Light

A novel platinum-enhanced, light-activated compound kills cancer cells in a unique way without requiring oxygen, overcoming a limitation with existing light-based cancer therapies. It paves the way for the next generation of anti-cancer drugs.

Generally speaking, if you want to grab sharp images of fast movements such as molecular interactions, you're going to need a super-expensive rig. Researchers have developed a system built using projector tech that could significantly cut the cost.

Researchers have developed a novel material using nanocrystals that converts light into a mechanical force able to lift 1,000 times its mass, opening the door for wireless, remote-controlled systems that operate without heat or electricity.

When heading into the wilds for a camping trip, space in a backpack is at a premium. Oukitel has lightened the load by incorporating a powerful camp light into its latest rugged smartphone, allowing outdoors enthusiasts to leave the lantern at home.

While GPS can be used to determine one's geographical coordinates on land, such is not the case underwater. Scientists have developed an alternative, however, in the form of a system that analyzes the manner in which sunlight is polarized by water.

Back at CES 2023, smart telescope maker Unistellar launched a new model that could digitally remove light pollution from cities to give users a clear view of the stars. Now the company has improved on the formula with its new Deep Dark Technology.

Traffic is among the biggest sources of air pollution, but what if the very roads they drive on could help clear the air? Engineers in Korea have now demonstrated that photocatalytic concrete can help reduce pollution in tunnels.

Astronomers have witnessed an apocalypse from across the galaxy, as a planet crashed into its star. It’s an event long assumed to happen in many star systems – including our own someday – but this is the first time it’s ever been seen directly.

Astronomers have detected a supermassive black hole ripping a passing star to shreds. Not only was this closer to Earth than ever seen before, but its location and light emissions were unusual, hinting at a large unseen population of these events.

A team of researchers led by Northwestern University and the University of Texas at Austin (UT) have developed a novel graphene heart implant that’s about the thickness of a strand of hair and monitors and corrects abnormal heart rhythms using light.

The squid’s color-changing abilities have fascinated scientists for decades. Now, researchers have created a new squid-inspired artificial skin that can withstand extreme cold and kill microbes, opening the door to a range of potential uses.

One in five older Americans have been diagnosed with heart disease, and age-related cardiovascular decline is the biggest killer of adults over 65. Now, further research into light therapy opens the door to staving off this deadly condition.
