Nature Communications
Forbidden quantum leaps possible with high-res spectroscopy
A new twist on an old tool lets scientists use light to study and control matter with 1,000 times better resolution and precision than previously possible.

The first ever photograph of light as a particle and a wave
Light behaves both as a particle and as a wave. Since the days of Einstein, scientists have been trying to directly observe both of these aspects of light at the same time. Now, scientists at EPFL have succeeded in capturing the first-ever snapshot of this dual behavior.

Core work: Iron vapor gives clues to formation of Earth and moon
One of the world's most powerful radiation sources provides scientists clues about Earth's formation and how iron vaporizes.

First detailed microscopy evidence of bacteria at the lower size limit of life
Scientists have captured the first detailed microscopy images of ultra-small bacteria that are believed to be about as small as life can get. The research was led by scientists from Berkeley Lab and the University of California, Berkeley. The existence of ultra-small bacteria has been debated for two decades, but there hasn't been a comprehensive electron microscopy and DNA-based description of the microbes until now.

New CMI process recycles valuable rare earth metals from old electronics
Scientists at the Critical Materials Institute, headquartered at the Ames Laboratory, have developed a two-step recovery process that makes recycling rare-earth metals easier and more cost-effective. The process uses differences between the solubility properties of difference elements to separate out rare-earth metals.

UCLA physicists offer a solution to the puzzle of the origin of matter in the universe
Most of the laws of nature treat particles and antiparticles equally, but stars and planets are made of particles, or matter, and not antiparticles, or antimatter. That asymmetry, which favors matter to a very small degree, has puzzled scientists for many years. UCLA physicists offer a possible solution to the mystery of the origin of matter in the universe.

New flow battery to keep big cities lit, green and safe
The new zinc-polyiodide redox flow battery uses an electrolyte that has more than two times the energy density of the next-best flow battery used to store renewable energy and support the power grid. It's high energy density, and resulting lower cost, make it ideal for large cities where space is at a premium.

In quest for better lithium-air batteries, chemists boost carbon's stability
Chemists Dunwei Wang, of Boston College, and Wei Fan, of the University of Massachusetts Amherst, report nano-coatings increased the stability of a unique form of carbon, yielding performance gains focused on next generation lithium-air batteries.

First direct observation of carbon dioxide's increasing greenhouse effect at the Earth's surface
Scientists have observed an increase in carbon dioxide's greenhouse effect at the Earth's surface for the first time. The researchers, led by scientists from the US Department of Energy's Lawrence Berkeley National Laboratory, measured atmospheric carbon dioxide's increasing capacity to absorb thermal radiation emitted from the Earth's surface over an eleven-year period at two locations in North America. They attributed this upward trend to rising carbon dioxide levels from fossil fuel emissions.

Dendrite eraser: New electrolyte rids batteries of short-circuiting fibers
A new electrolyte allows rechargeable batteries to operate well without growing dendrites, tiny pin-like fibers that short-circuit rechargeable batteries.

Massive amounts of Saharan dust fertilize the Amazon rainforest
Every year, millions of tons of nutrient-rich Saharan dust cross the Atlantic Ocean, bringing vital phosphorus and other fertilizers to depleted Amazon soils. For the first time, scientists have an accurate estimate of how much phosphorus makes this trans-Atlantic journey.

Nature Genetics
Retracing the roots of fungal symbioses
In the roots of host plants, mycorrhizal fungi exchange the sugars plants produce for nutrients they absorb from the soil. To understand the basis for fungal symbiotic relationships with plants, DOE Joint Genome Institute researchers and longtime collaborators reported the first broad, comparative phylogenomic analysis of mycorrhizal fungi in the Feb. 23, 2015 edition of Nature Genetics. The results help researchers understand how the mutualistic association provides host plants with beneficial traits for environmental adaptation.

Giving shape to black holes' intense winds
By looking at the speed of ambient gas spewing out from a well-known quasar, astronomers are gaining insight into how black holes and their host galaxies might have evolved at the same time.

Evolution may hold the key to more designer cancer drugs like Gleevec
Dorothee Kern, a professor of biochemistry and Howard Hughes Medical Institute investigator, unraveled the journey of two closely related cancer-causing proteins -- one susceptible to the drug Gleevec and one not -- over one billion years of evolution. She and her team pinpointed the exact evolutionary shifts that caused Gleevec to bind well with one and poorly with the other. This new approach may have a major impact on the development of rational drugs to fight cancer.

Medtech meets cleantech: Malaria vaccine candidate produced from algae
Researchers at University of California, San Diego School of Medicine used algae as a mini-factory to produce a malaria parasite protein. The algae-produced protein, paired with an immune-boosting cocktail suitable for use in humans, generated antibodies in mice that nearly eliminated mosquito infection by the malaria parasite. The method, published Feb. 17 by Infection and Immunity, is the newest attempt to develop a vaccine that prevents transmission of the malaria parasite from host to mosquito.
