Parasites take an enormous toll on human and veterinary health. But researchers may have found a way for patients with brain disorders and a common brain parasite to become frenemies.A new study published in Nature Microbiology has pioneered the use of a single-celled parasite, Toxoplasma gondii, to inject therapeutic proteins into brain cells. The brain is very picky about what it lets in, including many drugs, which limits treatment options for neurological conditions.As a professor of microbi ...read more
My colleagues and I have developed an artificial intelligence system that helps buildings shift their energy use to times when the electric grid is cleaner.I’m an engineer who studies and develops smart buildings. My lab created Merlin, which learns how people use energy in their homes and adjust energy controls like thermostats to meet their needs while at the same time minimizing the impact on the grid. The system can learn on one set of buildings and occupants and be used in buildings with ...read more
As we focused our microscope on the soil sample for the first time, bits of organic material came into view: a tiny poppy seed, the compound eye of an insect, broken willow twigs and spikemoss spores. Dark-colored spheres produced by soil fungi dominated our view.These were unmistakably the remains of an arctic tundra ecosystem– and proof that Greenland’s entire ice sheet disappeared more recently than people realize.These tiny hints of past life came from a most unlikely place – a handful ...read more
In space, there are clouds that contain gas and dust ejected from stars. Our solar system was formed 4.6 billion years ago from such a molecular cloud. Most of these dust grains were destroyed during solar system formation. The dark areas in this image of the Carina Nebula are molecular clouds. NASA, ESA, N. Smith (U. California, Berkeley) et al., and The Hubble Heritage Team (STScI/AURA)However, a very small amount of the grains survived and remained intact in primitive meteorites. They are cal ...read more
The fact that most humans spend most of their time indoors is not a subject of great debate. In contrast, archeologists agree that Neanderthals spent most of their time outdoors, so what were their living . Scientists have evidence dating Neanderthals to more than 520,000 years ago. They believe Neanderthals originated in Africa and then migrated to Europe. They went extinct around 40,000 years ago.They left little behind for scientists to analyze. Although some ancient skeletons have bee ...read more
