Measuring the forces of biology
Biology, at the nitty-gritty level of motor proteins, DNA, and microtubules, takes its cue from physics. But while much is known about the biological components that form such cellular stuctures, researchers are only beginning to explore the physical forces between those components.

Paving the road to drug discovery
There are many disadvantages to using human cells in the initial stages of creating a new therapy. Scientists often have to test a large number of compounds in order to find one that is effective against a particular target. Human cells are costly to take care of and require a lot of time and specific conditions in order to grow. Now researchers say that fission yeast may be used to find the next cancer cure.

First atomic-level image of the human 'marijuana receptor' unveiled
In a discovery that advances the understanding of how marijuana works in the human body, an international group of scientists has, for the first time, created a three-dimensional atomic-level image of the molecular structure activated by tetrahydrocannabinol (THC), the active chemical in marijuana.

Computer simulation breaks virus apart to learn how it comes together
A computer simulation has been created that crushes viral capsids. By allowing researchers to see how the tough shells break apart, the simulation provides a computational window for looking at how viruses and proteins assemble.

New evolutionary finding: Species take different genetic paths to reach same trait
Biologists have been contemplating evolutionary change since Charles Darwin first explained it. Using modern molecular tools and fieldwork, biologists have demonstrated for the first time that different species can take different genetic paths to develop the same trait.

Chemical tags affect ability of RNA viruses to infect cells
Large swaths of DNA and its lesser-known cousin RNA are dotted by chemical tags that act like Post-It notes, providing additional instructions to the underlying genetic code. The most abundant of these RNA modifications goes by the name N6-methyladenosine, and has been implicated in a variety of biological processes. But very little is known about its role in infectious diseases. New research shows that RNA viruses are littered with N6-methyladenosine tags which affect the ability of these viruses to infect cells and, ultimately, their human hosts.

Anti-cancer effects found in natural compound derived from onions
Research has found that a natural compound isolated from onions, onionin A (ONA), has several anti-ovarian cancer properties. This discovery is a result of research on the effects of ONA on a preclinical model of epithelial ovarian cancer (EOC) both in vivo and in vitro. This research comes from the same group that found ONA suppressed pro-tumor activation of host myeloid cells.
