Is that meat still good? Are you sure? McMaster researchers have developed a test to bring certainty to the delicate but critical question of whether meat and other foods are safe to eat or need to be thrown out.

Researchers from Case Western Reserve University School of Medicine and colleagues have discovered how two brain regions work together to maintain attention, and how discordance between the regions could lead to attention deficit disorders, including schizophrenia, bipolar disorder, and major depression.

Some materials are like people. Let them relax in the sun for a little while and they perform a lot better.

A collaboration led by Rice University and Los Alamos National Laboratory found that to be the case with a perovskite compound touted as an efficient material to collect sunlight and convert it into energy.

Arizona State University's School of Earth and Space Exploration recently released new research on its flagship Smart Course, Habitable Worlds, published in the peer-reviewed journal, Astrobiology. The study found that its student-centered, exploration-focused design resulted in high course grades and demonstrable mastery of content.

A team of Japanese researchers has discovered a new mechanism to explain stochastic resonance, in which sensitivity to weak signals is enhanced by noise. The finding is expected to help electronic devices become smaller and more energy-efficient.

Researchers from Aalto University in Finland and University of Cambridge in the United Kingdom have collected extensive data about the typing behavior of 168,000 volunteers. The researchers developed an online typing test following scientific standards and published it on the free typing speed assessment website typingmaster.com. Users transcribed sentences voluntarily after giving their informed consent that their anonymized data would be collected and used for research purposes.The test was taken by people from over 200 countries of whom 68% were from the US.

Animals may fall into what are called evolutionary and ecological traps when they make poor decisions using seemingly reliable environmental cues. For example, animals may select habitats to occupy based on food availability, but mortality may be highest in habitats with the highest food availability. A new Mammal Review article examines how the brown (grizzly) bear can fall into such traps in human-modified landscapes, which may contribute to decreases in brown bear populations.

How to treat patients who have microinvasive breast cancer - tumors that are 1 mm or less in size (the thickness of a dime) -- is somewhat controversial. Can these tiny tumors affect the lymph nodes and spread cancer to other areas of the body?

Physicians at the Virginia Piper Cancer Institute wanted to know if surgical procedures to test the lymph nodes for cancer were always necessary.

Manipulating the temperature and the length of time under which cocoa beans are roasted can simultaneously preserve and even boost the potency of some bioactive and antioxidant compounds while protecting desired sensory aspects of chocolate, according to Penn State researchers.

CORVALLIS, Ore. - The coastal marten, a small but fierce forest predator, is at a high risk for extinction in Oregon and northern California in the next 30 years due to threats from human activities, according to a new study.

Astronomers today announce one of the largest 3D maps of the infant Universe, in a presentation at the European Week of Astronomy and Space Science in Liverpool. A team led by Dr David Sobral of Lancaster University made the chart using the Subaru telescope in Hawaii and the Isaac Newton telescope in the Canary Islands. Looking back in time to 16 different epochs between 11 and 13 billion years ago, the researchers discovered almost 4000 early galaxies, many of which will have evolved into galaxies like our own Milky Way.

Developments in artificial intelligence may help us to predict the probability of life on other planets, according to new work by a team based at Plymouth University. The study uses artificial neural networks (ANNs) to classify planets into five types, estimating a probability of life in each case, which could be used in future interstellar exploration missions. The work is presented at the European Week of Astronomy and Space Science (EWASS) in Liverpool on 4 April by Mr Christopher Bishop.

Smokers have worse quality diets than former smokers or non-smokers, according to a study published in the open access journal BMC Public Health.

Dr Jacqueline Vernarelli at Fairfield University, Connecticut and Dr R. Ross MacLean at Yale University evaluated data from 5293 US adults and found that smokers consumed around 200 more calories a day, despite eating significantly smaller portions of food, than non-smokers or former smokers.

EVANSTON, Ill. --- Three-month-old babies cannot understand words and are just learning to roll over, yet they are already capable of learning abstract relations. In a new study, Northwestern University researchers show for the first time that 3-month-old infants can learn same and different relations.

Differences between signed and spoken languages are significant, yet the underlying neural processes we use to create complex expressions are quite similar for both, a team of researchers has found.
