Finding the perfect match: New approach to battle drug-resistant bacteria

Antibiotics were the wonder drug of the 20th century, but bacteria evolved resistance. According to the CDC, more than 2 million people in the U.S. develop MDR infections every year. Researchers have now developed a rapid screen to pair existing FDA-approved drugs to combat MDR infections.

How phytoplankton rule the oceans

Photosynthesis is a unique biological process that has permitted the colonization of land and sea by plants and phytoplankton respectively. While the mechanisms of photosynthesis in plants are well understood, scientists are only now beginning to elucidate how the process developed in phytoplankton.

How viewing cute animals can help rekindle marital spark

One of the well-known challenges of marriage is keeping the passion alive after years of partnership, as passions tend to cool even in very happy relationships. Psychological scientists have now developed an unconventional intervention for helping a marriage maintain its spark: pictures of puppies and bunnies.

Fighting global warming and climate change requires a broad energy portfolio

Can the continental United States make a rapid, reliable and low-cost transition to an energy system that relies almost exclusively on wind, solar and hydroelectric power? While there is growing excitement for this vision, a new study describes a more complicated reality. Researchers argue that achieving net-zero carbon emissions requires the incorporation of a much broader suite of energy sources and approaches.

Transforming last night’s leftovers into green energy

In a classic tale of turning trash into treasure, two different processes soon may be the favored dynamic duo to turn food waste into green energy, according to a study.

Monitoring soil structure changes after compaction

Soil compaction is a global threat to soil ecosystem services, causing tremendous costs to society. The costs of soil compaction are borne by the cumulative loss of soil functionality (e.g. yield loss) following a compaction event until the soil has functionally recovered. Although soil compaction is relatively widely studied, there is a lack of reliable observations and metrics for soil structure recovery rates after compaction.

Biofuel for Conventional Diesel Engines Created

In accordance with an EU directive, conventional automotive diesel is supplemented with seven percent biodiesel. This proportion is set to rise to ten percent by 2020. However, this presents a significant technical challenge: biodiesel vaporises at higher temperatures, which can lead to problems with electronic fuel injection systems and particulate filters. Researchers have developed a method for producing a petroleum diesel-like fuel from conventional biodiesel at low temperatures.

150-year records gap on Sulawesi ends with five new species in the world’s largest...

Coming 150 years after the last description from Sulawesi, five new species from the world's largest genus of trees, Syzygium, highlight the extent of unexplored botanical diversity on the Indonesian island.

Building a better alligator: Advanced 3-D models of bite data

The ability to bite hard is critical for crocodilians to eat their food such as turtles, wildebeest and other large prey; therefore, their anatomy is closely studied by veterinarians and paleontologists who are interested in animal movements and anatomy. Now, researchers have developed three-dimensional models of the skull of the American alligator using cutting-edge imaging and computational tools.

Antibiotics promote resistance on experimental croplands

Researchers have generated both novel and existing antibiotic resistance mechanisms on experimental farmland, by exposing the soil to specific antibiotics.

Sex or food? Decision-making in single-cell organisms

Unicellular diatoms are able to adapt their behavior to different external stimuli based on an evaluation of their own needs. In experiments, Seminavis robusta diatoms directed their orientation either towards nutrient sources or mating partners, depending on the degree of starvation and the need to mate.
