Rising atmospheric CO2 levels can generally be tackled in three ways: developing alternative energy sources with lower emissions; carbon capture and storage (CCS); and capturing carbon and repurposing it. Researchers at Princeton University are claiming to have developed a technique that ticks two of these three boxes by using solar power to convert CO2 into formic acid.  Read More

The spherical middle chamber of DarkSide-50 is filled with 7,000 gal of scintillator fluid

Like the Higgs Boson, dark matter is one of those things in the Universe that evidence points to, but is very difficult to pin down. A team of researchers is looking to verify the existence of this most elusive of ingredients that is thought to make up 23 percent of the Universe using powerful detectors buried deep in an Italian mountain.  Read More

The HSC captured a high-resolution image of the entire Andromeda galaxy in one go (Image: ...

When taking snapshots, a good telephoto lens can be handy, but when your subject is 2.5 million light years away, it’s invaluable. To show off the capabilities of the new Hyper-Suprime Cam (HSC) located on Mauna Kea, Hawaii, an international team of astrophysicists has released high resolution images of the Andromeda galaxy that not only show off incredible detail, but may help shed light on the evolution of the Universe and the distribution of dark matter.  Read More

A Princeton University team has successfully merged electronics and biology to create a functional ear that can “hear” radio frequencies. The tissue and antenna were merged via the use of an “off-the -shelf” 3D printer, and the results have the potential to not only restore but actually enhance human hearing in the future.  Read More

Hydrogen is often hailed as a promising environmentally-friendly fuel source, but it is also relatively expensive to produce. However, new research conducted at Princeton University and Rutgers University poses the opportunity to produce hydrogen from water at a lower cost and more efficiently than previously thought possible.  Read More

The nanoscale metal mesh that makes up the top layer of the sandwich-like PlaCSH material

One of the main reasons that solar cells aren’t more efficient at converting sunlight into electricity is because much of that sunlight is reflected off the cell, or can’t be fully absorbed by it. A new sandwich-like material created by researchers at Princeton University, however, is claimed to dramatically address that problem – by minimizing reflection and increasing absorption, it reportedly boosts the efficiency of organic solar cells by 175 percent.  Read More

Fusion power would allow electricty to be generated using the same processes taking place ...

While solar power harnesses energy produced by the Sun, fusion power seeks to harness the very process used by the Sun to generate a practically limitless supply of clean electricity. Despite decades of research and numerous breakthroughs, “net-gain” nuclear fusion is yet to appear. One of the hurdles is the so-called density, or Greenwald, limit that sees the plasmas within experimental fusion reactors (called tokamaks) spiraling apart and disrupting the fusion process. Now scientists have come up with a new theory as to why this occurs that, if proven, could provide a way to clear the density limit hurdle.  Read More

A graphene sensor effectively tattooed onto a tooth can be used to detect bacteria and so ...

A graphene sensor effectively tattooed onto a tooth can be used to detect bacteria and so wirelessly monitor oral health, research has shown. Graphene printed onto water-soluble silk can be "bio-transferred" onto organic materials such as tooth enamel. By incorporating antimicrobial peptides and a resonant coil, individual bacteria cells can be detected without need of an onboard power supply or wired connections.  Read More

SignalGuru uses visual data from a network of smartphone cameras to tell drivers the optim...

The continuing increase in gasoline prices around the world over the past decade has also seen an increase in the practice of hypermiling – the act of driving using techniques that maximize fuel economy. One of the most effective hypermiling techniques is maintaining a steady speed while driving instead of constantly stopping and starting. Unfortunately, traffic lights all too often conspire to foil attempts at keeping the vehicle rolling. Researchers at MIT and Princeton have now devised a system that gathers visual data from the cameras of a network of dashboard-mounted smartphones and tells drivers the optimal speed to drive at to avoid waiting at the next set of lights.  Read More

Researchers at Princeton University developed a technique for generating a laser beam out ...

Princeton University engineers have developed a new laser sensing technology that is expected to enable the remote distant detection of explosives, airborne pollutants and greenhouse gasses. The technique differs from previous remote laser-sensing methods in that the returning beam is not just a reflection or scattering of the outgoing beam but an entirely new laser beam generated by oxygen atoms whose electrons have been "excited" to high energy levels. This "air laser" is a much more powerful tool than previously existed for remote measurements of trace amounts of chemicals in the air.  Read More
