H5N1 infections remain rare among workers exposed to infected birds

A two-year cohort study of 428 people exposed to H5N1-infected birds in England found fewer than 1% met criteria for infection, with no severe disease or secondary human transmission. The findings support continued PPE use, biosecurity, and targeted surveillance while highlighting challenges around occupational exposure, mucosal contamination, and pandemic preparedness.

Study reveals how wind helps animals track hidden odors

Humans trust dogs to help find missing people and bees to pollinate their crops. But scientists still don't fully understand how these animals use their extraordinary sense of smell to locate the source of an odor.

Circular eccDNA shows potential to predict early-stage LUAD recurrence

LUAD is the most common histological subtype of lung cancer. Although surgery can be curative for patients diagnosed at an early stage, approximately 30%-50% develop recurrence or aggressive metastasis within five years.

Two British birth cohorts find no added health burden from a coastal childhood

Researchers analyzing two British birth cohorts found no association between coastal residence in adolescence and midlife multimorbidity, while an unadjusted association in the 1958 cohort weakened after accounting for neighborhood deprivation.

Penn State study identifies genetic regions linked to avian herpesvirus virulence

A highly contagious herpes virus causes Marek's disease, a deadly illness that mainly infects chickens. While it does not make people sick, the virus causes tumors and paralysis in chickens and, if unchecked, can spread rapidly through entire flocks.

Study links ancient evolutionary pressures to severe COVID-19 risk

Every time a virus invades a person, it collides with thousands of years of human history. A study led by researchers at the USC Dornsife College of Letters, Arts and Sciences and Howard University suggests that some of the genes involved in the body's immune response today bear the marks of ancient battles with infectious diseases.

Cells share universal on switches but evolve unique strategy to silence genes

The signals that cells use to switch genes on have remained almost unchanged across two billion years of evolution, but the ones used to switch genes off vary dramatically from one branch of life to another, according to a new study from the Centre for Genomic Regulation (CRG) in Barcelona.

Cooperative sperm may improve fertilization success across diverse arthropods

Fertilization is often imagined as a frantic race, with millions of sperm competing for a single prize. But new research by a team of evolutionary biologists from Syracuse University, University of Siena, Italy, and University of Szeged, Hungary, reveals a more surprising reality, where success can depend less on competition and more on cooperation.
