Making Spider-Strength Materials

Researchers have been trying to make artificial spider silk--a lightweight, tougher-than-steel material that could have countless industrial applications--for decades. In an important step toward that goal, researchers at Tufts University have created genetically engineered microbes that produce... Read More

High-fiber, low-fat diets cultivate healthier intestinal microbes, study suggests

African children who eat a high-fiber diet (and the occasional wood-digesting insect) have gut bacteria that help them digest plant fibers and protect them from diarrhea and inflammatory disease, a new study finds. The research may lead to new probiotics that improve the digestive health of West... Read More

Cells survive lasers and nanoblasts in new drug delivery method

Using chemical "nanoblasts" that punch tiny holes in the protective membranes of cells, researchers have demonstrated a new technique for getting therapeutic small molecules, proteins and DNA directly into living cells.

Carbon nanoparticles activated by bursts of laser light trigger the tiny ... Read More

DuPont and USDA partner on new tests for E.coli

DuPont and USDA will be developing a test for the detection of "Big 6" non-O157 shiga toxin-producing E. coli pathogens in food, which in recent years have been identified as agents of food-borne illnesses. The O157:H7 STEC strain of E. coli is already associated with global food contamination o... Read More

Oil Spill Causes Record Gulf Dead Zone

Scientists say this year that the "dead zone" area that forms every summer in the Gulf of Mexico is one of the largest ever measured.

The large area of low oxygen that chokes marine life comes in addition to the massive BP oil spill.

Microbes that eat the oil can deplete oxygen in the wate... Read More

Mud from deepest place on Earth could hold key to cures

In a bid to search for new drug discoveries, researchers are using one of the world’s most advanced microscopic scanners to study bacteria taken from mud samples recovered from the deepest place on Earth – the Mariana Trench.

The findings could pave the way for the creation of life-saving dru... Read More

Tracing Oil Reserves to Their Tiny Origins

In 1913, as the automobile zoomed into American life, The Outing Magazine gave its readers a bit of background on what fueled the new motorcars in “The Story of Gasoline.” After a brief vignette describing the death of “old Colonel Stegosaurus Ugulatus,” the article explained that “yesterday you...

'Genome mining' may yield new drugs

Prospecting for new drugs in the genes of common bacteria could yield a "treasure trove" of therapeutic compounds, an expert has said.

Eriko Takano's team of bug experts already discovered a promising new antibiotic using the "genome mining" approach.

The drug was extracted from the soil b... Read More

Compound Conundrum: Chemists Turn to Modified Microscope to Fathom Deep-Sea Mystery Molecule

Chemists at times look to plants, sea life and other natural sources for the basic ingredients needed to develop the next breakthrough medicine. Unfortunately, nature is not always willing to easily part with its secrets, forcing scientists to rely on sophisticated imaging technology—nuclear mag... Read More

Scientists finding how crucial bacteria can be to health

For all the antibacterial products and other weapons in the war against germs, even the cleanest of us still carry about 10 bacterial cells for every human cell.

Most are harmless or even beneficial. Indeed, some scientists believe that the loss of friendly organisms in recent years could be ... Read More
