New data processing module makes deep neural networks smarter

Artificial intelligence researchers have improved the performance of deep neural networks by combining feature normalization and feature attention modules into a single module that they call attentive normalization. The hybrid module improves the accuracy of the system significantly, while using negligible extra computational power.

New photoactivation mechanism for polymer production

A team of researchers has demonstrated a way to use low-energy, visible light to produce polymer gel objects from pure monomer solutions. The work not only poses a potential solution to current challenges in producing these materials, it also sheds further light on the ways in which low energy photons can combine to produce high energy excited states.

Reforestation can only partially restore tropical soils

Tropical forest soils play a crucial role in providing vital ecosystem functions. They provide nutrients for plants, store carbon and regulate greenhouse gases, as well as storing and filtering water, and protection against erosion. Scientists have investigated how the properties and ecosystem functions of tropical soils change when forests are cut down, and whether reforestation can reverse such...

A ferry protein in the pancreas protects it from the stress induced by a high-fat diet

Scientists have now uncovered a key mechanism by which pancreatic function is maintained in response to a high-fat diet. A protein present in pancreatic insulin-producing cells protects them from damage under the stress induced by a high-fat diet. As the world increases its intake of high-fat foods and as type 2 diabetes incidence rises as a result, this protein could be a novel therapeutic target...

A new species of spider

During a research stay in the highlands of Colombia conducted as part of her doctorate, a PhD student has discovered and zoologically described a new species of spider.

Physicists develop basic principles for mini-labs on chips

Colloidal particles have become increasingly important for research as vehicles of biochemical agents. In future, it will be possible to study their behavior much more efficiently than before by placing them on a magnetized chip. A research team has discovered that colloidal rods can be moved on a chip quickly, precisely, and in different directions. A pre-programmed magnetic field even enables...

Security software for autonomous vehicles

Before autonomous vehicles participate in road traffic, they must demonstrate conclusively that they do not pose a danger to others. New software prevents accidents by predicting different variants of a traffic situation every millisecond.

Marine animals live where ocean is most breathable, ranges may shrink with climate change

New research shows that a wide variety of marine animals -- from vertebrates to crustaceans to mollusks -- already inhabit the maximum range of breathable ocean that their physiology will allow. The findings provide a warning about climate change: Since warmer waters will harbor less oxygen, some stretches of ocean that are breathable today for a given species may not be in the future.
