Don't stand so close to me: A new view on how species coexist

...00,000 generations. Parasitoid wasps, insects that kill other insects by laying eggs in them, account for a fifth of all known multi-celled species. Their 200,000 species places them approximately next to land plants in terms of diversity. To their surprise they found that over long periods of time, 'gaps...

New biosensor rapidly detects deadly foodborne pathogen

...can cause illness. Cooking would kill many of the L. monocytogenes cells that can grow at refrigeration temperature, but many ready-to-eat products, such as deli meats, smoked fish, cheeses and hot dogs, aren't always cooked by consumers before consumption, Bhunia said. ...

Low dose radiation evades cancer cells' protective 'radar'

...ude a damage detection "radar" in DNA and actually kill more cancer cells than high-dose radiation. With these findings, scientists believe they can design therapy to dismantle this "radar" sensor allowing more radiation to evade detection and destroy even greater numbers of cancer cells. Researchers at t...

Zebrafish may offer researchers powerful new tool for studying innate immunity

...er cell function." Natural killer cells sense and kill malignant cells and cells infected with certain viruses. The zebrafish, a small species of freshwater aquarium fish, increasingly serves as an animal model for the study of genetic diseases. Like humans, it has two types of immune systems innate an...

"This is particularly relevant for stem cells and other cells that can differentiate. These scaffolds offer a very good control over the envir...

Scientists pioneer biotech techniques to halt infestation of history, art treasures in tropics

...them, by identifying the natural toxin required to kill the insects decaying the papers and artifacts." Tahia Rivero, curator of the art collection held by the Banco Mercantil Foundation, says many important paintings now are known only through art books. For example, just 13 works remain from the 20-yea...

U-M researcher examines the cell's housekeeping habits

...to turn apoptosis on as a way to have cancer cells kill themselves. Being able to control autophagy may prove useful as well, Klionsky said. In fact, any kind of disease where damaged parts accumulate inside the cell might benefit from being able to control autophagy, he said. "If you could turn it on at ...

Link between immune protein and longer survival in melanoma patients identified

...atients whose T lymphocytes (the immune cells that kill tumors) carried a particular protein, or chemokine receptor, called CXCR3. Increased survival was seen in patients with Stage III metastatic melanoma, but no increased survival was noticed in patients with Stage IV, stressing the importance of ...

Powerful 'toolkit' developed for functional profiling of yeast genes

...nd "synthetic lethality" refers to genes that only kill the yeast if missing in combination. dSLAM is easier to use than the earlier version, so it's more likely to be widely adopted by the yeast research community, Boeke says. To test the new method, Pan and the team applied it to synthetic lethali...

By 2020, heart disease and stroke will become the leading cause of both death and disability worldwide, accounting for more than 20 ...

Declining fish supply linked to wildlife consumption in West Africa, Science study reports

The multi-billion dollar bushmeat industry is a key contributor to local economies throughout the developing world. It is also among the most immediate threats to tropical wildlife. The new...

In a tiny squid, bacterial toxin governs organ development

Avian cholera could spread from Great Salt Lake

...an cholera can sweep quickly through a wetland and kill thousands of birds in a single outbreak. Avian cholera outbreaks occur primarily in winter and early spring. During these times, waterfowl are usually in dense groups on wintering or staging areas and may be experiencing stress due to crowding and s...

Researchers discover defense mechanisms in some plants believed bred out by humans

So the beta-glucosidase-BGAF aggregate is involved in defense, Esen said, and behaves much like a football team that surrounds the ball carrier and keeps him from moving. The researchers' project is to understand the interaction between b...

We show that food and predators together affect measures of chronic stress in song sparrows. These inseparable effects on the individual's physiology provide a link between the well-known effects o...

...wounds or natural openings in the bark. Infections kill the inner bark and create dark-colored, elongate cankers (dead patches) on woody tissues of exposed roots, stems, and branches. Infected trees are eventually killed due to multiple cankering that girdles the tree. In 2004, a survey of 1,384 permanent...
