Computer with brain connections changing quality of life of paralyzed

...wn as 'Lou Gerhig's disease') are being challenged based on new research on brain-computer interaction. ALS is a progressive disease that destroys neurons affecting movement. The study appears in the latest issue of Psychophysiology. The article reviews the usefulness of currently available brain-computer ...

More species in the tropics because species have been there longer

...Americas. Combining analyses of evolutionary trees based on DNA sequences with GIS-based methods for analyzing the effects of climate on species distributions, the researchers found no relationship between how quickly species originate within a group and whether that group is tropical or temperate. How...

Record ozone loss during 2006 over South Pole

...ides operational ozone and UV radiation monitoring based on SCIAMACHY and GOME-1 data. The ozone-monitoring data provided by these instruments span a time period of 11 years, which will be extended by the upcoming MetOp satellite series. The first MetOp satellite in the series of three is scheduled to b...

Triple threat: World fin trade may harvest up to 73 million sharks per year

Underweight women at greater risk of miscarriage

...Obstetrics and Gynaecology. The study, from a team based at the London School of Hygiene & Tropical Medicine, aimed to examine the association between biological, behavioural and lifestyle risk factors and the risk of miscarriage, which affects an estimated quarter of a million women in the UK every ye...

Fight weeds with plant pathogens

... 12 percent (causing up to $32 billion in losses), based on the potential value of all U.S. crops of approximately $267 billion/year. Weeds also pose serious ecological problems. Invasive weeds are capable of altering ecosystem processes and displacing native plant and animal species. In addition, weeds se...

New findings could lead to vaccine for severe malaria

.... "This would mean that a future vaccine cannot be based on the principle of one protein-one receptor, as was previously believed." Now that scientists know that several placental receptors are involved in the binding mechanism, attention will be shifted to the parasite itself, and whether it produces man...

Two nerve cells in direct contact

...tial cells of the lobula plate in detail. This was based on a multitude of experiments in which the connections between the cells within one lobular plate and those between the two hemispheres were examined. In the end it turned out that there were two ways in which movement information from one half of th...

New brain-chemistry differences found in depressed women

... issue of the Archives of General Psychiatry. It's based on brain imaging, blood chemistry and other data from 14 women with major depression, and 14 healthy women of about the same age and background. The women with depression were not taking antidepressants when the study began. "This work gives furth...

Tarantula venom and chili peppers target same pain sensor

...istent pain, the scientists report. Their finding, based on studies of mice cells in culture and live mice, is published in the November 9 issue of the journal Nature. The senior author is David Julius, professor and chair of physiology at UCSF. The tarantula venom targets the heat sensor on nerve cells...

Transplanted photoreceptor precursor cells restore visual function in mice with retinal degeneration

...tored their visual function. The achievement is based on a novel technology in which the cells are introduced at a particular stage in their development. It was carried out at the London Institute of Ophthalmology using a novel approach developed at the University of Michigan Kellogg Eye Center to tag r...

Genome archaeology illuminates the genetic engineering debate

...g fixed in their position in the genome is largely based on studies in animal genomes. In contrast to those studies, however, the authors show that plant genomes evolved from a far more dynamic structure than previously believed. Maize dominates domestic agriculture, where approximately 9 billion bushels...

NYU biologists identify gene that coordinates two cellular processes

...s. Biologists can draw connections between genes based on systematically accumulated experimental evidence. Network diagrams that illustrate such connections show that most genes fall into highly interconnected groups called modules. These modules are often enriched for genes that share the same role. In...

However some communities of deep-sea corals associated with many seeps...

Studies find general mechanism of cellular aging

...hat any promise of a potential new aging treatment based on p16INK4a should include two important caveats. "First, even though old mice lacking p16INK4a show enhanced stem cell function, they do not live longer. This is because p16INK4a is an important cancer-suppressor gene, and mice lacking p16INK4a d...
