For pedestrians, windy conditions can be uncomfortable or even downright dangerous. And while you might expect the buildings of an urban environment to protect people from the wind, that’s not always the case. The image above shows a simulation of ground-level wind conditions in Venice on a breezy day. While many areas, shown in blue and green, have lower wind speeds, there are a few areas, shown in red, where wind speeds are well above the day’s average. This enhancement often occurs in areas where buildings constrict airflow and funnel it together. The buildings create a form of the Venturi effect, where narrowing passages cause local pressure to drop, driving an increase in wind speed. Architects and urban designers are increasingly turning to numerical simulations and CFD to study these effects in urban environments and to search for ways to mitigate problems and keep pedestrians safe.

Hey guys, we made a flyer that you can print out and post in your places of choice! http://ift.tt/2jNXMm3
This artist’s impression shows the disc of gas and cosmic dust around the young star HD 142527. Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope have seen vast streams of gas flowing across the gap in the disc. These are the first direct observations of these streams, which are expected to be created by giant planets guzzling gas as they grow, and which are a key stage in the birth of giant planets.

Nerds at C2E2! We aren't drunk (yet) today but you certainly...Candice is so tired and can't think of what to say. So Rebecca here to finish. Check us out at Adler After Dark on May 18. Come meet us and dip some drunk ass science!!!!! #c2e2 #cosplay http://ift.tt/2pNLUXF
Nasa is to host a major press conference on a “discovery beyond our solar system”.
The event will see the revelation of major information about exoplanets, or planets that orbit stars other than our sun, according to a release. It made no further mention of the details of what would be revealed.
Exoplanets are the major hope for life elsewhere in the universe, since many have been found that resemble our own Earth and could have the building blocks of life. More of them are being discovered all the time.
The event will take place on 22 February at 1pm New York time, it said. It will be streamed live on Nasa’s television station and on its website.
Attending the press conference will be astronomers and planetary scientists from across the world.
Nasa said that the public will be able to ask questions using the hashtag #AskNasa during the conference. The agency will also hold a Reddit AMA, or ask me anything, session straight after the briefing.
Rebecca is loving this Snapchat filter from IWD 2017!!
