Tadej Pogačar dominates Giro dItalia Queen stage leads overall race by almost seven minutes

In short: Tadej Pogačar dominated the Queen stage of this year’s Giro d’Italia, beating his nearest rivals by almost three minutes Pogačar leads the overall standings by six minutes and 41 seconds from Welshman Geraint Thomas.What’s next? The Giro has a rest day on Monday before the final stage in Rome next Sunday. Slovenian star Tadej Pogačar said he wanted to win the Queen stage of the Giro d’Italia. On Sunday he did just that — destroying his rivals on the toughest leg of this year’s race to add three minutes to his already considerable advantage. There is just one week remaining of the Italian grand tour. Despite having ridden for more than six hours through the high mountains on Sunday, Pogačar was full of smiles as he was cheered on by the crowds lining the difficult summit finish at Livigno. As the sunshine glinted off the snow on the sides of the route, Pogačar crossed the finish line with his arms outstretched over his head. “Today was one of the best days, I would not say that it was the best day of my career but it was a really nice stage, really good route, nice climbs,” Pogačar said. “The team did a super good job. “We had this stage in mind since December or whatever.” Pogačar finished the 15th stage 29 seconds ahead of Nairo Quintana and 2:32 ahead of third-place Georg Steinhauser. Tadej Pogačar’s rivals trailed up the mountaintop finish over three minutes in arrears. (Getty Images: Dario Belingheri) His closest rivals, including Australian Ben O’Connor, were nearly three minutes slower. With the bonus seconds he picked up, Pogacar now leads the Giro by 6:41 over Geraint Thomas, with Daniel Martinez 6:56 behind in third, while O’Connor remains fourth, 7:43 behind. Two-time Tour de France winner Pogačar is targeting the Giro-Tour double this year. With just six stages left after Monday’s rest day, he is well set to complete the first step. It was a fourth stage win for Pogačar in his Giro debut but the UAE Team Emirates rider had made no secret that he was targeting the Queen stage, which is the name given to the hardest leg of the race. There were five categorised climbs — including the fearsome Passo del Mortirolo — and 5,200 meters of elevation on the 222-kilometre leg from Manerba del Garda to Livigno and the arrival at Mottolino, where the last 1,800 metres was on asphalt along a ski slope with 18 per cent gradients. Pogačar made his move with 13.9 kilometres remaining and none of the other GC contenders could follow him. At that point he was just over three minutes behind sole leader Steinhauser, who was on the verge of getting caught and then passed by Quintana. Pogačar quickly swept up the remnants of the breakaway — which had been 50 strong earlier in the day — before blasting past Steinhauser toward the top of the penultimate climb and heading off in pursuit of Quintana. The back of Tadej Pogačar is what most of his opponents have seen this Giro — if they can get close enough.(AP: LaPresse/Marco Alpozzi) He passed the 2014 Giro winner with 1.9 kilometres remaining and was untroubled on the steep climb to the finish. “I gave it my all in the 10 or 15km,” Pogačar said. “I’m super happy that I can win a queen stage in Livigno, one of my favourite places in Italy.” After the rest day, Tuesday’s 16th stage is another one where Pogačar could put even more time on his rivals as the race heads from the Alps into the daunting Dolomites. The now 206-kilometre route from Livigno to Santa Cristina Val Gardena has been altered because of a high risk of avalanches on the Stelvio. The riders will still go partly up the famed ascent but to 2,489 metres instead of 2,758. That will nevertheless still be the highest point of this year’s race. The peloton will then instead head along another pass into Switzerland before rejoining the original route. The Giro ends in Rome next Sunday.

Conservative agenda dominates Texas, despite Democratic hopes of turning the state blue Still, Trump’s lead in Texas was the narrowest for a Republican presidential candidate in years. In 2012, Mitt Romney won the state by 16 points. In 2016, Trump won by 9 points. And with only a few days left in the session, lawmakers are still trying to push an election overhaul with new voting restrictions and legislation that would ban the teaching of critical race theory, among other agenda items. The state is changing demographically and is set to gain two congressional seats in the upcoming redistricting process, due to the state’s rapid population growth over the past decade. While some Republicans are on edge about the future of the party, many of its state leaders see the GOP’s success in Texas last cycle as a mandate to continue moving to the right. Republicans also tout the gains that Trump made in the typically Democratic stronghold of South Texas, flipping several counties that voted for Clinton in 2016 and making massive inroads in others. Of the 17 counties that Clinton won in 2016, Trump took back seven of them. In Starr County, along the southern border, for example, Trump had lost to Clinton by 60 percentage points. But in 2020, he lost to Joe Biden by only 5 percentage points in the same county. “For every Karen we lost in the suburbs, we gained a Julio,” said one GOP operative in the state. ‘I don’t want to be roadkill’ Lt. Col. Allen West walked across the street of an affluent neighborhood in a Dallas suburb, followed by a throng of supporters who gathered at a fundraiser to meet the former congressman who’s now chairman of the Texas Republican Party. He came outside for an interview — CNN had been initially invited to the event but was escorted off the property upon arrival — as dozens of donors surrounded him. He was there to speak to The Southlake Families PAC, a group that funded school board candidates who opposed teaching critical race theory in a local election that gained national attention. West, who helped spearhead the GOP agenda for the legislative session, pushed back at critics who think the Legislature is shifting too far to the right. He pointed to the droves of people moving to Texas from traditionally blue states like California, New York and New Jersey as examples of the party’s success in policy. “Texas is a strong, successful, constitutional conservative red state,” he said. As for concerns that the agenda might push away middle-of-the-road voters, West used an old political trope. “You know what my dad taught me?” he said. “I grew up in Georgia. He said the only thing in the middle of the road is roadkill, and I don’t want to be roadkill.” It’s a sentiment underwritten by Trump’s still influential and unabashed style. Many of the state’s leaders, who are up for reelection next year, are keenly aware of the power he continues to hold over the party, especially with potential endorsements. Attorney General Ken Paxton, who could soon be facing a primary challenge from Texas Land Commissioner George P. Bush, is among the former President’s biggest allies. He helped lead a lawsuit alleging election fraud in four states that was ultimately rejected by the Supreme Court. Trump said in a statement that he’ll be making an endorsement in the primary race, which Bush is expected to join next week. Even Bush, whose family, critical of the former President, has been routinely maligned by Trump in recent years, has shown support for him. “I like them both very much,” Trump said in the statement Tuesday. “I’ll be making my endorsement and recommendation to the great people of Texas in the not-so-distant future.” Trump’s baseless claims that the election was stolen still loom large nationwide and here in Texas. For his part, West attended a “Stop the Steal” rally in Dallas after the election and refuses to acknowledge that Joe Biden got more votes than Trump. When asked three times about the election results in November, West responded with the same carefully crafted answer: “I believe that there were unconstitutional actions that led to nefarious things that happened in five battleground states.” ‘It’s a really weird place to be in’ Democratic state Rep. Donna Howard has been representing the Austin area in the Texas Legislature since 2006. She fought hard this year against the abortion bill, and she joined fellow Democrats onstage late Tuesday night to celebrate one of the few victories her party had this year: running out the clock on a bill that would prevent transgender students from playing on sports teams that aligned with their gender identities. “We’ve just swung totally to the right,” she said, standing outside her office underneath the state Capitol and reflecting on the past few months of the legislative session. “It’s been like steamrolling of all these red meat wedge issues and not focused on what we came in here to deal with.” Howard acknowledged Texas is still a red state but was among those who had expected Democrats to do better here in the 2020 election, especially after they performed well in the state in 2018 and Beto O’Rourke came close to defeating incumbent GOP Sen. Ted Cruz. Like many Democrats, Howard argued that her party suffered in 2020 from adhering to social distancing guidelines and not doing the kind of in-person door knocking and grassroots politicking that can be so effective. They’re already focused on trying to regain momentum for the 2022 midterm elections. “The blue wave is growing,” she said. “But I don’t know when it’s actually going to get here.” That’s in large part because primaries are king in Texas. Very few state lawmakers have competitive general elections, so courting the base is still the main objective for most politicians. “There’s no real political incentive for those in the state House or in the state Senate, who are Republicans, to do anything but appeal to the base,” said Brendan Steinhauser, a veteran GOP strategist in the state. “They’re not having to necessarily wage a competitive general election campaign, and so until that changes — and we are seeing trends that that’s going to happen — I think you’ll continue to see this out of our state Legislature,” he added. Steinhauser ran the campaign for Michael Wood, an anti-Trump Republican who competed and lost in this month’s special election to replace Republican Rep. Ron Wright of Arlington. Wright died from Covid-19 in February, and Trump endorsed his widow, Susan Wright, who has advanced to a runoff this summer for the final election. While many Republicans, like Allen West, think that Trump steered the party in the right direction, some conservatives, like Steinhauser, are concerned that as the electorate in Texas becomes younger and more diverse, Republicans will have problems. For Steinhauser, that fear of a blue wave down the road is very real. “We find ourselves having been very successful in the last cycle, but also kind of worried about the long-term future of the party, worried about demographic changes,” he said. “It’s a really weird place to be in.” Source link Orbem News #agenda #Blue #Conservative #ConservativeagendadominatesTexas #Democratic #despiteDemocratichopesofturningthestateblue-CNNPolitics #dominates #hopes #Politics #state #Texas #turning

Mysterious launch of radioactive materials throughout Europe in 2017 ‘likely arrived from Russian nuclear reprocessing plant’

A cloud of the radioactive isotope ruthenium-106 appeared in September 2017

Professionals studied 1,300 measurements from 176 stations in 29 different countries 

The leak’s nature and distribute helps make the Mayak nuclear facility the probable source 

Irrespective of its unconventional mother nature the cloud under no circumstances threatened human health in Europe

A Russian nuclear reprocessing plant is the likely source of the mysterious cloud of radioactive ruthenium-106 that distribute across Europe in 2017, industry experts said.

At its most extreme, the cloud’s radiation amounts arrived at 176 millibecquerels for every cubic meter of air — 100 periods higher than mentioned in Europe following the Fukushima meltdown.

The specific resource of the cloud had been unsure — although the highest radiation degrees were detected in Russia, the Federation has denied accountability for the leak.

A Russian nuclear reprocessing plant is the very likely resource of the mysterious cloud of radioactive ruthenium-106 that unfold across Europe in 2017, authorities explained

RUTHENIUM 106

Ruthenium is aspect of the platinum group of metals.

It is a really hard, silvery-white metal with a shiny floor.

Its melting point is about 2,300 to 2,450°C (4,200 to 4,400°F)

Its discovery is credited to Polish chemist Jedrzej Sniadecki, who declared the declared the discovery of the factor in 1808.

Chemists had been not able to verify Sniadecki’s work and, as a final result, the aspect was rediscovered twice additional in later on a long time.

The major makes use of of ruthenium are in alloys and as catalysts for industrial procedures.

Ruthenium-106 is an isotope, or variant with a different amount of neutrons in its nucleus, utilized for radiation remedy to deal with eye tumours.

It is from time to time as a source of electricity, recognized as radioisotope thermoelectric turbines, applied to power satellites.

The radioactive isotope has a half-daily life of 374 days.

In get to pin down the origins of the incident, radiation specialist Georg Steinhauser of the University of Hanover, Germany and colleagues analysed additional than 1,300 measurements of the cloud taken from across Europe and past.

These recordings were taken across 176 measuring stations in 29 various international locations, reflecting the extensive geographic distribute of the cloud, which not only covered significant components of Europe but achieved as significantly as the Arabian Peninsula, Asia and the Caribbean.

‘We measured radioactive ruthenium-106,’ reported Professor Steinhauser.

‘The measurements point out the biggest singular release of radioactivity from a civilian reprocessing plant.’

The group attained this summary dependent on the reality that — unusually — the only radioactive compound calculated from the release was ruthenium.

‘We had been equipped to display that the incident transpired in the reprocessing of put in gasoline aspects, at a pretty sophisticated stage, shortly before the stop of the method chain,’ said Professor Steinhauser.

‘Even even though there is now no formal assertion, we have a pretty fantastic idea of what might have happened.’

By combining the distribution pattern of the radioactive content with atmospheric modelling, the team have concluded that the cloud was unveiled from within just the Southern Urals — wherever the Russian Mayak nuclear processing facility is situated.

To day, no nation has claimed duty for the release of radioactive product — with Russia owning regularly denied acquiring experienced any involvement in the emission. 

The Mayak facility is no stranger to nuclear release, owning beforehand emitted a person of the largest historical radiation leaks in the September of 1957 — greater that the launch from the Fukushima meltdown and second only to the Chernobyl disaster. 

By combining the distribution pattern of the radioactive material with atmospheric modelling, the team have concluded that the cloud was introduced from within the Southern Urals — where the Russian Mayak nuclear processing facility, pictured, is located

The root of the 1957 incident was the explosion of a tank complete of liquid squander created as a byproduct of plutonium production. 

At that time, a tank that contains liquid squander from plutonium production experienced exploded, resulting in significant contamination of the place. 

The researchers have dated the time of the 2017 launch to in between 18:00 on September 25 and 12:00 on September, 26 — just about 60 yrs exactly immediately after the 1957 incident.

According to Professor Steinhauser, the incident ‘was a pulsed release that was above really swiftly.’

In distinction, the leaks from Chernobyl and Fukushima went on for days. 

Even even though the release was abnormal, the radioactive substance did achieve a significant ample concentration any place in Europe to be detrimental to human wellbeing.

The comprehensive conclusions of the examine were being revealed in the journal PNAS.

"average young german rider performs pretty well at the 2024 giro d'italia a year" factoid actualy just statistical error. average young german rider has a mediocre performance at the 2024 giro d'italia. Steinhauser Georg, who was in a strong breakaway for 176km and came 3rd on the 222km 6hr+ queen stage, is an outlier adn should STILL be counted because it was an amazing effort

Advances in Research on Fetal Alcohol Spectrum Disorders

Fetal alcohol spectrum disorders (FASD) are the broad range of neurodevelopmental and physical effects that result from prenatal exposure to alcohol. People with FASD may have facial abnormalities and growth impairments, but the most profound effects are cognitive and behavioral deficits. These deficits can contribute to lifelong learning disabilities, poor social skills, and other problems that impact daily functioning (e.g., living independently or holding a job), as well as overall health and well-being. A significant public health problem, FASD affect an estimated 1 to 5 percent of first-grade children in the United States, according to a 2018 study supported by the National Institute on Alcohol Abuse and Alcoholism (NIAAA) that was conducted by the Collaboration on Fetal Alcohol Spectrum Disorders Prevalence (CoFASP) and published in the Journal of the American Medical Association.

“Research on FASD is a priority for NIAAA, and for many years we’ve supported studies to understand how alcohol disrupts prenatal development and how FASD can be prevented, diagnosed, and treated,” says NIAAA Director George F. Koob, Ph.D. “Basic, translational, and clinical research are providing valuable insight into the mechanisms that underlie the learning deficits and health problems associated with FASD, thereby shedding light on potential intervention strategies.”

For example, in a recent study led by Wolfram Goessling, M.D., Ph.D., and Olivia Weeks at Harvard Medical School, researchers reported a connection between prenatal alcohol exposure and metabolic disorders in adults. Their analyses of a patient database at a large academic health system found that adults with FASD had an increased incidence of type 2 diabetes, lower HDL (“good”) cholesterol levels, and elevated triglyceride levels compared to those without FASD. Low HDL cholesterol and elevated triglyceride levels are associated with increased risks of stroke and heart attack.

The researchers also investigated the relationships between metabolic dysfunction and prenatal alcohol exposure using a zebrafish model of FASD. When they examined alcohol-exposed zebrafish at adulthood, they found that a high-fat, high-cholesterol diet resulted in obesity and high glucose levels in male but not female zebrafish. High blood glucose is an indicator of diabetes in humans. The researchers also found an association between increased abdominal fat and abnormal liver development in the adult alcohol-exposed zebrafish, suggesting that the molecular mechanism for such alcohol-related pathology is a highly conserved in zebrafish and an evolutionarily basic component of physiology.

Given that alcohol is frequently used with other substances, NIAAA-supported scientists are investigating the combined effects of prenatal exposure to alcohol and substances such as tobacco. As part of the multisite Prenatal Alcohol in SIDS and Stillbirth (PASS) Network, investigators from the United States and South Africa recently reported that children born to mothers who both drank and smoked beyond the first trimester of pregnancy have a twelvefold increased risk for sudden infant death syndrome (SIDS)—the sudden, unexplained death of an infant younger than 1 year—compared to those who were unexposed or only exposed in the first trimester of pregnancy. Dual exposure to alcohol and tobacco was associated with substantially higher risk than exposure to either substance alone, suggesting that combined exposures to alcohol and tobacco have a synergistic effect on SIDS risk.

In another recent NIAAA-supported study, Kazue Hashimoto-Torii, Ph.D., of the Children’s National Research Institute in Washington, D.C., and colleagues investigated the molecular mechanisms that contribute to the motor deficits associated with prenatal alcohol exposure. Previously, the researchers showed that prenatal alcohol exposure was associated with differences in expression of nearly 100 genes. More recently, they focused on the increased expression of a gene, known as Kcnn2, which encodes a protein involved in regulating neuron activity in brain systems associated with learning1 in the motor area of the cerebral cortex in a mouse model of FASD. The researchers demonstrated that increased Kcnn2 expression correlated with deficits in motor skill learning caused by prenatal alcohol exposure. They also observed improvements in these learning deficits when a drug was administered to inhibit activity of Kcnn2, suggesting that Kcnn2 inhibitors may be a potential pharmacological intervention for certain learning disabilities in FASD.

NIAAA-supported clinical research is also focused on developing interventions to mitigate the adverse effects of prenatal alcohol exposure. Researchers at the University of Minnesota and colleagues have been investigating whether supplementing the diet with choline during early childhood brain development could improve memory and executive function in children with FASD. Choline is an essential nutrient with a key role in myelination2 and is known to impact brain development and cognition. In a previous study led by Jeffrey Wozniak, Ph.D., the researchers showed that choline supplementation is feasible and tolerable with minimal side effects among 2- to 5-year-old children who were prenatally exposed to alcohol. In their recently published, 4-year follow-up study on the choline recipients, researchers report that children who received choline had better nonverbal intelligence, visual-spatial skills, and working and verbal memory, as well as fewer symptoms of negative behavior compared to the children who did not receive choline. It is important to note that these effects were evident years after choline administration had ended, suggesting that developmental trajectories had been altered.

“Prenatal alcohol exposure contributes to an array of lifelong physical, cognitive, and behavioral problems,” says Dr. Koob. “These detrimental effects highlight the need for strategies to improve FASD prevention, screening, diagnosis, and treatment. NIAAA’s recent efforts towards the development of a consensus FASD overarching research classification system could accelerate progress in these areas.”

1Kccn2 stands for potassium intermediate/small conductance calcium-activated channel, subfamily N, member 2, and is a gene that encodes a protein channel involved in regulating neuronal excitability in brain systems associated with learning.

Georg Steinhauser ganó en solitario la etapa 17ª del Giro de Italia 2024

el alemán de 22 años se impuso luego de su segundo intento de fuga este miércoles.

Steinhauser de 22 años se confirma como una de las revelaciones de este Giro. El pasado domingo ya fue tercero en otra jornada montañosa, finalizando tercero en la etapa reina que terminó en Livigno.

Recordemos que el Georg Steinhauser el día domingo lideraba la etapa cundo salió en la fuga y fue superado por Nairo Quintana a falta de 13 kilómetros de la meta, hoy tres días después se metió en la fuga que inexplicablemente fue controlada por el DCM.

Cuando faltaban 59 kilómetros Steinhauser lo volvió a intentar donde nadie fue por el y así pudo ganar la etapa 17 del giro de Italia 2024.

Segun dijo el alemán a la prensa internacional sintió algo de nervios cuando le avisaron que a falta de 2 kilómetros Pogacar había atacado, pero sabía que tenía Buena ventaja y le dio para ganar la etapa, además el esloveno no salió como para ganar la etapa.

Estas fueron las palabras de Pogi.“Enhorabuena para él, ha hecho una etapa increíble”, aplaudió Pogacar al ganador de la etapa, vaticinando que será “un gran corredor” de aquí en adelante hay que seguir la carrera de este excelente corredor que promete mucho.

Explore photography’s history with these rare cameras

It's easy to take camera technology for granted in a time when everyone walks around with a computational photography machine in their pocket, but camera design has come a long way since the camera obscura and Nicéphore Niépce's early experimentations with silver chloride coated paper in 1860. In Focus: The Camera, which is currently on view at The Getty, takes an in-depth look at some of these technological advancements with a selection of twenty cameras that span the 1800s to the mid '90s. The cameras are presented alongside self-portraits made by photographers and images made of photographers at work.

“I wanted to remind our visitors about the people behind the cameras,” says curator Paul Martineau, associate curator at the Getty Museum, “Those who made use of this continually evolving technology to create artworks of great sophistication or to record history as it was unfolding before the lens.”

The oldest camera on view in In Focus: The Camera is a Camera Obscura from the early 1800. The most recent included in the exhibition is an Apple Quick Take 100 from 1994, one of the very first mass-marketed digital cameras. Daguerreotype cameras, a stereo camera, and a miniature spy camera are also some of the rare pieces of technology on display. Of the 20 cameras on display, Martineau says that one of his favorites is the Semmendinger mammoth plate camera from the late 1800s.

“It is big and beautiful,” he says. “I set it on a pedestal in the middle of the gallery and trained its lens on the entrance. That way, people would feel as though they were a camera subject, so to speak, as they came in.”

In Focus: The Camera is on view at The Getty in Los Angeles through Jan. 5, 2020.

Russia’s Last Nuclear Mishap Shows Cover-Ups Are Becoming Harder

(Bloomberg) -- The shroud of mystery surrounding Russia’s latest deadly nuclear accident will become increasingly difficult to maintain once the data starts to roll in.That’s the lesson of a team of scientists who showed last month -- days before the Aug. 8 explosion that killed five Russians -- that “a sizeable, yet undeclared nuclear accident” had occurred two years earlier in Russia, possibly from a nuclear-fuel facility once used to manufacture plutonium for weapons.In a report for the U.S. National Academy of Sciences published July 26, the team reconstructed data to demonstrate why it’s becoming harder to suppress information about nuclear accidents. New radiation-detection networks, satellite constellations and even social-media streams all help to open novel pathways to pry into states’ most closely held secrets.“Here we see the powerful nature of an independent, science-based network,” said Georg Steinhauser, one of the report’s lead authors.Cold WarRadio-chemistry techniques used to reverse-engineer nuclear incidents are nothing new. During the Cold War they were the domain of intelligence programs that operated under code names like Dragon Return or Bluenose. They deployed global detection networks to sniff out and collect radioactive particles released by atomic tests in order to get restricted information out from behind the Iron Curtain.What’s changed since the demise of the Soviet Union is that new layers of highly-sensitive detection technologies have been added to global monitoring networks and that much of the data being generated is available to researchers, according to Jeffrey Lewis of the James Martin Center for Nonproliferation Studies.“We live in an era of data ubiquity,” said Lewis, who routinely uses satellite imagery and models once only available to intelligence services. “Researchers can use different streams to confirm each other and build a surprisingly comprehensive picture based on public information.”One of the most powerful detection networks available is run by the Comprehensive Test-Ban Treaty Organization. The Vienna-based body operates a $1 billion international array of some 320 stations spread around the globe, which monitor the air, land and sea for signs of nuclear explosions. CTBTO data was instrumental in both the National Academy of Science report about the 2017 Russian incident, as well as this month’s accident 1300 kilometers (800 miles) north of Moscow.Russia has provided little information about this month’s blast involving a failed missile test, which killed five atomic scientists and was followed by reports of a brief spike in local radiation levels. President Vladimir Putin’s chief spokesman, Dmitry Peskov, dismissed a simulation tweeted by the CTBTO chief showing how the nuclear particles would have moved across Russia, telling reporters this week that “a map of how a radioactive plume could spread after the accident -- the wording itself is quite absurd.”Chernobyl DeceptionToday’s network of radiation-detection monitors are largely as a result of Russian deception following the 1986 meltdown in Chernobyl, according to Steinhauser. European researchers responded by setting up an independent network they call the Ring of Five that “will always remain online and ready,” he said.The National Academy of Sciences report used data compiled by the CTBTO and European regulators to trace the origins of a 2017 plume of radioactive material that spread across Eurasia.
