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.

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.

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.

How iron feels the heat
Researchers have known that the arrangement of the atoms in a piece of iron changes several times before melting -- but the details of just how and why this property contributes to the metal's thermodynamic stability remained a mystery. Recent work at Caltech provides evidence for how iron's magnetism plays a role in this curious property--an understanding that could help researchers develop better and stronger steel.

Geoengineering report: Scientists urge more research on climate intervention
Deep cuts in greenhouse gas emissions, while necessary, may not happen soon enough to stave off climate catastrophe. So, in addition, the world may need to resort to so-called geoengineering approaches that aim to deliberately control the planet's climate.

New catalyst uses light to convert nitrogen to ammonia
Northwestern University scientists are the first to develop a catalyst that can perform a remarkable feat found only in nature: take nitrogen from the air and turn it into ammonia under natural conditions. No high temperatures or pressure required. Driven by light, the new method offers promise for a more environmentally friendly fertilizer. Ammonia is the critical component in fertilizer.

IU biologists partner bacterium with nitrogen gas to produce more, cleaner bioethanol
Indiana University biologists believe they have found a faster, cheaper and cleaner way to increase bioethanol production by using nitrogen gas, the most abundant gas in Earth's atmosphere, in place of more costly industrial fertilizers. The discovery could save the industry millions of dollars and make cellulosic ethanol -- made from wood, grasses and inedible parts of plants -- more competitive with corn ethanol and gasoline.

New method allows for greater variation in band gap tunability
By manipulating the ordered arrangement of atoms in layered complex oxide materials, Northwestern University's James Rondinelli has found a way to control their electronic band gaps, which determines the electrical behavior of the material and how it interacts with light.

Researchers make magnetic graphene
Graphene has many desirable properties. Magnetism alas is not one of them. Magnetism can be induced in graphene by doping it with magnetic impurities, but this tends to disrupt graphene's electronic properties. Now a team of UC Riverside physicists has found a way to induce magnetism in graphene while also preserving graphene's electronic properties. They have accomplished this by bringing a graphene sheet very close to a magnetic insulator -- an electrical insulator with magnetic properties.

'Assassin' targets supernovae in our neighborhood of the universe
While many astronomical collaborations use powerful telescopes to target individual objects in the distant universe, a new project at The Ohio State University is doing something radically different: using small telescopes to study a growing portion of the nearby universe all at once. Since it officially launched in May 2014, the project has detected 89 bright supernovae and counting -- more than all other professional astronomical surveys combined.
