Newly described protein drives immune response, offers potential target for treatment Autoimmune diseases, which are estimated to affect more than 15 million people in the U.S., occur when the body responds to immune-system false alarms, and infection-fighting first responders are sent out to attack threats that aren’t there. Scientists have long understood how the false alarms get triggered, but the second step of dispatching the immune response has been a mystery. Now, scientists at Washington University School of Medicine in…
Not looks or money but rather life-long fidelity is what most people seek in an ideal mate, according to a Cornell University behavioral study that also confirmed the “likes-attract” theory: We tend to look for the same characteristics in others that we see in ourselves.
The study began when Cornell University students in an animal-behavior class conducted a scientific survey of 978 heterosexual residents of Ithaca, N.Y., ages 18-24. Hoping to learn whether likes attract, students asked the
The University of Bradford has conducted a study that reveals that mobile phone use can improve the short-term memory of men – but not women.
Dr Jim Smythe and Professor Brenda Costall of the University’’s School of Life Sciences carried out an experiment on both the long and short-term memory of people that were briefly exposed to electromagnetic fields (EMF) emitted from mobile telephones.
Thirty-three male and twenty-nine female students volunteered to be randomly assigne
The human brain combines motion and shape information to recognize faces and facial expressions, a new study suggests.
That new finding, part of an engineer’s quest to design computers that “see” faces the way humans do, provides more evidence concerning a controversy in cognitive psychology.
Were computers to become adept at recognizing faces and moods, they would be more user-friendly, said Aleix Martinez, assistant professor of electrical engineering at Ohio State University. T
Police should hand out more traffic tickets. While Robert Tibshirani, PhD, won’t win any popularity contests with that sentiment, the Stanford School of Medicine researcher and his colleagues at the University of Toronto report in a paper being published in the June 28 issue of The Lancet that vigilant traffic law enforcement may reduce fatal car crashes.
The team examined the records of drivers in Ontario, Canada, and found that receiving a traffic ticket reduces a driver’s risk of dying i
Biodiversity in urban/suburban yards correlates with household income
Biodiversity in urban and suburban yards directly correlates with household income, scientists have found.
Researchers at the National Science Foundation (NSF)-funded Central Arizona-Phoenix Long-Term Ecological Research (LTER) site found higher plant diversity in “upscale” neighborhoods. “The line flattens out, however, at about the $50,000 per year salary mark,” said scientist Charles Redman. “When inves
A team of scientists from the USA in collaboration with staff at the European Synchrotron Radiation Facility (Schotte et al) have managed to film a protein at work in unprecedented detail. The protein is the oxygen-storing molecule myoglobin, which plays a central role in the production of energy in muscles. The motion of the protein was recorded using ultra-short flashes of X-ray light from the synchrotron. The new insight in the functionality of myoglobin has led to a deeper understanding of the m
Policies like the London Plan, which are designed to shape the cities of the future, are based on outdated assumptions about the way people live and work, according to research funded by the Economic & Social Research Council.
“There is a great deal of talk about ‘joined-up thinking’’ about transport, housing and other policies,” says project leader Dr Helen Jarvis, “but in practice householders are having to fire-fight in a climate where planners and policymakers are not up to date.”
MGH imaging study finds differences in brain area responsible for vigilance
A key area in the brains of people who displayed an inhibited temperament as toddlers shows a greater response to new faces than does the same brain area in adults who were uninhibited early in life, according to a study by researchers from Massachusetts General Hospital (MGH). The imaging studies of the amygdala – a part of the brain that responds to events requiring extra vigilance – appear in the June 20 i
New study presented today at Image-guided Therapies media briefing
Radiofrequency ablation (RFA) combined with chemotherapy is currently being used to treat malignant liver tumors at a Boston hospital on the basis of results from a new study appearing in the July issue of the journal Radiology. The minimally invasive, outpatient procedure is performed on primary liver cancer or colon cancer tumors that have spread to the liver of patients at Beth Israel Deaconess Medical Center.
People facing economic hard times are more likely to vote when they believe government is at fault
Contrary to previous research indicating that people who are enduring financial hardship are less likely to vote, a study at Rice University suggests this is not always the case.
“Data from the American National Election Studies demonstrate that those facing economic adversity are more likely to vote when they blame the government for economic outcomes,” said Kevin Arceneaux, a poli
Biodegradable scaffold significantly increases the rate of bone healing
University of Toronto scientists have developed a biodegradable scaffold, similar in structure to a dish sponge, that significantly speeds the rate of bone healing.
The material, developed by an interdisciplinary team with expertise in engineering, biology, chemistry and dentistry, provides a building scaffold for bone growth. The scaffold, which eventually dissolves, increases healing rates and offers
Three decades of research on men’s sexual arousal show patterns that clearly track sexual orientation — gay men overwhelmingly become sexually aroused by images of men and heterosexual men by images of women. In other words, men’s sexual arousal patterns seem obvious.
But a new Northwestern University study boosts the relatively limited research on women’s sexuality with a surprisingly different finding regarding women’s sexual arousal.
In contrast to men, both heterosexual and
UC Riverside Sociologists Say Men Likely to Have Better Behaved Children and Wives Who Find Them More Sexually Attractive
Dads deserve a day off on Sunday, June 15. But on every other day they should know that when they do housework with their children, their kids turn out to be better adjusted and more socially aware. And, their wives find them more attractive.
Sociologists Scott Coltrane and Michele Adams of the University of California, Riverside, looked at national surv
The German health and fitness market is the second largest in Europe and it ’s still growing – but what does the future hold?
There are many different facets of the German health and fitness market. It has four different trade associations and generated total sales of just € 3.16bn in 2002 (Source: DSSV), which is less than Porsche AG’s annual turnover.
Until now, there hasn’t been any accurate data of the total size of this market. However, since 1999, Deloitte & Touche
National Insitute of Standards and Technology (NIST) scientists are taking their knowledge of mechanical tensile strength tests in metals and composites and applying it to medical research problems. Doctors long have known that babies born with congenital heart defects at higher altitudes have an increased risk of developing complications, such as pulmonary hypertension. Could there be some way to trick the arterial walls so that they wouldn’t stiffen under increased blood pressure?

In experiments conducted at the University of California, Berkeley, researchers have found a way to tap into the telltale electrical signals that mark cell death, opening the door to the creation of a “canary on a chip” that can be used to sound the alarm of a biochemical attack or test drug toxicity on human tissue.
In a study appearing in the June 15 issue of Sensors and Actuators, researchers used a microchip to electrically determine cell viability by detecting changes in the electrica
