Can a keto diet help protect brain energy?

Researchers found that a high-fat, low-carb ketogenic diet can improve brain health and stop or slow cognitive decline in individuals with the APOE4 gene. This study suggests that precision nutrition tailored to an individual's genotype, gut microbiome, gender, and age may be more effective than a one-size-fits-all approach.

Acidic tumor environment promotes survival and growth of cancer cells

Researchers found that cancer cells in a tumor environment with acidosis can switch to more efficient energy production, using networks of mitochondria instead of fragmented structures. This adaptation helps cancer cells survive under adverse conditions, and could lead to new treatments targeting the energy metabolism of tumors.

Portable sensor detects synthetic cannabinoids in e-cigarettes and biological fluids

Researchers developed a portable sensor to detect synthetic cannabinoids in e-cigarette liquids and biological fluids, allowing for early intervention and harm reduction. The device shows high selectivity and sensitivity, detecting concentrations as low as 0.2 µM and identifying specific peaks that quantify substances present.

Early planting to avoid heat doesn’t match current spring wheat production

Researchers at Washington State University found that early planting to avoid heat damage may actually hinder spring wheat productivity due to other growth issues. The study used computer modeling to show that moving crop plantings earlier in the season can expose crops to elevated heat or cold stress in later growth stages.
