COVID-19 immunity shows cross-reactivity against related bat coronaviruses

People who recovered from COVID-19 infection or were vaccinated against SARS-CoV-2 are more likely to have immunity to other closely related bat coronaviruses that could have the potential to threaten future human health.

New study reveals how VEGF-C amplifies lymphangiogenic signaling

Lymphatic vessels act as the body's "drainage system," collecting excess fluid from tissues. When lymphatic drainage is impaired because lymphatic vessels are underdeveloped, damaged, or dysfunctional, lymphedema can develop, causing swelling, particularly in the arms and legs.

Ultrasensitive AMH testing offers new insights into midlife ovarian reserve

In women's lifelong health management, the years from 35 to 55 form a critical transition period. During this period, many women face a triple challenge: declining fertility, bothersome perimenopausal symptoms, and delayed or delays in recognizing or confirming menopause.

$Longer spaceflight linked to increased hip fracture rates in astronauts$

Longer spaceflight linked to increased hip fracture rates in astronauts

New research has found that the rate of hip fractures in astronauts back on Earth was greater in the time period after an astronaut has been in space for more than 90 days than in the time period following shorter spaceflights or in non-astronauts.

Sex chromosomes influence immunity, cancer, aging and disease risk

A new review published in Science brings together growing evidence that the X and Y chromosomes do much more than determining biological sex. They also shape how cells function, age and respond to disease.

Phage proteases activate bacterial immune response to viral infection

In the fight to find better treatments for bacterial infections, one rapidly evolving therapy is a group of viruses called bacteriophages (phages). Phages can attack and kill dangerous bacteria while leaving human cells unharmed and bypassing antibiotic resistance.

Loss of tumor suppressor p53 reshapes Wnt signaling to drive mutant cell expansion

A protein known as p53 is, of all tumor suppressors in human cancer, the most frequently altered by gene mutations.

Mitochondrial protein SLC25A34 links body clock, cold and diet to brown fat metabolism

Brown fat burns fuel to make heat, and this activity is controlled by the body clock: dropping during sleep and rising before waking. But a cold morning or a skipped meal makes demands the clock never planned for.

Spatial mapping reveals macrophage niches linked to severe COVID-19 lung injury

Researchers at the University of Liège have used imaging-based spatial single-cell transcriptomics to map the cellular organization of lungs from people who died with severe COVID-19.

New fluorescent paper strips make vitamin B12 testing simpler

Measuring vitamin B12 in food usually means bringing the sample to the laboratory. A new fluorescent sensor could help move part of that process onto something much simpler: a paper strip or cotton swab.

Common gene variant reduces effectiveness of pediatric asthma drug

Children with a variant in the SERPINE1 gene – which is found in 60% of the population – may be less responsive to mepolizumab, a drug used to treat asthma flares, according to a study published in the Journal of Allergy and Clinical Immunology.

Novel 'speech clock' can estimate a person's chronological age

A large study shows that machine-learning clocks based on speech can estimate chronological age and may also offer a window into brain aging, biological aging, cognitive health, cumulative burden, and dementia.
