New framework applies machine learning to atomistic modeling: Method could lead to more accurate predictions of how new materials behave at the atomic scale
Northwestern University researchers have developed a new framework using machine learning that improves the accuracy of interatomic potentials — the guiding rules describing how atoms interact — in new materials design. The findings could lead to more accurate predictions of how new materials transfer heat, deform, and fail at the atomic scale. Designing new nanomaterials […]
More than 1.5 million children lost a primary or secondary caregiver due to the COVID-19 pandemic: Addressing the impact of caregiver deaths critical for pediatric mental health, authors note
More than 1.5 million children around the world are estimated to have lost at least one parent, custodial grandparent, or grandparent who lived with them due to death related to COVID-19 during the first 14 months of the pandemic, according to a study published today in The Lancet. The study highlights orphanhood as an urgent […]
Lower Linezolid Doses Effective Against Highly Resistant TB
Various doses of the potent antibacterial linezolid (Zyvox) appeared to have similar effectiveness in clearing pulmonary tuberculosis (TB) infection in patients who have developed multidrug resistance to the infection, researchers reported. In a four-arm study that compared linezolid doses of 600 and 1,200 mg given for either 2 or 6 months — along with standard […]
On-Demand PrEP Surpasses Daily Use Among Chinese MSM
Event-driven HIV prevention regimens appeared to have a better protective effect, and a better trend of medication adherence, than daily regimens in a real-world setting among men who have sex with men (MSM), a researcher said. In four cities in China, MSM who opted for event-driven pre-exposure prophylaxis (PrEP) — that is, that they only […]
Novel autoantibody adds fuel to COVID-19 ‘firestorm’ of inflammation, blood clots: The finding will likely help physicians develop targeted therapies for future COVID patients
Researchers at Michigan Medicine have discovered yet another functional autoantibody in COVID-19 patients that contributes to the disease’s development and the “firestorm” of blood clots and inflammation it induces. A growing body of studies suggests COVID-19 emulates many aspects of systemic autoimmune disorders, including the release of a flurry of overactive immune cells that produce […]
Private Equity Is Ruining American Healthcare
For-profit insurance companies have long been regarded as the ultimate offenders in medical profiteering. However, they distract from the unscrupulous involvement of private equity (PE) in medicine, a similarly culpable and even more insidious economic titan. PE is a unique, unregulated investment platform with the objective of aggressively generating short-term revenue for the firm and […]
Visibly transparent radiative cooler under direct sunlight
Since the Paris Climate Agreement that took effect in 2016, 121 countries have pledged to become carbon neutral by 2050 as the world tries to reduce its fuel consumption. The Korean government also unveiled its 2050 Carbon Neutral Strategy on December 7, 2020 and declared Carbon Zero, making transition to new and renewable energy a […]
Common medication used to reduce cholesterol levels may reduce COVID-19 severity
In a new study from University of California San Diego School of Medicine, researchers have confirmed that patients taking statin medications had a 41 percent lower risk of in-hospital death from COVID-19. The findings were published July 15, 2021 in PLOS ONE and expand upon prior research conducted at UC San Diego Health in 2020. […]
‘Neuroprosthesis’ restores words to man with paralysis: Technology could lead to more natural communication for people who have suffered speech loss
Researchers at UC San Francisco have successfully developed a “speech neuroprosthesis” that has enabled a man with severe paralysis to communicate in sentences, translating signals from his brain to the vocal tract directly into words that appear as text on a screen. The achievement, which was developed in collaboration with the first participant of a […]
Obamacare Marketplace Sign-ups Pass 2 Million, Likely Pushing Down Uninsured Rate
More than 2 million people have signed up for insurance through the Affordable Care Act’s online marketplaces since Feb. 15, taking advantage of the Biden administration’s extended period for open enrollment that began on that day, the Department of Health and Human Services announced on Wednesday. That figure means total marketplace enrollment is probably at an […]
