Oddly shaped DNA can cause DNA breaks in mammalian cells

When otherwise normal DNA adopts an unusual shape called Z-DNA, it can lead to the kind of genetic instability associated with cancers such as leukemia and lymphoma, according to a study by researchers at The University of Texas M. D. Anderson Cancer Center.

Effects of cancer treatment among children of survivors

Can the high doses of chemotherapy and radiation that young cancer patients receive cause inherited health problems for their children? Vanderbilt-Ingram Cancer Center member, John Boice, Sc.D., and an international team of colleagues have just been awarded a $4 million grant from the National Cancer Institute to try to find out.

Lifetime calorie restraint to prevent obesity is the most powerful way to reduce age-related health problems

University of South Florida researcher Barbara Hansen, PhD, will likely never be invited to talk about weight loss on Oprah. Her message is mundanely common sense, not faddish - she doesn't drop phrases like "low carb," or "low fat," or "geared to your body type" or "put your body into fat-burning mode."

Researchers create animal model of any schizophrenic characteristics

Researchers have developed a mouse strain in which the abnormal activity of the dopamine machinery in a specific part of the brain causes cognitive and behavioral impairments mimicking those in human schizophrenics.

Mystery of evolutionary growth in hominid brain size

Forget the textbook story about tool use and language sparking the dramatic evolutionary growth of the human brain. Instead, imagine ancient hominid children chasing frogs. Not for fun, but for food.

Ernst Mayr's theory illustrated in genetic epidemiology studies

The late, famed evolutionary biologist Ernst Mayr's theory of genetic revolution , introduced in 1954, remains controversial to this day and has many detractors.

GeneDesign speeds design of artificial pieces of DNA

Johns Hopkins researchers have announced the development of a Web-based, automated computer program that they say greatly simplifies the time-consuming and error-prone process of manually designing artificial pieces of DNA.

Inactivating Rad9 protien could make cancer cells easier to kill with ionizing radiation

The researchers found that Rad9, previously considered a "watchman" that checks for DNA damage, is actually a "repairman" that fixes dangerous breaks in the DNA double helix. They found Rad9 is especially active in telomeres, the protective ends of chromosomes.

Farnesyltransferase inhibitor may improve progeria

UCLA researchers found that an experimental cancer drug improves the signs of progeria in a mouse model. Progeria is a rare genetic disease causing accelerated aging and cardiovascular disease in children. The new UCLA findings help to define a new strategy for treating children with progeria.

Major Alzheimer's discovery

A team from the Faculty of Medicine at Universiti Laval and the research centre at CHUQ (Centre hospitalier universitaire de Quibec) has discovered a natural defence mechanism that the body deploys to combat nerve cell degeneration observed in persons with Alzheimer's disease (AD).

Genome data may contain small but significant errors

Since the genome sequence of the bacterial pathogen Haemophilus influenzae was published in 1995, the genetic code of many other large, complex, medically, and commercially significant organisms including humans has also been elucidated

Science is bypassing poor people

Applying science and technology to build a Pluto-bound spacecraft that travels more than 10 times faster -- 47,000 miles per hour -- than a speeding bullet is a great achievement. But can we apply technology to feed the 800 million hungry people in the world whose plight isn't improving in a modern world?
