Complete and functional 3D-printed human organs are a long way off, but significant advances are being made in the field that may produce more immediate benefits. Jean Thilmany examines six, including printable bioink, 3D-printed living skin and bioprinted heart tissue.
Coronavirus is captured in a nickel foam and instantly killed in a heated air filtration system developed by researchers at the University of Houston and private businesses. The system takes advantage of the virus expiring at temperatures higher than 158 degrees Fahrenheit.
A team at the University of California at Berkeley is transforming sleep apnea machines into respiratory devices for coronavirus patients. The machines are cleaned and retrofitted with parts approved by the Food and Drug Administration.
Mid-band spectrum in the 3450-3550 portion of the band is a "good candidate" for providing commercial 5G wireless service, the National Telecommunications & Information Administration suggests in a new report.

Physicists have observed branching flow for the first time in visible light created with a laser through a soap bubble. The waves "propagate in a peculiar way" when smooth variations exist, ultimately creating a pattern similar to tree branches, said Miguel Bandres of the University of Central Florida.
The Reinvest in Minnesota Program has turned 250,000 acres of the state's farmland back into wetlands, prairies and woods. It's not an easy process, however, as landowner Kevin Clinton illustrates with his bid to return more acreage to its native state by hacking away at non-native buckthorn.
The Eel River Recovery Project has issued a public draft for its erosion control and restoration plan for California's Tenmile Creek watershed. The plan is the result of a two-year project aimed in part at proposing community water conservation initiatives to nurture native fish and secure water for domestic and agricultural uses.
A 3.1-mile wall composed of five layers of geo-material is proposed to protect India's Uppada coast after erosion caused by waves generated during two cyclones. The solution proposed by the Department of Transport, Roads and Building calls for a wall 18 feet above the sea bed with layers of geo-fabric, tubing, sand, stone belt and concrete.
Manufacturing surged in June as monitoring surveys picked up renewed activity not only in the US, but in China and Europe as well.
