Egg P bodies protect maternal gene messages
A cell decides what proteins to make based on the messages it receives from its genome. Sometimes messages are held back to be read later, and in most cell types these delayed messages are stored and eventually marked for destruction in P bodies (processing bodies). view more (2008-08-11)
Pesticides choke pathway for nature to produce nitrogen for crops
Many farmers applying pesticides to boost crop yields may instead be contributing to growth problems, scientists report in a new study. view more (2007-06-06)
New computing tool could lead to better crops and pesticides say researchers
A new computing tool that could help scientists predict how plants will react to different environmental conditions in order to create better crops, such as tastier and longer lasting tomatoes, is being developed by researchers. view more (2009-09-23)
Targeting key proteins of carcinogenesis
Misfolded and disused proteins are eliminated by a cellular shredder called the proteasome. The cell labels the proteins it wants to dispose with Ubiquitin (Ub) in order to avoid the unwanted degradation of still needed proteins. view more (2007-06-25)
Lifeburn - heating systems for domestic application
Heating systems must adjust the thermal power to the needs of the user through the modulation of their thermal power. So a major efficiency, less polluting emissions and more comfort can be obtained. However, the difficulty to develop new radiant burners has slow down the appearing of new equipments. A solution for this problem was proposed in a... view more... (2002-09-23)
Novel regulation of the common tumor suppressor PTEN
PTEN is one of the most commonly mutated tumor suppressor genes. It is an antagonist for many cellular growth, proliferation and survival processes. When mutated or deleted, it causes cancers of the prostate, breast, colon, and brain. view more (2007-01-12)
New drug candidate against HIV developed in Sweden
As a part of a research collaboration, scientists at the Sahlgrenska Academy at Göteborg University, Sweden, have developed a new drug candidate against HIV-infection. view more (2005-06-30)
Study of Latina women and children finds large variation in susceptibility to pesticides
Some newborns may be 26 to 50 times more susceptible to exposure to certain organophosphate pesticides than other newborns, and 65 to 130 times more sensitive than some adults. view more (2006-03-03)
Gene exchange common among sex-manipulating bacteria
Certain bacteria have learned to manipulate the proportion of females and males in insect populations. Now Uppsala University researchers have mapped the entire genome of a bacterium that infects a close relative of the fruit fly. view more (2009-03-26)
Bran filters chlorinated hydrocarbons and arsenic out of waste water
Compounds of arsenic and hexachlorocyclahexane (HCHs) previously occurred above all in the production of pesticides. Pesticides containing HCHs have been prohibited in Germany since the 1980s. Arsenic is still used in the semiconductor and glass industries and pollutes water and the soil in many places. Since HCHs and arsenic are carcinogenic... view more... (2002-10-11)
New way to control protein activity could lead to cancer therapies
Investigators at the Stanford University School of Medicine have found a way to quickly and reversibly fine-tune the activity of individual proteins in cells and living mammals, providing a powerful new laboratory tool for identifying - more precisely than ever before - the functions of different proteins. view more (2008-09-29)
Arsenic discharged from landfills, says Dartmouth research
A group of researchers at Dartmouth have studied the concentrations of toxic metals at the former Coakley Landfill in North Hampton, N.H. They've found that while the level of iron and some other contaminants decreased, the level of arsenic slightly increased. view more (2005-12-05)
Holistic Study Approach Expands Understanding of Agricultural Chemicals in the Environment
An understanding how environmental processes and agricultural practices interact to determine the transport and fate of agricultural chemicals in the environment is essential for effectively addressing the widespread degradation of surface and ground waters from past, present, and future agricultural activities. While considerable research has... view more... (2008-06-04)
Smaller isn't always better: Catalyst simulations could lower fuel cell cost
Imagine a car that runs on hydrogen from solar power and produces water instead of carbon emissions. While vehicles like this won't be on the market anytime soon, University of Wisconsin-Madison researchers are making incremental but important strides in the fuel cell technology that could make clean cars a reality. view more (2009-09-18)
Mustard - hot stuff for natural pest control
Researchers, growers and Industry specialists from 22 countries will share the latest research into the use of Brassica species, such as mustard, radish, or rapeseed, to manage soil-borne pests and weeds - a technique known as biofumigation. view more (2008-07-28)
Red alert! How disease disables tomato plant's 'intruder alarm'
How a bacterium overcomes a tomato plant's defences and causes disease, by sneakily disabling the plant's intruder detection systems, is revealed in new research out today (4 December) in Current Biology. view more (2008-12-05)
Humans may be losers if technological nature replaces the real thing
There are Web cams focused on falcons, ferrets and fish, virtual tours of the Grand Canyon and Yosemite, and robotic dogs, seals and even dinosaurs. But what about the real deal: observing animals in their natural habitat, hiking the John Muir Trail or a playing with a live pet? view more (2009-04-02)
Watermelon's hidden killer
Watermelon vine decline (WVD) is a new and emerging disease that has created devastating economic losses for watermelon producers in Florida. Caused by the whitefly-transmitted squash vein yellowing virus (SqVYV), the disease created monetary losses estimated at $60 to $70 million in Florida during the 2004 growing season. view more (2009-09-08)
Using microbes for the quick clean up of dirty oil
Microbiologists from the University of Essex, UK have used microbes to break down and remove toxic compounds from crude oil and tar sands. view more (2009-09-08)
RNA interference toward MMP-2 may be an effective therapeutic strategy for cancer
The invasion or metastasis of pancreatic cancer has been known to be a complex process involving many molecular mechanisms, of which proteolytic degradation of extracellular matrix (ECM) exerted by matrix metalloproteinases (MMPs) was considered to be an essential step. view more (2009-03-09)
