Ancient Earth's Magnetic Field Was Structured Like Today's Two-pole Model

Scientists have shown that, in ancient times, the Earth's magnetic field was structured like the two-pole model of today, suggesting that the methods geoscientists use to reconstruct the geography of early land masses on the globe are accurate. The findings may lead to a better understanding of historical continental movement, which relates to changes in...

Aspirin Misuse May Have Made 1918 Flu Pandemic Worse

The devastation of the 1918-1919 influenza pandemic is well known, but a new article suggests a surprising factor in the high death toll: the misuse of aspirin. AThe article sounds a cautionary note as present day concerns about the novel H1N1 virus run high.

Herschel Views Deep-space Pearls On A Cosmic String

Europe's Herschel space telescope has delivered spectacular vistas of cold gas clouds lying near the plane of the Milky Way, revealing intense, unexpected activity. The dark, cool region is dotted with stellar factories, like pearls on a cosmic string.

Livestock Can Help Rangelands Recover From Fires

Scientists in Oregon found that rangelands that have been grazed by cattle recover from fires more effectively than rangelands that have been protected from livestock. These surprising findings could impact management strategies for native plant communities where ecological dynamics are shifting because of climate change, invasive weeds and other...

New Plywood Glue Made With Corn

After the oil is extracted from corn germ meal, the corn germ is typically fed to poultry and other livestock animals. But a new, value-added use could be on tap for this "leftover." Researchers have determined that corn germ can be used as a protein extender for plywood...

Pathways Of Movement Of Sudden Oak Death Pathogen Described

The pathogen that causes sudden oak death disease in California has a different genetic fingerprint than fungal strains found in nurseries in Oregon and Washington, according to scientists. This discovery will allow scientists to distinguish infections in other states as likely having originated from either California or the Pacific...

Quick Rebound From Marine Mass Extinction Event, New Findings Show

Researchers have done the most detailed analysis ever of a layer of sediments deposited during and immediately after the asteroid impact 65 million years ago that wiped out the dinosaurs and 80 percent of Earth's marine life. They found that at least some forms of microscopic marine life -- the so-called "primary producers," or photosynthetic organisms such as algae and cyanobacteria in the ocean...

Using Synthetic Evolution To Study The Brain: Key Part Of Neurons Modeled On Computer

The human brain has evolved over millions of years to become a vast network of billions of neurons and synaptic connections. Understanding it is one of humankind's greatest pursuits. But to understand how the brain processes information, researchers must first understand the very basics of neurons -- even down to how proteins inside the neurons act to change the neuron's voltage. To do so requires...

Where's The Science? The Sorry State Of Psychotherapy

The prevalence of mental health disorders in this country has nearly doubled in the past 20 years. Who is treating all of these patients? Clinical psychologists and therapists are charged with the task, but many are falling short by using methods that are out of date and lack scientific rigor, according to a new...

Ancient Rainforests Resilient To Climate Change

Climate change wreaked havoc on the Earth’s first rainforests but they quickly bounced back, scientists reveal. The findings are based on spectacular discoveries of 300-million-year-old rainforests in coal mines in Illinois, USA.

Putting The Squeeze On Sperm DNA: Streamlined Sperm Offer New Way To Read Histone Code

In the quest for speed, olympic swimmers shave themselves or squeeze into high-tech super-suits. In the body, sperm are the only cells that swim and, as speed is crucial to fertility, have developed their own ways to become exceptionally streamlined. Scientists in Europe have been studying the secrets of speedy sperm. Their work shows how a protein only found in developing sperm cells, Brdt,...

Light Shed On Kidney Repair And Disease

Researchers have shed new light on the microscopic antennas in the kidney that are involved in the organ's repair process. The work may be a crucial step towards a cure for polycystic kidney disease, a potentially fatal disease that affects more than one in 1000 people.

Juvenile Bluefin Tuna Found To Dive To Depths Of More Than 1000 Meters

A bluefin tuna, tagged by researchers in August 2008, was caught a year later by a professional bait boat off the coast of northern Spain. The animal had internally implanted electronic tag which enabled its migratory movements and the depth of these, amongst other data, to be obtained. First estimations of the geographical location of the recovered tag revealed that this fish had undertaken...

Sexually Satisfied Women Have Better General Well-being, Study Finds; Older Women Score Higher Than Younger Women

Pre- and post-menopausal women who self-rated themselves as being sexually satisfied had a higher overall psychological well-being score and scores for "positive well-being" and "vitality," compared with sexually dissatisfied women in a study of 295 women sexually active more than twice a month. The study also uncovered a positive association between age and well-being, but a negative association...
