Reverse osmosis membranes with tunable thickness

Currently, more than 300 million people around the world rely on desalinated water for part or all of their daily needs. That demand will only grow with larger populations and improved standards of living around the world. Accessing the oceans for drinking water, however, requires desalination technologies that are complicated ... Read More »

Under pressure, hydrogen offers a reflection of giant planet interiors

Lab-based mimicry allowed an international team of physicists including Carnegie’s Alexander Goncharov to probe hydrogen under the conditions found in the interiors of giant planets — where experts believe it gets squeezed until it becomes a liquid metal, capable of conducting electricity. Their work is published in Science. Hydrogen is ... Read More »

Autism linked to egg cells’ difficulty creating large proteins

New work from Carnegie’s Ethan Greenblatt and Allan Spradling reveals that the genetic factors underlying fragile X syndrome, and potentially other autism-related disorders, stem from defects in the cell’s ability to create unusually large protein structures. Their findings are published in Science. Their work focuses on a gene called Fmr1. ... Read More »

Previously grainy wheat genome comes into focus

The complete sequence of the huge wheat genome is published this week, and the enormous dataset will accelerate innovation in breeding resilient and disease resistant crops to feed a growing global population. Wheat is the most widely-cultivated crop on Earth. It provides more protein than meat in the human diet, ... Read More »

Sprawling galaxy cluster found hiding in plain sight

MIT scientists have uncovered a sprawling new galaxy cluster hiding in plain sight. The cluster, which sits a mere 2.4 billion light years from Earth, is made up of hundreds of individual galaxies and surrounds an extremely active supermassive black hole, or quasar. The central quasar goes by the name ... Read More »

Most wear-resistant metal alloy in the world

If you’re ever unlucky enough to have a car with metal tires, you might consider a set made from a new alloy engineered at Sandia National Laboratories. You could skid — not drive, skid — around Earth’s equator 500 times before wearing out the tread. Sandia’s materials science team has ... Read More »

Structurally ‘inside-out’ planetary nebula discovered

The Instituto de Astrofísica de Andalucía (IAA-CSIC) in Spain, the Laboratory for Space Research (LSR) of the University of Hong Kong (HKU), and an International team comprising scientists from Argentina, Mexico and Germany have discovered the unusual evolution of the central star of a planetary nebula in our Milky Way. ...

Smallest transistor switches current with a single atom in solid electrolyte

At Karlsruhe Institute of Technology (KIT), physicist Professor Thomas Schimmel and his team have developed a single-atom transistor, the world’s smallest. This quantum electronics component switches electrical current by controlled repositioning of a single atom, now also in the solid state in a gel electrolyte. The single-atom transistor works at ...

Printable tags turn everyday objects into smart, connected devices

Engineers have developed printable metal tags that could be attached to everyday objects and turn them into “smart” Internet of Things devices. The metal tags are made from patterns of copper foil printed onto thin, flexible, paper-like substrates and are made to reflect WiFi signals. The tags work essentially like ... Read More »

This matrix delivers healing stem cells to injured elderly muscles

A car accident leaves an aging patient with severe muscle injuries that won’t heal. Treatment with muscle stem cells from a donor might restore damaged tissue, but doctors are unable to deliver them effectively. A new method may help change this. Researchers at the Georgia Institute of Technology engineered a ... Read More »

Robots have power to significantly influence children’s opinions

Young children are significantly more likely than adults to have their opinions and decisions influenced by robots, according to new research. The study, conducted at the University of Plymouth, compared how adults and children respond to an identical task when in the presence of both their peers and humanoid robots. ... Read More »

Dating the ancient Minoan eruption of Thera using tree rings

New analyses that use tree rings could settle the long-standing debate about when the volcano Thera erupted by resolving discrepancies between archeological and radiocarbon methods of dating the eruption, according to new University of Arizona-led research. “It’s about tying together a timeline of ancient Egypt, Greece, Turkey and the rest ...

Iron and titanium in the atmosphere of an exoplanet

Exoplanets, planets in other solar systems, can orbit very close to their host star. When, in addition to this, the host star is much hotter than our Sun, then the exoplanet becomes as hot as a star. The hottest “ultra-hot” planet was discovered last year by American astronomers. Now, an ... Read More »

Congenital blindness reversed in mice

Researchers funded by the National Eye Institute (NEI) have reversed congenital blindness in mice by changing supportive cells in the retina called Müller glia into rod photoreceptors. The findings advance efforts toward regenerative therapies for blinding diseases such as age-related macular degeneration and retinitis pigmentosa. A report of the findings ... Read More »
