BC catalyst discovery promises faster, cheaper drug production

...oratory syntheses." The discovery is based on the concept of chirality, which refers to the two-handed nature of certain molecules. Many important chemical compounds that exist in nature or are created by laboratory scientists come in two, mirror-image forms ?a "left" and a "right" hand. Some drugs comprise...

'Best of both worlds' -- Targeting a single gene could inhibit bone decay and stimulate bone growth

...le simultaneously stimulating bone formation. This concept may lead to drug treatments for osteoporosis and other bone diseases. Senior author Yongwon Choi, PhD, professor of Pathology and Laboratory Medicine at the University of Pennsylvania and colleagues report their findings in the December issue of Natu...

Research holds promise for herpes vaccine

...h toward a human vaccine. "I'd like to take this concept from the chalkboard to the clinics," he said. ...

Chemical tests of cell growth enter third dimension

...t of the two new technologies, Yang took the basic concept behind the FBB and combined it with laboratory testing methods that normally only grow cells in two dimensions. Such tests are normally done on cells in trays containing many tiny wells. Each well contains a growth medium and some cells, and a prote...

UVa researchers seek to unlock broccoli's cancer fighting secret

...t comes in a pill or liquid form could enhance the concept of stopping cancers before they start. For Cross, there is also a personal pull to developing anti-cancer compounds. "The real irony is that I can't stand broccoli," she says. ...

Cardiologist's 'living chip' changes science of disease monitoring

...ime? It may sound like science fiction, but this concept is moving toward reality at Physiologic Communicat...s from academia and upstate New York industry. The concept has seen strong support from individuals such as Terry Gronwall, an entrepreneur-in-residence at the...

Study offers window into human behavior, brain disease

...y abundant in humans, and the finding supports the concept that evolution has rendered the human brain vulnerable to disease, including frontotemporal dementia, and, possibly, disorders such as autism and schizophrenia, the researchers say. In addition, because the disease erodes aspects of social behavio...

Stormy days ahead for coral reefs

...xtreme weather. The research introduces a new concept ?colony shape factor (CSF) ?to translate the myriad shapes and sizes of coral colonies onto a simple scale that measures their vulnerability to dislodgment. Any severe event, like a cyclone, imposes a threshold that can be scored on the same scale, ...

Parental genes do what's best for baby

...her parent is silenced by a chemical stamp.? The concept of imprinting has long puzzled scientists as it appears to undermine the natural benefits organisms gain from inheriting two sets of genes. If one copy of a gene is damaged, for instance, then the second copy can compensate; imprinted genes lose t...

With record resolution and sensitivity, tool images how life organizes in a cell membrane

... what's in that cell membrane. Boxer compared the concept to learning about people sitting in chairs in a room to the organization of individual molecules in a membrane. ''If you look at the room, you want to be able to see not just the chair but also what kind of chair it is... and I want to see who is nea...

A surprise about our body clock

...on for patients who suffered a heart attack." This concept is central to the exciting new field called regenerative medicine which aims to restore, repair and regenerate damaged organs rather than merely treating the symptoms of disease. According to Dr. Weisel, "One treatment resulting from this discovery ...

OHSU study says stem cell 'fusion' occurs in tumors

...ing cell fusion in tumors and we believe that this concept is an underappreciated mechanism for promoting tumor growth. Our findings have implications on how tissues regenerate and how, in the process of this regeneration, cells may become prone to future problems. " Although the tumor in her study did not ...

Healing the heart with bone marrow cells

...on for patients who suffered a heart attack." This concept is central to the exciting new field called regenerative medicine which aims to restore, repair and regenerate damaged organs rather than merely treating the symptoms of disease. According to Dr. Weisel, "One treatment resulting from this discovery ...

K-Staters design and build a low-cost remote sensing tool for environmental studies

...example, one square section." Schinstock said the concept of using the sensing tool for nonmilitary applications opens up many possibilities for collecting reliable data in tricky or dangerous settings, such as studying dispersal of a smoke plume during a prairie fire; checking smokestack emissions; countin...

Tigers get a business plan

...ific numbers over a specific time period, is a new concept for conservationists. "We're putting our reputations on the line and holding ourselves accountable that we can grow tiger numbers," said Rabinowitz. "At the same time, we have the knowledge, expertise and track record to accomplish this goal." Th...

Scientific issues associated with carbon-neutral energy sources such as cellulosic ethanol

...linois at Urbana-Champaign. Somerville noted the concept that CO2 emissions may negatively affect climate are not new. "In 1895, Arrhenius presented a paper to the Stockholm Physical Society titled, On the Influence of Carbonic Acid in the Air upon the Temperature of the Ground in which he argued that in...

Science captures the essence of fruit

...ions." HortResearch has proven the bioproduction concept can be used to produce fruit flavours and fragrances by perfectly recreating a fruit compound called alpha-farnesene, responsible for the distinctive aroma of green apples. The company has filed international patent applications on the use of the a...

Unique dual target specificity of kinase inhibitor key for success against cancer

...e in cancer progression. This study reinforces the concept that successful small molecule kinase inhibitors must display a broad reactivity to effectively attenuate the complex signaling pathways involved in malignant transformation and to thwart to the ability of cancer cells to adapt to stress. Lipid kin...

Coming soon: 3-D imaging that flies 'through' and 'around' cancer

... findings are exciting, the researchers proved the concept rather than validated the technique. Future validation studies will be conducted and software tools need additional development, said Quon, who indicated that the technique might be expanded to include other tracers and anatomic regions besides the c...

Cells use mix-and-match approach to tailor regulation of genes

...anscription factor binding patterns by borrowing a concept from computer science. The team considered the binding of one transcription factor to one gene as analogous to one "hop" of a data packet from one Internet router to another. In the case of gene regulation, Ideker's team identified "2hop" relations...
