Fungal factories may save hemlock forests

... unmistakable to turkeys and deer (and hunters): a thick understory of duff, deep with shade that accentuates the black furrows of the hemlock's tannin-rich bark. In winter, chickadees eat the small seed cones of the hemlock and they are only one species of many that depend on the hemlock not just for fo...

Vanishing beetle horns have surprise function

... as a sort of can opener, helping them bust out of thick larval shells. The finding will surprise anyone who assumed hornless Onthophagus adults (usually the females) never form the horns in the first place. They do, the scientists say, but the nubile horn tissue is reabsorbed before the beetles' emerge...

Early Earth haze may have spurred life, says University of Colorado study

... in that it has an atmosphere -- in this case one thick with organic aerosol particles that form through photochemical processes when sunlight reacts with methane gas, she said. According to the study, a similar haze hanging over Earth early in its history could have supplied more than 100 million tons ...

Researchers identify molecule that causes destructive lung inflammation in cystic fibrosis patients

...y's cells, leading to the production of abnormally thick mucus. The thickened mucus can affect many organs and body systems, including the sinuses and lungs, pancreas, liver, gallbladder, intestines, and reproductive and sweat glands. In the sinuses and lungs, this thickened mucus allows bacteria that woul...

Newly discovered proteins associated with cystic fibrosis

...he normally thin protective layer of mucus becomes thick and very difficult to move. It is very difficult for the patient to cough up the thick mucus, so the airways get clogged. The trapped mucous becomes a haven for infectious agents, which l...

Bee genome information housed at Texas A&M University

...ail work. Johnston likened that work to having a thick book written with only four of the 26 letters of the alphabet all in one long sentence. The researchers' task is to learn how to punctuate and read that language by identifying key words, sentences and chapters within that book. Many scientists have ...

Space radiation threats to astronauts addressed in federal research study

...ch shelters could include cylindrical "cocoons" of thick shielding material for astronauts to crawl in or shelters lined with thick tanks filled with water, since water is not only essential for space travel but also contains large ...

Mars Express and the story of water on Mars

...ow the surface. Inside this impact structure was a thick layer of possibly water-ice-rich material. "We are finding reservoirs of ice that have never been seen before," says Plaut, "But we are still puzzling out when and where the water on Mars was liquid." "The last MARSIS observations have been done o...

Binghamton University researcher makes major biofilm dispersion breakthrough

...anic polymers that can grow to several centimeters thick and cover large areas, spells all kinds of big trouble. Biofilms, for instance, fog your contacts, help to rot your teeth, and cause a host of diseases from cystic fibrosis and ulcers to colitis and ear infections. They are a leading cause of hospi...

This would allow it to be pumped more easily and economically through pipelines to onshore storage tanks where it would then return to its natural viscous condition....

Insect predation sheds light on food web recovery after the dinosaur extinction

...esearchers found nearly 200 different species with thick leaves and drip tips, indicating a tropical rainforest completely unlike the other Paleocene floras. This site was on the eastern slope of the Paleocene Front Range, and Johnson and Ellis' work, as well as recent paleoclimate modeling simulations, h...

3-D model reveals secrets of metastasis

...y of Texas at Austin. "In 3D, cells move through a thick jungle of fibers, or "vines" TM , that hinder forward progress." Cells must either squeeze through or chop up these putative vines to get anywhere. As a result, they move slower in three dimensions. In an interesting twist, all cells need at leas...

Within the building's courtyard, de Grummond said, is a freestanding sandstone platform that likely served as an altar. A few feet away, she and her students unearthed "the most fascinat...

Study shows our ancestors survived 'Snowball Earth'

...as widespread, it probably was not consistently as thick as a half-mile, he said. "That kind of ice coverage chokes off photosynthesis, so there's no food for anything, particularly eukaryotes. They just couldn't survive," he said. "But this research shows they did survive." Buick and colleagues studied dr...

DNA: Bacteria's survival ration

...g the chemical stability of genetic material. If a thick layer of DNA were exposed to the sun, he said, only molecules at the top would break down chemically, while bacteria would eat the rest from the bottom up. Nevertheless, Finkel said, DNA remains a backup nutrient for bacteria, being harder to digest ...

However, neither the kinetics nor the forces involved were known, simply because discharge is so fast that it had not been previously resolved by conventional high-speed imaging. To clarify these issues, the researchers studied nem...
