Scientists are examining which genetic characteristics of rice best control the growth of a common weed.

The growth of rice (Oryza sativa L.) is of great agricultural importance but it is affected by the common weed, barnyardgrass (Echinochloa crus-galli). Scientists from the Department of Crop Science at Konkuk University examined the use of rice allelopathic potential for weed control.

A laboratory bioassay using water extracts was conducted to determine the alleopathic p

More than 220 ideas for making European scientific endeavours and policies better known, understood and more attractive to the young and to the public at large are published today on the Web by the European Commission’s research and innovation information service CORDIS (www.cordis.lu/eoi/science-society/).

These ideas, initiated by citizens, public and private bodies, research and civil society organisations, as well as by the media, in 29 countries, represent the impressive results from a

European scientists are formulating conclusions for mine-water management right now

Next to mine waste, water contamination by mines poses a problem to which far less attention is paid to. Today and tomorrow the group of European scientists of the ERMITE project are gathered at the Netherlands Institute of Ecology (NIOO-KNAW). On this very moment, they formulate their guidelines for new European legislation and sustainable water management in mines. In November, the official meeting

Populations of fungi blanketed by Colorado’s snows are more active and diverse than previously thought, and are likely responsible for the productivity of the tundra ecosystem they are a part of, according to findings by scientists funded through the National Science Foundation (NSF)’s Long-Term Ecological Research (LTER) and Microbial Observatories programs. The researchers have published their results in this week’s issue of the journal Science.

UCLA astronomers report they have detected remarkably stormy conditions in the hot plasma being pulled into the monstrous black hole residing at the center of our Milky Way galaxy, 26,000 light years away. This detection of the hot plasma is the first in an infrared wavelength, where most of the disturbed plasma’s energy is emitted, and was made using the 10-meter Keck II Telescope at the W.M. Keck Observatory in Hawaii.

Plasma is a hot, ionized, gas-like matter — a fourth state of ma

A DNA sequence that acts as a throttle to control the rate at which an enzyme moves along the DNA has been observed by researchers at UC Davis. By controlling the activity of the RecBCD helicase enzyme, the “Chi” sequence can affect how efficiently genes are repaired.

RecBCD unwinds the DNA double helix so that the genetic code can be read, copied or repaired. This unwinding is an essential first step in most processes involving DNA.

The research findings, which are published in t
