Mathematics of Popping Bubbles in a Foam
Bubble baths and soapy dishwater, the refreshing head on a beer and the luscious froth on a cappuccino. All are foams, beautiful yet ephemeral as the bubbles pop one by one. Now, two researchers from Berkeley Lab and the University of California, Berkeley have described mathematically the successive stages in the complex evolution and disappearance of foamy bubbles, a feat that could help in modeling industrial processes in which liquids mix or in the formation of solid foams such as those used to cushion bicycle helmets.
New Study: As Climate Changes, Boreal Forests to Shift North and Relinquish More Carbon Than Expected
It’s difficult to imagine how a degree or two of warming will affect a location. Will it rain less? What will happen to the area’s vegetation? New Berkeley Lab research offers a way to envision a warmer future. It maps how Earth’s myriad climates—and the ecosystems that depend on them—will move from one area to another as global temperatures rise. The approach foresees big changes for one of the planet’s great carbon sponges. Boreal forests will likely shift north at a steady clip this century. Along the way, the vegetation will relinquish more trapped carbon than most current climate models predict.
What Did Alexander Graham Bell’s Voice Sound Like? Berkeley Lab Scientists Help Find Out
Berkeley Lab’s sound-restoration experts have done it again. They’ve helped to digitally recover a 130-year-old recording of Alexander Graham Bell’s voice, enabling people to hear the famed inventor speak for the first time. The recording ends with Bell saying “in witness whereof, hear my voice, Alexander Graham Bell.”
The project involved a collaboration between Smithsonian’s National [...]
Running, Even in Excess, Doesn’t Lead to More Osteoarthritis and Hip Replacements
Need another reason to dust off those running shoes in the back of the closet? It turns out that running longer distances actually decreases a person’s risk of osteoarthritis and hip replacements, according to new research conducted by Paul Williams of Berkeley Lab’s Life Sciences Division.
His results counter the widely held view that frequent running [...]
New Computational Pipeline Analyzes Tumor Images, May Help Predict Response to Cancer Therapy
How’s this for big data: A whole-slide image of a tumor section can be ten billion pixels. There can be thousands of such images in the tumor cohorts maintained by The Cancer Genome Atlas project, which are collected from a large pool of patients.
The images are a potential treasure trove for the emerging field of [...]
Berkeley Lab Scientists Help Map Molecular Architecture of Organelle Critical to Hearing
To learn how something works in biology, it pays to start really small. Take this research for example: A team that includes Berkeley Lab scientists has identified and mapped the locations of many of the proteins that compose a hair bundle, which is an organelle that sprouts from hair cells in the inner ear.
Their work [...]
Another Tool in the Nano Toolbox: Berkeley Lab Scientists Use Electron Beam to Manipulate Nanoparticles
Berkeley Lab scientists have developed a way to manipulate nanoparticles using an electron beam. They used an electron beam from a transmission electron microscope to trap gold nanoparticles and direct their movement. They also used the beam to assemble several nanoparticles into a tight cluster. Based on their results, the scientists believe their approach could lead to a new way to build nanostructures one nanoparticle at a time.
