Rice bioengineers pioneer techniques for knee repair

... the international Biomedical Engineering Society, helped pioneer the development of coin-sized scaffolds in the early 1990s that are now the state-of-the-art clinical option for repairing small defects in articular knee cartilage. His lab is also working on techniques to grow replacement knee menisci, the...

Hyena mothers give their cubs a helpful dose of hormones

... National Science Foundation manager whose program helped support this work, "this is a clear example of how the complex integration of genetics, physiology and social environment leads to reproductive success for this species." Wolff believes that Holekamp's work will create a paradigm shift in how scient...

Mute swan population helps explain longstanding evolutionary question

... an increase in protection from predators may have helped enable the swans to evolve towards a new, larger clutch size. ...

Cell therapy slows progression of an inherited neurological disease; Improves motor skills in mice

...d in producing myelin. The transplanted cells also helped lead to production of healthy myelin and improved motor coordination. "There is much excitement in the field of cell-based therapy and this study is a clear indication of its potential," says Mahendra Rao, MD, PhD, at Johns Hopkins School of Medicin...

Scientists a step closer to protecting world's most important crop

...Last year scientists from The University of Exeter helped to complete the sequence of the rice blast fungus genome, which has aided the current research. ...

Protecting endangered species helps reduce poverty

... aimed at conserving the rare Ganges river dolphin helped the community to address critical basic needs such as clean water. After five years, the number of families below the poverty line significantly declined. The report further shows that more than 60 percent of people living around Uganda's Bwindi Im...

Scientists one step closer to cancer vaccine

Scientists at Karolinska Institutet in Sweden have helped to identify a molecule that can be used as a vaccination agent against growing cancer tumours. Although the results are so far based on animal experiments, they point to new methods of treating metastases. The results are presented in the online edi...

HortResearch science reveals the natural potential of apples

...d." Dr Ferguson said the EST database has already helped expand scientific understanding of apple, enabling HortResearch scientists to identify a key gene involved in apple colour expression. "Further work with the database will undoubtedly yield even more exciting advances in the future." Releasing the ...

Sea coral's trick helps scientists tag proteins

The glow emitted by a variety of sea coral helped Russian scientists harness the protein that generates the light to create a tiny fluorescent tag that responds to visible light. The two-color tag should help researchers follow individual proteins as they dart around inside living cells. Under a mi...

A new way of looking at molecular motors

...motor neck and tail evolved together. That finding helped them define some of their new categories. Organisms employ all three types of motors at the same time, but in different proportions. For example, yeast uses six kinesins, five myosins, and one dynein while mammals have genes for more than 40 kinesi...

New antimicrobial compound adheres to skin to promote healing

... without being toxic. Already, the treatment has helped heal Spirit, a burned dog in a high-profile animal cruelty case, and Gasper, a beluga whale at the Georgia Aquarium in Atlanta. The researchers envision a human application for the technology, which they're currently seeking to patent. Dr. Bran R...

Scientists identify molecular structure of key viral protein

... disease. "The development of antiviral drugs is helped by knowledge of the structure, shape and mechanism of the target molecules, which is what we can now provide for the F protein," said Theodore S. Jardetzky, professor of biochemistry, molecular biology and cell biology, who co-led the study. "Knowing...

Congenital rubella syndrome nearly eradicated in the US

...more effective vaccine introduced in the 1970s has helped in eliminating transmission of rubella from expectant mothers to their unborn babies. "Effectively, congenital rubella syndrome has been nearly eradicated from the United States," according to the statement. There were fewer than 10 cases or rubell...

DNA end caps may lead to cancer treatments, UT Southwestern researchers report

...d for their work on telomeres and telomerase. They helped develop an anti-telomerase drug that helps slow the spread of lung cancer cells in mice. The drug is being tested in humans to see if it's safe. The researchers say that any anti-telomerase drug would not be used alone to treat cancer. Rather, it w...

A case of mistaken molecular identity

...ptor on the surface of heart cells, a finding that helped explain why Chagas patients develop certain heart problems. Now, it turns out, molecular mimicry can also upset the delicate machinery inside retinal cells. Levin and his team found that antibodies geared to attack T. cruzi also block rhodopsin, a m...
