rules of global trade for the first time.

Tuesday’s vote caps nearly two years of negotiations on the import tax, which aims to push economies around the world to put a price on carbon-dioxide emissions while shielding the EU’s manufacturers from countries that aren’t regulating emissions as strictly, or at all. The tax gives credit to countries that put a price on carbon, allowing importers of goods from those countries to deduct payments made for overseas emissions from the amount owed at the EU’s borders.

7. Genetic Driver of Anxiety Discovered

An international team of scientists has identified a gene in the brain responsible for anxiety symptoms and found that modifying the gene can reduce anxiety levels, offering a novel drug target for anxiety disorders. The discovery highlights a new pathway that regulates the brain’s response to stress and provides a potential therapeutic approach for anxiety disorders.

Critically, modification of the gene is shown to reduce anxiety levels, offering an exciting novel drug target for anxiety disorders.

That's a driver I'd like to uninstall.

Eclipses create atmospheric gravity waves, student teams confirm

Student teams from three U.S. universities became the first to measure what scientists have long predicted: eclipses can generate ripples in Earth's atmosphere called atmospheric gravity waves. The waves' telltale signature emerged in data captured during the North American annular solar eclipse on Oct. 14, 2023, as part of the Nationwide Eclipse Ballooning Project (NEBP) sponsored by NASA.

Through NEBP, high school and university student teams were stationed along the eclipse path through multiple U.S. states, where they released weather balloons carrying instrument packages designed to conduct engineering studies or atmospheric science experiments. A cluster of science teams located in New Mexico collected the data definitively linking the eclipse to the formation of atmospheric gravity waves, a finding that could lead to improved weather forecasting.

"Understanding how the atmosphere reacts in the special case of eclipses helps us better understand the atmosphere, which in turn helps us make more accurate weather predictions and, ultimately, better understand climate change."

Catching waves in New Mexico

Previous ballooning teams also had hunted atmospheric gravity waves during earlier eclipses, research that was supported by NASA and the National Science Foundation. In 2019, an NEBP team stationed in Chile collected promising data, but hourly balloon releases didn't provide quite enough detail. Attempts to repeat the experiment in 2020 were foiled by COVID-19 travel restrictions in Argentina and a heavy rainstorm that impeded data collection in Chile.

Project leaders factored in these lessons learned when planning for 2023, scheduling balloon releases every 15 minutes and carefully weighing locations with the best potential for success.

"New Mexico looked especially promising," said Jie Gong, a researcher in the NASA Climate and Radiation Lab at the agency's Goddard Space Flight Center in Greenbelt, Maryland, and co-investigator of the research on atmospheric gravity waves. "The majority of atmospheric gravity sources are convection, weather systems, and mountains. We wanted to eliminate all those possible sources."

The project created a New Mexico "supersite" in the town of Moriarty where four atmospheric science teams were clustered: two from Plymouth State University in Plymouth, New Hampshire, and one each from the State University of New York (SUNY) Albany and SUNY Oswego.

Students began launching balloons at 10 a.m. the day before the eclipse.

"They worked in shifts through the day and night, and then everyone was on site for the eclipse," said Eric Kelsey, research associate professor at Plymouth State and the NEBP northeast regional lead.

Each balloon released by the science teams carried a radiosonde, an instrument package that measured temperature, location, humidity, wind direction, and wind speed during every second of its climb through the atmosphere. Radiosondes transmitted this stream of raw data to the team on the ground. Students uploaded the data to a shared server, where Gong and two graduate students spent months processing and analyzing it.

Confirmation that the eclipse had generated atmospheric gravity waves in the skies above New Mexico came in spring 2024.

"We put all the data together according to time, and when we plotted that time series, I could already see the stripes in the signal," Gong said. "I bombarded everybody's email. We were quite excited."

For students, learning curves bring opportunity

The program offered many students their first experience in collecting data. But the benefits go beyond technical and scientific skill.

"The students learned a ton through practicing launching weather balloons," Kelsey said. "It was a huge learning curve. They had to work together to figure out all the logistics and troubleshoot. It's good practice of teamwork skills."

"All of this is technically complicated," Des Jardins said. "While the focus now is on the science result, the most important part is that it was students who made this happen."

United Kingdom wants to accelerate the development of the future Tempest fighter

UK scientists, engineers and innovators collaborate to accelerate the future air power capacity of combat aircraft

Fernando Valduga By Fernando Valduga 01/12/2023 - 11:00am in Military

The UK's leading combat airlines and the Ministry of Defense conducted research with leading scientists in machine learning, artificial intelligence, data science and computing to support software development for a next-generation jet fighter.

Tempest will be part of the UK's future combat air system (FCAS) and was designed to be a supersonic poaching equipped with pioneering technologies, including integrated state-of-the-art detection and protection capabilities. These capabilities will be provided, in part, by millions of lines of code in aircraft, with many more lines of code also present in ground systems. This means that Tempest's software needs to be more robust and resilient than that of its potential opponents.

The collaboration provided valuable information about the software requirements, design, delivery, operation, speed of updates and maintenance for both the fighter and the training systems that pilots and maintainers will use to operate and support the aircraft.

Outsmart Insight, a deep technology intelligence company, and Oxford Creativity, a group that offers a systematic approach to innovation and creative problem solving, have conducted targeted research with scientists, engineers and academics. The research addressed the most challenging problems faced by software development over the several decades of expected life of the program: flexible ways to manage computational resources; the role of reliable artificial intelligence; software reuse; and increasing software reliability.

Air Commodore Martin Lowe, Director of the FCAS Program for the UK Ministry of Defense, said: “Software is critical to Tempest because the future operating environment requires adaptability, including frequent software updates. But the software also poses a great risk of delivery. Recent history shows the dangers that arise when software is poorly done and the advantages of doing it well. The advantages are so significant that, in terms of operational capacity, the people who provide the software are as important as the people who maintain the aircraft or the pilots who fly them.

"It's great to see the enthusiasm and optimism that Outsmart Insight and Oxford Creativity brought to this study. This gives us greater confidence that we can take advantage of the opportunities offered by software-based advances in the program. This project also showed the value of collaborating in research with important organizations and individuals, both in academia and in industry."

Based on the findings, Team Tempest partners commissioned follow-up research aimed at the UK academy, which aims to support more robust software development, which can be hosted in a more resilient way. This work supports the program's vision for a modern, efficient, safe and constantly improving software delivery ecosystem.

Tempest should be in service by 2035. The program will provide significant economic benefits to the UK, helping to sustain and develop critical skills and ensure that the technical and industrial knowledge of hundreds of organizations across the UK remains at the forefront of advanced air combat systems for future generations.

He has work published in specialized aviation magazines in Brazil and abroad. Uses Canon equipment during his photographic work in the world of aviation.

Recent document from 2023:

In 2023, during the reworking of data and testimony, a puzzling document emerged from the hiding place of NASA's archives. It is a letter from Captain Thomas Mitchell, one of the astronauts who participated in the mission. In the letter, addressed to one of his colleagues, Mitchell reveals that the Mars Pioneers' mission was a success. He describes the difficulties of growing certain grains and feeding themselves adequately, the amazing landscapes and the construction of the first basic structures on the surface of Mars.

Current testimonies:

In recent years, some members of the original mission crew have emerged from anonymity to share their experiences. Lisa Turner, one of the children who left for Mars in 1972, has written a book entitled 'Secrets of Mars: My Life on the Red City', revealing details of daily life in the Martian colony. Turner describes how the colonists faced unique challenges, such as managing limited resources, creating a habitable artificial atmosphere and adapting to a completely different environment. His accounts were supported by interviews with crew members and photos and audio recordings recovered from the mission.

In addition, former NASA engineer John Anderson recently provided further details on the Mars Pioneers mission. Anderson shared that the mission was originally conceived as an experiment to assess humanity's ability to survive on other planets. He revealed that the Martian colony continued to exist for several years, with periodic supplies and support arriving from Earth.

NASA declined to officially comment on these testimonies, stating that all information regarding the colonisation of Mars remains highly confidential. However, these recently surfaced testimonies and documents have stirred the public imagination and fuelled speculation about the future of human colonisation of Mars.

The secret mission of the Mars Pioneers in 1972, although never officially confirmed by NASA, remains a fascinating chapter in space history. Uncovered documents and accounts from the 1970s and present day provide an insight.

DID POLYNESIAN VOYAGERS REACH THE AMERICAS BEFORE COLUMBUS?

History.com - May 25, 2023 According to science, voyagers from Moananuiākea reached America around 800 years ago. “A 2020 study found that Polynesians from multiple islands carry a small amount of DNA from indigenous South Americans, and that the moment of contact likely came some 800 years ago…” Polynesian voyagers sailed without a compass or any other nautical instruments. Yet by reading the stars, waves, currents, clouds, seaweed clumps and seabird flights, they managed to cross vast swaths of the Pacific Ocean and settle hundreds of islands, from Hawaii in the north to Easter Island in the southeast to New Zealand in the southwest. Evidence has mounted that they likewise reached mainland South America—and possibly North America as well—long before Christopher Columbus. “It’s one of the most remarkable colonization events of any time in history,” says Jennifer Kahn, an archeologist at the College of William & Mary, who specializes in Polynesia. “We’re talking about incredibly skilled navigators [discovering] some of the most remote places in the world.” Tracing Polynesian Ancestry Based on linguistic, genetic and archeological data, scientists believe that the ancestors of the Polynesians originated in Taiwan (and perhaps the nearby south China coast). From there, they purportedly traveled south into the Philippines and further on to New Guinea and the Bismarck Archipelago, where they mixed with the local populace. By around 1300 B.C., a new culture had developed, the Lapita, known in part for their distinct pottery. These direct descendants of the Polynesians rapidly swept eastward, first to the Solomon Islands and then to uninhabited Vanuatu, New Caledonia, Fiji, and elsewhere. “The Lapita were the first ones to get into remote Oceania,” says Patrick V. Kirch, an anthropology professor at the University of Hawaii at Mānoa, and author of On the Road of the Winds: An Archeological History of the Pacific Islands before European Contact. “It was really a blank slate as far as humans were concerned.” By the 9th century B.C., the Lapita had made it as far as Tonga and Samoa. But then a long pause ensued without further expansion. Researchers note that, beyond Tonga and Samoa, island chains are much further apart, separated in some cases by thousands of miles of open ocean, and that the winds and currents generally conspire against sailing east. Perhaps Lapita boats simply weren’t up to the task. Moreover, as Kirch points out, the closest coral atolls had not yet stabilized by that time. “It’s possible that there was some voyaging past Samoa,” he says, “but they would have found just coral reefs and not actual land they could settle.” Double-Hulled Canoes Accelerate Expansion During the long pause, a distinct Polynesian culture evolved on Tonga and Samoa, and voyagers there gradually honed their craft. In time, they invented double-hulled canoes, essentially early catamarans, lashing them together with coconut fiber rope and weaving sails from the leaves of pandanus trees. These vessels, up to roughly 60-feet long, could carry a couple dozen settlers each, along with their livestock—namely pigs, dogs and chickens—and crops for planting. “They now had the technological ability and the navigational ability to really get out there,” Kirch says. Though the exact timeline has long been disputed, it appears the great wave of Polynesian expansion began around A.D. 900 or 950. Voyagers, also called wayfinders, quickly discovered the Cook Islands, Society Islands (including Tahiti), and Marquesas Islands, and not long after arrived in the Hawaiian Islands. By 1250 or so, when they reached New Zealand, they had explored at least 10 million square miles of the Pacific Ocean and located over 1,000 islands. “You can fit all of the continents into the Pacific Ocean,” Kahn explains. “It’s a huge, huge space to traverse.” Even the tiniest and most remote islands, such as Pitcairn, did not escape their notice. As Kirch points out, no one else in the world was remotely capable of such a feat at that time. “Around 1000 A.D., what were Europeans doing?” Kirch says. “Not much in the way of sailing.” He adds that, as late as the 15th century, even the most accomplished European seamen, like Vasco da Gama, were merely hugging the coast. Easter Island Among Many Inhabited by Polynesian Voyagers The Polynesians did not have a system of writing to record their accomplishments. But they did pass down stories orally, which tell, for example, of how Hawaiian settlers came from Tahiti, more than 2,500 miles away. “Where the sun rises, in Hawaiian understanding anyway, is a place where the gods reside and our ancestors,” says Marques Hanalei Marzan, cultural advisor at the Bishop Museum in Honolulu. “To get to that place is probably one of the reasons why the migration east continued.” (As an April 2023 study confirms, Polynesian voyagers sometimes sailed west as well into what’s commonly referred to as the Polynesian Outliers.) Each island chain developed its own unique characteristics. On Easter Island, for instance, the inhabitants constructed giant stone statues. Yet all Polynesians spoke related languages, worshipped a similar pantheon of gods, and built ritual sites with shared features, Kahn explains. The various islands also maintained at least some ties with each other, particularly during the heyday of Polynesian expansion. “It’s not just that they came from a place and left and never made their way back,” Marzan says. “They actually continued those relationships.” Evidence that Polynesian Sailors Reached Americas Most experts now believe the Polynesians crossed the entire Pacific to mainland South America, with Marzan saying it happened “without question.” Stanford University biologist Peter Vitousek has similarly told HISTORY that “we’re absolutely sure,” putting the odds of a South American landfall in the 99.9999 [percent] range.” For one thing, experts note that Easter Island (also known as Rapa Nui) lies only about 2,200 miles off the South American coast, and that Polynesian voyagers, capable of locating a speck of rock in the vast Pacific, could hardly have missed a giant continent. “Why would they have stopped?” Kahn says. “They would have kept going until they couldn’t find any more.” Genetic evidence backs up this assertion. A 2020 study found that Polynesians from multiple islands carry a small amount of DNA from indigenous South Americans, and that the moment of contact likely came some 800 years ago (not long after the Vikings, the best European sailors of their era, made landfall on the Atlantic coast of the Americas). Archeologists have likewise found the remains of bottle gourds and sweet potatoes, both South American plants, at pre-Columbian Polynesian sites. Some scientists speculate that the sweet potato could have dispersed naturally across the Pacific, but most agree that the Polynesians must have brought it back with them. “Try to take a sweet potato tuber and float it,” Kirch says. “I guarantee it won’t float very long. It will sink to the bottom of the ocean.” Poultry bones from Chile appear to show that Polynesians introduced chickens to South America prior to the arrival of Columbus, though some scientists have disputed these findings. Meanwhile, other researchers analyzing skulls on a Chilean island found them to be “very Polynesian in shape and form.” Less evidence ties the Polynesians to North America. Even so, some experts believe they landed there as well, pointing out, among other things, that the sewn-plank canoes used by the Chumash tribe of southern California resembled Polynesian vessels. What Happened to Polynesians in Americas? No Polynesian settlement has ever been unearthed in the Americas. It therefore remains unclear what happened upon arrival, particularly since, unlike the Pacific islands, these landmasses were already populated. Perhaps, Kahn says, “they got up and left and went back.” When Captain James Cook explored the Pacific in the late 1760s and 1770s, thus ushering in a wave of Western imperialism, he recognized the Polynesians’ exemplary sailing skills. “It is extraordinary that the same nation should have spread themselves over all the isles in this vast ocean, from New Zealand to [Easter Island], which is almost a fourth part of the circumference of the globe,” he wrote. Eventually, however, as they colonized the islands and suppressed native languages and cultures, Western powers began to downplay Polynesian achievements, according to Marzan, who says they assumed “that the people of the Pacific were less than.” Some falsely claimed, for instance, that Polynesian sailors had merely drifted along with the winds and currents. (It didn’t help that, at the time of European contact, many Pacific Islanders no longer used large, oceangoing canoes. Some, like those on Easter Island, had already chopped down all the tall trees needed to produce them.) Worst of all, European diseases decimated the Polynesian population. “It was this massive, devastating loss,” Kirch says. “And when you have that, your society really falls apart.” Before long, most remaining Polynesians began sailing with Western techniques. More recently, though, the old traditions have been revived, starting around 1976, when the Polynesian Voyaging Society sailed, without instruments, from Hawaii to Tahiti. They have since embarked on numerous other expeditions, including a worldwide voyage from 2013 to 2017. “The Polynesian Voyaging Society has really inspired many cultures across the Pacific to reconnect with their traditional practices,” Marzan says. Once again, double-hulled canoes are plying the ocean.

By holding their breath, scalloped hammerhead sharks may be able to regulate their body temperature when diving thousands of feet below surface waters. Photograph By Greg Lecoeur

Do Sharks Hold Their Breath Underwater? This Species Might.

The “completely unexpected” behavior reported in scalloped hammerhead sharks raises questions about how widespread it may be among other species.

— By Dina Fine Maron | May 11, 2023

Scalloped hammerhead sharks may be holding their breath when they dive deep into frigid waters. The revelation, published today in Science, suggests that this strategy may allow the warm-water dwellers to regulate their temperature while they hunt.

This technique is “completely unexpected,” says Mark Royer, a shark biologist at the University of Hawaii who led the research. “This kind of behavior has never been observed in any kind of deep-diving fish,” he says, and it now raises questions about how widespread breath-holding may be among other species.

These critically endangered hammerhead sharks typically rely on forward movement to force water across their gills, which enables them to extract needed oxygen to breathe. Yet when the predators swim half a mile down to catch squid and other prey, the colder water could impact their metabolism, cardiac function, and eyesight—all factors that would reduce their hunting prowess.

By closing their gills and mouths—holding their breath—the animals could limit their exposure to cold water.

Some species, like bluefin tuna and mako sharks, have specialized anatomy that allows them to conserve their body heat in cold waters, but scalloped hammerheads don’t have that advantage.

That’s why some scientists have theorized that scalloped hammerheads maintain their body heat using simple thermal inertia—essentially relying on their large body size to help maintain their temperature and carry heat down as they dive into cold depths.

“Imagine you are trying to defrost your 15-pound Thanksgiving turkey: you bring it out of your freezer, and it takes a long time to thaw—that’s like thermal inertia,” says Marianne Porter, a biologist who studies shark movement at Florida Atlantic University and wasn’t involved in the study.

Yet tiny sensors that the team placed on adult scalloped hammerhead sharks—basically a “Fitbit for sharks” as Royer says—suggest that thermal inertia isn’t the reason they remain warm during their hunting trips at depth.

Hunting in Frigid Waters

For the study, the team analyzed detailed information about the swimming behavior, depth, and location of a small group of six tagged male sharks that collectively completed more than a hundred dives around Hawaii over several weeks.

Tiny probes also recorded the animals’ muscle temperatures during these repeated nighttime dives. That data, alongside further modeling, indicated that the sharks managed to largely maintain their body temperatures both when they were at surface waters around 80 degrees and when they plunged to more than 2,500 feet below where temperatures dropped by roughly half, to around 41 degrees.

Surprisingly the animals’ body temperatures did eventually drop when they had ascended and reached slightly warmer waters about halfway back to the surface—apparently when the sharks had opened their gills to obtain needed oxygen. That’s not what you would expect with thermal inertia, since there’d be a more constant warming and cooling to reach equilibrium, Royer says.

Though they didn’t observe the sharks actually closing their gills, his team suspects that’s what’s happening. To fully confirm their breath-holding hypothesis, Royer says, they will next need to affix cameras to the pectoral fins of these hammerheads to observe the gills opening and closing as sharks dive.

It’s still unclear how the 12-foot-long species may have acquired this breath-holding skill. “It’s possible they learn it from social interactions from other hammerheads that are diving,” says Royer, adding “another possibility is they’re following the example of other animals that dive and eat prey at the same depth.”

Compelling Evidence

Further backing the team’s breath-holding conclusion: prior footage from a remotely operated vehicle that shows an adult scalloped hammerhead shark swimming in Tanzania at more than 3,000 feet below the surface with its gills closed, and footage of the species in its typical surface waters with open gill slits. What’s more, another experiment from Royer’s team with deceased hammerheads in warm and cold water baths also supported their results.

“It’s a compelling paper—the way they have all these lines of evidence suggesting this might be happening,” says Porter. “I’m convinced” there’s breath-holding, she says.

Female scalloped hammerhead sharks also conduct deep dives, she says, so though this study only included males she suspects this applies to non-pregnant females as well.

The implications of this breath-holding work are “remarkable,” write the University of Western Australia’s Mark Meekan and Murdoch University’s Adrian Gleiss in an accompanying scientific commentary also published in Science.

If these rapidly declining species can pause respiration while foraging at depth they may cope with the increasingly common low-oxygen environments in our changing world better than expected, they write. Already, scalloped hammerheads occupy low-oxygen waters in the Gulf of California, and this newly discovered breath-holding skill may explain their presence, they note.

It's true that these animals may survive in low-oxygen areas for short periods, Porter says, but that’s likely not sustainable long-term. “I would wonder what happens if that becomes their reality all the time.”

Baby Brains

The human body carries on developing after birth – but the rate of these changes is still in question for developmental biologists. Here scientists take magnetic resonance imaging (MRI) scans of sleeping children’s cerebellums over the first two years of life, showing months 1–5 (top row) and regular intervals afterwards (bottom) from three different angles. While the young brain is constantly growing, it’s growing at a faster rate (warmer colours) during the first six months. The researchers investigated further, analysing the scans from 235 healthy children and looking at how 27 individual regions of their cerebellums change – finding, for example, that changes in specific ‘lobules’ corresponded with milestones in fine motor skills. This data could be used to pinpoint developmental windows for further study, or even to diagnose health issues or injuries during a toddler’s early life.

The woman responsible for the moon landing

#10 in Physics and Astronomy, 11/11/2023

Pictured is Margaret Hamilton, posing next to the code that she and her team wrote to guide Apollo 11 to the moon! As the lead computer scientist on the Apollo program, her skills saved the otherwise doomed mission not long before it was destined to end.

Enthusiastic about maths from a tender age, Margaret became an expert in writing software following her time at university. Later on, she took a job at MIT, learning to write software that could predict the weather.

In the mid-1960s, MIT announced they were looking for programmers to send men to the moon. Immediately, she knew this was for her, casting aside her original plan to attend graduate school for a degree in abstract maths to pursue the space program. Shortly, she became the first programmer hired for this project.

One amusing story about her time working on this is the time she took her daughter into the lab. As a working mother, it was necessary. One day, her daughter pushed a button, causing the system to crash. She quickly realised the astronauts could make this mistake, too, so she recommended adjusting the software. This was cast aside with a callous response: “Astronauts are trained never to make a mistake.”

On the 20th of July 1969, three minutes before the planned landing, data from a radar system overwhelmed the computer; this had accidentally been triggered by the crew. This was the exact mistake Hamilton’s daughter had made. Within hours, this was corrected, however, if it wasn’t for Hamilton’s skilful programming, the computer would not have recognised that error in the first place.

In 2016, the 80-year-old Margaret received the President Medal of Freedom by Barack Obama. During the presentation, he stated, “Our astronauts didn’t have much time, but thankfully they had Margaret Hamilton.”

You may have wondered where the term ‘software engineering’ came from. Being a young, curious student, I wondered what drew the line between simple, creative hobbies, and real-time problem-solving. Margaret Hamilton, it appears, is one of the people who helped paint this distinction.

She called her work “software engineering.” And for this, she was criticised. However, retrospectively, no one laughs anymore. The importance of programming, more specifically her work, is recognised properly now.

Live action Eggman and Bowser (2023) interaction head canons

The likelihood of Paramount and Illumination working together on a film is low - however here are some scattered ideas for them. It would be interesting if their crossover is similar to the movie Roger Rabbit.

Firstly, when Bowser and Eggman team up against their heroes they learn to get over some biases towards each other. For example Eggman thought Bowser was just a violent beast but he actually had shown to be clever. Bowser would had at first glance view Eggman as some mustached nerd that just works with robots but the scientist had shown knowledgeable leadership over others with an iron fist which is something to take note of.

Eggman would also offer some goat latte to Bowser from the Mean Bean Coffee Cafe. The dragon turtle would rather have tea but check before drinking in case it’s poisoned.

They would discuss how to stop the heroes. Bowser would suggest kidnapping.

"Haven't you already tried that?" asked Eggman.

"Can't really argue with kidnapping - it's tradition." Bowser would reply.

"That's not tradition!" said Eggman, "Doing the same thing over and over again to expect different results is the definition of insanity."

Bowser knowingly crossed his arms.

"Just like you when you fail to get rid of the hedgehog."

If the live action Eggman decided to do the floss dance Bowser would greatly disapprove of it. Bowser would show Eggman how it’s done with some of his own break dancing skills based on the D.D.R. Mario Mix game.

Eggman would also be shocked to learn that Bowser has a musical talent in rock and roll. The scientist displays his robots using A.I. that can play music too.

“A machine doing music is nothing compared to a real person making it.” said Bowser, "Learning by practice to being a better player is what true art is all about."

Eggman would want to use an element of surprise by switching things up against their heroes by recommending that Bowser fight the Sonic Gang while the scientist face the Mario Bros. He’ll need enough data about the cartoony plumbers (perhaps information about Bowser secretly in case of a double cross were to happen) to combat them.

#eggman #bowser #mario bros #sonic the hedgehog #head canon #remember that gba crash and spyro crossover?#Wish those older games were executed better #The concept of N. Cortex fighting Spyro and Ripto going against Crash is interesting

Emerging Trends in Pharmaceutical Education

Pharmaceutical education is experiencing a transformative shift in response to rapid advancements in the field of healthcare and the evolving needs of the global population. As we step into a future characterised by personalised medicine, precision therapies, and breakthrough technologies, the training and education of future pharmacists and pharmaceutical professionals are adapting to keep pace. In this blog, we will bring forth the latest developments and emerging trends in pharmaceutical education.

According to Statista Pharmaceutical Market Forecast, the pharmaceutical industry has witnessed a rapid metamorphosis, with revenue expected to show an annual growth rate (CAGR 2023-2028) of 5.80%, resulting in a market volume of US$1,478.00bn by 2028, reflecting the sector's exponential growth. This growth is propelled by various factors, including an aging population, the rise of chronic diseases, and the increasing demand for personalised treatments. In response, pharmaceutical education is adapting to equip aspiring pharmacists and professionals with the skills and knowledge needed to navigate this dynamic and ever-evolving industry.

1. Integration of Technology and Digital Learning

In recent years, the integration of technology into pharmaceutical education has become ubiquitous.

This approach optimizes comprehension and retention, ensuring that each student achieves their educational goals.

4. Integration of Pharmacogenomics and Genetics

Advancements in pharmacogenomics and genetics are transforming pharmaceutical education by necessitating a deeper understanding of how genetic variations influence drug responses. Modern curricula are incorporating in-depth studies of genomics, pharmacogenomics, and genetic testing to equip future pharmacists with the knowledge and skills to provide personalized medication recommendations based on an individual's genetic makeup. This personalized approach improves patient outcomes and reduces adverse reactions.

5. Emphasis on Soft Skills and Professionalism

Pharmaceutical education is evolving to place greater emphasis on soft skills and professionalism. Effective communication, leadership, critical thinking, and empathy are essential qualities for pharmaceutical professionals. Educational programs now integrate courses and workshops that enhance these skills, preparing students not only to excel in their technical roles but also to effectively interact with patients, colleagues, and healthcare stakeholders.

6. Experiential Learning and Practical Exposure

Traditional classroom-based learning is being complemented with experiential learning and practical exposure in real-world healthcare settings. Internships, externships, and rotations in community pharmacies, hospitals, research laboratories, and pharmaceutical industries provide students with valuable hands-on experience. These opportunities bridge the gap between theory and practice, enabling students to apply their knowledge in real-life scenarios and develop the necessary skills and confidence for their future careers.

7. Environmental and Global Health Perspectives

As sustainability and global health become paramount concerns, pharmaceutical education is incorporating curricula that address the environmental impact of pharmaceuticals and global health challenges.
