Recent work by Los Alamos National Laboratory experimental and theoretical biologists describes a new method of controlling gene expression. The key is a tunable switch made from a small non-coding RNA molecule that could have value for medical and even biofuel production purposes.
In Kimberley Hamad-Schifferli’s hand, the device looks like a white iPod Mini, small enough to fit in a pants pocket. However, this device is actually a paper-based, rapid diagnostic test capable of finding the presence of infectious diseases, including Ebola, dengue and yellow fever.
New research findings from Bangor Univ. and Trinity College Dublin have highlighted the potential for further cost savings from micro-hydropower. Savings of up to an additional £1m a year in Wales alone could help keep water bills down. The water industry consumes a vast amount of energy due to the need to treat, pump and distribute water and wastewater around the country.
Graham George and Ingrid Pickering, a husband and wife x-ray research team, have worked for decades to understand how contaminants in water and soil are taken up by the body and affect human health. Much of that research has taken place at the Stanford Synchrotron Radiation Lightsource, where both are former staff scientists.
Boston Dynamics, a robotics company owned by Google, posted footage of a prototype of their robot, named Atlas, taking a walk through the woods.
A booming economy and population led China to emerge in 2006 as the global leader in fossil-fuel carbon emissions, a distinction it still maintains. But exactly how much carbon China releases has been a topic of debate, with recent estimates varying by as much as 15%.
Besides the atoms that make up our bodies and all of the objects we encounter in everyday life, the universe also contains mysterious dark matter and dark energy. The latter, which causes galaxies to accelerate away from one another, constitutes the majority of the universe’s energy and mass.
In the battle against head lice in schools, nurses are usually on the frontlines. However, pyrethroids, commonly found in over-the-counter lice medication, are losing their effect on lice. But this isn’t a new development. According to Kyong Yoon, of Southern Illinois Univ., lice resistance to pyrethroids first appeared in Israel in 1995, a mere three years after it was introduced to the market.
Bacteria are pretty wily creatures. Take for example, an organism such as Salmonella, which are killed by antibiotics in lab tests, but can become highly resistant in the body. It is an example of what Univ. of California, Santa Barbara biologist Michael Mahan refers to as the Trojan horse strategy.
Mimicking photosynthesis is not easy. The bottleneck of artificial photosynthesis is visible light, because converting it into other forms of energy is not efficient. Researchers at Michigan Technological Univ. have found a way to solve this issue, leading to an efficient technique to produce hydrogen fuel.
Rice Univ. scientists are cleaning soil contaminated by oil spills in a way that saves energy and reclaims the soil’s fertility. They use a process known as pyrolysis, which involves heating contaminated soils in the absence of oxygen. This approach is much better for the environment than standard incineration techniques for fast remediation, said Rice environmental engineer Pedro Alvarez.
Rice Univ. chemists who developed a unique form of graphene have found a way to embed metallic nanoparticles that turn the material into a useful catalyst for fuel cells and other applications. Laser-induced graphene, created by the Rice lab of chemist James Tour last year, is a flexible film with a surface of porous graphene made by exposing a common plastic known as polyimide to a commercial laser-scribing beam.
Imagine you’re back in elementary school. Upon hearing the recess bell, you leave your pencils and books, and rush outside to the alluring glint of the playground in the sunlight. You ascend the slide’s steps, but hesitate. You touch the metal surface and pull back immediately. The metal is overwhelmingly hot from sunlight exposure.
An international group of researchers led by Carnegie Mellon Univ. physicists Mathias Lösche and Frank Heinrich have established the structure of an important tumor-suppressing protein, PTEN. Their findings provide new insights into how the protein regulates cell growth and how mutations in the gene that encodes the protein can lead to cancer.
In the 1930s, Irving Langmuir and his colleague Katharine Blodgett were working long days in the General Electric Company’s research laboratory. Together, they discovered that by spreading molecules with volatile organic solvents on the surface of water, they could create a one-molecule-thick film and use it as an anti-reflective coating for glass.
