A fluid phenomenon seen daily in kitchens has been found to exhibit unexpected behavior.
The low oscillation frequency of spin waves in chromium trichloride enables researchers to explore this antiferromagnet’s rich properties with standard laboratory equipment.
Nan Zhong says his hands-off parenting style helped his son, Stanley Zhong, become a high-achieving student and Google software engineer at age 18. Here’s why.
Tuberculosis can advance rapidly in young children, creating an “urgent situation” after hundreds were potentially exposed at a YMCA day-care facility.
Researchers at the Francis Crick Institute and Aalborg University in Copenhagen have shown that changes can be detected in blood tests up to eight years before a diagnosis of Crohn’s disease and up to three years before a diagnosis of ulcerative colitis.
This means the beginnings of inflammatory bowel diseases start a long time before symptoms occur, and in the future may provide an opportunity for doctors to take preventative action before symptoms begin, or prescribe medication when it will be most effective.
Crohn’s disease and ulcerative colitis are collectively known as inflammatory bowel diseases (IBD). They are incurable conditions which involve excessive inflammation in the gut, leading to symptoms like abdominal pain and diarrhea. Early diagnosis and treatment are key to improving outcomes, but nearly a quarter of the 25,000 people diagnosed each year in the UK wait over a year.
The way we interact with technology will “completely change” before the decade is out, according to the billionaire Microsoft cofounder.
If recent warnings of a stalemate war between Ukraine and Russia come to fruition, along with the West’s absent resolution for Ukraine’s win, Russian President Vladimir Putin will benefit above all, writes Jade McGlynn.
Information transfer in free space using ultraviolet, visible, or infrared waves has been gaining interest because of the availability of large bandwidth for high-data-rate communication. However, the presence of opaque occlusions or walls along the path between the transmitter and the receiver often impedes information transfer by blocking the direct line of sight.
In a new article published in Nature Communications, a team of researchers at UCLA Samueli School of Engineering and the California NanoSystems Institute, led by Dr. Aydogan Ozcan, the Chancellor’s Professor of Electrical & Computer Engineering, and Dr. Mona Jarrahi, the Northrop Grumman Endowed Chair at UCLA, has reported a fundamentally new method for delivering optical information around arbitrarily shaped opaque occlusions or walls.
This method permits the transmission of optical information, for example, images, around large and dynamically changing opaque occlusions. It is based on digital encoding at the transmitter and diffractive all-optical decoding at the receiver for transferring information around arbitrary opaque occlusions that completely block the direct line of sight between the transmitter and the receiver apertures.
