  • New super-resolution method reveals fine details without constantly needing to zoom in
    Since the early 1930s, electron microscopy has provided unprecedented access to the alien world of the extraordinarily small, revealing intricate details that are otherwise impossible to discern with conventional light microscopy. But to achieve high resolution over a large specimen area, the energy of the electron beams needs to be cranked up, which is costly and detrimental to the specimen under observation.
  • New study suggests ADHD- like behavior helps spur entrepreneurial activity
    Many people have experienced a few nights of bad sleep that resulted in shifting attention spans, impulsive tendencies and hyperactivity the next day -- all behaviors resembling ADHD. A new study found that this dynamic may also be linked to increased entrepreneurial behavior.
  • Swallowing this colonoscopy-like bacteria grabber could reveal secrets about your health
    Your gut bacteria could say a lot about you, such as why you're diabetic or how you respond to certain drugs. But scientists can see only so much of the gastrointestinal tract to study the role of gut bacteria in your health. Researchers built a way to swallow a tool that acts like a colonoscopy, except that instead of looking at the colon with a camera, the technology takes samples of bacteria.
  • Programmed bacteria have something extra

  • Human milk based fortifiers improve health outcomes for the smallest premature babies
    More than 380,000 babies are born prematurely in the United States each year, according to the March of Dimes. 'Preemies' can be severely underweight babies and struggle to get the nutrients they need from breast milk alone, so neonatal intensive care units provide an additional milk fortifier, either in the form of cow's milk or manufactured from donor breast milk, to keep them healthy.
  • Mutations may have saved brown howlers from yellow fever virus
    From 2007 to 2009, a devastating yellow fever virus outbreak nearly decimated brown and black and gold howler monkey populations at El Parque El Piñalito in northeastern Argentina. An international research team tested if howlers who survived the outbreak had any genetic variations that may have kept them alive. In brown howlers, they found two mutations on immune genes that resulted in amino acid changes in the part of the protein that detects the disease.
  • Young children would rather explore than get rewards
    Young children will pass up rewards they know they can collect to explore other options, a new study suggests. Researchers found that when adults and 4- to 5-year-old children played a game where certain choices earned them rewards, both adults and children quickly learned what choices would give them the biggest returns. But while adults then used that knowledge to maximize their prizes, children continued exploring the other options.

  • Adaptation in single neurons provides memory for language processing
    To understand language, we have to remember the words that were uttered and combine them into an interpretation. How does the brain retain information long enough to accomplish this, despite the fact that neuronal firing events are very short-lived? Researchers propose a neurobiological explanation bridging this discrepancy. Neurons change their spike rate based on experience and this adaptation provides memory for sentence processing.

  • Extremely young galaxy is Milky Way look-alike
    Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have revealed an extremely distant and therefore very young galaxy that looks surprisingly like our Milky Way. The galaxy is so far away its light has taken more than 12 billion years to reach us: we see it as it was when the Universe was just 1.4 billion years old. It is also surprisingly unchaotic, contradicting theories that all galaxies in the early Universe were turbulent and unstable.

To identify several candidates, they developed a drug discovery pipeline -- a type of computational strategy linked to artificial intelligence.
  • New way to make bacteria more sensitive to antibiotics discovered
    Researchers have discovered a new way to reverse antibiotic resistance in some bacteria using hydrogen sulphide (H2S). By adding H2S releasing compounds to Acinetobacter baumannii - a pathogenic bacteria that does not produce H2S on its own - they found that exogenous H2S sensitised the A. baumannii to multiple antibiotic classes. It was even able to reverse acquired resistance in A. baumannii to gentamicin.
  • Security gap allows eavesdropping on mobile phone calls
    Calls via the LTE mobile network, also known as 4G, are encrypted and should therefore be tap-proof. However, researchers have shown that this is not always the case. They were able to decrypt the contents of telephone calls if they were in the same radio cell as their target, whose mobile phone they then called immediately following the call they wanted to intercept. They exploit a flaw that some manufacturers had made in implementing the base stations.
