“I didn’t think I would be emotional about this.”

It’s not just humans that use prosthetic limbs—wounded or disabled animals can benefit from them, too. In the past, we’ve reported on cats, dogs, and even an elephant who have been fitted for prosthesis. The latest creature who’s now learning to walk on an artificial foot is an adorable duck named Waddles.

Waddles was born with a deformed leg, but his adoptive owner Ben Weinman wanted to help him live a better life. He contacted Derrick Campana, a Certified Pet Prostheticist at Bionic Pets who made a 3D-printed prosthetic leg and foot.

A clip from the NatGeo Wild series, The Wizard of Paws, was recently shared online, revealing the heartwarming moment when Waddles was fitted with his new leg. At first, he’s not quite sure what to make of it, but after a little encouragement from Weinman and Campana, he starts happily toddling along on both feet.

Discovery in Salamanders by James W. Godwin, Ph.D., brings science closer to the development of regenerative medicine therapies.

Many salamanders can readily regenerate a lost limb, but adult mammals, including humans, cannot. Why this is the case is a scientific mystery that has fascinated observers of the natural world for thousands of years.

Now, a team of scientists led by James Godwin, Ph.D., of the MDI Biological Laboratory in Bar Harbor, Maine, has come a step closer to unraveling that mystery with the discovery of differences in molecular signaling that promote regeneration in the axolotl, a highly regenerative salamander, while blocking it in the adult mouse, which is a mammal with limited regenerative ability.

Bill Gates isn’t going to use it to track you.

Your next doctor’s appointment could soon become much more informative thanks to new microchips the size of dust mites, only visible beneath a microscope.

Picture this: Your surgeon wants to continuously monitor your lungs prior to a procedure to ensure your respiratory system is strong enough to deal with anesthesia. So, a technician uses a hypodermic needle to inject a few small microchips into your body. Then, they use an ultrasound machine to communicate with the chips, which show your lungs are primed for the operation. Your subsequent surgery is a breeze.

Google wants to train you to become a UX designer in 6 months — without a college degree. Here’s how to make the most of the certificate program and potentially make $84000 a year.

The US unemployment rate sits at 6.7%. Thanks to COVID-19, millions of Americans are still out there looking for not just a new job but also an entire new career path.

Tech fields like UX design, data analysis, and project management are looking for promising candidates, and Google announced a new career-certificate program to help make them more accessible last summer.

The forthcoming program, called Google Career Certificates, will be taught online by Google staff, take six months to complete, and be treated as the equivalent of a relevant college degree by the search giant, according to Kent Walker, Google’s senior vice president of global affairs.

Experts share their best tips on using bootcamps like Google’s to launch a career in emerging tech fields.

Circa 2011

It sounds like a late-night infomercial: Kill germs and clean surfaces with nothing more than water and a few volts of electricity! Pay pennies a gallon! Strong enough to kill germs but gentle on your skin!

The use of electricity and water to clean and disinfect has been embraced by some food and hospitality businesses looking to save money and go green by swapping out conventional products.

At busy Whole Foods on Manhattan’s Union Square, workers keep battery-operated spray bottles designed to keep surfaces clean with water packing an electrical charge. Also available are electrolyzed oxidizing water products, or EO water, which are cleaning systems that use salt and electricity to create solutions for cleaning kitchens, prison floors and hotel rooms.

When you put these three factors together—the bounty of technological advances, the compressed restructuring timetable due to covid-19, and an economy finally running at full capacity—the ingredients are in place for a productivity boom. This will not only boost living standards directly, but also frees up resources for a more ambitious policy agenda.

AI and other digital technologies have been surprisingly slow to improve economic growth. But that could be about to change.

COVID 19 pandemic, automation and 6G could end the metropolitan era from building high sky scrapers for companies. Companies can operate like a network from home to home without going to office. This will help a lot to bring down Urban Heat Islands and make our cities more efficient in transportation and communication to send the data even faster.

Tom Marzetta is the director of NYU Wireless, New York University’s research center for cutting-edge wireless technologies. Prior to joining NYU Wireless, Marzetta was at Nokia Bell Labs, where he developed massive MIMO. Massive MIMO (short for “multiple-input multiple-output”) allows engineers to pack dozens of small antennas into a single array. The high number of antennas means more signals can be sent and received at once, dramatically boosting a single cell tower’s efficiency.

Massive MIMO is becoming an integral part of 5G, as is an independent development that came out of NYU Wireless by the center’s founding director Ted Rappaport: Millimeter waves. And now the professors and students at NYU Wireless are already looking ahead to 6G and beyond.

Marzetta spoke with IEEE Spectrum about the work happening at NYU Wireless, as well as what we all might expect from 6G when it arrives in the next decade. The conversation below has been edited for clarity and length.

A team of researchers from the University of Sydney, the ARC-Plant Protection Research Institute and York University, has found that workers in a species of honeybee found in South Africa reproduce by making near-perfect clones of themselves. In their paper published in Proceedings of the Royal Society B, the group describes their study of the bees and what they learned about them.

Prior research has found that some creatures reproduce through parthenogenesis, in which individuals reproduce without mating. This form of reproduction has the advantage of not wasting time and energy on mating and the gene pool remains undiluted. The downside, of course, is loss of genetic diversity, which helps species survive in changing conditions. Prior research has also shown that for most species, parthenogenesis is a less-than-perfect way to produce . This is because some tiny bit of genetic material is generally mixed wrong—these mistakes, known as recombinations, can lead to birth defects or non-productive eggs. In this new effort, the researchers have found a kind of honeybee that has developed a way to avoid recombinations.

The researchers found that South African Cape honeybee queens reproduce sexually, but the workers reproduce asexually. They then conducted a small experiment—they affixed tape to the reproductive organs of a queen, preventing males from mating with her, and then allowed both her and the worker bees in the same hive to reproduce asexually. They then tested the degree of recombination in both. They found that offspring of the queen had approximately 100 times as much recombination as the worker bees. Even more impressive, the offspring of the worker bees were found to be nearly identical clones of their parent. More testing showed that one line of worker bees in the hive had been cloning themselves for approximately 30 years—a clear sign that workers in the hive were not suffering from birth defects or an inability to produce viable offspring. It also showed that they have evolved a means for preventing recombination when they reproduce.

A team of scientists at the University of Sussex have for the first time built a modular quantum brain scanner, and used it to record a brain signal. This is the first time a brain signal has been detected using a modular quantum brain sensor anywhere in the world. It’s a major milestone for all researchers working on quantum brain imaging technology because modular sensors can be scaled up, like Lego bricks. The team have also connected two sensors like Lego bricks, proving that whole-brain scanning using this method is within reach—as detailed in their paper, which is published today in pre-print. This has not been possible with the currently commercially available quantum brain sensors from the United States.

These modular devices work like play bricks in that they can be connected together. This opens up the potential for whole– scanning using quantum technology, and potential advances for neurodegenerative diseases like Alzheimer’s.

The device, which was built at the Quantum Systems and Devices laboratory at the university, uses ultra-sensitive quantum to pick up these tiniest of magnetic fields to see inside the brain in order to map the neural activity.

Google has helped create the most detailed map yet of the connections within the human brain. It reveals a staggering amount of detail, including patterns of connections between neurons, as well as what may be a new kind of neuron.

The brain map, which is freely available online, includes 50000 cells, all rendered in three dimensions. They are joined together by hundreds of millions of spidery tendrils, forming 130 million connections called synapses. The data set measures 1.4 petabytes, roughly 700 times the storage capacity of an average modern computer.

The data set is so large that the researchers haven’t studied it in detail, says Viren Jain at Google Research in Mountain View, California. He compares it to the human genome, which is still being explored 20 years after the first drafts were published.
