Breakthrough developments in rheumatoid arthritis reported
...ling inflammatory condition. Dr. Gregersen has finally closed the circle between key genes identified in his laboratory at the Robert S. Boas Center for Genomics and Human Genetics at The Feinstein Institute for Medical Research in Manhasset, NY and more than a 1,000 patients with rheumatoid arthritis. T...Massive herds of animals found to still exist in Southern Sudan
...tor of the WCS Southern Sudan Country Program, did finally sight a group of three zebra moving with the white-eared kob migration in Boma National Park. The team also identified a key zone of semi-arid habitat supporting several species, which will be proposed as a new protected area. (OVER) In an effort...'Wurst' ensures that the respiratory system works
...t of a system of tubes that branch out like trees, finally ending in the air cells called alveoli. This is where the inhaled oxygen enters the blood." Analogies have also been discovered in the way the two respiratory systems develop. Thus, a series of very similar growth factors ensure that the tubes branch...Banding together: RAS signaling of circadian output
... with colleagues at Dartmouth Medical School, have finally cloned the band gene, and have found that it is an allele of ras-1. This finding posits RAS signaling as a key mediator of circadian output. The fungus Neurospora crassa is one of the best studied laboratory systems for circadian rhythms. However, ...TU Delft tracks the influence of a cancer inhibitor on a single DNA molecule
...NA strands, after which it allows it to unwind and finally joins the broken ends together. Until now it has been supposed that topotecan only causes the TopoIB protein to reside longer than normal on the DNA molecule, disturbing the cell division and damaging the (cancer) cell. But the Delft researchers ha...Translating form into function
... researchers show that a solution to the puzzle is finally in sight. A team co-led by UCSFs Brian Shoichet, Steven Almo of the Albert Einstein College of Medicine, and Frank Raushel of Texas A&M describes the first success decrypting an enzymes function from its structure. If their new strategy works with o...Rapid evolution of defense genes in plants may produce hybrid incompatibility
...ely, but not with members of other species. What finally establishes two populations as different species is that gene flow between them stops. However, this does not happen suddenly. Rather, it is a gradual process in which one barrier after another is raised between two species, including inviable emb...The origin of perennial water-ice at the South Pole of Mars
...eposits and the mechanism of their formation could finally be suggested. This was achieved thanks to the OMEGA mapping and characterisation of these ice deposits, combined with the computer-generated Martian Global Climate Models (GCMs). The mapping and spectral analysis by OMEGA has shown that the peren......cuum tubes and wires" Next came the transistor and finally the silicon chip, which dramatically revolutionized computers and modern electronics. Microfluidics is following the track of silicon chips and promises to revolutionize biology in the same manner. The microfluidic chip designed by Quake and his col...American Chemical Society's Weekly PressPac -- July 18, 2007

In doing so, the researchers say, the droplet demonstrated a primitive form of chemotaxis, one of the most basic cellular responses in which the cell directs its movement toward the presence of certain chemicals in its environment. ...Presence of wolves allows aspen recovery in Yellowstone

Such reactions are energetically intensive, requiring the input of adenosine triphosphate (ATP) a cellular fuel source.

...ive first, followed by the gamma-globin genes, and finally the adult form, beta-globin takes control following birth. Understanding how genes are regulated or turned on and off is critical. In gene therapy, a normal gene can be inserted into cells to correct a genetic defect. However, according to Lloyd, i...Gene variant is associated with brain anatomy, clinical course of ADHD

Analyses of the children who participated in the follow-up revealed that the differences between the brain anatomy of those with and without the DRD4 7-repeat allele were most pronounced in early developm...European Science Foundation's Forward Look reaches out beyond the endless frontiers
