The toughest plants survived ‘the Great Dying’

Unusually detailed plant fossils unearthed in Jordan suggest that several major lineages of fern and conifer species survived the world’s greatest extinction event. Some studies suggest that up to 90% of all land animals went extinct during a cataclysm of climate change and environmental upheaval that took place around 250 million years ago. The plants might have fared better because they were already adapted to harsh environments and seasonal droughts.

Scientists under siege in Nicaragua

Ongoing protests and a security crackdown in Nicaragua have engulfed the country’s scientists, causing some to flee their homes in fear for their lives. Universities have fired faculty members who have criticized the administration, and scientific conferences have been moved or postponed. The government has shut down and seized the property of nine non-governmental organizations, including the Fundación del Río, which focuses on environmental protections for the southeastern region of Nicaragua.

Animal-cruelty case against neuroscientist dismissed

A court in Germany has dismissed a high-profile case of alleged animal cruelty brought against neuroscientist Nikos Logothetis and two colleagues. The case has roots in 2014, when an undercover animal-welfare activist secretly filmed in Logothetis’s lab at the Max Planck Institute for Biological Cybernetics (MPI-Biocyb). The case provoked outcry among scientists, after the Max Planck Society revoked some of Logothetis’s duties and rights.

The call centre for DNA discoveries

At consumer-DNA companies, staffing the phones means answering calls from people who have just found out their child is not related to them by blood, or they have siblings they didn’t know about. “Somebody has known something their whole life and then this company is telling them something different,” says Kent Hillyer, head of customer care for the genetic-testing firm 23andMe. “And then it’s like, ‘Hey, I’m heading to a Thanksgiving dinner. Can you help me out with this before I go have this conversation with my mother?’”

INFOGRAPHIC OF THE WEEK

A healthy liver (1) can be damaged by scarring (2), which can further progress to cirrhosis (3) and raise the risk of liver cancer (4). Now, as understanding of scar formation grows, scientists are inching closer to treatments that harness the organ’s ability to heal itself.
