Gene editing: Pig hearts and the new era of organ transplants

“Pig hearts to be tested in humans” read a headline in the Financial Times in September 1995. The article quoted confident predictions that porcine hearts, genetically engineered to avoid rejection, would be transplanted into patients the following year — helping to ease the worldwide shortage of human organs. More than 25 years passed before that forecast finally came true. Last month surgeons at the University of Maryland School of Medicine in Baltimore successfully replaced the failing heart of a 57-year-old man with a fresh one from a pig with 10 gene edits. Four weeks later the patient, David Bennett, continues…

What the next 10 years will likely look like for smartphones

Here's how the mobile customer experience will likely evolve in the next decade. Nobody (except for Steve Jobs, maybe) could have predicted the impact of the iPhone when it was introduced in 2007. Countless other smartphones have since been released with exquisite hardware features like advanced cameras, 4K resolution and giant screens. But it wasn't these features that made people rapidly adopt smartphones-- it was the experiences these devices provide, like global social networks, music streaming, online shopping and many others. With the help of evolving technology, smartphones will enable even more groundbreaking mobile experiences in the next decade-- ones…

Most popular phone of the last 22 years revealed – and it's NOT an iPhone

The most popular phone since the millennium has been revealed and many will be shocked to find out it’s NOT an iPhone. Despite the Apple handset’s massive success since 2007, not one of the models have been able to topple an earlier giant. In fact, the majority of the top five were all released in the noughties. 2014’s iPhone 6/6+ saw 222.40million handsets sold, making it Apple’s most successful smartphone. But that only puts it at number two. The number one has been revealed as old school favourite, the Nokia 1100. The device, which boasted Snake and a built-in flashlight,…

Forget blood - your skin might know if you’re sick

This glowing microneedle test could catalyze a transition from blood-based diagnostics to a stick-on patch. A river of biological information flows just beneath the outermost layers of your skin, in which a hodgepodge of proteins squeeze past each other through the interstitial fluid surrounding your cells. This "interstitium" is an expansive and structured space, making it, to some, a newfound “organ.” But its wealth of biomarkers for conditions like tuberculosis, heart attacks, and cancer has attracted growing attention from researchers looking to upend reliance on diagnostic tools they say are inefficient, invasive, and blood-centric. "Blood is a tiny fraction of…

These electric sockets are made from a surprising material: bone

Humans have found creative uses for bones since prehistoric times. Animal bones have been shaped into spoons, needles, musical instruments, and combs. Meanwhile, bone ash—created by grinding bones to fine powder—has been used in bone china since the 1700s. Now, a designer has brought one of the planet’s oldest raw materials into the 21st century by redesigning the humble electric socket—and fashioning it out of discarded bones from the meat-processing industry. Swiss-Tunisian designer Souhaïb Ghanmi graduated from ECAL, Switzerland’s famed design school, last summer. For his diploma project, he designed Ecol, a range of electric sockets and light switches made…

In medical first, surgeons successfully transplanted pig heart into human patient. This is how they did it

In a medical first, doctors transplanted a pig heart into a patient in a last-ditch effort to save his life and a Maryland hospital said Monday that he’s doing well three days after the highly experimental surgery. While it’s too soon to know if the operation really will work, it marks a step in the decades-long quest to one day use animal organs for life-saving transplants. Doctors at the University of Maryland Medical Center say the transplant showed that a heart from a genetically modified animal can function in the human body without immediate rejection. The patient, David Bennett, a…

Global spread of autoimmune disease blamed on fast foods, others

More and more people around the world are suffering because their immune systems can no longer tell the difference between healthy cells and invading micro-organisms. Disease defences that once protected them are instead attacking their tissue and organs. Major international research efforts are being made to fight this trend – including an initiative at London’s Francis Crick Institute, where two world experts, James Lee and Carola Vinuesa, have set up separate research groups to help pinpoint the precise causes of autoimmune disease, as these conditions are known. “Numbers of autoimmune cases began to increase about 40 years ago in the…

A medical team has developed a Covid vaccine that could be a global game changer

A vaccine authorized in December for use in India may help solve one of the most vexing problems in global public health: How to supply lower-income countries with a Covid-19 vaccine that is safe, effective and affordable. The vaccine is called CORBEVAX. It uses old but proven vaccine technology and can be manufactured far more easily than most, if not all, of the Covid-19 vaccines in use today. "CORBEVAX is a game changer," says Dr. Keith Martin, executive director of the Consortium of Universities for Global Health in Washington, D.C. "It's going to enable countries around the world, particularly low-income…

Introducing the Bus-Train, the world’s first dual-mode vehicle

Japan recently unveiled the world’s first Dual-Mode Vehicle (DMV), a contraption that runs both on roads, like a bus, and on rails, like a train. The unique bus-train hybrid was unveiled last month, in the town of Kaiyo, Japan’s Tokushima Prefecture. The mini-bus-like contraption didn’t win anyone over with its looks, but it definitely made an impression in terms of practicality. It runs with normal rubber tires on the road, but when it needs to switch to train mode, a pair of metal wheels drop down from the vehicle’s underbelly. The front tires are lifted off of the track, while…

Do you have a cold, the flu or Covid-19? Experts explain how to tell the difference

Do you have a sore throat, a runny nose and muscle aches? It could be a common cold, a case of the flu — or Covid-19. The illnesses all share similar symptoms, sometimes making it hard to distinguish which is putting you under the weather. Case rates of Covid-19 have been on the rise as the Omicron variant has spread, but hospitalization numbers appear to be staying relatively low. For vaccinated people, evidence suggests that infection with this variant seems less likely to be severe, epidemiologist and former Detroit Health Department executive director, Abdul El-Sayed said. "The important thing to…

Artificial Intelligence can now craft original jokes - and that’s no laughing matter

Don’t you hate it,” says Jon the Robot, gesturing with tiny articulated arms at an expectant crowd, “when you’re trying to solve inverse kinematics equations to pick up a cup and then you get ‘Error 453, no solution found’?” The crowd laughs. “Don’t you hate that?” An experiment billed as a comedy act, Jon is the brainchild of Naomi Fitter, an assistant professor in the School of Mechanical, Industrial and Manufacturing Engineering at Oregon State University. The tiny android performs when a handler (who must also hold the mic) presses a button, then tells the same jokes in the same…

Obituary in advance: Blackberry will die on January 4th

Dear friends, we’re gathered here today to mourn the death of that once-beloved monarch of the mobile world: BlackBerry. And, yes, I realize that this is not the first time we’ve announced the death of the company or its devices (and, for reasons I’ll explain below, it likely won’t be the last) but this is a very definite ending for legacy BlackBerry hardware. As of January 4th, any phones or tablets running BlackBerry’s own software — that’s BlackBerry 7.1 or earlier, BlackBerry 10, or its tablet operating system BlackBerry PlayBook — will “no longer reliably function,” says the company. Whether…

What is Web3? And is it the next phase of the internet?

In theory, Web3 will allow you to go online without the need for search engines such as Google or social media like Facebook. But some say Web3 is under the control of the venture capital industry. Web3 has become the latest buzzword to get tech and cryptocurrency enthusiasts talking. While some are excited at what is being dubbed as the next phase of the Internet, others, including Elon Musk and Jack Dorsey, have voiced their concerns over it. But what is Web3 and can this decentralised vision of the Internet work? What is Web3? Put simply, Web3 is an umbrella…
