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.

RNA-based therapeutic strategy targets brain pathway behind cancer-associated cachexia

A new path has opened toward stopping cancer-associated cachexia, a devastating complication that gradually wastes patients away.

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.

Blocking xenophagocytosis improves donor cell survival and interspecies organ generation

Xenophagocytosis is a natural immune process that limits interspecies organ generation by eliminating living donor cells, report researchers at Institute of Science Tokyo, Japan.

Researchers uncover hierarchical sensory processing system in the zebrafish brain

How does the brain make sense of what we see, hear, and feel—and transform these separate signals into a coherent perception of the world?

New discovery advances sustainable production of plant-based medicines

Two plants that cause neurotoxicity and paralysis in the tiniest doses are also known to counter pain, malaria, cancer and pests.

Ketamine boosts neuroplasticity through microglia in female brains

Doctors use ketamine on patients as general anesthesia before surgery. They also prescribe it in low doses for pain management, and more recently, it's been used for treatment-resistant depression where other drugs have failed.

Study offers a potential strategy to make nanoparticle-based cancer drugs more effective

A new study led by researchers at The University of Texas MD Anderson Cancer Center has identified a way to reshape the gut microbiome that can enhance the delivery of certain chemotherapies to tumors, offering a potential strategy to make nanoparticle-based cancer drugs more effective.

Secondhand smoke alters tooth enamel development in early life

Exposure to secondhand cigarette smoke during the first days of life can cause changes in tooth enamel mineralization without causing visible changes to the teeth.
