A commentary in Nature proposes a complete overhaul of how we treat our wastewater. Among the benefits would be new energy-producing industry and reduce greenhouse gas emissions!... Read more »
Carbon fees are a tremendous policy tool to reduce greenhouse gas emissions. But what is their effect on other public health missions, like providing cleaner cookware to the poor in developing countries. We take a look at new research designing policy to meet both public health needs.... Read more »

Thanks to the Internet, amateur volunteers known as "citizen scientists" can readily donate their time and effort to science--in fields ranging from medicine to zoology to astrophysics. The astrophysics project Space Warps offers a compelling example of why citizen science has become such a popular tool and how valuable it can be.

In "Star Trek", a transporter can teleport a person from one location to a remote location without actually making the journey along the way. Such a transporter has fascinated many people. Quantum teleportation shares several features of the transporter and is one of the most important protocols in quantum information.... Read more »

New research demonstrates the use of a pulsed laser diode in photoacoustic tomography, a technique that uses light pulses to generate sound waves in a sample, which are then detected by an ultrasound detector and from which images can be produced computationally. Due to the higher pulse rate of this laser compared with those typically used, it was possible to image a dynamic system with frame rates up to 7000 frames per second. The authors also noted the benefits in terms of lower cost compared ........ Read more »

A new approach to atmospheric monitoring measures laser backscatter range as a function of angle using the Scheimpflug principle, instead of the more common time of flight method known as Lidar, which means it can monitor a large volume of space all at once. Given the name SLidar, it was demonstrated to work during daylight to measure cloud height and particle emissions using a diode laser. Compared with Lidar, the lasers and optics required for SLidar are cheaper and less complex, which could ........ Read more »

Quantum gravity appears today as the Holy Grail of physics. This is so far detached from any possible experimental result but with a lot of attentions from truly remarkable people anyway.

Two days ago, CERN presented their new results at 13 TeV to the World. Of course, collected data so far are not enough for conclusive results but the these are exciting anyway. The reason is that both the collaborations, CMS and ATLAS, see a bump at around 750 GeV in the decay. Summing up the results […]... Read more »

Why send a message back in time, but lock it so that no one can ever read the contents? Because it may be the key to solving currently intractable problems. It turns out that an unopened message can be exceedingly useful. This is true if the experimenter entangles the message with some other system in the laboratory before sending it.... Read more »

Millions of years ago our ancestors straightened up and started carrying tools around, instead of dropping them after use. And so technology became a part of daily routine.As time passed, more useful tools were made than it was feasible to carry or wear over the shoulder. One solution to this problem was monetary exchange, the other was a better technology. Wearables promised to add more convenience than carryables and, ever since humans started to wear clothes some 170,000 years ag........ Read more »
