In efforts to understand what influences life span, cancer and aging, scientists are building roadmaps to navigate and learn about cells at the molecular level. To survey previously uncharted territory, a team of researchers at UW-Madison created an "atlas" that maps more than 1,500 unique landmarks within mitochondria that could provide clues to the metabolic connections between caloric restriction and aging. The map, as well as the techniques used to create it, could lead to a better...

Stress During Infancy Affects Brain Development Of Females
2012-11-13 06:16:34

Connie K. Ho for redOrbit.com — Your Universe Online Researchers from the University of Wisconsin-Madison recently discovered that early family stress during infancy could be related to changes that occur in the daily brain function and anxiety of teenage girls. The data was pooled from a population study that looked at the relationship between stress and the developmental pathway of the brain. For female infants who lived in homes with stressed out mothers, they were more likely...

April Flowers for redOrbit.com - Your Universe Online “Like the generations of leaves, the lives of mortal men. Now the wind scatters the old leaves across the earth, now the living timber bursts with the new buds and spring comes round again. And so with men: as one generation comes to life, another dies away.” “• Homer, The Iliad The city-state of Troy is the stuff of legends, with mythical heroes, women of unsurpassed beauty and the fabled wooden Trojan Horse....

Biology Notes Help Recreate Sound Of Times Past
2012-09-19 10:28:48

Brett Smith for redOrbit.com - Your Universe Online For urban and suburban dwellers, the cutting drone of a jet engine or the swoosh of a passing car is more familiar than any bird´s song or chipmunk´s chatter. The wheels of progress have slowly changed modern man´s soundscape, for better or worse, as the industrial revolution forges ahead. To recreate the aural experience of an earlier time, two ecologists have turned to the 70-year-old notes of biodiversity pioneer Aldo...

Human papillomavirus (HPV) has long been implicated in cervical cancer, but details of how it happens have remained a mystery. Now researchers at the University of Wisconsin-Madison have found that a single HPV protein is required for cervical cancer and even pre-cancer growths in the cervix to survive. In anticipation of a clinical trial in humans, the scientists and their collaborators are moving quickly to test if a gene-silencing technique could cripple the protein and eliminate...

Acinetobacter baumanni, a pathogenic bacterium that is a poster child of deadly hospital acquired infections, is one tough customer. It resists most antibiotics, is seemingly immune to disinfectants, and can survive desiccation with ease. Indeed, the prevalence with which it infects soldiers wounded in Iraq earned it the nickname "Iraqibacter." In the United States, it is the bane of hospitals, opportunistically infecting patients through open wounds, catheters and breathing tubes. Some...

Printed Photonic Crystal Mirrors Shrink Down To Size On-Chip Lasers
2012-07-23 09:18:30

Electrical engineers at The University of Texas at Arlington and at the University of Wisconsin-Madison have devised a new laser for on-chip optical connections that could give computers a huge boost in speed and energy efficiency. The team published its findings on July 22, 2012 in Nature Photonics. At just 2 micrometers in height – smaller than the width of a human hair – the surface-emitting laser's vastly lower profile could make it cheaper and easier for manufacturers...

Greenland Ice Not A Reliable Model For Younger Dryas Period
2012-06-27 10:08:54

Brett Smith for redOrbit.com Ice samples that profile Greenland glaciers have long been used to give climate scientists historical temperature data, but those samples could be misleading, according to a new study published Monday in the Proceedings of the National Academy of Sciences. A team led by University of Wisconsin-Madison researchers found that the data gathered from the ice cores around Greenland varies greatly from other records of Northern Hemisphere temperatures during the...
