Planetary scientists believe they have observed waves rippling on one of Titan’s seas. The findings, presented on March 17 at the Lunar and Planetary Science Conference, describes how the Cassini spacecraft captured images of sunlight glinting off the Punga Mare, suggesting they are not reflective sunlight but waves.

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.

Named Siats meekerorum, after the man-eating monster from the Ute tribal legend, the fossil belongs to a species of giant meat eaters known as carcharodontosaurs and is the second one discovered in North America.
“This thing is gigantic,” Lindsay Zanno, a paleontologist at North Carolina State University, who discovered the species, said. “There’s simply nothing even close in this ecosystem to the size of this animal that could’ve been interpreted as an apex predator.”

The team used graphene’s mechanical “stretchability” in order to create a voltage controlled oscillator (VCO) – an electronic component that can generate an FM signal. The VCO was used to send and receive audio signals of 100 megahertz. The team used pure tones and more complex music signals to tune the VCO’s output and found that both kinds of signals could be “faithfully reproduced” by an ordinary radio receiver.

Nathan Gray, 10, from Nova Scotia, Canada, recently discovered a 600-million-year-old supernova in the galaxy PGC 61330, which lies in the constellation of Draco – beating his sister by 33 days as the youngest person to find a supernova.
Gray made the discovery on October 30 while looking at astronomical images taken by Dave Lane, who runs the Abbey Ridge Observatory (ARO) in Nova Scotia. The Royal Astronomical Society of Canada confirmed Gray’s discovery, but astronomers with the International Astronomical Union say they will need to use a larger telescope to make the finding official.

The twin inverted pulse radar (TWIPR) made by a team from the University of Southampton in England uses the same technique dolphins do to capture prey. Like dolphins, the device sends out two pulses in quick succession to cancel out background noise.

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 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.

Japan on Tuesday unveiled its biggest warship since World War II, a huge flat-top destroyer that has raised eyebrows in China and elsewhere because it bears a strong resemblance to a conventional aircraft carrier.
Some experts believe the new Japanese ship could potentially be used in the future to launch fighter jets or other aircraft that have the ability to take off vertically.
The ship, which has a flight deck that is nearly 250 meters (820 feet) long, is designed to carry up to 14 helicopters.Though the ship — dubbed "Izumo" — has been in the works since 2009, its unveiling comes as Japan and China are locked in a dispute over several small islands located between southern Japan and Taiwan. For months, ships from both countries have been conducting patrols around the isles, called the Senkaku in Japan and the Diaoyutai in China.

A fibrous dysplasia tumor has been found in the bone of a Neanderthal that is more than 120,000 years old. The world’s oldest tumor in a Neanderthal rib was part of a collection of bones, which were excavated more than 100 years ago from a site in Krapina, Croatia. They were X-rayed in the 1980s, and initially didn’t reveal the tumor. It was only when scientists took a closer look at a radiograph where a rib fragment appeared to be “burned out” did they return to the rib and subject it to higher quality scans.
