A new study finds that taking pictures of PowerPoint slides during an online presentation helped students remember the slide content better than for slides they did not photograph.

A study found that 57 percent of the participants were habitual snoozers.

New research finds that flooding can affect food security for over 5.6 million people across several African nations. The work comes at a time when floods have also devastated Pakistan, India, and large parts of the European Union and the United States.

A new study uses carbon isotope science to show that marked tusks in a seized ivory shipment were more than 30 years old and likely had found their way from a guarded government stockpile into the hands of illegal ivory traders. The results suggest that governments that maintain ivory stockpiles may want to take a closer look at their inventory.

Targeting a specific enzyme in the muscle could help cancer patients preserve muscle mass and potentially prolong their survival, according to new research.

For the first time, zinc isotope ratios in tooth enamel have been analysed with the aim of identifying the diet of a Neanderthal. The Neanderthal to whom the tooth belonged was probably a carnivore. Other chemical tracers indicate that this individual did not consume the blood of their prey, but ate the bone marrow without consuming the bones.

In an analysis of the metabolic profiles of healthy American babies, researchers found surprising differences among ethnic groups which may help make screening for inherited metabolic disorders, cystic fibrosis, or hypothyroidism much more accurate than traditional genetic disease screens.

An analysis of obsidian artifacts excavated during the 1960s at two prominent archaeological sites in southwestern Iran suggests that the networks Neolithic people formed in the region as they developed agriculture are larger and more complex than previously believed. The study has applied state-of-the-art analytical tools to a collection of 2,100 obsidian artifacts.

Terrestrial agriculture provides the backbone of the world's food production system. A new article makes the case for increased investment in algae aquaculture systems as a means of meeting nutritional needs while reducing the ecological footprint of food production.

Genetic and genomic technologies have tremendous potential for protecting marine life, but are currently being underutilized, according to a new article.

By the end of this century, permafrost in the rapidly warming Arctic will likely emit as much carbon dioxide and methane into the atmosphere as a large industrial nation, and potentially more than the U.S. has emitted since the start of the industrial revolution. A new study forecasts cumulative emissions from this 'country of permafrost' through 2100 under low, medium, and high warming scenarios....

A major new project will help benchmark biodiversity change in the Arctic Ocean and guide conservation efforts by identifying unique species and assessing their extinction risk.

Researchers are learning more about the effects of herbicide exposure during pregnancy.

Eating fire ants might prepare a lizard's immune system to be stung by the ants, according to a new study.

Among patients with kidney cancer, the activity of four specific genes in the cancer cells seems to be able to predict the risk of the tumor spreading and the patient's chances of survival.

Researchers have uncovered a previously unknown property of colloidal crystals, highly ordered three-dimensional arrays of nanoparticles.

People with a disease characterized by lung scarring that has no obvious cause are more likely to die if they live in areas with higher levels of air pollution composed of chemicals associated with industrial sources and vehicular traffic, according to new research.

A research team has created an artificial intelligence model that could significantly improve the accuracy and reduce the time and cost of the drug development process. The new model, called CODE-AE, can screen novel drug compounds to accurately predict efficacy in humans.

Omnipose, a deep learning software, is helping to solve the challenge of identifying varied miniscule bacteria in microscopy images. It can also identify several other types of tiny objects in micrographs. It was not easily fooled by extreme changes in a cell's shape due to antibiotic treatment or antagonism by chemicals produced during interbacterial aggression. In fact, it could even detect...

Researchers have discovered a molecule in the brain responsible for orchestrating the immune system's responses to Alzheimer's disease and multiple sclerosis (MS), potentially allowing doctors to supercharge the body's ability to fight those and other devastating neurological diseases.

Alien floras in regions that were once occupied by the same European power are, on average, more similar to each other compared to outside regions and this similarity increases with the length of time a region was occupied.

While the standard treatment for HIV can hold the disease in check, a new study shows how experimental medicines can boost the body's own ability to suppress the virus. An important step towards a cure, say researchers behind the study.

Pregnant smokers reduced their smoking by an average of one cigarette per day before becoming aware they were pregnant, reports a new study of more than 400 pregnant people. Then, in the month after learning of their pregnancy, participants reduced smoking by another four cigarettes per day.

Engineers have introduced a holistic system that integrates sensing, storage and processing at the sensor's edge to enable efficient and secure signal processing. Brain-inspired hardware minimizes power consumption for numerous applications requiring interpretation of visual images and ultrasound, chemical detection and bio-sensing, time-of-flight data for topological mapping and kinetics.
