A research group from the Medical University of Vienna reports how the hormone leptin stimulates the liver to export lipids and reduce the fat production in the liver. This occurs due to the activation of neurons in the brain stem. These findings provide new approaches for the fight against non-alcoholic fatty liver disease, which often occurs in connection with obesity. The results were just published in Nature Communications.

Newly discovered immune cells at the frontline of HIV infection
Researchers at The Westmead Institute for Medical Research have discovered brand new immune cells that are at the frontline of HIV infection. Known as CD11c+ dendritic cells, these new cells are more susceptible to HIV infection and can then transmit the virus to other cells.

Advanced computational modeling of the gut for biodefense
The Nutritional Immunology and Molecular Medicine Laboratory (NIMML) has developed a high-resolution model of the gut immune system by using advanced computational systems. The new high-performance computing (HPC)-driven model of the gut predicts new emerging behaviors and responses to biological threats. The gut ecosystem includes trillions of interactions between host epithelial and immune cells, molecules (cytokines, chemokines and metabolites) and microbes is a massively and dynamically interacting network, similar to a multidimensional jigsaw puzzle with pieces that are constantly changing shape. These interactions with cooperativity and feedback lead to nonlinear dynamics and unforeseen emergent behaviors across spatiotemporal scales. The NIMML model of the gut facilitates discovering new knowledge within this complex system for biodefense applications.

Scientists map huge undersea fresh-water aquifer off US Northeast
In a new survey of the sub-seafloor off the U.S. Northeast coast, scientists have made a surprising discovery: a gigantic aquifer of relatively fresh water trapped in porous sediments lying below the salty ocean. It appears to be the largest such formation yet found in the world. The aquifer stretches from the shore at least from Massachusetts to New Jersey, extending more or less continuously out about 50 miles to the edge of the continental shelf. If found on the surface, it would create a lake covering some 15,000 square miles. The study suggests that such aquifers probably lie off many other coasts worldwide, and could provide desperately needed water for arid areas that are now in danger of running out.

Perovskite solar cells tested for real-world performance—in the lab
It was only ten years ago that metal-halide perovskites were discovered to be photovoltaic materials. Today, perovskite solar cells are almost as efficient as the best conventional silicon ones, and there is much hope that they will become a highly efficient and low-cost alternative, as they can be manufactured by rather simple and fast methods like printing.

Neural networks taught to recognize similar objects on videos without accuracy degradation
Andrey Savchenko, Professor at the Higher School of Economics (HSE University), has developed a method that can help to enhance image identification on videos. In his project, a network was taught by a new algorithm and can now make decisions on image recognition and classification at a rate 10 times faster than before. This research was presented in the paper "Sequential three-way decisions in multi-category image recognition with deep features based on distance factor" published in Information Sciences.

Researching slang to help solve gang crime
Gang-related violent crime continues to affect young people across England and Wales, with the latest reports suggesting that gang leaders are offering teenagers up to £1,000 pounds to carry out stabbings. In their efforts to curb violence among young people, police and politicians must distinguish between those who are involved in crime and those who are innocent—or risk further marginalizing deprived communities.

NASA helps warn of harmful algal blooms in lakes, reservoirs
Harmful algal blooms can cause big problems in coastal areas and lakes across the United States. When toxin-containing aquatic organisms multiply and form a bloom, it can sicken people and pets, contaminate drinking water, and force closures at boating and swimming sites.

Algorithm quickly finds hidden objects in dense point clouds
A new MIT-developed technique enables robots to quickly identify objects hidden in a three-dimensional cloud of data, reminiscent of how some people can make sense of a densely patterned "Magic Eye" image if they observe it in just the right way.
