Releasing fish for the future

...und to massively boost fish survival. “Simply cutting the line rather than attempting to remove hooks swallowed by mulloway and yellowfin bream increased their survival from 12 percent to more than 85 percent. “Up to 76 percent of the released line-cut, gut-hooked yellowfin bream then shed their hook...

Pesticides choke pathway for nature to produce nitrogen for crops

...sity of Oregon. "In essence, the agrichemicals are cutting the lines of communication between the host plant and symbiotic bacteria. This is the mechanism by which these chemicals reduce symbiosis and nitrogen fixation." Fox began the project as a doctoral student with John A. McLachlan, director of the C...

Researchers examine carbon capture and storage to combat global warming

...tanford researchers are exploring another path for cutting emissions of carbon dioxide, the leading greenhouse gas that causes global warming. Carbon capture and storage, also called carbon sequestration, traps carbon dioxide after it is produced and injects it underground. The gas never enters the atmosphe...

Mutating the entire genome

...e gene. The protein made by Cre acts like a knife, cutting the DNA wherever loxP is found. The offspring mouse, in turn, is bred with a normal mouse. In a “remarkably high” average of 10 percent of the offspring, the desired large stretch of DNA is either deleted or duplicated so scientists can see what ...

AAAS decries latest stem cell veto

Anthrax paralyzes immune cells with lethal toxin, UF research shows

...eutrophils to move," said Southwick. "So it's like cutting the gas to the motor." Anthrax literally cuts the gas line. The toxin works like a pair of scissors, snipping off the ends of a key protein and preventing the transmission of messages within the cell. As a result, immune cells never receive the gr...

Study warns deep-sea mining may pose serious threat to fragile marine ecosystems

... from the active vents, but Halfar argues that the cutting and pumping process will disgorge considerable amounts of fine sediment into the water column—a serious problem for vent organisms that feed by filtering the water in their habitat. The process will also raise the concentrated nutrients from the ...

Bones in motion: Brown scientists to create new 3-D X-ray system

...ns and cartilage that surround them, would require cutting into flesh ?not a desirable option. The new system, dubbed CTX, will combine the 3-D capability of CT scanners and the real-time movement tracking of cinefluoroscopy. CTX technology is expected to deliver images with exceptional precision and deta...

Surgeons develop simpler way to cure atrial fibrillation

... III procedure, the lines of ablation were made by cutting the heart muscle, sewing the incisions back together and letting a scar form. The ablation lines redirect the abnormal electrical currents responsible for atrial fibrillation, an irregular heart rhythm in which the upper heart chambers or atria wrigg...

Dual gene therapy suppresses lung cancer in preclinical test

...r most powerful effect when administered together, cutting the number of tumors per mouse by 75 percent and the weight of tumors by 80 percent. "In cancer treatment we have combination chemotherapy, and we also combine different modes of therapy - surgery, radiation and chemotherapy. Now you've got the po...

No-scalpel vasectomies by skilled surgeons may speed recovery

...ure the skin. Advantages of puncturing rather than cutting the skin of the scrotum include less bleeding, bruising, infection and pain. Also, the puncture is usually so small that it does not require stitches. The review looked at two studies that compared the no-scalpel method of vasectomy to the tradit...

Sleep disturbances affect classroom performance
