A study suggests that chronic sleep restriction can have lasting effects on neurobehavioral deficits, even with adequate recovery sleep. Researchers found that participants who experienced severe sleep restriction showed persistent impairments in attention and reaction times after a single night of extended sleep.
Researchers at Northwestern University have developed a new method called beam-pen lithography, which uses tiny beams of light to draw patterns on surfaces. This technology offers a means to rapidly and inexpensively make and prototype circuits, optoelectronics, and medical diagnostics.
Professor Varda Shoshan-Barmatz has developed a peptide that targets and kills cancer cells while sparing normal cells. The grant will be used to develop therapeutic peptides for B-CLL, one of the most common and incurable hematological malignancies.
Researchers found that short-snouted dog breeds have rotating brains up to 15 degrees, while the olfactory lobe has relocated, affecting smell perception. The study highlights unique plasticity in the canine genome due to human intervention through breeding.
A new study has found that male infants are easier to arouse from sleep than female infants at 2-4 weeks of age, but this difference resolves by 2-3 months. The study suggests that the increased risk of sudden infant death syndrome (SIDS) in males may not be due to differences in arousability.
The researchers created a library of micromolded, hexagonally spaced elastomeric micropost arrays to study the effects of substrate flexibility on stem cell development and adhesion. The system allowed them to modulate the rigidity and flexibility of the substrate surface without changing its adhesive properties.
Research suggests that both short and long sleep durations are independently associated with an increased risk of cardiovascular disease. Adults who sleep less than seven hours per day or more than nine hours per night have a higher risk of heart problems compared to those who get average sleep duration.
Researchers identify an ancient gene family regulating nerve excitability in the brain, which may contribute to epileptic seizures. Studies on mice suggest that activating this potassium channel can block seizures, opening up potential new drug targets with fewer side effects.
Researchers at Cornell University have discovered how protein Mec1 acts as a 'guardian of the genome' in yeast cells. The study shows that Mec1 monitors and repairs machinery responsible for replicating DNA, allowing it to restart and continue replicating.
Two studies found that US adults who used nutritional labels consumed healthier nutrients, with significant differences in calorie and fat intake. A pilot study also showed that point-of-purchase nutrition information influenced college students' purchasing behaviors, promoting the sale of healthful food items.
Stem cell differentiation is a crucial process that can be accelerated using a novel type of matrix, adjusting its stiffness without altering its chemical composition. By analyzing traction forces and cellular behavior, researchers predict stem cell differentiation as early as Day 1.
Researchers at UC San Diego School of Medicine identify microRNA miR-132 as the 'gas pedal' controlling uncontrolled blood vessel growth. They develop an anti-miR therapy to restore functionality to the 'brake,' halting disease progression in mouse models of cancer and retinal disorders.
Researchers at University of Rochester developed a unique light-controlled membrane that can block gas flow when ultraviolet light is applied and allow it to flow when purple light is used. This innovation has potential applications in controlled drug delivery and industrial processing tasks.
Scientists used genome mining to discover a novel antibiotic in Streptomyces coelicolor, effective against several bacterial strains. The approach also unlocks potential for discovering new antimicrobials and antitumor agents from other micro-organisms.
