A 60-year-old mystery about the source of energetic, potentially damaging particles in Earth's radiation belts has been solved using data from a shoebox-sized satellite built and operated by students. The satellite is called a CubeSat.

Imagine a fully instrumented satellite the size of a half-gallon milk carton. Then imagine that milk carton whirling in space, catching never-before-seen glimpses of atmospheric and geospace processes.

Digital screen use is a staple of contemporary life for adults and children, whether they are browsing on laptops and smartphones, or watching TV. Paediatricians and scientists have long expressed concerns about the impact of overusing technology on people's wellbeing. However, new Oxford University research suggests that existing guidance managing children's digital media time may not be as beneficial as first thought.

Adolescents who are willing to exploit others for personal gain are more likely to bully and have sex than those who score higher on a measure of honesty and humility. This is according to a study in Springer's journal Evolutionary Psychological Science which was led by Daniel Provenzano of the University of Windsor in Canada.

Our Georgian and Victorian ancestors probably celebrated Christmas with more modest wine consumption than we do today - if the size of their wine glasses are anything to go by. Researchers at the University of Cambridge have found that the capacity of wine glasses has increased seven-fold over the past 300 years, and most steeply in the last two decades as wine consumption rose.

Plesiosaurs were especially effective swimmer. These long extinct "paddle saurians" propelled themselves through the World's oceans by employing "underwater flight" - similar to sea turtles and penguins. Paleontologist from the University of Bonn, Germany, now describe the oldest plesiosaur in the journal Science Advances, together with colleagues from Japan and France. The find comes from the youngest part of the Triassic period and is about 201 million years old.

Many people don't worry about the security of their personal information until it's too late. And protecting data is even more important for military personnel, whose lives could be in danger if some types of information were to get into the wrong hands. Now, one group reports in ACS Nano a new way to protect data, especially when it is subjected to extreme environmental conditions.

PISCATAWAY, NJ - State alcohol excise taxes are typically only a few cents per drink and have not kept pace with inflation, according to a new study in the January issue of the Journal of Studies on Alcohol and Drugs. Raising those taxes, according to the authors, represents an opportunity for states to increase revenues while simultaneously improving public health outcomes and costs related to excessive alcohol consumption.

PITTSBURGH, Dec. 13, 2017 - Playing an adventure video game featuring a fictitious, young emergency physician treating severe trauma patients was better than text-based learning at priming real doctors to quickly recognize the patients who needed higher levels of care, according to a new trial led by the University of Pittsburgh School of Medicine.

LAWRENCE -- People's racial and political identities strongly shaped how they viewed the causes of several recent widely publicized police encounters that resulted in the deaths of African American men, according to a new study by two University of Kansas researchers.

Men are more likely to go missing on a night out and be found dead in December than at any other time of the year, according to a sobering new report from the University of Portsmouth.

Christmas revellers are being urged to look out for each other as researchers identify the winter months from December to February as a high risk period for party-going males.

Taking a route home near water poses a particular danger, with 89 per cent of missing fatalities being discovered later in canals, rivers, lakes or harbours.
