A world-first: birth of a white rhino after artificial insemination with frozen sperm.
The rhino baby, a male, was born at 4:57am in the Budapest Zoo on the 22nd of October 2008. In June 2007, scientists from the Leibniz Institute for Zoo and Wildlife Research in Berlin artificially inseminated his mother, the rhino cow Lulu, with frozen bull semen. The rhino baby weighed 45 kilos. It is in good health and was accepted by his mom. The birth is “an important success for species conservation and preservation of biodiversity”, says Dr. Robert Hermes, one of the IZW-scientists performing the insemination.
Based on past elections and economic factors, two professors at the University of Oregon predict that Senator Barack Obama will win the presidential election by a 52 to 48 margin.
In the paper "A Disaggregate Approach to Economic Models of Voting in U.S. Presidential Elections: Forecasts of the 2008 Election," published in the Economics Bulletin, economic professors Stephen Haynes and Joe Stone's research shows that lowest-income states prefer McCain by 55.4 percent to 44.6 percent. Middle income states are almost evenly split between the two candidates and highest-income states prefer Obama by 53.3 percent to 46.65 percent.
Haynes and Stone note in their research that the 52 to 48 margin in favor of Obama falls within the four-point range of statistical error.
If Barack Obama is elected president on Nov. 4, and current polling suggests that is the case, he will come into office with something few presidents get and all envy: both houses of Congress controlled by his own party. With Speaker Nancy Pelosi at the helm in the House, and Majority Leader Harry Reid presiding over what may be a filibuster-proof majority in the Senate, Obama, Pelosi and Reid will be able to fundamentally change the size, nature and scope of government.
When I was an undergraduate, I had to read Bram Stoker's
Dracula for a class called, "Myths of the World." The novel is composed of first hand accounts, diary entries, letters and newspaper clippings to add validity to the story, so as you're reading it, you begin to think--it's real. There I was one night, in my San Francisco apartment, huddled in my bedroom with all the lights on reading:
When the Count saw my face, his eyes blazed with a sort of demonic fury, and he suddenly made a grab at my throat. I drew away, and his hand touched the string of beads which held the crucifix. It made an instant change in him, for the fury passed so quickly that I could hardly believe that it was ever there. - Bram Stoker's Dracula
Newt Gingrich, John Kerry, and someone named Billy Beane (I have no clue who he is) argue that medicine is
not yet sufficiently data driven.:
In the past decade, baseball has experienced a data-driven information revolution. Numbers-crunchers now routinely use statistics to put better teams on the field for less money. Our overpriced, underperforming health care system needs a similar revolution...
Remarkably, a doctor today can get more data on the starting third baseman on his fantasy baseball team than on the effectiveness of life-and-death medical procedures. Studies have shown that most health care is not based on clinical studies of what works best and what does not — be it a test, treatment, drug or technology. Instead, most care is based on informed opinion, personal observation or tradition.
For the second time this year, The University of Western Ontario Meteor Group has captured incredibly rare video footage of a meteor falling to Earth. The team of astronomers suspects the fireball dropped meteorites in a region north of Guelph, Ontario, Canada, that may total as much as a few hundred grams in mass.
The Physics and Astronomy Department at Western has a network of all-sky cameras in southern Ontario that scan the sky monitoring for meteors.
On Wednesday, October 15 at 5:28 a.m., all seven cameras of Western's Southern Ontario Meteor Network recorded a bright, slow fireball in the predawn sky.
Does your boss feel like an environmentally aware entrepreneur? If so, it might be worth mentioning that business travel, conferences and meetings have an effect on the environment. Virtual participation is possible but computers, networks and the entire data infastructure consume massive amounts of power as well.
What is needed is a way to quantify meetings in terms of energy use. At a recent “Informatics Day at the Technopark Zurich" , a Microsoft booth allowed visitors were able to test how much CO2 they would save, if any, if they replaced a “real” meeting with a videoconference. Using life cycle analysis methods and the «ecoinvent» database, Empa researchers produced comparative data showing what environmental effects were created, and where.
Yesterday, the Zefiro 9-A motor successfully completed its first firing test at the Salto di Quirra Inter-force Test Range in Sardinia (Italy). This was the penultimate firing test for the engine prior to the Vega launcher’s qualification flight, scheduled to take place by the end of 2009.
The Zefiro 9-A (Z9-A) solid-fuel rocket motor, which will power the Vega launch vehicle’s third stage, left the production facility of Avio, in Colleferro (Italy), at the end of September and was installed at the test site over the last three weeks.
Does ice-cream actually taste better when it is licked from a cone than when eaten from a spoon?
Massey food technology senior lecturer Kay McMath thinks so. Although she is not aware of any specific scientific evidence to prove it, she says “there are some physical and physiological reasons why there are likely to be differences in flavour”.
“Flavour in ice cream is only released when the fat content – which carries the flavour – is warmed in the mouth to at least body temperature,” she says.
“During licking, the tongue is coated with a thin layer of ice-cream which is more quickly warmed and the flavour is detected by the large surface area of the taste buds present on the tongue.”
Some animals live longer when raised on low-calorie diets but now researchers at Washington University School of Medicine in St. Louis say that they can extend the life spans of roundworms even when the worms are well fed — it just takes a chemical that blocks their sense of smell.
Three years ago, the researchers, led by Kerry Kornfeld, M.D., Ph.D., reported they found that a class of anticonvulsant medications made the roundworm Caenorhabditis elegans live longer. But until now, they didn't quite know what the drugs did to give the worms their longevity.
