| Why sibling stars look alike: Early, fast mixing in star-birth clouds Posted: 31 Aug 2014 12:03 PM PDT Early, fast, turbulent mixing of gas within giant molecular clouds -- the birthplaces of stars -- means all stars formed from a single cloud bear the same unique chemical 'tag' or 'DNA fingerprint,' write astrophysicists. Could such chemical tags help astronomers identify our own Sun's long-lost sibling stars? |
| Changing global diets is vital to reducing climate change Posted: 31 Aug 2014 12:02 PM PDT Healthier diets and reducing food waste are part of a combination of solutions needed to ensure food security and avoid dangerous climate change, say the team behind a new study. |
| New type of cell movement discovered Posted: 28 Aug 2014 11:27 AM PDT Scientists have used an innovative technique to study how cells move in a three-dimensional matrix, similar to the structure of certain tissues, such as the skin. They discovered an entirely new type of cell movement whereby the nucleus helps propel cells through the matrix like a piston in an engine. |
| HIV Lessons from the Mississippi Baby Posted: 28 Aug 2014 11:26 AM PDT The news in July, 2014 that HIV had returned in a Mississippi toddler after a two-year treatment-free remission dashed the hopes of clinicians, HIV researchers and the public at large tantalized by the possibility of a cure. But a new commentary by two leading HIV experts argues that despite its disappointing outcome, the Mississippi case and two other recent HIV "rebounds" in adults, have yielded critical lessons about the virus' most perplexing — and maddening — feature: its ability to form cure-defying viral hideouts. |
