Staphylococcus aureus hides out in cells

... immune system’s defences and dodge antibiotics by climbing into our cells and then lying low to avoid detection. New research in the online open access journal BMC Genomics shows how S. aureus makes itself at home in human lung cells for up to two weeks. A team of 12 researchers from University Hospital of ...

Lessons from the orangutans: Upright walking may have begun in the trees

...e other hand, became more specialized for vertical climbing between the high canopy and the ground and thus developed knuckle-walking for crossing from one tree to another on the ground. "Our conclusion is that arboreal bipedalism had very strong adaptive benefits. So, we don't need to explain how our ance...

Scientists discover new species of distinctive cloud-forest rodent

...losest relatives are spiny rats. The nocturnal, climbing rodent is beautiful yet strange looking, with long dense fur, a broad blocky head, and thickly furred tail. A blackish crest of fur on the crown, nape and shoulders add to its distinctive appearance. Isothrix barbarabrownae, as the new species has...

Protowings may have helped bird ancestors cover rough terrain

...ming the feathers, WAIR becomes less effective for climbing slopes. Dial and colleagues propose that incipiently feathered forelimbs of bipedal protobirds may have provided the same advantages for incline running as have now been demonstrated in living juvenile birds. Their work thus supports a new theory abo...

Spinal cord bridge bypasses injury to restore mobility

... right side limbs. The animals had trouble moving, climbing or grooming. Combining the old with the new, the researchers grafted a 1.5 centimeter piece of the tibial branch of he sciatic nerve to the C3 area of the spinal cord and allowed the nerve fibers to grow and regenerate over three weeks. .

This study included researchers at Bogor Agricultural University in Bogor, Indonesia, and the Southwest National ...

Wright bros. upstaged! Dinos invented biplanes

... is that gravity was the source of energy: a small climbing dinosaur first parachuted down, then began to stay aloft longer by gliding, and finally acquired powered flight. As those abilities developed, feathers became larger and more specialized, providing greater lift and thrust. The Chinese feathered din...

Gap-climbing fruit flies reveal components of goal-driven behaviors

Spider blood found in 20 million year old fossil

...es how the spider died. He believes the spider was climbing up a tree when it was struck head-on by a sudden strong flow of resin. The spider then became engulfed in the resin and died. He argues that the shape and position of the blood droplets reveals which direction the spider was travelling in. It also r...
