Almost good enough to eat

...haracteristics may help explain human food taboos, say the researchers. Most of the species avoided for the ill include species high on the food chain. These fish are more likely to accumulate toxins. The prohibitions on these species may be biologically adaptive for the people, suggest Begossi and col...

Chimpanzee 'workshop' discovered in Congo

... University, and Steve Gulick of Wildland Security say that the Goualougo chimps use tools in different ways than previously observed. The study, funded in large part by WCS and National Geographic, relied on remote video cameras recording chimps using heavy sticks to punch holes in termite mounds, the...

Munching microbes could cleanse arsenic-contaminated groundwater

...arsenic builds to dangerous levels in groundwater, say researchers at the University of Illinois at Urbana-Champaign. Remediation may be as simple as stimulating certain microbes to grow. Arsenic contamination is a serious threat to human health. In the Ganges Delta of Bangladesh, for example, chronic ...

Solutions to stop fishermen returning dead and dying marine animals back into sea - study

...ne, writing in the academic journal Marine Policy, say fishermen should be given incentives not to return unwanted fish and other marine animals known as 'discards' back into the sea after they are caught in their trawlers' nets. The study focused on the North Sea, which is bordered by Norway and the E...

Humans and dolphins: If brain size is a measure, we're not that different

...long different paths," Marino says. "What the data say to me is that we, as humans, are not that special. Although we are highly encephalized [have large brains], it's not by much compared with cetaceans." The scientists investigated the fossil record of the toothed whales (which includes dolphins, po...

Academics work to help stressed-out cats

But the biggest stressor of all for a cat is when it doesn't get along with other cats in the house, studies have shown. Cat health professionals at the University's Hospital for Small Animals studied the lifestyles of a group...

Evidence that learning is consolidated during sleep

Also, the researchers say that they have shown for the first time that the activity level in the brain's learning center, the hippocampus, correlates with the improvement in memory performance when the subjects are tested the next day. According to Philippe Peigneux and his c...

Research to explore revolutionary gene sequencing: Threading the molecular needle

...en't yet encountered any fundamental problems that say this is impossible but we have encountered lots of challenges that still need to be solved. But this is what scientific research is about. We are making solid progress and every time a new problem has come up, we have found a way around it. This gran...

Hurricane damage creates pecan shortage

Pecan growers in Georgia and Alabama, two of the primary pecan growing areas were already expecting a light production year due to reduced nut set on many cultivars, said Ti...

Findings challenge Darwinian theory

DASH diet may do more than lower blood pressure

Gut microbes can open gates in fat cells

...at normally live in the gut can increase body fat, say researchers at Washington University School of Medicine in St. Louis. They found that gut microbes can open the "gates" fat uses to enter the body's fat cells. Using a two-pronged strategy, gut microbes first break down otherwise indigestible dietary...

Scientists pioneer biotech techniques to halt infestation of history, art treasures in tropics

UNU-BIOLAC, focussed on biotechnology in Latin America and the Caribbean, is breaking ground in the region by usin...

Scientists find acid rain an unlikely ally in the battle against a greenhouse gas

...hat are not always well understood. "That's not to say that acid rain is a good thing. Rather this study illuminates really well how we have to work to understand relationships among microscopic-to-global processes, at the same time that we attempt to represent them in relatively simple ways," Matthews s...

Powerful 'toolkit' developed for functional profiling of yeast genes

The toolkit, a combination of techniques developed by the Hopkins researchers and others, starts with a collection of almost 6,000 yeast strains, each missing a different gene, and allows researchers to identify genes whose coupled e...

New gene target found for common brain tumors in children

... planned, the researchers emphasize. Scientists say that gene amplification - a process in which cells make too many copies of a gene -- is one of the most reliable indicators of a gene's importance to cancer development. The Johns Hopkins team found Notch2 amplified in six of 40 (15 percent) medullo...

Reduced fish stocks linked to increased bushmeat trade, wildlife declines in W. Africa

"It's an ethical and good approach, but if the larger problem of wildlife decline is mainly a result of large-scale economic policies and pressures that cause the over-ex...

UCSD researchers find effective treatment for unusual fever syndrom caused by cold exposure

Remember when Grandma used to say 'don't go out in the cold; you'll get sick'? It turns out that she was right for a small number of people who have a condition called familial cold autoinflammatory syndrome (FCAS), in which individuals are afflicted by rash, fever, joint pain and f...
