Engineers find better way to detect nanoparticles
An engineering team has made major strides recently in the study and manipulation of light. The team's most recent discovery of the sensing capability of microresonators could have impacts in the creation of biomedical devices, electronics and biohazard detection...
Aging is exacerbated by alterations of stem cell circadian rhythm
Two new studies refute the scientific dogma associating aging with the loss of stem cell circadian rhythm. The studies show that during aging, stem cells continue to show rhythmic activity but reprogram their circadian functions. The team also demonstrate that a...
San Salvador pupfish acquired genetic variation from island fish to eat new foods
Pupfish living in salty lakes on San Salvador Island were able to diversify into multiple species with different eating habits, in part, by interbreeding with pupfish from other islands in the Caribbean. read the full article
New methods for analyzing gene function
Scientists have developed new methods to produce and analyze genetic mosaics. In these mosaics, tissues contain various groups of cells with different known genotypes, permitting study of the differences that these genotypes generate in cell behavior. read the full...

First data transmission through terahertz multiplexer: 100 times faster than today’s best
Researchers have demonstrated the transmission of two separate video signals through a terahertz multiplexer at a data rate more than 100 times faster than today's fastest cellular data networks. read the full article
Arrival of modern humans in Southeast Asia questioned
Humans may have exited out of Africa and arrived in Southeast Asia 20,000 years earlier than previously thought, a new study suggests. Findings also suggest humans could have potentially made the crossing to Australia even earlier than the accepted 60,000 to 65,000...
