Hanging in the Balance

The Moon appears half-illuminated in this photo captured by the Artemis II crew on flight day 6. The terminator – the difference between light and darkness – provides a stark contrast and even greater perspective of the Moon’s rocky, uneven, and otherworldly surface features. The near side, which is what we can see from Earth, […]

A rare interstellar visitor triggered a SETI search for alien technology

SETI scientists searched the interstellar object 3I/ATLAS for radio signals that could indicate extraterrestrial technology but found nothing beyond human-made interference. Even so, the rapid-response observations helped confirm the object's natural origin and showcased how future interstellar visitors can be investigated for signs of intelligent life.

Scientists finally solved how H5N1 bird flu hid in dairy cows

Researchers uncovered why H5N1 bird flu attacks cows’ udders instead of their lungs: the virus’s preferred receptors are concentrated in mammary tissue. The breakthrough could help scientists predict future bird flu jumps and spot unusual infections before they spread widely.

Hidden bird species discovered in Japan after DNA reveals a stunning secret

A bird long thought to be a single rare species in Japan has turned out to be two. Scientists discovered that the elusive Ijima’s Leaf Warbler and a newly identified Tokara Leaf Warbler look almost identical, but their DNA and songs reveal they are distinct species. The finding marks Japan’s first new bird species discovery in more than 40 years and highlights how modern genetic tools are uncovering hidden biodiversity that would otherwise go unnoticed.

Scientists just discovered how queen bees are really made

For decades, scientists thought royal jelly was the secret ingredient that turned an ordinary honeybee larva into a queen. New research reveals the process is far more remarkable: young worker bees create special “royal cribs” made from customized wax, carefully regulate warmth and humidity, and dedicate entire teams of attendants to raising future queens.
