Phys.org / Seaweed farms boost long-term carbon storage by altering ocean chemistry, study shows
Seaweeds are versatile algae. They are sources of food, medicine, and many other products, and they have the added benefit of being extremely efficient at removing CO2 from the atmosphere as they grow.
Phys.org / Single-cell testing shows which antibiotics actually kill bacteria, not just stop growth
Drugs that act against bacteria are mainly assessed based on how well they inhibit bacterial growth under laboratory conditions. A critical factor, however, is whether the active substances actually kill the pathogens in ...
Phys.org / Smartphone use cuts into school hours, with social media leading the way
University of California, San Francisco investigators measured smartphone app activity during school hours among US adolescents and reported an average of 1.16 hours of use, with social media apps taking up the most time.
Tech Xplore / One image is all robots need to find their way
While the capabilities of robots have improved significantly over the past decades, they are not always able to reliably and safely move in unknown, dynamic and complex environments. To move in their surroundings, robots ...
Medical Xpress / 'Motivation brake' may explain why it's so hard to get started on an unpleasant task
Most of us know the feeling: maybe it is making a difficult phone call, starting a report you fear will be criticized, or preparing a presentation that's stressful just to think about. You understand what needs to be done, ...
Phys.org / Japanese study investigates how tariff policies influence long-run economic growth
Rising trade frictions over the past decade have sparked urgent questions about their long-term impact on global economies. The U.S. now applies tariffs of 66.4% on Chinese exports, which is higher compared to the average ...
Phys.org / Repeating fast radio burst shows diverse activity and hints at magnetar origin
Using the upgraded Giant Metrewave Radio Telescope (uGMRT), Indian astronomers have performed multi-frequency observations of a repeating fast radio burst designated FRB 20201124A. Results of these observations shed more ...
Medical Xpress / Common blood protein protects patients from lethal 'black fungus' infection, new study finds
Albumin is the most common protein in the blood, a vital molecule produced by the liver that helps maintain fluid balance and transports proteins and hormones. It also plays a key role in fighting off a lethal disease called ...
Phys.org / Ancient clay cylinders provide first foundation text documenting Nebuchadnezzar II's restoration of the ziggurat of Kish
In 2013, two local Iraqis handed over two inscribed clay cylinders to the State Board of Antiquities and Heritage. Subsequent analysis and translation of the inscriptions published in Iraq revealed them to belong to King ...
Phys.org / New chemical method makes it easier to select desirable traits in crops
Crops increasingly need to thrive in a broader range of conditions, including drought, salinity, and heat. Traditional plant breeding can select for desirable traits, but is limited by the genetic variation that already exists ...
Phys.org / Q&A: What do scientists need to learn next about blocking enzymes to treat disease?
Enzymes are the molecular machines that power life; they build and break down molecules, copy DNA, digest food, and drive virtually every chemical reaction in our cells. For decades, scientists have designed drugs to slow ...
Medical Xpress / Widely used pesticide linked to more than doubled Parkinson's risk
A new study from UCLA Health has found that long-term residential exposure to the pesticide chlorpyrifos is associated with more than a 2.5-fold increased risk of developing Parkinson's disease.
