Scientists discover new species of crustacean on Lanzarote

A team of scientists has discovered a previously unknown species of crustacean, Speleonectes atlantida, in the Tunnel de la Atlantida lava tube on Lanzarote. The new species is morphologically similar to another remipede found in the same cave system and is believed to be an ancient relic isolated from the main Caribbean group.

US crop yields could wilt in heat

A study predicts that US crop yields could decrease by 30-46% over the next century under slow global warming scenarios and by 63-82% under rapid scenarios. Crop yields are most vulnerable to temperatures above 29-32 degrees Celsius, depending on the crop.

Study finds promise in combined transplant/vaccine therapy for high-risk leukemia

Researchers found that patients with aggressive leukemia had few complications and mounted a strong immune system attack after receiving a cancer vaccine shortly after a stem cell transplant. The study suggests that the approach may be more effective than traditional transplant alone, with higher survival rates.

Smoking increases risk of developing active TB

A recent study found that smoking is a significant risk factor for active tuberculosis (TB), with current smokers twice as likely to develop active TB as never-smokers. The study analyzed data from nearly 17,000 individuals in Taiwan and found that younger smokers were more likely to develop active TB.

Low-carb diets linked to atherosclerosis and impaired blood vessel growth

A study led by Beth Israel Deaconess Medical Center found that mice on low-carb diets developed significantly more atherosclerosis and had impaired ability to form new blood vessels compared to those on Western or standard diets. Standard markers of cardiovascular risk, including cholesterol, were not affected.

Still holding their breath: Mortality on lung transplant wait list remains high for some

New research finds that mortality among patients with idiopathic pulmonary arterial hypertension (IPAH) awaiting lung transplant has not decreased, despite implementation of a new allocation system. The study suggests that key prognostic indicators in IPAH are not adequately captured by the current LAS algorithm.

Researchers find saying 'I'm sorry' influences jurors

Researchers found that apologizing or using a first-person justification can result in lower frequencies of negligence verdicts against auditors. Apologies reduce the need for jurors to assign blame, while justifications influence their perception of the auditor's actions as reasonable and in accordance with professional standards.

U-M researchers discover therapeutic target that could help patients with pulmonary fibrosis

Researchers at the University of Michigan have identified a novel gene and enzyme that may hold the key to treating idiopathic pulmonary fibrosis, a life-threatening lung disease. The discovery could lead to new treatments for not only pulmonary fibrosis but also other organ-based diseases such as cardiac and kidney fibrosis.

Off-label use: Oft not evidence based

A recent national survey found that physicians inaccurately believed in the FDA approval status of 22 drug-indication pairs, including lorazepam for chronic anxiety and quetiapine for dementia with agitation. The study highlights the need for better methods to inform physicians about the level of evidence supporting off-label drug use.

Impaired transport in neurons triggers prion disease

A new study reveals that impaired axonal transport in neurons is a key factor in the development of prion diseases. The research shows that clinical symptoms correlate with reduced axonal transport in specific brain centers, providing new insights into the disease.
