You may not think of plants as needing life-saving medicine, but that’s sometimes the case when bugs and disease strike. Now, scientists have developed a super-accurate, highly delicate way of delivering drugs, and right where plants need them.   At the moment, plants can be sprayed with pesticides, which doesn’t really penetrate to the roots,

NASA engineers have designed a mass-producible ventilator tailored to coronavirus patients, and it could get emergency approval from the Food and Drug Administration by the weekend.   A team of engineers at the Jet Propulsion Laboratory in Pasadena, California, designed and built the ventilator in just 37 days. The device, called VITAL as an acronym

Whether you use Zoom, Skype or Microsoft Teams, the webcam on your home PC or laptop device has probably never been as active as it is during this pandemic. Most of us have a camera built into our phone, tablet, laptop, or a desktop webcam we use for work, study or virtual socialising.   Unfortunately,

Today, the world is grappling with more than just the climate crisis, and yet even now, in the face of a global pandemic, scientists are marching on with renewable solutions. Just this month, no less than three records have been broken in solar panel efficiency. The first and the second were achieved by scientists in

Much of the work undertaken by artificial intelligence involves a training process known as machine learning, where AI gets better at a task such as recognising a cat or mapping a route the more it does it. Now that same technique is being use to create new AI systems, without any human intervention.   For

As quantum computers continue to grow in size and complexity, engineers are hitting a major obstacle. All of that added machinery means higher temperatures – and if anything can ruin a perfectly good quantum bit, it’s heat.   There are a few possible solutions, but any fix needs to be small and compatible with existing

You may have heard of [email protected], the number-crunching app you can run on your computer to help researchers tackle certain medical problems, including the new coronavirus. In the past month, the network of volunteers who’ve installed it has become so vast, the platform is outperforming the most powerful supercomputers in the world.   According to

They found it buried in the muddy shores of the Potomac River more than three decades ago: a strange “sediment organism” that could do things nobody had ever seen before in bacteria.   This unusual microbe, belonging to the Geobacter genus, was first noted for its ability to produce magnetite in the absence of oxygen, but with

Physics experts are working at Europe’s CERN lab to create a basic ventilator for mild coronavirus sufferers and recovering patients, the facility said on Wednesday. The Swiss-based lab says a model that could run on batteries should be ready for testing in hospitals within weeks and could eventually free up heavy-duty machines for use on

Researchers working for industrial development company Carbios have created a mutant bacterial enzyme that can break down plastic bottles for recycling in only a couple of hours, according to The Guardian.   The enyzme can break down PET plastic bottles into their individual chemical composites, which could later be reused to make brand new bottles. Conventional

A conspiracy theory claiming 5G can spread the coronavirus is making the rounds on social media. The myth supposedly gained traction when a Belgian doctor linked the “dangers” of 5G technology to the virus during an interview in January.   Closer to home, Facebook group Stop5G Australia (with more than 31,700 members) has various posts

“Zoombombing” in case you haven’t heard, is the unsavoury practice of posting distressing comments, pictures or videos after gatecrashing virtual meetings hosted by the videoconferencing app Zoom.   With hundreds of millions around the world now reliant on the app for work, this unfortunate trend is becoming more common, often involving a bombardment of pornographic

Scientists have developed a prototype system that could hypothetically see data transfer rates hit 10 terabits per second – or many thousands of times faster than your average broadband speed, in other words.   This radical jump could be made possible by switching to an extremely high frequency for the data transfer, allowing for more

With #StayAtHome and social distancing now becoming a way of life, an increasing number of people are relying on the internet for work, education and entertainment. This has placed greater demand on our network infrastructure, reducing the bandwidth available for each user, and is leaving people frustrated at seemingly slow internet speeds.   While internet

Recently Facebook, Reddit, Google, LinkedIn, Microsoft, Twitter and YouTube committed to removing coronavirus-related misinformation from their platforms. COVID-19 is being described as the first major pandemic of the social media age. In troubling times, social media helps distribute vital knowledge to the masses. Unfortunately, this comes with myriad misinformation, much of which is spread through

The world is only just getting used to the power and sophistication of virtual assistants made by companies like Amazon and Google, which can decode our spoken speech with eerie precision compared to what the technology was capable of only a few short years ago.   In truth, however, a far more impressive and mind-boggling

With the right mechanical contraption attached, human running speeds could rival those of cyclists, according to new research – getting runners up to 20.9 metres per second, or more than 46 miles per hour.   It’s worth noting that these are theoretical calculations for now, and the team responsible is hoping to have their prototype

Electric cars absolutely do produce less CO2 than gas guzzlers, a new study has confirmed – countering claims that carbon emissions from the manufacture of electric cars and the production of electricity outweighed the savings on the road.   Crunching the numbers on data collected from 59 different regions in the world that represent 95
