Your brain on shrooms — how psilocybin resets neural networks

Taking psilocybin, the hallucinogenic compound found in magic mushrooms, temporarily resets entire networks of neurons in the brain that are responsible for controlling a person’s sense of time and self, finds a study that repeatedly imaged the brains of seven volunteers before, during and after they took a massive dose of the drug.

The findings, published in Nature on 17 July1, could offer insights into why the compound might have a therapeutic effect on some neurological conditions.

Researchers “saw such massive changes induced by psilocybin” that some study participants’ brain-network patterns resembled those of a different person entirely, says Shan Siddiqi, a psychiatric neuroscientist at Harvard School of Medicine in Boston, Massachusetts. “I’ve never seen an effect this strong.”

Most of these changes lasted for a few hours, but one key link between different parts of the brain remained disrupted for weeks.

NASA RADAR DATA CONFIRMS EXISTENCE OF SUBSURFACE “TUNNEL” NEAR FAMOUS APOLLO-ERA LUNAR LANDING SITE

For the first time, scientists have confirmed the existence of an underground tunnel-like feature near the landing site of the first crewed mission to the Moon. The discovery concludes almost half a century of speculation involving the suspected existence of caves below the lunar surface.

On July 20, 1969, astronauts Neil Armstrong and Buzz Aldrin became the first humans to set foot on the lunar surface after making a soft landing in the Apollo 11 Lunar Module on the mare plain of the Moon’s famous Mare Tranquillitatis, Latin for “Sea of Tranquility.”

Now, according to the findings of an international team of researchers led by the University of Trento in Italy, the existence of a subsurface tunnel-like lava tube cave beneath the Mare Plain has been confirmed.

A new study published in the journal Nature Astronomy revealed the discovery, which relied on data obtained with NASA’s Lunar Reconnaissance Orbiter (LRO).

The discovery of the tunnel-like feature has been called a significant milestone toward understanding the Moon’s various geological components more fully. It also offers a potential shelter area that could be used by astronauts during future crewed missions.

Lorenzo Bruzzone, a professor at the University of Trento, said the existence of such underground features had long been suspected, although the team’s discovery is the first confirmation that they exist.

“These caves have been theorized for over 50 years,” Bruzzone said in a statement, “but it is the first time ever that we have demonstrated their existence.”

Data originally obtained in 2010 by the Miniature Radio-Frequency (Mini-RF) instrument aboard the LRO, which included radar reflections from a pit discovered in the Mare Tranquilitatis, were reexamined by the research team.

“Thanks to the analysis of the data, we were able to create a model of a portion of the conduit,” said Leonardo Carrer, a researcher at the University of Trento involved with the new findings.

“The most likely explanation for our observations is an empty lava tube,” Carrer said.

Given the demanding environment on the surface of the Moon, where temperatures can reach as much as 127°C on its illuminated side while dropping to frigid lows nearing -173°C on the unilluminated side, lava tube caves could be ideal locations for astronauts to use as shelters on the Moon.

In addition to being ideal environments for subsurface shelters, such an underground tunnel-like feature could also provide a degree of shielding from cosmic and solar radiation that bombards the lunar surface, which can be up to 150 times more powerful there than on Earth.

PHOTON ENERGY SYSTEM THAT GENERATES 60 TIMES MORE POWER THAN SOLAR PANELS COULD POWER AN ELECTRIC CAR WITHOUT A BATTERY

New York-based tech company Wavja says the third generation of its proprietary Photon Energy System (PES), which employs tiny spheres to collect photonic energy, generates over 60 times the output of similarly sized traditional solar panels. According to a new video released by the company, the next generation of the PES could soon be powerful enough to run an electric car without a battery.

The company says its system can also capture light energy from artificial sources, including LED lighting, and convert it to usable electricity, offering both indoor and outdoor applications.

“Our system generates remarkable luminosity by utilizing multiple layers of cutting-edge materials and specialized spheres,” explains Shereen Chen, co-founder and executive director of Wavja USA, in the recently posted video. “This luminosity is then seamlessly converted to electricity using our proprietary technology.”

“It revolutionizes how we harvest sunlight,” Chen adds.

BIZARRE TACHYONS THAT MAY BE ABLE TO SEND DATA BACK IN TIME COULD BE RECONCILED WITH SPECIAL RELATIVITY

Tachyons, a mysterious variety of hypothetical particles capable of exceeding light speed, could play a more significant role in our understanding of the universe and its causal structure than scientists previously realized.

Not only have tachyons been revealed to be potentially compatible with Einstein’s special theory of relativity, but now, according to an international collaboration of physicists from the University of Warsaw and the University of Oxford, these curious particles could also help shed light on remaining questions regarding our understanding of the quantum world.

EXCEEDING THE UNIVERSAL SPEED LIMIT

Tachyons, which derive their name from the Greek word tachýs, meaning fast or quick, are theorized to exist under conditions where their minimum speed would be the speed of light. This effectively means that they should only be capable of traveling at velocities that exceed this universally recognized speed limit.

Ordinary particles, by comparison, move at subluminal or slower than light speeds. As Einstein’s theory of relativity dictates, the universal laws of physics prevent anything from being capable of accelerating to the speed of light from a slower speed. The same isn’t necessarily true for tachyons, though, since they are theorized to be born at speeds that already exceed light. Hence, the opposite would seem to be the case for these unusual particles, which hypothetically should be incapable of slowing down to light speed or slower speeds.

The idea of such superluminal particles has its origins in theoretical studies conducted back in the 1960s by physicist Gerald Feinberg. Although no experimental evidence has ever confirmed their existence, a theoretical framework for how these proposed particles might come to be has been developed over the decades, occasionally resulting in some rather strange paradoxes.

Among these is a curiosity that arises from their superluminal travel speeds, which indicates that tachyons may effectively be capable of sending information backward in time, giving rise to bizarre conditions under which cause and effect could theoretically become reversed.

However, new research is revealing that despite the implications of their existence, these bizarre hypothetical particles may be compatible with the special theory of relativity and could also help offer physicists significant new insights into quantum theory.

The new findings could potentially also upend long-held notions about the unlikelihood of superluminal particles, suggesting that tachyons might even play a crucial role in the formation of matter.

‘Amazing’ new technology set to transform the search for alien life

It has produced one of the most consistent sets of negative results in the history of science. For more than 60 years, researchers have tried to find a single convincing piece of evidence to support the idea that we share the universe with other intelligent beings. Despite these decades of effort, they have failed to make contact of any kind.

But the hunt for alien civilisations may be entering a new era, researchers believe. Scientists with Breakthrough Listen, the world’s largest scientific research programme dedicated to finding alien civilisations, say a host of technological developments are about to transform the search for intelligent life in the cosmos.

These innovations will be outlined at the group’s annual conference, which is to be held in the UK for the first time, in Oxford, this week. Several hundred scientists, from astronomers to zoologists, are expected to attend.

Astronomer Steve Croft, a project scientist with Breakthrough Listen, said: “There are amazing technologies that are under development, such as the construction of huge new telescopes in Chile, Africa and Australia, as well as developments in AI. They are going to transform how we look for alien civilisations.”

Researchers demonstrate how to build ‘time-traveling’ quantum sensors

The idea of time travel has dazzled sci-fi enthusiasts for years. Science tells us that traveling to the future is technically feasible, at least if you’re willing to go near the speed of light, but going back in time is a no-go. But what if scientists could leverage the advantages of quantum physics to uncover data about complex systems that happened in the past?

New research indicates that this premise may not be that far-fetched. In a paper published June 27, 2024, in Physical Review Letters, Kater Murch, the Charles M. Hohenberg Professor of Physics and Director of the Center for Quantum Leaps at Washington University in St. Louis, and colleagues Nicole Yunger Halpern at NIST and David Arvidsson-Shukur at the University of Cambridge demonstrate a new type of quantum sensor that leverages quantum entanglement to make time-traveling detectors.

Murch describes this concept as analogous to being able to send a telescope back in time to capture a shooting star that you saw out of the corner of your eye. In the everyday world, this idea is a non-starter. But in the mysterious and enigmatic land of quantum physics, there may be a way to circumvent the rules. This is thanks to a property of entangled quantum sensors that Murch refers to as “hindsight.”

The process begins with entanglement of two quantum particles in a quantum singlet state—in other words, two qubits with opposite spin—so that no matter what direction you consider, the spins point in opposing directions. From there, one of the qubits—the “probe,” as Murch calls it—is subjected to a magnetic field that causes it to rotate.

Scientists successfully create a time crystal made of giant atoms

A crystal is an arrangement of atoms that repeats itself in space, in regular intervals: At every point, the crystal looks exactly the same. In 2012, Nobel Prize winner Frank Wilczek raised the question: Could there also be a time crystal—an object that repeats itself not in space but in time? And could it be possible that a periodic rhythm emerges, even though no specific rhythm is imposed on the system and the interaction between the particles is completely independent of time?

For years, Frank Wilczek’s idea has caused much controversy. Some considered time crystals to be impossible in principle, while others tried to find loopholes and realize time crystals under certain special conditions.

Now, a particularly spectacular kind of time crystal has successfully been created at Tsinghua University in China, with the support from TU Wien in Austria.

The team used laser light and special types of atoms, namely Rydberg atoms, with a diameter that is several hundred times larger than normal. The results have been published in the journal Nature Physics.

Federal Science Agency Begins Selling ‘Most Carefully Quantified Cannabis Ever Sold’—For $174 A Gram

As part of an ongoing effort to help testing laboratories more reliably determine the potency and purity of marijuana and hemp, a federal science agency has begun selling packages of what it’s calling “some of the most carefully quantified cannabis ever sold.”

Picking up 4.5 grams of the stuff will cost $783, or $174 a gram—far more expensive than the cannabis that’s commercially available in states across the country.

The hemp product, sold by the National Institute of Standards and Technology (NIST), isn’t intended for consumption. Rather, it’s a tool to help labs calibrate their analyses of cannabinoids and toxic elements in both hemp and higher-THC marijuana.

“To ensure that their measurement methods are working properly, labs can analyze a bit of this material,” NIST said in a press release about its new offering, known as hemp plant reference material, or RM 8210. “If their numbers match those from NIST to within an accepted margin of error, all is well. If not, they’ll know they need to recalibrate their instruments or otherwise troubleshoot their methods.”

For just under $800, a lab receives three 1.5-gram sample packages of hemp. The samples are carefully measured by NIST for a variety of chemical components, including eight individual cannabinoids such as CBD and delta-9 THC, as well as 13 different toxic elements, like arsenic and heavy metals.

“Although this reference material is composed of hemp,” NIST said in its release, “labs can use it to validate their measurements of both hemp and marijuana, and it will help companies in the fast-growing cannabis industry and state regulators ensure that cannabis products are safe and accurately labeled.”

NIST biologist Colleen Bryan, who was part of the team the developed the reference material, said that consumers ought to be able to rely on what’s printed on product labels.

“If you buy a product that claims to have 25 milligrams of CBD per dose, you should be able to trust that number,” Bryan said, noting that some people use cannabis for medical reasons and may be particularly concerned about safety. “This reference material will help ensure that the cannabis they buy does not contain unsafe levels of toxic elements.”

NASA spots unexpected X-shaped structures in Earth’s upper atmosphere — and scientists are struggling to explain them

A NASA satellite has spotted unexpected X- and C-shaped structures in Earth’s ionosphere, the layer of electrified gas in the planet’s atmosphere that allows radio signals to travel over long distances.

The ionosphere is an electrified region of Earth’s atmosphere that exists because radiation from the sun strikes the atmosphere. Its density increases during the day as its molecules become electrically charged. That’s because sunlight causes electrons to break off of atoms and molecules, creating plasma that enables radio signals to travel over long distances. The ionosphere’s density then falls at night — and that’s where GOLD comes in.

NASA’s Global-scale Observations of the Limb and Disk (GOLD) mission is a geostationary satellite that has been measuring densities and temperatures in Earth’s ionosphere since its launch in October 2018. From its geostationary orbit above the western hemisphere, GOLD was recently studying two dense crests of particles in the ionosphere, located north and south of the equator. As night falls, low-density bubbles appear within these crests that can interfere with radio and GPS signals. However, it’s not just the wax and wane of sunshine that affects the ionosphere — the atmospheric layer is also sensitive to solar storms and huge volcanic eruptions, after which the crests can merge to form an X shape.

In its new observations, GOLD found some of these familiar X shapes in the ionosphere — even though there weren’t any kinds of solar or volcanic disturbances to create them.

“Earlier reports of merging were only during geomagnetically disturbed conditions,” Fazlul Laskar, a research scientist at the University of Colorado’s Laboratory for Atmospheric and Space Physics (LASP), said in a statement. Laskar is the lead author of a paper published in April in the Journal of Geophysical Research: Space Physics that described these unexpected observations.

From Fauci to Levine, feds covertly bend science to politics on COVID origin, gender confusion

Federal pressure on private parties to squelch challenges to Biden administration narratives, tacitly tolerated by the Supreme Court in a decision last month making it harder for social media users to sue public officials, goes beyond COVID-19, elections and Hunter Biden’s laptop. 

It also includes how to treat children with so-called “gender confusion,” as revealed by legal discovery in a lawsuit challenging Alabama’s ban on puberty blockers and cross-sex hormones for those under 19 – what supporters call gender-affirming care, which also includes surgical removal of healthy breasts and genitals.

A YouGov poll last month found most Americans agree with presumptive Republican presidential nominee Donald Trump’s position on the issue – banning “hormonal or surgical treatment for transgender minors” – while fewer than one-third back President Biden’s opposition.

Unlike the murky role played by then-National Institutes of Allergy and Infectious Diseases Director Dr. Anthony Fauci in virus researchers suddenly changing their minds about SARS-CoV-2’s origin, Assistant Secretary for Health Rachel Levine’s demands heavily influenced a transgender health group’s last-minute decision to lower its standards for minors.

Also influential was the American Academy of Pediatrics’ threat to the World Professional Association for Transgender Health to oppose the eighth version of WPATH’s Standards of Care, which are widely relied upon globally by gender clinics, healthcare providers and insurers, if the final version of SOC 8 kept the age minimums in the draft.

The two organizations closely collaborate, according to emails between their leadership obtained by The Daily Caller News Foundation through a public records request to West Virginia University, which employs a WPATH U.S. affiliate board member and AAP Committee on State Government Affairs member.

While scientists on the Feb. 1, 2020 conference call with Fauci had a potential personal interest in discrediting the COVID lab-leak theory – Fauci’s discretion over NIAID research grants – communications between staff for Levine and WPATH don’t suggest the latter feared financial retribution from Levine.
