Disease without borders

Researchers present a bioregional guide that combines place-based city planning and ecosystem management to address wide-ranging human health challenges along the US-Mexico border. The approach aims to promote healthy placemaking, taking into account environmental exposures, stress, diet, urban design, and behavior.

Progress in materials science

Researchers have published a detailed appraisal of Friction Stir Welding (FSW), a complex welding technique that can join difficult-to-weld materials. The study concludes that FSW has the potential to be increasingly valuable in modern industry, but scientific understanding is still at an early stage.

Protein 'map' could lead to potent new cancer drugs

Researchers at Imperial College London have created a 'global map' of proteins modified by the disease-causing enzyme N-myristoyltransferase (NMT), identifying over 100 previously unknown substrates. The study holds promise for new cancer treatments, with a potent drug-like molecule already identified to block NMT's activity.

Sensitive youngsters

A long-term laboratory experiment showed that young sea stars grow more slowly and eat less in acidic conditions, even after a prolonged acclimation period. The study suggests that young sea stars may not adapt to the effects of ocean acidification, potentially affecting entire ecosystems.

Green light for clever algae

Guillardia theta's unique phycobiliproteins have distinct biosynthesis and assembly processes compared to cyanobacteria and red algae. Researchers gained insight into the complex transport mechanism of these pigments using docking enzyme GtCPES.

Protecting the body from itself

Researchers have established a crucial relationship between Natural Killer T (NKT) cells and B cells in the body's natural defense mechanisms. The study found that altered lipid compositions on autoimmune B cells lead to over-activation of NKT cells, causing their depletion. Removing a specific lipid-presenting molecule from B cells re...

USC researchers discover dual purpose of cancer drug in regulating expression of genes

Researchers at USC Keck Medicine have discovered a dual purpose of the cancer drug decitabine in regulating gene expression. The study found that the drug not only reactivated tumor suppressor genes but also down-regulated overexpressed oncogenes, which are responsible for cancer progression. This new mechanism may provide additional t...
