If ARM doesn’t prove it can be a level playing field in Nvidia’s ownership, customers will defect to alternatives.
Plastic pollution has become one of the most pressing environmental issues now that the rapidly increased production of disposable plastic products is far beyond the world’s capacity for recycling and upcycling waste plastics. Although recent studies have provided a few catalytic strategies for producing value-added fuel and chemical products from polyethylene (PE) waste, the kinetic rates and/or selectivities are unsatisfactory, even with extended processing time (24 h) and high temperatures (280°C). This work reports a liquid-phase catalytic hydrogenolysis process that highly efficiently converts high-density PE to jet-fuel-and lubricant-range hydrocarbons under relatively mild conditions. The application of this efficient liquid-phase catalytic hydrogenolysis process could provide a promising approach for selectively producing high-value products, such as lubricants, from waste PE and other polyolefin polymers.
Bruchsal/Munich, 17 May 2021 – Today, Volocopter, the pioneer of urban air mobility (UAM), unveiled its newest aircraft, VoloConnect, at EBACE Connect. This electric vertical take-off and landing aircraft (eVTOL) is designed to connect suburbs to cities and complements the company’s existing family of aircraft for the intra-city mission. VoloConnect’s distinctive hybrid lift and push design is expected to achieve certification within the next 5 years.
With the capacity to travel longer distances, VoloConnect joins Volocopter’s aircraft family and extends the company’s UAM ecosystem coverage to the suburbs. The new aircraft will be seamlessly integrated into Volocopter’s existing portfolio of UAM ecosystem solutions: VoloDrone, VoloCity, VoloPort, and the digital platform, VoloIQ.
Conditions like recurrent miscarriage, preeclampsia, preterm birth and stillbirth are affected by the female’s immune response in ways that the partner’s sperm contribute to.
Sperm are generally viewed as having just one action in reproduction—to fertilize the female’s egg—but studies at the University of Adelaide are overturning that view.
Published in Nature Research journal Communications Biology, new research shows that sperm also deliver signals directly to the female reproductive tissues to increase the chances of conception.
Robinson Research Institute’s Professor Sarah Robertson, who led the project, said: This research is the first to show that the female immune response is persuaded by signals in sperm to allow the male partner to fertilize her eggs and conceive a pregnancy.
“This was a short-term experiment, just eight weeks,” Liu said. “In people, obesity doesn’t occur overnight or even in eight weeks. People have a suboptimal lifestyle for 20, 30 years before they become obese. It’s possible that if you have Western diet for so long, you cross a point of no return and your Paneth cells don’t recover even if you change your diet. We’d need to do more research before we can say whether this process is reversible in people.”
Eating a Western diet impairs the immune system in the gut in ways that could increase risk of infection and inflammatory bowel disease, according to a study from researchers at Washington University School of Medicine in St. Louis and Cleveland Clinic.
The study, in mice and people, showed that a diet high in sugar and fat causes damage to Paneth cells, immune cells in the gut that help keep inflammation in check. When Paneth cells aren’t functioning properly, the gut immune system is excessively prone to inflammation, putting people at risk of inflammatory bowel disease and undermining effective control of disease-causing microbes. The findings, published today (May 18, 2021) in Cell Host & Microbe, open up new approaches to regulating gut immunity by restoring normal Paneth cell function.
“Inflammatory bowel disease has historically been a problem primarily in Western countries such as the U.S., but it’s becoming more common globally as more and more people adopt Western lifestyles,” said lead author Ta-Chiang Liu, MD, PhD, an associate professor of pathology & immunology at Washington University. “Our research showed that long-term consumption of a Western-style diet high in fat and sugar impairs the function of immune cells in the gut in ways that could promote inflammatory bowel disease or increase the risk of intestinal infections.”
Even as a chip shortage is causing trouble for all sorts of industries, the semiconductor field is entering a surprising new era of creativity, from industry giants to innovative start-ups seeing a spike in funding from venture capitalists that traditionally avoided chip makers.
While a variety of industries struggle with supplies, semiconductor experts say there are plenty of new ideas and, most surprising, start-ups.
The vehicle became stuck multiple times and repeatedly drove away when roadside assistance approached.
At the time the proposed planet signal is strongest, stellar activity on the surface of the star was Also strong, says Lubin. Thus, he notes, the signal associated with the planet can be explained by activity emanating from stellar activity instead of from the telltale periodic tug on Barnard’s Star from a putative super-earth.
As I noted here previously, Barnard’s Star, which lies only 6 light years away in Ophiuchus, has long fascinated astronomers both due to its proximity to Earth and the fact that it has the largest apparent motion across our line of sight as any known stellar object. In the 105 years since its discovery by astronomer E.E. Barnard, it is the nearest star to our own Sun in the Northern Celestial Hemisphere, the authors note.
One of the more infamous claims of planets around barnard’s star came in in 1963, when Swarthmore College astronomer Peter van de Kamp announced that he had detected a planet using Swarthmore’s 24-inch refractor at Sproul Observatory. Van de Kamp later updated his findings three more times, proposing a second planet in the system with periods of 12 and 20 years, respectively, the authors note.
Giving COVID survivors just one dose of the vaccine could help end the pandemic faster In South Korea, an analysis that included more than 500000 people age 60 and older found that the Pfizer vaccine was 89% effective in preventing infection just two weeks after the first shot. AstraZeneca’s vaccine, which has not been authorized for emergency use in the U.S., was found to be 86% effective in that same time period. Again, that’s after a single dose, and it’s regardless of prior COVID history.
Commentary: Getting a second dose of Pfizer or Moderna’s coronavirus vaccine might not be necessary for COVID survivors.
Dr. Thomas Lovejoy, is an innovative conservation biologist, who is Founder and President of the non-profit Amazon Biodiversity Center, the renowned Biological Dynamics of Forest Fragments Project, and the person who coined the term “biological diversity”.
Dr. Lovejoy currently serves as Professor in the department of Environmental Science and Policy at George Mason University, and as a senior fellow at the United Nations Foundation based in Washington, DC.
Dr. Lovejoy has also served as the World Bank’s chief biodiversity advisor and the lead specialist for environment for Latin America and the Caribbean, the first Biodiversity Chair of the H. John Heinz III Center for Science, Economics and the Environment, President of the Heinz Center, and chair of the Scientific Technical Advisory Panel (STAP) for the Global Environment Facility (GEF), the multibillion-dollar funding mechanism for developing countries in support of their obligations under international environmental conventions.
Spanning the political spectrum, Dr. Lovejoy has served on science and environmental councils under the Reagan, Bush, and Clinton administrations. At the core of these many influential positions are seminal ideas, which have formed and strengthened the field of conservation biology.
