Boston University biologists discover amphibian eggs use defenses against water molds

...s are carried out either by the adult females when laying eggs or by the developing embryos themselves. Spotted salamanders wrap their eggs in a protective jelly layer that prevents mold from reaching the embryos. Wood frog egg clusters have less jelly, but are laid while ponds are still cold and mold gro...

Mars mission Risk 29: Scientists research ways to reduce radiation-induced brain damage

...put a man on Mars, NASA has sketched out a roadmap laying out 45 risks to astronauts in a space mission that is likely to last two years. Those risks include accelerated bone loss, motion sickness, the inability to treat minor illnesses, an inadequate quantity of food and the possibility of "interpersonal t...

Cellular traffic backups implicated in skeletal malformations

...oteins like collagen into the extracellular space, laying down a rigid matrix (the extracellular matrix or ECM) that will form cartilage. Under a microscope, type II collagen can mainly be found in the extracellular space. Only small amounts can be seen in the cytoplasm. In the crusher fish, Knapik an...

NIH launches Knockout Mouse Project

...launch of the Knockout Mouse Project, NIH has been laying the foundation for several years. In the fall of 2003, NIH co-sponsored an international meeting that concluded that the time was right for a coordinated effort to produce knockouts in every mouse gene, and a commentary calling for such a project was...

Sturgeon's general warning: stable for now, but beware

...n said. "This means that either the females aren't laying eggs or that they aren't spawning at all - both of which would have serious ramifications." Another possibility, he said, is that the researchers' sampling may not have been in the right place and most of the young were somewhere else. "This is a...

Study aims to identify schizophrenics at risk for type 2 diabetes

...y," says Dr. Kirkpatrick of the complex process of laying down normal communication pathways that apparently goes awry in about 1 percent of people. "It's kind of a subtle going wrong in the sense that if you look at the brain under a microscope, at first blush, it looks pretty normal, and on MRI (magneti...

When it counts: Shortening imaging time for individuals with suspected heart problems

...d Basso. "It may allow patients who can't tolerate laying still for 15 to 25 minutes to be scanned in half the time, and it provides the opportunity for smaller or community hospitals that have only a single-head camera to be as efficient as those that have dual-head cameras," he explained. The researchers ...

The urban evolution lab

...ding several weeks earlier than country birds, and laying larger clutches. And here's the trap: the nuts and other plant foods that fatten the parents are unsuitable for nestlings, which need the more digestible protein provided by insect larvae that will not emerge until later in spring. As a result, subur...

Alaska seal pup diet may hold key to decline of population

...Herring have a higher fat content in winter before laying their eggs, but lose about one-third of their fat after releasing their eggs.) Except for the fat content of the herring, the nutrient content was the same for both groups, Polasek explained. The researchers monitored the animals in the low fat group...

A new way of looking at molecular motors

All complex organisms use myosin and its relatives, kinesin and...

Molecule does more than slice and dice RNA

...oles in maintaining cells, rearranging genomes and laying down the architecture of the brain, for example. In the lab, Dicer is used in mice to switch off any combination of genes -- either in targeted or in random fashion -- to infer a gene's function, a capability that may be especially useful in understa...

UF scientists say stem cells may trigger bone cancer

The studies are laying the foundation for novel ideas about cancer and its development, and are opening new avenues of research that could someday lead to more effective treatments that target the mutant cells that grow into tumors. The cancer stem cell theory holds that ...

Ranks of 'environmental refugees' swell, calls grow for better definition, recognition, support

Rhythm gene discovered

...rhythmic events in a worm's life: swallowing food, laying eggs and pooping. If the gene is disabled, the worms can't swallow, so they die. If the gene is partly restored so the worms can swallow, they have trouble reproducing and get constipated. "We have found a gene that is important for the cont...

Researchers to gain wider access to knockout mice

Under terms of three-year contracts jointly funded by 19 NIH institutes, centers and offices, Deltagen Inc. of San Carlos, Calif., and Lexicon Genetics Incorporated of The Woodlands,...

Fish in ponds benefit flowering plants

...Likewise, there is evidence that dragonflies avoid laying eggs in ponds with fish. Knight noted that many organisms, for instance, salamanders, with terrestrial life stages also are key aquatic predators, so the reverse a cascade from terrestrial to aquatic ecosystem also is true. "This finding will ope...
