The risk of a bird flu pandemic is rising How worried should we be about bird flu? The past few months have seen some potentially worrisome developments in the US, including the continued spread of the virus among dairy cattle, the detection of the virus in a pig as well as cows milk, andmost concerning of allthe growing number of human infections. We dont yet have any evidence that the virus is spreading between people, but the risk of a potential pandemic has increased since MIT Technology Review last covered this topic a couple of months ago. The good news is we are in a much better position to tackle any potential future flu outbreaks than we were to face covid-19 back in 2020, given that we already have vaccines.

The moon is just the beginning for this waterless concrete If NASA establishes a permanent presence on the moon, its astronauts homes could be made of a new 3D-printable, waterless concrete. Someday, so might yours. By accelerating the curing process for more rapid construction, this sulfur-based compound could become just as applicable on our home terrain as it is on lunar soil. Traditional concrete requires large amounts of water, a commodity that will be in short supply on the moon, and sending just 1 kilogram of it to the moon costs roughly $1.2 million.Instead, NASA hopes to create new materials from lunar soil and eventually adapt the same techniques for building on Mars. But creating the perfect waterless lunarcrete is easier said than done. Read the full story.
