Through a multi-university collaboration, researchers at Virginia Tech have discovered a new, solid lubricating mechanism that can reduce friction in machinery at extremely high temperatures. It works well beyond the breakdown temperature of traditional solid lubricants such as graphite, and the findings were published in Nature Communications.  “This breakthrough solid-state lubricant could change how we design materials for high-tech engines, making them last longer and work better under extreme conditions,” said Rebecca Cai, associate professor in the Department of Materials Science and Engineering and one of the ...

The stereotype that women are much more talkative than men is pervasive across many cultures, but a widely reported study by University of Arizona researchers in 2007 refuted the claim, finding that men and women speak roughly the same number of words per day – around 16,000.  A new, larger follow-up to that study paints a more nuanced picture, suggesting that women may be the chattier gender, but only during a certain period of life.  "There is a strong cross-cultural assumption that women talk a lot more than men," said ...

In physics, the term “isotropy” means a system where the properties are the same in all directions. For fusion, neutron energy  isotropy is an important measurement that analyzes the streams of neutrons coming from the device and how uniform they are. This is critical because so-called isotropic fusion plasmas suggest a stable, thermal plasma that can be scaled to higher fusion energy gains, whereas anisotropic plasmas, those emitting irregular neutron energies, can lead to a dead end. A new Zap research paper, published last week ...

A new study has estimated it would cost $15.6 billion per year for 30 years to prevent extinction for 99 of Australia’s priority species.  The research, led by Griffith University’s Centre for Planetary Health and Food Security with WWF-Australia and the University of Queensland, highlights the urgent need for increased funding to combat threats such as habitat destruction, invasive species and climate change. Australia has already lost more than 100 endemic species in the past three centuries, placing it at the forefront of the global extinction crisis.  The ...

The octopus just revealed another one of its secrets: what determines its sex.  University of Oregon researchers have identified a sex chromosome in the California two-spot octopus. This chromosome has likely been around for 480 million years, since before octopuses split apart from the nautilus on the evolutionary tree. That makes it one of the oldest known animal sex chromosomes.   The finding also is evidence that octopuses and other cephalopods, a class of sea animals that includes squid and nautiluses, do use chromosomes to determine their sex, answering a longstanding mystery among biologists.   “Cephalopods are already such interesting creatures, ...

Rice cultivation is responsible for around 12% of global methane emissions, and these emissions are expected to increase with global warming and as the human population continues to grow. Now, scientists have identified chemical compounds released by rice roots that determine how much methane the plants emit. On February 3 in the Cell Press journal Molecular Plant, they report that this information enabled them to breed a new strain of rice that emits up to 70% less methane.  “This study shows that you can have low methane and ...

Alarming Rise in Rates of Advanced Prostate Cancer in California  Following a change in screening guidelines, the incidence went up across the state, even more than it has nationally. The incidence of advanced prostate cancer in California rose markedly in the decade since doctors stopped routinely screening all men for the disease, according to a new study by UC San Francisco. After declining for many years, the death rate from the disease also plateaued in most regions across the state. The findings reinforce the need for screening that can identify potentially fatal tumors without raising false alarms about ones that pose no threat to the patient.  The ...

For years, healthy older adults were advised by doctors to take a low-dose aspirin daily as a way to reduce the risk of heart attack. But in March 2019, the American College of Cardiology and the American Heart Association (AHA) announced new guidelines and no longer routinely recommended a daily dose of aspirin for healthy adults over the age of 70 because the risk of gastrointestinal bleeding outweighs the benefits. Nearly five years later, many Americans still have not received the message. The Annenberg Public Policy Center (APPC) of the University of Pennsylvania finds in a new health survey that nearly half (48%) of U.S. ...

Secondary prevention medications for cardiovascular diseases (CVD) are underused globally and additional strategies to increase their use are needed to improve CVD management and reduce premature mortality rates, according to study published today in JACC, the flagship journal of the American College of Cardiology. The study observed participants with CVD from 17 countries over 12 years and found that medication use remains low with little improvement. Secondary prevention of CVD focuses on preventing further health problems in people already diagnosed with CVD. This includes managing risk factors through lifestyle changes, medications and ...

Approximately half of all Americans do not take their medication as prescribed by their doctor.

Emerging evidence suggests that lycopene—a natural plant extract—may have antidepressant properties. New research in Food Science & Nutrition reveals the mechanisms behind its antidepressant effects. In mice with depressive-like behaviors, brain analyses revealed impairments in the hippocampus. Lycopene treatment lessened these impairments and reversed the animals’ depressive-like traits. Lycopene treatment boosted the expression of brain-derived neurotrophic factor (BDNF), a protein with roles in many aspects of brain function. Experiments indicated that a signaling pathway involving BDNF (called the BDNF-TrkB pathway, ...

Researchers at Vanderbilt and the University of Michigan have shown that a simple at-home urine test for prostate cancer screening is highly accurate. The exciting new results, published in The Journal of Urology, build upon a prior Vanderbilt study of prostate cancer screening that required a digital rectal exam.   The results are important because this could enable at-home testing and increased access to testing for patients undergoing telehealth care or living in remote areas. Traditional prostate cancer screening with PSA testing and biopsy has been shown to lead to unnecessary procedures and overdiagnosis of low-grade cancers, according to ...
