The First 24 Hours of A Viral Infection May Help Determine Its Outcome
A Japanese study in mice suggests that differences in the body’s antiviral response emerge within a day of infection, and may help explain why the same virus affects individuals so differently.
For Some Disaster Survivors, The Trauma Can Last Over A Decade
A 15-year study of Great East Japan Earthquake survivors found that worsening post-traumatic stress symptoms during the first two years were strongly linked to persistent symptoms years later.
This New Tech Could Help The Ocean Absorb More CO₂
The technology can extract dissolved carbon from seawater and lock it away as stable minerals, potentially enabling long-term carbon storage with lower energy use.
Climate Change Is Making Himalayan Rivers Change Course Faster
Researchers analysing four decades of satellite data found Himalayan rivers are changing course more rapidly as climate warming weakens riverbanks, with implications for water security and communities downstream.
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.
