Learning to Control Brain Activity Improves Visual Sensitivity

Training human volunteers to control their own brain activity in precise areas of the brain can enhance fundamental aspects of their visual sensitivity, according to a new study in the Journal of Neuroscience.

This non-invasive ‘neurofeedback’approach could one day be used to improve brain function in patients with abnormal patterns of activity, for example stroke patients. (more…)

Space Life

NASA funds astrobiology research by Delaware Biotechnology Institute scientist

Does life exist anywhere else in the universe? That’s the type of broad but poignant question NASA likes to ask, according to Chandran Sabanayagam, associate scientist in the Bioimaging Center at the Delaware Biotechnology Institute (DBI). And he would know, because he’s preparing to help answer it.

NASA will receive $100 billion from the federal government over the next five years to assure America is number one in space exploration, according to Astrobiology.com. As part of its push to seek new partnerships and broaden its vision, NASA is offering grants to people conducting transformational science. With this opportunity, Sabanayagam is merging his love of physics and biology. (more…)

Grand Canyon as Old as the Dinosaurs, Suggests New Study Led by CU-Boulder

An analysis of mineral grains from the bottom of the western Grand Canyon indicates it was largely carved out by about 70 million years ago — a time when dinosaurs were around and may have even peeked over the rim, says a study led by the University of Colorado Boulder. (more…)

Nanotechnology for drug delivery shows promise in treatment of pediatric leukemia

Nanotechnology developed by Delaware scientists could potentially deliver chemotherapy to children in a way that attacks cancer cells without harming healthy cells, greatly reducing side effects.

The work, conducted by researchers in the University of Delaware’s Department of Materials Science and Engineering and Nemours Center for Childhood Cancer Research, was published this month in the journal Molecular Pharmaceutics. (more…)

First Measurements Made of Key Brain Links

Until now, brain scientists have been almost completely in the dark about how most of the nonspecific thalamus interacts with the prefrontal cortex, a relationship believed to be key in such fundamental functions as maintaining consciousness and mental arousal. Brown University researchers performed a set of experiments, described in the Journal of Neuroscience, to explore and measure those circuits for the first time. (more…)

NASA Mars Rover Fully Analyzes First Soil Samples

PASADENA, Calif. – NASA’s Mars Curiosity rover has used its full array of instruments to analyze Martian soil for the first time, and found a complex chemistry within the Martian soil. Water and sulfur and chlorine-containing substances, among other ingredients, showed up in samples Curiosity’s arm delivered to an analytical laboratory inside the rover. (more…)

Harmful Protein-Coding Mutations in People arose Largely in the Past 5,000 to 10,000 Years

A study dating the age of more than 1 million single-letter variations in the human DNA code reveals that most of these mutations are of recent origin, evolutionarily speaking. These kinds of mutations change one nucleotide – an A, C, T or G – in the DNA sequence. Over 86 percent of the harmful protein-coding mutations of this type arose in humans just during the past 5,000 to 10,000 years. (more…)
