MacArthur Genius and MIT professor Linda Griffith has built an epic career as a scientist and inventor, including growing a human ear on a mouse. She now spends her days unpacking the biological mechanisms underlying endometriosis, a condition in which uterus-like tissue grows outside of the uterus. Endometriosis can be brutally painful, is regularly misdiagnosed

You’ve probably seen images of scientists peering down a microscope, looking at objects invisible to the naked eye. Indeed, microscopes are indispensable to our understanding of life. They are just as indispensable to biotechnology and medicine, for instance in our response to diseases such as COVID-19. However, the best light microscopes have hit a fundamental

The conclusion of a classified US intelligence report on the existence of alien UFOs is… inconclusive, US media reported Friday. US military and intelligence found no evidence that seemingly highly advanced unidentified flying objects sighted by military pilots were alien spacecraft, the report concludes, according to The New York Times and other media briefed on

China has achieved a new milestone in humanity’s experiments to harness the power of the stars. On Friday, the Chinese Academy of Sciences’ fusion machine reached 120 million degrees Celsius (216 million degrees Fahrenheit) and clung onto this for 101 seconds. The last time EAST (Experimental Advanced Superconducting Tokamak or HT-7U) held onto a writhing

An online game developed by a team of social psychologists could be a useful tool in the fight against misinformation, helping internet users spot misinformation and call it out for what it is: manipulative. Misinformation – often spread by automated bots, but also unsuspecting people – worms its way into our heads by appealing to a

We have developed and tested a secure new computer processor that thwarts hackers by randomly changing its underlying structure, thus making it virtually impossible to hack. Last summer, 525 security researchers spent three months trying to hack our Morpheus processor as well as others. All attempts against Morpheus failed. This study was part of a program

When you think of micro- or nanotechnology, you likely think of small electronics like your phone, a tiny robot or a microchip. But COVID-19 tests – which have proven to be central to controlling the pandemic – are also a form of miniaturized technology. Many COVID-19 tests can give results within hours without the need

Australia, one of the world-leaders in household rooftop solar panel uptake, has once again broken its own record for the number of solar panels installed in a year. In 2020, installations were up nearly 30 percent from the year before, according to an analysis from Australia’s national science agency, CSIRO. The data, compiled by energy

The United States’ offshore wind industry is tiny, with just seven wind turbines operating off Rhode Island and Virginia. The few attempts to build large-scale wind farms like Europe’s have run into long delays, but that may be about to change. On 11 May 2021, the US government issued the final federal approval for the

If you’re struggling to handle the long line of tabs open in your browser right now, you’re not alone. A small new study has found many people who browse the internet experience tab overload, saving articles to read later, leaving tasks as reminders, or burrowing down an internet hole until the stack of open web

In our efforts to rein in our overwhelming burden upon Earth’s living biosphere, every little thing adds up. Even the shape of pasta (of all things!) can make a difference in our consumption of resources. Which is why scientists have now created flat-packed pasta that’s more efficient to package and transport, but can then unfurl

Scientists have gotten one step closer to a quantum internet by creating the world’s first multinode quantum network.  Researchers at the QuTech research center in the Netherlands created the system, which is made up of three quantum nodes entangled by the spooky laws of quantum mechanics that govern subatomic particles. It is the first time that more than two

The online world is continuously expanding – always aggregating more services, more users, and more activity. Last year, the number of websites registered on the “.com” domain surpassed 150,000,000. However, more than a quarter of a century since its first commercial use, the growth of the online world is now slowing down in some key

Perovskite has a lot going for it in our search for a cheap, efficient way to harvest solar energy. With a dusting of organic molecules, these crystalline structures have been able to convert more than a quarter of the light falling onto them into electricity. Theoretically, perovskite crystals made with the right mix of materials

Algorithms can help us with everything, from choosing what music to listen to next to finding the cheapest flight online. Now, new research reveals one of the tipping points that tend to make us trust a computer’s judgment rather than a human’s. The findings offer an interesting insight into how ready we’ve become to let

A new formula for white paint has given us the whitest white yet. It reflects a jaw-dropping 98.1 percent of all light that hits it, remaining significantly cooler than the ambient temperature, even when sitting in full sunlight. If used to coat buildings, its inventors say, the paint could help in the fight against global

A series of newly surfaced images and videos of unidentified flying objects filmed by the US Navy have now been confirmed as authentic by the Pentagon. While many in the public generally refer to such mysterious sightings as UFOs, the more modern term used in defense circles is ‘Unidentified Aerial Phenomena‘ (UAPs) – and they’re

Last week, Tesla CEO Elon Musk released a video showing how his company Neuralink – a brain-computer-interface company – had advanced its technology to the point that the chip could allow a monkey to play video games with its mind. Neuralink could transition from operating on monkeys to human trials within the year, if the startup meets

We encounter artificial intelligence (AI) every day. AI describes computer systems that are able to perform tasks that normally require human intelligence. When you search something on the internet, the top results you see are decided by AI. Any recommendations you get from your favorite shopping or streaming websites will also be based on an AI algorithm.

Rechargeable lithium-ion batteries are basically everywhere, powering everything from smartphones to notebooks, earbuds to gaming devices, and so much more. But while the convenience of this ubiquitous (and Nobel Prize-winning) battery chemistry has radically changed the way we use and charge portable technology, lithium-ion is far from perfect. The performance of lithium-ion batteries degrades over

If you’ve ever gotten your phone wet in the rain, dropped it in water or spilt liquid over it, you’re not alone. One study suggests 25 percent of smartphone users have damaged their smartphone with water or some other kind of liquid. Liquid penetrating a smartphone can affect the device in several ways. It could

Scientists have isolated and harnessed that rarest of things – an organic blue food coloring found in nature – and figured out a way to produce it at scale. The discovery, made by an international team of scientists working across different fields, means that for the first time blue and other-colored foods may not have

One of the world’s largest container ships, named Ever Given, has been wedged across the Suez Canal since it was blown off course by high winds in the early hours of March 23, blocking one of the busiest maritime trade corridors in the world. The incident has created a logjam of hundreds of tankers, the

It can’t beat us. Yet. But an artificial intelligence (AI) program developed by scientists at IBM is so good at debating against humans that it may just be a matter of time before we can’t compete. Project Debater, an autonomous debating system that’s been in development for several years, is capable of arguing against humans

Greenhouses fitted with semi-transparent solar cells can generate electricity without affecting the growth and health of the plants inside, according to a new study, suggesting we could build energy-neutral greenhouses without harming crops. Researchers tested groups of red leaf lettuce under different types of glass and different wavelengths of light, keeping all other variables the

The bitcoin market now exceeds $1 trillion with its price rising tenfold in a year, but focus is shifting towards the massive power requirements needed to sustain the online currency. Here are some questions and answers about bitcoin: How much energy does it consume? Total energy consumed by the bitcoin mining process could reach 128

Scientists may have finally made a complete digital model for the Cosmos panel of a 2,000-year-old mechanical device called the Antikythera mechanism that’s believed to be the world’s first computer. First discovered in a Roman-era shipwreck by Greek sponge divers in 1900, the fragments of a shoebox-size contraption, once filled with gears and used to predict the

They say beauty lies in the eye of the beholder, but in actuality, it goes far deeper than that. The concept of physical beauty resides in the mind, defined by whatever features we find attractive in other people’s faces. These subtle preferences represent some of our most private inner thoughts – but that doesn’t mean

In the struggle to slow the runaway freight train of humanity’s destructive impact on Earth, scientists are increasingly looking at the role our oceans can play. Teaming up with industry, scientists from the University of Southern California have discovered a ‘kelp elevator’ technique that produces ample seaweed, potentially providing a high-yield biofuel to help wean

China, which last year overtook the United States as the world’s top filer of international patents, a key measure of technical innovation, increased its lead significantly in 2020, the UN said Tuesday. Even as COVID-19 took a vast human and economic toll, international patent applications continued to grow strongly, with China leading strong gains from

It was recently revealed that in 2017 Microsoft patented a chatbot which, if built, would digitally resurrect the dead. Using AI and machine learning, the proposed chatbot would bring our digital persona back to life for our family and friends to talk to. When pressed on the technology, Microsoft representatives admitted that the chatbot was

Scientists are using a radar-like weather system to watch as a storm of pathogens brew inside living tissue. The strategy is entirely novel, according to the authors, and relies on a technique very similar to Doppler radars, which can detect the motion of precipitation and predict upcoming weather patterns. Doppler ultrasounds, which use sound waves

Sometimes, while waiting for quantum computers to become ubiquitous, or wondering whatever happened to flying cars, it’s easy to forget just how far technology has come over the past 50 years. Sure, we can all list off a bunch of innovations that have changed the way the world works – the Internet, smartphones, radio telescopes

Americans often take electricity for granted – until the lights go out. The recent cold wave and storm in Texas have placed considerable focus on the Electric Reliability Council of Texas, or ERCOT, the nonprofit corporation that manages the flow of electricity to more than 26 million Texans. Together, ERCOT and similar organizations manage about

Artificial intelligence (AI) is learning more about how to work with (and on) humans. A recent study has shown how AI can learn to identify vulnerabilities in human habits and behaviours and use them to influence human decision-making. It may seem cliched to say AI is transforming every aspect of the way we live and

In a significant move, Facebook has announced it will remove any misleading claims and misinformation about the COVID-19 vaccines from both Facebook and Instagram. It’s part of a broader move to help combat fake news about the pandemic. Since December, the platform has been removing claims about the coronavirus that have been debunked by health

Scientists have developed a new kind of cryogenic computer chip capable of functioning at temperatures so cold, it approaches the theoretical limit of absolute zero. This cryogenic system, called Gooseberry, lays the groundwork for what could be a revolution in quantum computing – enabling a new generation of machines to perform calculations with thousands of

A robot inspired by the shape and delicate underwater movements of a jellyfish, allowing it to safely explore endangered coral reefs, was unveiled by British scientists on Wednesday. According to research by teams at the universities of Southampton and Edinburgh and published in the journal Science Robotics, the small robot mimics “nature’s most efficient swimmer

To artists and romantics, the twinkling of stars is visual poetry; a dance of distant light as it twists and bends through a turbulent ocean of air above our heads. Not everybody is so enamoured with our atmosphere’s distortions. To many scientists and engineers, a great deal of research and ground-to-satellite communication would be a

The idea of artificial intelligence overthrowing humankind has been talked about for many decades, and scientists have just delivered their verdict on whether we’d be able to control a high-level computer super-intelligence. The answer? Almost definitely not. The catch is that controlling a super-intelligence far beyond human comprehension would require a simulation of that super-intelligence

Scientists have created new kinds of ‘living materials’ by tweaking the base ingredients of kombucha – the popular tea drink fermented with a symbiotic culture of bacteria and yeast (aka SCOBY). This kind of ‘tea fungus’ – sometimes called ‘kombucha mother’ – can do a lot more than just produce sour-tasting beverages, it seems. By

Bitcoin continues to trade close to its all-time high reached this month. Its price is at the time of writing around US$34,000 – up about 77 percent over the past month and 305 percent over the past year. First launched in 2009 as a digital currency, Bitcoin was for a while used as digital money

Scientists have just set a new world record for high-temperature sustained plasma with the Korea Superconducting Tokamak Advanced Research (KSTAR) device, reaching an ion temperature of above 100 million degrees Celsius (180 million degrees Fahrenheit) for a period of 20 seconds. Known as Korea’s “artificial sun”, the KSTAR uses magnetic fields to generate and stabilise

Sometimes, science is all about the mind-aching big picture. Like the idea that our Universe is just a giant hologram, or that we’ve actually detected gravitational waves from a neutron star collision. Or that we might not actually have as much free will as we think… Those are really exciting concepts. But then there are other

The start of electric aviation is upon us, but it’s going to take many more years before the average environmentalist can fly guilt free on a fully electric long haul jet. In the meantime, scientists are trying to make the commercial planes we already have more sustainable, and one of the best ways to do

Within the next few decades, according to some experts, we may see the arrival of the next step in the development of artificial intelligence. So-called “artificial general intelligence“, or AGI, will have intellectual capabilities far beyond those of humans. AGI could transform human life for the better, but uncontrolled AGI could also lead to catastrophes

A newly developed glue that gets its stickiness from a magnetic field could lead to serious energy and cost savings for companies that need to stick things together on an industrial scale. To harden – or cure – the mix of chemicals in most epoxy-based glues, some kind of environmental effect like heat, light, or

Dropping your smartphone often means living with a cracked screen until your next upgrade, or footing an expensive repair bill – but researchers have been busy bringing self-healing display technology closer to a practical reality. A team from the Korea Institute of Science and Technology (KIST) has developed a self-healing electronic material that can repair
