A researcher has come up with a rule that connects channel belts to river patterns, finding that, in general, the more channels a river has, the narrower its channel belt. Since the physics shaping rivers is the same over time and place, the rule should hold for ancient rivers and...
Rural areas near coast will bear the brunt of U.S. sea-level rise
A new analysis using highly detailed elevation maps of the Chesapeake Bay suggests that North America's extensive areas of low-lying rural land will allow coastal marshes to persist or even expand as salty water creeps upward into what are now forests and farmland.
A warming climate decreases microbial diversity
Researchers conducted an eight-year experiment that found that climate warming played a predominant role in shaping microbial biodiversity, with significant negative effect.
Hidden in plain sight: Biologists say southern right whale habitat choice is key to keeping young calves safe
While researchers have speculated that the up to 50-foot-long whales choose shallow, coastal locations for lack of predators and warmer and calmer waters, a team of biologists recently uncovered a new potential motive.
Cats’ strange reactions to catnip make it a better insect repellent
Anyone who has seen a cat experience catnip knows that it makes them go a bit wild -- they rub in it, roll on it, chew it, and lick it aggressively. It is widely accepted that this plant, and its Asian counterpart, silvervine, have intoxicative properties, but this might not...
Panthers now number one predator of white-tailed deer in Southwest Florida
A new study found Florida panthers are the No. 1 cause of mortality for white-tailed deer in Southwest Florida. The researchers set out to get a better picture of what factors most affect the survival of Florida's white-tailed deer, the most popular game species in the state and a key...
Genes reveal coffee is safe during pregnancy, study suggests
Researchers have used genetics to analyze coffee drinking behavior, and their findings show limited coffee consumption during pregnancy didn't increase the risk of miscarriage, stillbirth or premature birth.
New fire shelter prototypes could buy time for wildfire firefighters
Temperatures inside new wildfire shelter prototypes remained within survival limits for longer, and the shelters took longer to break open, compared with an industry standard.
Researchers discover mechanism linking mutations in the ‘dark matter’ of the genome to cancer
Many sections of the non-coding region of the human genome play a key role in regulating gene activity. But the relationship between non-coding mutations and cancer risk has been a mystery. New research sheds light on that mystery, providing clues that may link mutations to epigenetic changes, and may point...
Could used beer yeast be the solution to heavy metal contamination in water?
A new study finds inactive yeast could be effective as an inexpensive, abundant, and simple material for removing lead contamination from drinking water supplies. The approach should be efficient and economic, even down to part-per-billion levels of contamination.
