Heart of an Exploded Star Observed in 3-D

Supernovas — the violent endings of the brief yet brilliant lives of massive stars — are among the most cataclysmic events in the cosmos. Though supernovas mark the death of stars, they also trigger the birth of new elements and the formation of new molecules.

NASA Gives Eastern Pacific Ocean's Hurricane Eugene 'Eye Exam'

NASA satellites gave the Eastern Pacific Ocean's Hurricane Eugene an "eye exam" as it studied the storm in infrared and visible light. NASA satellite imagery taken at different times showed Eugene's eye open and closed.

Kansas State University researchers help with landmark study of wild wheat ancestor

Kansas State University scientists are part of a breakthrough study in which an international team of researchers has successfully deciphered all 10 billion letters in the genetic code of a wild ancestor of wheat.

Their work is published in the July 7 issue of Science Magazine.

“The relative of wheat is called wild emmer, which is one of the founding crops of human society,” said Eduard Akhunov, professor of plant pathology and wheat genomics at Kansas State University. “Wild emmer was one of the first crops that was domesticated 10,000 years ago, which was a critical step in moving from hunting and gathering to an agricultural society.”

UMass Amherst Food Scientists Find Cranberries May Aid the Gut Microbiome

Many scientists are paying new attention to prebiotics, that is, molecules we eat but cannot digest, because some may promote the growth and health of beneficial microorganisms in our intestines, says nutritional microbiologist David Sela at the University of Massachusetts Amherst. In a new study, he and colleagues report the first evidence that certain beneficial gut bacteria are able to grow when fed a carbohydrate found in cranberries and further, that they exhibit a special nontypical metabolism.

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.
