  When you're paid to sell things, it doesn't hurt to be able to stretch the truth or prey on people's emotions once in a while. Most advertisers probably don't spend too much time thinking about karma, then, but perhaps they should—at least if they want to get better at their jobs.

• Steps that lead to genes being switched on revealed in atomic simulation

  13-05-2016 20:00
  
  Proteins are essential for processes that sustain life. They are created in cells through a process called gene expression, which uses instructions from stretches of DNA called genes to build proteins. Sometimes genes are faulty and create proteins that contain errors, preventing the cell from functioning properly. These lead to genetic diseases like cystic fibrosis and haemophilia.

• Researchers unleash graphene 'tiger' for more efficient optoelectronics

  13-05-2016 20:00
  
  In the quest to harvest light for electronics, the focal point is the moment when photons—light particles—encounter electrons, those negatively-charged subatomic particles that form the basis of our modern electronic lives. If conditions are right when electrons and photons meet, an exchange of energy can occur. Maximizing that transfer of energy is the key to making efficient light-captured energetics possible.

  Sharks, skates, and rays can detect very weak electric fields produced by prey and other animals using an array of unusual organs known as the ampullae of Lorenzini. Exactly how these electrosensory organs work has remained a mystery, but a new study has revealed an important clue that may have implications for other fields of research.

• Retreat of the ice followed by millennia of methane release

  13-05-2016 18:14
  
  Scientists have calculated that the present day ice sheets keep vast amounts of climate gas methane in check. Ice sheets are heavy and cold, providing pressure and temperatures that contain methane in form of ice-like substance called gas hydrate. If the ice sheets retreat the weight of the ice will be lifted from the ocean floor, the gas hydrates will be destabilised and the methane will be released.

  Researchers and businesses have often operated under the idea that work-related cultural values are defined by country - just think of stereotypes about countries that are known to have hard workers or are team-oriented. A new study finds that nationality is actually a bad proxy for work-related cultural values, and points to other groupings - such as occupation - as more reliable indicators.

  Together with irregular galaxies, spiral galaxies make up approximately 60 percent of the galaxies in the local universe. However, despite their prevalence, each spiral galaxy is unique—like snowflakes, no two are alike. This is demonstrated by the striking face-on spiral galaxy NGC 6814, whose luminous nucleus and spectacular sweeping arms, rippled with an intricate pattern of dark dust, are captured in this NASA/ESA Hubble Space Telescope image.
