UCLA Engineering Researchers Use Electricity to Generate Alternative Fuel

Science

Imagine being able to use electricity to power your car — even if it’s not an electric vehicle. Researchers at the UCLA Henry Samueli School of Engineering and Applied Science have for the first time demonstrated a method for converting carbon dioxide into liquid fuel isobutanol using electricity.

Today, electrical energy generated by various methods is still difficult to store efficiently. Chemical batteries, hydraulic pumping and water splitting suffer from low energy-density storage or incompatibility with current transportation infrastructure. (more…)

Jasmine Villegas and Internet Explorer Invite Fans to Be Part of New Interactive Music Video Experience

Technology

Fans take center stage and become part of the action in new HTML5 music video.

REDMOND, Wash. — Fans of recording artist Jasmine Villegas have a new way to immerse themselves in her music as they become part of the new video for her hit song, “Just a Friend.” Villegas (known simply as Jasmine) partnered with Internet Explorer and the interactive storytellers at Digital Kitchen to create a highly interactive music video that tailors the experience to each viewer, giving everyone the opportunity to influence the outcome of the storyline, see their own Facebook photos throughout the video and even “talk” to Jasmine herself.

Scientists Find Evidence That Human Ancestors Used Fire One Million Years Ago

Science

300,000 years earlier than believed

An international team led by the University of Toronto and Hebrew University has identified the earliest known evidence of the use of fire by human ancestors. Microscopic traces of wood ash, alongside animal bones and stone tools, were found in a layer dated to one million years ago at the Wonderwerk Cave in South Africa. (more…)

Social Media a Key Tool for People Entering Today’s Job Market

Economy, General, Technology

Many of today’s college students use social media as their main form of communication, but getting them to use it in a professional manner can sometimes be a challenge, according to Lisa Severy, director of the University of Colorado Boulder Office of Career Services.

With many employers using social media and conducting Google searches as part of their employee screening process, creating a positive and professional online presence can go a long way in helping students land a job out of school, according to Severy. (more…)

Rare Animal-Shaped Mounds Discovered in Peru by MU Anthropologist

Science

*Anthropology Helps Us Understand the Past and Allows for a Deeper Understanding of the Future.*

COLUMBIA, Mo. — For more than a century and a half, scientists and tourists have visited massive animal-shaped mounds, such as Serpent Mound in Ohio, created by the indigenous people of North America. But few animal effigy mounds had been found in South America until University of Missouri anthropology professor emeritus Robert Benfer identified numerous earthen animals rising above the coastal plains of Peru, a region already renowned for the Nazca lines, the ruined city of Chan Chan, and other cultural treasures.

“The mounds will draw tourists, one day,” Benfer said. “Some of them are more than 4,000 years old. Compare that to the effigy mounds of North America, which date to between 400 and 1200 AD. The oldest Peruvian mounds were being built at the same time as the pyramids in Egypt.” (more…)

Slow Snails, Fast Genes: Predatory Snails Refine Venoms Through Continuous Gene Duplication

Nature

ANN ARBOR, Mich.— When tropical marine cone snails sink their harpoon-like teeth into their prey, they inject paralyzing venoms made from a potent mix of more than 100 different neurotoxins.

Biologists have known for more than a decade that the genes which provide the recipes for cone snail toxins are among the fastest-evolving genes in the animal kingdom, enabling these predatory gastropods to constantly refine their venoms to more precisely target the neuromuscular systems of their prey.

Scientists Identify Novel Pathway for T Cell Activation in Leprosy

Science

*Findings may help lead to new treatments for infectious diseases, cancer*

UCLA researchers have pinpointed a new mechanism that potently activates T cells, the group of white blood cells that plays a major role in fighting infections.

The team specifically studied how dendritic cells, immune cells located at the site of an infection, become more specialized to fight the leprosy pathogen known as Mycobacterium leprae. Dendritic cells, like scouts in the field of a military operation, deliver key information about an invading pathogen that helps activate the T cells in launching a more effective attack. (more…)
