Searching the depths of the straits of Florida for disease cures

... funnels water as well as larvae and plankton from throughout the Caribbean, in all likelihood making for a unique habitat that will yield numerous interesting and potentially lifesaving samples during submersible dives as deep as 3,000 feet. The team will also conduct daily scuba dives in search of shallow-wat...

Census of Marine Life explorers surprised by diversity, density of Arctic creatures

...scientific collaboration to inventory biodiversity throughout the seas. The Healy returned to port July 26 with thousands of specimens from the Chukchi and Beaufort Seas and the Canada Basin, a vast bowl walled by steep ridges and lidded with ice. "The Canada Basin is one of the world's most isolated ocean ar...

Chronic Sinus Infection Thought To Be Tissue Issue, Mayo Clinic Scientists Show It's Snot

...ators observed an abundance of major basic protein throughout the nasal and sinus mucus in all 22 specimens, but not in the tissue. Chronic sinus infection is one of the most common chronic diseases in the United States, affecting 32 million adults, according to the National Center of Health Statistics. Chroni...

NCI Researchers Confirm the Effectiveness of Immunotherapy Approach to Treating Melanoma

...ty-five patients with melanoma that had progressed throughout the body were chosen for the study. The patients had not responded successfully when treated with standard therapies and had developed growing tumors. Blood was drawn from the patients, and then lymphocytes, a type of white blood cell in the blood th...

Community MRSA is re-emergence of 1950s pandemic, study suggests

...h hospital and community acquired infections waned throughout the 1960s as the antibiotic meticillin was used to treat these infections. Now researchers have shown that one of the key clones of community acquired MRSA (CA-MRSA) - infections picked up in public places which are resistant to treatment by powerfu...

Researchers reveal secrets of flying snakes

...e head, midpoint and vent coordinates of the snake throughout its trajectory. Socha found that the snake uses its ribs to change its body shape; it flattens from head to vent. The snake takes control of its flight by undulating through the air in a distinctive S-shape as if swimming ?moving the tail up and dow...

New understanding of cell movement may yield ways to brake cancer's spread

...ms to mammals, and likely has a conserved function throughout species. Knowing exactly what triggers cellular migration can help develop treatments that halt cancer metastasis and immune disorders like arthritis and asthma. "Previous studies by us and others have identified how a migrating cell 'gets its wheel...

Natural tumor suppressor in body discovered by UCSD medical researchers

...y found PHLPP, which they discovered was expressed throughout the body, the scientists used biochemical and cellular studies in human and other mammalian tissue to determine that PHLPP levels are markedly reduced in several colon cancer and gliobastoma human cell lines that had elevated Akt phosphorylation. Rei...

How exactly does the brain control breathing?

... what maintains this almost fail safe vital rhythm throughout life? Experimental Physiology editor Julian Paton invited two world renowned scientists Dr. Guyenet from the University of Charlottesville and Dr. Richerson from Yale University, to use the journal as a forum to discuss the issue and attempt to reso...

Studies reveal how plague disables immune system, and how to exploit the process to make a vaccine

...is, the bacterium that may have killed more people throughout history than any other infectious disease, uses to disable its host's immune system. "Yersinia pestis is the nastiest thing alive," said study author Olaf Schneewind, M.D., Ph.D., professor and chairman of microbiology at the University of Chicago a...

Stem cells in bone marrow replenish mouse ovaries

...are born with a finite stock of eggs that declines throughout life. The new report significantly extends earlier work from the same research team reporting the first preliminary evidence that ovaries of mice can be renewed with new eggs in adulthood. The new study suggests an unexpected source for the progenit...

Improved statistical tools reveal many linked loci

...the myriad elements that influence gene expression throughout an entire genome. And unlike earlier approaches to understanding how multiple loci interact, the new technique can distinguish between a group of genes with a linked subset and a group of genes with "joint linkage," where each gene site links to anot...

Study: Well-known protein helps stem cells become secretory cells

...required for the expression of the secretory genes throughout development, while Fkh appears to be required only in later embryonic stages. The group has shown that Fkh is required to maintain expression of CrebA in the salivary gland. "CrebA is the more immediate factor involved in keeping secretory genes expr...

Blink, and the brain misses it

...he light falling onto the retina remained constant throughout the blink. Many of these brain areas are activated when people become conscious of visual events or objects in the outside world. "Transiently suppressing these brain areas involved in visual awareness during blinks may be a neural mechanism for prev...

New Vaccine To Be Used For First Time In Polio Outbreak Response

... latest 18 cases occurred across five governorates throughout Yemen, including in two districts in the country's capital Sanaa and suggesting the virus had spread across the country. Ongoing field investigations have identified additional suspected polio cases across the affected governorates in Yemen. Low immu...

International Team Determines Geographic Origin of Leprosy

...reme genetic stability: all the strains of leprosy throughout the world are essentially identical. The discovery of the four SNP types could help health officials better understand leprosy in present day human populations, says Christine Sizemore, Ph.D., of NIAID's Division of Microbiology and Infectious Disea...

Researchers Discover That Microbes Can Produce Miniature Electrical Wires

...d other organisms use oxygen. They are distributed throughout the world in a wide variety of soils and sediments. Geobacter have been used to help remove contaminants from underground petroleum spills and landfill pollution of groundwater, as well as remove uranium from contaminated groundwater at a number of U...

New insight into autoimmune disease: Bacterial infections promote recognition of self-glycolipids

...viruses that, if left unchecked, would wreak havoc throughout the human body. The ability of the immune system to recognize the body's own tissues is essential, but sometimes the immune system loses the ability to distinguish "self" from potentially harmful invaders. This can lead to autoimmune disease characte...

New insights into how Huntington's disease attacks the brain

A protein in the eye may prevent immune response and protect eyes from disease

...regulatory" T cell which stops the immune response throughout the body as well as at the site where the invasion took place--in this case, the eye. In a full-blown immune response, other types of T Cells are stimulated that start the immune attack, inflammation, and tissue destruction. Since the F4/80 protein ...
