A mysterious star system just 16 light-years away may be hiding habitable planets

Astronomers have solved a 170-year-old planetary mystery in a nearby two-star system, discovering that a mysterious wobble was caused by stellar activity rather than a giant planet. Although Jupiter-sized worlds have been ruled out in key regions, smaller, potentially habitable planets could still be waiting to be discovered just 16 light-years from Earth.

Scientists discover the immune system’s hidden sense of touch

Scientists at McGill University have discovered a surprising new ability of immune cells that could change how we understand long-term immunity. Researchers found that T cells can actually sense how stiff their surrounding tissues are, using these physical signals to help determine whether they develop into long-lasting memory cells that protect against future infections.

Scientists discover a hidden messaging system deep inside the brain

A tiny region deep within the brain has surprised scientists by revealing a remarkably sophisticated communication system. Previously thought to broadcast the same chemical signal throughout the brain, this region actually sends targeted messages that help control learning, attention, and behavior, according to new research in mice.

WHO and Switzerland launch global BioHub for pathogen storage, sharing and analysis

The World Health Organization (WHO) and the Swiss Confederation today signed a Memorandum of Understanding to launch the first WHO BioHub Facility as part of the WHO BioHub System, which was announced in November 2020. This facility will enhance the rapid sharing of viruses and other pathogens between laboratories and partners globally. Based in Spiez, Switzerland, the facility will serve as a centre for the safe receipt, sequencing, storage and preparation of biological materials for distribution to other laboratories, in order to inform risk assessments, and sustain global preparedness again

DNA recording system reveals how a single cell becomes a body

Scientists have traced the development of a mouse embryo from its first two cells to the formation of organs, using a remarkable DNA recording system that reveals the family history of individual cells. Their findings uncover how different cell types emerge on their own schedules and could help explain what goes wrong in birth defects, genetic disorders, and cancer.

The eye has a hidden cleanup system scientists never knew existed

Scientists have discovered a hidden cleanup system at the back of the eye that drains fluid and waste through a previously unknown pathway. The surprising finding, demonstrated in mice, could open the door to new treatments for glaucoma, macular degeneration, and other causes of blindness.
