Engineers 'sandwich' atomic layers to make new materials for energy storage

The scientists whose job it is to test the limits of what nature—specifically chemistry— will allow to exist, just set up shop on some new real estate on the Periodic Table. Using a method they invented for joining disparate elemental layers into a stable material with uniform, predictable properties, Drexel University researchers are testing an array of new combinations that may vastly expand the options available to create faster, smaller, more efficient energy storage, advanced electronics and wear-resistant materials.

New study shows correlation between microscopic structures and macroscopic properties

Researchers from Julich, Germany, have, together with colleagues from Austria, Italy, Colombia and the USA, developed a model system for so-called soft colloids. The model gives us a better understanding of correlations between the atomic structure of colloids and their perceptible material properties. These findings could lead to new approaches for the targeted development of innovative colloid materials. The results have just been published in the journal Nanoscale.

The decision to release the map was not made lightly.

Air pollution killing 4,000 in China a day, US study finds

Air pollution is killing about 4,000 people in China a day, accounting for 1 in 6 premature deaths in the world's most populous country, a new study finds.

Meat food waste has greater negative environmental impact than vegetable waste

Approximately 31 percent of food produced in the U.S., or 133 billion pounds of food worth $162 billion, was wasted in 2011 according to the United States Department of Agriculture (USDA). Now, University of Missouri researchers have found that the type of food wasted has a significant impact on the environment. Although less meat is wasted (on average) compared to fruits and vegetables, the researchers found that significantly more energy is used in the production of meat compared to the production of vegetables. This wasted energy is usually in the form of resources that can have negative impacts on the surrounding environment, such as diesel fuel or fertilizer being released into the environment.

Study shows how climate change threatens health

Researchers at Columbia University's National Center for Disaster Preparedness (NCDP) and the University of Washington have published a new study focused on the public health implications of climate change.

In an open letter I helped publish on July 28 – which has now been signed by more than 2,700 artificial intelligence (AI) and robotics researchers from around the world – we stated that "starting a military AI arms race is a bad idea, and should be prevented by a ban on offensive autonomous weapons beyond meaningful human control".

Don't expect straight answers on data sharing from the firms that profit from it

Data is a new currency of sorts: we all generate a lot of it, and many companies already use it to serve their ends or ours. But, for many very good reasons, it's not easy to persuade people that they should give their data away. There are more than enough surveillance scandals or data breaches to make an open approach seem like a bad idea.

How to protect planes and passengers from explosions on the surface of the sun

Air travel today is extraordinarily safe. Despite the high profile downings of MH370 and MH17, aviation magazine Flightglobal found 2014 to be the safest ever year of air travel.

Breaking the US government's hold on the internet won't be easy

The internet today is far bigger and more inextricably linked to our daily lives than its creators in the 1970s and 1980s could have imagined. So perhaps it is not surprising that some of the structures put in place decades ago may have failed to keep pace with its rapid evolution.

Researchers carefully protect dangerous pathogens – but how secure are all their data?

Ebola, smallpox, anthrax and many others: the most dangerous microorganisms are strictly regulated in the United States. The federal government oversees use of 65 so-called select agents with "the potential to pose a severe threat to public, animal or plant health, or to animal or plant products." Before scientists can work with them to learn more, find cures or create vaccines, they must meet a long list of conditions. The goal is to keep deadly infectious agents safely under lock and key, where they can't threaten the general population or fall into the wrong hands.

Unlikely element turns up in enzyme; commercial renewable fuels might ultimately result

Tungsten is exceptionally rare in biological systems. Thus, it came as a huge surprise to Michael Adams, PhD., and his collaborators when they discovered it in what appeared to be a novel enzyme in the hot spring-inhabiting bacterium, Caldicellulosiruptor bescii. The researchers hypothesized that this new tungstoenzyme plays a key role in C. bescii's primary metabolism, and its ability to convert plant biomass to simple fermentable sugars. This discovery could ultimately lead to commercially viable conversion of cellulosic (woody) biomass to fuels and chemical feedstocks, which could substantially reduce greenhouse emissions. The research is published 14 August in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.

Studies reveal how anesthesia's brain effects differ in older adults and in children

Recent Massachusetts General Hospital (MGH) investigations into the neurobiology underlying the effects of general anesthesia have begun to reveal the ways different anesthetic agents alter specific aspects of the brain's electrical signals, reflected by EEG (electroencephalogram) signatures. While those studies have provided information that may lead to improved techniques for monitoring the consciousness of patients receiving general anesthesia, until now they have been conducted in relatively young adult patients. Now a series of papers from MGH researchers is detailing the differences in the way common anesthetics affect the brains of older patients and children, findings that could lead to ways of improving monitoring technology and the safety of general anesthesia for such patients.
