Baby fish 'smell their way home'

...salmon can smell the home river. "We know these late stage fish larvae, generally between about 9 and 14mm long, already have developed noses ?but the question was whether they could use them to recognise what the home reef smelt like, when they left it only a day or so after hatching." The team exp...

A revolution in the monitoring of unborn babies

...hey are running into difficulties before it is too late to help them. This may involve urgent delivery of the fetus.? The device will be especially helpful in monitoring fetuses whose mothers have medical conditions like diabetes, autoimmune conditions such as systemic lupus erythematosus and Sjogren’s ...

Genomics throws species definition in question for microbes

How fish conquered the ocean

... that showed an unprecedented radiation during the late Cretaceous and early Paleogene Periods. The work is a unique hypothesis that integrates the cellular and molecular physiology of teleost reproduction with their evolutionary and environmental history. "The oceans have not always been filled with fis...

CSIRO imagery shows Outer Great Barrier Reef at risk from river plumes

...e result of heavy rainfalls in northern QLD around late January to early February 2007, with the resulting flood waters carrying a larger sediment load than during regular rainfall and river flow. As such floods have not occurred for a while the accumulated material in the creeks ands rivers coupled with ...

Overfishing large sharks impacts entire marine ecosystem, shrinks shellfish supply

...n sampled bay scallops in North Carolina sounds in late summer before and after the cownose rays passed through, he found that most scallops survived the ray predation, allowing the scallop population to support a fishery and still replenish itself each year. In contrast, sampling by Peterson and co-autho...

U of MN researchers turn cord blood into lung cells

...rnal Cytotherapy. Type II alveolar cells develop late in fetal development, which is why some premature babies are born with underdeveloped lungs. The cells and the air sacs as a whole continue to mature and develop through a child's first few years of life. Now the researchers will try to better ch...

NASA snow data helps maintain nation's largest, oldest bison herd

"But this is a great opportunity to use NASA technology to help the folks at Yellowstone. This project lets them know what capabilities we have...

By 2048 all current fish, seafood species projected to collapse

...l flooding. "The good news is that it is not too late to turn things around," Worm said. The scientists studied 48 areas worldwide that have been protected to improve marine biodiversity. "We see that diversity of species recovered dramatically, and with it the ecosystem's productivity and stability." ...

Antibiotic inhibits cancer gene activity

...r approved. Gartel said the participation of the late Robert Costa, professor of biochemistry and molecular genetics at UIC and a leader in research on FoxM1, was critical for the success of the project thus far. Senthil Radhakrishnan, a visiting bioinformatics expert at UIC, is first author of the pa...

Proteins may predict lung transplant rejection

...gns of chronic rejection appear, it is usually too late to reverse it, she said. If doctors can predict which patients are beginning to reject the transplanted organ, they could try to head it off, she said. The study, "Proteomic biomarkers of chronic lung allograft rejection," was carried out by Wendt...

Salmon farms kill wild fish, study shows

... the sea lice population was low to 95 per cent in late spring when the sea lice population was higher. "Everyone knows that only a small fraction of juvenile salmon survive to return as adults," said Lewis. "The fish-farm sea lice are reducing that fraction even more." The research was conducted by a...

Evolution of Old World fruit flies on three continents mirrors climate change

...ly introduced to the Pacific Coast of Chile in the late 1970s and to the North American West Coast in the early 1980s, probably on cargo ships. They spread rapidly, and in North America they are now found from near Santa Barbara, Calif., to northern Vancouver Island in British Columbia. The first sampl...

New way of tracking muscle damage from radiation

...ict which patients need an intervention to prevent late damage," Krasin said. Soft tissue sarcomas are cancers that arise in muscles, fat, blood vessels and other soft tissues. Ewing sarcoma is a cancer that arises in the bone or soft tissue, usually in the arms, legs, pelvis or chest wall. St. Jude ...

NASA satellite data helps assess the health of Florida's coral reef

...when waters reach their warmest levels, usually in late summer and early fall. Phenomena like El Niño have also been linked to declines in reef health. During the strong El Niño of 1998, about 30 percent of coral off the Florida Keys died after a single mass bleaching. Other factors that influence the h...

Molecules in blood foretell development of preeclampsia

...ent of all pregnancies. When preeclampsia occurs late in a pregnancy, the baby can be delivered with relatively few ill effects. However, if preeclampsia occurs early in pregnancy, delivery of the baby would result in premature birth, which increases the risk of death, and for such lifelong complicatio...
