Biologists have discovered the first of a new class of cellular motor proteins that “rewind” sections of the double-stranded DNA molecule that become unwound, like the tangled ribbons from a cassette tape, in “bubbles” that prevent critical genes from being expressed.

A new discovery by London biologists may yield new ways of handling transplant rejection. Scientists confirm the two-way transfer of a molecule that instructs the immune system to tell “self” from “non-self.” By disrupting the transfer of this molecule, newly transplanted organs should become “invisible” to the host’s immune system. Such an advance would be [...]
Researchers have succeeded in growing roots on plants at places where normally leaves would grow. This important step in plant modification can be highly beneficial for improving crop yields and efficiency in agriculture.

In a twist on nontraditional uses of ultrasound, neuroscientists have developed pulsed ultrasound techniques that can remotely stimulate brain circuit activity. The findings provide insights into how low-power ultrasound can be harnessed for the noninvasive neurostimulation of brain circuits and offers the potential for new treatments of brain disorders and disease.

Does your personality influence who you vote for? The short answer is yes, according to one professor of psychology. As Americans go to the polls in record numbers to vote for the next U.S. president, some voters will crave social stability and others will crave social change. Liberals and conservatives divide according to these personality [...]

During the time it takes you to read this article, something will happen high overhead that until recently many scientists didn’t believe in. A magnetic portal will open, linking Earth to the sun 93 million miles away. Tons of high-energy particles may flow through the opening before it closes again, around the time you reach [...]

According to new research, the degree of change in blood triglyceride levels following a fatty meal may indicate susceptibility to diet-induced obesity. The findings open doors to new methods of identifying people, including children, who are at risk for becoming obese.
Like humans, bees’ ability to learn appears reduced when they are ill. The prediction was that good learners would be worse at fighting infections — but surprisingly, this was not the case.
Scientists have been puzzled by the fact that high levels of plasmin in blood and high levels of urokinase in artery walls are linked to high risk for rapid progression of atherosclerosis and heart attacks. Are these naturally occurring clot busters contributors to disease or evidence of the body’s attempt to fight it? Molecular biology [...]
