Summary: Physical activity enhances the ability to learn and remember motor skills. The new research involved 67 young men and explored how exercise before and after motor skill learning impacts memory retention.

The study found that exercising both before and after learning optimizes memory formation, with a notable 10% improvement in remembering motor skills. This research is significant for various fields, from rehabilitation to skill training, demonstrating that incorporating physical activity can enhance learning effectiveness.

Using a biosensor to detect cystic fibrosis as the test case, TU/e researchers have devised an innovative way to train neuromorphic chips as presented in a new paper in Nature Electronics.

Neuromorphic computers—which are based on the structure of the human brain—could revolutionize our future health care devices. However, their widespread use is hindered by the need to train neuromorphic computers using external training software, which can be time-consuming and energy inefficient.

Researchers from Eindhoven University of Technology and Northwestern University in the U.S. have developed a new neuromorphic biosensor capable of on-chip learning that doesn’t need external training. As a proof-of-concept, the researchers used the biosensor to diagnose cystic fibrosis based on sweat samples.

Mesolithic Scandinavians likely faced oral health issues, with studies on ancient birch tar revealing signs of gum disease, tooth decay, and diverse dietary habits.

Members of a hunter-gatherer group that lived in south-western Scandinavia during the Mesolithic era — approximately 10,000 years ago — may have been affected by tooth decay and gum disease, according to a study published today (January 18) in Scientific Reports.

Three different HIV antibodies each independently protected monkeys from acquiring simian-HIV (SHIV) in a placebo-controlled proof-of-concept study intended to inform development of a preventive HIV vaccine for people. The antibodies—a human broadly neutralizing antibody and two antibodies isolated from previously vaccinated monkeys—target the fusion peptide, a site on an HIV surface protein that helps the virus fuse with and enter cells. The study, published in Science Translational Medicine, was led by the Vaccine Research Center (VRC) at the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health.

Antibodies that target the fusion peptide can neutralize diverse strains of HIV in vitro, that is, in a test tube or culture dish outside of a living organism. The NIAID VRC isolated a fusion peptide-directed human antibody, called VRC34.01, from a person living with HIV who donated blood samples for research. They also isolated two antibodies from rhesus macaques—a species of monkey with immune systems like humans’—who previously had received a vaccine regimen designed to generate fusion peptide-directed antibodies. Demonstrating that these antibodies protect animals would validate the fusion peptide as a target for human vaccine design. SHIV challenge—administering an infective dose of SHIV—to rhesus macaques is a widely used animal model for assessing the performance of HIV antibodies and vaccines.

In this study, rhesus macaques in each of four groups received a single intravenous infusion of one type of antibody—a 2.5 or 10 mg/kg of bodyweight dose of VRC34.01, or one of the two vaccine-elicited rhesus macaque antibodies—and other monkeys received a placebo infusion. To determine the protective effect of the antibodies, each monkey was challenged five days after infusion with a strain of SHIV known to be sensitive to fusion peptide-directed antibodies.

“We combined the predictive model with patient feedback from the PCI Patient Advisory Council to transform machine learning into this patient-centered, individualized risk prediction tool,” said senior author Hitinder Gurm, MBBS, interim chief medical officer at U-M Health.

The tool can help you and your doctor make informed decisions about your treatment. It can also educate you about the potential risks and benefits of PCI. By using the tool, you can have more confidence and control over your health.

The researchers hope that the tool will improve the quality and safety of PCI, and ultimately, save lives.

Given the value of the vaccine, it’s mindboggling that some in the US would choose not to protect their children. And yet, vaccine rates among US kindergartners fell for the second consecutive year in 2022, a situation the Centers for Disease Control and Prevention said left some 250,000 kids vulnerable to measles. While some of those missed shots were potentially due to challenges accessing timely health care during the pandemic, there’s reason to worry that growing hesitancy about vaccination is also at play.

It does not help that some states are making it easier to forgo routine childhood vaccines. Mississippi, for example, previously led the nation in vaccination coverage for kindergarteners, with more than 98.6% of kids receiving both doses of their MMR shots in the 2021–2022 school year. But anti-vaccine activists succeeded in loosening the state’s childhood vaccination policy, and last year families could for the first time seek religious exemptions for basic shots like MMR, tetanus, polio and others. According to a report from NBC, the state granted more than 2,200 exemptions in the first five months they were allowed.

The shift seemingly reflects a new partisan divide. A recent Pew Research Center poll found a steep drop in the number of Republicans and people who lean Republican who don’t believe vaccines should be required for attending public school.

Research indicates enhanced mental function in individuals who maintain an active lifestyle and engage in social interactions, alongside managing blood pressure and diabetes effectively.

As federal approval for more Alzheimer’s disease medications progresses, a recent study conducted by UC San Francisco and Kaiser Permanente Washington reveals that tailored health and lifestyle modifications can postpone or prevent memory deterioration in older adults at increased risk.

The two-year study compared cognitive scores, risk factors, and quality of life among 172 participants, of whom half had received personalized coaching to improve their health and lifestyle in areas believed to raise the risk of Alzheimer’s, such as uncontrolled diabetes and physical inactivity. These participants were found to experience a modest boost in cognitive testing, amounting to a 74% improvement over the non-intervention group.

New sleep technology was a trend at CES 2024, and health company DeRucci showcased its new line of smart bed products — including a pillow to combat snoring.

At CES 2024, a Chinese-based company presented what it claims is the first smart, antisnoring pillow.
