Single molecular layer and thin silicon beam enable nanolaser operation at room temperature
For the first time, researchers have built a nanolaser that uses only a single molecular layer, placed on a thin silicon beam, which operates at room temperature. The choice of two-dimensional materials and the silicon waveguide enabled the researchers to achieve room temperature operation. Excitons in molybdenum telluride emit in a wavelength that is transparent to silicon, making silicon possible as a waveguide or cavity material.
Saturn's moon Titan has a key ingredient that could be used to cook up life
Saturn's moon Titan harbors a key chemical ingredient that may allow organisms to exist on this distant, chilly world. That means the molecule - and possibly some form of cellular life - might be located on the moon's surface as well. If there was going to be life in Titan's oceans, then it's plausible vinyl cyanide could be a component of that.

Supernova-hunting team finds comet with aid of amateur astronomer
Carnegie's Benjamin Shappee is part of a team of scientists, including an Australian amateur astronomer, which discovered a new comet last week. Jose Prieto, a former Carnegie postdoc now a professor at Universidad Diego Portales in Chile, was the first ASAS-SN team member to notice the bright, moving object. Checking the catalog of known moving objects-asteroids and comets-did not give any known object at the position of the source.
Researchers pioneer greener way to create interwoven polymers with blue light
Polymers, which are materials made from chains of molecules, are found in everything from food to clothing to cars. These chemistries independently are used in a broad range of applications, from dental composites, automobile bumpers to drug delivery materials, Shete said. They use 470-nanometer blue light, which is similar to blue LED light used to detect certain body fluids in crime scene investigations. This is unique in the way the blue light induces sequential reactions, says Kloxin.
Sewage system failures plague Mexican tourist destinations
Sewage breakdowns in Mexico City's floating gardens of Xochimilco and in the country's Yucatan peninsula resort of Isla Holbox have officials warning of threats to residents and tourism. Local media reported fecal material is building up in the low swampy ground around Holbox's failing sewage treatment plant. A video shows men in tall rubber boots trudging through the lush jungle, water filled with feces up to their knees.
First Exomoon Found? Scientists May Have Discovered A Moon Orbiting An Exoplanet
Scientists may have discovered a moon orbiting an exoplanet for the first time ever. This possible moon was first detected using data from NASA's Kepler Spacecraft, which has been used to search for exoplanets. If this hunch proves to be real, it would be the first moon outside our solar system ever discovered. In this case, light reflecting off an exoplanet was dimmed when the exomoon passed in front of it. If the exomoon truly is there, scientists can learn a lot from it.
Art of Living event: New panel denies destruction of Yamuna floodplains
The report assumes significance as its findings are different to that of an earlier seven-member expert panel which had alleged that the Yamuna floodplains were completely destroyed due to the World Cultural Festival of AOL. This kind of grass and natural regeneration of seedlings is not possible on compacted soil. The area was also under water in small depressions in majority of the areas where function was held.

Poaching continues to pose severe threat to tigers in India
In India, reported tiger deaths related to poaching reached an all time high in 2016. All efforts to recover wild tigers are now imperiled by snaring on a massive scale. It`s impossible to know how many snares are being set up every day, and threatening wildlife in these critical habitats. TRAFFIC India introduced Deep Search Metal Detectors (DSMD) in 2008 which have been distributed to Tiger Reserves across the country.
Cricket's summer song making a comeback
The cheep, cheep, cheep of a cricket in the grass is the quintessential sound of summer. As I crunch over heathland in search of the elusive insect, the song fills the air, as if conjured up by a magician. The song of the field cricket was once a familiar soundtrack on the heaths and grasslands of south east England. Using a technique known as tickling, the young field crickets, known as nymphs, were tempted to leave their burrows and then captured.
Arizona aims to combat wrong-way driving with new technology
Arizona transportation officials are moving forward with a first-in-the-nation pilot program that will use thermal camera technology to curb the wrong-way driving problem plaguing the state. The detection system will illuminate a sign that notifies the wrong-way driver and immediately alert the state Department of Public Safety. Arizona Department of Transportation officials will update message boards along the interstate, cautioning other drivers of a wrong-way vehicle. Wrong-way drivers have killed at least eight deaths in Arizona this year.
Team manufactures magnets entirely from US-sourced rare earths
The Critical Materials Institute, a US Department of Energy Innovation Hub, has fabricated magnets made entirely of domestically sourced and refined rare-earth metals. In the global rare-earth metals market, the provenance is extraordinary- US-mined ores, domestically processed, and domestically manufactured into magnets. This was a stretch goal of the Critical Materials Institute, to demonstrate that rare-earth magnets could be produced from mine to manufacturer, here in the United States.
In solar eclipse's 'path of totality,' rooms go for $1,000 and vendors sell every trinket under the sun
The Great Solar Eclipse is coming, and there's money to be made. With more than 12 million people living in the so-called path of totality, and millions more traveling to see the historic Aug 21 solar eclipse, companies and enterprising individuals are sensing opportunity. Jonathan Frey, general manager of Frey wines, expects to sell out of the specialty wines before the eclipse. Most traditional lodging facilities have been booked for months if not years, leading people to jack up prices on Airbnb.
New NC island was expected to eventually disappear, but not like this
North Carolina's new island may not be an island much longer. Just a few weeks ago, visitors had to swim to the island in waters that got more than 6 feet deep at high tide. Meanwhile, Hallac is looking into who would have official ownership of Shelly Island once it's connected to the Cape Hatteras National Seashore. It was originally considered dangerous to visit the island, because the channel separating it from Hatteras Island was filled with swift waters, sharks and stingrays.
Scientists find moon of Saturn has chemical that could form 'membranes'
NASA scientists have definitively detected the chemical acrylonitrile in the atmosphere of Saturn's moon Titan, a place that has long intrigued scientists investigating the chemical precursors of life. Under the harsh conditions of Saturn's largest moon, this chemical is thought to be capable of forming stable, flexible structures similar to cell membranes. Now, NASA researchers have identified the chemical fingerprint of acrylonitrile in Titan data collected by the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile.
Computer models provide new understanding of sickle cell disease
Computer models developed by Brown University mathematicians show new details of what happens inside a red blood cell affected by sickle cell disease. Sickle cell disease affects hemoglobin, molecules within red blood cells responsible for transporting oxygen. The stiff, ill-shaped cells can become lodged in small capillaries throughout the body, leading to painful episodes known as sickle cell crisis. We are able to produce a polymerization profile for each of the cell types associated with the disease, Karniadakis said.
New light-activated catalyst grabs CO2 to make ingredients for fuel
Scientists have developed a light-activated material that can chemically convert carbon dioxide into carbon monoxide without generating unwanted byproducts. The achievement marks a significant step forward in developing technology that could help generate fuel and other energy-rich products using a solar-powered catalyst while mitigating levels of a potent greenhouse gas. In carbon dioxide reduction, you want to come away with one product, not a mix of different things.
