4058. Dying Sun-like stars may kick themselves through space

Dying Sun-like stars may not fade away quietly. As blobs of gas erupt unevenly from their swollen surfaces, each burst gives the star a tiny push in the opposite direction. Thousands of these random kicks could eventually break apart distant stellar pairs or, in rare cases, drive two stars into a violent collision.

4059. New quantum gravity theory links entropy, dark energy, and life

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.

4060. This food compound may help vaccines work better in older adults

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.

4061. Ancient mystery on K’gari as world’s largest sand island lakes dried up during rainy era

Ancient sediment reveals that some of K’gari’s deepest lakes vanished around 7,500 years ago, despite unusually heavy rainfall. The surprising discovery suggests changing winds and future climate shifts could threaten the sacred lakes known as the Eyes of K’gari.

4062. New molecular map reveals how the flu virus hijacks human cells

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.

4063. A hidden “switch-off” signal could predict solar storms seven years early

A newly discovered turning point in the Sun’s 11-year cycle could allow scientists to predict future solar activity years earlier than before. At this “switch-off” point, the most violent space weather abruptly ends, and the remaining number of sunspots offers clues about the next cycle’s strength. Early projections suggest Solar Cycle 26 may be moderate, but a clearer forecast is expected in about two years.

4064. Astronomers find the first atmosphere on a rocky world in the habitable zone

Astronomers have found the first confirmed atmosphere around a rocky planet in another star’s habitable zone. The planet, LHS 1140 b, revealed its atmosphere through helium slowly leaking into space. Located 48 light-years away, the world may have preserved its atmosphere for billions of years, making it a promising target in the search for potentially habitable planets.

4065. Watching too much TV in midlife may shrink the brain

Watching television very often in midlife may be linked to troubling brain changes decades later. In a study of about 1,700 adults, frequent TV viewers later showed smaller brain regions involved in memory, decision-making, and visual processing, along with more signs of damage in the brain’s white matter. Surprisingly, sitting itself did not appear to be the main issue, since people who spent long hours seated at mentally engaging jobs often showed healthier brain patterns.

4066. Ancient DNA reveals a chilling secret at China’s 4,000-year-old Shimao city

Ancient DNA from China’s vast 4,000-year-old Shimao settlement is revealing how one of East Asia’s earliest complex societies was organized. Researchers found that its people were largely descended from local Yellow River farming communities, but also had genetic ties to distant southern and steppe populations, pointing to extensive prehistoric contact.

4067. Scientists found mystery bacteria inside one of the ocean’s most elusive whales

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.
