Doug Whitney, an American man with a genetic predisposition for early-onset Alzheimer’s disease, has successfully avoided the illness, possibly due to accidental heat exposure while working as a mechanic in a ship’s engine room. This incident aligns with emerging research indicating that heat therapy may mitigate Alzheimer’s symptoms.

Whitney’s family carries a genetic variant known as Presenilin 2, inherited from ancestors in a Volga German village dating back to the 18th century. Carriers of this variant typically experience Alzheimer’s symptoms in their late 40s or early 50s.

“My family has been devastated by this disease,” Whitney stated in a press statement. “My mother had 13 siblings, and 10 of them died before they were 60. It was an epidemic.”

Despite having the same mutation, Whitney reached his late 70s without significant memory loss or Alzheimer’s symptoms, making him the only known carrier to escape the condition well beyond the expected onset age.

Jeffrey Kane, a doctor at the French National Center for Scientific Research, became intrigued by Whitney’s case during a conference. He discussed it with Randall Bateman, who has researched Whitney for many years.

At the conference, Kane shared research on hyperthermia’s positive effects on mouse brains. A Finnish study revealed that frequent sauna users are 65% less likely to develop Alzheimer’s disease. Kane and colleague Emmanuel Planel from Université Laval aimed to examine the mechanisms behind this observation.

The results were compelling, especially since Bateman noted Whitney’s extensive work in excessively hot engine rooms of naval vessels for over two decades, beginning at age 18. This led to encouragement from Kane and Planel to further investigate.

In the ship’s engine room, temperatures could soar to 50°C (122°F), and Whitney frequently spent hours inside, sometimes needing to cool down with hoses to prevent overheating.

This prolonged heat exposure likely led to Whitney exhibiting elevated levels of heat shock proteins in his cerebrospinal fluid, which are produced to repair and refold damaged proteins in response to heat.

The increased heat shock proteins might have shielded Whitney from Alzheimer’s development by regulating an essential brain protein called tau, according to Canet. In Alzheimer’s patients, tau proteins misfold and aggregate, correlating with cognitive decline. Imaging studies show that Whitney’s brain contains minimal abnormal tau, explaining his symptom absence. Conversely, his brain is filled with misfolded amyloid proteins, typical in Alzheimer’s, yet symptoms remain unpredictable.

Whitney prepares for a PET scan in March 2025 as part of the annual Alzheimer’s Research Testing Program at Washington University in St. Louis, Missouri.

Supporting their findings, Kane and Planel discovered that placing mice in a mini sauna helped maintain the tau protein’s structure and boosted its clearance from the brain. Likewise, tau clearance was found to be enhanced in healthy older adults during wakefulness compared to sleep, likely due to natural increases in body temperature when awake.

Rebecca Nisbet, a researcher at the Florey Brain Research Center in Australia, suggests that Whitney’s work-related heat exposure may contribute to his Alzheimer’s resistance, although genetics likely also play a role. “He may possess protective genes that others in his family do not,” she notes, referencing genes known to influence Alzheimer’s susceptibility.

Nonetheless, Nisbet has started using saunas herself, inspired by evidence indicating their brain health benefits. “I believe this harmless practice can significantly lower dementia risk,” she asserts.

Interestingly, regions with the lowest rates of cognitive impairment and Alzheimer’s disease in individuals over 60 typically experience high temperatures, such as Ballabhgarh, India, and the Bolivian Amazon. “While high temperatures alone aren’t a definitive explanation, they may play a part,” adds Canet.

On the contrary, exposure to cold may elevate Alzheimer’s risk. For instance, tau is known to dysregulate during bear hibernation, according to Nisbet. “The tau in a bear’s brain appears dysfunctional during hibernation but normalizes quickly upon warming,” she explains.

Human studies have also indicated that general anesthesia, which lowers body temperature, can lead to cognitive issues similar to those seen in Alzheimer’s, likely due to its impact on tau. “Caution is necessary in mouse studies since prolonged anesthetic exposure can lead to tau dysregulation,” Nisbett cautions.

An American man, Doug Whitney, whose genetics indicated a high likelihood of developing early-onset Alzheimer’s disease, has surprisingly managed to evade its effects. This remarkable outcome may be linked to unintentional heat exposure he experienced while working in a ship’s engine room, aligning with emerging evidence that suggests heat therapy could play a role in preventing symptoms of Alzheimer’s.

Whitney’s family carries the Presenilin 2 genetic variant, a mutation traced back to a small village in Volga, Germany, during the 18th century. Individuals with this mutation are typically predisposed to Alzheimer’s in their late 40s or early 50s.

“My family has been devastated by this disease,” Whitney remarked in a press statement. “My mother had 13 siblings, and 10 of them died before the age of 60. It was an epidemic.”

Despite sharing the same mutation, Whitney has reached his late 70s without experiencing significant memory loss or other Alzheimer’s symptoms, making him the only known mutation carrier to avoid the condition long after it was expected to manifest.

Dr. Jeffrey Kane from the French National Center for Scientific Research, became intrigued by Whitney’s case after discussing it with Dr. Randall Bateman, who has been studying Whitney for years.

At a conference, Kane presented research on the supportive effects of hyperthermia on mouse brains. A Finnish study found that frequent sauna users are 65% less likely to develop Alzheimer’s. Kane and colleague Emmanuel Planel from Université Laval in Quebec initiated a study to explore the underlying mechanisms.

The findings were compelling since Bateman knew of Whitney’s two-decade-long work in the extremely hot engine rooms of steam-powered naval vessels starting at age 18. Bateman discussed these circumstances with Kane and Planel, leading them to investigate further.

Engine room temperatures could soar up to 50°C (122°F), where Whitney would remain for extended periods, often needing to be hosed down to prevent overheating.

This prolonged heat exposure may have led to elevated levels of heat shock proteins in Whitney’s cerebrospinal fluid. These proteins are produced in response to heat and facilitate the repair and refolding of other proteins damaged by increased temperatures.

These heightened levels of heat shock proteins may have helped regulate tau, a crucial brain protein involved in Alzheimer’s disease. In affected individuals, tau misfolds and aggregates, which correlates with cognitive decline. Brain imaging studies reveal that Whitney’s brain holds negligible amounts of abnormal tau, likely explaining his absence of symptoms. Although his brain contains misfolded amyloid proteins associated with Alzheimer’s, symptoms remain unpredictable as evidenced in studies.

Whitney prepares for a PET scan in March 2025 as part of an Alzheimer’s Research Program at Washington University in St. Louis, Missouri.

Support for their hypothesis emerged when Kane and Planel discovered that exposing mice to heat helped maintain the tau protein structure and facilitated increased clearance from the brain. Moreover, tau clearance was found to be more efficient in awake older adults compared to when they sleep, likely due to the natural elevation of body temperature during wakefulness.

Dr. Rebecca Nisbet from Australia’s Florey Brain Research Center notes that Whitney’s occupational heat exposure may elucidate his resistance to Alzheimer’s, yet genetic factors likely contribute as well. Whitney may carry a specific protective gene absent in affected family members, highlighting the complexity surrounding Alzheimer’s disease.

Nisbet has personally begun using saunas, inspired by this new evidence of their cognitive benefits. “I believe this is a harmless activity that can mitigate dementia risk,” she asserts.

Interestingly, regions with the lowest rates of cognitive impairment and Alzheimer’s in individuals over 60 tend to be located in very hot climates, such as Ballabgarh, India and the Bolivian Amazon. “While high temperatures alone can’t explain everything, they may be a significant contributing factor,” reflects Canet.

On the contrary, cold exposure could heighten Alzheimer’s risk. For instance, tau exhibits dysregulation in bears during hibernation, according to Nisbet. “The tau in a hibernating bear appears abnormal, yet normalizes promptly upon waking and warming up,” she explains.

Research has shown that general anesthesia, which lowers body temperature, can contribute to short-term cognitive issues reminiscent of Alzheimer’s disease, potentially due to its effects on tau. “Caution is advised in mouse studies, as prolonged anesthesia can lead to tau dysregulation,” warns Nisbet.

Leaked API Keys

API Key Leaks: A Major Threat to Business Security

Critical security credentials, including API keys, are mistakenly exposed on thousands of websites, putting organizations—ranging from small startups to large banks and healthcare providers—at significant risk.

These leaks could grant unauthorized users access to sensitive data, like RSA private keys, enabling attackers to impersonate servers, decrypt private communications, and potentially seize complete control over a company’s digital infrastructure. “This is a pressing issue impacting entities of all sizes,” states Nurula Demir from Stanford University, California.

Demir and colleagues conducted an analysis of 10 million web pages to identify the extent of exposed API credentials. API keys facilitate seamless communication between different software systems and serve as access tokens for cloud platforms, payment processing, and messaging services.

Through their web scans, the researchers validated 1,748 exposed credentials from 14 leading service providers, including Amazon Web Services, Stripe, GitHub, and OpenAI, found across approximately 10,000 compromised websites.

The accountability for these vulnerabilities lies not with the service providers, but with the developers and operators who misconfigured their websites. While the specific companies affected were not named, they reportedly include “global systemically important financial institutions,” firmware developers, and major hosting platforms.

“We have alerted all entities concerning identified exposures,” said DeMille. Approximately half of the organizations remedied their exposed API keys within two weeks; however, some did not respond.

On average, leaked credentials remain accessible for 12 months, with some lasting as long as five years. The majority (around 84%) of compromised credentials were located within the JavaScript environment, likely due to developers improperly using bundler tools for code packaging.

The remaining 16% originated from third-party resources, where misconfigured external plugins or scripts inadvertently exposed sensitive credentials online.

“None of these developers intended for their systems to be insecure,” explains Katie Paxton-Fear from Manchester Metropolitan University, UK. Issues arose due to programming intricacies, leading to accidental exposure. “They followed best practices, but vulnerabilities emerged during the development process,” she adds.

Leaking API keys is a “significant concern in modern software development,” notes Nick Nikiforakis from Stony Brook University, New York. “API keys replace user credentials, granting authorization without direct authentication. However, their misconfiguration can lead to serious security threats.”

DeMille emphasizes shared responsibility in addressing these vulnerabilities. “Developers must exercise caution in using API credentials,” he advises, alongside ensuring proper configuration of their development environments. He further suggests website-building tool creators should design systems to automatically hide private keys by default, rather than relying on developers to manage these protections manually, and that hosting companies should proactively monitor for exposed keys and disable them immediately.

Measuring giant corals

Iñigo San Felix/National Geographic Society

A gigantic underwater structure off the coast of the tropical Solomon Islands in the southwestern Pacific Ocean has been confirmed to be the world's largest known coral.

A team of scientists and filmmakers visited a remote location in mid-October national geographic The object was so large that I thought it must be the remains of a shipwreck.

However, for underwater cinematographers, Manu Saint Felix Jumping into the water to get a better look, he was surprised by what he saw.

“I completely remember jumping up and looking down, but I was surprised,” he told reporters during a briefing. Instead of a shipwreck, San Felix encountered the largest coral ever discovered. “It's huge,” he said. “It's almost the same size as a cathedral.”

A coral species located a few hundred meters off the east coast of Marauralo Island was identified as this species. Pavona Kraus. At 34 meters wide and 32 meters long, it is larger than a blue whale and is thought to be 300 years old.

He says the discovery was a “happy coincidence”. enric sala of national geographic's Pristine Seas project aims to encourage governments to protect marine ecosystems through exploration and research. This is by far the largest single coral colony ever discovered, easily surpassing this one. previous record holder – giant porphyry A colony with a diameter of 22.4 meters and a height of 8 meters discovered in American Samoa in 2019.

Over the past two years, record sea temperatures have led to a series of coral bleaching events around the world. But Sala says the giant reef is showing signs of bleaching, while other reefs around the Solomon Islands are showing signs of bleaching. P. Cravath The coral looks healthy. It is an important habitat for marine life, providing shelter and food for fish, shrimp, insects and crabs, he says. “It’s like a big patch of old-growth forest.”

However, corals are not immune from ecological threats, including local pollution, overfishing, and global climate change. Sala said he would like to see more marine protected areas (MPAs) established to protect marine life from localized pollution, in parallel with global efforts to combat climate change. . “Protecting coral reefs won't lower water temperatures, and it won't stop oceans from warming,” he says. “We need to fix it, and we need to reduce carbon emissions. But MPAs can help buy us time by making reefs more resilient.”

NASA had to reassure the public that there was no emergency on the International Space Station after audio from a medical training drill was mistakenly played during a livestream on Wednesday night.

The regularly scheduled livestream was interrupted at 6:28pm ET by an unidentified speaker, apparently a flight surgeon, communicating with the ISS crew about what to do for the commander, who was suffering from severe pressure illness.

The speaker advised crew members to “check the pulse again” before placing the injured astronaut in a spacesuit filled with pure oxygen. She said any treatment was “the best treatment” and better than nothing.

“Unfortunately, Commander's prognosis is relatively uncertain,” she said.

“I'm concerned that there are people with severe DCS,” she said. [decompression sickness] He “hits” and tells the crew to get him suited up as quickly as possible.

She mentions that there is a hospital in San Fernando, Spain, with a hyperbaric treatment facility, apparently implying that she would order an emergency evacuation of the space station.

But after stirring up fear among space enthusiasts listening in, NASA revealed that this scenario wasn't real: All crew members aboard the ISS were safely asleep at the time.

NASA said there was “no emergency on board the International Space Station.”

“At approximately 5:28 p.m. CDT, audio was broadcast on NASA's livestream from a ground-based simulated audio channel indicating the crew member was experiencing symptoms associated with decompression sickness,” NASA said in a statement. X's message.

“The audio was inadvertently transmitted from an ongoing simulation in which crew and ground teams were training for various scenarios in space and is not related to an actual emergency,” NASA said in a statement.

“The International Space Station crew was asleep at the time. All crew members are healthy and safe, and tomorrow's spacewalk will begin as scheduled at 8 a.m. EDT,” it added.

The emergency training came after two astronauts aboard Boeing's Starliner spacecraft successfully docked with the ISS last week.
