Red flag for repetitive stress injuries identified for first time in humans
03-06-2007 · EurekAlert!A new discovery paves the way for early detection of repetitive injuries like carpal tunnel and tendonitis -- a $20 billion annual problem - before the damage leads to disability and lost work days. For the first time in humans, Temple University researchers have identified early indicators of inflammation -- potential warning signs of damage caused by repetitive motion. Their findings are reported in the March issue of Clinical Science

- Stressed-out African naked mole-rats may provide clues about human infertility
07-01-2007 · EurekAlert!
Naked mole-rats could shed light on stress-related infertility in humans, the 23rd annual meeting of the European Society of Human Reproduction and Embryology will hear.Dr Chris Faulkes, a senior lecturer at the School of Biological & Chemical Sciences, Queen Mary, University of London, will tell the conference that the African naked mole-rat is at the extreme end of a continuum of socially-induced reproductive suppression among mammals.

- UGA researchers discover how human body fights off African parasite
09-06-2007 · EurekAlert!
A team of researchers led by biochemists at the University of Georgia propose that T. b. brucei actually does infect humans but that the infection triggers release of hemoglobin from red blood cells. Hemoglobin appears to "arm" the human innate immune system by binding to a small fraction of high density lipoprotein (HDL), or "good cholesterol." The hemoglobin-HDL complex then becomes a super toxin and clears the body of trypanosomes.

- Genome study places modern humans in the evolutionary fast lane
12-10-2007 · EurekAlert!
Countering a common theory that human evolution has slowed to a crawl or even stopped in modern humans, a new study examining data from an international genomics project describes the past 40,000 years as a time of supercharged evolutionary change, driven by exponential population growth and cultural shifts.

- Groups and grumps: Study identifies 'sociality' neurons
10-23-2006 · EurekAlert!
A University of California, San Diego study has for the first time identified brain cells that influence whether birds of a feather will, or will not, flock together. The research demonstrates that vasotocin neurons in the medial extended amygdala -- which are present in most animals, including humans -- respond differently to social cues in birds that live in colonies compared to their more solitary cousins.

- Latest IPCC report highlights need for integrated climate/human behavior models
04-06-2007 · EurekAlert!
How can humans adapt to climate change without adding even more stress to the environment? Scientists are now looking at ways to integrate the human dimension of climate change -- the choices we need to make to adapt to a changing global climate -- with the sophisticated climate prediction models used for the IPCC Assessment Reports. The goal: To evaluate the best ways forward.

- Researchers find earliest evidence for modern human behavior in South Africa
10-17-2007 · EurekAlert!
Evidence of early humans living on the coast in South Africa, harvesting food from the sea, employing complex bladelet tools and using red pigments in symbolic behavior 164,000 years ago, far earlier than previously documented, is being reported in the Oct. 18 issue of the journal Nature. The international team of researchers reporting the findings include Curtis Marean, a paleoanthropologist with the Institute of Human Origins at Arizona State University.

- Potential new way of treating inflammatory diseases identified
09-13-2007 · EurekAlert!
Scientists have shown for the first time that platelets, the cells needed for blood clotting, help white blood cells called neutrophils fight inflammation. The results of the study could lead to new anti-inflammatory compounds for the treatment of inflammatory vascular injury.
