The DEIMOS instrument will multiply the power of current Keck spectroscopy by a factor of seven, enabling observations of distant galaxies and shedding light on the formation and evolution of galaxies. With its massive detector and advanced optics, DEIMOS will create the most comprehensive map of the distant universe ever attempted.
Scientists at Max-Planck-Institute for Molecular Physiology develop a new concept for more efficient search of drug candidates. By employing biologically relevant natural products as starting point, the 'domain concept' aims to increase hit rate in compound libraries.
Researchers at Brown University have identified a new photoreceptor cell in the eye that turns light energy into brain signals, governing the body's 24-hour clock and helping people adjust to jet lag. This discovery expands our understanding of visual systems, suggesting a parallel system to the well-known rods and cones.
A study of 741 police officers found that those who experienced intense fear, horror, or helplessness during traumatic incidents had a higher risk of developing PTSD symptoms. Insomnia was also prevalent among the officers, with nearly half suffering from sleep disturbances typical of insomnia clinics.
Johns Hopkins researchers have identified a protein called stat3-beta that regulates genes involved in systemic inflammation. In mice engineered to lack this protein, researchers found fatal kidney failure due to uncontrolled inflammation, highlighting the potential of stat3-beta as a therapeutic target for human inflammatory diseases.
A study suggests that kinking in the iliac arteries is a common cause of blood flow restriction in endurance athletes, particularly cyclists and speed skaters. Surgical release of these kinks can improve performance and enable athletes to return to competition, with 87% successfully returning to their desired level.
A study using virtual blue jays as predators found that they drove the evolution of diverse wing markings in a population of virtual moths. The research, funded by the NSF, used a genetic algorithm to favor moths with more cryptic markings and found evidence of increased diversity after 100 generations.
Researchers have developed a way to fabricate superlattice nanowires, which can incorporate transistor junctions, light-emitting diodes, and lasers within a single wire. This breakthrough could lead to the creation of ultra-small electronic devices that are equal to or better than current hand-size electronics.
Researchers propose that the continents emerged suddenly over 200 million years ago, coinciding with the formation of supercontinent Rodinia. This theory suggests that changes in plate tectonics may have triggered evolutionary activity and influenced life's evolution.
D'Andrade's research focuses on cognitive anthropology, quantitative methods, and American culture, with a focus on insightful interpretations of historical trends shaping the future goals of anthropology. He is one of 14 individuals honored by the NAS this year.
Narcolepsy is a lifelong problem characterized by sudden sleep episodes and muscle paralysis triggered by strong emotions. A new study aims to understand the role of hypocretin cells in controlling sleep and arousal, with potential breakthroughs for future treatments.
The Coordinated Stroke Strategy led to a dramatic increase in stroke treatment rates, from 3.5 patients per month to an average of six patients per month. Intracerebral hemorrhage hospitalization rates varied by gender and geography, with higher rates among men and in the southern United States.
Chemists observed significant improvement in catalyst performance when changing support material, leading to up to ten-fold increase in efficiency. The researchers created nearly uniform nanoclusters of iridium atoms and found that the catalytic clusters and support were chemically bonded.
A study analyzing stable isotopes in feathers reveals that black-throated blue warblers segregate according to their summer breeding locations in North America, linking them to specific Caribbean wintering grounds. This research provides crucial insights for developing effective conservation initiatives for Neotropical migrants.
A new study finds that the updated birth control pills pose a significant stroke risk for women. The risk is similar to that of first-generation pills and higher than non-users.
The Choice Plus plan, a direct contracting health plan, contains costs and maintains quality of care. The study found that hospital care costs dropped, while ambulatory care rose slightly.
Researchers mapped the neural circuitry of a light-sensing system that governs the body's internal clock and regulates sleep-wake cycles, discoveries that could lead to new treatments for jet lag and depression. The study identified melanopsin as a key player in this system.
A new computer-based algorithm identifies a distinct proteomic pattern that distinguishes malignant from benign tumours within the ovary with 100% sensitivity and 95% specificity. This technique may help screen for ovarian cancer in high-risk and general populations.
Researchers create protein nanoarrays with features over 1,000 times smaller than conventional arrays, enabling more accurate and efficient detection of biomolecules. The technology, developed by Northwestern University, holds promise for applications in disease screening and biorecognition.
Researchers believe that bionic technologies can be adapted for restoring some degree of lost function, with progress continuing at its present pace. The development of wireless implants and miniaturized components will bring processing closer to the body, enabling more complex actions like walking.
Researchers found that dedicated stroke teams can improve treatment with tissue plasminogen activator (tPA) without increasing hospital costs. The use of tPA increased by 2.1 times in the year with a specialized team compared to the year without one.
