Though betavoltaics – battery technology that employs radiation as a means of power generation – has been around since the 1950s, developments thus far haven’t been the most promising. This may set to change after researchers at University of Missouri reported they’ve devised a nuclear-assisted battery, which works in a watery environment, that both lasts longer […]
Neuroscientists at University of Western Ontario in London, Canada found that a man who was thought to be living in a vegetative state for almost twenty years showed response when an Alfred Hitchhock movie was played in the background. The findings suggest that doctors might want to explore more methods to determine whether or not a […]
About 1.4% of the world’s population today is speech impaired, due to conditions such as Amyotrophic lateral sclerosis (ALS), locked-in syndrome (LIS), Encephalopathy (SEM),Parkinson’s disease, and paralysis. Imagine all the people living in Germany today were unable to speak and you’ll come to realize just how far reaching this condition is. So, aside for those being […]
Researchers at the University of Stanford and the University of California, Berkeley just presented a tiny radio, so small it’s the size of an ant, that could very well change the way we interact with technology in the future. What makes the device truly incredible is its ability to power itself without using an external power […]
People who frequently smoke marijuana may use the drug to cope with negative emotions. This sort of association makes people more inclined to abuse marijuana and makes it harder to quit, according to a new study published in the Journal of Studies on Alcohol and Drugs. Lighting up to fight bad vibes, but is it worth it? […]
In the 1950s rainforests covered 14% of the earth’s land surface; now they cover a mere 6% and experts estimate that the last remaining rainforests could be consumed in less than 40 years. It’s believed that deforestation accounts for about 20% of global emissions of CO2, because of the a reduced carbon storage capacity. Yet there […]
Stanford researchers traced back methane leaks from contaminated drinking water in Pennsylvania and Texas to shale gas wells. However, they note that they did not find a link between the contamination and the technique used to drill for shale gas itself, called hydraulic fracturing or more commonly known as fracking. Instead, the researchers concluded that […]
The world is currently on a downward spiral, risking reaching a point of no return where global warming can no longer be reversed – not in due time at least. We’re already 50ppm of CO2 (parts per million) over the 350ppm average atmospheric CO2 concentration, considered by leading experts the carbon stabilizing threshold. It’s increasingly […]
A new method of producing hydrogen has been reported by researchers at University of Glasgow that’s 30 times faster than current state-of-the-art methods, providing yet another advance that might one day lead to a sustainable hydrogen based economy. There’s only so much that renewable energy can grow with today’s infrastructure due to base load considerations. […]
Researchers at Johns Hopkins Universityin Baltimore used psilocybin, the active ingredient in magic mushrooms, in a novel treatment that helped a dozen people quit smoking. The findings adds to growing body of evidence that suggests psilocybin, combined with counseling, can be a highly effective tool against addiction and depression. Volunteers were given each a 20 milligram pill […]
Most quantum research is focused on studying interactions between light and atoms, a field known as quantum optics. Researchers at Chalmers University of Technology in Sweden took an alternate route and demonstrated for the first time that acoustic waves could be used to communicate with an atom. The findings could provide an important stepping stone for […]
The most balanced and thoughtful Tesla biography to date. With this book, Carlson shines new light on Tesla's legacy.
U.N. scientists released a report in which they conclude man-made carbon emissions released between 2012 and 2013 were higher than in any other year since 1984. If this trend is set to continue, the planet will reach a tipping point where global warming will become an irreversible phenomenon that could cause enough sea level rise, drought, and severe […]
Since it was first introduced decades ago, mass spectrometry has proved to be an invaluable tool for analyzing the chemical makeup of foods, pharmaceuticals, forensic remains and so on. The equipment, however, is extremely bulky, expensive (in the hundreds of thousands range) and a sample might take days of back and forth analysis before results […]
In a lifetime of seeing thousands of patients, a doctor will hear all sorts of crazy stories and bizarre cases. A recent thread on reddit asked doctors from the community to share some of their wackiest stories and boy were there some. Here are just a few of them: Aaaaand some bonus stories without captioned images: […]
One of the most famous chemistry experiments of the last century was the ‘primordial soup’ project initiated by Stanley Miller. The chemist wanted to see what would happen if you mixed methane, ammonia and hydrogen – all substances readily available on Earth before life began – and zapped them with electricity, to create a phenomenon analogous to […]
I’m not sure what’s on with Stephen Hawking and his pessimistic view of the world. He’s been known for audacious, panic-inflicting claims like the world is going to be destroyed either by aliens or artificial intelligence, all if we don’t destroy ourselves in the meantime since humans only have 1,000 years left on this planet […]
Patients with hemophilia are often forced to live in a bubble. Even the smallest cut can cause significant blood loss, and often times these minor accidents can also cause internal bleeding that affects organs and threatens life. Some treatments have proven effective at keeping hemophilia at bay, at least to a degree, yet some groups […]
In an attempt to further out understanding of cell deformation and mechanics, researchers at the Technische Universität München (TUM) have built an artificial cellular model that can change its shape and move on its own. Cells are complex biological objects that exhibit sophisticated metabolic functions. Primordial cells, however, were much simpler in design: just a […]
Cellular biology can be breathtakingly exciting. Just imaging peering through the absolute tiniest forms of life – a whole different universe in itself! Many times, in this cellular universe, you witness chaos, but here’s where Brazilian multidisciplinary artist Vik Muniz and self-described “bacteria enthusiast” Tal Danino come in. The two paired and launched an ambitious […]
Like most developing nations, India is burning a lot of coal to catch ground. As always the case with compromises such as these, economic growth comes at the expense of the environment. Pollution in Delhi, the capital, has reached levels comparable to Beijing, which is when you know you’ve hit a new low. A new study […]
Some atoms are more stable than others, and the same goes for their isotopes – elements that have the same number of protons in the nucleus, but different number of neutrons. For instance, some decay in a trillionth of a second, while others can live on for billions of years. Actually, using isotopes (thorium and […]
The Environmental Protection Agency (EPA) recently issued the first ever permit that will allow a coal plant to store some of its carbon emissions underground, as a means of mitigating global warming. The idea has been around since George W. Bush, but time and time again its been scrapped largely for economic considerations. Ten years later, FutureGen […]
Swiss scientists from the University of Bern demonstrated a new device that essentially generates electrical power from the mechanical energy of heartbeats.
A group of neuroscientists have achieved what some might believe strictly belongs to the realm of science fiction – they’ve successfully transmitted a message relayed by the brain of a person to another directly; no voice, no video, no sound, no text. The information was fed directly to the brain. If that wasn’t enough, the […]
Our sun is but a tiny speck of light among billions, part of the spiral galaxy we familiarly call the Milky Way. That in itself makes us puny humans feel extremely humble, but things get really out of proportion when you zoom out. Galaxies on their own turn congregate in the hundreds or even thousands, […]
Researchers at University of Texas at Arlington conducted tests on more than 100 water wells in Texas and found 30% of these contained ‘alarming’ amounts of arsenic, enough to be considered carcinogenic and seriously threatening human health. These contaminated wells were found in the vicinity of known fracking sites and prior to drilling these were found […]
Globalization certainly has its ups: new markets, free trade, travel or economic growth (especially for developing nations). It's this latter aspect of globalization that might be the dominant factor that's wiping out languages from the face of the world, according to a study by researchers at University of Cambridge.
A recent study that assessed coffee and tea consumption habits of a whooping 131 000 people from France found that tea reduces non-cardiovascular mortality (non-CV) by 24%. Far from it, the same can’t be said about drinking coffee: consumers had a higher CV risk profile than non-drinkers, particularly for smoking. Overall there’s a tendancy to have a higher risk […]
Feynman was at times called "The Great Explainer" because of his skill at making complex subjects accessible to students, and while still a professor at Caltech he released his now famous Feynman Lectures on Physics. The three-volume collection has since become the most popular physics text book. Now, the whole collection is available for free, online for your personal consideration.
DARPA just announced the launch of a new extremely exciting program: Atoms to Product (A2P). The aim is to develop a suit of technologies that will allow manufacturing of products from the nanoscale up to what we know as ‘life size’. The revolutionary miniaturization and assembly methods would work at scales 100,000 times smaller than current state-of-the-art technology. […]
NASA reports significant quantities of ozone-depleting chemicals are still leaching into the atmosphere despite an international ban signed by all the world's governments thirty years ago.
Researchers at Swansea University, UK and Uppsala University in Sweden built a mathematical model that explains how one single sheepdog can round up herds made of up to 100 sheep. Their conclusion suggests that the dog needs only to follow two simple mathematical rules.
Either when someone’s late for a date or you need to queue in line, our patience becomes tested. Some people handle the waiting better than others, leading us to the idea that patience is a virtue that differs from person to person. But what is it exactly that helps us remain patient, and why do […]
From the tropics to the poles, bird populations all over the world are facing a sharp decline, cornered by climate change and exposure to man-made biochemicals, namely pesticides. According to to BirdLife International, one in eight species (more than 1,300 species) of birds are under serious threat of becoming extinct. The list includes iconic birds of pray and song like eagles, vultures, swifts or swallows, but also seabirds like sandpipers, pelicans or storks.
For billions of years, nature has been harnessing the energy from the sun through photosynthesis. This way, plants, algae and cyanobacteria use sunlight to split water and produce energy-rich chemical compounds from carbon dioxide (CO2). This energy is then transferred to animal that eat these plants, and animals that eat plant-eating animals, including us humans. It’s […]
While most of the hype is centered around biotech efforts that try to engineer human organs from scratch in the lab, a better idea might be to grow human-compatible organs in foreign hosts. Researchers at the National Heart, Lung and Blood Institute (NHLBI) of the National Institutes of Health genetically modified pig hearts with some human […]
A while ago I wrote about the disheartening status quo of energy today: frack now, ask questions later. In the article, I argue that there’s a disproportion between the amount of hydraulic fracturing (9 out of 10 wells in the US are fracking wells) and the number of research articles that discuss the bio impact […]
Listening to loud music has been shown time and time again to affect hearing in a negative way. The damage becomes more pronounced with age, leading to difficulties in understanding speech. A new analytic study by researchers at University of Leicester examined the cellular mechanisms that underlie hearing loss and tinnitus triggered by exposure to loud […]
A study by researchers at Harvard University found that children from a tender age have an advanced idea of fairness and are willing to step forward and pay a personal price to intervene a situation they perceive as an unfair. This decision is group-biased dominant in children aged six or less, but those aged eight or more were found to intervene in unfair situation and stop any selfish behavior, whether or not the victim was a member of their group.
Ten years ago, the European Space Agency launched the Rosetta probe tasked to orbit a comet for the very first time and study it up close with unprecedented detail. Six billion miles later, the probe reached its target, the four-kilometer wide 67P comet, and has beamed back some of the most breathtaking images of a […]
Lead-acid car batteries used to be the norm, but luckily we’re seeing a massive shift towards more efficient and environmentally friendly alternatives like lithium-ion. Still, there are fleets of hundreds of millions of cars that still employ these archaic and toxic batteries. Typically, manufacturers try to have car owners bring their old lead-acid batteries, which […]
Researchers at the Max Planck Institute of Immunobiology and Epigenetics (MPI-IE) re-activated the expression of an ancient gene in mice. To their surprise, the gene in question which is dormant in all mammalian species caused the mice to develop fish-like thymus. The thymus is an organ of paramount importance to the adaptive immune system, but in […]
A parasitic plant called the dodder, which essentially acts like a 'vampire' upon its unsuspecting prey. A new research found the dodder actually communicates using DNA with its host in order to lower its defenses. A true vampire to the end - it needs an invitation to step in.
Early modern human populations were culturally diverse and sometimes exchanged tools helped by river networks in a then savanna rich Sahara, according to the biggest ever comparative study of stone tools dating to between 130,000 and 75,000 years ago. At least fourdistinct populations, each relatively isolated from each other, have been identified as possessing distinct cultural practices.
A first of its kind study conducted at the University of Colorado Denver looked at how city design affects populace health. Older cities, initially built for pedestrian traffic in mind were found to harbor less cases of diabetes and other diseases than those with broader streets and fewer intersections. While some people can stay healthy and stick to exercising habits no matter where they live in, the study suggests that in general cities which are optimized for vehicle traffic discourage walking and other healthy activities.
In a breakthrough in robotics, researchers have programmed a swarm consisting of a whooping 1,024 members which can assemble in programmable 2-D shapes. The demonstration might provide insights in how natural self-assembling swarms operate, like ants who join up to form bridges for the good of the colony.
Scientists introduced Clostridium novyi, a bacteria that causes mild illnesses in humans that typically lurks inside the soil and feces, in cancer tumors and found that these shrank and some cases were destroyed completely. The research suggests that bacteria, when engineered to reduce toxicity, can be a viable fighting tool against cancer, one with less destructive […]
We’ve covered quite a bit the recent developments involving perovskite as an extremely promising light-to-energy conversion semiconductor. Now, researchers at University of Cambridge, University of Oxford, and Ludwig-Maximilians-Universität are performing research on perovskite-based devices that work the other way around by emitting light. Their research has turned out promising results that suggest high-brightness LEDs, manufactured at […]
