Elevated fasting blood sugar in pregnancy linked to harmful outcomes for mothers, babies

A new study by the University of Alberta found that pregnant women with elevated fasting blood sugar levels are at a higher risk of complications, including large babies, high blood pressure, and preterm births. Despite receiving diabetes drug treatments, these women were more likely to experience adverse outcomes.

Planned hydropower dams threaten fish in the tropics

The study maps the impact of current and future river dams on fish habitats worldwide, revealing that habitat fragmentation will increase by a quarter or more in tropical regions like the Amazon, Niger, Congo, Salween, and Mekong river basins. This will disrupt the life cycles of freshwater fish species, causing extinction risk.

Building a safer CAR-T therapy

Researchers have devised a new type of chimeric antigen-receptor (CAR) T cell that can be reversibly inactivated with small molecules, offering novel solutions to the safety concerns of CAR-T therapies. The 'STOP-CAR-T' system has been shown to work as well as traditional CAR-T systems and can be controlled by an approved drug.

Hepatitis B: New therapeutic approach may help to cure chronic hepatitis B infection

Researchers at Helmholtz Zentrum München developed a novel therapeutic approach to cure chronic hepatitis B infection. By knocking down the expression of the virus' proteins, they enabled successful vaccination with TherVacB, a novel therapeutic vaccine. The therapy aims to cure existing chronic diseases by activating immune cells.

Scientists discover new non-sticky gels

Researchers at the University of Bristol have discovered a new class of material, 'non-sticky gels,' that forms when colloidal particles behave as liquid crystals. This breakthrough enables the development of gel formulations with improved mechanical properties and longer shelf-life, addressing a major limitation in many products.

Life in dead wood

Research project in Ebrach Forest investigates optimal dead wood placement to promote biodiversity, with sun-exposed trunks showing rare species but also numerous shaded species. The study was funded by €500,000 and will run until 2023.

Study demonstrates liquid biopsy as effective predictor of stage III melanoma relapse and treatment

A study published in Clinical Cancer Research found that circulating tumor cells were associated with a decrease in relapse-free survival at six months, and this association persisted at a 54-month longer-term follow-up. This suggests that CTC assessment may be useful in identifying patients at risk for relapse who could benefit from m...
