The first global analysis of infant cereals sold in lower-income countries highlights the need for basic quality assurance services to improve nutritional consistency and healthy growth of infants from 6 to 24 months of age.

You’ve likely heard about being in the right place at the wrong time, but what about having the right genes in the wrong environment? In other words, could a genetic mutation (or allele) that puts populations at risk for illnesses in one environmental setting manifest itself in positive ways in a different setting?

Researchers have designed molecules with the potential to deliver healing power to stressed cells — such as those involved in heart attacks. The research, at a cellular level in the lab, involves organic molecules that break down to release hydrogen sulfide when triggered by oxidative stress.

One of the main reasons cancer remains difficult to treat is that cancer cells have developed a multitude of mechanisms that allow them to evade destruction by the immune system. One of these escape mechanisms involves a type of immune cell called myeloid-derived suppressor cells (MDSCs). A recent study provides new insight into how MDSCs […]

Mutations that have been linked to endometrial cancer can be found in the uterine lavage fluid of pre- and post-menopausal women both with and without detectable cancer.

Many scientists have attempted to tackle how climate change will affect the natural world by determining the thermal tolerance of various species, then predicting what will happen to them as our world warms. However, this approach as a way to understand nature has its drawbacks because one species never acts alone, so comprehending how global […]

Scientists introduce method to identify regulatory sequences in RNA by analyzing their regulatory function in a massive parallel reporter assay during embryogenesis. The method is called RESA (RNA Element Selection Assay).

Scientists have studied three closely related pupfish species peacefully co-existing because each, through subtle jaw size differences, has rapidly carved out its own food niche within the last 10,000 years. They have matched DNA changes with differences in jaw size to uncover candidate genes responsible, along with evidence supporting the role of large-effect alleles in […]

Bacteria that are susceptible to antibiotics can survive when enough resistant cells around them are expressing an antibiotic-deactivating factor. This new take on how the microbial context can compromise antibiotic therapy was just published by a team of microbiologists.

Marijuana use increased and the drug’s perceived harmfulness decreased among eighth- and 10th-graders in Washington after marijuana was legalized for recreational use by adults but there was no change among 12th-graders or among students in the three grades in Colorado after legalization for adults there, according to a new study.
