Poor prenatal nutrition permanently damages function of insulin-producing cells in the pancreas

...week, restricted to only half the amount. It had a dramatic effect. At birth, their babies weighed 23 percent less than the control group. After delivery, all babies nursed and all mothers ate a full diet. "By the time the babies were weaned, at three weeks, the low-birth-weight group had caught up with the ...

Antarctic ice shelf retreats happened before

...res are believed to be the primary cause of recent dramatic disintegration of ice shelves like Larsen B, the new study suggests that the ocean may play a more significant role in destroying them than previously thought. The University of Durham's, Dr Mike Bentley, one of the leaders of the project said, 'We ...

Another Look Finds Promising Proteomics Test is Not Biologically Plausible

Understanding these changes is key tounderstanding cancer progression as well as developing possibletherapies and prognost...

Gene therapy converts dead bone graft to new, living tissue

Gertzman, executive vice president for research and development at the Musculoskeletal Transplant Foundation. Other scientist...

Experiments provide proof of how traveling in groups protects insects

Few events involving animals are more dramatic than when they band together and head out on the march cross-country. Among examples are the many thousands of wildebeests and other hoofed mammals that form herds and migrate across the African plains. Countless millions of Mormon crickets and yo...

Introduced foxes transformed vegetation on Aleutian Islands from lush grasslands to tundra

...the indirect effects on the whole ecosystem are as dramatic as the direct effects on the seabirds. "Introduced species are a global phenomenon, and we tend to focus on the direct effects, such as the reduction or extinction of species that are consumed by an introduced predator. This study shows how the effe...

Scientists document complex genomic events leading to the birth of new genes

...heir attention to the gene that exhibited the most dramatic of these duplications: RanBP2. RanBP2 is the largest protein found at the nuclear pore complex, helping to regulate nucleic acid and protein traffic in and out of the nucleus. The corresponding gene is present in all sequenced animal genomes but not ...

New Breast Cancer Test Could Save Lives

...the ages of 35-55 in Europe, the test could have a dramatic effect on the number of deaths from this disease. The test, which utilises an innovative radar system, will enable women to be tested regularly without the fear of over-exposure to radiation, a problem with existing X-ray tests. Currently, in order ...

Falling ants glide back to trunk to avoid dangers of forest floor

...," Dudley said. "Their 180-degree turns are pretty dramatic in the absence of wings." The team found that, unlike flying squirrels that can glide horizontally for long distances, the ants fall at a relatively high velocity, around 4 meters per second (12 feet per second), and approach the tree at a steep ang...

That prediction, which is based on the dramatic rise in obesity, especially among young people and minorities, is from a special report appearing in the March 17 issue in the New England Journal of Medicine. The study determines that obesity currently reduces life expectancy by approximately four...

Molecule that usually protects infection-fighting cells may cause plaque deposits inside arteries
