A research effort at Winship Cancer Institute recently identified a substance in orange lichen and rhubarb that has the potential to be used as a new anti-cancer drug. The substance, an orange pigment known as parietin or physcion, slows the growth and can even kill leukemia cells harvested from patients, without obvious toxic effects on human cells, the study authors report.
Used to make almost everything from skyscraper girders, automobiles, and appliances to thumb tacks and paper clips, steel is one of the world's most vital materials. While there's been a great amount of research invested into steel, most of it has concentrated on making various grades of steel, with little focus on the surface itself. Understanding that there's a great interest and need for steel surfaces that can stay clean and don't corrode under harsh biological conditions, a group of material scientists at Harvard have come up with a squeaky clean coating that does just that.
Researchers have discovered a new species of banana christened "nanensis", belonging to the Musa genus, sharing a place in the family Musaceae with more than 70 other species of bananas and plantains. It's scientific name honors the province of Nan where the type specimens were collected.
The world's oceans are sadly full of pollution, but now, you can help make a difference - while also looking dashing at the beach. A team of US researchers developed a very 3D printed chic bikini that helps clean up pollution from the water, while posing no risk to yourself.
Prosthetics has come a long way from its humble beginnings – the crude wooden legs of yore are a far cry from the technological marvels we can create to replace our limbs today. However, there is one thing that, with all our know-how, we haven’t yet been able to incorporate in them: a sense of touch. A research team from Stanford University aims to fix this shortcoming, and has developed technology that can “feel” when force is exerted upon it, then transmit the sensory data to brain cells – in essence, they’ve created an artificial skin.
Recent fossils unearthed in the Chinese province of Daoxian come to unravel the story of humanity’s spread as we know it today. The find consists of 47 teeth, belonging to modern humans, but what’s really important is their age – they have been dated to 80,000 years ago. This number doesn’t fit with the “Out of Africa” migration theory, holding that humans originate and have spread from the horn of the continent all around the world. The theory as we know it can’t explain human presence in the area for another 20,000 years.
Solar energy could be turned up a notch not by some exotic material or chip, but surprisingly by viruses. A team at MIT published a paper demonstrating how a genetically modified virus was used in a quantum system to transfer energy at double the speed and over a greater distance than even the best solar cells.
The greenest cars of the year... but why are there no Teslas?
Sometimes, it’s not just about the functionality of a prosthetic, but the hope and morale it brings. With this in mind, Open Bionics, a startup working to provide affordable, 3D printed prosthetic hands for amputees has revealed prosthetic arms for kids inspired from Iron Man, Frozen or Star Wars. Based in Bristol, UK, Open Bionics first began […]
Thor’s hammer was so magically heavy that only the worthy could lift it – and only Thor was worthy enough (or maybe … I don’t know, I haven’t watched the new Marvel movies). Electrical engineer Allen Pan, aka Sufficiently Advanced on YouTube,decided to replicate in his very own take on a “working” Mjolnir. The best way […]
Meet Napz - a biohacking device that improves your sleep quality and can even simulate lucid dreams.
A couple of days back we wrote that Tesla's new model S will be featuring an autopilot mode. The first reactions are amazing.
Combining machine learning and data analytics, Siri - the personal assistant for millions of Apple users - is a very powerful tool. Simply by voicing commands, Siri listens and obeys, whether you want to know how many calories are in your soda can or how many planes are flying above your head this very instant. But what if someone commanded Siri without your permission? A group of ethical French hackers recently showed it's possible to hijack Siri from up to 16 feet away using hardware that can fit in a backpack and satisfy any whim.
It's easy to assume that with economic gain comes happiness -- we live in capitalism, after all. But science comes to prove us all wrong yet again, and shows that the link between economics and happiness is much more complicated that we thought. Money can't buy happiness, it seems.
Chinese researchers discovered a chemical compound that works just as well as morphine -- without any of the negative side effects. The substance is derived from the venom of a centipede native to China. The discovery has huge medical applications, and could potentially reduce the country's military reliance on morphine for battlefield use.
A while ago, aerospace giant applied a patent for a most peculiar propulsion system that uses high power lasers to kick off a fusion reaction, akin to a small thermonuclear explosion. The energy released would be enough power spacecraft, rockets and even jetliners with tremendous thrust.
How do you understand the natural history of rocks and water on another planet when all you have are pictures? You do the math. Scientists have discovered how to use images of pebble shapes to estimate to estimate how far water may have moved them in ancient Martian riverbeds. These estimates enhance geographic information about […]
Bad news for us -- and fish.
Researchers stumbled upon a new tool to fight cancer in a rather unexpected place; while searching for a vaccine against malaria in pregnant women, a team of Danish scientists found that, simply put, armed malaria proteins are remarkably good at killing cancer cells. They hope to have a working prototype ready for human trials within four years' time. Their discovery has been published in the scientific journal Cancer Cell.
Earlier this week Tesla CEO Elon Musk took to twitter announcing a new software update for the Model S will come bundled with an autopilot feature for highway cruising. Previously, Tesla worked with a couple hundred early adopters, but come October 15th, everyone will be able to enjoy the spoils. The v7.0 autopilot features include auto-steering, lane change activated by the turn signal and auto-parking in parallel spaces.
The battlefield is shifting from trench soldiers to cyberspace and unmanned machines. As always, when a new technology of war is developed, a counter that levels the game isn't far behind. Business Insider reports three companies in the UK are working on a device that freezes drones in mid-air by flooding them with radio signals across all frequencies, similarly to how cell phone blockers work, or how Cooper in Interstellar captured a drone in his corn fields.
The rest of the 1% is made up of hallow tubes of nickel. So, this makes for a very rigid, but extremely lightweight material. Just look at the picture below of the lightest material in the world, called microlattice, balancing on a dandelion. You know the potential is huge.
The Sulaymaniyah Museum in Iraq uncovered 20 new lines of the Epic of Gilgamesh, the nearly 3000 years old Mesopotamian poem, considered to be one of the world's first great works of literature. They belong to a passage in which Gilgamesh enters a cedar forest and slays a demigod named Humbaba, with the setting and the demigod himself described differently and in more detail, writes Ted Mills for Open Culture.
With the variety of games available today varying from those designed to enhance mental fitness, solve real world problems all the way to ones meant for pure entertainment, they have diverse and profound effects on our brains. A new article published in the October 1st issue of Policy Insights from the Behavioral and Brain Sciences argues that the specific content, dynamics, and mechanics of individual games determine their effects on the brain and that the long-criticized action video games might have particularly positive benefits.
A newly founded artificial intelligence lab, called Vicarious, wants to build the world's first, unified artificial intelligence that can match human intelligence. This is not the first time we've heard companies or universities trumpet such ambitious goals, but considering who's backing the project I can only entertain the possibility Vicarious might just do it. Entrepreneurs with great vision and a track record of backing successful companies have all hopped aboard, like Elon Musk (SpaceX, Tesla), Mark Zuckerberg (Facebook), Peter Thiel (Paypal, founder of venture capital and hedge funds worth billions), Jerry Yang (Yahoo! founder), Jeff Bezos (Amazon founder) and more.
With Virtual Reality headsets coming out right around the corner, how can the gap with experience become more immersive? A couple of technologies on the horizon and currently under development may be the key.
Quantum computing is one of the future's transitional technologies destined to transform human society, along with advanced materials like graphene and metallic glass or advances in space propulsion. Imagine what the transition from vacuum tubes to transistors did for computing, scale that a couple of folds and you might somewhat be close to what quantum computers are capable of. Operations that today's supercomputers require days even weeks to crunch, would be completed immediately by leveraging the quantum weirdness that happens below the nano scale. All of this is theoretically possible - but in practice building a working quantum computer that doesn't disintegrate information has proven to be an immense challenge. We're still far from there, but advances reported by Australian researchers hint that quantum computers aren't a pipe dream.
The brain forms new thoughts using two adjacent brain regions that are the cornerstone of the process.
Despite decades worth of research, unbelievable computing power and sophisticated algorithms, one of today's best artificial intelligence can't score better than a four year old on a standard IQ test.
For most people listening to music or playing an instrument is a great way to relax, unwind, have fun, and express themselves. But not everybody is able to perceive, appreciate or memorize music, to sing or to dance. Monica is one such person, and to her, any kind of music is just a bunch of noise that makes her head ache and feel stressed.
Material scientists at Oxford University, collaborating with experts from Karlsruhe, Munster and Exeter, have developed the world's first light-based memory banks that can store data permanently. The device is build from simple materials, in use in CDs and DVDs today, and promises to dramatically improve the speed of modern computing.
Two drugs, currently prescribed to organ transplant patients to suppress their immune system after the procedure, show great promise as birth-control medicine for men, according to a study published in the journal Science.
While everyone from Google, to Tesla, to BMW is engineering driverless cars, gearing up for an impeding auto revolution, a Chinese company went directly for a niche market: driverless buses.
After the recent Volkswagen fiasco which revealed that their cars emit much more than they should (and claimed), a new study revealed that diesel cars made by Renault, Nissan, Hyundai, Citroen, Fiat, Volvo and many others also emit more.
When there's rain, let alone a storm, city streets form puddles and in some extreme cases get flooded. That's because concrete mostly keeps water out, and only a tiny volume gets absorbed. A company from the UK, however, has come up with such an innovative solution that it almost seems like magic were it not pure science at work. Namely, they came up with a new kind of concrete that allows more water to percolate through its gaps, so much that 1,056 gallons were gobbled up in under 60 seconds during a test. It all seems unreal - but it's as concrete as it gets.
The word on every tech executive's mouth today is data. Curse or blessing, there's so much data lying around - with about 2.5 quintillion bytes of data added each day - that it's become increasingly difficult to make sense of it in a meaningful way. There's a solution to the big data problem, though: machine learning algorithms that get fed countless variables and spot patterns otherwise oblivious to humans. Researchers have already made use of machine learning to solve challenges in medicine, cosmology and, most recently, crime. Tech giant Hitachi, for instance, developed a machine learning interface reminiscent of Philip K. Dick's Minority Report which can predict when, where and possibly who might commit a crime before it happens.
In front of hundreds of guests, Tesla's CEO, the ever resourceful Elon Musk, unveiled the company's new model: the Model X crossover. It's been a long heralded and waited vehicle, and it sure didn't disappoint. This beauty, all dressed in white, looks more like a bird than a car with its upward-opening "falcon doors". It also flies like one, reaching 0 to 60mph in 3.2 seconds making it the world's quickest SUV. Wait 'till the kids see it.
Despite manufacturers have tirelessly designed new types of razor blades for a cleaner shave, the process has stayed virtually unchanged for thousands of years. The difference between a modern razor blade and an ancient roman shaving knife isn't that large, on a fundamental level at least. This may set to change if the Skarp Laser Razor makes its way into the shaving kit market. The gadget is basically a high-tech razor - named so only by function - that uses a highly focused laser beam instead of a blade.
North Carolina State University researchers have succeeded in proving that the crystalline structure of a material can be formed by disorder at an atomic level and not chemical bonds, by creating the world's first entropy-stabilized alloy incorporating oxides.
Fewer materials in nature rival the toughness and resilience of a tooth or a seashell, and it's all due to their unique structure; viewed under powerful enough microscope, they reveal layers upon layers of micro-plates, perfectly aligned and fused together. Material scientists have long sought to produce something that imitates these structures, with comparable properties and complexity, but apart from nacre (mother-of-pearl) they've had very little success. Until now.
A 30KW high-power laser was demonstrated by Lockheed Martin after it was used to disable a vehicle more than a mile away. One of the great perks of laser weapons is their phenomenal accuracy. To showcase this, the weapon was directed specifically on the hood of the vehicle, where it fried the engine. The beam from the Advanced Test High Energy Asset, or ATHENA, is believed to be most powerful ever documented in a laser weapon.
A new paper published Thursday in Science looks at how climate change is (out of all things) making the tongue of some bumble bees shrink. Two species of alpine bumbles in the Rocky Mountains already show a decrease in tongue volume of nearly 25 percent in the last 40 years; and smaller tongues could spell big trouble for the flowers that rely on bumble bees for pollination.
I love disruptive technologies, and 3D printing is undoubtedly one of the leading such movements in the 21st century. This kind of tech will democratize manufacturing, moving it away from 3rd world sweatshops to your own garage. And no, you don't have to be a geek to own one. Ten years from now, it should be as easy to use and as widespread in homes as a regular ink printer. But for now, 3D printing is limited, particularly as far as electronics are concerned. Usually, you have to print the plastic parts, then order electronic parts like circuits, chips or motors, before finally assembling it all together yourself. You can't have a global manufacturing revolution if you need to be a lab wiz to print a new TV remote control to replace the one the dog just shred to pieces. But this is all changed. We're just now seeing the first steps that might one day lead people to print their own smartphones.
Humans are walking ecosystems. Each of us carries around about 100 trillion microbes in and on our bodies, which make up our microbiome. The quality of this bacterial community has a lot to say about our health and well-being. The blend of microbes is also surprisingly unique, which says a lot about who we are […]
Ian Lipkin, a virus hunter from Columbia University, along with fellow professors Thomas Briese and Amit Kapoor have designed a new system, known as VirCapSeq-VERT, that they claim can detect any known human virus in a blood sample.
Computer chips today have billions of tiny transistors just a few nanometers wide (a hair is 100nm thick), all crammed up in a small surface. This huge density allows multiple complex operations to run billions of times per second. This has been going on since the '60s when Gordan Moore first predicted that the number of transistors on a given silicon chip would roughly double every two years. So far, so good - Moore is still right! But for how long? There's only so much you can scale down a computer chip. At some point, once you cross a certain threshold, you pass from the macroworld into the spooky domain of quantum physics. Past this point, quantum fluctuations might render the chips useless. Moore might still be right, though. Or he could be wrong, but in a way that profits society: computer chips could increase in computer power at a far grater pace than Moore initially predicted (if you still keep Moore's law but replace transistors with the equivalent computing power). This doesn't sound so crazy when you factor in quantum computers or, more practical, a 3D computer architecture demonstrated by a team at Stanford University which crams both CPU and memory into the same chip. This vastly reduces the "commuting time" electrons typically have to go through while traveling through conventional circuits and makes them more efficient. Such a 3D design could make a chip 1,000 faster than what we typically see today, according to the researchers.
Drones are often feared as instruments of destruction, and as John Oliver pointed out, in some parts of the world, people fear blue skies because that’s when the drones strike. But this technology isn’t only used to destroy – it can also be used to create, as demonstrated by these very efficient quadrocopters building a rope […]
Researchers from the University of Washington and the Allen Institute for Artificial Intelligence (AI2) have developed a computer software that scored 49% on high-school geometry SAT tests - an average score for a human, but a great one for current AIs.
The Øresund bridge is a wonder of engineering, and one of the coolest engineering accomplishments on the planet.
The human inovation process is more of a slow, steady climb than a sum of great leaps, a new University of Reading study shows. Our minds tend to innovate by adding small improvements through trial and error report the scientists, who studied one of the most important cultural events in human history - the migration of the Bantu-speaking farmers in Africa some 5,000 years ago. Mark Pagel, Professor of Evolutionary Biology at the University, led the study.
