A widespread failure to validate research antibodies before use is estimated to lead to the avoidable waste of millions of animal and human tissue samples worldwide, and an international expert panel has reached consensus on how to address the problem, according to two studies published October 6^th in the open access journal PLOS Biology by Harvinder Virk of the University of Leicester, UK, and colleagues.

Florida State University faculty are helping build stronger structures by examining how wave-shaped patterns on exterior walls and roofs reduce wind loads on low-rise buildings by up to 60%.

The only known supernova remnant of its kind in the Milky Way has an unexpectedly intricate structure: chains of gas knots resembling pearls on a string, each wide enough to fit the solar system multiple times. Using the Gemini North telescope, an international team co-led by Ilaria Caiazzo, assistant professor at the Institute of Science and Technology Austria (ISTA), captured the most detailed view yet of Pa 30, revealing striking new features of the remnant associated with a historical supernova witnessed nearly 850 years ago. The findings were published in The Astrophysical Journal.

Researchers at Kyushu University have developed a VR system that requires no head-worn device. Using aerial imaging optics, the system presents stereoscopic imagery to both eyes, letting users enter a VR environment simply by sitting down. By removing the weight of a headset and moving image processing outside the wearable device, the system could enable more comfortable, longer VR use. The researchers expect it to find applications in remote operation, healthcare, education, and entertainment.
