A full-grown giant sequoia is a thirsty tree. In the height of summer, the millenia-old behemoths, some of which grow upwards of 30 stories tall, can guzzle 500 to 800 gallons of water per day. They can also survive a variety of scourges that would fell an inferior conifer — beetles, wildfires, storms. But scientists are worried the species may have met its match in the ongoing California drought.
Nate Stephenson, a research ecologist with the U.S. Geological Survey, was walking through the woods last year when he noticed some of the trees he’d been studying for decades had dropped most of their leaves. He joined forces with other researchers from the USGS, as well as from the National Park Service, U.S. Forest Service, Stanford University, UC Berkeley and the Carnegie Airborne Observatory, to launch a comprehensive health study on the sequoia.
Anthony Ambrose, a tree ecologist at University of California, Berkeley, led a recent bout of fieldwork to monitor how stressed the sequoia have been, and if, in fact, we should be worried about their longevity. A few weeks from now, his team plans to collect a slew of samples from more than 50 trees that have dropped up to 75 percent of their leaves. He hopes the research can provide real-time data to forest managers who can prioritize care for threatened trees.

Astronomers have discovered what they say is the most Earth-like planet yet detected — a distant, rocky world that’s 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.
“This is the best case for a habitable planet yet found. The results are absolutely rock solid,” University of California, Berkeley astronomer Geoff Marcy, who had no role in the discovery, said in an email.

Want to boost your eyesight? There’s an app for that.
In a new baseball study, researchers have found that training your brain with a perceptual learning app just may improve your vision.
The researchers tested the vision of baseball players at the University of California in Riverside. Then, during the 2013 NCAA Division 1 season, 19 of the players were given 25-minute brain-training sessions with an app called UltimEyes four days per week.
What did the researchers find when they did follow-up vision tests? The players who used UltimEyes reported significant improvements in seeing at a distance of 20 feet and farther, and “greater peripheral vision.” Some said that their “eyes feel stronger” and that it’s “easy to see further.”

Spiders may trap unsuspecting prey by sucking them in using electrostatic attraction, new research suggests.
The new study, published Thursday in the journal Scientific Reports, found that the spiderweb of the common cross spider (or garden spider) is attracted to electrically charged objects, with the sticky threads of spider silk arcing toward each other in response to a charged object.
Stroke of inspiration
Some flying insects, as they flap their wings, for instance, generate an electric charge. As such the new results suggest that charged bugs such as honeybees could be sucked into, and then trapped by, a spider’s sticky web as they fly by.
“Charged insects can produce a deformation of a spiderweb,” said study co-author Victor Ortega-Jimenez, a biologist at the University of California, Berkeley. “Any insect that is flying very close to the spiderweb can be trapped by the electrostatic effect.”

A robot as small as a housefly has managed the delicate task of flying and hovering the way the actual insects do.
“This is a major engineering breakthrough, 15 years in the making,” says electrical engineer Ronald Fearing, who works on robotic flies at the University of California, Berkeley. The device uses layers of ultrathin materials that can make its wings flap 120 times a second, which is on a par with a housefly’s flapping rate. This “required tremendous innovation in design and fabrication techniques”, he adds.
The robot’s wings are composed of thin polyester films reinforced with carbon fibre ribs and its ‘muscles’ are made from piezoelectric crystals, which shrink or stretch depending on the voltage applied to them.

A few key behaviors and health conditions could predict your chances of health and longevity for the next 10 years. Find out what they are.
Want to look 10 years into the future, and see how your health is holding up? Thanks to researchers at the University of California, San Francisco, you now can. They developed a checklist, published in the Journal of the American Medical Association, which fairly accurately predicts a senior’s chance of surviving another decade, providing a unique opportunity for patients and physicians to work together to lessen key health risk factors and improve seniors’ quality of life, they say.
The UCSF analysis used a nationally representative cohort of U.S. adults over age 50. Point values were assigned to each factor in the mortality index (the higher the points, the worse the risk). A risk score was then calculated for each participant based on their self-reported health indicators. In the end, there was a dramatic difference: Participants with no risk factors had a 2.8 percent chance of dying over 10 years, while those with the most risks had a 96 percent chance of dying.

The University of California has agreed to pay about $1 million to settle a lawsuit filed by UC-Davis students who were pepper-sprayed by campus police during an Occupy-style protest on campus last November, according to media reports.
