NASA finds Akoni already post-tropical

Tropical Storm Akoni had a quick life as a tropical storm before transitioning into a post-tropical storm. NASA captured a visible image of as it was becoming a tropical storm and an infrared image after it transitioned.

NASA sees gabrielle go 'post-tropical...' for now

The Global Precipitation Measurement mission or GPM core satellite passed over the Eastern Atlantic Ocean and observed that Tropical Storm Gabrielle had become post-tropical. GPM also gathered data on rainfall rates occurring in transformed and elongated storm.

Beyond borders: Understanding migration requires understanding changing land systems

For tens of millions of people, migration is a tough reality. What causes people to migrate away from their home countries, and what happens when they do? Migrants and their labor are responsible for moving hundreds of billions of dollars around the world annually. At their destinations, they affect populations, cultures, and economies. But their movement also has a major impact on the places they...

Study of Dead Sea Scroll sheds light on a lost ancient parchment-making technology

First discovered in 1947 by Bedouin shepherds looking for a lost sheep, the ancient Hebrew texts known as the Dead Sea Scrolls are some of the most well-preserved ancient written materials ever found. Now, a study by researchers at MIT and elsewhere elucidates a unique ancient technology of parchment making and provides potentially new insights into methods to better preserve these precious...

Not all meat is created equal: How diet changes can sustain world's food production

If you wanted to really mess with the world's food production, a good place to start would be in Morocco. They don't grow much here, but it is home to mines containing most of the world's known reserves of phosphate rock, the main source of the nutrient phosphorus. Most of us across the globe, most days, will eat some food grown on fields fertilized by phosphate rock from these mines.

Combating prison recidivism with plants

A study out of Texas State University attempted to determine the number of available horticultural community service opportunities for individuals completing community service hours per their probation or parole requirements, and whether that brand of community service generates a calculable offset against the common nature of repeat offenses for an inmate population once released.

How to spin a disk around young protostars

How do stars and planets form? Scientists are now one step closer to pinning down the conditions for the formation of proto-stellar disks. Observations of three systems in the early stages of star formation in the Perseus cloud revealed that the profile of the angular momentum in these systems is between that expected for a solid body and pure turbulence, indicating that the influence of the core...

Metabolic engineering method succeeds in producing 1,2,4-butanetriol sustainably from biomass

A more environmentally-friendly and sustainable method of producing the useful chemical 1,2,4-butanetriol has been discovered. The Kobe University team were the first in the world to utilize a method involving the direct fermentation of xylose in rice straw using an engineered yeast strain to produce 1,2,4-butanetriol. In the course of conducting this research, the team successfully overcame two...

Nanoparticles in lithium-sulphur batteries detected with neutron experiment

Lithium-sulphur batteries are regarded as one of the most promising candidates for the next generation of energy storage devices. They have a theoretical gravimetric energy density that is five times higher than that of the best lithium-ion batteries currently available. And they even work at sub-zero temperatures of down to -50 °C. In addition, sulphur is inexpensive and environmentally...

Innovative method provides unique insights into the structure of cells and tissues

Cells are the basic building blocks of life—and, as such, they have been the object of intense study since the invention of the optical microscope in the 17th century. The development of mass spectrometry (MS) methods—those which define the chemical composition of cells—represent a further milestone for research in the field of cell biology. In the latest issue of the journal Nature Methods,...

Measuring changes in magnetic order to find ways to transcend conventional electronics

Researchers around the world are constantly looking for ways to enhance or transcend the capabilities of electronic devices, which seem to be reaching their theoretical limits. Undoubtedly, one of the most important advantages of electronic technology is its speed, which, albeit high, can still be surpassed by orders of magnitude through other approaches that are not yet commercially available.
