UCLA scientists transform HIV into cancer-seeking missile

...raveled through the animal's bloodstream and homed straight to the cancer cells in the lungs, where the melanoma had migrated," said Chen. When the researchers held the mouse under the camera, the luciferase illuminated the cancer cells, which glowed through the animal's bones, muscles and fur. The method is...

Scientists journey to southern Africa to unravel the secret world of elephant communication

Stem cell research - new cell lines

... embryonic stem cells, so they can be transplanted straight into the affected area of a patient. "The insulin-producing cells, which are derived from the layer which also forms the gut and liver are the holy grail for diabetes researchers," said Dr Sidhu. "That's because they are destroyed in type-1 diabetes...

How monarch butterflies are wired for navigation

...nlight as a celestial guide to help them keep to a straight and true path southward. But details of their navigational machinery have remained a mystery. Now, researchers, led by Steven Reppert of University of Massachusetts Medical School, Ivo Sauman of the Czech Academy of Sciences and Adriana Briscoe of t...

The genetic origins of corn on the cob

...at suppressed branching in the ear, leading to the straight rows of kernels and the compact ears of modern-day corn on the cob. The findings are described in the July 24 advance online edition of the journal Nature. "We've shown that corn and related grasses have either none, some, or a lot of ramosa1 gene a...

Locusts' built-in 'surface analysis' ability directs them to fly overland

...ion of Aqaba and other areas of Jordan, as well as straight north over southern Israel. This observation led to examination by scientists of the Hebrew University of Jerusalem Department of Evolution, Systematics and Ecology and the Interuniversity Institute for Marine Sciences in Eilat to examine how the lo...

New results validating Pall prion reduction filter disclosed at ISBT Congress

...tion of the filter; handling of the system is very straight forward and we are planning clinical studies in the coming months." Dr. Roger Eglin, Head of the National Transfusion Microbiology Laboratory of the NBS, discussed the incidence and risk of vCJD transmission by blood transfusion. He reviewed the rol...

Bacteria which sense the Earth's magnetic field

... the magnetosome crystals have to be strung into a straight chain inside the cell, thereby summing their magnetic moments. Only such a chain structure allows the magnetosomes to behave together like a compass needle which orients the bacteria inside the relatively weak magnetic field of the Earth. But until n...

Bats use touch receptors on wings to fly, catch prey, study finds

...The bats appeared to fly normally when following a straight path, but when they'd try to take a sharp turn, such as at the corner of a room, they would drop or even jump in altitude, sometimes erratically. When the hairs grew back, the bats resumed making turns normally. "It was obvious they had trouble main...

Sensors, a smart dose of medicine for cancer treatment

...e wait. "Unlike most projects, this device will go straight to market and our commercial partner, ScandiDos in Uppsala, Sweden, is a start-up created for the manufacture and marketing of the device." Jaksic is particularly pleased because the new sensor systems will improve treatment verification for a large...

Feeling old?

This is the finding of research performed by Lydie Combaret, Dominique Dardevet and colleagues at the Human Nutrition Research Centre of Auvergne, INRA, Clermont-Ferrand, France. After the age of 40, humans start loosing muscle at around 0.5?...

Alleged 40,000-year-old human footprints in Mexico much, much older than thought

...ered all over, with no more than two or three in a straight line," which would be expected if someone had walked through the ash, Renne said. If the depressions were footprints, they could not have been made by modern humans, he noted, since even in Africa, Homo sapiens did not appear until about 160,000 year...

Largest study of human 'interactome' reveals a novel way

...proteins gave us the information to set the record straight on how to measure a protein's importance," he says. Using this kind of comprehensive comparison of information about human and other organisms allowed Pandey's group to identify 36 previously unknown protein-protein interactions, nine of which were ...

Scientist uses dragonflies to better understand flight

...d Wang. "Of all these paths, are any better than a straight line? Some are -- that's what I found." The insight came from dragonflies. "Dragonflies have a very odd stroke. It's an up-and-down stroke instead of a back-and-forth stroke," she said. "Dragonflies are one of the most maneuverable insects, so if t...

Movement of chromosome in nucleus visualized

...aid, because the chromosome was moving in a nearly straight line perpendicular to the nuclear envelope. The chromosome traveled further in several minutes than ever observed, even over several hours, in the absence of activation. "It looked nothing like the random, but localized, bouncing around that had bee...

Even fish don't swim well when they're young!

...ower forward in a 'burst' and then hold their body straight to 'coast'. Dr Müller and her colleagues might have found what it is that prevents larvae of the zebrafish from reaching top speeds: the larvae cannot maintain their body in a horizontal position while coasting. The research team think this is becaus...
