- July 30 (UPI) -- Invasive all-female weevils pass along epigenetic changes to their offspring, helping them adapt to new environs, according to a new study. Across most of the animal kingdom, an organism's ability to adapt and evolve is largely ... [Read More]


- Cat genomes are more similar to ours than those of mice and dogs, yet researchers say felines are underutilized in genetic studies of disease Cats have genomes that are structured in much the same way that humans’ are, and an article published ... [Read More]

- For the first time ever, astronomers have directly detected light from behind a supermassive black hole . The discovery proves Albert Einstein's theory of general relativity was right — again . Using the European Space Agency 's XMM-Newton and ... [Read More]


- A new batch of research shows that clay, not water, may be the source of bright spots under Mars’ South Pole. Water is the key ingredient for life on Earth, which is why scientists hoping to find aliens on other worlds are particularly interested in its presence. A team of researchers made a huge splash on this front in 2018 by suggesting that radar observations of bright patches under the southern polar cap of Mars were hidden lakes that could potentially provide a habitat for modern Martian microbes, according to . But a trio of new studies throws cold water on these hypothetical ... [Read More]


- Symptoms for early COVID-19 infection differ among age groups and between men and women, new research has found. These differences are most notable between younger age groups (16-59 years) compared to older age groups (60->80 years), and men have ... [Read More]

- A Covid outbreak first discovered in the Chinese city of Nanjing has spread to five provinces and Beijing, with state media calling it the most extensive contagion after Wuhan. Almost 200 people have been infected since the virus was first detected ... [Read More]

- Six passengers sailing on Royal Caribbean International's Adventure of the Seas, which departed from Nassau Saturday, have tested positive for COVID-19, Lyan Sierra-Caro, spokesperson for Royal Caribbean, confirmed to USA TODAY Friday. All are ... [Read More]


- The possible existence of the sunken continent “Icelandia” could help scientists find other hidden masses under the sea. A vast sunken continent called “Icelandia” may exist under the North Atlantic Ocean, a finding that, if proven, could ... [Read More]


- James Meador, an independent researcher at the California Institute of Technology, has found evidence that suggests the Apollo 11 ascent stage may still be orbiting the moon. He has written a paper outlining his research and findings and has posted it on the arXiv preprint server. In 1969, NASA astronauts Neil Armstrong and Buzz Aldrin made history when they landed a craft successfully on the moon . After more than 21 hours on the surface, the astronauts blasted off the surface in a part of the Eagle lander called the ascent stage. They soon thereafter rendezvoused with Michael Collins in ...

- The company has bounced back from a mid-May launch failure. Rocket Lab is back in business. The company's Electron rocket launched a small satellite for the U.S. military early Thursday morning (July 29), acing its first mission since suffering a ... [Read More]

- These bacteria could contribute to a healthy gut and, in turn, healthy aging. People who live to age 100 and beyond may have special gut bacteria that help ward off infections, according to a new study from Japan. The results suggest that these ... [Read More]

- Scientist Dr Lauren Smith explains why Sylvester Stallone's dunderheaded supervillain would struggle with shrivelling eyes in the real world – and would have no desire to munch on humans. Just when you thought it was safe to go back in the water, ... [Read More]

- SLEEPING BEAR DUNES NATIONAL LAKESHORE — The divers leaned back from the edge of the boat and splashed into water, bobbing up for a moment before dropping down to a world just a few miles off the northern Michigan coast — and worlds away from ... [Read More]

- People with compromised immune systems and the unvaccinated make up a high percentage of patients who end up in the hospital. Since early July, the average number of coronavirus cases in New York City has quadrupled, from about 250 to more than 1,000 per day, as the more contagious variant Delta has spread. Hospitalizations are also rising, though not as quickly, thanks to vaccinations and improved treatments. Still, hospitalizations are up 90 percent since July 4, and more than 300 people are now hospitalized in New York City with Covid-19. They are, for the most part, unvaccinated, or ... [Read More]


- Electrical engineers from the UCLA Samueli School of Engineering have developed a more efficient way of converting light from one wavelength to another, opening the door for improvements in the performance of imaging, sensing, and communication systems. Mona Jarrahi, professor of electrical and computer engineering at UCLA Samueli, led the Nature Communications -published research. Finding an efficient way to convert wavelengths of light is crucial to the improvement of many imaging and sensing technologies. For example, converting incoming light into terahertz wavelengths enables imaging ... [Read More]

- Combines integration and performance in one compact, low-power device supported by Microchip’s widely deployed IEEE 1588 Precision Time Protocol (PTP) and synchronization algorithm software modules CHANDLER, Ariz.-(BUSINESS WIRE)-5G technology requires time sources to be synchronized throughout a packet-switched network ten times more accurately than 4G requirements. Microchip Technology Inc. (Nasdaq: MCHP) now makes it possible to achieve 5G performance with the first single-chip, highly integrated, low-power, multi-channel integrated circuit (IC) coupled with the company’s widely ...

- In late December 2019, a novel coronavirus was first reported in Wuhan, China, which showed high infectivity and caused pneumonia-like symptoms. Scientists later identified this RNA virus as the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus. Owing to rapid mutations, the continual emergence of several SARS-CoV-2 variants have been reported, among which some are regarded to be variants of concern (VOC), e.g., Alpha, Beta, and Delta. Other variants are known as variants of interests (VOI), e.g., Eta, Kappa, Lambda, and Iota. As a result, researchers keep an eye on the ... [Read More]

- Paleontologists have uncovered an enormous fossil graveyard of squiggly, alien-like Jurassic sea creatures beneath a limestone quarry in the UK's Cotswolds region. The fossil find includes perhaps tens of thousands of marine invertebrates called echinoderms - meaning "hedgehog skin" in Greek, and including the ancient ancestors of modern starfish, sea cucumbers , sea urchins and frilly-limbed sea lilies - immaculately preserved at all stages of their life cycles, the researchers said in a statement . But right when things were booming, the thriving seabed community met a cataclysmic end; a ... [Read More]

- Mutations that make a virus more transmissible are only part of the equation If researchers were predicting which coronavirus variant would take over the world, the Delta variant would not have been their first guess. But since its first appearance in India in December 2020, the highly contagious variant has become the predominant strain of the virus, accounting for more than 90 percent of new COVID cases in the U.S. Delta’s emergence has caused a number of countries to reinstate travel and mask restrictions that had been loosened as vaccination rates rose. Although the vaccines appear ... [Read More]
