WALL-E, meet EVA: ‘Robo-doc’ navigates on its own, frees doctors to focus on the critically ill

Ronald Reagan UCLA Medical Center, the world’s first hospital to introduce a remote-presence robot into its neurological intensive-care unit in 2005, now welcomes the RP-VITA, the first robot able to navigate the hospital on its own.

UCLA staff affectionately dubbed the 5’5″, 176-pound robot “EVA,” for executive virtual attending physician. Unlike earlier models that physicians steered via a computer-linked joystick, this version drives on auto-pilot, freeing doctors to devote more time to patient care. (more…)

USGS Study Confirms U.S. Amphibian Populations Declining at Precipitous Rates

CORVALLIS, Ore. — The first-ever estimate of how fast frogs, toads and salamanders in the United States are disappearing from their habitats reveals they are vanishing at an alarming and rapid rate. (more…)

Cannibal Tadpoles Key to Understanding Digestive Evolution

A carnivorous, cannibalistic tadpole may play a role in understanding the evolution and development of digestive organs, according to research from North Carolina State University. These findings may also shed light on universal rules of organ development that could lead to better diagnosis and prevention of intestinal birth defects.

NC State developmental biologist Nanette Nascone-Yoder, graduate student Stephanie Bloom and postdoc Cris Ledon-Rettig looked at Xenopus laevis (African clawed frog) and Lepidobatrachus laevis (Budgett’s frog) tadpoles. These frog species differ in diet and last shared a common ancestor about 110 million years ago. Like most tadpoles, Xenopus exist primarily on a diet of algae, and their long, simple digestive tracts are not able to process insects or proteins until they become adult frogs. Budgett’s is an aggressive species of frog which is carnivorous – and cannibalistic – in the tadpole stage. (more…)

Easy come, easy grow

Sperm cell release can be triggered by tightening the grip around the delivery organ, according to a team of nano and microsystems engineers and plant biologists at the University of Montreal and Concordia University. Concordia’s nanobiotech team devised a microchip that enabled the University of Montreal biologists to observe what happened when pollen tubes – the sperm delivery tools used by plants – tried to negotiate a microscopic obstacle course. The pollen tubes were exposed to a series of narrow, elastic openings resulting in a variety of cellular responses. When the opening was too narrow or tight, pollen tube growth stalled. However, the elongating tubes successfully penetrated slightly larger openings. Curiously, the pollen tubes burst and released the sperm cells when passing openings of a particular size relative to the pollen tube width. (more…)

Century-Old Science Helps Confirm Global Warming

A new NASA and university analysis of ocean data collected more than 135 years ago by the crew of the HMS Challenger oceanographic expedition provides further confirmation that human activities have warmed our planet over the past century.

Researchers from the University of Tasmania, Sandy Bay, Australia; and NASA’s Jet Propulsion Laboratory, Pasadena, Calif., combined the ship’s measurements of ocean temperatures with modern observations from the international Argo array of ocean profiling floats. They used both as inputs to state-of-the-art climate models, to get a picture of how the world’s oceans have changed since the Challenger’s voyage. (more…)

Small, Speedy Plant-Eater Extends Knowledge of Dinosaur Ecosystems

Bethesda, MD — Dinosaurs are often thought of as large, fierce animals, but new research highlights a previously overlooked diversity of small dinosaurs. In the Journal of Vertebrate Paleontology, a team of paleontologists from the University of Toronto, Royal Ontario Museum, Cleveland Museum of Natural History and University of Calgary have described a new dinosaur, the smallest plant-eating dinosaur species known from Canada. Albertadromeus syntarsus was identified from a partial hind leg, and other skeletal elements, that indicate it was a speedy runner. Approximately 1.6 m (5 ft) long, it weighed about 16 kg (30 lbs), comparable to a large turkey. (more…)

Studying meteorites may reveal Mars’ secrets of life

In an effort to determine if conditions were ever right on Mars to sustain life, a team of scientists, including a Michigan State University professor, has examined a meteorite that formed on the red planet more than a billion years ago.

And although this team’s work is not specifically solving the mystery, it is laying the groundwork for future researchers to answer this age-old question. (more…)

PatternBuilders brings big data analytics down to size

Microsoft BizSpark startup makes next-generation big data analytics solutions accessible to enterprises of all sizes.

REDMOND, Wash. — May 23, 2013 — Data technology experts and startup veterans Terence Craig and Mary Ludloff founded PatternBuilders with a singular vision: to make it practical and easy for enterprises everywhere to harness big data and make better, faster decisions — without hiring a team of experts.

“We found it disconcerting that there was such a huge divide between big data excitement and actual adoption rates,” said Craig, CEO and chief technology officer at PatternBuilders. “Taking advantage of big data analytics often requires a budget, toolset and in-house expertise far beyond what most enterprises can muster. Mary and I founded PatternBuilders because we thought there must be a better approach.” (more…)
