Scientists have taken microscopic images revealing that the protein ties tethering cells together are severed in lung cancer cells.

Egg and sperm race: Scientists create precursors to human egg and sperm

Posted: 25 Dec 2014 11:35 AM PST

Scientists have created primordial germ cells -- cells that will go on to become egg and sperm -- using human embryonic stem cells. Although this had already been done using rodent stem cells, this is the first time this has been achieved efficiently using human stem cells.

Prenatal exposure to common household chemicals linked with substantial drop in child IQ

Posted: 10 Dec 2014 11:08 AM PST

Children exposed during pregnancy to elevated levels of two common chemicals found in the home -- di-n-butyl phthalate and di-isobutyl phthalate -- had an IQ score, on average, more than six points lower than children exposed at lower levels, according to researchers. The study is the first to report a link between prenatal exposure to phthalates and IQ in school-age children. While avoiding all phthalates in the United States is for now impossible, the researchers recommend that pregnant women take steps to limit exposure by not microwaving food in plastics, avoiding scented products as much as possible, including air fresheners, and dryer sheets, and not using recyclable plastics labeled as 3, 6, or 7.

Empathy represses analytic thought, and vice versa: Brain physiology limits simultaneous use of both networks

When the brain's analytic network is engaged, our ability to appreciate the human cost of our action is repressed, researchers have found. The study shows for the first time that we have a built-in neural constraint on our ability to be both empathetic and analytic at the same time.
