Kicking neural network automation into high gear Posted: 21 Mar 2019 12:28 PM PDT Algorithm designs optimized machine-learning models up to 200 times faster than traditional methods. |
High-fructose corn syrup boosts intestinal tumor growth in mice Posted: 21 Mar 2019 11:19 AM PDT Consuming a daily modest amount of high-fructose corn syrup -- the equivalent of people drinking about 12 ounces of a sugar-sweetened beverage daily -- accelerates the growth of intestinal tumors in mouse models of the disease, independently of obesity, according to new research. |
Dynamic hydrogel used to make 'soft robot' components and LEGO-like building blocks Posted: 21 Mar 2019 11:19 AM PDT A new type of hydrogel material could soon make assembling complex microfluidic or soft robotic devices as simple as putting together a LEGO set. |
Inert nitrogen forced to react with itself Posted: 21 Mar 2019 11:19 AM PDT Direct coupling of two molecules of nitrogen: chemists have achieved what was thought to be impossible. This new reaction opens new possibilities for one of the most inert molecules on earth. |
Engineers demonstrate metamaterials that can solve equations Posted: 21 Mar 2019 11:19 AM PDT Engineers have designed a metamaterial device that can solve integral equations. The device works by encoding parameters into the properties of an incoming electromagnetic wave; once inside, the device's unique structure manipulates the wave in such a way that it exits encoded with the solution to a pre-set integral equation for that arbitrary input. |
How team sports change a child's brain Posted: 21 Mar 2019 10:51 AM PDT Adult depression has long been associated with shrinkage of the hippocampus, a brain region that plays an important role in memory and response to stress. Now, new research has linked participation in team sports to larger hippocampal volumes in children and less depression in boys ages 9 to 11. |
Hundreds of bubble streams link biology, seismology off Washington's coast Posted: 21 Mar 2019 10:09 AM PDT The first survey of methane vent sites off Washington's coast finds 1,778 bubble columns, with most located along a north-south band that is in line with a geologic fault. |
In a new quantum simulator, light behaves like a magnet Posted: 21 Mar 2019 10:03 AM PDT Physicists propose a new 'quantum simulator': a laser-based device that can be used to study a wide range of quantum systems. Studying it, the researchers have found that photons can behave like magnetic dipoles at temperatures close to absolute zero, following the laws of quantum mechanics. The simple simulator can be used to better understand the properties of complex materials under such extreme conditions. |
Physicists reveal why matter dominates our universe Posted: 21 Mar 2019 10:03 AM PDT Physicists have confirmed that matter and antimatter decay differently for elementary particles containing charmed quarks. |
World's smallest bears' facial expressions throw doubt on human superiority Posted: 21 Mar 2019 07:28 AM PDT The world's smallest bears can exactly mimic another bear's facial expressions, casting doubt on humans and other primates' supremacy at this subtle form of communication. It is the first time such exact facial mimicry has been seen outside of humans and gorillas. |
True-meaning wearable displays: Self-powered, washable and wearable Posted: 21 Mar 2019 07:28 AM PDT When we think about clothes, they are usually formed with textiles and have to be both wearable and washable for daily use; however, smart clothing has had a problem with its power sources and moisture permeability, which causes the devices to malfunction. This problem has now been overcome by a research team, who developed a textile-based wearable display module technology that is washable and does not require an external power source. |
Ancient birds out of the egg running Posted: 21 Mar 2019 07:28 AM PDT Using their own laser imaging technology, scientists have determined the lifestyle of a special hatchling bird by revealing the previously unknown feathering preserved in the fossil specimen found in the ~125 million-year-old Early Cretaceous fossil beds of Los Hoyas, Spain. |
Medicine and personal care products may lead to new pollutants in waterways Posted: 21 Mar 2019 06:22 AM PDT When you flush the toilet, you probably don't think about the traces of the medicine and personal care products in your body that are winding up in sewage treatment plants, streams, rivers, lakes, bays and the ocean. But scientists have found that bacteria in sewage treatment plants may be creating new contaminants that have not been evaluated for potential risks and may affect aquatic environments. |
Evidence for a Human Geomagnetic Sense Posted: 21 Mar 2019 05:36 AM PDT Scientists develop a robust experiment that shows human brain waves respond to changes in Earth-strength magnetic fields. |
