Risk of COVID-19 in adolescents vs older adults

According to a recent study published in JAMA Network Open, adolescents were found to have a significantly higher incidence rate and relative risk of COVID-19 infection from wild-type SARS-CoV-2 compared to older adults. The study analyzed data from the start of the pandemic through fall 2020 across 16 of the 19 states examined.

Best available therapy for AIDS-associated Kaposi sarcoma is cost effective in Africa

Researchers at Massachusetts General Hospital found that paclitaxel improves clinical outcomes and is cost-effective compared to commonly used treatments in Kenya. Using paclitaxel instead of bleomycin-vincristine could save 6,400 years-of-life and reduce healthcare expenditures by $3.7 million over five years.

An Achilles heel shared by plants and animals

Researchers discovered that diphthamide is formed in plants and plays a crucial role in protein biosynthesis, with reduced growth rates observed when its formation is impaired. Environmental stressors such as copper and cadmium also inhibit diphthamide production, highlighting a new factor influencing plant growth rates.

Online parenting skills program shields children from adverse effects of divorce

A new online parenting skills program has been shown to reduce interparental conflict, improve quality of parenting, and decrease anxiety and depression symptoms in children of divorcing parents. The eNew Beginnings Program, adapted from a 30-year research study, benefits over 1 million children affected by divorce each year.

Deformable pump gives soft robots a heart

A team of researchers from Cornell University has developed a deformable pump for soft robots, mimicking the human heart's functionality. The pump uses hydrodynamic and magnetic forces to provide soft robots with a circulatory system, allowing them to store energy and power their movements more efficiently.

Y-chromosome loss due to aging and other factors worsens prognosis for heart failure

Research finds that losing the Y chromosome increases mortality from cardiovascular disease by up to 1.76 times, with a significant link between Y-chromosome loss and fibrosis promoting heart failure. The study also shows that cardiac macrophages without the Y chromosome produce substances that activate fibroblasts, leading to fibrosis.

Study finds treating precancerous growths in people with HIV reduces anal cancer by more than half

Researchers have found that treating high-grade squamous intraepithelial lesions (HSILs) in people with HIV significantly decreases the progression to anal cancer. The ANCHOR trial enrolled over 4,000 participants and showed a 57% reduction in anal cancer cases.

The historical roots of a contemporary groundwater crisis

A new study reveals how large-scale groundwater exploitation by local farmers led to the desiccation of sandy soils and decimation of wildlife populations in Spain's Doñana National Park. The lack of effective oversight created an economically and environmentally unsustainable situation, destroying a protected natural space.

Poxvirus proteins enable early strike on immune defences

A new study identifies pox virus proteins that directly interfere with the body's innate immune system, allowing it to evade the host's defense mechanisms. The research team has discovered five 'redox' proteins that interact with Reactive Oxygen Species, which play a key role in destroying pathogens identified by the immune system.

Coastal glacier retreat linked to climate change

Researchers developed a methodology to attribute coastal glacier retreat to human-caused climate change, revealing that even modest global warming causes most glaciers to melt or retreat. The approach simulates the behavior of real ice sheets like Greenland's, helping predict major ice loss and informing decision-making for policymakers.

Men over 40 who regularly eat sunomono more likely to be in lower blood pressure category

An observational study by Osaka Metropolitan University found that men over 40 who regularly eat sunomono are more likely to be in the lower blood pressure category. The study suggests that vinegar consumption, particularly through sunomono, may promote growth of good gut microbiota and have a positive impact on health.
