New Research Shows Artificial Light at Night Stimulates Breast Cancer Growth in Laboratory Mice

...and cancer risk can be confirmed, it could have an immediate impact on the production and use of artificial lighting in this country,?said Richard Stevens, Ph.D., an epidemiologist with the University of Connecticut Health Center who has authored several papers on the subject. “This might include lighting with...

All placebos not created alike

...ear as more and more lab experiments are detecting immediate physiological responses to placebos. A new study takes placebo investigations out of the lab and into a clinical trial, showing a discernible placebo effect over time, according to an article in the Feb. 1 British Medical Journal. While researchers...

Gene variation increases SIDS risk in African Americans

...lls of interrupted breathing or apnea. One of the immediate consequences of apnea is a slight increase in acid levels inside oxygen-hungry muscle cells. When the researchers compared cells with the Y1103 mutation against normal cells in a slightly more acidic environment, the cells with the abnormal channels...

Legume compounds may help cancer treatment

...universities. "Through UniQuest, Meristomics had immediate access to substantial commercial expertise and is looking to build on its patent success by attracting further funding to progress the research," Mr Harris said. The anti-cancer molecules are produced by legumes during the early symbiotic relations...

Oops! Researchers publish new findings on the brain's response to costly mistakes

St. Jude projects 90 percent cure rate for ALL

... focus in ALL therapy toward reduction of both the immediate and long-term side effects of treatment. For example, a St. Jude team lead by Evans demonstrated that patients who lack the enzyme TPMT are more sensitive to thiopurine chemotherapy drugs and are more likely to suffer damage to the body's blood-produ...

Climate change drives widespread amphibian extinctions

...ng emergence of infectious diseases are a real and immediate threat to biodiversity and a growing challenge for humankind. The decline of amphibians in apparently pristine, protected habitats in Costa Rica and elsewhere has perplexed conservation biologists since 1990, when the problem was first recognized. A...

UF researchers develop ways to keep the bloom on the rose

... behavioral study shows that fresh flowers have an immediate impact on happiness and increase life satisfaction and enjoyment. "It's not enough to offer consumers a beautiful flower," Nell said. "It needs to come with an extended warranty to remain lovely for a reasonable period of time. Our research is provi...

Sea coral's trick helps scientists tag proteins

...to ultraviolet light irradiation, which results in immediate conversion from green to red fluorescence, but they are not sensitive to blue light," Konstantin Lukyanov said. So the researchers did not expect Dendra to be activated by low-toxic visible light. "It was very surprising for us to observe an efficie...

Why nerve cells work faster than the theory allows

...ing to the new model, other sodium channels in the immediate neighborhood ?the channels open "cooperatively" and not ?as according to Hodgkin-Huxley ?independently of each other and only dependent on the voltage across the membrane. To test this hypothesis, the scientists used a trick: If it would be possible ...

Discovery of new molecular tools for biosynthesis could lead to advances in use of pectin

...evels.) While not the breakthrough that will allow immediate manipulation of total pectin biosynthesis, it is, one of the researchers involved said, "the first word of the Rosetta Stone that will show us the blueprint for pectin biosynthesis." The project, led by Debra Mohnen of the UGA department of biochemi...

Powerful technique for multiplying adult stem cells may aid therapies

...apy is another area where these findings can be of immediate value, Lodish says. With gene therapy, a genetic defect is corrected by administering a healthy version of the gene into a patient. For example, a physician isolates hematopoietic stem cells from a patient, introduces a harmless virus into them tha...

Genetic study shows humans have pushed orangutans to the brink of extinction

Portable cocaine sensor developed at UC Santa Barbara

...ntroduced to the market because of the need for an immediate check of the blood level of the drug in order to prevent death. Plaxco explained that new drugs may be made available when this sensor is applied to this medical use. To create the sensor, the researchers took a DNA molecule that converts from a flo...

Yale scientists decipher 'wiring pattern' of cell signaling networks

...ccording to Snyder, these findings in yeast are of immediate use for understanding both human development from the fertilized egg to full grown organism, and for drug discovery targeting human diseases. ...

Watch your step when the going gets rough

...the ground. In this case, you would make no use of immediate visual information during each step. Researchers monitored the accuracy with which subjects could step onto a target. In 50% of the attempts they blocked subjects' vision just at the point when they were lifting their foot off the ground. On the occ...

New technique puts brain-imaging research on its head

...aumatic brain injuries and concussions. "The most immediate application of our data will be in the development and validation of computer simulations of traumatic brain injury, which may ultimately reduce the need for direct experimentation." Bayly and Genin are collaborating with David Brody, MD, Ph.D., ins...

The brain is broadly wired for reproduction

...lab. The researchers published their studies in an immediate early publication on November 10, 2005, in the journal Cell. Related studies by HHMI investigator Catherine Dulac are published in the same issue. The scientists began their studies by focusing on tracing the neural pathways leading to and from neur...
