Could concrete help solve the problem of air pollution?

Study indicates concrete construction waste can help rid the air of sulfur dioxide, a major pollutant.

A simple solution for terrible traffic

Cities plagued with terrible traffic problems may be overlooking a simple, low-cost solution: High-occupancy vehicle (HOV) policies that encourage carpooling can reduce traffic drastically, according to a new study co-authored by MIT economists.

The results show that in Jakarta, Indonesia, travel delays became 46 percent worse during the morning rush hour and 87 percent worse during the evening rush hour, after an HOV policy requiring three or more passengers in a car was discontinued on important city center roads.

Study finds hackers could use brainwaves to steal passwords

Researchers at the University of Alabama at Birmingham suggest that brainwave-sensing headsets, also known as EEG or electroencephalograph headsets, need better security after a study reveals hackers could guess a user’s passwords by monitoring their brainwaves.

EEG headsets are advertised as allowing users to use only their brains to control robotic toys and video games specifically developed to be played with an EEG headset. There are only a handful on the market, and they range in price from $150 to $800.

Wild Wheat Genome Sequencing Provides 'Time Tunnel' Capable of Boosting Future Food Production and Safety

A global team of researchers has published the first-ever Wild Emmer wheat genome sequence in Science magazine. Wild Emmer wheat is the original form of nearly all the domesticated wheat in the world, including durum (pasta) and bread wheat. Wild emmer is too low-yielding to be of use to farmers today, but it contains many attractive characteristics that are being used by plant breeders to improve wheat.

Meniscus-Assisted Technique Produces High Efficiency Perovskite PV Films

A new low-temperature solution printing technique allows fabrication of high-efficiency perovskite solar cells with large crystals intended to minimize current-robbing grain boundaries. The meniscus-assisted solution printing (MASP) technique boosts power conversion efficiencies to nearly 20 percent by controlling crystal size and orientation.

Camera-trap research paves the way for global monitoring networks

Biodiversity loss is one of the driving factors in ecosystem change, on par with climate change and human development. When one species, especially a large predator, disappears from an area, other populations will be affected, sometimes changing entire landscapes.

Advanced Modeling Technique Suggests Extreme Coastal Sea Levels More Likely

Improving projections for how much ocean levels may change in the future and what that means for coastal communities has vexed researchers studying sea level rise for years, but a new international study that incorporates extreme events may have just given researchers and coastal planners what they need.

The study, published today in Nature Communications  uses newly available data and advanced models to improve global predictions when it comes to extreme sea levels. The results suggest that extreme sea levels will likely occur more frequently than previously predicted, particularly in the west coast regions of the U.S. and in large parts of Europe and Australia.

NASA Sees Weakening of Tropical Depression 4

NASA satellite imagery revealed that Tropical Depression 4 appears to be losing its punch, and the National Hurricane Center expects the storm to weaken.

On July 7, 2017, at 11:30 a.m. EDT (1530 UTC), the Moderate Resolution Imaging Spectroradiometer, or MODIS, instrument aboard NASA's Terra satellite captured a visible image of Tropical Depression 4 as it continued moving through the north Central Atlantic Ocean. The image showed that the depression consisting of a possible circulation center embedded within a very small area of intermittent convection. The MODIS image does not show much organization.

Greenland's summer ocean bloom likely fueled by iron

Iron-rich meltwater from Greenland’s glaciers are helping fuel a summer bloom of phytoplankton.

Changes in brain regions may explain why some prefer order and certainty, UCLA behavioral neuroscientists report

Why do some people prefer stable, predictable lives while others prefer frequent changes? Why do some people make rational decisions and others, impulsive and reckless ones? UCLA behavioral neuroscientists have identified changes in two brain regions that may hold answers to these questions.
