A more effective method for closing gaps in atomically small wires has been developed by University of Illinois researchers, further opening the doors to a new transistor technology.
Two studies in mice add to the evidence that the phthalate DEHP, a plasticizing agent used in auto upholstery, baby toys, building materials and many other consumer products, can undermine female reproductive health, in part by disrupting the growth and function of the ovaries.
When scientists exposed pregnant mice to levels of bisphenol A equivalent to those considered safe in humans, three generations of female mouse offspring experienced significant reproductive problems, including declines in fertility, sexual maturity and pregnancy success, the scientists report in the journal Toxicology and Applied Pharmacology.
A new study co-written by a University of Illinois expert in intellectual property law demonstrates that the value of creative works in the public domain such as books, images and music can be estimated at least as precisely as the value of commercially available copyrighted works.
Scientists have found a signal in the brain that reflects young children’s aversion to members of the opposite sex (the “cooties” effect) and also their growing interest in opposite-sex peers as they enter puberty. These two responses to members of the opposite sex are encoded in the amygdala, the researchers report.
An ancient human skull and a jawbone found a few meters apart in a cave in northern Laos add to the evidence that early modern humans were physically quite diverse, researchers report in PLOS ONE.
