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.

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

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,

Global messaging app WhatsApp, which boasts over 1 billion users, was targeted by hackers last month in a breach that saw mobile devices attacked through the voice-calling functionality of the app.   The security flaw potentially gave hackers access to private messages, location data and other personal user information. While WhatsApp hasn’t specifically stated who or how

A new ‘biological glue’ developed by Chinese researchers could one day stop hearts and arteries from uncontrollably bleeding. Placed on an open wound and activated through UV light, this life-saving sealant rapidly morphs into a non-toxic hydrogel, capable of withstanding both slippery surfaces and the pulsing of heart tissue.   The adhesive sealant hasn’t been

Personal gadgets known as “hearables,” which communicate with the neural signals passing through our ears in order to monitor and interact with our brains, are on their way.   Hearables could help us focus on specific conversations, like smart hearing aids, or monitor our brain activity to treat tinnitus. That’s according to Poppy Crum, the Stanford University neuroscientist and chief

The widespread adoption of pasteurisation and refrigeration means we’re now used to a shelf life of two to three weeks for milk, but scientists working at Australian company Naturo just announced they’ve extended that to more than 60 days.   Allegedly, Naturo’s technique doesn’t involve the heat treatment that comes with pasteurisation, and apparently “retains

SpaceX and Tesla CEO Elon Musk hinted at what could be the announcement of a brain-machine interface that could one day hook human brains up to computers on Sunday. In response to a question asking for an update on Neuralink, a neurotechnology startup he founded in 2016, Musk replied that new information would be “coming soon”.   A “direct cortical interface,” according

Scientists have developed a first-of-its-kind device that generates electricity from nothing other than the natural phenomenon of snowfall. Based upon the principles of the triboelectric effect, in which electrical charge is generated after two materials come into contact with one another, the researchers’ new technology exploits the fact that snow particles carry a positive electrical
