LEDs are commonly found in TV screens, computer monitors and light bulbs. While the light sources are known to be small, scientists have recently built the thinnest possible LEDS using tungsten diselenide. The nano-sized LEDs are arguably stronger and more energy efficient than their thicker counterparts.

A biological clock capable of determining how old different human tissues and cells are has been discovered by a team of researchers from the University of California Los Angeles.
"To fight aging, we first need an objective way of measuring it. Pinpointing a set of biomarkers that keeps time throughout the body has been a four-year challenge," Steve Horvath, a professor of human genetics at the David Geffen School of Medicine at UCLA and of biostatistics at the UCLA Fielding School of Public Health said in a statement. "My goal in inventing this clock is to help scientists improve their understanding of what speeds up and slows down the human aging process."

Scientists at the University of Texas looked at the interactions between bacteria in 3D-printed environments to better understand what makes some microbes resistant to antibiotics, something health officials have been warning us about for a long time. They used high-precision lasers to print multiple two-dimensional images, using a chip modified from a digital movie projector, onto a layer of flexible gelatin where bacteria were growing. As layers of protein were added to the gelatin, which contains photosensitive molecules that become aroused and bond together after being hit with a laser, they formed a tiny encasing around the bacteria.

An 11-year-old Colorado boy may have found a way to literally make a beer that’s out of this world.
Michal Bodzianowski, a sixth grader at Douglas County's STEM School and Academy in Highlands Ranch, Colo., recently won a national competition where his beer-making experiment will be flown to the International Space Station.

Scientists from the Korea Advanced Institute of Science and Technology in Daejeon, South Korea, have developed a “jellyfish terminator” robot set out to detect the marine coelenterate and kill it.
“Once jellyfish are detected using a camera, the jellyfish removal scenario is started with generating efficient path to remove the jellyfish,” team leader Professor Myung Hyun wrote in the journal Advances in Intelligent Systems and Computing. “Finally, the jellyfish is sliced up with the grid installed underneath the JEROS by following the generated path.”

Scientists say they used the pandemic as a “natural experiment” to discover how the body’s immune system builds resistance to the flu. The research, published in the journal Nature Medicine, showed how certain immune cells helped some avoid the severe illness.

Found in the Ocucaje Desert in southern Peru, the fossils belong to a group called Achaeocetes, or ancient whales, that possess both land and sea-dwelling characteristics. Over time, the ancient land animals adapted to water environments where their legs became fin-like and their bodies began to resemble modern sea mammals like dolphins and whales.
