But your children seem to ignore this firm ruling, and insist on having both cake and ice cream. Are they merely rebelling against a parental command? Perhaps.

Analyses of ancient DNA from prehistoric humans paint a picture of dramatic population change in Europe from 45,000 to 7,000 years ago, according to a new study led by Howard Hughes Medical Institute Investigator David Reich at Harvard Medical School.

When a team of researchers at NIST’s Physical Measurement Laboratory (PML) first tested a new kind of pressure sensor two years ago, initial results showed it was faster and had higher resolution than the traditional, centuries-old mercury-based method for measuring pressure. The novel device, called the Fixed Length Optical Cavity (FLOC), works by detecting subtle changes in the frequency of light passing through a nitrogen gas-filled...

Researchers have demonstrated proof of concept for a novel low-energy nuclear reaction imaging technique designed to detect the presence of “special nuclear materials” – weapons-grade uranium and plutonium – in cargo containers arriving at U.S. ports. The method relies on a combination of neutrons and high-energy photons to detect shielded radioactive materials inside the containers.

UT Southwestern Medical Center plastic surgeons have developed a new breast reconstruction technique that combines advantages of two different types of microsurgical procedures using abdominal and other tissue to reconstruct the breast after a mastectomy.
