Tech startups gravitate toward cities with strong social networks, study finds
The presence of technology startups can drive economic growth for their home cities. So how can cities better appeal to entrepreneurs? A new study from the McCombs School of Business at The University of Texas at Austin shows the connections they can offer matter more than big money.
Women wearing hijabs in news stories may be judged negatively
Women wearing a veil or headscarf in the United States may face harsher social judgement, according to a study by Penn State researchers that found when given the same information in a news story, some people may consider a woman wearing a headscarf to be more likely to have committed a crime.
NASA finds second tropical system develops in Arabian Sea
Tropical Storm 07A has developed in the eastern Arabian Sea, one day after Tropical Storm 06A developed in the western part of the sea. Infrared imagery from an instrument aboard Terra revealed that very high, powerful storms with very cold cloud top temperatures were southwest of the center.

Coral gardeners bring back Jamaica's reefs, piece by piece
Everton Simpson squints at the Caribbean from his motorboat, scanning the dazzling bands of color for hints of what lies beneath. Emerald green indicates sandy bottoms. Sapphire blue lies above seagrass meadows. And deep indigo marks coral reefs. That's where he's headed.
For some corals, meals can come with a side of microplastics
Tiny microplastic particles are about as common in the ocean today as plastic is in our daily lives.
Siting cell towers needs careful planning

The health impacts of radio-frequency radiation (RFR) are still inconclusive, but the data to date warrants more caution in placing cell towers. An engineering team considers the current understanding of health impacts and possible solutions, which indicate a 500-meter (one third of a mile) buffer around schools and hospitals may help reduce risk for vulnerable populations.
Successful instrument guidance through deep and convulted blood vessel networks
A team led by Professor Sylvain Martel at the Polytechnique Montréal Nanorobotics Laboratory has developed a novel approach to tackling one of the biggest challenges of endovascular surgery: how to reach the most difficult-to-access physiological locations. Their solution is a robotic platform that uses the fringe field generated by the superconducting magnet of a clinical magnetic resonance...
NASA's exoplanet-hunting mission catches a natural comet outburst in unprecedented detail
Using data from NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers at the University of Maryland (UMD), in College Park, Maryland, have captured a clear start-to-finish image sequence of an explosive emission of dust, ice and gases during the close approach of comet 46P/Wirtanen in late 2018. This is the most complete and detailed observation to date of the formation and dissipation...
