Graphene kills harmful bacteria “superbugs” but spares human cells

Scientists have uncovered how graphene oxide pulls off a remarkable trick: it hunts down and destroys harmful bacteria while leaving human cells completely unharmed. By targeting a molecule found only in bacterial membranes, this ultra-thin carbon-based material acts with laser-like precision—offering a powerful new alternative to traditional antibiotics. Even more exciting, it works against drug-resistant “superbugs,” promotes faster wound healing, and keeps its antibacterial strength even after repeated washing.

Scientists just found what keeps plant cells from growing out of control

Before seedlings can photosynthesize, they depend on fatty acids—and on peroxisomes to process them. Researchers discovered that the protein PEX11 not only helps these structures divide but also controls their size during early growth. When key genes were altered, peroxisomes grew abnormally large, suggesting internal vesicles normally keep them in balance. Remarkably, a yeast version of the protein fixed the problem, pointing to a deeply conserved mechanism across species.

Harvard scientists link gut bacteria to depression through hidden inflammation trigger

A gut bacterium may be quietly fueling depression through an unexpected chemical twist. Researchers found that when Morganella morganii interacts with a common pollutant, it produces a molecule that triggers inflammation—something strongly linked to depression. This finding helps explain how gut microbes can influence brain health at a molecular level. It also raises the possibility of new treatments that target the immune system rather than just the brain.

Hidden voids found in Menkaure pyramid hint at secret entrance

A fresh mystery is unfolding inside Egypt’s pyramids. Researchers have discovered two hidden air-filled voids lurking behind the smooth eastern face of the Menkaure pyramid—an area long suspected to conceal something unusual. Using advanced, non-invasive techniques like radar and ultrasound, the team pinpointed these cavities with surprising precision, lending strong support to the idea that a secret entrance may exist.

Ancient mass grave reveals how a pandemic wiped out a city 1,500 years ago

A newly confirmed mass grave in ancient Jordan offers chilling insight into one of history’s first pandemics. Hundreds of plague victims were buried within days, revealing how the Plague of Justinian devastated entire communities. The findings show that people who usually lived spread out across regions were suddenly concentrated in death. It’s a powerful reminder that pandemics don’t just spread disease—they reshape how societies live and collapse.

Scientists create plastic that destroys viruses on contact

A new virus-fighting plastic film could transform everyday surfaces into invisible defenders against disease. Instead of relying on chemicals, this flexible material is covered in microscopic pillars that physically stretch viruses until they burst, rendering them harmless. In lab tests, it destroyed or disabled about 94% of virus particles within an hour, showing impressive effectiveness.
