Algae are high on the genetic engineering agenda as a potential source for biofuel, and they should be subjected to independent studies of any environmental risks that could be linked to cultivating algae for this purpose, two prominent researchers say.
The cytomegalovirus (CMV) is a member of the herpesvirus family. Although most people carry CMV for life, it hardly ever makes them sick. Researchers have now unveiled long term consequences of the ongoing presence of CMV: later in life, more and more …
Scientists have developed a way to switch fluorescent molecules on and off within aqueous environments, by strategically trapping the molecules inside water-soluble particles and controlling them with ultraviolet light.
A research group is studying disease resistance in tuberculosis. The group has described the structure of a regulator that controls the expression of a pump that removes toxins from the bacteria.
A new “smart catheter” that senses the start of an infection, and automatically releases an anti-bacterial substance, is being developed to combat the problem of catheter-related blood and urinary tract infections.
A clinical study has identified an antibody that compromises the immune systems of HIV-negative people, making them susceptible to infections with opportunistic microbes such as nontuberculous mycobacteria. In this study conducted at hospitals in Thail…
Intense prep courses for the Law School Admission Test are popular for good reason: They can improve scores significantly. Now neuroscientists have revealed the underlying impact of such preparation: The brain’s neural connections change measurably, su…
The Caribbean islands have been pushed east over the last 50 million years, driven by the movement of the Earth’s viscous mantle against the more rooted South American continent, reveals new research.
On a time scale of tens to hundreds of millions of years, the geomagnetic field may be influenced by currents in the mantle. The frequent polarity reversals of Earth’s magnetic field can also be connected with processes in the mantle. New results show …
Scientists have discovered that aerosols from relatively small volcanic eruptions can be boosted into the high atmosphere by weather systems such as monsoons, where they can affect global temperatures. The massive eruption of Mount Pinatubo in the Phil…
A geoengineering solution to climate change could lead to significant rainfall reduction in Europe and North America, a team of European scientists concludes. The researchers studied how models of the Earth in a warm, CO2-rich world respond to an artif…
By affixing nanoscale gold spheres onto a microscopic bead of glass, researchers have created a super-sensor that can detect even single samples of the smallest known viruses. The sensor uses a peculiar behavior of light known as “whispering gallery mo…
