A team led by a Baylor University researcher has published a breakthrough article that provides a better understanding of the dynamic process by which sunlight-induced DNA damage is recognized by the molecular repair machinery in cells as needing repair.
Today, large-scale communication satellite constellations, also known as megaconstellations, have been more and more popular. OneWeb launched the first batch of satellites of an initial 650-satellite constellation in February 2019, and SpaceX also launched the first batch of its 12,000-satellite constellation in May 2019. On July 8, Amazon also filed an application with the FCC for its planned satellite constellation with 3,236 satellites. These satellite constellations are expected to be a game changer by realizing the worldwide satellite Internet service.
An automated system developed by MIT researchers designs and 3-D prints complex robotic parts called actuators that are optimized according to an enormous number of specifications. In short, the system does automatically what is virtually impossible for humans to do by hand.
The tobacco industry’s court-ordered anti-smoking advertisements reached just 40.6% of U.S. adults and 50.5% of current smokers in 2018, according to new research from The University of Texas MD Anderson Cancer Center. Exposure to the advertisements was even lower among certain ethnic and socioeconomic subgroups historically targeted by tobacco industry marketing.
Scientists have known insects experience something like pain since 2003, but new research published today from Associate Professor Greg Neely and colleagues at the University of Sydney proves for the first time that insects also experience chronic pain that lasts long after an initial injury has healed.
Scientists at Hokkaido University and Hiroshima University have found that green brittle stars with five arms show a different "pumping" movement pattern than those with six arms. Using a mathematical model, they have shown that such movements can be coordinated by the flow of internal body fluid alone, rather than neuronal activity. The study was published in Scientific Reports.
A particular kind of elementary particle, the Weyl fermions, were first discovered a few years ago. Their specialty: they move through a material in a well ordered manner that practically never lets them collide with each other and is thus very energy efficient. This opens up intriguing possibilities for the electronics of the future. Up to now, Weyl fermions had only been found in certain non-magnetic materials.
Infrared imagery from NASA's Aqua satellite shows that Tropical Storm Barry doesn't look like a typical strong tropical cyclone. Imagery revealed that Barry is elongated and the strongest storms were south of it's stretched out center of circulation.
Warnings and Watches
HOUSTON - (July 12, 2019) - The ever-more-humble carbon nanotube may be just the device to make solar panels - and anything else that loses energy through heat - far more efficient.
Rice University scientists are designing arrays of aligned single-wall carbon nanotubes to channel mid-infrared radiation (aka heat) and greatly raise the efficiency of solar energy systems.
Gururaj Naik and Junichiro Kono of Rice's Brown School of Engineering introduced their technology in ACS Photonics.
Rush University Medical Center researchers have proposed a rating system that standardizes and combines data from five leading hospital rating systems into an easy-to-understand composite score of one to 10 that will help guide consumer's hospitals choice.
AI algorithms can now more accurately detect depressed mood using the sound of your voice, according to new research by University of Alberta computing scientists.
PITTSBURGH, July 12, 2019 - Living-donor liver transplant offers numerous advantages over deceased-donor transplant, including better three-year survival rates for patients and lower costs, according to new research from the UPMC Thomas E. Starzl Transplantation Institute and the University of Pittsburgh School of Medicine.
As the nation continues to get more diverse, it's common for immigrant populations in the United States to identify with two or more cultures at the same time.
In a new article published in Lingua, M. Sidury Christiansen argues for a redefinition of how we see transnationalism or the movement of people, ideas and capital across national borders.
Through her research, she argues that technology use or the way people engage with each other through technology disrupts traditional notions of homeland and host-land.
DURHAM, N.C. - New data from a two-year Duke Health trial suggests when it comes to cutting your risk for killer ailments such as diabetes and heart disease, there's always room for improvement.
In adults already at a healthy weight or carrying just a few extra pounds, cutting around 300 calories a day significantly improved already good levels of cholesterol, blood pressure, blood sugar and other markers. The findings of the randomized, controlled trial of 218 adults under age 50 are described in a July 11 article in the journal The Lancet Diabetes & Endocrinology.
While researchers have a basic understanding of how primary cancer cells grow, less is known about metastasis, the deadly process by which cancers spread. A team led by Dr. Paul Krebsbach, dean of UCLA's School of Dentistry and professor of periodontics, has found that mEAK-7, a gene they discovered last year, may play a significant role in cancer metastasis, at least in lung cancers.
