A group of University of California, San Diego researchers set out to gain a better understanding of the thermal balance of power plants and surfaces, like heliostat mirrors or solar panels, when exposed to both solar (shortwave) and atmospheric (longwave) radiation. They quickly realized that they would first need to determine what roles cloud cover and relative humidity play in the transparency of the atmosphere to radiation at temperatures common on Earth.

These neurons affect how much you do, or don't, want to eat
Like a symphony, multiple brain regions work in concert to regulate the need to eat. University of Arizona researchers believe they have identified a symphony conductor—a brain region that regulates appetite suppression and activation—tucked within the amygdala, the brain's emotional hub.

Researchers study healthy ALS neurons as way to understand resistance to the disease
Although largely paralyzed, ALS patients can communicate through eye-tracking devices because they retain eye movement until the disease's late stages. Yet, how some motor neurons resist ALS to allow for this movement has been a mystery.

Symbiotic upcycling: Turning 'low value' compounds into biomass
Plants use light energy from the sun for photosynthesis to turn carbon dioxide (CO2) into biomass. Animals can't do that. Therefore, some of them have teamed up with bacteria that carry out a process called chemosynthesis. It works almost like photosynthesis, only that it uses chemical energy instead of light energy. Many animals rely on chemosynthetic bacteria to supply them with food. The symbionts turn CO2 into biomass and are subsequently digested by their host. Kentron, a bacterium nourishing the ciliate Kentrophoros, was thought to be 'just another' chemosynthetic symbiont. However, recent results indicate that it is not.

Mice with a human immune system help research into cancer and infections
Researchers from Aarhus University and Aarhus University Hospital have succeeded in using mice with a transplanted human immune system to study functions in the immune system which are otherwise particularly difficult to study. The method could turn out to be important in further research into cancer, HIV and autoimmune diseases.

Atmospheric rivers getting warmer along U.S. West Coast
Most of the West Coast of the United States relies on a healthy winter snowpack to provide water through the dry summer months. But when precipitation falls as rain rather than snow, it can diminish summer water supplies, as well as trigger floods and landslides.

New therapy promotes vascular repair following stroke
Following a stroke, antibodies that inhibit the signaling molecule Nogo-A can help repair blood vessels in the affected brain regions. This also promotes the regaining of motor functions, researchers at the University of Zurich have shown in a mouse model. The study opens up new avenues for treatment.

PizzaGAN gets the picture on how to make a pizza
Is nothing sacred? Who would dare to even attempt to talk about a machine-learning experiment that results in the perfect (gasp) pizza? It is difficult to contemplate, but a research quintet did not shy away from trying, and they worked to teach a machine how to make a great pie.
