Lasers are used in a range of everyday devices, harnessing the power of light molecules, photons, - lined up to form highly concentrated beams of light - to perform now common tasks such as scanning barcodes and removing tattoos.
Tsukuba, Japan - Cooked, fresh, sun-dried, or juiced, whichever way you prefer them, tomatoes are arguably one of the most versatile fruits on the planet--and yes, despite mainly being used in savory dishes, tomatoes really are a fruit.
In recent years, the microbiota -- the community of bacteria and other microorganisms that live on and in the human body -- has captured the attention of scientists and the public, in part because it's become easier to study. It has been linked to many aspects of human health.
Laboratory research and analysis of epidemiological data by Silvia Corvera, MD, and Tiffany Moore Simas, MD, MPH, MEd, and colleagues show that low levels of a protein commonly seen in screening tests for chromosomal disorders during the first trimester of pregnancy is associated with adipose tissue remodeling, glucose resistance and gestational diabetes mellitus in pregnant women.
New antennas so thin that they can be sprayed into place are also robust enough to provide a strong signal at bandwidths that will be used by fifth-generation (5G) mobile devices. Performance results for the antennas, which are made from a new type of two-dimensional material called MXene, were recently reported by researchers at Drexel University and could have rammifications for mobile, wearable and connected "internet of things" technology.
So, you need a robot that climbs stairs. What shape should that robot be? Should it have two legs, like a person? Or six, like an ant?
Choosing the right shape will be vital for your robot's ability to traverse a particular terrain. And it's impossible to build and test every potential form. But now an MIT-developed system makes it possible to simulate them and determine which design works best.
Baltimore, MD--Human activity endangers coral health around the world. A new algal threat is taking advantage of coral's already precarious situation in the Caribbean and making it even harder for reef ecosystems to grow.
Just-published research in Scientific Reports details how an aggressive, golden-brown, crust-like alga is rapidly overgrowing shallow reefs, taking the place of coral that was damaged by extreme storms and exacerbating the damage caused by ocean acidification, disease, pollution, and bleaching.
Magnesium batteries have long been considered a potentially safer and less expensive alternative to lithium-ion batteries, but previous versions have been severely limited in the power they delivered.
Hackensack, N.J., November 30, 2020 - A novel therapy designed to help stimulate the body's immune system response against cancer appears to be safe to use as alone or in combination with immune checkpoint inhibitors, according to an early phase clinical trial led by Martin Gutierrez, M.D., chief medical oncologist of the thoracic division at Hackensack University Medical Center's John Theurer Cancer Center, a member of the Georgetown Lombardi Comprehensive Cancer Center Consortium.
A new study led by researchers at the Johns Hopkins Bloomberg School of Public Health and the Federal Reserve Board of Governors found that Medicare beneficiaries who go on to be diagnosed with dementia are more likely to miss payments on bills as early as six years before a clinical diagnosis.
The study also found that beneficiaries diagnosed with dementia who had a lower educational status missed payments on bills beginning as early as seven years before a clinical diagnosis as compared to 2.5 years prior to a diagnosis for beneficiaries with higher educational status.
A new study demonstrates that grammar is evident and widespread in a system of communication based on reciprocal, tactile interaction, thus reinforcing the notion that if one linguistic channel, such as hearing, or vision, is unavailable, structures will find another way to create formal categories. There are thousands of people across the US and all over the world who are DeafBlind. Very little is known about the diverse ways they use and acquire language, and what effects those processes have on the structure of language itself.
PRINCETON, N.J.--The alarming rate at which Covid-19 has killed Black Americans has highlighted the deeply embedded racial disparities in the U.S. health care system.
Princeton researchers now report that low-income Black households also experienced greater job loss, more food and medicine insecurity, and higher indebtedness in the early months of the pandemic compared to white or Latinx low-income households.
To develop effective therapeutics against pathogens, scientists need to first uncover how they attack host cells. An efficient way to conduct these investigations on an extensive scale is through high-speed screening tests called assays.
Magnets often harbour hidden beauty. Take a simple fridge magnet: Somewhat counterintuitively, it is 'sticky' on one side but not the other. The secret lies in the way the magnetisation is arranged in a well-defined pattern within the material. More intricate magnetization textures are at the heart of many modern technologies, such as hard disk drives.
Elders are more respected in Japan and China and not so much in more individualistic nations like the United States and Germany, say Michigan State University researchers who conclude in a pair of studies that age bias varies among countries and even states.
