For Patrick Druckenmiller, the Earth sciences curator at the Univ. of Alaska Museum, the discovery of an ancient marine reptile fossil in the Alaskan mountains illustrates the perfect marriage between nonprofessional and professional paleontologists when it comes to fossil discovery.
As many of the world’s nations prepare and implement plans to cut greenhouse gas emissions, researchers say another critical factor needs to be considered. A new study has found, for the first time, that efforts to keep global temperatures in check will likely lead to more people going hungry. That risk doesn’t negate the need for mitigation but highlights the importance of comprehensive policies.
Using a climate model that can tag sources of soot from different global regions and can track where it lands on the Tibetan Plateau, researchers have determined which areas around the plateau contribute the most soot—and where. The model can also suggest the most effective way to reduce soot on the plateau, easing the amount of warming the region undergoes.
A team of researchers has passed a major milestone in molecular electronics with the creation of the world’s highest-performance single-molecule diode. Working at Berkeley Lab’s Molecular Foundry, the team used a combination of gold electrodes and an ionic solution to create a single-molecule diode that outperforms the best of its predecessors by a factor of 50.
Researchers at the Univ. of Illinois at Chicago and Northwestern Univ. have engineered a tethered ribosome that works nearly as well as the authentic cellular component, or organelle, that produces all the proteins and enzymes within the cell. The engineered ribosome may enable the production of new drugs and next-generation biomaterials and lead to a better understanding of how ribosomes function.
HEMCO's UniFlow Trace Metal Fume Hoods are specifically designed for applications where for accurate testing results, it's imperative that the fume hood be constructed of non-metallic materials. The fume hoods are suitable for water treatment, marine and soil sciences, environmental toxic analysis and toxicology.
In 2013, solar was the second-largest source of new electricity generating capacity in the U.S., exceeded only by natural gas. A USA SunShot Vision Study suggests solar power could provide as much as 14% of U.S. electricity demand by 2030, and 27% by 2050. There are currently two main customers for renewable energy forecasting technologies: utility companies and independent system operators (ISOs).
For consumers searching for just the right sunblock this summer, the options can be overwhelming. But scientists are now turning to the natural sunscreen of algae—which is also found in fish slime—to make a novel kind of shield against the sun’s rays that could protect not only people, but also textiles and outdoor materials.
Rice serves as the staple food for more than half of the world's population, but it's also the one of the largest manmade sources of atmospheric methane, a potent greenhouse gas. Now, with the addition of a single gene, rice can be cultivated to emit virtually no methane from its paddies during growth. It also packs much more of the plant's desired properties, such as starch for a richer food source and biomass for energy production.
An exotic material called gallium nitride (GaN) is poised to become the next semiconductor for power electronics, enabling much higher efficiency than silicon. In 2013, the U.S. Dept. of Energy dedicated approximately half of a $140 million research institute for power electronics to GaN research, citing its potential to reduce worldwide energy consumption.
Global rollouts of Microsoft’s new operating system (OS) Windows 10 begin at midnight and, with the release, the company is “opting for significance over stability,” according to Kevin Paul Scott, co-founder of brand consulting firm ADDO Worldwide.
Researchers at Princeton Univ. have developed a new chemical reaction that breaks the strongest bond in a molecule instead of the weakest, completely reversing the norm for reactions in which bonds are evenly split to form reactive intermediates.
Every Wednesday, R&D Magazine will feature a R&D 100 Flashback, chosen from our R&D 100 roster of past winners who have presented an innovative technology or product. This week’s flashback is Pacific Northwest National Laboratory’s Combined Orthogonal Mobility & Mass Evaluation Technology (CoMet), which won in 2013.
As a New Hampshire facility for people with brain injuries and developmental disabilities prepares to close after months of scrutiny over allegations of abuse, the families of the people who live there are scrambling to find new placements for their loved ones. Just 10 people remain at Lakeview NeuroRehabilitation Center, an 88-bed facility near the Maine border.
The discovery of a previously unknown type of metal deformation, sinuous flow, and a method to suppress it could lead to more efficient machining and other manufacturing advances by reducing the force and energy required to process metals. Researchers at Purdue Univ. discovered sinuous flow deformation and were surprised to find a potentially simple way to control it.
