Scientists Make Time Disappear
2012-01-05 11:39:46

Physicists working with the support from the US government said on Wednesday they had devised a “time cloak” that can make time disappear, albeit briefly. The device manipulates the flow of light in such a way that an event cannot be seen for about 40 trillionths of a second -- or 40 picoseconds -- by speeding up and slowing down different parts of a light beam. The different parts of the light beam were then re-assembled, so that any observers could not detect what happened...

Researchers Create Healthier Cigarette

[ Watch the Video ] From a health care perspective, the best cigarette is no cigarette, but for the millions of people who try to quit smoking every year, researchers from Cornell University may have found a way to make cigarette smoking less toxic. Using natural antioxidant extracts in cigarette filters, the researchers were able to demonstrate that lycopene and grape seed extract drastically reduced the amount of cancer-causing free radicals passing through the filter. The research...

With the share of married adults at an all-time low in the United States, new research by demographers at Cornell University and the University of Central Oklahoma unveils clues why couples don't get married — they fear divorce. Among cohabitating couples, more than two-thirds of the study's respondents admitted to concerns about dealing with the social, legal, emotional and economic consequences of a possible divorce. The study, "The Specter of Divorce: Views from Working and...

Bee Behavior Mimics Brain Neuron Function
2011-12-09 07:40:14

A new study of bees has come to the conclusion that bee swarm communication works similarly to that of neurons in the human brain. The study, published in the December 9 issue of Science, found that bees use inhibitory “stop” signals to prohibit the scout bees from completing a waggle dance that helps bees learn the directions of competing sites for new hives. This behavior helps to ensure that the best homesite is found for the hive. Thomas Seeley, a biologist from Cornell...

Twitter Works Like A Global Mood Ring
2011-09-30 05:11:51

Sociologists at Cornell University have turned to Twitter to study the collective mood of Americans, finding that people tend to cheer up by breakfast time and gradually taper their sentiments by late afternoon, before rallying again near bedtime. The researchers used Twitter in conjunction with language monitoring software to detect the presence of positive words in 509 million tweets from 2.4 million users in 84 different nations over a two-year period. Not surprisingly, the study...

New Technique Uses Genomes To Determine Ancient Human Migrations
2011-09-22 05:18:56

  Researchers at Cornell University have developed new statistical methods based on the complete genome sequences of living humans to shed light on events at the dawn of human history. The scientists applied their methods to the genomes of individuals of East Asian, European, and western and southern African descent.  Although they analyzed just six genomes, the researchers made use of the fact that these genomes contain traces of genetic material from thousands of human...

New study by Rice and Cornell researchers shows sustained interest in daily deals among consumers Despite recent news reports questioning the long-term viability of daily deal companies, a new study from researchers at Rice University and Cornell University shows that the companies are more popular than ever among consumers. "The key finding is that there is no evidence of waning interest among consumers of daily deal promotions," said Rice University's Utpal Dholakia, co-author of...

  Five American universities participating in a program to digitize books are being sued by authors in the U.S., the U.K., Canada and Australia, claiming that they have obtained unauthorized scans of millions of copyright-protected manuscripts, various media outlets reported Tuesday. Telegraph reporter Nick Allen reports that the lawsuit, which was filed in Manhattan, claims that the University of Michigan, the University of Wisconsin, the University of California, Indiana...
