A Vitamin B Deficiency Marker May Be Associated With Chronic Fatigue
Studying role of poor nutrition in chronic fatigue, researchers found that higher homocysteine levels—a marker often associated with vitamin B deficiency—were linked to greater fatigue and lower motivation.
Japan’s Invasive Raccoons May Be Spreading Food Poisoning Bacteria
A genetic analysis of river water, wild raccoons and human infections suggests Japan's invasive raccoons may help spread Escherichia albertii, a foodborne bacterium linked to severe illness.
Loss of X Chromosome May Reduce Chances Of Natural Pregnancy
As more women delay parenthood, researchers are searching for better ways to assess fertility. A new study points to loss of the X chromosome as a potential indicator of declining reproductive potential.
New Study Reveals Hidden Sources Of Lead In Manila’s Air
The end of leaded gasoline was hailed as a major public health victory, but researchers warn that lead pollution remains a persistent threat in Metro Manila, driven largely by industry, waste processing and vehicle emissions.
Wastewater Monitoring Can Predict Flu Outbreaks Sooner Than Clinical Data
A study from Japan demonstrates that wastewater monitoring can accurately forecast influenza A and B outbreaks up to a week earlier than traditional surveillance.
Brain’s “Brake Gate” May Hold Key To Preventing Drug Addiction Relapse
The study shows that specific parvalbumin-positive neurons in the prefrontal cortex control cocaine-seeking behaviour and could be targeted for addiction treatment.
Warming Seas Push Japan’s Iconic Salmon North
Warming oceans, shrinking food supplies, and extreme heatwaves are pushing Japan’s iconic fish toward colder waters.
This Norovirus Breakthrough Could Accelerate Vaccine Development
Japanese researchers have developed a reverse genetics system that enables the generation and study of infectious noroviruses without the use of cultured cells.
Why High Altitudes Trigger Headaches
At the summit of Mount Fuji, researchers tracked blood flow in climbers’ brains and found that shifts in how blood moves through key arteries may hold the answer to acute mountain sickness.
