By Suzanne Burdick, Ph.D.

Editor’s note: This is the third in a three-part series investigating why the U.S. government ended studies on the biological effects of wireless radiation. Part 1 covered the expert opinion of John Bucher, Ph.D. Part 2 covered results from Children’s Health Defense’s FOIA request to the National Institutes of Health for records related to the studies.

In January 2024, the National Toxicology Program (NTP) announced it had no plans to further study the effects of cellphone radiofrequency radiation (RFR) on human health — even though the program’s own $30 million study found “clear evidence” of cancer and DNA damage.

In April 2024, Children’s Health Defense (CHD) filed requests to the National Institutes of Health (NIH) under the Freedom of Information Act (FOIA) to obtain records related to why the government shut down the research — NIH produced records that included 2,500 fully redacted pages.

As part of The Defender’s ongoing investigation into why the government shut down its studies on wireless radiation, CHD FOIA’d all emails related to communications among key NTP officials and researchers from Feb. 1, 2023, to Feb. 1, 2024.

However, the NIH produced only 14 emails — none of them revealed who made the decision to stop the research or provided detailed information about why the research was halted.

"...So we decided to combine the two. A war machine cannot function without both parts, in my estimation. My lead programmer, Avanti Tynshu, was in full agreement. Chief Mechanic Garsad was only opposed on the grounds that it may achieve a desire to slaughter its 'masters'. I assured him that not only would self-destruct measures would be in place just in case, but that the Non-Troll-Persona (NTP, a fitting descriptor for what is neither truly AI nor sole biotechnological growth) would be restrained in terms of intelligence."

"An artificial intelligence depends on the skills of its programmer, and in many instances is woefully insufficient. "AI" has been used by layfolk as a solution for anything, but in realistic terms it is impossible to give something enough intelligence in such a small area that it could feasibly operate at war. Military drones operate with AI, and their tactics are brutally simple. You don't need a lot of effort to program something to detonate a massive bomb wherever the target is. These machines, our Legionnaires, have to operate with more finesse. Therefore, in partnership with an unnamed party (withheld for their security), we are developing the NTP project to allow for tactical thinking and decision-making without the need for a server the size of a building."

"There are, of course, rumors of similar things out there. Constructs gone wild with their personalities. I cannot speak as to their design, if real, but NTPs are designed to be simple and below sapience. There will be limits placed on their capacity to, for lack of a better term, feel. This will prevent unneeded complications and serve as a barrier to full scale rebellion."

"I am no philosopher, but I have to pause to wonder at the implications of this. Would this be considered a sort of Flowers for Algernon scenario? Could these NTPs achieve the full emotional range without these blocks? This is a question for someone else. I feel that the true error would be to even seek these answers. Even so, when using NTPs, it is recommended to treat them less as tools and more as trusted servants. Being 'kind' is a cheap price for ensuring that even their limited feelings do not drift towards antipathy for whom they are forced to serve."

"All that written, it still remains to be seen what the final result is. For all I am aware at this time, the result could be something entirely unremarkable. Such is the nature of this work."

Synchronized Bell System

A Healthcare Facility Clock with Countdown Timer

A medical facility clock need to be exact and reproduced continually throughout a whole center in order to avoid timing mistakes and possible legal effects. The hospital clock is relied upon to be simultaneous with all various other clocks to prevent lag times among them, which or else could present mistakes in getting examination lab results, in dispensing drug, or documenting person data. Here we take a look at technological alternatives for realizing effective integrated clock systems.

The medical facility clock is additionally used in the operating room and somewhere else where elapsed time has to be thoroughly tracked. This implies that a timer is frequently made use of in various means to count up or count down during treatments. This capacity is extremely preferable in the facility for at the very least some wrist watches.

Due to the fact that the medical facility tends to be a hectic-paced environment, its procedures require to be structured as high as possible. To make the clocks part of this goal, one should choose those that are (basically) free of upkeep, not calling for any human intervention. This rule implies that their power must not be derived from batteries preferably (as they should be transformed regularly), even if no outlet is nearby, and that their electric motors ought to readjust automatically for changes in daylight savings.

These capabilities are readily available in today's timepieces and being made use of. An extra capacity that is very desirable in a medical facility is systematic synchronization of all clocks, often tied to the local area network, which makes each time reference precise no matter where it reads. This is particularly helpful when people and/or their files transfer among numerous wards throughout their check out.

Synchronization can be achieved in generally three various means. Possibly the most popular selection is a wireless time system in which messages or signals are broadcast wirelessly to every appear the facility, therefore integrating the moment and sending out other interactions. Procedures are generally established to stop troubles from prospective superhigh frequency disturbance.

A second method to integrate the clocks is to tie them to the computer network straight, therefore piggy-backing off the network's very own synchrony, which is maintained exact automatically to within microseconds. The third approach is to use Power Over Ethernet (POE) in addition to Web Method (IP). This is one way to power each clock when electrical outlets aren't offered (as long as Ethernet connections are readily available); Ethernet also makes use of Network Time Method (NTP), which was made to manage variable-latency interactions, to specifically synchronize the moment.

We desire currently to concentrate on just how countdown innovation is used-- and typically required-- in a bargain of operating procedures. The timers include numerous mode options, including the most fundamental among simply presenting the day and/or time. The other settings perform checking, either up or down, with either a details period or a specified end date and time target.

The instructions of matter is primarily a matter of specific preference, based upon a preference to either begin or end at zero. For normal usage, one programs in the period and launches the timer manually.

For the designated end-point setting, the lapsed duration is of less significance than the accurate minute of arrival noting some event, such as setting off an action. This setting is actually equivalent to an alarm. Nevertheless, the screen is counting in the direction of that minute and thus shows its relative nearness for simple recommendation. synchronized clocks for hospitals

Procedure time markers need to be in synchrony with the institutional time; this can be crucial for anesthetization or the providing of medicine at precisely the right time. We have actually seen the discomforts taken to guarantee facility-wide synchronization of all watches and local area network. But we have likewise discovered the value originated from having a healthcare facility clock with countdown timer.

The future of space exploration includes some rather ambitious plans to send missions farther from Earth than ever before. Beyond the current proposals for building infrastructure in cis-lunar space and sending regular crewed missions to the Moon and Mars, there are also plans to send robotic missions to the outer Solar System, to the focal length of our Sun’s gravitational lens, and even to the nearest stars to explore exoplanets. Accomplishing these goals requires next-generation propulsion that can enable high thrust and consistent acceleration. Focused arrays of lasers – or directed energy (DE) – and lightsails are a means that is being investigated extensively – such as Breakthrough Starshot and Swarming Proxima Centauri. Beyond these proposals, a team from McGill University in Montreal has proposed a new type of directed energy propulsion system for exploring the Solar System. In a recent paper, the team shared the early results of their Laser-Thermal Propulsion (LTP) thruster facility, which suggests that the technology has the potential to provide both high thrust and specific impulse for interstellar missions. The research team was led by Gabriel R. Dube, an Undergraduate Research Trainee with the McGill Interstellar Flight Experimental Research Group (IFERG), and Associate Professor Andrew Higgins, the Principal Investigator of the IFERG. They were joined by Emmanuel Duplay, a graduate researcher from the Technische Universiteit Delft (TU Delft); Siera Riel, a Summer Research Assistant with the IFERG; and Jason Loiseau, an Associate Professor with the Royal Military College Of Canada. The team presented their results at the 2024 AIAA Science and Technology Forum and Exposition and in a paper that appeared in the AIAA journal Aerospace Research Central (ARC). Artist’s concept of a Bimodal Nuclear Thermal Rocket in Low Earth Orbit. Credit: NASA Higgins and his colleagues originally proposed this concept in a 2022 paper that appeared in Acta Astronautica – titled “Design of a rapid transit to Mars mission using laser-thermal propulsion.” As Universe Today reported at the time, the LTP was inspired by interstellar concepts like Starshot and Project Dragonfly. However, Higgins and his associates from McGill were interested in how the same technology could enable rapid transit missions to Mars in just 45 days and throughout the Solar System. This method, they argued, could also validate the technologies involved and act as a stepping stone toward interstellar missions. As Higgins told Universe Today via email, the concept came to them during the pandemic when they were unable to get into their lab: “[M]y students did a detailed conceptual study of how we could use the kind of large laser arrays envisioned for the Breakthrough Starshot for a more near-term mission in the Solar System. Rather than at 10-km-diameter, 100-GW laser envisioned for Breakthrough Starshot, we limited ourselves to a 10-m-diameter, 100-MW laser and showed it would be able to deliver power to a spacecraft out to nearly the distance of the Moon. By heating hydrogen propellant to 10,000s of K, the laser enables the “holy grail’ of high thrust and high specific impulse.” The concept is similar to nuclear-thermal propulsion (NTP), which NASA and DARPA are currently developing for rapid transit missions to Mars. In an NTP system, a nuclear reactor generates heat that causes hydrogen or deuterium propellant to expand, which is then focused through nozzles to generate thrust. In this case, phased-array lasers are focused into a hydrogen heating chamber, which is then exhausted through a nozzle to realize specific impulses of 3000 seconds. Since Higgins and his students returned to the lab, he said, they have been attempting to experimentally verify their idea: “Obviously, we don’t have a 100 MW laser at McGill, but we now have a 3-kilowatt laser set-up in the lab (which is scary enough) and are studying how the laser would couple its energy to a propellant (eventually hydrogen, but for now argon just because it is easier to ionize). The AIAA paper reports on the design, construction, and ‘shake-down’ of our 3-kW laser facility.” Artist’s impression of a directed-energy propulsion laser sail in action. Credit: Q. Zhang/deepspace.ucsb.edu Higgins and his team constructed an apparatus containing 5 to 20 bars of static argon gas from their tests. While the final concept will utilize hydrogen gas as a propellant, they used argon gas for the test because it is easier to ionize. They then fired the 3-kW laser in pulses at a frequency of 1070 nanometers (corresponding to the near-infrared wavelength) to determine the threshold power necessary for Laser-Sustained Plasma (LSP). Their results indicated that around 80% of the laser energy was deposited into the plasma, which is consistent with previous studies. The pressure and spectral data they acquired also revealed the peak LSP temperature with the working gas, though they stress that further research is needed for conclusive results. They also stressed that a dedicated apparatus is needed to conduct forced flow and other LSP tests. Lastly, the team plans to conduct thrust measurements later this year to gauge how much acceleration (delta-v) and specific impulse (Isp) a laser-thermal propulsion system can deliver for future missions to Mars and other planets in the Solar System. If the technology is up to the task, we could be looking at a system capable of delivering astronauts to Mars in weeks rather than months! Other concepts selected for the NIAC this year include tests to evaluate hibernation systems for long-duration missions in microgravity. Alone or in combination, these technologies could enable fast-transit missions that require less cargo and supplies and minimize astronaut exposure to microgravity and radiation.

Rust Compiler Performance Triage

A difficult week for triage, due to what appears to be system-level disruption to measurement apparatus, yielding transient noise (and potentially masking actual problems). The main non-noise performance change was huge regression to bitmaps introduced by PR 117131, and that already has a fix in-flight fix (PR #117542). The other thing worth noting is that the parallel rustc front-end has been enabled in the nighlty builds, which has introduced some overhead that was expected by wg-parallel-rustc.

Triage done by @pnkfelix. Revision range: 650991d6..7b97a5ca

10 Regressions, 4 Improvements, 3 Mixed; 3 of them in rollups 68 artifact comparisons made in total

Quote of the Week

For Binder to continue to meet Android's needs, we need better ways to manage (and reduce!) complexity without increasing the risk.

The biggest change is obviously the choice of programming language. We decided to use Rust because it directly addresses a number of the challenges within Binder that we have faced during the last years.

– Alice Ryhl on the Linux Kernel Mailing List

Thanks to Vincent de Phily for the suggestion!

[ad_1] Investigators with the Northern Tornadoes Project (NTP) from Western University say Thursday's storm across southwestern Ontario resulted in twisters touching down in Tecumseh and Windsor.Both occurred around 10:30 p.m. and lasted about 10 minutes causing destruction in the town and city.Collapsed barn from Lakeshore Road 103 is shown from ground level. (NTP)Data shows the Tecumseh tornado was the stronger of the two, assessed as an EF-1 with an estimated maximum wind speed of 145 km/h.It started in Tecumseh, running 14 kilometres down to Pleasant Park."There was additional damage to the southeast but further analysis is needed to know if it was related to this tornado," NTP said in an online statement.Map showing the locations of ground photos of damage from Tecumseh tornado. (NTP/Google)The twister continued toward the southeast from Tecumseh, into the Municipality of Lakeshore, and went past Highway 401 to the northeast of Pleasant Park."The track of surveyed damage did continue further southeast but damage became sporadic. Additional analysis is required to know if it is related to this tornado or something else, possibly a second tornado."Drone footage shows damage to Northway Avenue homes in Windsor, Ont. from an Aug. 24, 2023 tornado. (NTP)The confirmed tornado in Windsor was on the city's west side, according to NTP information, touching down around 10:30 p.m. Aug. 24.It touched down along a path nearly 12 kilometres long, running from Sandwich Town, south-southeast through south Windsor, into LaSalle."Investigators say they've concluded an EF-0 twister — with speeds of 125 km/h — moved rapidly through the area," according to an online statement from the NTP.Multiple trees uprooted along damage path of Windsor tornado on Aug. 24, 2023. (NTP)"Start time is based on radar, which showed an area of tight rotation along the entire damage path. Note that radar suggests the entire event took less than 10 minutes."Downbursts in Lambton County and Chatham-KentA downburst was also reported from Thursday's wild weather in the region on the northeast side of Chatham.Around 11 p.m. NTP data suggests numerous trees were uprooted and snapped, and had large branches broken. There was also roof damage to several homes.Drone footage shows damage to buildings and fields from a downburst in the Dresden area, on Marthaville Road, from Aug. 23, 2023. (NTP)Investigators say wind speeds were as high as 125 km/h when the downburst struck.Another downburst, but from the previous night's storm, Aug. 23, has also been confirmed in Lambton County.It was near Dresden, at the south end of Lambton County around 6:30 p.m. Damage is shown from a drone of Selkirk Street and Van Allen Avenue in Chatham, Ont., following a late night Aug. 24, downburst.

ENTP life

I need to be explicitly told why a rule is in place so I can discern whether it is important or not. So either you don't tell me, and the rule doesn't get followed or you tell me and it might get followed.

How loud is teleportation?

Here is something I’ve wondered about for a while: if you could teleport superpower-style, what happens to the medium you teleport from/into? The boring answer is, the volume you jump to replaces the volume you jump from: this could have weird side effects though. If you jumped underwater, you’d dump a bunch of water at your starting location. If you jumped underground, you’d live long enough to jump out; but there’d be a rock statue from where you first departed. The air could just disappear where you arrive, and new air could be created where you left, but that’s boring! It also requires a superpower or magic power that interacts in detail with the environment, unless, like, it’s always leaving behind inert nitrogen gas (which, again, would have weird effects).

Some stories posit that if you teleport into solid matter, you die, since the matter intersects your body. This is stupid. If that’s the case then teleporting into air (or water) would do the same thing, which would also kill you, because dumping dozens of liters of air and whatever microscopic objects happen to float in it into the human body instantaneously is going to cause all kinds of problems. Not least the pressure in your body is going to shoot up, bubbles are going to form in your blood, and your cells’ chemistry is going to freak out.

So the most logical version of this superpower to me has always seemed to be that you swiftly, but gradually, displace the surrounding medium as you arrive. Perhaps you are gradually inserted from the 4th dimension. Humans aren’t 4-dimensional, so if you were just dropped, you would still have to displace air instantly. But if you were inserted into the spot at an oblique angle (in the 4th dimension), then gradually rotated into place, or if instead some kind of superpowered or magical interface rapidly spread from the center of the teleportation spot to your skin, the air could simply be pushed aside.

If it’s too hard to be displaced by the force of your teleportation power, either the teleport fails or (perhaps) you die in a bizarre and grisly fashion. But if you’re displacing air... wouldn’t that make a noise? This has led me to today’s science problem, which is, how loud should teleportation be?

The average volume of a human (according to Google; I google all my constants ‘cause I’m lazy) is 62 L. Surface area is 1.92 m^2. Using the ideal gas law, we can figure out, for air compressed into a certain volume as a layer just above the skin, how much overpressure is produced. But this is unsatisfying, because we’re not positing our teleportation ability immediately and magically moves all the medium we displace to an arbitrarily thick layer around us. That would make sense, but most teleportation powers don’t use it, and it would lead to certain weird results--imagine compressing water, or some very rigid medium, and producing an extremely powerful shock wave! You could blow holes in walls by teleporting into them (well, if the rebound didn’t kill you).

Just how compressible is air? Wikipedia informs me an object moving quickly through a medium creates what is called ram pressure; if the direction of motion is perpendicular to the surface, it seems to be just P = ρu^2, where ρ is density of the medium and u is the velocity. The density of air at NTP is around 1.29 * 10^-3 kg/L. Sound waves create overpressure in air; and we are essentially creating a blast overpressure by rapidly displacing a specific volume of air. If we assume minimal energy loss from any instantaneous rebound of the body of the teleporting person, and that the amount of overpressure is close to the sound pressure as the disturbance propagates away from our body, we can get sudden, basically arbitrarily high pressures at the surface of our skin for arbitrary velocities of displacement. At 1 m/s, the overpressure is a tiny 0.001293 Pascals, so a sudden sharp noise about talking volume. At 100 m/s, it’s 12 Pa, which is 116 dB, just below the “threshold of discomfort” according to this table. So potentially this is quite a loud noise! In the spirit of Randall Munroe, though, let’s go higher.

At 1 km/s, we hit 156 dB, which Wikipedia says runs the risk of “instantaneous hearing loss,” which I can only assume means your eardrums will probably explode. At 100 km/s--probably close enough to “instant teleportation” as makes no difference--the sound produced in the immediate vicinity is a whopping 236 dB, which is far, far beyond the top of this Wikipedia table (remember, decibels are a logarithmic measure!). According to this page, this suggests a sound louder than the Tsar Bomba. If we want our teleportation power to work truly instantaneously, or as close to it as possible, this would involve the teleportation interface moving at the speed of light. That would produce an immediate overpressure wave clocking in at 375 decibels. Krakatoa, according to the previous source, was only 310 dB (I assume they mean “as close to the source as you could theoretically be). This is many orders of magnitude beyond that. Let’s be realistic; at this point relativistic effects apply, so who knows what the actual result would be, but we would probably be better off measuring it on the Richter scale (or possibly Torino). You’d better use your teleport effectively; all that is left of you is likely to be a fine mist.

I am dissatisfied with assuming we could produce almost arbitrarily loud results in this way, because it seems unreasonable that displacing such small volumes of air could have such stupendous results. But momentum must be taken into account, I suppose; if you’re pushing air molecules at 100 km/s, you’re depositing quite a large sum of energy into the surrounding medium. More importantly, though, physically consistent, near-instantaneous teleportation is not a stealthy power! At the lower end of the estimate, it’s probably not loud enough to draw attention on a busy street, but you’re definitely gonna notice if somebody appears behind you. And people will notice when you leave: a similar noise will occur when you leave behind a person-shaped hole in the air, although the loudness will max out much lower (my naive guess is about 194 dB, the loudness of a Saturn V rocket launch; but since air is moving into a vacuum here, I am even more unsure of this number).

I encourage corrections from people better at math or with more relevant knowledge; what I tried to find is a table or graph relating overpressure at the point of an explosion to loudness recorded from a specific distance away, but I couldn’t find anything. But if anybody has some explosives, spare barometers, and a big empty field going spare, do let me know, that sounds like a fun weekend project.
