UCLA scientists design new super-hard material

Researchers at UCLA have designed a new super-hard material called rhenium diboride, which is as incompressible as diamond but can be made without high-pressure conditions. This material has the potential to replace some industrial applications of diamond and cubic boron nitride.

Why cisplatin kills breast cancer cells when other drugs fail

Triple-negative breast cancer cells are sensitive to cisplatin due to increased expression of delta-Np63 and TAp73 proteins. Cisplatin releases TAp73 from delta-Np63, leading to cell death. This study suggests using cisplatin as an early treatment option for individuals with triple-negative breast cancer.

UCR chemists identify organic molecules that mimic metals

Researchers at UCR have discovered cyclic alkyl amino carbenes (CAACs), which can mimic the behavior of metals in splitting hydrogen under mild conditions. This breakthrough could lead to the development of carbon-based systems for storing hydrogen and producing useful amino compounds.

New method predicts hip joint decay from chemotherapy

A new method predicts hip joint decay in pediatric leukemia and lymphoma survivors, with over 30% of bone deterioration linked to high risk of collapse requiring surgical repair. Researchers found that genetic or other tests may be developed to help identify at-risk patients, improving quality of life.

Stopping fatal blood clots after acute ischaemic stroke

A recent study published in The Lancet found that enoxaparin was 43% more effective at preventing venous thromboembolisms (VTEs) than unfractionated heparin. This result was consistent regardless of the severity of the stroke.

Morphine kills the pain, not the patient

A recent study found that morphine's effectiveness in pain relief does not correlate with patient survival time. In fact, patients with no opioid experience are at risk of respiratory depression, while those with moderate-to-severe chronic pain are not. This challenges the common misconception that morphine is deadly.

Novel transfusion strategy for pediatric patients in intensive care

A new study by Dr. Jacques Lacroix found that a restrictive transfusion strategy can be as safe as a liberal strategy in stable, critically ill children without increasing adverse outcomes. This approach reduced the need for transfusions and improved health care outcomes for pediatric ICU patients.
