Scientists use manufacturing methods to reconstruct mastodon

...te 1980s, he found the first evidence that Ice Age hunters in North America butchered mastodons and preserved the meat by storing it underwater.

Though bushmeat hunting and consumption may be a significant factor in viral transmission in Africa, Jones-Engel says, people in Asia have many other contexts in which they come into contact with p...

Study shows big game hunters, not climate change, killed off sloths

Seal rookeries could provide a reliable food source for endangered California condors, study finds

...Unfortunately, many of these animals are killed by hunters using lead shot, which is highly toxic to scavengers. "Condors are obligate scavengers, so they'll feed on anything that's there," Chamberlain says. "If they consume just a small lead fragment, it can kill them." For the PNAS study, the researcher...

Performing monkeys in Asia carry viruses that could jump species to humans

However, in Asia other forms of primate/human contact, among them urban monkey performances, may be more prevalent than bushmeat hunting. Asia has a long history of performing monkeys, and initial...

Alleged 40,000-year-old human footprints in Mexico much, much older than thought

... at 40,000 years old. They hypothesized that early hunters walked across ash freshly deposited near a lake by volcanoes that are still active in the area around Puebla, Mexico. The so-called footprints, subsequently covered by more ash and inundated by lake waters, eventually turned to rock. But Paul Renne,...

New strategy rapidly identifies cancer targets

...and Yale University. Traditionally, cancer-gene hunters have scanned the genome looking for mutations that trigger out-of-control cell growth. Druker tried this approach, but found it wanting. "We were doing some high-throughput DNA sequencing, and we weren't really finding much," he said. Instead, the...

Ancient DNA traces the woolly mammoth's disappearance
