D Doctors have taken a major step towards curing the most common form of blindness in the UK – age-related macular degeneration. Douglas Waters, 86, could not see out of his right eye, but “I can now read the newspaper” with it, he says. He was one of two patients given pioneering stem cell therapy […]

The ability to sense the spatial position and movements of one’s own body (kinesthetic sense) is critical for limb use. Because prostheses do not provide physical feedback during movement, amputees may not feel that they are in control of their bodily movements (sense of agency) when manipulating a prosthesis. Marasco et al. developed an automated […]

Household cleaners, paints and perfumes have become substantial sources of urban air pollution as strict controls on vehicles have reduced road traffic emissions, scientists say. Researchers in the US looked at levels of synthetic “volatile organic compounds”, or VOCs, in roadside air in Los Angeles and found that as much came from industrial and household […]

With two billion people worldwide lacking access to clean and safe drinking water, joint research by Monash University, CSIRO and the University of Texas at Austin published today in Sciences Advances may offer a breakthrough new solution. It all comes down to metal-organic frameworks (MOFs), an amazing next generation material that have the largest internal […]

Geologists matching rocks from opposite sides of the globe have found that part of Australia was once attached to North America 1.7 billion years ago. Researchers from Curtin University in Australia examinedrocks from the Georgetown region of northern Queensland. The rocks — sandstone sedimentary rocks that formed in a shallow sea — had signatures that […]

Plants lack eyes and ears, but they can still see, hear, smell and respond to environmental cues and dangers—especially to virulent pathogens. They do this with the aid of hundreds of membrane proteins that can sense microbes or other stresses. Only a small portion of these sensing proteins have been studied through classical genetics, and […]

Physicists have experimentally demonstrated an information engine—a device that converts information into work—with an efficiency that exceeds the conventional second law of thermodynamics. Instead, the engine’s efficiency is bounded by a recently proposed generalized second law of thermodynamics, and it is the first information engine to approach this new bound. The results demonstrate both the […]

a new study in IEEE Transactions on Intelligent Transportation Systems mathematically models the implications of the larger problem: You’re not keeping the right distance from the car behind you. That may seem counterintuitive, since you don’t have much control over how far you are from the car behind you—especially when that person is a tailgater. […]

The recent news that stents inserted in patients with heart disease to keep arteries open work no better than a placebo ought to be shocking. Each year, hundreds of thousands of American patients receive stents for the relief of chest pain, and the cost of the procedure ranges from $11,000 to $41,000 in US hospitals. […]

Back in 2014, scientists at the Scripps Research Institute in California reported that they’d engineered bacteria whose DNA used a whole new pair of letters, nicknamed X and Y. That same team now reports that they’ve gotten the bacteria to actually use these new letters. The biological possibilities, as a result, now seem endless.“The resulting […]

A group of physicists from Russia, Sweden and the U.S. has demonstrated a highly unusual optical effect. They managed to “virtually” absorb light using a material that has no light-absorbing capacity. The research findings, published in Optica, break new ground for the creation of memory elements for light. The absorption of electromagnetic radiation, including light, […]

Scientists for the first time have tried editing a gene inside the body in a bold attempt to permanently change a person’s DNA to cure a disease. The experiment was done Monday in California on 44-year-old Brian Madeux. Through an IV, he received billions of copies of a corrective gene and a genetic tool to […]

Welcome to the website of The Atlas of the underworld – the first complete mapping of subducted plates in the Earth’s mantle and their geological interpretation.The Earth’s rigid outer shell – the lithosphere – is broken into plates that move relative to one another along discrete plate boundaries – ridges, transforms, and subduction zones. At […]

A large, 18-country study may turn current nutritional thinking on its head. The new research suggests that it’s not the fat in your diet that’s raising your risk of premature death, it’s too many carbohydrates — especially the refined, processed kinds of carbs — that may be the real killer. The research also found that […]

Scientists hope they have found a drug to stop all neurodegenerative brain diseases, including dementia.In 2013, a UK Medical Research Council team stopped brain cells dying in an animal for the first time, creating headline news around the world.But the compound used was unsuitable for people, as it caused organ damage.Now two drugs have been […]

Here we experimentally demonstrate that polarization quantum states including general qubits of single photon and entangled states can survive well after travelling through seawater. We perform experiments with seawater collected over a range of 36 kilometers in the Yellow Sea. For single photons at 405 nm in a blue-green window, we obtain an average process […]

A small clinical trial conducted at the Murdoch Children’s Research Institute has led to two-thirds of children treated with an experimental immunotherapy treatment being cured of their allergy. Importantly, this desensitisation to peanuts persisted for up to four years after treatment. […] Forty-eight children were enrolled in the PPOIT trial and were randomly given either […]

https://www.theverge.com/2016/10/5/13162476/nobel-prize-chemistry-tiny-machine-molecules-nanocar-stoddart-ferringa-sauvage This year’s Nobel Prize in Chemistry has been awarded to three scientists who figured out how to build tiny machines out of molecules. The machines, which include a nano-sized car, are invisible to the human eye and have important implications in medicine and other fields. The researchers — Jean-Pierre Sauvage, J. Fraser Stoddart, and Bernard Feringa […]

Historically, it is believed that crystalline uraninite, produced via the abiotic reduction of hexavalent uranium (U(VI)) is the dominant reduced U species formed in low-temperature uranium roll-front ore deposits. Here we show that non-crystalline U(IV) generated through biologically mediated U(VI) reduction is the predominant U(IV) species in an undisturbed U roll-front ore deposit in Wyoming, […]

Researchers at the University of Waterloo have been able to capture the first composite image of a dark matter bridge that connects galaxies together. The scientists publish their work in a new paper in Monthly Notices of the Royal Astronomical Society. The composite image, which combines a number of individual images, confirms predictions that galaxies […]

Researchers have discovered that the lungs play a far more complex role in mammalian bodies than we thought, with new evidence revealing that they don’t just facilitate respiration – they also play a key role in blood production. In experiments involving mice, the team found that they produce more than 10 million platelets (tiny blood […]

Imagine a liquid that could move on its own. No need for human effort or the pull of gravity. You could put it in a container flat on a table, not touch it in any way, and it would still flow. Brandeis researchers report in a new article in Science that they have taken the […]

The human brain reaches its adult volume by age 10, but the neurons that make it up continue to change for years after that. The connections between neighboring neurons get pruned back, as new links emerge between more widely separated areas of the brain. Eventually this reshaping slows, a sign that the brain is maturing. […]

Fillings could be consigned to history after scientists discovered that a drug already trialled in Alzheimer’s patients can encourage tooth regrowth and repair cavities. Researchers at King’s College London found that the drug Tideglusib stimulates the stem cells contained in the pulp of teeth so that they generate new dentine – the mineralised material under […]

Today, the University of California at Berkeley has deleted 20,000 college lectures from its YouTube channel. Berkeley removed the videos because of a lawsuit brought by two students from another university under the Americans with Disabilities Act. We copied all 20,000 and are making them permanently available for free via LBRY. This makes the videos […]
