Marsh-dwelling mole gives new meaning to the term 'fast food'

...ly reverse themselves one out of three times. This inefficient behavior suggests that the moles are operating at, or near, the limit set by the speed which the mole's nervous system can process touch information, the researchers conclude. "If additional research confirms that this is the case, then these little...

Promising anti-TB compound finally can be synthesized with ease

...ition and subsequent removal of functional groups, inefficient and lengthy procedures that Davies noted have resulted in producing only very small amounts of the compound. In addition, he explained, conventional methods fail to control the synthesis of the desired three-dimensional shape of the natural pr...

Urgent measures needed to retain our lead in pharmaceuticals

...,"Pharmaceutical drug development is a lengthy and inefficient process with new drugs failing to reach the market due to issues with efficacy, safety, and what has become known as "pharmacokinetics". Tufts Centre for the Study of Drug Development reports that R&D costs for an innovative new drug approved in 2001...

Researchers figure out how hearts fail

...they don't remedy the fact that the heart is still inefficient because a lot of oxygen is necessary for it to drive the same amount of contractile activity. "Many forms of heart diseases have many pharmacological therapeutic approaches to treat it. But heart failure is a difficult one. If you're diagnosed with h...

Green catalyst destroys pesticides and munitions toxins, finds Carnegie Mellon University

...said Collins. "Existing detoxification methods are inefficient and work only under acidic conductions. Our method can be used over a much broader pH range, including wastewater pH conditions." Fe-TAMLs already have shown promise in killing a simulant of a biological warfare agent (anthrax), reducing fuel pollu...

...erybody does in (tropical regions) is an extremely inefficient way to maintain and promote species diversity." Howe hopes the project -- which he expects will run for 20 years or more -- will attract additional funding sources. And he predicts close academic collaboration between UNAM and U.S. ecology programs l...

APS physics tip sheet #53

... immune system has apparently evolved to be mildly inefficient so that it achieves a balance between quick response to disease and decreased probability of attacking the body's own tissues. The authors drew their conclusions from a model of the dynamics of antibody evolution. Their simulations show that while th...

DOE publishes roadmap for new biological research for energy and environmental needs

...facture of ethanol from cellulose by replacing the inefficient and expensive processes used today. They could enable smaller-scale and more cost-effective and energy-efficient distributed processing plants that could make ethanol cost competitive with oil-based gasoline. Thousands of microbial species have bio...

Comments, experts and background on the 2005 Nobel Prize in Chemistry

...mplex molecules that were previously difficult and inefficient to make. Their research has opened the door to faster, more efficient and greener methods for developing new drugs and polymers. Metathesis reactions were first recognized in the 1950s but were poorly understood at the time. Diligent work by the Nob...

Plants reveal a secret and bring researchers nearer a cleaner future

...ffices is an unaccomplished dream due to the still inefficient technology for a better use of solar energy. The study of photosynthesis in plants could provide new clues by explaining how they absorb almost 100% of the sun-light reaching them, and how they transform it into other forms of energy. Researchers Mic...

Hanayama was awarded a predoctoral fellowship from the Japan Society for the Promotion of Science in 2002 and received his Ph.D. degree and the Yamamura Award from Osaka University in 20...

A new focus for the mechanism of nerve growth

...," said Forscher. "FSM see that this was caused by inefficient recycling of actin filaments at the back end of the actin network treadmill." Recycling of actin bundles at the ends of structures called filopodia was most strongly affected. This is important because filopodia are thought to play a key sensory rol...

Light activated anticancer drug targeted to DNA using cisplatin like sub-units

...tems had to find the DNA within the cell, an often inefficient process. Now we have added the DNA targeting drug," Brewer said. "We were working on cisplatin analogs before, so we have tied it to light activated systems." Cisplatin begins its interaction with cancer DNA by binding to the nitrogen atoms of the DN...
