A University of Pittsburgh study found that prior concussions may lower the threshold for subsequent concussion injury and increase symptom severity in seemingly mild subsequent concussions. The research, which compared 60 athletes with no prior concussion history to 28 athletes with three or more concussions, showed a significant incr...
Researchers from the Pittsburgh Development Center are conducting clinical and pre-clinical studies to investigate genetic components of recurrent miscarriage, normal and abnormal pregnancy, and tobacco smoke exposure's impact on fetal growth. The team aims to track development at the cellular level using non-invasive imaging scans.
Duke researchers have made significant progress in synthesizing uniform 'buckytubes' using a new technique, which could lead to the development of smaller electronic circuitry and more precise control over their electronic properties. The achievement marks an important step towards realizing the full potential of carbon nanotubes.
Scientists using Whipple Observatory gamma-ray telescope discover energetic gamma-ray flares from active galaxies, revealing relativistic jets and compact emission regions. The study also holds promise to reveal nature of 'dark matter' and 'dark energy', which dominate universe's mass budget.
A new strategy in cancer treatment involves using genetic information to guide drug delivery, allowing for more targeted and efficient treatments. The approach uses nucleic acid-triggered catalytic drug release, recognizing and responding to unique cancerous sequences to deliver potent anticancer drugs.
A new online library, Digital Library for Earth System Education (DLESE), provides deaf students with interactive and visual resources that cater to their unique needs. The library offers reliable and up-to-date information, reducing the learning gap between deaf and hearing students.
The University of Wisconsin will lead a research network to develop and test immune-based treatments for asthma in inner-city children, building on successful NCICAS interventions that have reduced asthma severity.
The hypothesis proposes categorizing diverse symptoms according to unconscious aggressive conflict, rather than conscious superficial descriptors. This approach could reveal common neuroanatomical correlates among seemingly disparate symptoms.
A new excavation at Teotihuacan's Pyramid of the Moon reveals a distinctive Mayan-style burial with jade artifacts, suggesting a direct connection between Teotihuacan rulers and the Maya royal families. The discovery sheds new light on the government of Teotihuacan and its potential influence on Mayan politics.
The AIDS and Cancer Specimen Bank at UCSF is expanding its operations with new technologies and a central coordinating office. The bank now serves over one million specimens from around the world, including China, Thailand, and South America.
Boaz's discovery and commercialization of the BoPhoz¼tm chiral ligands have reached a total market value of over $100 billion, driving researchers to develop new catalysts for synthesizing one-handed forms. These ligands offer pharmaceutical scientists a new path to produce active ingredients quickly and at lower cost.
Researchers have developed a new vaccine that amplifies the production of beneficial antibodies to combat IP-10, a protein responsible for autoimmune disease progression. The vaccine rapidly suppressed experimentally induced rheumatoid arthritis and MS, offering potential relief for millions.
New research at the University of Illinois Chicago found that chromatin, not proteins, provides structural support for chromosomes during cell division. The study used a novel methodology involving DNA digestion and glass tube pipettes, which may help unlock the puzzle of how cells divide.
Research published in PNAS found that caloric restriction can confer significant health benefits for the heart and extend its working life by exerting influence on the genetic program governing heart cells. In middle-aged mice, cutting calories prevented age-related genetic changes that damage heart cells and promote inflammation.
A Rutgers University study shows that Prozac treatment preserves female learning ability even under stress. Chronic Prozac treatment was found to be effective in protecting females from the negative effects of stressful experiences on learning. The researchers also found that males and females respond differently to stressful experiences.
The Stardust spacecraft is using a flyby of asteroid Annefrank to prepare for its primary mission to capture particles from Wild 2. The asteroid's small size and distance from the spacecraft mean images won't be detailed, but it provides a crucial test for the spacecraft's systems.
A comprehensive periodontal examination can save lives by detecting undiagnosed protein S deficiency, a condition that causes thrombotic disorders and increases the risk of strokes and heart attacks. Early diagnosis is key to successful treatment outcomes and improved survival rates for patients with this condition.
The new sonar system, Advanced Sonar (SAS), offers four times the range and 36 times the resolution of traditional side-looking sonar. The CTTO facilitated a rapid transition by brokering a Memorandum of Agreement to incorporate SAS into the Mine Reconnaissance System.
A new study suggests that future extreme rain events could cause significant crop losses and damages, particularly in the US Corn Belt. The researchers used a modified crop model to simulate the effects of excess soil moisture on corn crops, finding potential damages up to $3 billion per year by the 2030s.
Researchers develop waveform templates to analyze gravity wave signals, enabling detection of neutron star collapses and black hole collisions. Gravity waves offer a window to the universe carrying different information than electromagnetic waves.
Morales-Martinez is recognized for her efforts to encourage economically disadvantaged high school students to pursue careers in chemistry through the Project SEED program. Her dedication to mentoring and promoting diversity has led to numerous awards, including the University Distinguished Service Medallion.
A Texas Agricultural Experiment Station study found that early planting, even in September, can give slash pine trees a growing head start towards better survivability. Container-grown trees showed more than 90% survival after the first year, compared to 60% for bare-root trees.
Researchers successfully transmitted haptic (touch) feedback across the Atlantic, enabling collaborative tasks like lifting a virtual box. The demonstration uses a robotic arm to simulate touch, allowing users to feel each other's manipulations in real-time.
Researchers at Cedars-Sinai Medical Center found that pituitary tumor cells express abundant PPAR-gamma, a protein receptor linked to growth and metabolism. Treatment with common diabetes drug rosiglitazone effectively shrunk tumors and reduced hormone production in mice with Cushing's syndrome.
A national effort is underway to study traumatic injury and develop evidence-based treatments. The project will compile extensive databases and standardize care procedures to help physicians choose the best treatment for each patient.
Researchers found that beta blockers significantly reduced overall death rates by 16-34% in two years, regardless of inducible tachycardia presence. However, the drugs did not reduce arrhythmic death or cardiac arrest, but showed a trend towards fewer events with combined antiarrhythmic and beta blocker therapy.
A new nanoparticle coating developed by researchers at Washington University in St. Louis mimics the natural properties of dolphin skin to prevent biofouling on ship hulls. The coating's complex surface features make it difficult for marine organisms to attach, reducing friction and drag.
A team of UCSD researchers found that regular outbursts of ultraviolet radiation from massive stars may play a significant role in stirring up galaxies. The simulation study suggests that this radiation acts as an important regulation mechanism, inhibiting further star formation and regulating the galactic perturbations.
