Researchers at Case Western Reserve University have discovered a link between a genetic pathway and autism, finding that mutations in this pathway are associated with both autism and other developmental disorders. The study suggests that the lack of specific genes may play a role in the development of autism.
A new study confirms that young teenagers think less about the future than adults, but it's not because they're impulsive. Research suggests that immaturity in brain systems governing sensation seeking, rather than self-control, contributes to this phenomenon.
A University of Iowa study found that smoking decreases a key protein in lung cells, leading to cell aging and damage. The team suggests targeting Werner's syndrome protein for developing treatments for smoking-related diseases like emphysema.
A study published in Science shows that when the apple maggot shifted hosts from hawthorn to European apples, it triggered a cascade of evolutionary changes in a parasitic wasp. The research reveals the process of speciation in action and sheds light on biodiversity's role in creating new species.
The NOAA-N Prime spacecraft has been launched into space, improving weather forecasting and monitoring environmental events around the world. The satellite will collect vital data on the Earth's surface and atmosphere, supporting NOAA's weather forecasts and providing critical inputs for search and rescue operations.
Researchers used electronic medical records to evaluate drug therapies, finding results comparable to randomized clinical trials in nine out of 17 outcomes. The study suggests enormous amounts of information within EMR databases can expand healthcare knowledge.
Michigan State University's NSF-funded Faculty Institutes for Reforming Science Teaching will train 200 postdoctoral researchers to teach scientifically. The program aims to equip future college professors with skills for teaching science effectively, using inquiry-based learning and promoting scientific literacy.
Researchers at NIST and Brookhaven National Laboratory have defined the structure of a metabolic switch found inside most types of bacteria, revealing how a key protein regulates genes involved in bacterial survival. The discovery could lead to new methods for preventing tuberculosis and other pathogenic diseases.
The FAME study found that stents placed using fractional flow reserve (FFR) had a 28% lower incidence of major adverse cardiac events compared to conventional angiography. This technique can distinguish between hemodynamically relevant and irrelevant stenoses, allowing for more targeted interventions.
The ALMA Observatory has accepted its first North American antenna, marking a significant milestone in the project. The 12-meter-diameter antenna was delivered by General Dynamics SATCOM Technologies and will enable astronomers to probe phenomena beyond the reach of visible-light telescopes with unprecedented sharpness.
A new study by Wake Forest University researchers found that teen programs most effectively promote responsibility when they assign difficult tasks, provide ownership, and hold teens accountable for their work. The study surveyed over 100 high schoolers participating in various summer and after-school programs.
A new study found that children comprehend the link between feelings and performance, but only for negative emotions. Children of all ages understood how emotional states impact school performance, while younger children struggled to grasp the connection between positive emotions and improved performance.
Scientists at the University of Nottingham and the University of California, Berkeley have provided evidence for a new kind of sudden transition between liquid and solid glass. This transformation occurs when molecules are viewed in both space and time, guiding towards methods for producing stronger and longer-lasting glass.
Research reveals that epigenetic regulation of 13 microRNAs is associated with higher mortality in patients with acute lymphoblastic leukemia. The study identifies these microRNAs as potential targets for new therapeutic options, offering hope for improved treatment outcomes.
A five-year Canadian study led by Dr. Cécile Tremblay aims to develop new strategies to fight AIDS in individuals who naturally control their HIV infection progression. The study will analyze factors predicting favourable outcomes and identify drivers of HIV diversity.
A new study shows that losing weight is the most effective way to reduce obstructive sleep apnea (OSA) symptoms and associated disorders. The study found that weight loss of more than 20 pounds resulted in markedly lower OSA symptoms and improvements in co-morbidities such as hypertension, high cholesterol, and diabetes.
Scientists at Scripps Research Institute have found that anti-oxidants in the diet can help preserve function by adding them to their diet. They also developed a novel gene therapy technique to offer an alternative option for arresting vision loss from eye diseases.
The Ovarian Cancer Research Fund (OCRF) and the Gynecologic Cancer Foundation (GCF) have jointly funded a new study on ovarian cancer symptoms, aiming to develop a systematic screening process. Dr. Barbara Goff will lead the three-year study, which seeks to create a symptom index for early detection.
A new study published in Child Development finds that preschoolers spend most of their day inactive, with 89% of physical activity characterized as sedentary. When balls and open spaces are made available, children become more likely to be active.
The new guideline provides recommendations for clinicians on how to safely prescribe potent opioid pain medications for patients with chronic non-cancer pain. Key findings include the importance of careful patient selection, monitoring, and ongoing assessment to minimize risks of abuse and addiction.
Physicians should avoid routine scans for low-back pain unless a significant underlying condition is identified. Regular use of radiography, MRI or CT scans does not improve patient outcomes and may increase medical costs.
Researchers at Case Western Reserve University discovered a nanotechnology-based technique to block damaging gas transport through polymers, making them stronger and more efficient. This breakthrough has potential applications in food and medicine packaging, as well as electronic equipment protection.
Complete Genomics successfully sequenced a Caucasian HapMap sample, generating 91x average read coverage of the genome in a matter of days. The company's system delivered unprecedented throughput, producing 254 Gigabases (Gb) of mapped data, and demonstrated an average run rate of over 70 billion mapped bases per run.
Researchers highlight potential security concerns for remote intelligent drug delivery systems, which could compromise patient safety. The team proposes implementing robust security mechanisms to mitigate hacking risks.
A study by researchers at the University of Rochester and others found that teenagers feel relatively obligated to help their parents, even when requests clash with personal desires. Parents tend to think it's more acceptable for teens to say no in such situations, suggesting a balance between family needs and individual preferences.
