Video Breakthrough DNA technology identifies 9|11 victim's remains nearly 25-years later

Nearly 25 years after the September 11th attacks, advanced DNA technology has successfully identified the remains of a victim. This breakthrough highlights the ongoing efforts to bring closure to families affected by the tragedy.

A major Alzheimer's risk gene may shrink brain cells years before symptoms

A study in mice reveals that the APOE4 Alzheimer's risk gene increases levels of a protein called Nell2, which shrinks neurons and makes memory circuits overactive years before symptoms appear—but reducing Nell2 reversed these changes, suggesting a potential early intervention route.

A hidden "on switch" in human DNA has finally been decoded

Researchers have used artificial intelligence to decode the DNA signature of a genetic "switch" called the initiator, which plays a key role in activating genes, with the model identifying this element in roughly 60% of human genes analyzed.

NASA plans to send a nuclear reactor to Mars in 2028

NASA has announced plans to send a nuclear reactor to Mars as part of a 2028 mission, advancing the agency's capabilities for sustained exploration of the Red Planet.

NASA is about to launch a powerful new eye on the universe

NASA is preparing to launch a new advanced telescope designed to enhance deep space observation capabilities, continuing its legacy of exploring the universe from above our atmosphere.

Motor neurons don't just move muscles. They may direct that motion too

Research on fruit flies reveals that motor neurons do more than simply relay signals from the brain to muscles—they actively participate in directing motion by sending feedback signals back to the brain and organizing sequences of movement.
