Melting glaciers may speed carbon emissions, fuel climate feedback loop

Melting glaciers may speed carbon emissions, fuel climate feedback loop

Science
March 15 (UPI) -- While some of the consequences of climate change have a balancing effect, working to slow warming patterns, many more seem to fuel feedback loops that accelerate warming. Now, an international team of scientists led by researchers at the University of Leeds has found another. According to their analysis, the loss of alpine glaciers has made mountain rivers friendlier to fungi, accelerating plant decomposition and carbon emissions. Advertisement Researchers described the feedback loop in a new paper, published Monday in the journal Nature Climate Change. With alpine glaciers the smallest they've been in thousands of years, mountain rivers are getting warmer. They've also become less prone to water flow variability and sediment movement, allowing fungi to flourish. When f...
Chiefs, Bucs simulate speed and gam tempo for Super Bowl LV

Chiefs, Bucs simulate speed and gam tempo for Super Bowl LV

Sports
MIAMI, Feb. 6 (UPI) -- The Kansas City Chiefs and Tampa Bay Buccaneers simulated the speed of each other's respective playmakers, prepared for changes in game tempo and altered their play-calling techniques this week for Sunday's Super Bowl LV. Tampa Bay and Kansas City remained at their home facilities throughout the week as a safety precaution for COVID-19. The Buccaneers will play in their home stadium for the Super Bowl. The Chiefs are to arrive in Tampa, Fla., on Saturday. Advertisement Despite the major changes in the format for a typical Super Bowl week, the teams have used the time to progressively ramp up their energy so they are at peak performance levels when the game kicks off at 6:30 p.m. EST at Raymond James Stadium. The Buccaneers and Chiefs must not only be in great physic...
US asking states to speed vaccine, not hold back 2nd dose

US asking states to speed vaccine, not hold back 2nd dose

Health
WASHINGTON -- Barely a month into a mass vaccination campaign to stop the COVID-19 pandemic, the Trump administration unexpectedly shifted gears Tuesday to speed the delivery of shots. The move came after widespread concern over a slow start even as coronavirus cases and deaths reach alarming new highs.Health and Human Services Secretary Alex Azar announced a series of major changes to increase supply of vaccines and expand the age groups eligible as well as locations where people can get shots.One change will have some teeth to it. Azar said going forward the federal government will base each state's allocation of vaccines partly on how successful states have been in administering those already provided.“If you are not using vaccines that you have the right to, then we should be rebalanci...
Quantum insulators could improve speed, efficiency of digital information transfer

Quantum insulators could improve speed, efficiency of digital information transfer

Science
Dec. 16 (UPI) -- The phenomenon known as the quantum anomalous Hall effect describes the ability of electrons to move freely along at the outer edges of materials. Electrons propelled by the QAH effect can travel at high speeds without losing energy. For the first time, researchers have generated the QAH effect in a multilayered insulator, creating a kind of multilane highway, across which electrons can travel. Advertisement The breakthrough, described Wednesday in the journal Nature, could be used to build more energy efficient electronic devices. "Increasing the number of electrons in most metals results in a sort of traffic jam because electrons moving in different directions get scattered and repel each other," lead researcher Cui-Zu Chang said in a news release. "But in QAH insulato...

The Latest: Speed of viral spread causes concern in S. Korea

Health
SEOUL, South Korea — South Korea has reported more than 500 new coronavirus cases for the third straight day, the speed of viral spread unseen since the worst wave of the outbreak in spring.The 504 cases reported by the Korea Disease Control and Prevention on Saturday brought the national caseload to 33,375, including 522 deaths.Around 330 of the new cases came from the densely populated Seoul metropolitan area, home to about half of the country’s 51 million population, where health workers are struggling to stem transmissions linked to hospitals, schools, saunas, gyms and army units.Infections were also reported in other major cities including Daegu, which was the epicenter of the country’s previous major outbreak in late February and March.The recent spike in infections came after the go...
