|---|---|---|
| 3,952 | X-rays and gravitational waves will combine to illuminate massive black hole collisions | A new study has found that collisions of supermassive black holes may be simultaneously observable in both gravitational waves and X-rays at the beginning of the next decade. |
| 3,953 | Watching complex molecules at work | A new method of infrared spectroscopy developed at BESSY II makes single-measurement observation and analysis of very fast as well as irreversible reaction mechanisms in molecules feasible for the first time. Previously, thousands of such reactions have had to be run and measured for this purpose. The research team has now used the new device to investigate how rhodopsin molecules change after activation by light -- a process that is the basis of how we see. |
| 3,954 | Silica particles may lead to new treatments for obesity and diabetes | Engineered ingestible molecular traps created from mesoporous silica particles (MSPs) introduced to the gut can have an effect on food efficiency and metabolic risk factors. The results from studies on mice demonstrate the potential to reduce the energy uptake into the body and could lead to new treatments for obesity and diabetes. |
| 3,955 | No need to dig too deep to find gold! | Why are some porphyry deposits rich in copper while others contain gold? A researcher investigated how the metals are accumulated over the time duration of a mineralizing event and discover that the depth of the deposits influences the quantity of metals produced and that over 95% of the gold is lost to the atmosphere. The deeper a deposit is, the more copper there will be, while gold-rich deposits are closer to the surface. |
| 3,956 | Galactic gamma-ray sources reveal birthplaces of high-energy particles | Nine sources of extremely high-energy gamma rays comprise a new catalog compiled by researchers with the High-Altitude Water Cherenkov (HAWC) Gamma-Ray Observatory. All produce gamma rays with energies over 56 trillion electron volts (TeV) and three emit gamma rays extending to 100 TeV and beyond, making these the highest-energy sources ever observed in our galaxy. The catalog helps to explain where the particles originate and how they are accelerated to such extremes. |
| 3,957 | Not so fast: Some batteries can be pushed too far | Fast charge and discharge of some lithium-ion batteries with intentional defects degrades their performance and endurance, according to engineers. |
| 3,958 | Colloidal quantum dot laser diodes are just around the corner | Scientists have incorporated meticulously engineered colloidal quantum dots into a new type of light emitting diodes (LEDs) containing an integrated optical resonator, which allows them to function as lasers. These novel, dual-function devices clear the path towards versatile, manufacturing-friendly laser diodes. The technology can potentially revolutionize numerous fields from photonics and optoelectronics to chemical sensing and medical diagnostics. |
| 3,985 | Street network patterns reveal worrying worldwide trend towards urban sprawl | New research has found that the local streets of the world's cities are becoming less connected, a global trend that is driving urban sprawl and discouraging the use of public transportation. |
| 3,986 | More federal funding needed to increase Americans' active transportation habits | The federal government has allocated only about 2 percent of its transportation funds to encourage walking and cycling, not nearly enough to make a significant difference, according to new research. |
| 4,011 | The wisdom of crowds: What smart cities can learn from a dead ox and live fish | In 1906, Francis Galton was at a country fair where attendees had the opportunity to guess the weight of a dead ox. Galton took the guesses of 787 fair-goers and found that the average guess was only one pound off of the correct weight -- even when individual guesses were off base. |
