More than a third of marriages between 2005 and 2012 began online, according to new research at the University of Chicago, which also found that online couples have happier, longer marriages.
Although the study did not determine why relationships that started online were more successful, the reasons may include the strong motivations of online daters, the availability of advance screening and the sheer volume of opportunities online. (more…)
Sugar isn’t always sweet to German cockroaches, especially to the ones that avoid roach baits.
In a study published May 24 in the journal Science, North Carolina State University entomologists show the neural mechanism behind the aversion to glucose, the simple sugar that is a popular ingredient in roach-bait poison. Glucose sets off bitter receptors in roach taste buds, causing roaches to avoid foods that bring on this taste-bud reaction. This aversion has a genetic basis and it eventually spreads to offspring, resulting in increasingly large groups of cockroaches that reject glucose and any baits made with it.
In normal German cockroaches, glucose elicits activity in sugar gustatory receptor neurons, which react when exposed to sugars like glucose and fructose – components of corn syrup, a common roach-bait ingredient. Generally, roaches have a sweet tooth for these sugars. (more…)
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. (more…)
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…)
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…)
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.

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. (more…)
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. (more…)
