Black swifts descended rapidly during lunar eclipse

By Johan [dot] Joelsson [at] science [dot] lu [dot] se (Johan Joelsson) - published 17 March 2022 Black swift (Photo: Zak Pohlen) An international research team led by Lund University in Sweden has managed to study the flight behaviour of the mysterious black swift. They found, among other things, that the black swift rises to extreme heights during a full moon, seemingly catching insects in the m

What happens when plants have stress reactions to touch?

By johan [dot] joelsson [at] science [dot] lu [dot] se (Johan Joelsson) - published 24 May 2022 Olivier Van Aken and Essam Darwish. Photo: Johan Joelsson. A 30-year-old genetic mystery has been solved. It has previously been established that touch can trigger stress reactions in plants. However, the molecular models for explaining this process have been quite spartan so far. Now researchers at Lun

Ostriches can adapt to heat or cold – but not both

By johan [dot] joelsson [at] science [dot] lu [dot] se (Johan Joelsson) - published 31 May 2022 Photo: Charlie Cornwallis The ostrich is genetically wired to adapt to rising or falling temperatures. However, when the temperature fluctuates more often, as it does with climate change, the flightless bird with a 40-gram brain finds it much more difficult. A research team at Lund University has shown

Study reveals flaws in popular genetic method

Published 30 August 2022 Photo: Unsplash The most common analytical method within population genetics is deeply flawed, according to a new study from Lund University in Sweden. This may have led to incorrect results and misconceptions about ethnicity and genetic relationships. The method has been used in hundreds of thousands of studies, affecting results within medical genetics and even commercia
