Chimps dig up clues to human past?
11-12-2007 · EurekAlert!One of the keys enabling the earliest human ancestors to trade a forest home for more open country may have been the ability to gather underground foods. Now a team of scientists reports for the first time that in Tanzania our closest living relatives, chimpanzees, are using sticks and pieces of bark to dig for edible roots, tubers and bulbs.

- Past greenhouse warming events provide clues to what the future may hold
02-15-2008 · EurekAlert!
Scientists studying an extreme period of global warming 55 million years ago are piecing together an increasingly detailed picture of its causes and consequences. Their findings describe what may be the best analog in the geologic record for the global changes likely to result from continued carbon dioxide emissions from human activities.

- Plant viruses from past provide ecological clues
10-08-2007 · EurekAlert!
Taking the medical history of a grassland may seem a bit esoteric. However, scientists have discovered plant viruses from as early as 1917 containing information crucial not only for plant scientists, but for those in ecology, human health and bioterrorism. Carolyn Malmstrom at Michigan State University isolated historical viral RNA sequences in native and invasive grasses revealing a complex picture of struggles of species, interactions of insects and implications for the ways viruses behave today.

- Researchers propose reason for severe side-effects of Northwick Park clinical trial
01-25-2007 · EurekAlert!
A possible reason why the Northwick Park clinical trial of the drug TGN1412 in the UK caused multiple organ failure in human volunteers is revealed in research presented today at a conference near Paris. The research shows that stimulating the molecule CD28 on cells that mediate the immune response, known as T cells, can have an adverse effect if these immune cells have been activated and altered by infection or illness in the past.

- Comparing Chimp, Human DNA
10-13-2006 · ScienceDaily
Most of the big differences between human and chimpanzee DNA lie in regions that do not code for genes, according to a new study. Instead, they may contain DNA sequences that control how gene-coding regions are activated and read.

- Dragonfly's metabolic disease provides clues about human obesity
11-20-2006 · EurekAlert!
Parasite-infected dragonflies suffer the same metabolic disorders that have led to an epidemic of obesity and type 2 diabetes in humans, according to research to be published in the Proceedings of the National Academy of Science. The discovery expands the known taxonomic breadth of metabolic disease and suggests that the study of microbes found in human intestines may provide a greater understanding of the root causes of human metabolic dysfunction.

- Evidence from ancient European graves raises questions about ritual human sacrifice
05-29-2007 · EurekAlert!
A fascinating new paper explores ancient multiple graves and raises the possibility that hunter gatherers in what is now Europe may have practiced ritual human sacrifice. This practice -- well-known in large, stratified societies -- supports emerging research that argues that the level of social complexity reached in the distant past by groups of hunter gatherers was well beyond that of many more recent small bands of modern foragers.

- Mutation may cause inherited neuropathy
12-25-2007 · EurekAlert!
Mutations in a protein called dynein, required for the proper functioning of sensory nerve cells, can cause defects in mice that may provide crucial clues leading to better treatments for a human nerve disorder known as peripheral neuropathy, which affects about three percent of all those over age 60.

- Comparing chimp and human DNA
10-12-2006 · EurekAlert!
Scientists look to the chimpanzee genome to better understand our own. In a new study, researchers used comparative genomics to investigate the properties of a set of 202 carefully screened "highly accelerated regions." They searched for stretches of DNA that were highly conserved between chimpanzees, mice and rats, comparing those sequences to the human genome sequence in order to unravel the evolutionary forces at work behind the human genome's fastest evolving regions.

- Tool-wielding chimps provide a glimpse of early human behavior
11-12-2007 · EurekAlert!
Chimpanzees inhabiting a harsh savanna environment and using bark and stick tools to exploit an underground food resource are giving scientists new insights to the behaviors of the earliest hominids who, millions of years ago, left the African forests to range the same kinds of environments and possibly utilize the same foods.
