Researchers estimate that seaweed globally sequesters 173 trillion grams of carbon per year, with 90% of this being due to transport into deep-sea sediments. This highlights the significance of seaweed as a major carbon sink, surpassing Amazonian forests.
Scientists have recovered ancient DNA from a West Indian mammal known as the 'Island Murderer,' tracing its evolution back to 70 million years ago. The study sheds light on the impact of humans on recent extinctions in the Caribbean.
A study has discovered a new mechanism in the mouse brain that regulates obesity, finding that Rap1 gene inhibition can reduce body weight and improve leptin sensitivity, potentially leading to a new therapeutic target for treating human obesity.
Research from the Center for BrainHealth found that smokers' beliefs about nicotine content impact their brain's response to smoking. The study used fMRI scans to show that participants who believed a cigarette contained nicotine experienced different neural activity compared to those who believed it didn't.
Researchers found that capillary forces from soap foam induce pressure gradients near the container walls, reducing sloshing motion. The dampening effect happens faster than expected exponential decay, causing the waves to stop after a finite time.
Researchers found that pharmacological and genetic RANK pathway inhibition significantly reduced recurrences and metastases in a mouse animal model of breast cancer. This suggests RANK inhibitors used in osteoporosis treatment may also be effective against breast cancer.
Patients undergoing transcatheter aortic valve replacement are at increased risk of developing infective endocarditis, with younger age, male sex, and diabetes mellitus being significant risk factors. The study found a high rate of in-hospital mortality and 2-year mortality rates, highlighting the need for preventive measures.
Researchers at The Wistar Institute discovered that BET inhibitors can suppress PD-L1 activity, a major therapeutic target in various tumors. This approach may reduce side effects while enhancing the immune response against cancer.
UCSB researchers create high-performance tunable dielectrics using molecular beam epitaxy, overcoming material quality issues. The advancement enables adaptive electronic systems with potential applications in cellular communications and phased-array antennas.
Researchers found that Klebsiella pneumoniae siderophores play a crucial role in facilitating invasive infection by triggering inflammation and activating HIF-1 alpha, allowing bacteria to spread from the lungs to the spleen. The study suggests that therapies targeting siderophore production could provide a two-pronged attack against K...
Researchers assess safety, tolerability, and clinical use of graded aerobic treadmill testing in young athletes with sports-related concussion. The study confirms physiological recovery in 63 patients and improves symptoms in most cases.
A study found that implementing an analytic tool to allocate clinical care costs and quality measures led to significant improvements in value of care for three designated outcomes. The program resulted in reduced costs and improved quality, with notable decreases in hospitalist laboratory testing and sepsis management.
The Second Panel on Cost-Effectiveness in Health and Medicine developed new recommendations to improve the quality of cost-effectiveness analyses. The key changes include performing analyses from two reference case perspectives and providing an impact inventory to clarify included consequences. These updates aim to promote the continue...
Researchers have successfully created healthy baby mice by injecting sperm into embryos developed from non-egg cells, achieving a success rate of up to 24 per cent. This breakthrough challenges the long-held dogma that only egg cells can support embryonic development.
A study published in JAMA compared five-year survival rates after endosonography and mediastinoscopy for mediastinal nodal staging of lung cancer. The endosonographic strategy was found to be more sensitive for diagnosing mediastinal nodal metastases.
Biomedical researchers need to replicate results in multiple animal models and report negative data to ensure reproducibility. Experts propose strategies such as holding public discussions, developing accountability metrics, and improving methods reporting.
