Rusting iron can be its own worst enemy: Simulations show iron catalyzes corrosion in ‘inert’ carbon dioxide
Iron that rusts in water theoretically shouldn’t corrode in contact with an “inert” supercritical fluid of carbon dioxide. But it does. The reason has eluded materials scientists to now, but a team at Rice University has a theory that could contribute to new strategies to protect iron from the environment. Materials theorist Boris Yakobson and […]
River flows linked to the ups and downs of imperiled Chinook salmon population
A study led by Simon Fraser University researchers has discovered that sufficient water flows during summer can be critical to a Chinook salmon population in the interior of British Columbia. The researchers investigated how water flows in the Nicola watershed affect early summer-run Chinook salmon. The team used an advanced time-series model to understand 22 […]
Babies can tell who has close relationships based on one clue: Saliva: Sharing food and kissing are among the signals babies use to interpret their social world
Learning to navigate social relationships is a skill that is critical for surviving in human societies. For babies and young children, that means learning who they can count on to take care of them. MIT neuroscientists have now identified a specific signal that young children and even babies use to determine whether two people have […]
Drug mimics beneficial effects of fasting in mice: Blocking arginine metabolism leads to improved metabolic health, weight loss
An investigational cancer drug that starves tumors of their energy supply also shows evidence of improving whole body metabolism, leading to improved weight control, according to a new study in mice from researchers at Washington University School of Medicine in St. Louis. The findings are published in the journal Cell Reports Medicine. In a group […]
Hubble finds a black hole igniting star formation in a dwarf galaxy
Often portrayed as destructive monsters that hold light captive, black holes take on a less villainous role in the latest research from NASA’s Hubble Space Telescope. A black hole at the heart of the dwarf galaxy Henize 2-10 is creating stars rather than gobbling them up. The black hole is apparently contributing to the firestorm […]
When graphene speaks, scientists can now listen: Brothers in Rice lab find audio from graphene production contains valuable data
It may be true that seeing is believing, but sometimes hearing can be better. Case in point: Two brothers in a Rice University laboratory heard something unusual while making graphene. Ultimately, they determined the sound itself could give them valuable data about the product. The brothers, John Li, a Rice alumnus now studying at Stanford […]
What Are 5 of the Main Symptoms of OCD?
Obsessive-compulsive disorder (OCD) is characterized by distressing and repetitive thoughts (obsession) that often compels a person to perform a repetitive action or behavior (compulsion). Symptoms of OCD vary from person to person, and doctors usually categorize them into specific groups. 5 main symptoms of OCD 1. Symmetry OCD symptoms OCD often presents with an urge […]
Engineers discover method to create upward water fountain in deep water: Fountain created by lasers, Marangoni Effect is the cause
A pair of University of Houston engineers has discovered that they can create upward fountains in water by shining laser beams on the water’s surface. Jiming Bao, professor of electrical and computer engineering at UH, and his postdoctoral student Feng Lin, attribute the finding to a phenomenon known as the Marangoni effect, which causes convection […]
