Intermittent fasting, and fasting in general, has been a popular fad health gimmick, but the science isn't on its side. Instead, proponents believe mice are little people so if mice weaned on starvation diets lived longer, people would also.
A recent study describes a new species of vampyropod based on a 328-million-year-old fossil and pushes back the age of the group by nearly 82 million years. And shows that the oldest ancestors of the group of animals that includes octopuses and vampire squids had not eight but 10 arms. Vampyropods are soft-bodied cephalopods typically characterized by eight arms and an internalized chitinous shell or fin supports. Because they lack hard structures, Vampyropoda are not well represented in the fossil record. The new study is based on a vampyropod fossil from the collections of the Royal Ontario Museum. It was originally discovered in Montana and donated to the museum in 1988.
Few treatments exist for COVID-19 and the ones that do primarily focus solely on preventing the virus from replicating. A new potential treatment inhibits replication but also protects or repairs tissue, which is important because COVID-19 can cause symptoms that affect patients long after the viral infection has been cleared. It is a biologic substance created by reengineered human skin cells called dermal fibroblasts.
Electric cars are being artificially bolstered by government mandates and subsidies and are doing little to reduce emissions because the electricity they need is overwhelmingly not solar, nuclear, or hydroelectric.What would help are batteries that aren't stuck in the 20th century, like lithium-ion, which cost so much to replace that one Tesla owner blew up his car with dynamite rather than a cost for new batteries that was 50 percent of the original purchase price. And they can be dangerous.Lithium-ion explosion risk
Being a woman is correlated to being twice as men to develop Alzheimer's disease, but lacking a scientific foundation for why, epidemiology is limited to noting it on a population level and moving on.A new paper seeks to create a biological hypothesis. The authors say the C/EBPβ/AEP pathway is the core factor driving the pathogenesis of neurodegenerative diseases and searched for female hormones that are dramatically changed during menopause and tested which hormone selectively activates the C/EBPβ/AEP pathway. They have identified follicle-stimulating hormone (FSH) as the major pathogenic factor.
President Biden is touting his strong economic performance but the public disagrees; his approval rating is in the 30th percentile because an expanding economy as framed by politicians still means high inflation to people paying taxes. The psychological impacts of bad economic performance are evident also; when times are good, spending makes people happy. When times are bad, spending is stressful. Customers even leave worse reviews, according to a new paper.
One of the most important examples of early art in Europe, a 11 cm high figurine colloquially dubbed a 'Venus' and found in Willendorf, Austria, is made of a rock called "oolite" which is not found in or around Willendorf. New high-resolution tomographic images lead the authors to concluse the material from which the Venus was carved likely comes from northern Italy or possible eastern Ukraine, which sheds new light on the mobility of the first modern humans south and north of the Alps.
A new analysis of human remains from ancient DNA of six individuals buried in Malawi, Tanzania and Zambia who lived between 18,000 and 5,000 years ago has produced the earliest DNA from the continent, and giving some insight into how early humans lived, traveled and even found love. The study also reanalyzed published data from 28 individuals buried at sites across the continent, generating new and improved data for 15 of them. The dataset of DNA from ancient African foragers reveals a genetic legacy difficult to reconstruct from present-day people because of the many population movements and mixtures that have occurred in the last few thousand years.
There is a myth that people act differently during a full moon but nurses swear by it because of perception of an increase in emergency room cases. Now demographers have linked heat waves to emergency care, except the mental health kind.The paper correlated days with higher-than-normal temperatures during the summer season in the United States to increased rates of emergency department (ED) visits for any mental health-related condition, particularly substance use, anxiety and stress disorders, and mood disorders.
Fast Radio Bursts (FRBs) are millisecond-long bursts of radiation recorded on radio waves. They are extremely powerful - for example, during one of the brightest flashes lasting five milliseconds, as much energy is radiated as our Sun generates in a month. The scale of the phenomenon is difficult to imagine. A new study tracks down their source.
HIV normally uses the CCR5 co-receptor to help it infect immune cells, but the receptor’s Δ32 variant effectively blocks viral entry but a 14-month success story using cord blood containing an HIV-resistance gene variant called CCR5Δ32 means HIV has been cured in a patient.
If you watched film and television from an alien spacecraft, you'd wonder how the same government that created a CDC which needs 6 weeks to tell the public that lettuce has E. coli on it can also create "Mission Impossible" plots and shows where FBI agents win every time.The first part is real, the last is certainly fiction. A new study finds that not only is a government database wrong, it is wrong to an extent that is worrisome when we want people to have more trust in law enforcement agencies.
Protection of personal data in the Internet Age is a big worry but solutions may be lacking. A smartwatch may seem secure, but the neural network processing that health information is using private data that could still be stolen by a malicious agent through a side-channel attack - one in which secret information is gathered by indirectly exploiting a system or its hardware. In one type of side-channel attack, a hacker could monitor fluctuations in the device’s power consumption while the neural network is operating to extract protected information that “leaks” out of the device.
