Scientists enlist big data to guide conservation efforts

July 18, 2014 12:37 pm | by Robert Sanders, UC Berkeley | News | Comments

“Big data” has yet to make a mark on conservation efforts to preserve the planet’s biodiversity. But that may soon change with a new model developed by Univ. of California, Berkeley, biologist Brent Mishler and his colleagues in Australia. This effort  leverages the growing mass of data to take into account not only the number of species throughout an area, but also the variation among species and their geographic rarity, or endemism.

Blind lead the way in brave new world of tactile technology

July 2, 2014 9:46 am | by Yasmin Anwar, UC Berkeley | News | Comments

New research at UC Berkeley has found that people are better and faster at navigating tactile technology when using both hands and several fingers. Moreover, blind people in the study outmaneuvered their sighted counterparts, perhaps because they’ve developed superior cognitive strategies for finding their way around. These insights are useful as more media companies are implementing tactile interfaces.

Young researcher discovers source of disco clams’ light show

June 25, 2014 11:27 am | by Robert Sanders, UC Berkeley | Videos | Comments

Using high speed video, transmission electron microscopy, spectrometry, energy dispersive x-ray spectroscopy, and computer modeling, a Univ. of California, Berkeley graduate student has unraveled the mystery of the disco clams flashing “lips”. Most people assumed the glowing mantle was the result of bio-luminescence, but Lindsey Dougherty has found it is caused by something else entirely.

Dynamic spectroscopy duo

June 17, 2014 1:34 pm | by Lynn Yarris, Lawrence Berkeley National Laboratory | News | Comments

From allowing our eyes to see, to enabling green plants to harvest energy from the sun, photochemical reactions are ubiquitous and critical to nature. Photochemical reactions also play essential roles in high technology. Using photochemical reactions to our best advantage requires a deep understanding of the interplay between the electrons and atomic nuclei within a molecular system after that system has been excited by light.

New clues to why older women are more vulnerable to breast cancer

June 6, 2014 10:56 am | by Dan Krotz, Lawrence Berkeley National Laboratory | News | Comments

Scientists from Lawrence Berkeley National Laboratory have gained more insights into why older women are more susceptible to breast cancer. They found that as women age, the cells responsible for maintaining healthy breast tissue stop responding to their immediate surroundings, including mechanical cues that should prompt them to suppress nearby tumors.

New laser sensing technology could support self-driving cars, smartphone tech

May 29, 2014 11:50 am | News | Comments

A new twist on 3-D imaging technology could one day enable your self-driving car to spot a child in the street half a block away or play “virtual tennis” on your driveway. The new system, developed by researchers at the Univ. of California, Berkeley, can remotely sense objects across distances as long as 30 feet, 10 times farther than what could be done with comparable current low-power laser systems.

May 23, 2014 8:08 am | by Lynn Yarris, Lawrence Berkeley National Laboratory | News | Comments

A pathway to the design of even more effective versions of the powerful anticancer drug Taxol has been opened with the most detailed look ever at the assembly and disassembly of microtubules, tiny fibers of tubulin protein that form the cytoskeletons of living cells and play a crucial role in mitosis.

Metal-organic framework shows new talent

May 21, 2014 8:15 am | News | Comments

This gift from science just keeps on giving. Measurements taken at NIST show why a material already known to be good at separating components of natural gas also can do something trickier: help convert one chemical to another, a process called catalysis. The discovery is a rare example of a laboratory-made material easily performing a task that biology usually requires a complex series of steps to accomplish.

Lighting the way to graphene-based devices

May 16, 2014 1:45 pm | by Lynn Yarris, Lawrence Berkeley National Laboratory | News | Comments

Graphene continues to reign as the next potential superstar material for the electronics industry, a slimmer, stronger and much faster electron conductor than silicon. With no natural energy bandgap, however, graphene’s superfast conductance can’t be switched off, a serious drawback for transistors and other electronic devices.

Astronomers spot most Earth-like planet yet

April 17, 2014 2:56 pm | by Alicia Chang, AP Science Writer | News | Comments

Detected by NASA's orbiting Kepler telescope, a newly found planet is the most Earth-like planet yet detected. Astronomers say the distant, rocky world is similar in size to our own and exists in the Goldilocks zone where it's not too hot and not too cold for life. The find, announced Thursday, excited planet hunters who have been scouring the Milky Way galaxy for years for potentially habitable places outside our solar system.

New semiconductor holds promise for 2-D physics, electronics

March 21, 2014 7:54 am | by Lynn Yarris, Lawrence Berkeley National Laboratory | News | Comments

From super-lubricants, to solar cells, to the fledgling technology of valleytronics, there is much to be excited about with the discovery of a unique new 2-D semiconductor, rhenium disulfide, by researchers at Lawrence Berkeley National Laboratory’s Molecular Foundry. Rhenium disulfide, unlike molybdenum disulfide and other dichalcogenides, behaves electronically as if it were a 2-D monolayer even as a 3-D bulk material.

Making sense of big data

March 13, 2014 12:56 pm | by Wallace Ravven, UC Berkeley | News | Comments

Ben Recht, a statistician and electrical engineer at the Univ. of California, Berkeley, looks for problems. He develops mathematical strategies to help researchers, from urban planners to online retailers, cut through blizzards of data to find what they’re after. He resists the “needle in the haystack” metaphor for big data because, he says, people usually don’t know enough about their data to understand the goal.

March 12, 2014 8:08 am | by Sarah Yang, Media Relations, UC Berkeley | Videos | Comments

Sometimes it only takes a quick jolt of electricity to get a swarm of cells moving in the right direction. Researchers at the Univ. of California, Berkeley found that an electrical current can be used to orchestrate the flow of a group of cells, an achievement that could establish the basis for more controlled forms of tissue engineering.
