Environment takes big hit from water-intensive marijuana cultivation

Department of Integrative Biology - Wed, 06/24/2015 - 13:21

Published today in the journal Bioscience, the report outlines how illegal marijuana production is hitting California where it hurts, such as in sensitive watersheds already stressed by the state’s ongoing drought. Networks of pipes and hoses siphon water directly from small streams to irrigate the crops, draining what little water there is for wildlife and plants.

Cockroach Robot Squeezes Though Cracks (Ugh!)

Department of Integrative Biology - Tue, 06/23/2015 - 12:53

Dubbed “veloci-roach,” the crawling device uses sensors and locomotion like many other bio-inspired devices.

But this one flips on its side to shimmy through spaces that would normally prove too small, according to Chen Li, postdoctoral researcher in the UC Berkeley department of integrative biology, and electrical engineering and computer science.

Nielson Helps Identify 8,500-year-old Kennewick Man as Native American

Department of Integrative Biology - Fri, 06/19/2015 - 05:46

An ancient human skeleton called Kennewick Man, found on the banks of the Columbia River in 1996, has been at the center of a dispute between Native Americans and scientists on the disposition of the remains. A new analysis of DNA from the bones by a team that includes Professor Rasmus Nielsen concludes that the man probably was an ancestor of local Native American tribes. Read More

Controversial ‘Kennewick Man’ was an 8,500-year-old Native American

UC Berkeley Science News - Thu, 06/18/2015 - 09:00
The discovery of an ancient human skeleton on the banks of the Columbia River in 1996 ignited a controversy when local Native Americans claimed the remains for reburial and scientists protested that they should first be studied. A new analysis of DNA from the bones by a team that includes IB professor Rasmus Nielsen concludes that the man probably was an ancestor of local tribes.

Humans’ built-in GPS is our 3-D sense of smell

UC Berkeley Science News - Wed, 06/17/2015 - 10:00
Like homing pigeons, humans have a nose for navigation because our brains are wired to convert smells into spatial information, new research shows. Similar investigations have been conducted on birds and rodents, but this is the first time smell-based navigation has been field-tested on humans. The results evoke a GPS-like superpower one could call an “olfactory positioning system.”

Anderson lab develops potential molecular lock and key for GMOs

Department of Bioengineering - Tue, 06/16/2015 - 12:47
Researchers in bioengineering professor Chris Anderson’s lab have used synthetic biology to develop an easy way to lock down bacteria, to contain its accidental spread. The work, led by recent BioE Ph.D. Gabriel Lopez, shows promise as a potential method of containing advances created through synthetic biology and genetic engineering.

Scientists use molecular ‘lock and key’ for potential control of GMOs

UC Berkeley Science News - Tue, 06/16/2015 - 04:00
UC Berkeley researchers have developed a way to put bacteria under a molecular lock and key as a way to contain its accidental spread. The method involves a series of genetic mutations that render the microbe inactive unless the right molecule is added to enable its viability.

Why anti-depressants can make you itch

UC Berkeley Science News - Mon, 06/15/2015 - 07:48
Why anti-depressants can make you itchAnti-depressants, which prevent serotonin from being broken down, can also make people itch. UC Berkeley's Diana Bautista and Buck Institute investigators think they know why: at least in mice, there are itch receptors in the skin triggered by serotonin. The finding could lead to new anti-itch drugs.
