The secret to longevity in tubeworms

... of bacteria and archaea that live in the deep sea cold sediments surrounding the seep where the worm lives. These chemoautotrophs use energy from hydrocarbons to reduce sulfate to sulfide, which L. luymesi absorbs through its unique "roots," extensions of its body that it tunnels into the sediments. Howe...

The secret lives of whales

... Because of their ability to break down lipids in cold water, these animals and their bacterial garden may hold a key to better cold water washing detergents. But more importantly, study of whale worms and other whale-fall species he...

Dinosaur DNA? New Patent Covers Degraded DNA recovery

...ves criminal investigators another tool to re-open cold cases or revisit crime scenes, stringing together strands of detached DNA into a genetic trail that could solve a crime or exonerate the falsely accused," says Dr. Ensley. This patent is part of a scientific progression that began in 1989 when DNA w...

Breast-Cancer Risk Linked to Exposure to Traffic Emissions at Menarche, First Birth

...urrogate for total PAH exposure. Cruise emissions, cold engine emissions and intersection emissions were used to estimate total traffic PAH emissions. In addition, meteorological information was used in a geographic dispersion model to determine PAH exposure at each participant's residence. While the re...

World-first Living Donor Islet Cell Transplant A Success; Procedure Offers Promise For Diabetics

...nors. Those islets are often severely injured from cold storage, transport time and the pancreas is severely damaged by toxins which circulate in the blood stream after brain death." "Our expectation is that these islets from near-perfect organs will work better, although it's too early to tell," he says...

Researchers discover molecular mechanism that desensitizes us to cold

...d how the membrane protein that allows us to sense cold works and how this protein becomes desensitized so... Neuroscience, focused on a specific region of the cold receptor which is found in many other receptors, including ones involved in taste, vision and fertil...

Chemists identify immune system mechanism for methamphetamine binges

...ng over-the-counter drug ingredients, particularly cold and allergy medicines. Available as a powder or crystal, the drug can be injected, snorted, swallowed and smoked to provide users with a sense of euphoria. Drug effects can last for up to 12 hours. Frequent use is associated with serious health probl...

WHO Warns Of Increased Risk Of Vector-borne Diseases In Tsunami-affected Areas

...ng on the skin or from the nose or gums, sweating, cold skin are danger signs. If any one of them is noticed, the patient should be taken to a hospital immediately. * The patient should be given fluids to drink during transfer to the hospital. * The patient should be provided nutritious food and f...

New lab technique identifies high levels of pathogens in therapy pool

...actices, including closed doors and windows during cold periods, said Pace. Since the study, the rate of air exchange in the pool area has been increased and additional air filters have been installed that have been shown to capture and remove up to 95 percent of "Mycobacterium avium" aerosols. A 2004 st...

Anti cancer virotherapy well tolerated in first human administration, research finds

...d anti-cancer therapy based on the use of a common cold virus to control cancer cell growth has begun safety testing in human subjects. The research was presented to the third International Meeting on Replicating Oncolytic Virus Therapeutics, on Friday 11 March by Newcastle University associate professor...

Canada approves marijuana-based pain spray

... descriptions of neuropathic pain are of freezing, cold or burning sensations usually of the limbs and most often of the lower extremities.5 Many individuals with neuropathic pain respond inadequately to current treatment options.6,7 “It’s hard to explain to someone who has never felt this type of pain. ...

Anammox bacteria produce nitrogen gas in oceans' snackbar

...current system leads to upwelling of nutrient-rich cold water off the coast of Namibia and acts as a kind of snackbar in the tropical ocean, which is visited by many animals including giant whales. The newly discovered anammox bacteria remove ammonium from the ocean, which as a result can not be taken up ...

Turning viruses into allies against cancer

...virus, responsible for those lip blisters known as cold sores. In studies presented this week at the 96th meeting of the American Association for Cancer Research (AACR), researchers describe their latest studies with their engineered versions of these viruses. Cold Sore Virus Modified to Halt Growth and...

Elephant seal pups suffer from ocean warming

...y. "Despite ranging widely and foraging deeply in cold waters beyond coastal thermoclines in the northeastern Pacific, elephant seals are impacted significantly by ocean thermal dynamics", conclude the authors. Le Boeuf and Crocker add that monitoring the mean weaning weight of elephant seal pups can th...

Activation of thermoreceptors mediates raw garlic's burning pungency

...ili peppers, whereas TRPA1 is activated by noxious cold and by pungent compounds found in cinnamon oil, mustard oil, and wintergreen oil. These past findings, as well as the present work, indicate that thermosensitive TRP channels play a key role in the phenomenon of chemesthesis (the somatosensory contri...

Scripps scientists find potential for catastrophic shifts in Pacific ecosystems

...oaches. "The dynamics are the same during warm and cold periods, thus they are not true regimes," said Sugihara of the Physical Oceanography Research Division at Scripps. This is at least true for these data from the 20th century. "Finding nonlinearity is fundamental for understanding and managing change...

Currents could disrupt ocean food chain

...appened surprisingly fast. The climate went from a cold state to a warm state in as little as 20 to 50 years. Surface temperatures in Greenland increased 20 to 30 degrees Fahrenheit and water temperatures increased 10 to 20 degrees." Schmittner said the impact of the current on the Pacific Ocean generall...
