Team that invented way to enlarge objects now invents method to shrink objects to the nanoscale, decreasing their volume 100x

MIT researchers have invented a way to fabricate nanoscale 3-D objects of nearly any shape. They can also pattern the objects with a variety of useful materials, including metals, quantum dots, and DNA. “It’s a way of putting nearly any kind of material into a 3-D pattern with nanoscale precision,” says Edward Boyden, an associate […]

Scientists identify vast underground ecosystem containing billions of micro-organisms

The Earth is far more alive than previously thought, according to “deep life” studies that reveal a rich ecosystem beneath our feet that is almost twice the size of all the world’s oceans. Despite extreme heat, no light, minuscule nutrition and intense pressure, scientists estimate this subterranean biosphere is teeming with between 15bn and 23bn […]

Reports of First Genetically Enhanced Babies Spark Outrage

Twin girls born earlier this month had their DNA altered to prevent them from contracting HIV, according to an Associated Press report. If confirmed, the births would signify the first gene-edited babies in human history—a stunning development that’s sparking an outcry from scientists and ethicists. Professor He Jiankui of Shenzhen, China, made the announcement earlier […]

Inside Hurricane Maria in 360°

Two days before Hurricane Maria devastated Puerto Rico, the NASA-Japan Global Precipitation Measurement Core Observatory satellite captured a 3-D view of the storm. At the time Maria was a Category 1 hurricane. The 3-D view reveals the processes inside the hurricane that would fuel the storm’s intensification to a category 5 within 24 hours. For […]

Researchers Created ‘Quantum Artificial Life’ For the First Time

For the first time, an international team of researchers has used a quantum computer to create artificial life—a simulation of living organisms that scientists can use to understand life at the level of whole populations all the way down to cellular interactions. With the quantum computer, individual living organisms represented at a microscopic level with […]

‘Real’ fake research hoodwinks US journals, shows bias against white men gets published regardless of content

Three US researchers have pulled off a sophisticated hoax by publishing fake research with ridiculous conclusions in sociology journals to expose what they see as ideological bias and a lack of rigorous vetting at these publications. Seven of the 20 fake articles written by the trio were accepted by journals after being approved by peer-review […]

Quantum chicken-or-egg experiment blurs the distinction between before and after

In the everyday world, events occur in a definite order—your alarm clock rings before you wake up, or vice versa. However, a new experiment shows that when fiddling with a photon, it can be impossible to say in which order two events occur, obliterating our common sense notion of before and after and, potentially, muddying […]

On Highway Noise Barriers, the Science Is Mixed. Are There Alternatives?

Engineers and acousticians have known for years that the sound barriers bracketing America’s urban and suburban highways are only marginally useful, and that a variety of better technologies could be developed. The problem: Nobody has an incentive to get them on the road. “Walls are not a very effective solution,” said Robert Bernhard, vice president […]

New ‘e-dermis’ brings sense of touch, pain to prosthetic hands

a team of engineers at the Johns Hopkins University that has created an electronic skin. When layered on top of prosthetic hands, this e-dermis brings back a real sense of touch through the fingertips. “After many years, I felt my hand, as if a hollow shell got filled with life again,” says the anonymous amputee […]

Paper straw factory to open in Britain as restaurants ditch plastic

No paper straws have been made in Britain for the last several decades. But that is about to change as a group of packaging industry veterans prepare to open a dedicated paper straw production line in Ebbw Vale, Wales, making hundreds of millions of straws a year for McDonald’s and other food companies as they […]

Climate Change Can Be Reversed by Turning Air Into Gasoline

A team of scientists from Harvard University and the company Carbon Engineering announced on Thursday that they have found a method to cheaply and directly pull carbon-dioxide pollution out of the atmosphere. […] the new technique is noteworthy because it promises to remove carbon dioxide cheaply. As recently as 2011, a panel of experts estimated […]

Memory Transferred between Snails using RNA, Challenging Standard Theory of How the Brain Remembers

UCLA neuroscientists reported Monday that they have transferred a memory from one animal to another via injections of RNA, a startling result that challenges the widely held view of where and how memories are stored in the brain. The finding from the lab of David Glanzman hints at the potential for new RNA-based treatments to […]

Forget the Double Helix—Scientists Discovered a New DNA Structure Inside Human Cells

For the first time ever, scientists have identified the existence of a new DNA structure that looks more like a twisted, four-stranded knot than the double helix we all know from high school biology. The newly identified structure, detailed Monday in the journal Nature Chemistry, could play a crucial role in how DNA is expressed. […]

Researchers are keeping pig brains alive outside the body

In a step that could change the definition of death, researchers have restored circulation to the brains of decapitated pigs and kept the reanimated organs alive for as long as 36 hours. The feat offers scientists a new way to study intact brains in the lab in stunning detail. But it also inaugurates a bizarre […]

Properly random random number generator generated

From dice to modern electronic circuits, there have been many attempts to build better devices to generate random numbers. Randomness is fundamental to security and cryptographic systems and to safeguarding privacy. A key challenge with random-number generators is that it is hard to ensure that their outputs are unpredictable1,2,3. For a random-number generator based on a […]

The Interstitium Is Important, But Don’t Call It An Organ (Yet)

In brief: It’s called the interstitium, or a layer of fluid-filled pockets hemmed in by collagen and it can be found all over our bodies, from skin to muscles to our digestive system. The interstitium likely acts as a kind of shock absorber for the rest of our interior bits and bobs and the workings of […]

Here’s What Protects Shipwrecks From Looters and Hacks

On May 25, 1798, the HMS DeBraak was entering Delaware Bay when a squall struck without warning. The British ship that originally belonged to the Dutch capsized and sank, taking 34 sailors and a dozen Spanish prisoners down with it. Rumored to contain a hoard of gold and jewelry, the DeBraak became a popular target […]

Stem cell therapy cures most common cause of blindness in UK

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 […]

Illusory movement perception improves motor control for prosthetic hands

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 […]

Cleaning products as large a source of urban air pollution as cars

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 […]

1.7-Billion-Year-Old Chunk of North America Found Sticking to Australia

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 […]

Breakthrough study shows how plants sense the world

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 […]
