Scientists at Berkeley Lab and UC Berkeley have created an ultrathin magnet that operates at room temperature. The ultrathin magnet could lead to new applications in computing and electronics - such as high-density, compact spintronic memory devices - and new tools for the study of quantum physics.

An internal transporter that enables us to use the copper we consume in foods like shellfish and nuts to enable a host of vital body functions also has the essential role of protecting the receptor that enables us to grow new blood vessels when ours become diseased, Medical College of Georgia scientists report.

Study finds medications prescribed for children dropped by more than a quarter during the first eight months of the pandemic compared to the previous year, with the steepest declines in infection-related medicines like antibiotics and cough-and-cold drugs.

Tomato fruits inform the mother plant when they are being eaten by caterpillars, shows a new study. Little is known about whether a fruit can communicate with the plant to which it's attached, which could be important for warning the plant of threats. This early evidence shows that pest attacks do trigger defensive electrical and biochemical responses across the plant. This could provide more effective monitoring strategies for detecting agricultural pests in the future.

An international team of researchers led by Kumamoto and Tokyo Universities (Japan) have shown that the L452R mutation of the SARS-CoV-2 spike protein, which is common to two variants (Epsilon and Delta), is involved in cellular immunity evasion via the human leukocyte antigen (HLA) A24, and enhances viral infectivity. HLA-A24 is one of the most prominent HLA-class I alleles, especially in East/Southeast Asian populations, which might make them particularly vulnerable to variants with the mutation.

Using data from 9,859 COVID-19 infections, Mayo Clinic researchers have new insights into risk factors for younger populations, some of which differ significantly from their older counterparts. People younger than 45 had a greater than threefold increased risk of severe infection if they had cancer or heart disease, or blood, neurologic or endocrine disorders, the research found. These associations were weaker in older age groups. The study was published in Mayo Clinic Proceedings.

High school students who participated in summer programs about public health increased their interest in pursuing careers in science, technology, engineering and mathematics (STEM), according to a Rutgers study.

Black holes with masses equivalent to millions of suns do put a brake on the birth of new stars, say astronomers. Using machine learning and three state of the art simulations to back up results from a large sky survey, the researchers resolve a 20-year long debate on the formation of stars. Joanna Piotrowska, a PhD student at the University of Cambridge, will present the new work today (Tuesday 20 July) at the virtual National Astronomy Meeting (NAM 2021).

One in eight children have mental disorders that cause symptoms and impairment and therefore require treatment, but even in high-income countries most of these children will not gain access to services to treat them, reports a study published in the journal Evidence-Based Mental Health.

Although lockdowns are undoubtedly associated with health harms, their impact on health is unlikely to be worse than the impact of the COVID-19 pandemic itself, concludes a review published in the online journal BMJ Global Health.

The case of a patient who experienced two facial palsies - one after the first and another after the second dose of the Pfizer-BioNTech COVID-19 vaccine - strongly suggests that Bell's palsy (facial nerve palsy of unknown cause) is linked to the Pfizer-BioNTech vaccine, doctors write in the journal BMJ Case Reports.

Two common practices in the U.S. restaurant industry -- service with a smile and tipping -- contribute to a culture of sexual harassment, according to new research from the University of Notre Dame.

An observational study in Barcelona, Spain found that implementation of same-day rapid screening, use of face masks, and improved ventilation was associated with very low rates of SARS-CoV-2 transmission at an indoor mass-gathering live concert without physical distancing. The brief research report is published in Annals of Internal Medicine.

Although people in early 2020 were highly cautious about COVID-19, 11 months later the public pushed the envelope on pandemic safety precautions and ignored warnings as time went on, a new University of California, Davis, study suggests.

Researchers at the University of Maryland School of Medicine (UMSOM) launched a new online tool that could more quickly advance medical discoveries to reverse progressive hearing loss. The tool enables easy access to genetic and other molecular data from hundreds of technical research studies involving hearing function and the ear.

A Michigan State University researcher is leading an international team of scientists to develop a low-cost, practical biopolymer dressing that helps heal chronic wounds.

New research examines commuter characteristics to better understand how factors such as departure time, frequency, and commute length are associated with exposure to air pollution. Using personal air pollution monitors, the research clustered commuters to determine whether these clusters were associated with traffic pollution exposures. The study reveals that commuters that travel during rush hour have higher overall exposure to traffic-related air pollution compared to sporadic commuters, though the difference was not statistically significant.

Researchers at Michigan Medicine have discovered another functional autoantibody in COVID-19 patients that contributes to the disease's development and the "firestorm" of blood clots and inflammation it induces. The autoantibody makes it much harder for the body to degrade neutrophil extracellular traps, the toxic webs of DNA and proteins produced by overactive immune cells at heightened levels in COVID patients.

We must not assume that we will be able to replicate a vaccine within 12 months during the next pandemic. Even if this was accomplished, other interventions would be required to control and mitigate well before the availability of a vaccine.

George Mason University's Dr. Michelle Williams shares program evaluation results determining the feasibility of offering free, same-day cancer screening and health education to reduce disparities. The program examined how access to free screenings affects participants' knowledge about cancer, self-efficacy for obtaining healthcare, and intentions to change health behaviors. The program had a positive effect on participant's knowledge of cancer screenings and self-efficacy for seeking regular check-ups.
