Scientists studying decades of pygmy sperm whale strandings have uncovered three previously unknown types of Helicobacter bacteria hiding in the animals’ stomachs. All four infected whales showed serious digestive damage, including inflammation, ulcers, scarring, and parasite infestations, although the bacteria were not confirmed as the cause of death.
Scientists uncovered how influenza A commandeers human cells, including a surprising strategy that dissolves tiny structures in the nucleus and releases proteins the virus may use to reproduce. The detailed molecular map could reveal new drug targets and help researchers study dangerous flu strains such as H5N1.
A naturally occurring compound found in foods such as wheat germ, mushrooms, and aged cheese may help older adults build stronger protection after vaccination. In a small pilot trial, researchers gave spermidine supplements to adults over 65 following their third COVID-19 vaccine dose. The biggest improvements appeared among people whose immune systems initially responded poorly, with higher antibody levels and stronger activity against several variants.
Storm surges up to 4ft are possible along parts of the Louisiana and Mississippi coasts, officials say.
A new theoretical study offers a possible explanation for how the Universe can grow more complex without violating the second law of thermodynamics. Using a quantum gravity framework called Gravity from Entropy, mathematician Ginestra Bianconi found that the Universe’s total entropy may rise as space expands, even while entropy within each unit of volume falls. That decline could leave room for galaxies, stars, planets, and life to form locally amid an overall increase in cosmic entropy.
Scientists have developed a fully human antibody that halted the growth and spread of aggressive prostate cancer in preclinical research. Although more testing is needed, the drug’s unusual mechanism could open the door to a safer new treatment for advanced cancer.
The furry bodies of UK bumblebees are specially adapted for cold weather - making heatwaves a struggle.
