Are dancers genetically different than the rest of us? Yes, says Hebrew University researcher

...stein, clearly demonstrates qualities that are not necessarily lacking but are not expressed as strongly in other people: a heightened sense of communication, often of a symbolic and ceremonial nature, and a strong spiritual personality trait. Others involved in the research with Ebstein were his Ph.D. student...

Carnegie Mellon researchers discover new cell properties

...nts is stiffer than normal. However, stiffer isn't necessarily better. The stiffer lamina did protect the HGPS nucleus from some forces, but under excessive force the HGPS lamina was more brittle and eventually fractured. "The mutant HGPS lamina is like an egg shell that cracks when excessive pressure or force...

UGA study explains peaks and troughs of dengue epidemics

...anding the trends in cross-immunity, you would not necessarily predict what we observe." The researchers examined 30 years of data from the government of Thailand and from a Thai clinic that keeps what is widely regarded as the most comprehensive set of data on dengue. Southeast Asia has been a dengue hot spot...

Chocolate, wine, spicy foods may be OK for heartburn, Stanford study finds

...your heartburn. But, no, said Gerson, that doesn't necessarily seem to be the case, because simply eliminating a certain food doesn't fix the main problem of the esophageal sphincter relaxing too readily. Gerson's experiences with her patients back that up. "It's very rare to see a patient who says, 'Oh, I jus...

Survival of the selfless - scientists find cheats don't always prosper

Selfishness is not necessarily the best survival trait for microorganisms, according to researchers studying the comparative effectiveness of 'cheating' and 'cooperating' strains of yeast. Writing in the journal Nature today, the team reports that studies of lab-grown yeast popul...

Super-sized cassava plants may help fight hunger in Africa

...by the plants were just that ?bigger. They weren't necessarily more nutritious. And they would still need to be processed quickly and properly after harvesting, as the roots and leaves of poorly processed cassava plants contain a substance that triggers the production of cyanide. In previous work, Sayre helped ...

Matrilin-3 gene discovered to prevent onset of osteoarthritis

..., you still develop osteoarthritis. So there's not necessarily a link between those two," Chen says. "Maybe there's something else that causes it, such as stiff bone." Osteoarthritis affects more than 20 million Americans and is the most common type of arthritis. It is characterized by a breakdown in cartilage...

Mechanism identified for promising neurological drug

...es cells," Swanson notes. "And cell suicide is not necessarily the best thing for the whole organism." Is he being understated? The second observation, Swanson says, was made a decade ago by study co-author Tiina M. Kauppinen, PhD, currently a neurology research fellow at SFVAMC and UCSF, when she was a graduat...

Combined treatment extends life expectancy for lung cancer patients

...s cells ?reaching the center of the tumor, but not necessarily killing all the cells at the edges. This can lead to a recurrence of the tumor, and the cancer may spread. Thermal ablation is delivered directly to cancerous cells with the guidance of a diagnostic image showing the tumor's location. However, if som...

New roles for growth factors: Enticing nerve cells to muscles

Fertility hope as study shows eggs survive in older ovaries

...the phenomenon of egg regeneration in mice did not necessarily mean the same happened in humans. "But the mechanism could provide direction for ovarian stem cell research and help women with fertility conditions," he said. One in six Australian couples faces some form of infertility. Due to the limitations and ...

New strategy developed to combat West Nile Virus

...n said. "And simply having more mosquitoes doesn't necessarily mean that we'll experience a greater incidence of West Nile Virus. The mosquitoes themselves must first be infected with the virus. Researchers call the process through which more mosquitoes become infected 'amplification,' and there are a number of ...

Biotech cotton provides same yield with fewer pesticides

Contrary to common wisdom, scientist discovers some mammals can smell objects under water

...ing whiffs of interesting odors underwater doesn't necessarily mean they smell them. So Catania devised some additional tests. One of the complicating factors was the star-nosed mole's unusual nose, which is ringed by a star-shaped set of fleshy appendages. It uses its star like a super-sensitive set of finge...

Quality not quantity important for immune response to HIV

...s of Health in the US has found that bigger is not necessarily better, contrary to conventional medical wisdom. The research may have a profound impact on the development of a vaccine against the disease. "Conventional medical wisdom tells us that the bigger the immune response, the more effective it will be in...

Caterpillars tell us how bacteria cause disease

His study focuses on bacteria called Photorhabdus asymbiotica which is known to infect both insects and humans. Dr Waterfield and his team have fragmented the genome for thi...

Newly discovered behavior in cancer cells signals dangerous metastasis

...ors are highly complex in their behavior and don't necessarily need a gene mutation to alter their behavior," said Sebastian Oltean, M.D., Ph.D., research associate and first author of the journal article. "Alterations in gene splicing can be much more subtle in nature but still have a major impact on the canc...

HIV gets a makeover

...apies and vaccines that are effective on SIV don't necessarily translate into human success. Now, using a combination of genetic engineering and forced adaptation, researchers at Rockefeller and the Aaron Diamond AIDS Research Center have created a version of the AIDS virus that replicates vigorously in both hum...
