Smooth sailing: 'cruise ship virus' tackled by UH, Baylor College of Medicine

...ifficulties in treating Norwalk is that it is very hard to diagnose with traditional methods. "The current tests take a long time," Ruchhoeft said. "If we can build a diagnostic tool that mimics something like the pregnancy test in speed and ease of use, we could create a platform for rapid detection...

Study reveals details of mussels' tenacious bonds

...hen it comes to sticking power, marine mussels are hard to beat. They can adhere to virtually all inorganic and organic surfaces, sustaining their tenacious bonds in saltwater, including turbulent tidal environments. Little is known, however, about exactly how the bivalves achieve this amazing feat. In ...

New roles for growth factors: Enticing nerve cells to muscles

...n of target cells expressing FGF. "After a lot of hard work, we narrowed it down to FGFs and showed that they were indeed the long sought-after mysterious substance," says Pfaff. Neural stem cells can now be coaxed to develop into motor neurons in a test tube. In that artificial environment, explains Pfa...

Beekeepers work hard for the honey, despite changing tupelo forest

...Stallins said. "I don't think the public knows how hard it is to produce honey. We want more awareness of the social context of beekeeping and how environmental change and sociopolitical and economic factors play out to influence the use and access to tupelo forest." Some beekeepers say that every year ...

Tumor wizardry wards off attacks from the immune system

... by surrounding themselves with cells that make it hard for the immune system to detect them. The tumor-protecting cells are white blood cells called regulatory T cells, or T-reg for short. Under ordinary circumstances, T-reg cells inhibit immune components responsible for killing unwanted cells -- this ...

Researchers offer clues to how leaves patterns are formed

Pick up a leaf and it is hard not to notice the pattern made by the veins. For years, biologists, mathematicians and even poets and philosophers have tried to decipher the rules and regulations behind those varied designs and now new research published in part at the University o...

Diabetes hits 275 Australians each day as pandemic spreads

...we have done is to quantify the risks. We now have hard data which give our Federal and State governments the first tangible indication of the size of the problem which will burden current and future generations. These data will be instrumental in establishing priorities and calculating future budgetary n...

Pitt phage hunter takes on tuberculosis

...ne new is infected every second. TB is notoriously hard to treat, requiring a course of multiple antibiotics over six to nine months. Many people don't complete the full course of treatment, which leads to increasing antibiotic resistance against the disease. More effective treatments could be on the wa...

Researcher gives hard thoughts on soft inheritance

...rom generation to generation, what biologists call hard inheritance because the nucleotide sequence of DNA is constant and only changes by rare random mutation as it is passed down the generations. But there also is evidence, especially in plants, that non-genetic factors modifying the DNA can also be i...

Hopkins scientists show hallucinogen in mushrooms creates universal 'mystical' experience

...Griffiths. "Under unmonitored conditions, it's not hard to imagine those emotions escalating to panic and dangerous behavior." The researchers' message isn't just that psilocybin can produce mystical experiences. "I had a healthy skepticism going into this," says Griffiths, "and that finding alone was a...

Jellyfish dominate fish in over-harvested Namibian waters

...ct on the ecosystem has been hampered by a lack of hard data on jellyfish abundance. The authors note that prior to their work, less formal observations had pointed to a striking change over time--for example, jellyfish are now so numerous in the region that they significantly interfere with fishing oper...

Transgenic goat's milk offers hope for tackling children's intestinal disease

It's hard to improve on milk, but animal scientists at the University of California, Davis, have found that milk produced by transgenic goats, which carry the gene for an antibacterial enzyme found in human breast milk, altered the intestinal bacteria in young...

Triple threat polymer captures and releases

...in composed of mountains and valleys, ranging from hard to soft, hydrophilic to hydrophobic. The complex surface that is created makes it difficult for marine organisms to establish a toehold. Her laboratory has produced these novel materials and they are being used around the world Wooley and her col...

Major initiative proposed to address amphibian crisis

...rotective hair or feathers, and their eggs have no hard outer shell," Blaustein said. "So it's clear why they may be vulnerable on some levels. However, they persisted for hundreds of millions of years and just now are disappearing in many areas." Some of the causes have been identified. Rising levels ...

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

...and engineers covet the machine for characterizing hard materials, such as rocks, space dust, polymers and nanoelectronics. But in the last five years, biologists have become interested in employing it to characterize components of biological samples on a length scale of 100 nanometers or less. ''There's...

Stem cell expansion

...py of cancer). HSCs are very rare, and it is often hard to obtain enough of them for a successful transplant. To overcome this limitation, Hans-Peter Kiem and colleagues have developed a way to expand HSCs in the laboratory prior to transplantation. As they report in the international open-access journal...

Solved: The mystery of flesh-eating bacteria's relentless attack

...eason why so-called "flesh-eating" bacteria are so hard to stop. Emanuel Hanski, a microbiologist at Hebrew University in Jerusalem, and colleagues have found that the success of Group A Streptococcus is due in part to a protein that blocks the immune system's distress calls. The findings, published in...

UCSD study reveals how plants respond to elevated carbon dioxide

...mental parts of machinery," explained Young. "It's hard to predict what an instrument will do, if you don't even know anything about the parts that it is made from. Identify and characterize the parts, and you can figure out how they fit together to generate the structure of the machine, and from there yo...
