Researchers found that increased Labrador water transport due to Gulf Stream movement actually decreases primary productivity, contrary to expected outcomes. This phenomenon may be linked to nutrient supply and influence large-scale climatic effects on the carbon cycle.
Duke University Medical Center biochemists have successfully engineered a protein that can detect nerve agents like soman and sarin. The proteins could be incorporated into detectors, resembling smoke detectors, to provide early warning and monitor levels.
Researchers at the University of Wisconsin-Madison have developed a groundbreaking gene therapy technique that safely delivers therapeutic DNA to muscle cells. The innovative approach, which uses a non-viral method to inject genes into limb veins, has exciting implications for treating muscle and blood vessel disorders.
A recent study has challenged the widely practiced surgical procedure of cervical cerclage to reduce premature birth. The research found that only a small decrease in premature births occurred among women who received the surgery, highlighting the limitations of this method in reducing the risk of early preterm delivery.
A study found a high level of agreement between brown bags and pharmacy records, with mismatches often caused by missing medications from the pharmacy records. The method is useful for monitoring medication adherence in low-income older adults, particularly those with worse health or certain medical conditions.
A study involving 509 active duty military personnel found that eyewitness memory is poor in highly intense and stressful situations, regardless of presentation method. Recognition was better during low-stress conditions, with some participants even confusing the gender of the interrogator or guard.
Researchers discovered a molecular marker, the HOXB13:IL17BR ratio, that accurately predicts the reoccurrence of tumors in breast cancer patients treated with tamoxifen. This finding suggests that HOXB13 may contribute to tumor invasion and metastasis.
A study by Canadian scientists found high levels of pollutant films on windows in lower Manhattan six weeks after the 9/11 attacks, revealing concentrations up to 10 times greater than normal background levels. The findings suggest that urban areas like New York City have high levels of toxic organic pollutants.
A $300,000 study will examine the demand and availability of veterinarians in food supply-related disciplines. The research aims to address student recruitment, retention, and training to serve society.
Astronomers from Johns Hopkins University confirm the Cygnus Loop is closer to Earth than previously thought, with a distance of 1,860 light years. The new findings were obtained using the Far Ultraviolet Spectroscopic Explorer (FUSE) satellite and provide an accurate starting point for understanding this important supernova remnant.
A Duke University study found that former smokers who quit for 15 years or more have no significant difference in healthy life remaining compared to non-smokers. Heavy smoking reduces years of healthy life by approximately two years for men and 1.66 years for women, highlighting the importance of quitting now.
A study found that 18% of early-onset Parkinson's disease patients have a single parkin gene mutation, raising questions about the clinical implications of this finding. The study's results challenge the long-held assumption that two mutations are required to develop Parkinson's disease.
The study found that higher doses of Concerta were associated with significantly greater symptom response and remission rates in children with ADHD, compared to immediate-release methylphenidate. Overall, 70% of subjects showed a clinically meaningful treatment response to Concerta.
Researchers from MGH and Arcturus found that the HOXB13/IL17BR gene expression ratio predicts tumor recurrence in estrogen-receptor-positive breast cancer patients receiving tamoxifen. The higher expression of HOXB13 and lower IL17BR levels indicate increased risk of recurrence.
Geologists found that the removal of carbon dioxide from the atmosphere by continents led to a cooling effect, resulting in the collapse of the early greenhouse. The recycling of carbon through volcanic activity eventually regenerated the greenhouse, leading to a warming of the planet.
Researchers found that tamoxifen-resistant breast cancers grow due to PKA-activated estrogen receptor modification. Identifying patients with activated PKA may lead to alternative treatments with aromatase inhibitors or fulvestrant.
A study reveals that only 0.3% of UK population receives government support, while 80,000 people wait for healthcare services. The author argues that myths surrounding asylum seekers are debunked by highlighting the real cause of long waiting lists: underinvestment in the National Health Service.
Women's lungs are more damaged by cigarette smoke, leading to a different treatment response and outcomes. Research funding is needed to understand the causes of this disparity in lung cancer incidence among women.
Researchers at University at Buffalo found that corals can take up new algal symbionts from their environments, increasing cell densities and demonstrating a mechanism for recovery from bleaching. This study provides evidence of coral resilience in the face of environmental change.
A study by the University of Pennsylvania School of Medicine found that most antidepressants, except citalopram, are ineffective on mice lacking norepinephrine. The researchers tested eight commonly prescribed antidepressant drugs and discovered a critical link between norepinephrine and desired behavioral effects.
During next week's transit, NCAR scientist Brown will examine regions of the solar spectrum absorbed by Venus's atmosphere between 65 and 85 kilometers altitude. He will also construct wind patterns based on gases' Doppler shifts to reveal atmospheric composition and temperature.
Hypertrophic cardiomyopathy affects 1 in 500 adults and is the commonest cause of sudden death in otherwise fit young people. Treatment options include medication, surgery, or implantable defibrillators to relieve symptoms and prevent abnormal heart rhythms.
A University of Pittsburgh study finds that throwing athletes' shoulders differ from non-throwers', suggesting adaptations for efficient performance. Additionally, stronger hip muscles in golfers correlate with better performances. Research also highlights the importance of unplanned reactive jumps in ACL injury prevention.
A recent study published in The Lancet found that adding superficial venous surgery to compression treatment significantly reduces the risk of venous leg ulcer recurrence. The study involved 500 patients and showed a more-than-halved one-year recurrence rate among those receiving both treatments compared to those given compression alone.
