Mistaken belief in mythical causes of cancer is rife according to new research.

Napping can help tired teens' performance in school

Wednesday April 25th, 2018 11:56:21 PM
Researchers have found a positive relationship between midday-napping and nighttime sleep. They believe it might be key to boosting neurocognitive function in early adolescents. The team examined adolescents in Jintan, China, measuring midday napping, nighttime sleep duration and sleep quality, and performance on multiple neurocognitive tasks. Habitual nappers (who napped more often) tended to have a better nighttime sleep.

A Yellowstone guide to life on Mars

Wednesday April 25th, 2018 11:56:18 PM
A geology student is helping NASA determine whether life existed on other planets. He is helping find a marker for ancient bacterial life on Mars. The research could help scientists put to rest one of our most fundamental mysteries.

Many low-lying atoll islands could be uninhabitable by mid-21st century

Wednesday April 25th, 2018 08:20:44 PM
Sea-level rise and wave-driven flooding will negatively impact freshwater resources on many low-lying atoll islands in such a way that many could be uninhabitable in just a few decades.

Projectile cannon experiments show how asteroids can deliver water

Wednesday April 25th, 2018 08:20:42 PM
New research shows that a surprising amount of water survives simulated asteroid impacts, a finding that may help explain how asteroids deposit water throughout the solar system.

Ultrahigh-pressure laser experiments shed light on super-Earth cores

Wednesday April 25th, 2018 08:20:39 PM
Using high-powered laser beams, researchers have simulated conditions inside a planet three times as large as Earth. The pressures achieved in this study, up to 1,314 gigapascals (GPa), allowed researchers to gather the highest-pressure X-ray diffraction data ever recorded and generate new, more robust models for the interior structure of large, rocky exoplanets.

New link between sleep arousals and body temperature may also be connected to SIDS

Wednesday April 25th, 2018 08:20:37 PM
What is the origin of these arousals? Scientists have discovered that brief arousals are probably triggered by the intrinsic electrical noise from wake-promoting neurons (WPN) in the brain. Their research reveals a previously unrecognized neurophysiological mechanism that links sleep arousals with temperature regulation, and may also provide an important new link between temperature and Sudden Infant Death Syndrome (SIDS).

World's smallest optical implantable biodevice

Wednesday April 25th, 2018 08:20:34 PM
Researchers have built a new optical device no bigger than the edge of a coin. The device includes a photovoltaic cell that is powered by infrared light and emits blue light. Using infrared light allows the device to be implanted several centimeters deep into the body, while the emission of blue light can be used for optogenetic control of brain patterns.

Weather associated with sentiments expressed on social media

Sentiments expressed on Facebook and Twitter may be associated with certain weather patterns.

Massive study across western equatorial Africa finds more gorillas and chimpanzees than expected

Wednesday April 25th, 2018 08:20:28 PM
A massive decade-long study of Western Equatorial Africa's gorillas and chimpanzees has uncovered both good news and bad about our nearest relatives. The good news: there are one third more western lowland gorillas and one tenth more central chimpanzees than previously thought. The bad news: the vast majority of these great apes (80 percent) exist outside of protected areas, and gorilla populations are declining by 2.7 percent annually.

New approach to treating patients with stage IV Wilms tumor

Wednesday April 25th, 2018 08:20:26 PM
A new study shows significantly improved survival rates for patients with stage IV Wilms tumors with lung metastases.

Brain structure linked to symptoms of restless legs syndrome

Wednesday April 25th, 2018 08:20:23 PM
People with restless legs syndrome may have changes in a portion of the brain that processes sensory information, according to a new study.

Balancing nuclear and renewable energy

Wednesday April 25th, 2018 08:20:20 PM
Researchers explore the benefits of adjusting the output of nuclear power plants according to the changing supply of renewable energy such as wind and solar power.

Russian Arctic glacier loss doubles as temps warm

Wednesday April 25th, 2018 08:20:15 PM
Ice mass loss in the Russian Arctic has nearly doubled over the last decade.

When do problems with memory and decision-making affect older adults' ability to drive?

Wednesday April 25th, 2018 08:20:13 PM
Recently, a team of researchers designed a study to learn more about cognitive health and older drivers' crash risks. The study focused on links between levels of cognitive function and crash risk among older drivers without dementia over a 14-year study period. They also assessed the link between changes in cognitive function over time and later risks of crashes.

Drug-filled, 3-D printed dentures could fight off infections

Wednesday April 25th, 2018 08:20:10 PM
Researchers have developed 3-D printed dentures filled with antifungal medication to better treat oral fungal infections.

Emerging memory devices used to develop electronic circuits for cybersecurity applications

Wednesday April 25th, 2018 08:20:07 PM
While we embrace the way the Internet of Things already is making our lives more streamlined and convenient, the cybersecurity risk posed by millions of wirelessly connected gadgets, devices and appliances remains a huge concern. Even single, targeted attacks can result in major damage; when cybercriminals control and manipulate several nodes in a network, the potential for destruction increases.

Engineers get a grip on slippery surfactants

Wednesday April 25th, 2018 08:20:02 PM
A group's innovative surfactant theory removes limitations of a 100-year-old model for interfacial behavior in enhanced oil recovery.

3-D print electronics and cells printed directly on skin

Wednesday April 25th, 2018 05:19:14 PM
In a groundbreaking new study, researchers used a customized, low-cost 3-D printer to print electronics on a real hand for the first time. The technology could be used by soldiers on the battlefield to print temporary sensors on their bodies to detect chemical or biological agents or solar cells to charge essential electronics.
