UD’s McCarthy part of group that films rare striped rabbit in Sumatra
With cameras set up in Sumatra looking for medium- and small-sized wild cats, such as leopards, a research group involving the University of Delaware’s Kyle McCarthy, found images of something else entirely — a rabbit. Not just any ordinary rabbit, but a Sumatran striped rabbit, one of the world’s rarest species and one that had been captured on film only three times before. (more…)
Environmental change is the selective force that preserves adaptive traits in organisms and is a primary driver of evolution. However, it is less well known that evolutionary change in organisms also trigger fundamental changes in the environment.
Yale University researchers found a prime example of this evolutionary feedback loop in a few lakes in Connecticut, where dams built 300 years ago in Colonial times trapped a fish called the alewife.
In a study published May 23 in the journal Proceedings of the Royal Academy B, the Yale team describes how this event fundamentally changed the structure of the alewife and, with it, the water flea that the alewife feeds upon and the food chain that supports them both. (more…)
The first overt indications of the impending global financial crisis manifested themselves in August 2007, when BNP Paribas announced it was severing ties with three hedge funds specializing in mortgage debt for American real estate properties. The crisis was exacerbated by the immediate freeze on credit by banks to their customers – and to each other. The crisis came to a head in 2008 when the United States government refused to rescue investment firm Lehman Brothers from financial collapse. Subsequent actions by the American government and by foreign governments, as well as actions taken by commercial enterprises world wide, have been focused on repairing the financial damage to sovereign economies and to individuals thrown out of work – and out of their homes.

Pollination could be a chaotic disaster. With hundreds of pollen grains growing long tubes to ovules to deliver their sperm to female gametes, how can a flower ensure that exactly two fertile sperm reach every ovule? In a new study, Brown University biologists report the discovery of how plants optimize the distribution of pollen for successful reproduction.
PROVIDENCE, R.I. [Brown University] — Next Mother’s Day, say it with an evolved model of logistical efficiency — a flower. A new discovery about how nature’s icons of romance manage the distribution of sperm among female gametes with industrial precision helps explain why the delicate beauties have reproduced prolifically enough to dominate the earth.
In pollination, hundreds of sperm-carrying pollen grains stick to the stigma suspended in the middle of a flower and quickly grow a tube down a long shaft called a style toward clusters of ovules, which hold two female sex cells. This could be a chaotic frenzy, but for the plant to succeed, exactly two fertile sperm should reach the two cells in each ovule — no more, no less. No ovule should be left out, either because too many tubes have gone elsewhere, or because the delivered sperm don’t work. (more…)

Global warming villain CO2 may have a surprisingly green future
The next frontier in the search for renewable energy lies less than two miles from where you are now.
Unless you’re reading this on the International Space Station.
Geothermal heat a mile or two deep in Earth’s crust is a potential source of energy that could be tapped by an unlikely carrier: carbon dioxide (CO2), the central villain in global warming. That energy, unlike solar and wind, could be easily turned on and off without the intermediate step of being stored in a battery. And it would be constant and reliable. (more…)
CEOs embark on a new era of leadership as they embrace a more connected culture
ARMONK, N.Y. – A new IBM study of more than 1,700 Chief Executive Officers from 64 countries and 18 industries worldwide reveals that CEOs are changing the nature of work by adding a powerful dose of openness, transparency and employee empowerment to the command-and-control ethos that has characterized the modern corporation for more than a century.
The advantages of the fast-moving trend are clear. According to the IBM CEO study, companies that outperform their peers are 30 percent more likely to identify openness – often characterized by a greater use of social media as a key enabler of collaboration and innovation – as a key influence on their organization. Outperformers are embracing new models of working that tap into the collective intelligence of an organization and its networks to devise new ideas and solutions for increased profitability and growth.
