CSHL scientists discover a new way in which epigenetic information is inherited
Hereditary information flows from parents to offspring not just through DNA but also through the millions of proteins and other molecules that cling to it.   view more (2008-12-01)

Scientists developing food allergy treatment
A team of scientists from across Europe are embarking on new research to develop a treatment for food allergy.   view more (2008-12-01)

Drink brewed tea to avoid tooth erosion
Today, the average size soft drink is 20 ounces and contains 17 teaspoons of sugar. More startling is that some citric acids found in fruit drinks are more erosive than hydrochloric or sulfuric acid-which is also known as battery acid.   view more (2008-11-26)

Old flies can become young moms
Female flies can turn back the biological clock and extend their lifespan at the same time, University of Southern California biologists report.   view more (2008-11-25)

Bound by Attention: Bringing rats and humans together
When picking through a basket of fruit, it doesn't seem very difficult to recognize a green pear from a green apple. This is easy, thanks to "feature binding"- a process by which our brain combines all of the specific features of an object and gives us a complete and unified picture of it.   view more (2008-11-19)

Social interactions can alter gene expression in the brain, and vice versa
Our DNA determines a lot about who we are and how we play with others, but recent studies of social animals (birds and bees, among others) show that the interaction between genes and behavior is more of a two-way street than most of us realize.   view more (2008-11-07)

New hybrid plants could prompt more prodigious pepper production in Southwest
By themselves or as an ingredient in a variety of foods, including salsa, America's top-selling condiment, peppers have found a warm spot in the hearts and stomachs of U.S. consumers.   view more (2008-11-05)

Scientists probe Antarctic glaciers for clues to past and future sea level
Scientists from the U.S., U.K. and Australia have teamed up to explore two of the last uncharted regions of Earth, the Aurora and Wilkes Subglacial Basins, immense ice-buried lowlands in Antarctica with a combined area the size of Mexico.   view more (2008-10-28)

Making flies sick reveals new role for growth factors in immunity
A Salmonella infection is not a positive experience. However, by infecting the common laboratory fruit fly Drosophila melanogaster with a Salmonella strain known for causing humans intestinal grief, researchers in the School of Life Sciences at Arizona State University have shed light on some key... view more (2008-10-27)

Purple tomatoes: The richness of antioxidants against tumors
Researchers from the John Innes Centre in Norwich, Great Britain, in collaboration with other European centres participating to the FLORA project, have obtained genetically modified tomatoes rich in anthocyanins, a category of antioxidants belonging to the class of flavonoids.   view more (2008-10-27)

Nutrition advice best served with family in mind
Researchers at the University of Sheffield and Royal Holloway, University of London will argue today (21 October 2008) that the nation's diet is unlikely to improve significantly if healthy eating policies fail to take into account the diverse nature of contemporary family life.   view more (2008-10-22)

Novel genetic screens provide panoramic views of cellular systems
Despite the rise of systems biology, many geneticists continue to probe genes in isolation. They even use cutting-edge RNA interference (RNAi) technology to knock down one gene at a time. This approach often yields a narrow view of cellular systems.   view more (2008-10-17)

Researchers identify genetic switch critical for cell survival in hypoxia
Researchers at the University of California, San Diego School of Medicine have identified a critical metabolic "switch" in fruit flies that helps oxygen-deprived cells survive.   view more (2008-10-17)

Fructose Sets Table For Weight Gain Without Warning
Eating too much fructose can induce leptin resistance, a condition that can easily lead to becoming overweight when combined with a high-fat, high-calorie diet, according to a new study with rats.   view more (2008-10-16)

Herbicide-resistant grape could revitalize Midwest wine industry
An herbicide that is effective at killing broadleaf weeds in corn, but also annihilated most of the grapes in Illinois and other Midwestern states, may finally have a worthy contender. Researchers at the University of Illinois have developed a new grape called Improved Chancellor which is resistant... view more (2008-10-15)

Scientists trace molecular origin of proportional development
When it comes to embryo formation in the lowly fruit fly, a little molecular messiness actually leads to enhanced developmental precision, according to a study in the Oct. 14 Developmental Cell from Cincinnati Children's Hospital Medical Center.   view more (2008-10-14)

Pectin power
Scientists have found a new possible explanation for why people who eat more fruit and vegetables may gain protection against the spread of cancers.   view more (2008-10-13)

Biological alternatives to chemical pesticides
With increasing consumer pressure on both farmers and supermarkets to minimise the use of chemical pesticides in fruit and vegetables, a new study, funded by the Economic and Social Research Council (ESRC), looks at why there is currently little use of biological alternatives in the UK.   view more (2008-10-08)

Research shows Brazilian acai berry antioxidants absorbed by human body
A Brazilian palm berry sweeping the globe as a popular health food - though little research has been done on it - now may have its purported benefits better understood.   view more (2008-10-07)

Mental barriers hamper obese women's efforts to get exercise
For arachnophobes, it's difficult to kill a spider as it scurries across the floor. Those who are scared to fly might not ever set foot on a plane. While nothing physically stops people with these aversions, a mental barrier can keep them from the task at hand.   view more (2008-10-06)

Bee swarms follow high-speed 'streaker' bees to find a new nest
It's one of the hallmarks of spring: a swarm of bees on the move. But how a swarm locates a new nest site when less than 5% of the community know the way remains a mystery.   view more (2008-10-03)

Shift in bald eagle diet linked to sea otter decline
A newly published study has found that the decline of sea otters along Alaska's Aleutian Islands has forced a change in the diet of a terrestrial predator - the bald eagle. The study demonstrates the extraordinary complexity of marine ecosystems and how far-ranging the impacts can be when there is... view more (2008-10-03)

Short RNAs show a long history
MicroRNAs, the tiny molecules that fine-tune gene expression, were first discovered in 1993. But it turns out they've been around for a billion years.   view more (2008-10-02)

When cells go bad
When a cell's chromosomes lose their ends, the cell usually kills itself to stem the genetic damage. But University of Utah biologists discovered how those cells can evade suicide and start down the path to cancer.   view more (2008-10-01)

A plum assignment
Plums: they're sweet, juicy, and packed with beneficial antioxidants and dietary fiber. Although there are many varieties available to consumers, there are two main types of the small, purple fruit: Japanese plums and European plums.   view more (2008-09-30)
