Psychologist finds instance where 'two wrongs do make a right'
...n. The theory holds that information from the eyes separates into two distinct streams: one to simply represent where we see things in the environment, and another to guide the physical movements of our body within that environment. Both processes have been thought to depend largely on accessing distinct maps ...Researchers discover defense mechanisms in some plants believed bred out by humans
...e. Using a procedure called gel filtration that separates proteins according to size, the researchers then found that the cause of aggregation was another protein, the beta-glucosidase aggregating factor (BGAF), which NULL lines produced in excess. They isolated BGAF and proved its aggregating activity. ...Researchers discover direct link between agricultural runoff and massive algal blooms in the sea
...w, 700-mile-long stretch of the Pacific Ocean that separates the Mexican mainland from the Baja California Peninsula. Immortalized in the 1941 book Sea of Cortez, by writer John Steinbeck and marine biologist Edward Ricketts, the region remains a hotspot of marine biodiversity and one of Mexico's most importan...Scientists discover unique microbe in California's largest lake
... jumped across the vast evolutionary distance that separates the proteobacteria and cyanobacteria, and switched places with the portion of the gene that had originally been inherited from the cyanobacterial parent. "This finding shows that even this popular evolutionary chronometer can be a mosaic of genetic i...Purdue proves concept of using nano-materials for drug discovery
...anic porous membrane - in this case alumina, which separates the reaction chamber from a solution. The pores in this membrane are nanometer in scale, so they do not allow proteins to readily pass through the membrane but will allow smaller molecules to pass. "This allows us to do separation right in the reacto...One year after groundbreaking, desert research center takes shape on the Israeli-Jordanian border
...acility in Israel and half in Jordan. A wire fence separates the border from the Dead Sea to the Red Sea, but in February, Israel and Jordan agreed to take down the barrier at the project site so that construction could move forward. When fully operational, the research center will have three laboratory buildi...'Hobbit' fossil likely represents new branch on human family tree
...he back of modern human brains. "The lunate sulcus separates the primary visual cortex from the rest of the brain," Hildebolt explains. "It tends to get pushed toward the back of the brain as the occipital, parietal, and temporal lobes expand, so normally it's a sign of advanced brain development." The findin...Oceans more vulnerable to agricultural runoff than previously thought, study finds
...w, 700-mile-long stretch of the Pacific Ocean that separates the Mexican mainland from the Baja California Peninsula. The area is a hotspot of marine biodiversity and one of Mexico's most important commercial fishing centers. "Biological productivity in most of the world's oceans is controlled by the supply of...Mice with defective sperm offer clues to infertility in men
...nulus has been thought to act as a gatekeeper that separates two areas of the sperm tail. Studying sperm from mice lacking Septin 4 allows us to finally ask if this is really the case, and the findings will advance our understanding of how sperm become cells capable of fertilization." Research on the roles of...Counting cells in blood samples may predict cancer treatment's effectiveness
...ls through flow cytometry, an analysis method that separates cells by energy, and by stains that attract to specific types of cells. Researchers found that patients with low circulating endothelial cell counts, defined as fewer than 15 per sample of blood, remained on the therapy longer than people who had mor...Rice, Iowa state biologists search for 'half-fusion'
...l is surrounded by a membrane, a thin barrier that separates the genetic machinery of life from the non-living world outside. Though barriers, membranes are not impervious. Cells use a complex hierarchy of proteins that work in concert to allow cell membranes to fuse with other cells or with membrane-encased ...Device creates electricity and treats wastewater
...nductive wire. In a hydrogen fuel cell a membrane separates the anode and cathode chambers. When hydrogen meets the anode electrode, it splits into protons and electrons, with protons going across the membrane to the cathode chamber, and electrons passing over the wire between electrodes to create a current....Fluorescing lab worms signal longer life spans, reports CU-Boulder team
...evels in the nematodes and a pneumatic device that separates them into groups with short pulses of air was used during the study. One of only six such instruments in the United States, the machine can sort about 30 worms per second, Johnson said. Genetic testing on both the bright and dim worms revealed that...Gold bowties may shed light on molecules and other nano-sized objects
...light and squeezes it into a 20-nanometer gap that separates the two gold triangles. The result is a concentrated speck of light that is a thousand times more intense than the incoming near-infrared beam.

...atic hernia (CDH), or a hole in the diaphragm that separates the lungs from the visceral organs. If the hole is large enough, the stomach and other visceral organs can end up in the chest cavity, crowding the lungs and stunting their growth.

... cases, an additional procedure called "pinch-off" separates candidates that aren't actually connected and discards those that are. Boxes are drawn around the final picks and their image quality is enhanced by an operation called "shrink-wrapping." If a portion of an adjacent particle protrudes into the box, ...Learned motor programs directly influence the visual perception of movements
... this week, researchers present an experiment that separates the influences of visual and motor learning during the acquisition of a new motor behavior and demonstrate that motor learning imparts a direct influence on visual perception, independently of visual familiarity with learned movements. The findings a......"A long generation time is an important trait that separates humans from their evolutionary relatives," said Navin Elango, graduate student in the School of Biology and first author of the research paper. "We used to think that apes shared one generation time, but that's not true. There's a lot more variation....
