A study of 817 patients who underwent bypass surgery found that treating depression could significantly reduce mortality rates. Patients with moderate to severe depression at baseline and those with mild depression sustained from initial to six-month assessment were more than twice as likely to die than patients who were not depressed.
Researchers uncover unexpected new role for GATA-3 in hair follicle development, shedding light on parallel molecular cues between skin and immune systems. GATA-3-deficient mice exhibit severe structural anomalies in hair development, including bent whiskers and irregular thickenings.
A recent study found that the French eat smaller portions compared to Americans, which may contribute to their lower obesity rates and healthier diets. The researchers examined portion sizes at restaurants in Paris and Philadelphia, as well as single-serve foods sold in supermarkets.
Faculty members Krishnamurthy and Keogh receive funding to improve wireless network efficiency and develop efficient algorithms for analyzing sequential data. Their research has potential applications in disaster recovery, finance, industry, and more.
Research by Dean Krahn and colleagues found that moderate drinking had no significant effect on cognitive ability in middle-aged adults, contrary to previous studies. The study used an extensive database of over 10,000 participants who completed cognitive tests at different stages of life.
The URI Metcalf Institute has awarded fellowships to two minority journalists, Rodriguez and Ortiz, to develop story ideas and receive scientific training in marine and environmental science. The fellowship aims to increase the number of minority journalists trained in science who report on science-based news.
Researchers aim to better understand the nuances of language comprehension in individuals with right hemisphere stroke, which often affects word meanings and phrases. The study will use MRI scans to determine if lesion location impacts communication deficits.
Researchers at Weizmann Institute have identified a new principle guiding brain memory systems, explaining inconsistencies in previous studies. This discovery may lead to the development of new methods for wiping out unwanted memories and treating psychological trauma.
Researchers analyzed TES observations and found trace amounts of carbonate minerals in Martian dust, indicating a thin atmosphere interacting with dust. The discovery contradicts the idea of past oceans on Mars and suggests a climate history dominated by ice and frozen water.
A team of researchers has discovered that injecting radioactive glucose can selectively kill cancer cells without harming healthy tissues. The treatment exploits the fact that cancer cells use more glucose than normal tissue, allowing for targeted delivery of radioactivity.
A study by NIH/NIEHS has identified a mouse gene linked to hydrocephalus, a common birth defect. The research team cloned the defective gene, which affects cerebrospinal fluid drainage, and found it causes classic symptoms of hydrocephalus in mice.
Scientists at Emory University Health Sciences Center have identified a new sperm protein called SED1 that plays a critical role in the initial association between sperm and egg during fertilization. Mice without this protein had reduced fertility despite normal sperm characteristics, highlighting its importance in successful binding.
A post-hoc analysis of the LIFE study found a close to 50% risk reduction in sudden death among losartan-treated diabetic patients compared to those treated with atenolol. Lars Lindholm comments that the results are exploratory and require confirmation.
Researchers discovered that the brain can associate certain stimuli with food consumption when hungry, but not after eating. This association is linked to brain regions involved in conditioning and reward pathways.
A study of Santa Cruz, Bolivia, found that replacing tropical forests with crops can increase daytime temperatures and decrease nighttime temperatures. This occurs because crops are less efficient at cooling the air through transpiration, a process where water evaporates from leaves during photosynthesis.
Researchers at Duke University Medical Center found that depression is a strong independent risk factor for death in patients undergoing coronary artery bypass surgery. Depression was associated with a doubling of the risk of death during the follow-up period, regardless of other factors.
The US is responsible for 23% of global greenhouse-gas emissions. The editorial emphasizes the need for changes in law and tax incentives to persuade citizens to use fewer fossil fuels and adopt recycling initiatives.
A genetic dictionary has been developed to understand the role of newly identified genes and their functions, which can aid in identifying unknown genes involved in cell division and cancer. The dictionary is based on gene activity data from four organisms and provides a context for understanding genetic words.
Researchers at Cornell University have confirmed a theory about how a protein complex known as FACT helps cells read their genetic code. By studying the activation of a heat-shock gene in fruit fly cells, they found that FACT and other proteins quickly move to chromosomal sites where transcription occurs.
A new combination cancer-killing drug regimen has shown promising results in extending patient survival, with 16% tumor shrinkage and 35% stable disease progression after six months. The orally administered treatment has been well-tolerated and offers a more convenient option for patients compared to traditional IV chemotherapy.
A post-hoc analysis of the LIFE study found that losartan significantly reduced sudden cardiac death in diabetic patients with hypertension and left ventricular hypertrophy compared to atenolol. The results showed a nearly 50% risk reduction in sudden death for losartan-treated patients.
This special issue aims to expand knowledge on drug supply and trafficking by providing accessible information to academic researchers. The articles cover various aspects of the topic, including a case study of a middle market drug broker and a conceptual framework for action against drug supply.
Researchers isolated a honeybee gene called csd, revealing that female bees have two different versions of the gene that form an active protein triggering female development. This discovery explains how male and female bees develop from fertilized and unfertilized eggs, respectively.
Researchers found that a combination of low-dose spiral CT and selective use of PET can effectively detect early-stage lung cancer in high-risk individuals. The study showed that lesions up to 5mm can be safely followed up after 12 months without major risks of progression.
Researchers found a clear association between ocean tides and ice stream motion in West Antarctica. The study discovered that a one-meter tide variation can cause an ice stream to halt and then accelerate rapidly.
