Cul-de-sac effect: Why Mediterranean regions are becoming more prone to extreme floods in a changing climate

New research reveals that prolonged accumulation of rain over several days, fueled by mountains blocking moisture from the Adriatic Sea, causes extremely rare floods. The study identifies a 'cul-de-sac' effect, where stationary cyclones channel humid air toward vulnerable regions, increasing flood risk.

Missing nutrient in breast milk may explain health challenges in children of women with HIV

A new UCLA study reveals that breast milk from women living with HIV contains significantly lower levels of tryptophan, an essential amino acid important for infant immune function and brain development. The study suggests that this depletion may be a common denominator explaining the immune, growth, and cognitive differences seen in c...

Genome-wide analysis of gene expression in sorghum furthers efforts to improve stem biomass

Researchers have identified genes with organ-preferential expression in sorghum stems, revealing distinct temporal functional signatures and potential candidates for genetic engineering applications. These findings offer valuable insights into improving sorghum stem biomass and composition for bioenergy and biopolymer production.

Molecular insights and targeted therapies are transforming breast cancer treatment

Recent discoveries in breast cancer biology highlight the potential of targeted therapies and molecularly guided treatment approaches. The review discusses various treatments, including monoclonal antibodies and immunotherapies, as well as challenges in treating triple-negative and HER2-positive breast cancers.

China's cropland acidification has ceased—but recovery is slow

A new study published in Nature Geoscience reveals that China's cropland soils have stabilized in pH levels since 2013, linked to agricultural policy reforms. However, recovery has been slow and uneven across different types of farmland, with paddy fields showing signs of improvement but dryland soils remaining acidic.
