High levels of nutrients used in farming and ranching activities fuel parasite infections that have caused highly publicized frog deformities in ponds and lakes across North America, according to a new study led by the University of Colorado at Boulder.
Paleontologist Aims to Preserve Mountain
(AP) -- The New York Attorney General has subpoenaed Facebook after the company did not respond to "many" complaints by investigators who were solicited for sex while posing as teenagers on the social-networking site.
Purdue receives $18M nanotechnology grant
(AP) -- The Robledo Mountains' reputation as one of the world's most important landscapes of pre-dinosaur fossil trackways likely will be enhanced by another discovery - petrified wood slowly emerging from the desert floor.
Research team says extraterrestrial impact to blame for Ice Age extinctions
Purdue University has received an $18.2 million grant to support U.S. National Nanotechnology Initiative computer simulations.
Study: Acupuncture Works for Back Pain
What caused the extinction of mammoths and the decline of Stone Age people about 13,000 years ago remains hotly debated. Overhunting by Paleoindians, climate change and disease lead the list of probable causes. But an idea once considered a little out there is now hitting closer to home.
Study: Money Can Prod One to Lose Weight
(AP) -- Fake acupuncture works nearly as well as the real thing for low back pain, and either kind performs much better than usual care, German researchers have found.
What gives us sunburn protects crayfish against bacteria
(AP) -- People will lose weight for money, even a little money, suggests a study that offers another option for employers looking for ways to cut health care costs.
'Healthy' restaurants help make us fat, says a newl study
The production of melanin gives us sunburns, but it also helps invertebrate animals to encapsulate attacking fungi and parasites. Uppsala University researchers, in collaboration with Korean and Thai colleagues, can now show that melanin also protects against bacterial infections, at least in crayfish. The study is published in the latest Net edition of Journal of Biological Chemistry.
A search for biomarkers for early detection of colorectal cancer
If you're like most, you eat worst at healthy restaurants. The "health halos" of healthy restaurants often prompt consumers to treat themselves to higher-calorie side dishes, drinks or desserts than when they eat at fast-food restaurants that make no health claims, according to a series of new Cornell studies.
Collaboration shines possible light on objects 'weirder than black holes'
Researchers at the Zhejiang University, Hangzhou have discovered that mimecan and Thioredoxin Domain-Containing Protein 5 (TXNDC5) were differentially expressed in colorectal adenoma. The research article describing this work entitled Differential Expression of Mimecan and Thioredoxin Domain-Containing Protein 5 in Colorectal Adenoma and Cancer: A Proteomic Study will be featured in the...
New paper examines dams' effects on California salmon
Researchers from Duke University and the University of Cambridge think there is a way to determine whether some black holes are not actually black.
New Xerox Products Promise Deep Cuts
Spring-run Chinook salmon and other fish in the rivers of California`s Central Valley could be harmed by more water-storage dams, according to researchers at Duke University and the National Oceanic and Atmospheric Administration.
Research shows how genetic mutation causes epilepsy in infants
(AP) -- Xerox Corp. introduced color printers and ink products Monday that it said will cut the price of color copying by two-thirds, sweeping away a major hurdle for customers seeking to enter the profitable and growing color market.
Spaceflight shown to alter ability of bacteria to cause disease
New research from the Howard Florey Institute in Melbourne has shown why mutation in a single gene can cause epilepsy in infants.
Fluid theory confirmed by Foton spacecraft
Space flight has been shown to have a profound impact on human physiology as the body adapts to zero gravity environments. Now, a new study led by researchers from the Biodesign Institute at Arizona State University has shown that the tiniest passengers flown in spacemicrobescan be equally affected by space flight, making them more infectious pathogens.
Genes identified which predict response to breast cancer treatment
In scientific research, there is great satisfaction when theoretical work is eventually supported by experimentation. Such was the case this week for a team of Italian and US scientists when they received preliminary confirmation of a 10-year-old theory from a fluid science experiment that is currently orbiting the Earth on the Foton-M3 spacecraft.
Motorola enables High Definition expansion with innovative MPEG-4 to MPEG-2 Receiver
Scientists in Aberdeen have identified two genes that identify which breast cancer cells are resistant and which respond to a common chemotherapy treatment.
New imaging technique allows doctors to 'see' molecular activity
Motorola, Inc. today announced a significant advance in video network delivery solutions with the introduction of the Motorola DSR-6000 series receivers, the first of a new generation of receiver-transcoders. The DSR-6000 series is the first step in allowing networks to use both MPEG-4 AVC and MPEG-2 compression technologies.
New study suggests cause of debilitating skin condition
A new technique that will enable doctors to see` things happening at the molecular level using standard imaging techniques has been developed by Oxford scientists. The technique has initially been directed towards multiple sclerosis, but long-term it has the potential to be used for a vast range of health problems. The findings are published by Nature Medicine on Monday 24 September.
Sizing cells up: Researchers pinpoint when a cell is ready to reproduce
New findings from researchers at Wake Forest University Baptist Medical Center and colleagues suggest why some people with kidney failure can develop a rare tightening and swelling of the skin and other organs, including the lungs and heart.
Victimization for sexual orientation increases suicidal behavior in college students
For more than 100 years, scientists have tried to figure out the cell size problem: How does a cell know when it is big enough to divide? In research conducted in budding yeast (Saccharomyces cerevisiae), scientists at Rockefeller University have now identified the cellular event that marks the moment when a cell knows it is big enough to commit to cell division and spawn genetic replicas of...
Rare albino ratfish has eerie, silvery sheen
The film and television series M*A*S*H* featured the song Suicide is Painless, but new research refutes that idea and indicates that being victimized because of sexual orientation is a chief risk factor for suicidal behavior among gay, lesbian and bisexual college students.
Cancer cells in blood can identify risk of recurrence in breast cancer
A ghostly, mutant ratfish caught off Whidbey Island in Washington state is the only completely albino fish ever seen by both the curator of the University of Washington's 7.2 million-specimen fish collection and a fish and wildlife biologist with more than 20 years of sampling fish in Puget Sound.
Discovery of widespread tumor growth gene holds promise for effective anti-cancer treatment
Cancer cells circulating in the blood, or circulating tumour cells (CTCs), are known to be associated with a bad prognosis in women with metastatic breast cancer. Now, for the first time, a group of scientists have shown that they can also detect CTCs before and after chemotherapy treatment and hence may be able to identify those patients likely to have a recurrence of their cancer after such...
Italian scientists will announce today (Monday September 24) that they have found a new and promising target for anti-tumour therapy in cancer. Professor Saverio Alberti, from the CESI, University of Chieti Foundation, Chieti, will tell the European Cancer Conference (ECCO 14) that he and his team have found a widespread mechanism for the stimulation of tumour growth in man, and that this is...
