Lost dogs found more often than lost cats, study suggests

...r visit the shelter," Lord said. One of the best ways to locate a pet may be to post a sign in the neighborhood, the study showed. Posted signs resulted in the return of 15 percent of recovered dogs and 11 percent of found cats. Six dogs (4.5 percent) and two cats (3 percent) made it home because of a...

Producing medicines in plant seeds

...icker and Geert De Jaeger- have been searching for ways to have plants produce useful proteins efficiently. Plants do offer a lot of advantages over conventional production methods. Because production with plants doesn't require expensive high-tech laboratories, scientists anticipate that, by working with...

Applied scientists create wrinkled 'skin' on polymers

...sensors and microfluidic devices and may offer new ways to build custom-made cell templates for tissue engineering. The work is a collaboration among researchers at Harvard University and Seoul National University. The Harvard group consisted of John W. Hutchinson, Abbott and James Lawrence Professor of ...

New synthetic self-assembling macromolecules mimic nature

...ir, teeth, or skin. But when scientists devise new ways for molecules to self assemble into new materials, it is an important achievement. Researchers with the Macromolecules and Interfaces Institute (MII www.mii.vt.edu ) at Virginia Tech report such a development in the online issue for the Journal of ...

Strawberry daiquiris -- the extra-healthy cocktail?

... even healthier, scientists show. While exploring ways to help keep strawberries fresh during storage, researchers from Thailand and the US discovered that treating the berries with alcohol led to an increase in antioxidant capacity and free radical scavenging activity within the fruit. While such a boos...

Cancer researchers add spice to research against rare neuromuscular disease

... substances that turn on the receptor, we look for ways to attack the faulty receptor directly. In this experiment, for instance, the mice treated with ASC-J9 have normal fertility and are completely healthy sexually, which wouldn't be the case if we simply took away testosterone." ...

Researchers uncover protection mechanism of radiation-resistant bacterium

...chronic or acute doses of radiation; could lead to ways to protect cancer patients from the toxic effects of radiation therapy; and may prove significant in efforts to contain toxic runoff from radioactive Cold War waste sites. Fifty years ago, scientists discovered D. radiodurans, leading to speculati...

Flavanols in cocoa may offer benefits to the brain

...vanol-rich cocoa may impact health in a variety of ways not previously known,?said symposium organizer Harold H. Schmitz, Ph.D., chief science officer at Mars, Incorporated, which helped sponsor today’s symposium and has supported research on cocoa flavanols for more than 15 years. “The findings raise th...

Gene chips forecast ecological impacts of climate change

...rine ecosystems. The main focus will be on finding ways to assess the effects of temperature stress and low pH, due to ocean acidification, on adults and early developmental stages of marine invertebrates. Coastal marine ecosystems, from the intertidal zone to the continental shelves, are particularly...

New bird, bat species revealed by extensive DNA barcode studies

...by radiation. This suggests there are many natural ways for animals and humans to heal themselves. Also, he and his colleague Oksana Iavorovska discovered that human ovarian endometriosis is induced in sun-lovers by the ultraviolet radiation in sunlight. "It’s been a privilege for me to do my work for...

Cancer that colonizes our bodies

...by radiation. This suggests there are many natural ways for animals and humans to heal themselves. Also, he and his colleague Oksana Iavorovska discovered that human ovarian endometriosis is induced in sun-lovers by the ultraviolet radiation in sunlight. "It’s been a privilege for me to do my work for...

Scientists uncover new target in cancer mutation puzzle

... while other researchers, for example, are seeking ways to normalize a faulty gene such as p53, which is i...taking the opposite approach. They are looking for ways to stop tumors by interfering with features of cancer cells dependent upon p53 and Ras mutations. ...

Buckyballs used as 'passkey' into cancer cells

...Viruses, which are often toxic, long ago developed ways of sneaking through cell walls. While we're mimicking some techniques used by viruses, we're using non-toxic pieces of protein, and we're incorporating buckyballs as a passkey." The passkeys that Barron and colleagues developed contain a molecule ...

New test for most virulent HPV strains under study

... higher-grade abnormalities. “These are the two ways to use HPV testing,?says Dr. Ferris. “One is as a primary screening adjunct test with a Pap test for women age 30 and older and the other is as a triage test when women have an abnormal Pap smear result.? An HPV test typically follows an ASC-US Pap...

Can engineered immune cells stop AIDS?

... looks promising, researchers are still working on ways to manipulate these elusive bone marrow cells and ...notherapy for HIV-Infected people, as well as find ways to prevent it all together." ...

Tiny clue reveals new path toward heart disease

...Further study of this new clue could lead to novel ways to treat or even prevent the disease, the researchers said. "The ultimate goal is to determine who will develop cardiovascular disease," said lead study investigator Liyong Wang, Ph.D., a research associate at the Duke Center for Human Genetics. ...

Leukemic cells find safe haven in bone marrow

...ana said. "This insight will help researchers find ways to disrupt this safe haven for leukemic cells that need asparagine," added James R. Downing, M.D., St. Jude scientific director and chair of the Pathology department. Downing is a co-author of "The Journal of Clinical Investigation" paper. The "ASNS"...

Scientists unravel clue in cortisol production

...m from fulfilling their roles. "One of the best ways to try and figure out the function of a protein or a gene is to get rid of it or mutate it so that it's not acting normally. Then you compare it with one that is acting normally," said Sewer. In this study, they focused on a protein known as steri...

National Academies advisory: Invasive aquatic species in the Great Lakes

...information on trade in the Great Lakes region and ways to eliminate further introductions of nonindigenous aquatic species into the lakes by vessels traveling the St. Lawrence Seaway. The committee's final report will comment on the strengths and weaknesses of various options and recommend those that see...

Short chromosomes put cancer cells in forced rest
