In the northeastern corner of Minnesota stand towering groves of red pine trees stretching some 80 feet into the sky.

But these red pine groves could eventually vanish from Minnesota’s Boundary Water Canoe Area if what we usually view as a foe to forests — fire — fails to sweep the terrain occasionally, says a new study from the University of Wisconsin-Madison.

“The big, natural groves of red pine are one of the most unique features of the BWCA. But, because of fire suppres

Industrial fishing poses the biggest threat to life and fin for sharks, dolphins and billfish that inhabit the tropical and northern Pacific Ocean, says a new study forecasting the effects of commercial fishing on ocean ecosystems.

Though not targeted by the fishing industry, some ocean species often get caught unintentionally in nets or lines used to catch tuna and other commercially valuable fish, says a study presented to scientists today, Aug. 5, at the annual meeting of the Ecological

First amphetamine-based long-acting stimulant offers all-day symptom control in children
A research team led by a Massachusetts General Hospital investigator has found that a long-acting form of the stimulant medication Adderall is effective in controlling symptoms of attention-deficit/hyperactivity disorder (ADHD) in children when taken in a single morning dose. The standard form of Adderall, which is made up of several amphetamine-based drugs, is only effective for four hours. This new f

A physical map of the genetic makeup of a mouse – the mouse genome – is 98 percent complete and is being released online by the journal Nature. Researchers at the Genome Sequencing Center at Washington University School of Medicine in St. Louis played a major role in the international effort, as they did in the sequencing and mapping of the human genome.

“The mouse plays a vital role in research on human biology and disease,” says John D. McPherson, Ph.D., associate professor of genetics a

Luckily for us, the economically devastating Karnal bunt fungus needs personal ads and singles bars more than we do.

Airborne spores from the fungus, which damages wheat crops, are limited in how well they can start new infections over long distances, according to the findings from a Kansas State University project.

A phenomenon known as the Allee effect occurs when a small population of a species spread over a large area has little success in reproduction. The reason is that when

Supermassive black holes at the hearts of large galaxies merge when their host galaxies do, say Professor David Merritt of Rutgers University, New Jersey, and Professor Ron Ekers of CSIRO’s Australia Telescope National Facility in Sydney, Australia.

The astronomers make their claim in a paper published online in Science Express on August 1 [U.S. time].

Merritt and Ekers’ model is the strongest evidence to date that the black holes’ mutual attraction ends in an embrace rather than
