Extinct Sabertooth Cats Were Social, Found Strength In Numbers, Study Shows:
The sabertooth cat (Smilodon fatalis), one of the most iconic extinct mammal species, was likely to be a social animal, living and hunting like lions today, according to new scientific research. The species is famous for its extremely long canine teeth, which reached up to seven inches in length and extended below the lower jaw.
Sea Urchin Yields Key Secret Of Biomineralization:
The teeth and bones of mammals, the protective shells of mollusks, and the needle-sharp spines of sea urchins and other marine creatures are made-from-scratch wonders of nature.
Ancient Mummy, The Tyrolean Iceman, Has No Modern Children:
The 5,300 year old human mummy - dubbed Ãetzi or 'the Tyrolean Iceman' - is highly unlikely to have modern day relatives, according to new research.
A Pretty Face Can Make A Difference In Whom You Vote For:
First it was Hillary Clinton, and now Sarah Palin. Everyone is talking about the year the glass ceiling finally cracked, if not shattered, in U.S. politics.
According to new Northwestern University research, it is not at all surprising that everyone also is talking about the great looks of vice presidential hopeful Palin.
Whether or not you believe the McCain campaign's $150,000 expenditure for Palin's wardrobe and the much-talked-about salary of her makeup artist are over the top, the decision to play up the looks of the former beauty queen is a winning strategy.
Even in 2008, a perception of competence -- a strong predictor of whether people will vote for political candidates -- is not enough to give women the winning edge in political contests, according to the new Northwestern psychology study.
For both men and women, female political candidates needed to be seen as attractive as well as competent to get their votes.
Inland Ants Often Prefer Salt Over Sugar, Implying Salt May Be A Limitation On Their Activity:
Ants prefer salty snacks to sugary ones, at least in inland areas that tend to be salt-poor, according to a new study published this week in the journal Proceedings of the National Academy of Sciences.
Scientists Identify Machinery That Helps Make Memories:
A major puzzle for neurobiologists is how the brain can modify one microscopic connection, or synapse, at a time in a brain cell and not affect the thousands of other connections nearby. Plasticity, the ability of the brain to precisely rearrange the connections between its nerve cells, is the framework for learning and forming memories.
Grapes And Grape Extracts May Lower Cardiovascular Disease Risk, Review Article Suggests:
A growing body of research data suggests that consuming foods rich in polyphenols from grapes, including red wine, helps reduce the risk of heart disease, according to a review article in the November issue of Nutrition Research.
Once Improbable James Bond Villains Now Close To Real Thing, Spy Researcher Says:
Professor Richard J. Aldrich, Professor of International Security at University of Warwick, who has just been awarded a £447,000 grant from UK's Art and Humanities Research Council to examine 'Landscapes of Secrecy' says that the once improbable seeming villains in the Bond movies have become close to the real threats face faced by modern security services. -------------- "Remarkably, the Bond villains - including Dr No, Goldfinger and Blofeld - have always been post-Cold War figures. Bond's enemies are in fact very close the real enemies of the last two decades - part master criminal - part arms smuggler - part terrorist - part warlord. They are always the miscreants of globalization, they endanger not only the security of single country, but the safety of the whole world. Like our modern enemies, they thrive on the gaps between sovereign states and thrive on secrecy."
Soft Rubber Harness Enables Researchers To Study Leatherback Turtles In Captivity For Years:
UBC PhD candidate T. Todd Jones has pioneered a soft rubber harness and a recipe that enabled him to raise and study leatherback turtles in captivity for more than two years -- a feat only one other team of scientists have achieved.
Bumblebee Colonies Which Are Fast Learners Are Also Better Able To Fight Off Infection:
Bumblebee colonies which are fast learners are also better able to fight off infection, according to scientists from Queen Mary, University of London and the University of Leicester.
Critically Endangered Fruit Bat Make Dramatic Return From Brink Of Extinction:
A once critically endangered bat species, the 'Pemba flying fox', has made a dramatic return from the brink of extinction, according to new research. As recently as 1989, only a scant few individual fruit bats could be observed on the tropical island of Pemba, off Tanzania. Its numbers have since soared to an astounding 22,000 bats in less than 20 years, the new research finds.
