Study finds that high-fiber diet may ‘rejuvenate’ cancer-fighting immune cells
Microbes in the gut can help the immune system fight cancer, and a fiber-rich diet may be key to reaping the benefits, a study in mice suggests. The immune system plays an important role in the body’s fight against cancer. At the forefront of this resistance are CD8+ killer T cells, a type of immune […]
‘Nothing but a nightmare’: A worker ant is tricked by a fake queen into killing his mother – and quickly seizes the throne
Invading parasitic ant queens trick workers in various colonies into killing and dismembering their own mothers, allowing the invaders to intervene and usurp the throne, according to a new study. The parasite appears to invade the colony and spray the reigning queen with formic acid. “The queen’s odor is erased by formic acid, instantly turning […]
The gulf separating Africa and Asia continues to pull them apart 5 million years after scientists thought they had stopped.
Researchers have found that the Gulf of Suez, which partially separates Africa and Asia, may still be expanding. Starting about 28 million years ago, the Arabian Plate separated from the African Plate, opening up what is today the Gulf of Suez. This type of rift would lead to the birth of a new ocean, but […]

The more we use AI, the more likely we are to overestimate our own abilities.
When asked to evaluate how good we are at something, we tend to get it completely wrong. This is a universal human tendency, and its effects are strongest among those with lower levels of ability. This phenomenon, called the Dunning-Kruger effect after the psychologist who first studied it, means that people who are less good […]

Once a caterpillar hatches from an egg, it spends its first few weeks of life eating as much as it physically can. It then hangs upside down from a leaf or stem and sheds its outer skin to expose the pupa. Inside, the caterpillar’s body breaks down and specialized cells called imaginal discs begin to […]
