With HMGB1's help, cells dine in

Cells often respond to hunger or stress by digesting some of their contents. The process, known as autophagy, helps free nutrients and clean up cytoplasmic trash such as worn-out organelles and misshapen proteins. A team led by [...]

Artificial life? Synthetic genes 'boot up' cell

They hope to use their stripped-down version of a bacterium to learn how to engineer custom-made microbes. But some groups worried the technology might be used to make biological weapons and President Barack Obama asked his bioethics a [...]

Scientists find nerve cells responsible for itch

Researchers have found specific nerve cells responsible for itchiness, a discovery that could lead to better treatments for skin conditions. Experiments on mice show they have nerve cells that convey only an itch sensation -- contradicting [...]

U.S. stem cell research rules ease some restrictions

The U.S. government released new rules on Monday governing federally funded research on human embryonic stem cells, loosening some ethical requirements that scientists said could have cost them a decade of work. The rules, which take effec [...]

Scientists Deconstruct Cell Division

Scientists have tried for years to unravel the process of spindle assembly. Now, researchers at Carnegie's Department of Embryology have found that two proteins— dynein and Nudel—involved in other cell-division functions, are es [...]
