Computer rendering: Graduate student brings extinct plants 'back to life'

Posted: 11 Apr 2014 12:38 PM PDT

Most fossilized plants are fragments indistinguishable from a stick, but a graduate student hopes a new technique will allow paleontologists to more precisely identify these fossils. A graduate student showed the power of this technique by turning a 375 million-year-old lycopod fossil into a life-like rendering.

How nerve cells flexibly adapt to acoustic signals

Posted: 11 Apr 2014 07:31 AM PDT

Nerve cells flexibly adapt to acoustic signals, research has shown. Depending on the input signal, neurons generate action potentials either near or far away from the cell body. Nerve cells ensure that the various kinds of input signals are optimally processed -- and thus allow us to perceive both small and large acoustic arrival time differences well, and thereby localize sounds in space.

Eye of the beholder: Improving the human-robot connection

Researchers are programming robots to communicate with people using human-like body language and cues, an important step toward bringing robots into homes.

Appearance of night-shining clouds has increased

Posted: 11 Apr 2014 06:19 AM PDT

First spotted in 1885, silvery blue clouds sometimes hover in the night sky near the poles, appearing to give off their own glowing light. Known as noctilucent clouds, this phenomenon began to be sighted at lower and lower latitudes -- between the 40th and 50th parallel -- during the 20th century, causing scientists to wonder if the region these clouds inhabit had indeed changed -- information that would tie in with understanding the weather and climate of all Earth.

Scientists grow cartilage to reconstruct nose

Posted: 10 Apr 2014 04:46 PM PDT

Scientists report first ever successful nose reconstruction surgery using cartilage grown in the laboratory. Cartilage cells were extracted from the patient's nasal septum, multiplied and expanded onto a collagen membrane. The so-called engineered cartilage was then shaped according to the defect and implanted.

Sneak a peek through the mist to technology of the future

A tabletop display with personal screens made from a curtain of mist that allow users to move images around and push through the fog-screens and onto the display, will be unveiled at an international conference.

Laboratory-grown vaginas implanted in patients

Scientists reported the first human recipients of laboratory-grown vaginal organs. They have described long-term success in four teenage girls who received vaginal organs that were engineered with their own cells.
