When given the chance to pay less, patients choose cheaper prescription drugs

As prescription drug spending continues to rise in the United States, along with prices for new and well-established drugs, insurers, employers and patients are searching for ways to cut...

How cytoplasm 'feels' to a cell's components

In a study that may guide drug design, researchers find organelles encounter varying levels of resistance, depending on their size and speed, as they move through a cell’s cytoplasm....

Hormonal tug-of-war helps plant roots navigate their journey through the soil

A sophisticated mechanism that allows plant roots to quickly respond to changes in soil conditions has been identified by an international research team. Source: Science Link: Hormonal tug-of-war helps...

Gravity, 'mechanical loading' are key to cartilage development

Mechanical loading is required for creating cartilage that is then turned to bone; however, little is known about cartilage development in the absence of gravity. Now, bioengineers have determined...

miR-122 target sites in liver cancer: study links three genes to patient survival

A new study shows that a molecule that regulates liver-cell metabolism and suppresses liver-cancer development interacts with thousands of genes in liver cells, and that when levels of the...

Speeding up chemical screening to prioritize toxicity testing

Researchers have developed a high-throughput technique that can determine if a chemical has the potential to activate key genes in seconds rather than the typical 24 hours or more....

Microreactor made to study formation of methane hydrate

Researchers are using a novel means of studying how methane and water form methane hydrate that allows them to examine discrete steps in the process faster and more efficiently....

ShAPEing the future of magnesium car parts

A new process should make it more feasible for the auto industry to incorporate very lightweight magnesium alloys into structural components. The method has the potential to reduce cost...

No microbes? No problem for caterpillars

Caterpillars have far less bacteria and fungi inhabiting their gut than other animals and the microbes that inside them seem to lack any identifiable role, aside from occasionally causing...

How humans and their gut microbes may respond to plant hormones

A bowl of salad contains more than vitamins and minerals. Plant matter also includes remnants of the hormones plants produce to control how they grow, age, and manage water...
