Hidden Wildfires Taking Big Toll on Amazon Rainforest

Using an innovative satellite technique, NASA scientists have determined that a previously unmapped type of wildfire in the Amazon rainforest is responsible for destroying several times more forest than has been lost through deforestation in recent years.

In the southern Amazon rainforest, fires below the forest treetops, or “understory fires,” have been hidden from view from NASA satellites that detect actively burning fires. The new method has now led to the first regional estimate of understory fire damages across the southern Amazon. (more…)

Maintaining Positivity, Motivation Can Help Job Search Process, MU Researcher Finds

COLUMBIA, Mo. – Currently, many recent college graduates still face the daunting task of searching for a job. While the job search process can be long and exhausting, a University of Missouri researcher has found that maintaining positivity and staying motivated can lead to a more successful job search.

“The search for a job can be stressful time in anyone’s life, especially first-time college graduates,” said Daniel Turban, professor of management at the MU Trulaske College of Business. “Job searching isn’t rewarding until the end of the search when a job is actually secure.” (more…)

Northern hemisphere losing last dry snow region, says CU study

Last July, something unprecedented in the 34-year satellite record happened: 98 percent of the Greenland Ice Sheet’s surface melted, compared to roughly 50 percent during an average summer. Snow that usually stays frozen and dry turned wet with melt water. Research led by the Cooperative Institute for Research in Environmental Sciences now shows last summer’s extreme melt could soon be the new normal.

“Greenland is warming rapidly, and such ice-sheet-wide, surface-melt events will occur more frequently over the next couple of decades,” said Dan McGrath, a University of Colorado Boulder doctoral student who works at CIRES. McGrath is lead author of a paper published online May 20 in Geophysical Research Letters and which reports a significant warming trend on the Greenland Ice Sheet. (more…)

Female company directors are better judges of longer-term company performance

Groundbreaking research by the University of Exeter Business School reveals that female company directors defy negative gender stereotyping by astutely valuing future company performance.

The stock market responds more positively to trades made by male directors in their own company stock than their female counterparts, new research reveals. 

However, over the longer term (3 – 12 months), returns made by female directors’ on trades in their own company stock are at least equal to, or exceed, those of their male counterparts.

The study by the University of Exeter Business School analysed over 80,000 legal trades made by directors of companies listed on the London and AIM stock exchanges. It is commonly assumed that when a director buys shares in their own company, they believe it to be undervalued by the stock market and this frequently leads to investors buying more stocks in that company and pushing up the share price.

Scientists sequence genome of ‘sacred lotus,’ which likely holds anti-aging secrets

A team of 70 scientists from the U.S., China, Australia and Japan today reports having sequenced and annotated the genome of the “sacred lotus,” which is believed to have a powerful genetic system that repairs genetic defects, and may hold secrets about aging successfully. The scientists sequenced more than 86 percent of the nearly 27,000 genes of the plant, Nelumbo nucifera, which is revered in China and elsewhere as a symbol of spiritual purity and longevity.

Tactics of new Middle East virus suggest treating by altering lung cells’ response to infection

A new virus that causes severe breathing distress and kidney failure elicits a distinctive airway cell response to allow it to multiply.  Scientists studying the Human Coronavirus-Erasmus Medical Center, which first appeared April 2012 in the Middle East, have discovered helpful details about its stronghold tactics.

Their findings predict that certain currently available compounds might treat the infection.  These could act not by killing the virus directly but by keeping lung cells from being forced to create a hospitable environment for the virus to reproduce.  The researchers caution that their lab and computer predictions would need to be tested to see if the drugs work clinically.

Injured at the beach

Emergency department visits from beach injuries are common, study finds

Injuries to people swimming at the beach are common and severe, according to an ongoing study by the Delaware Sea Grant College Program and Beebe Medical Center

A total of 1,121 injuries requiring emergency department treatment were recorded in Delaware during the past three summers for patients hurt by ocean waves. Injuries range from simple sprains and strains to extremity fractures, blunt organ trauma and fractures of the cervical spine. There were three fatalities attributed to surf zone injuries during the study period. The most common ailments were broken collarbones, dislocated and separated shoulders, neck pain, and ankle and knee sprains.  (more…)

Migration No Longer Best Strategy for Yellowstone Elk

LARAMIE, Wyo. — Migratory elk are coming back from Yellowstone National Park with fewer calves due to drought and increased numbers of big predators – two landscape-level changes that are reducing the benefits of migration with broader implications for conservation of migratory animals, according to a new study published in the journal Ecology.

The new study by the Wyoming Cooperative Fish and Wildlife Research Unit – a joint program involving U.S. Geological Survey, the University of Wyoming, and the Wyoming Game and Fish Department, describes a long-term decline in the number of calves produced annually by the Clarks Fork herd, a population of about 4000 elk whose migrants travel annually between winter ranges near Cody, Wyoming and summer ranges within Yellowstone National Park.  Migratory elk experienced a 19 percent depression in rates of pregnancy over the four years of the study and a 70 percent decline in calf production over 21 years of monitoring by the WGFD, while the elk that did not migrate, known as resident elk, in the same herd experienced high pregnancy and calf production and are expanding their numbers and range into private lands outside of the park.
