Advancements in Computer Vision for Security and Realism

Widespread crime and the rise of global terrorism have meant that security systems need to incorporate sophisticated and rapid computer recognition of human faces, as delegates will hear next week at the British Machine Vision Conference being held at the University of East Anglia (UEA).

Another side of the same coin is in making human faces that appear on computers as convincing as possible, and in particular making speech appear realistic, as a team of UEA researchers will tell the confere

New Algorithm Accelerates X-Ray Crystal Structure Analysis

Identifying the structures of certain types of molecular compounds can now take minutes, instead of days, and be performed much more accurately, say scientists who developed a new approach for analyzing key experimental X-ray data.

Knowing the structure of a molecule allows scientists to predict its properties and behavior. While X-ray diffraction measurements have become a powerful tool for determining molecular structure, identifying the three-dimensional structure that best fits the diff

Unique Deep-Sea Nursery Discovered Off Northern California

Exploring a deep-sea ridge off Northern California, scientists at the Monterey Bay Aquarium Research Institute (MBARI) have discovered a unique undersea nursery, where groups of fish and octopus brood their eggs, like chickens on their nests. This is the first time that marine biologists have directly observed any deep-sea fish brooding its eggs. It is also the first time that two different types of mobile deep-sea animals have been observed brooding together in the same area. Although the scientists

First Pheromone Receptor in Fruit Flies Linked to Mating Behavior

For the first time in any animal, Duke University Medical Center researchers have linked a single pheromone receptor in the fruit fly to a specific sexual behavior.

Pheromones are chemical signals exuded by many animals — including humans — that serve as stimuli to evoke behavioral responses in other individuals of the same species. Pheromones often attract members of the opposite sex and provide important cues during courtship and mating.

Yet little is known about pheromone re

Targeting Transcription: New Insights on Gene Activation

The 35,000 or so genes within a human cell are something like players on a sports team: If their activity isn’t controlled and coordinated, the result can be disastrous.

So just as coaches tell individual players when to scramble onto the field and when to stay on the bench, molecules called transcription factors prompt particular genes to be active or stay quiet. Transcription factors occur naturally in cells, but researchers have been working to develop artificial transcriptio

New Gene Discovery Could Transform Spinal Cord Research

Discovery holds immediate promise for diagnosis & treatment of hereditary spastic paraplegia

A single mutation in a single gene is enough to slowly rob people of their ability to walk, scientists from the University of Michigan and the University of Pennsylvania report today.

And while the inherited defect itself is rare, its discovery may help researchers unravel the mysteries of much more common paralyzing conditions, from spinal cord injury to Lou Gehrig’s disease.

Scientist find more efficient way to "unlearn" fear

Could help improve treatment of anxiety

Behavior therapists may have a better way to help anxious patients, thanks to insights from a UCLA study of different ways to get mice past their fears. Rodents have long been used to study learning by association. Neuroscientists compared different ways of exposing mice to a stimulus that they had learned to fear, and found that “massing” the feared stimulus -– delivering it in concentrated bursts, not pacing it with longer pauses in between –
