Drug improves the sense of touch, Science study says

A new study found that a drug can temporarily improve tactile acuity by reorganizing brain activity, offering potential treatments for learning disabilities and chronic pain. The treatment involves finger stimulation with a drug, which boosts the number of neurons involved in processing tactile information.

Is there a benefit to having been vaccinated against smallpox as a child?

Researchers found that adults who received smallpox vaccinations as children showed fewer adverse reactions to diluted vaccine doses compared to those who never received the vaccine. The study's results have implications for potential future biological attacks and suggest that vaccine stocks may be more sustainable.

Breast cancer survivors have fewer heart attacks

A study of over 5,980 women aged 67 or older found that breast cancer survivors had 34% fewer hospitalizations for heart attacks than non-survivors. The protective effect increased with higher cardiac risk factors, suggesting that female hormone levels may play a role in preventing heart disease.

Astronomers find 'home from home' - 90 light years away!

A team of British, Australian and American astronomers have discovered a planet similar to Jupiter in orbit around a nearby star, 3.3 times further from its star than Earth is from the Sun. The system's long-term precision allows for the detection of true analogues to our Solar System, advancing the search for systems like our own.

Science historians ponder naming 'enemies' in science literature

Science historians argue that metaphors used in ecological science can carry misleading connotations and contribute to cultural bias. They claim that terms like 'natural enemy' are used without explanation or definition, leading to misconceptions about ecological interactions.
