Ultrasound can make stronger 3D-printed alloys

Researchers used ultrasound to shake metal alloy grains into tighter formations during 3D printing, resulting in improved tensile strength and yield stress by 12%. The technique can be applied to various commercial metals, enabling the production of high-performance structural parts or structurally graded alloys.

New insulin compound could improve therapy for diabetes patients

Scientists have developed a non-fibrillating form of human insulin called glycoinsulin, which demonstrates the same glucose-lowering effects as native insulin without fibril formation. This discovery presents a promising solution for patients relying on insulin pumps and could improve the shelf life of insulin products.

Heart disease linked to a higher risk of kidney failure

A new study found that cardiovascular diseases, including heart failure, atrial fibrillation, and coronary heart disease, are each linked with a higher risk of developing kidney failure. Adults hospitalized with heart failure had an 11.4-times higher risk of developing kidney failure than individuals without cardiovascular disease.

First patient for Parkinson's disease trial recruited

A UK-wide trial has started recruiting patients for a three-year study on preventing falls in people with Parkinson's disease, led by the Royal United Hospitals Bath NHS Foundation Trust and the University of Bristol. The trial will test whether a commonly prescribed dementia drug can prevent debilitating falls and improve patients' qu...

New study shows 'organic' wounds improve produce

A recent study published in Scientific Reports found that simple leaf wounding in plants can increase the production of healthier organic fruit. The research team discovered that stress responses created in the fruits and vegetables lead to an increase in antioxidant compounds prior to harvest, making them healthier for human consumption.

Break point

Researchers found that DEHP disrupts meiosis in worms, leading to defects during egg formation and early embryonic development. The chemical causes excessive DNA breaks and interferes with the system that repairs them, resulting in abnormal chromosomes and reduced embryo viability.

Two drugs used in combination prove to be effective against most aggressive asbestos cancer in mice

Researchers at CNIO have identified a potential effective treatment for sarcomatoid mesothelioma, the most aggressive type of asbestos cancer, using two existing drugs in combination. The study found that blocking MEK and PI3K pathways reduces the growth and invasiveness of mesothelioma cells in mice.

Catalytic protocells get zingy

Researchers have developed artificial cells capable of decomposing hydrogen peroxide and generating oxygen, as well as implementing a rudimentary chemical signalling pathway between the cells. The new protocells use a combination of synthetic and biological catalysts to create multi-functional activity.

Nanobubbles in nanodroplets

Scientists have observed the ultrafast reaction of nanobubbles in helium droplets after extreme ultraviolet radiation (XUV) excitation. The findings help understand how nanoparticles interact with energetic radiation and decay, essential information for directly imaging individual nanoparticles.

The calm of the deer

A study found that lynx reintroduction in Europe led to changes in deer behavior, with humans influencing their day-night rhythm. Deer reduced daylight movements by 1.37 when faced with human disturbances, while the presence of lynx increased daytime activity.

Study shows protein inhibitor as potential treatment approach for common mutations found in non-Hodgkin lymphomas

A study at University of Texas M.D. Anderson Cancer Center showed a potential new approach to treating follicular lymphoma and DLBCL through manipulation of molecular programs controlled by CREBBP. Inhibition of HDAC3 restores immune programs lost as a result of CREBBP mutations, paving the way for immunotherapy approaches.
