| Transcription factor Lyl-1 critical in producing early T-cell progenitors Posted: 08 Jul 2012 01:23 PM PDT A transcription factor called Lyl-1 is necessary for production of the earliest cells that can become T-cells, critical cells born in the thymus that coordinate the immune response to cancer or infections, new research shows. |
| New advanced electronics? Unprecedented subatomic details of exotic ferroelectric nanomaterials Posted: 08 Jul 2012 01:23 PM PDT Scientists have described a technique revealing unprecedented details about the atomic structure and behavior of exotic ferroelectric materials, which are uniquely equipped to store digital information. This research could usher in a new generation of advanced electronics. |
| Exome sequencing of health condition extremes can reveal susceptibility genes Posted: 08 Jul 2012 01:23 PM PDT Comparing DNA from patients at the best and worst extremes of a health condition can reveal genes for resistance and susceptibly. This approach discovered rare variations in the DCTN4 gene among cystic fibrosis patients prone to early, chronic airway infections. The gene codes for part of a molecular motor that moves microbes along a cellular conveyer belt to their annihilation. Similar "testing the extremes" strategies may uncover genes behind more common traits -- healthy and unhealthy hearts, leaness and obesity, and normal and high blood pressure. |
| Melanoma: Molecule in immune system could help treat dangerous skin cancer Posted: 08 Jul 2012 01:23 PM PDT Researchers have made a groundbreaking discovery that will shape the future of melanoma therapy. The high expression of a cell-signaling molecule, known as interleukin-9, in immune cells has been found to inhibit melanoma growth. |
| Urinary infections steal from hosts' defense arsenals Posted: 08 Jul 2012 01:22 PM PDT Humans have known for centuries that copper is a potent weapon against infection. New research shows that the bacteria that cause serious urinary tract infections "know" this, too, and steal copper to prevent the metal from being used against them. |
| What happens when we sunburn: Red is RNA damage to skin cells Posted: 08 Jul 2012 01:22 PM PDT The biological mechanism of sunburn – the reddish, painful, protective immune response from ultraviolet (UV) radiation – is a consequence of RNA damage to skin cells, report researchers. |
