Scientists have developed a new way of achieving artificial photosynthesis, producing high-energy hydrocarbons by leveraging electron-rich gold nanoparticles as a catalyst. In photosynthesis, plants convert energy from sunlight into glucose by rearranging molecules of water and carbon dioxide. The new process mimics this natural ability via chemical manipulations that create liquid fuel, without requiring chlorophyll.

Scientists in Germany have hit a new superconductivity milestone – achieving a resistance-free electrical current at the highest temperature yet: just 250 Kelvin, or -23 degrees Celsius (-9.4 degrees Fahrenheit). The work was led by Mikhail Eremets, a physicist at the Max Planck Institute for Chemistry, who set the previous high temperature record for superconductivity

The city of Baltimore is under attack, but not by someone armed with guns or bombs. Two weeks ago, cybercriminals used ransomware known as RobinHood to seize control of about 10,000 of the city’s computers, saying they won’t relinquish access unless Baltimore hands over about US$100,000 worth of bitcoin. Baltimore is refusing the meet the

It’s been almost exactly one year since US scientists reported a mysterious surge in ozone-destroying chemicals, known as chlorofluorocarbons (CFCs). Banned in 1987 under the globally signed Montreal Protocol, there was only one explanation: somewhere out there, in an unknown location, someone must have gone rogue, setting back progress on the ozone hole by a

Hurricane season doesn’t start until June 1, but the National Hurricane Center announced Monday evening that Subtropical Storm Andrea had formed. Called a subtropical storm because it has a blend of both tropical and nontropical characteristics, it is packing peak winds of 40 mph (64 kilometres per hour). The storm could strengthen slightly through Tuesday

Millions of cryptocurrency investors have been scammed out of massive sums of real money. In 2018, losses from cryptocurrency-related crimes amounted to US$1.7 billion. The criminals use both old-fashioned and new-technology tactics to swindle their marks in schemes based on digital currencies exchanged through online databases called blockchains. From researching blockchain, cryptocurrency and cybercrime, I
