Newly-discovered protein acts as off switch for human immune cells

Mayo Clinic researchers have identified a protein that cancer cells use to shut down the body's immune response, a discovery that could help scientists develop new treatments that make cancer immunotherapies more effective.

Automated oxygen delivery system improves precision for hospitalized patients

A University of Colorado Anschutz-led clinical trial has found an automated oxygen delivery system helped hospitalized patients spend significantly more time in their target oxygen range compared with standard care, while also reducing exposure to both low and high oxygen levels.

Study uncovers brain mechanism that drives sustained motivation

What enables us to sustain effort toward goals, even when the task becomes increasingly difficult? A recent study by researchers at Nagoya University in Japan revealed the underlying brain mechanism, showing that orexin neurons play a crucial role in driving and regulating motivated behavior.

A 10-country survey finds an unexpected air pollution awareness gap

Researchers surveyed 10,618 adults across 1,372 localities in the world’s 10 most populous countries and matched their responses with average 2019-2021 PM2.5 concentrations. Higher PM2.5 exposure was associated with lower air-quality knowledge but greater concern and more frequent protective behaviors, with patterns differing across demographic groups.

Traditional Japanese medicine for obesity may help reduce age-related tissue fibrosis

A traditional Japanese medicine used for obesity may do more than support weight loss. Researchers at the University of Osaka, working with Kobayashi Pharmaceutical Co., Ltd. investigated whether Bofutsushosan could protect aging tissues from fibrosis - the excessive buildup of scar-like tissue that can make organs stiff and less functional.

Immune cell changes provide new insights into long COVID

Extreme fatigue, a racing pulse, shortness of breath, brain fog, aching joints-the symptoms of long COVID can vary widely, change unpredictably, and be difficult to even recognize as signs of the condition.

Daytime cortisol patterns track cognitive decline but not Alzheimer’s disease risk

In 3,895 older adults, moderate daytime cortisol variability was associated with better cognition and slower decline, while the highest daily cortisol exposure was linked to poorer cognition and faster decline. Cortisol patterns differed between Black and White participants, but their relationships with cognition were similar, and none predicted incident Alzheimer’s disease.

Study links higher body fat to lower sperm counts despite normal BMI

Among 1,058 Danish men, higher body fat percentage was associated with lower total sperm count and altered reproductive hormone levels, but not testicular volume. Body fat percentage showed stronger links with several semen measures than BMI or waist-to-height ratio, with the sperm-count association strengthening among men with normal BMI.
