Halloween is a holiday with lots of creepy wildlife associated with it, but are they really so creepy? From toads to bats to owls, the National Wildlife Federation shares the facts about these animals and what they are up to at this time of year, which might dispel a few myths. Bats - are they out for my blood?

The 2008 presidential campaign, as reflected in candidates' television spots, has been one of the most negative campaigns in history. A University of Missouri professor analyzed this year's candidates' television spots, including last night's 30-minute ad by Sen. Barack Obama and found that only one other campaign matched this level of negativity.
William Benoit, professor of communication in the College of Arts and Science, found that in television spots from 1952-2004, candidates averaged 40 percent attacks in their ad statements. In this year's race, the statements in Obama's ads were 68 percent negative compared to 62 percent for Sen. John McCain.

According to new research from the Monell Center, the degree of change in blood triglyceride levels following a fatty meal may indicate susceptibility to diet-induced obesity. The findings open doors to new methods of identifying people, including children, who are at risk for becoming obese. Triglycerides are a form of fat that is transported in the blood and stored in the body's fat tissues. They are found in foods and also are manufactured by the body. 

The largest such study ever published finds that while about 40 percent of women surveyed report having sexual problems only 12 percent indicate that those issues are a source of significant personal distress. The report led by a Massachusetts General Hospital (MGH) physician appears in the November issue of Obstetrics&Gynecology. 

You have a burning chest pain and a doctor looks at a squiggly-lined graph to determine the cause. That graph, an electrocardiogram (ECG or EKG), can help the doctor decide whether you're having a heart attack or an acid attack from last night's spaghetti. Correct interpretation may prompt life-saving, emergency measures; incorrect interpretation may delay care with life-threatening consequences. Currently, there is no uniform way to teach doctors in training how to interpret an ECG or assess their competence in the interpretation.

The 5,300 year old human mummy dubbed Öetzi (or ‘the Tyrolean Iceman’)  is highly unlikely to have modern day relatives, according to new research published today by a team of scientists from Italy and the UK. They have sequenced Öetzi’s entire mitochondrial DNA (mtDNA) genome, which is passed down through the maternal line, and found that he belonged to a genetic lineage that is either extremely rare or has died out.The research has generated the oldest complete Homo sapiens mtDNA genome to date, and overturns previous research conducted in 1994 on a small section of Öetzi’s mtDNA, which suggested that relatives of Öetzi may still exist in Europe.

Can't get enough of The Beatles?   Two days ago we disclosed that a mathematician using Fourier transform had unlocked the secret of the 'mystery' chord in "A Hard Day's Night" and now The Beatles are back again - in a video game.
Apple Corps, along with EMI Music, Harrisongs Ltd, and Sony/ATV Music Publishing, have agreed to present The Beatles music in an interactive video game format, to be published by MTV Games and developed by Harmonix.

Normal-weight women who carry out lots of vigorous exercise are approximately 30% less likely to develop breast cancer than those who don't exercise vigorously, according to a study of more than thirty thousand postmenopausal American women reported in Breast Cancer Research.  So a sedentary lifestyle can be a risk factor for the disease – even in women who are not overweight.

A "living fossil" tree species is helping a University of Michigan researcher understand how tropical forests responded to past climate change and how they may react to global warming in the future, according to research in the November issue of  Evolution.Symphonia globulifera is a widespread tropical tree with a history that goes back some 45 million years in Africa, said Christopher Dick, an assistant professor of ecology and evolutionary biology who is lead author on the paper. It is unusual among tropical trees in having a well-studied fossil record, partly because the oil industry uses its distinctive pollen fossils as a stratigraphic tool. 

Scientists have long been on the hunt for evidence of antimatter, matter's arch nemesis and a staple of science fiction in the last century, that might be left over from the very early Universe.  But the latest  results using data from NASA's Chandra X-ray Observatory and Compton Gamma Ray Observatory suggest the search is not going to get any easier.Antimatter would be made up of elementary particles, each of which has the same mass as their corresponding matter counterparts --protons, neutrons and electrons -- but the opposite charges and magnetic properties. When matter and antimatter particles collide, theory says they annihilate each other and produce energy according to Einstein's famous equation, E=mc2.

New research from the University of Bristol brings stem cell therapies for heart disease one step closer. The findings reveal that our bodies' ability to respond to an internal 'mayday' signal may hold the key to success for long-awaited regenerative medicine.   Dr Nicolle Kränkel and colleagues at the Bristol Heart Institute have discovered how our bodies initiate DIY rescue and repair mechanisms when blood supply is inadequate, for example in diabetic limbs or in the heart muscle during heart attack. Their findings also provide a practical step to advance progress in stem cell therapies.

The NASA/ESA Hubble Space Telescope is back in business with a snapshot of the fascinating galaxy pair Arp 147. The science operations were resumed on 25 October 2008, four weeks after a problem with the science data formatter took the spacecraft into safe mode.On Sunday 28 September 2008, the NASA/ESA Hubble Space Telescope automatically entered safe mode when errors were detected in the Control Unit/Science Data Formatter-Side A. This component is essential for the storage and transmission of data from the telescope's science instruments back to Earth. The component was reactivated on Thursday 23 October, and the Wide Field Planetary Camera-2 science observations resumed on Saturday 25 October.
