Oil spill impacts may perturb entire food webs

A new study reveals oil spills can alter the structure of aquatic food webs, leading to increased fish populations like menhaden in the Gulf of Mexico. The research found that the loss of top predators reduced predation on forage fish, resulting in a surge in their abundance after the 2010 Deepwater Horizon blowout.

Patients whose emergency surgery is delayed are at higher risk of death

A new study published in the Canadian Medical Association Journal found that patients experiencing delayed emergency surgery are at a higher risk of death and have longer hospital stays. The delays were primarily caused by staff and operating room unavailability, highlighting the need for spare capacity to ensure timely access to care.

New research offers hope to neuro-tumor patients

Scientists from the University of Plymouth have discovered that cellular prion protein is over-produced in schwannoma cells, contributing to tumor growth and patient prognosis. The study identified existing drugs that could manage this protein overproduction and potentially lead to an effective therapy for neurofibromatosis 2 patients.

Blood vessels are not designed to fight infection

Researchers discovered that endothelial cells lining blood vessels are not as effective at removing invading bacteria via xenophagy, a process used by epithelial cells. The study suggests that targeting the ubiquitination pathway could lead to new approaches for fighting infections like GAS.

Going to extremes to predict natural disasters

Researchers at KAUST have developed a systematic method for comparing the accuracy of different types of simulation models for predicting extreme events. The study found that nonparametric methods are more flexible but limited to small dimensions, while parametric methods can handle higher-dimensional problems but are sensitive to errors.

Killing cancer in the heat of the moment

Researchers from Kyoto University developed a new method to transfer genes into cancer cells using gold nanorods coated with oleate and DOTAP. The nanorods are activated by near-infrared laser heat, inducing cell death in surrounding cancer cells.

Hubble's hidden galaxy

Located close to the Milky Way, IC 342 is a sweeping spiral galaxy with an active core. The Hubble Space Telescope image reveals a mixture of hot star-forming regions, cooler gas, and dark dust lanes around the bright core, indicating the presence of ionized hydrogen.

Baits may be bolstering bear populations

Baits have become a significant portion of black bears' diets, potentially bolstering population density. The widespread consumption of calorically rich foods may be driven by the goals and consequences of baiting policies needing re-evaluation.

Zero gravity: Graphene for space applications

Researchers are testing graphene's potential in space applications through two experiments. GrapheneX, a student-led team, will use microgravity conditions to test graphene for light sails, while another experiment investigates how graphene improves efficiency in loop heat pipes, crucial for satellite cooling systems.

Childhood obesity major link to hip diseases

Research from the University of Liverpool reveals a strong association between childhood obesity and hip diseases, particularly Slipped Capital Femoral Epiphysis (SCFE). Obese children are at highest risk of developing SCFE, which can cause significant pain and lead to hip replacement in adolescence or early adulthood.

'Educating' patients' immune cells may help combat diabetes

New research suggests that educating patients' immune cells with cord blood stem cells may help combat type 1 and 2 diabetes. The therapy is safe and effective in improving islet beta cell function, making it a potential treatment for other autoimmune diseases.

Family-based treatments may help address obesity in children

A family-based treatment approach for childhood obesity was found to be effective in reducing body mass index standard deviation scores. Young age and high BMI-SDS at baseline, as well as good motivation for treatment and adherence to the protocol, were key factors associated with successful weight loss.

Well-being in later life: The mind plays an important role

A recent study found that psychosocial factors such as depression and anxiety disorders have a stronger negative impact on subjective well-being in older adults. The researchers analyzed data from over 3,600 participants aged 73 and found that women living alone were more likely to experience low well-being.

Simple test predicts return of bladder cancer

A simple test for bladder cancer has been developed that can predict its return in over 80% of patients, identifying the faulty protein TERT. This new method detects bladder cancers earlier than existing tests and distinguishes them from urinary tract infections, potentially helping doctors start treatment sooner.
