New evidence of 'human' culture among primates

...the same way as we might use a hammer and anvil to crack nuts. Similar evidence of stone-based technology is found in the archaeological record of the earliest humans, and as more evidence emerges, it is hoped the ancient ancestry of human behaviour will become clear. ...

...opped because fewer people were selling sex to get crack cocaine as the decade went by. However, the syphilis rate rose by 19 percent between 2000 and 2003. During that period, the rates among women continued to slide ?by 53 percent ?while rates among men jumped by 62 percent. While syphilis statisti...

BGSU biologist trying to crack microscopic code

... Bowling Green State University biologist wants to crack the communication code of proteins, especially the ones whose "talking" aids and abets disease. "Proteins interact; they 'talk' to each other," the associate professor says. "It's how they know what to do, and it's how most of the things that need t...

Use of stone hammers sheds light on geographic patterns of chimpanzee tool use

Scientists crack code for motor neuron wiring

... technical advance that enabled the researchers to crack this code. Using these antibodies, Dasen and colleagues pinpointed the pattern of expression of each protein within the set of motor neurons that project to limb muscles. "Once we had these reagents, we were able to obtain the high resolution maps of...

Protein helps regulate the genes of embryonic stem cells

... research. Researchers five decades ago worked to crack the genetic code, the nucleic acid sequence of As, Cs, Gs and Ts making up the DNA of genes. Today, Magnuson's team is trying to unravel a different, newly appreciated mode of inheritance: epigenetics. "Epigenetic inheritance is heritable informatio...
