Penguins that died 44,000 years ago in Antarctica have provided extraordinary frozen DNA samples that challenge the accuracy of traditional genetic aging measurements, and suggest those approaches have been routinely underestimating the age of many specimens by 200 to 600 percent.

Ideal nanoparticle cancer therapies surf the bloodstream

Researchers are studying blood using computer models that simulate how the fluid and the cells it contains move around. One new study shows how components in blood line up to prepare for healing; another demonstrates the best shape to use for man-made nanoparticles that target cancers -- a surfboard.

Improving security with face recognition technology

A number of US states now use facial recognition technology when issuing drivers licenses. Similar methods are also used to grant access to buildings and to verify the identities of international travelers. Historically, obtaining accurate results with this type of technology has been a time intensive activity. Now, researchers have developed ways to make th […]

Runners: Train less and be faster

A new scientific study demonstrates that by reducing the volume of training by 25% and introducing speed endurance training, endurance trained runners can improve not only short-term but also long-term performance.

Self-cleaning silicone gel insect wings

Researchers are flying the idea that insect wings could act as a model for making self-cleaning, frictionless, and superhydrophobic materials.

Child psychology: tips on taming the 'boogie monster'

A study of about 50 4-, 5-, and 7-year-olds identified coping strategies by having children listen to short illustrated stories in which a child came into contact with something that looked like a real or an imaginary frightening creature. In situations in which a child's fear was caused by real creatures, the researchers found, children would rather do […]

Longevity tied to genes that preserve tips of chromosomes

Scientists have found a clear link between living to 100 and inheriting a hyperactive version of an enzyme that rebuilds telomeres -- the tip ends of chromosomes.

Teenage Obesity Linked To Increased Risk Of Multiple Sclerosis

Teenage women who are obese may be more than twice as likely to develop multiple sclerosis as adults compared to female teens who are not obese, according to a new study.

Lab Machine To Study Glacial Sliding Related To Rising Sea Levels Created

Researchers have created a glacier in a freezer that could help scientists understand how glaciers slide across their beds. That could help researchers predict how climate change accelerates glacier sliding and contributes to rising sea levels.

Genetic Changes Shown To Be Important Indicators For Disease Progression In Cervical Cancer Patients

Cervical cancer patients with specific changes in the cancer genome have a three- or fourfold increased risk of relapse after standard treatment compared to patients without these changes, according to a new study. The research suggests that specific genetic changes are crucial steps in the progression of the disease towards an aggressive and treatment-resis […]
