Launched in 2018, NASA’s Parker Solar Probe spacecraft, with instruments developed and built by UC Berkeley, has now traveled closer to the sun than any other mission in history, actually penetrating the sun’s atmosphere, to investigate highly charged magnetic field. Now, that data has allowed solar physicists to map the source of a major component of the solar wind that continually peppers Earth’s atmosphere, while revealing strange magnetic field reversals that could be accelerating these particles toward our planet. These accelerated particles interact with Earth’s magnetic field, generating the colorful northern and southern lights but also potentially damaging the electrical grid and telecommunications networks on the surface, threatening orbiting satellites and perhaps endangering astronauts in space.

A new fly-through of the fly brain allows anyone to whizz past neurons and visit any of the 40 million synapses where neurons touch neuron. It's a super-resolution view of the complex network connections in the insect's brain that underlie behaviors ranging from feeding to mating. What's unprecedented, however, is that this 3D map over the whole fly brain, which shows details as small as 60 nanometers across, was captured in less than three days. While the level of detail is not quite as good as that obtained with an electron microscope, efforts to fully map the neurons and synapses of the fly brain with EM have taken 10 years and the efforts of dozens of people. The new map was obtained a thousand times faster by combining two state-of-the-art techniques, expansion microscopy and lattice light-sheet microscopy.

Most hummingbirds have bills and tongues exquisitely designed to slip inside a flower, lap up nectar and squeeze every last drop of precious sugar water from their tongue to fuel their frenetic lifestyle. But in the tropics of South America, University of California, Berkeley, scientists are finding that some male hummers have traded efficient feeding for bills that are better at stabbing and plucking other hummingbirds as they fend off rivals for food and mates. The males weaponized bills are good not only for pulling feathers and pinching skin, but also wrestling their rivals away from prime feeding spots.

Can geoengineering save the planet? Injecting particles into the atmosphere to counter the warming effects of climate change would do nothing to offset the crop damage from rising global temperatures, according to a new analysis by UC Berkeley researchers. Shading the planet keeps things cooler, which helps crops grow better. But plants also need sunlight to grow, so blocking sunlight can affect growth.

In October of 2018, a UC Berkeley team headed down to the Arizona desert with their newest prototype water harvester. In the backyard of a tract home it sucked water out of the air without any power other than sunlight. The successful field proved what the team had predicted; the water harvester can extract drinkable water every day/night cycle at very low humidity and at low cost, making it ideal for people living in arid, water-starved areas of the world.

UC Berkeley mechanical engineers have shown why your shoelaces keep coming untied. It’s a question that everyone asks themselves, often after stopping to retie their shoes, yet no one had investigated. The answer, the study suggests, is that a double whammy of stomping and whipping forces act like an invisible hand, loosening the knot and then tugging on the free ends of your laces until the whole thing unravels. Using a slow-motion camera and a series of experiments, the study shows that shoelace knot failure happens in a matter of seconds, triggered by a complex interaction of forces. The study is more than an example of science answering a seemingly obvious question. A better understanding of knot mechanics is needed for sharper insight into how knotted structures fail under a variety of forces. Series: "UC Berkeley News" [Science] [Show ID: 32685]

When you're suddenly able to understand someone despite their thick accent, or finally make out the lyrics of a song, your brain appears to be re-tuning to recognize speech that was previously incomprehensible. University of California, Berkeley, neuroscientists have now observed this re-tuning in action by recording directly from the surface of a person's brain as the words of a previously unintelligible sentence suddenly pop out after the subject is told the meaning of the garbled speech. The re-tuning takes place within a second or less, they found. The findings will aid Knight and his colleagues in their quest to develop a speech decoder: a device implanted in the brain that would interpret people's imagined speech and help speechless patients, such as those paralyzed by Lou Gehrig's disease, communicate.

When you're suddenly able to understand someone despite their thick accent, or finally make out the lyrics of a song, your brain appears to be re-tuning to recognize speech that was previously incomprehensible. University of California, Berkeley, neuroscientists have now observed this re-tuning in action by recording directly from the surface of a person's brain as the words of a previously unintelligible sentence suddenly pop out after the subject is told the meaning of the garbled speech. The re-tuning takes place within a second or less, they found. The findings will aid Knight and his colleagues in their quest to develop a speech decoder: a device implanted in the brain that would interpret people's imagined speech and help speechless patients, such as those paralyzed by Lou Gehrig's disease, communicate.

Calcium, the main constituent of bone, turns out to play a major role in regulating the cells that orchestrate bone growth, a finding that could affect treatment for conditions caused by too much collagen deposition, such as fibrosis and excessive scarring, as well as diseases of too little bone growth, such as Treacher Collins Syndrome (TCS). The finding by Michael Rape and his colleagues at UC Berkeley came from study of the signals that tell undifferentiated stem cells in the very early embryo to mature into bone cells. As a result, people like Francis Smith, a University of Colorado researcher who visited Rape in his lab, require dozens of surgeries during childhood to reconstruct the face, implant hearing aids and even reconstruct the trachea to breathe normally. Rape hopes that basic research to pinpoint the key signals that trigger proper bone growth can help those like Smith avoid such painful surgeries.

Richard Allen, professor and director of the UC Berkeley Seismological Laboratory, discusses the lessons learned from the 1989 Loma Prieta earthquake which was centered on a section of the San Andreas Fault near Santa Cruz. It shook Northern California at 5:04 p.m., causing 63 deaths, several thousand injuries, and $6 billion in property damage, including the collapse of a section of the upper deck of the Bay Bridge, a section of the Interstate 880 freeway in Oakland, and many residential homes in San Francisco’s Marina District.

UC Berkeley engineers perform "shake tests" on a scale-model steel bridge to demonstrate a new bridge design that they say can better resist significant earthquake damage. The tests were conducted with ground motions equivalent to large quakes that have hit California, Chile, Japan and other parts of the world. The bridge segments are supported by seismic isolators and utilize a new Segmental Displacement Control Isolation System. The system is designed with lockup guides between bridge segments to constrain movement during a quake, allowing the roadway's center line to remain continuous. The strategy is meant to improve driver safety while minimizing damage to the bridge and the joints between the bridge segments. The research is being conducted by Pacific Earthquake Engineering Research Center (PEER), a consortium of nine universities on the West Coast, headquartered at UC Berkeley.
