Comet 2I/Borisov is the first interstellar comet to be observed by astronomers.

The discovery may help lead to a new understanding of mitochondria’s roles in aging, disease and medical complications, the UCLA researchers said.

UCLA astronomer Bradley Hansen on how a giant exomoon hundreds of times the size of Earth might help astronomers find planets where life may thrive.

If skies are clear, viewers will be able to see the moon — approximately 240,000 miles from Earth — and its many craters in great detail.

The event is being held exactly a half century after a team led by UCLA professor Leonard Kleinrock sent the first message over the Arpanet — the precursor to today’s internet.

UCLA evolutionary biologist Blaire Van Valkenburgh links an increase in fractured teeth to a dwindling supply of the carnivores' prey.

Innovative technology improves visualization of a patient’s anatomy.

UCLA Health researchers implanted a wireless device that enables people without sight to detect motion, distinguish light and dark.

A version of the technology, set up on the roof of a home, could provide enough power overnight to charge a cell phone or to light a room with LED bulbs.

“We have never seen anything like this in the 24 years we have studied the supermassive black hole,” said UCLA professor Andrea Ghez.

UCLA engineering professor Ximin He said the design could be adapted to use other forms of energy — acoustic waves, or electronic or magnetic signals, for example.

Research shows that certain gut bacteria can respond to serotonin and drugs that influence serotonin, like anti-depressants. The biologists call this a unique form of communication between bacteria and cells.

The software provides data to help doctors diagnose and treat back pain.

The new Biodesign Hub in Los Angeles will focus on developing medical technology and digital health tools.

The advance could lead to more reliable analytical tools for biochemical laboratories and environmental monitoring.

The invention relies in part on another UCLA invention, photonic time stretch.

The approach could offer a way to manufacture more effective filters that use high-performance plastics and carbon materials.

Their findings could lead to new methods to get the body's repair enzyme to work better.

Research brief: The team developed an approach to visualizing structure called microcrystal electron diffraction, which allowed the researchers to confirm how the newly discovered molecular assembly pathway works.

Does the physicist’s theory tell the full story? A detailed analysis of a star’s orbit near supermassive black hole gives a look into how gravity behaves.

The research addresses a longstanding question: Why does the moon have so much less ice than Mercury, despite their similar surface conditions?

Sarah T. Roberts profiles the hidden workforce that monitors objectionable material on the internet, often to its own detriment

The new process creates a material that’s at least five times tougher than any glass currently available.
