Biotechnology's newest chemical tool

...f the IST programme, the CYBERHAND project aims to hard wire this hand into the nervous system, allowing sensory feedback from the hand to reach the brain, and instructions to come from the brain to control the hand, at least in part. Coordinated by Professor Paolo Dario with Professor Maria Chiara Carro...

New discovery: If it weren't for this enzyme, decomposing pesticide would take millennia

...tion and natural selection can do." Although it's hard to predict, the work may have implications for people designing enzymes later on, he said. Using enzymes in reactions can greatly reduce the cost of a lot of chemical processes. Finding the enzyme in bacteria in fields never before exposed to the pe...

Wright bros. upstaged! Dinos invented biplanes

.... Such long feathers around the feet would make it hard for Microraptor to run on the ground, says Chatterjee, supporting the idea that it was a tree dweller, thus reinforcing the trees-down theory. ...

Polymer gel can block toxic leakage problem in gene therapy

... high viscosity of that jello-like mixture made it hard to inject. "The bottom line is that when people try to do gene therapy on cancer they must inject the genes into the tumor," Yuan said. "One way would be to try and inject the genes into the bloodstream. But that won't work because the virus particl...

Scientists move forward understanding of schizophrenia

... said: "Over the past few years we've been working hard to help in the development of medicines for treating asthma and chronic obstructive pulmonary disease by inhibiting very similar enzymes to PDE4B. It has been so exciting to work together with the Edinburgh and Merck groups in finding this new link ...

Rutgers researchers scientifically link dancing ability to mate quality

...iate professor of anthropology. "But this has been hard to study because of the difficulty of isolating dance movements from variables, such as attractiveness, clothing and body features. By using motion-capture technology commonly employed in medical and sports science to isolate dance movements, we can ...

Key brain regulatory gene shows evolution in humans

...g to do with cognition. But beyond that, it's very hard to make a clear argument about specifically what that role is. "We do know that not making enough prodynorphin causes clinical problems, but we don't know what having more of it did for us humans. We're hoping the clinical psychiatrists and psycholo...

Many needles, many haystacks

... screw goes. Linear motifs are so small that it is hard to tell what features allow them to bind to other ... there is often a common motif," Neduva says. "The hard part is finding a 3-to-8 'letter' pattern in a protein sequence that may be thousands of amino acids...

Engineered Stem Cells Show Promise For Sneaking Drugs Into The Brain

... Parkinson's. But the drug, which is expensive and hard to obtain, had to be pumped directly into the brains of Parkinson's patients for it to work, as it is unable to cross the blood-brain barrier. In an effort to develop a less invasive strategy to effectively deliver the drug to the brain, Svendsen's ...

Nano springs eternal; Protozoan 'engine' posts nano records

...forming a tight coil. To find out how fast and how hard Vorticella recoils, France and colleagues used modern microscopes and tools to measure the force and speed of the spring. This is one powerful engine, France reports. The spasmoneme's contraction is measured in nano-newtons of force and centimeters/s...

'Computer-chemistry' yields new insight into a puzzle of cell division

...search. "It's very exciting. I think it's a really hard problem." A successful docking between the two enzymes not only requires the "active sites" -- where chemical reactions occur --on the phosphatase and the kinase to link precisely, Rudolph said. The two molecules' component parts, or "residues," mus...

Marsupial genome reveals insights into mammalian evolution

...icient because their genes can be so similar it is hard to pinpoint regions that remain unchanged because they serve a particular purpose. In contrast, comparison of distantly related genes, such as the chicken and human, can be difficult, because the sequences are so different." "Marsupial and monotreme...

Bones from blood: Scientists aim to break new ground on fractures

...ear similar to bone marrow stem cells but they are hard to locate. We aim to isolate and expand them so we have enough cells to use in therapies. "We also want to compare them with bone marrow and embryonic stem cells and investigate how we can turn them into bone structures for use as 3D bone replacemen...

Free HIV tests cheaper than charging when goal is preventing AIDS

... "They are a remarkable group of women doing the hard work of taking care of AIDS patients for the long-term. They asked us to provide an HIV testing program as a means of promoting behavioral changes, and that's really the genesis of this project," Thielman said. The KIWAKKUKI program started offerin...

'Virus chip' detects new virus in prostate tumors

...inning," Ganem says. "Pathogen discovery is really hard work." The team intends to carry out epidemiology studies to determine how widespread the virus is, how it is transmitted, and whether it causes any of the prostate tumors, or any other disease. The gene-hunting technique DeRisi and Ganem call the ...
