In the latest experiment of its kind, researchers have captured the most compelling evidence to date that unusual particles lurk inside a special kind of superconductor. The result, which confirms theoretical predictions first made nearly a decade ago at the Joint Quantum Institute (JQI) and the University of Maryland (UMD), will be published in the April 5 issue of Nature.
Infrared imagery from NASA's Aqua satellite revealed that Tropical Storm Jelawat was getting stronger as it moved through the Northwestern Pacific Ocean.
NASA's Aqua satellite passed over Jelawat on March 28 at 12:11 a.m. EDT (0411 UTC) and analyzed the storm in infrared light. Infrared light provides temperature data and that's important when trying to understand how strong storms can be. The higher the cloud tops, the colder and the stronger they are.
Ragweed, its pollen potent to allergy sufferers, might be more than a source of sneezes. In the Midwest, the plant may pose a threat to soybean production.
Scientists have found that ragweed can drastically reduce soybean yield.
"It wasn't really a weed we were worried about too much," says Ethann Barnes, a graduate research assistant in agronomy and horticulture at the University of Nebraska-Lincoln. "We didn't expect it to be this competitive."
Mandatory nutrition policies could be a valuable tool in helping high school students to lower their sugar intake, a University of Waterloo study has found.
The study compared the consumption of sugar-sweetened drinks between 41,000 secondary school students in Ontario, where school nutrition policies are mandatory, and Alberta, where they are voluntary. The study took place during the 2013-14 school year.
Philadelphia, March 27, 2018 - About one third of cancer cases are estimated to be linked to dietary and other modifiable risk factors, especially for obesity-related cancers such as breast, colorectal, ovarian, endometrial, kidney, gallbladder, esophageal, and pancreatic cancers.
BOSTON, MASS. - You're waiting to get your teeth cleaned, half-dozing in a chair with your mouth propped open when a robot appears to do the job. Would you be willing to undergo a dental cleaning performed by a robot? How about a root canal? Autonomous gum surgery, anyone?
What if the robotic procedure was offered at half-price?
Satellite imagery showed that Tropical Depression Jelawat was still dealing with southerly vertical wind shear that was pushing the bulk of its clouds north of its center.
On March 27, Jelawat was centered over 100 miles from Yap State in the Northwestern Pacific Ocean. Yap State is one of four states in the Federated States of Micronesia. The other states are Chuuk State, Kosrae State and Pohnpei State.
Tropical Cyclone Iris is being battered by wind shear so strong that it doesn't even look like a circular storm.
The Joint Typhoon Warning Center issued their final warning on Tropical Cyclone Iris as wind shear continued tearing the storm apart. Iris' exposed low-level center was even difficult to find on infrared imagery from NASA as wind shear stretched the storm out.
Anyone who has sat down to a summer crab feast knows how hard, messy and delicious they are.
But University of Cincinnati biologist Bruce Jayne found some water snakes that specialize in catching and consuming live crabs, without the benefit of mallets, bibs or utensils.
Snakes can't chew their food so anything they eat must be bite-sized, even if this amuse-bouche sometimes is an antelope. A species of water snake in Malaysia defies this limitation by ripping crabs into manageable bite-sized pieces, Jayne found.
A defining characteristic of stroke is the loss of motor control due to structural damage in specific brain areas. In fact, motor impairments (or deficits) are the number one complication after stroke. Losing the ability to carry out basic bodily functions, such as speaking, walking and swallowing, can be devastating for stroke survivors. Unfortunately, there are few effective recovery options beyond physical and occupational therapy to stimulate brain re-learning.
PULLMAN, Wash. - Computer users -- at home and at work -- often engage in behaviors that create security risks and privacy threats, despite having a variety of security options available.
Clicking on unfamiliar links, choosing weak passwords and sharing personal information can leave a user's computer or employer open to having information stolen.
An analysis of data from a previous study of more than 1,350 smokers intending to quit after a hospitalization found that those who reported using electronic cigarettes (e-cigarettes) during the study period were less likely to have successfully quit smoking 6 months after entering the study. The authors caution, however, that because of the study's design, it cannot support the conclusion that e-cigarettes are not useful smoking cessation aids and stress the need for further investigation of that question.
Controlling greenhouse gas emissions in the coming decades could substantially reduce the consequences of carbon releases from thawing permafrost during the next 300 years, according to a new paper published this week in the Proceedings of National Academy of Sciences.
Conversely, climate policy that results in little or no effort to control greenhouse gases like carbon dioxide would likely result in a substantial release of carbon from the permafrost region by 2300, the study found.
A new approach to analyzing prostate gland tissue may help address a major challenge in treating prostate cancer - determining which tumors are unlikely to progress and which could be life threatening and require treatment.
DULUTH, Minnesota--A paper published this week in the journal Limnology and Oceanography Letters is the first to show that lake size and nutrients drive how much greenhouse gases are emitted globally from lakes into the atmosphere.
