Sex and the heart: It's not what you think

...m used data on men and women 40 and older from two broadly representative samples of the US population, approximately 10 years apart. Among the findings: High risk blood pressure - both diastolic and systolic - increased in women but decreased in men. Medication against hypertension appeared to be more...

Carnegie Mellon scientists use 'green' approach to transform plastics manufacturing

...ie Mellon. Developed by Matyjaszewski, ATRP is a broadly adopted process that allows the production of specialty polymers for coatings, adhesives, lubricants, cosmetics, electronics and numerous other markets. ATRP's strength lies in its ability to combine chemically diverse subunits (monomers) into multip...

Natural anti-viral enzyme helps keep cancer cells alive, researchers find

...n Achilles' heel of cancer cells that's apparently broadly conserved among many types of solid tumors." Using cultured human cells, the researchers set out to study enzymes known to be involved in keeping cancer cells alive and proliferating. They soon narrowed the focus to one called RalB. This molecule i...

Hundreds of thousands of viral species present in the world's oceans

...hat the world's oceans hold a few hundred thousand broadly distributed viral species, with some species-rich regions likely harboring the majority of these species. ...

Novel computed imaging technique uses blurry images to enhance view

...ng within the sample. "ISAM has the potential to broadly impact real-time, three-dimensional microscopy and analysis in the fields of cell and tumor biology, as well as in clinical diagnosis where imaging is preferable to biopsy," said Boppart, who is also a physician and founding director of the Mills Bre...

Researchers create artificial enzyme that mimics the body's internal engine

...people study it. It's quite complex, and it's been broadly ignored." Each electron is brought to the enzyme one at a time, Collman said: "It's like a bucket brigade in a Western movie." But the electrons are consumed too fast to study individually, he noted. Therefore, the researchers had to invent a tech...

Scientists unveil piece of HIV protein that may be key to AIDS vaccine development

...rom this specific antibody, known as b12, that can broadly neutralize HIV. "Creating an HIV vaccine is one o... multiple HIV strains. Scientists have sought such broadly neutralizing antibodies by studying the blood of people whose immune systems appear to hold the viru...

Angelman syndrome deficits rescued in mice

...se UBE3A is a "housekeeping" gene, meaning that it broadly regulates cellular processes not particularly specific for any of the neurological deficits seen in these children. Specifically, the protein encoded by UBE3A "tags" other proteins for degradation by the cellular "garbage disposal," the proteasome. ...

The quest for an effective HIV vaccine presents new possibilities, challenges

...h priority to creating an HIV vaccine that induces broadly neutralizing antibodies, which might prevent the establishment of HIV infection. Although rare, such antibodies do exist, giving hope to scientists that a vaccine to induce such antibodies can be designed. Drs. Johnston and Fauci conclude that a ...

Soils offer new hope as carbon sink

... applied as compost, mulch or crop residue. "We broadly categorise carbon in the soil as being labile (liable to change quickly) or stable – depending on how quickly they break down and convert into carbon dioxide," he said. "Labile carbon like crop residue, mulch and compost is likely to last two or t...
