A mobile unit containing three floatation tanks is en route to Maui, Hawaii, in response to the mental health crisis ignited by the catastrophic wildfires, which were the deadliest in U.S. history. Floatation therapy, often found in upscale spas, is emerging as a viable treatment for anxiety and post-traumatic stress disorder (PTSD). If this initiative proves successful, similar units could be deployed in disaster-stricken areas worldwide.

In August 2023, devastating wildfires erupted in Maui, resulting in the tragic loss of 102 lives and destroying thousands of homes and businesses. Following these events, the risk of depression and anxiety has surged by over 50%, highlighting the urgent need for PTSD interventions.

“Maui lacks the infrastructure to manage a mental health crisis of this scale,” states Justin Feinstein, a clinical neuropsychologist and founder of a nonprofit organization, the Float Research Collective. “People are resorting to self-medication. Alcohol consumption is rising, and rates of suicide and PTSD are increasing.”

On May 2nd, Feinstein announced the Embodied Mind Summit in Los Angeles, where free floatation therapy sessions will be provided for first responders and wildfire survivors, while simultaneously gathering long-term data on float therapy’s efficacy for mental health treatment.

Float therapy, also referred to as environmental stimulus reduction therapy, entails lying in a shallow pool saturated with Epsom salt, allowing the body to float effortlessly. The pool’s water and the surrounding air are maintained at body temperature, with earplugs minimizing noise and the lights turned off to create an environment free of sensory distractions.

This innovative tank design originated with neuroscientists in the 1950s to explore whether the brain would deactivate without external stimulation. Surprisingly, participants remained conscious but reported heightened relaxation.

Feinstein has dedicated more than a decade to researching the treatments and the mental and physical effects of float therapy. His studies indicate significant reductions in anxiety for both healthy individuals and those with various mental health disorders, such as depression and PTSD. Feinstein notes that the effects can be almost as impactful as benzodiazepines, a common sedative.

While the exact mechanisms remain unclear, floatation therapy appears to alleviate external sensory input and reduce bodily movement, thereby inducing a state of tranquility in both the body and mind. Research indicates that shortly after floating, breathing and heart rates decrease, along with blood pressure, and brain activity shifts from self-referential thoughts and emotional processing to states resembling restorative sleep.

Residing in Maui since 2020, Feinstein collaborated with the UK-based company Floataway to develop a cost-effective, modular float pod that can be assembled rapidly in various locations, unlike traditional tanks. The Maui Calm Project aims to introduce these tanks in the region and begin data collection this summer. If successful, the initiative seeks to establish a fleet of portable tanks for deployment in disaster areas to combat PTSD.

According to Sarah Garfinkel, a professor at University College London studying the physical basis of PTSD, prioritizing body-calming techniques represents a crucial evolution in the treatment of this condition. “Hyperarousal is a core feature of PTSD, leading to heightened reactive physiological responses,” she explains. “It seems that floating could offer a sense of internal safety, which may transform our understanding and management of PTSD. I’m eager to see the results of this research.”

New Study Reveals Ancient Earth Experienced Repeated Melting Events During Catastrophic Ice Ages

Posted on by

During the Neoproterozoic Era (1 billion to 538.8 million years ago), Earth underwent dramatic climate fluctuations, notably the Sturtian Ice Age, where ice is believed to have enveloped the planet. Understanding the geological record and the survival of life during this pivotal event has remained a significant challenge. Geochronological studies indicate that the Sturtian Ice Age persisted for an astonishing 56 million years, far exceeding predictions made by conventional climate models. A recent study from Harvard University proposes that Earth may have experienced cycles of ice-covered and ice-free states during the Sturtian period.

“The global glaciation that occurred near the advent of animal life, known as the Neoproterozoic Snowball Earth event, represents one of the most severe climate transformations in Earth’s history and likely had profound effects on biological evolution,” stated Charlotte Minsky, a Harvard graduate student, along with her research team.

“However, the causes, severity, and ecological impacts of these glaciations continue to be the subject of intense debate.”

Employing a coupled model of ancient climate systems and the global carbon cycle, researchers propose that Earth was not trapped in a singular, incessant snowball state.

Their simulations indicate that extensive weathering of basalt in the Franklin Igneous Province, a significant volcanic area in northern Canada that likely erupted prior to the Sturtian Ice Age, dramatically reduced atmospheric carbon dioxide levels, leading to multiple global ice ages.

As volcanic activity and other processes gradually rebuilt atmospheric carbon dioxide, global temperatures rose, ice melted, and previously covered basalt regions were exposed once more.

This renewed decomposition through weathering replenished carbon dioxide, triggering another snowball cycle.

The authors contend that this recurring cycle of freezing and thawing driven by carbon dioxide could sustain glacial and interglacial variations for tens of millions of years.

The mechanisms revealed in this study address several longstanding discrepancies, particularly the duration of the Sturtian Ice Age, which was previously challenging to reconcile with established climate models.

This research aligns with sedimentation patterns from that era, elucidating how atmospheric oxygen levels could remain stable amidst extreme climatic shifts.

Moreover, frequent returns to warmer, ice-free states may have been critical in preventing a total collapse of atmospheric oxygen.

“This discovery may elucidate how aerobic life continued to thrive throughout such severe intervals,” Minsky noted.

Astronomers Observe Dramatic Aftermath of Catastrophic Planetary Collision

The captivating flickering of the young F-type star, Gaia-20ehk, along with the expanding dust cloud encircling it, indicates a dramatic planetary collision unfolding in real time. This event provides a unique opportunity to observe the violent processes involved in the formation of nascent planetary systems.

Located approximately 11,000 light-years from Earth in the constellation Leo, Gaia20ehk is a stable “main sequence” star, typically known for its steady and predictable luminosity. However, since 2016, this star has exhibited violent flickering.

“Initially, the star’s light output was consistent, but it has since dropped by around 3 degrees,” remarked Anastasios (Andy) Tzanidakis, a doctoral candidate at the University of Washington. “By 2021, the situation escalated dramatically.”

“Such behavior is unexpected for stars like our Sun. When we observed this, we thought, ‘What could be happening here?'”

The flickering of Gaia20ehk is not due to the star itself. Instead, it is caused by a cloud of rocks and dust obstructing the light as it orbits the system.

The astounding source of this debris appears to be a catastrophic planetary collision.

“It’s remarkable that multiple telescopes captured this impact in real time,” Tzanidakis stated.

“There are only a handful of documented planetary collisions, and none possess as many parallels to the impacts that formed Earth and the Moon.”

“Observing similar events in other parts of the galaxy could significantly enhance our understanding of our planet’s formation.”

Additionally, evidence suggests this impact may closely resemble the one that created the Earth and Moon approximately 4.5 billion years ago.

This dust cloud orbits Gaia20ehk at about 1 astronomical unit, the same distance from its star as Earth is from the Sun.

At this distance, materials could eventually cool and solidify into structures akin to the Earth-Moon system.

“How rare was the event that shaped the Earth and Moon? This inquiry is essential to the field of astrobiology,” commented James Davenport, a professor at the University of Washington.

“The Moon seems to play a crucial role in making Earth a habitable place, shielding it from some asteroids, influencing ocean tides and weather patterns, and potentially even facilitating geological activity.”

“Currently, the prevalence of these dynamics remains uncertain, but as we observe more collisions, we will gain clearer insights.”

The team’s research paper will be published in today’s Astrophysical Journal Letters.

Physicist Issues Stern Warning on ‘Catastrophic’ Effects of Science Funding Cuts in the UK

CERN's Large Hadron Collider impacted by funding cuts

Impact of UK Spending Cuts on CERN’s Large Hadron Collider

Traczyk, Piotr/CERN 2021-2024

British scientists are raising alarms over the potential “catastrophic” effects of impending budget cuts on physics research. With public funding agencies facing an average 30% reduction, groups are preparing for possible cuts of up to 60%.

Many research teams may lose their funding entirely, leading to a decline in research jobs and a potential withdrawal from significant international projects, including CERN, the prestigious particle physics laboratory located near Geneva, Switzerland.

UK Research and Innovation (UKRI), the public body responsible for funding science and business, has delineated a £38.6 billion budget over the next four years. Although UKRI claims this figure does not account for inflation, it suggests a marginal increase. However, physics researchers predict substantial cuts are imminent.

UKRI’s budgetary plans aim to bolster scientific research while benefiting the national economy. As CEO Ian Chapman asserted in a February 5 press briefing, the organization must prioritize commercialization and make hard choices for the greatest national impact.

UKRI allocates grants through nine councils, including the Science and Technology Facilities Council (STFC) which specializes in particle physics, nuclear physics, and astronomy, covering financial commitments to CERN and the European Space Agency. STFC is anticipated to bear the majority of the cuts, with reports indicating a staggering £162 million reduction.

Grant recipients of STFC have been advised to brace for an overall funding reduction of 30%. Additionally, they have been asked to devise budget alternatives anticipating 20%, 40%, and 60% cuts. The Institute of Physics (IOP) deemed this news “a devastating blow” to British physics foundations.

IOP President-elect Paul Howarth warned that these cuts would undermine “our understanding of space and humanity’s progress.” He emphasized that cutting UK funding would diminish the nation’s experimental capacity, stifling innovation and economic growth. “We implore the Government to reconsider its funding strategies,” he stated.

Michelle Doherty, STFC’s executive chairman, acknowledged the organization’s overly ambitious goals. “We are stretching our resources too thinly and are facing tough years ahead,” she remarked. “Our current budget restricts us from achieving all our objectives.”

During her briefing, Doherty highlighted the end of international collaboration in particle physics due to financial constraints, a reality that partners abroad are also grappling with.

John Ellis, a professor at King’s College London, cautioned that job reductions would damage the UK’s standing among international research collaborators. “Such actions tarnish the UK’s reputation as a dependable partner,” he noted.

Projects like the ATLAS experiment at the Large Hadron Collider (LHC), instrumental in discovering the Higgs boson, are at risk. Funding was allocated for upgrades during the experimental shutdown. “We face uncertainty about future solutions,” Ellis lamented.

Another LHC initiative, LHCb, which examines the matter-antimatter disparity, may also see its budget eliminated, jeopardizing essential upgrades. Reports suggest the UKRI’s funding for the U.S.-led electron-ion collider in New York is also at risk. UKRI has not clarified the status of these projects when approached for comment by New Scientist.

Ellis warned that significant cuts to physics research could hamper the UK’s future by eliminating opportunities for postdocs and junior researchers. “This isn’t a minor setback; it risks stifling a generation of young scientists,” he argued.

Jim Al Khalili, a professor at the University of Surrey, echoed these concerns, pointing out the potential decline in skill and knowledge necessary for the country’s nuclear industry and wider research initiatives. “These proposed budget reductions would devastate our communities,” he asserted.

Alicia Grated of the Science and Engineering Campaign, representing UK research institutions, noted that miscommunication regarding the cuts has resulted in confusion and uncertainty. “Clarity is crucial, regardless of the reasons behind the decision to rescind STFC funding,” she emphasized. “Any decrease in support for STFC’s resources could threaten a fundamental segment of our research ecosystem.”

Likelihood of Catastrophic Asteroid Impact Rises Temporarily in 2025

Posted on by

In 2025, the threat of a disastrous asteroid impact momentarily heightened when astronomers detected a building-sized asteroid on a collision course with Earth.

Known as 2024 YR4, this asteroid was initially identified by astronomers in late December 2024, with estimates placing its size between 40 and 90 meters. Any potential trajectory through our solar system would intersect a narrow zone that includes Earth, leading astronomers to initially assess a 1 in 83 probability of collision in 2032.

As they monitored the asteroid’s orbit more closely in early 2025, the likelihood of an impact was updated to a concerning 1 in 32 by February.

If it had impacted close to an urban area, the consequences would have been devastating, equivalent to several megatons of TNT. The asteroid was temporarily classified as a 3 on the Turin scale, where 0 means no threat and 10 signifies a global catastrophe. This raised alarms among several United Nations agencies, resulting in coordinated efforts for a global telescope campaign and discussions on the necessity of an asteroid deflection mission.

During this period, global space agencies convened regularly to share observations and enhance understanding of the asteroid. “2024 YR4 proved to be a significant learning experience for us,” stated Richard Moisle from the European Space Agency (ESA). “This served as crucial training to enhance our capabilities related to asteroid detection and understanding the overarching challenges.”

By February 20, astronomers had refined the trajectory of 2024 YR4, effectively removing Earth from the asteroid’s predicted path, and ESA subsequently reduced the collision risk to 1 in 625, or 0.16 percent. Weeks later, both NASA and ESA confirmed that there was no longer any risk of collision. “They are not considered a threat to our planet,” affirmed Moisle.

Nonetheless, astronomers still acknowledge a minor risk of a lunar impact, estimated at about 4% for 2032. “Should we hit the moon, it would provide a unique opportunity to observe the impact process from a safe distance,” commented Gareth Collins from Imperial College London.

Researchers are now assessing the potential ramifications of an asteroid impacting the moon, including the risk of debris cascading toward Earth. They are also exploring the feasibility of a deflection mission and strategizing on how to effectively dispatch a small satellite to an asteroid in an attempt to detonate it with a nuclear device. “We must tread carefully to ensure that a moon impact does not unintentionally lead to an Earth impact,” Rang Moisle.

The present 4 percent chance of a lunar collision is not sufficiently alarming to compel global space agencies to initiate a formal mission. This probability is unlikely to shift soon, as 2024 YR4 is currently obscured by the Sun and won’t be visible until 2028. However, due to its unique positioning in Earth’s orbit, there will be a rare opportunity to observe it with the James Webb Space Telescope in February 2026. Moisle indicated that since planning an asteroid mission can take years, data from these observations will represent the last realistic chance to determine whether a mission to visit or deflect the asteroid is warranted.

US Withdrawal of Support for CMB-S4 Telescope is Catastrophic

Posted on by

South Pole telescope. CMB-S4 was meant to explore temperature and polarization changes in microwave light across vast areas of the sky.

Brad Benson, University of Chicago Fermilab

In the words of Robert Frost from The Road Not Taken, “Two roads diverged in a yellow wood / And sorry I could not travel both.”

This sentiment resonates as I reflect on the U.S. government’s July 9 announcement: CMB-S4 projects will no longer receive support. CMB-S4 (Cosmic Microwave Background Stage 4) was set to be the next groundbreaking multicontinental telescope system, promising unparalleled insights into the oldest light traversing the universe.

Initially, the universe was a turbulent mix of dense particles and plasma, so thick that photons (light particles) could scarcely move without colliding with something. This primordial environment was also extremely hot, hindering the formation of atoms. It wasn’t until cosmic inflation—a rapid expansion of spacetime lasting an imperceptibly short period—that temperatures fell sufficiently to allow the first hydrogen atoms to form, providing photons the freedom to zip across space.

Sixty-one years ago, we discovered the existence of these photons, known as cosmic microwave background radiation (CMB). What began as mere background noise in radio signals has been recognized as a link to the early universe, leading us to meticulously analyze the wavelengths, intensities, and variations of these photons.

The CMB offers a trove of information regarding the origins of all matter we observe, including stars that later create gold through supernovae. By surveying the entire sky for changes in photon temperatures, we can identify minute fluctuations in temperature. While their positions appear random, the magnitude of these variations is consistent across the board.

Our prevailing theory posits that these fluctuations arise from tiny quantum variations in matter density at the time the photons were released. Greater concentrations of matter served as the seeds for gas accumulation, which ultimately merged into protostars, leading to the formation of stars and galaxies. Thus, these CMB fluctuations mark our cosmic genesis.

“
The withdrawal from this project signifies a reckless retreat by the U.S. from global scientific cooperation.
“

One of the most significant measurements we’ve derived from the CMB is how its temperature fluctuations correlate with various physical scales. Understanding the distances over which particular phenomena manifest allows us to analyze the variation’s origins—whether from larger or smaller scales. Essentially, different epochs in cosmological history are imprinted within the CMB.

For instance, we can “detect” when the universe became transparent to matter and when hydrogen first formed, an epoch referred to as recombination. Although these events are beyond our visual perception, we can gauge the presence of dark matter and dark energy based on their influence on the CMB.

CMB-S4 aimed to advance our understanding of the lessons the CMB has to offer. An important objective was to seek evidence of primordial gravitational waves, ripples in spacetime associated with cosmic inflation. Although different inflationary models propose plausible physical descriptions of our universe, specific details remain elusive. The signatures of gravitational waves on the CMB may provide the most effective means of distinguishing among these models.

The cessation of government backing for CMB-S4 is akin to jamming a bike’s wheel, abruptly halting our exploration of the cosmos. The repercussions will be felt globally. Historically, the U.S. has made significant investments in cosmological science, which attracts students internationally to its educational institutions. U.S.-sourced experimental data typically serves as a critical global resource. The retreat from the project, which seemed likely under the former administration, is now part of a broader trend of the U.S. distancing itself from global collaboration.

Frost concludes his poem by reflecting on the implications of his chosen path. It is indeed regrettable that the United States has opted not to explore the less traveled road in scientific pursuits. It undoubtedly makes an impact, but unfortunately, not for the better.

Remarkable Discovery: Two Fossils of Young Individuals Tragically Lost to a Catastrophic Storm in Germany

Posted on by
Reply

Paleontologists from the University of Leicester studied two immature fossilized skeletal remains of Pterodactylus antiquus, individuals whose wings were damaged and were discovered in Solnhofen limestone, southern Germany. Their findings reveal that these creatures were sadly victims of a powerful Jurassic storm, which created the perfect conditions for fossilization, leading to the preservation of hundreds of similar specimens.

“Dating back 153-148 million years, the Jurassic Solnhofen limestone deposits in Bavaria, southern Germany, are renowned for their remarkably preserved fossils, including many examples of various pterosaurs, flying reptiles from the Mesozoic era.”

“A puzzling aspect of this site is that while Solnhofen is home to hundreds of pterosaur fossils, almost all are small, immature specimens that are remarkably intact.”

“In stark contrast, larger adult pterosaurs are infrequently found and typically represented by isolated fragments, such as skulls or limbs.”

“This trend contradicts expectations, as larger, more resilient animals should theoretically have a greater chance of fossilization than fragile juveniles.”

In their latest study, the researchers examined the fossilized remains of two immature pterosaurs from the Solnhofen limestone.

These individuals belong to Pterodactylus antiquus, a species that inhabited Germany during the late Jurassic period.

With a wingspan of under 20 cm (8 inches), these hatchlings represent the smallest known pterosaurs.

Both specimens exhibit identical injuries: a clean, sloping fracture in the humerus.

One specimen’s left wing and another’s right wing appear broken in a manner consistent with a strong twist, likely caused by a sudden gust of wind rather than impact with a hard object.

The unfortunate pterosaur was likely submerged beneath the lagoon’s surface, overwhelmed by storm waves, and swiftly sank to the seabed, where it was quickly buried by a fine layer of mud stirred up by the tempest.

This rapid entombment facilitated the exceptional preservation observed in the fossils.

It’s reminiscent of a scene only days or weeks after the animals’ demise, with preservation so remarkable that while no significant skeletal trauma is evident, many other small, very young pterosaurs are found within the Solnhofen limestone.

These juvenile pterosaurs, unable to withstand the storm’s ferocity, were also drawn into the lagoon.

This discovery clarifies why smaller fossils are so well preserved—due to the direct aftermath of the storm, which was a common cause of death for pterosaurs in the region.

“For centuries, scientists believed the Solnhofen lagoon ecosystem was primarily composed of small pterosaurs,” stated Dr. Smith.

“However, we now recognize that this perspective was quite skewed; many of these pterosaurs were not lagoon dwellers.”

“Most were likely immature individuals that lived on nearby islands, inadvertently caught in a powerful storm.”

A study detailing these findings was published today in the journal Current Biology.
