Computational analysis shows that plant hormones often go it alone

...of the data ourselves, we had to perform extensive quality controls to extract meaningful information," explains Hong. The Salk researchers' analysis revealed that surprisingly few genes were switched on by multiple hormones. And when more than one hormone did initiate a similar program, such as activating...

Cultural transmission in bats: When listening for dinner, bats learn from their neighbors

...ated that bats that use frog acoustic cues to find quality prey can rapidly learn these cues by observing other bats. While numerous examples are known of instances where predators can use so-called "social learning" to learn new visual and olfactory cues associated with prey, this kind of learning of an aco...

New egg freezing technique offers hope to hundreds of women

...umbers involved). Dr Chamayou also found that the quality of embryos differed significantly depending on whether fresh or frozen eggs had been used; out of the total number of embryos, 36.7% were grade 1 embryos after IVF using fresh eggs, 19.5% were grade 1 after ICSI using fresh eggs (giving an overall pe...

New study reveals components of cocoa may enhance the appearance of the skin

...ding to see that these benefits may extend to skin quality as well." In addition to the improvements in skin quality in study participants, this study is the first to suggest that the regular consumption of cocoa flav...

Nutrition a major factor in rise in twin pregnancies

...ons, it could prove difficult to reverse as embryo quality continues to improve ?whether in the IVF lab or in the community generally." "Because two implanted embryos have twice the chance of MZ twins than a single implanting embryo the best way of minimising MZ as well as DZ twinning is to transfer one emb...

DOE JGI finishes 100th microbial genome

... the sequencing process, in order to meet rigorous quality standards and to satisfy the demands of the scientific community, is an iterative one, requiring six- to eight-times coverage. The term "finished," associated with the 100 microbial genomes accomplished by DOE JGI, is a technical designation referri...

In-home sensors spot dementia signs in elderly

...dependence represents a significant improvement in quality of life of many elders who like to remain as long as possible in their familiar environments," Pavel noted. The ability to continuously and discretely collect activity data over extended periods of time has given researchers a new, more accurate wa...

Honey helps problem wounds

...ihoney bears the CE seal for medical products; its quality is regularly tested. The success is astonishing: 'Dead tissue is rejected faster, and the wounds heals more rapidly,' Kai Sofka, wound specialist at the University Children's Clinic, emphasises. 'What is more, changing dressings is less painful, sinc...

Malignant melanoma cells secrete protein required for embryo formation

... via epigenetic (other than genetic) mechanisms, a quality known as bi-directional cellular communication. Bi-directional cellular communication is integral to both cancer progression and embryological development. The significance of the research team's finding is profound in that it implies that through...

Iraq's marshes show progress toward recovery

...h has kept salinity levels low. The incoming water quality has been better than predicted, too, with toxin levels lower than had been feared. As a result, many native species have returned, including some rare bird species, although their numbers have not rebounded to historical levels. Iraq's marshes were ...

Johns Hopkins lab scientists tame overactive CF protein

... the defective CFTR to successfully sneak past the quality control and race up to the surface." To determine VCP's role in the destruction of CFTR, researchers compared bronchial cells from CF and non-CF patients. In non-CF cells, the protein's levels were in check, whereas they were strikingly high in cell...

Northern birds are fatter!

"Our data can be used to assess habitat quality and the importance of specific sites for migratory birds, and this can contribute to decisions about whether migratory sites are protected and which sites are prioritised for protection", explains Williams. Two techniques were used to study Western...

Plastic surgeons countdown first full facial transplantation

MIT researchers build tiny batteries with viruses

... important, too, because energy density is a vital quality in batteries. A lack of energy density - meaning the amount of charge a battery of a given size can usefully carry - is what has hampered development of electric cars, since existing batteries are generally too heavy and too weak to compete with gaso...
