New water treatment approach helps to avoid harmful chemicals

The water coming out of your faucet is safe to drink, but that doesn't mean it's completely clean. Chlorine has long been the standard for water treatment, but it often contains trace levels of disinfection byproducts and unknown contaminants. Georgia Institute of Technology researchers developed the minus approach to handle these harmful byproducts.

Nasa says distant exoplanet could have rare water ocean and possible hint of life

Space agency said potential finding of dimethyl sulfide on K2-18 b, produced only by life on Earth, is yet to be confirmedScientists at Nasa have announced the existence of a possible rare water ocean on a giant exoplanet scores of light years away and also a chemical hint of a sign of potential life.The “intriguing” discovery was made by the space agency’s James Webb telescope, peering 120...

Red fire ants, a dreaded pest, have invaded Europe

Last week, international experts warned that invasive species are costing the world economy almost half-a-trillion dollars annually . Today, researchers confirmed that one of the most fearsome invaders—the red fire ant ( Solenopsis invicta ), a pest native to South America that packs a painful sting and infests houses and crops—has taken hold in Italy. It...

You say tomato, these scientists say evolutionary mystery

Biologists have found evidence for evolutionary 'syndromes'-- sets of traits that occur together -- that help to explain how tomatoes first evolved their distinctive blend of color, sweetness, acidity and aroma. The research not only shines a light on how fruits evolve in the wild, but will also be valuable to crop-improvement efforts aimed at breeding more nutritious and appealing varieties of...

Urban parks built on former waste incineration sites could be lead hotspots

A new study finds that surface soil in parks and playgrounds built on former waste incineration and ash disposal sites may contain levels of lead exceeding EPA safety standards for areas where children play. The contamination, which can persist long after an incinerator is closed, stems from burning paint, pipes and other products that contained lead. Sites in hundreds of U.S. and Canadian cities...

Not too big: Machine learning tames huge data sets

A machine-learning algorithm demonstrated the capability to process data that exceeds a computer's available memory by identifying a massive data set's key features and dividing them into manageable batches that don't choke computer hardware. The algorithm set a world record for factorizing huge data sets during a test run on the world's fifth-fastest supercomputer. Equally efficient on laptops...
