Science News: Recent scientific discoveries and expert analysis

Researchers have documented orcas dropping prey and other marine life in front of humans, as if offering us food. The orcas' motives are uncertain, but the sharing behavior could be an attempt at a cross-species relationship or manipulation.

In a first, researchers have sequenced the complete genome of a man from ancient Egypt, and the results reveal that he had genetic ties with Mesopotamian DNA.

Astronomers have spotted an alien planet orbiting so closely to its home star, the planet's magnetic field is triggering massive solar flares to erupt. This is the first time a planet has been seen influencing its host star.

A possible new "jellyfish" galaxy discovered by the James Webb Space Telescope could deepen our understanding of galaxy evolution and star formation.

An explosion captured in a new image could help astronomers to better understand the "standard candles" at the center of a major cosmological mystery.

Researchers have identified ways in which chemotherapy can damage healthy cells and found that some drugs can add decades of "age" to otherwise normal blood cells.

A study suggests that carefully controlled electrical stimulation of the brain may improve math skills, most significantly in people with weaker connections in a specific part of the brain.

Astronomers have spotted another never-before-seen "nova" blaze to life in the night sky. This may be the first time that simultaneous stellar explosions have been visible to the naked eye in recorded history.

Lake Superior Zoo in Minnesota announced it has given a brown bear the world's largest dental crown, with the bear now sporting a silver-colored metal canine

The ALMA radio telescope array in the Atacama Desert temporarily halted operations after a rare snowfall blanketed the base camp last week.

Astronomers have discovered the strange dance that leads to the creation of rare "double hot Jupiters" in binary star systems that are "just right."

A second transplant patient also became infected, leading their doctors to surmise that their new kidneys were likely to blame.

In a recent contest, teams of researchers competed to see who could train an AI model to best pilot a spaceship. The results suggest that an era of autonomous space exploration may be closer than we think.

The Rubin Observatory released its first magnificent images of the cosmos on Monday, June 23 — and included a special asteroid bonus.

Scientists say they captured 3D images of a new organelle they're calling a "hemifusome," which may be a recycling center in human cells.

The bronze artifacts may have served as coffin handles for a burial in what is now Israel, but the true nature of the find remains unclear.

The Wandan mud volcano has erupted in Taiwan, sending bubbling mud shooting into the air as locals ignite ejected gases with burning rags.

Free-floating DNA carrying cancerous mutations was detected in blood three years before any other signs of cancer appeared. If approved as a test, doctors might detect cancers sooner and treat them before they spread.

Bats found near orchards harbor pathogens that could be passed to livestock or humans.

NASA's new "CODEX" telescope has snapped its first photos of the sun's outer atmosphere, revealing previously imperceptible changes that could help scientists better predict potentially dangerous space weather events.
