Study: Cancer cells grown in culture dishes have less parity with their human sources

In a bid to find or refine laboratory research models for cancer that better compare with what happens in living people, Johns Hopkins Medicine scientists report they have developed a new computer-based technique showing that human cancer cells grown in culture dishes are the least genetically similar to their human sources.

Researchers explore relationship between life expectancy and lifespan equality

Special diets, exercise programs, supplements and vitamins -- everywhere we look there is something supposed to help us live longer. Maybe those work: human average life expectancy has gone from a meager 40-ish years to a whopping 70-something since 1850. Does this mean we are slowing down death?

Toxicant profile of BAT's modern oral products is comparable to nicotine replacement therapies

New research published today indicates that BAT's modern oral (MO) products in the form of tobacco-free nicotine pouches have a toxicant profile that is comparable to nicotine replacement therapies (NRTs) and much lower than traditional oral snus, a category of products that, when used as the sole nicotine product is already established as a reduced risk product compared with cigarettes.

New transparent material can capture respiratory droplets effectively from air

Although plexiglass barriers are seemingly everywhere these days -- between grocery store lanes, around restaurant tables and towering above office cubicles -- they are an imperfect solution to blocking virus transmission.

Scientists decipher the activation mechanism of a chemokine receptor

Chemokine receptors, located at the surface of many immune cells, play an important role in their function. Chemokines are small proteins that bind to these receptors and control the movement and behavior of white blood cells.

Researchers identify properties that enable proteins to remember and respond to pressure

A new rubber band stretches, but then snaps back into its original shape and size. Stretched again, it does the same. But what if the rubber band was made of a material that remembered how it had been stretched? Just as our bones strengthen in response to impact, medical implants or prosthetics composed of such a material could adjust to environmental pressures such as those encountered in strenuous exercise.

Study finds molecular switch that controls the ability of organisms to adapt to low nutrient levels

Getting energy and nutrients from the environment - that is, eating - is such an important function that it has been regulated through sophisticated mechanisms over hundreds of millions of years. Some of these mechanisms are only now beginning to be unraveled.
