A beetle fossil shows the insect may have helped spread cycad pollen 99 million years ago, and beetles may have been doing so since the early Mesozoic Era, according to findings published in Current Biology. The beetle was found encased in amber alongside a few grains of pollen, suggesting a relationship.
Innovative technology has revealed details on a map dating back to 1491 that may have informed explorer Christopher Columbus' view of the world. Researchers used multispectral imaging to create a copy of the map, allowing them to see parts that had been illegible because the original was so faded.
Some American crows migrate every winter and others remain where they are -- a behavior that is ingrained, rather than a conscious decision, a study published in The Auk: Ornithological Advances suggests. The study found the migrating crows always came back to the same breeding grounds, but they would vary their winter locales, likely due to climate and other environmental conditions.
Scotland's University of Glasgow has been awarded a $3.9 million grant from Cancer Research UK to study chronic myeloid leukemia treatments via lab experiments and a clinical trial. "We will take and analyze thousands of individual CML stem cells from patients enrolled in our clinical trial and study the biology of these cells both before and after treatment with new drugs," said study leader David Vetrie.
The National Hockey League Players' Association challenge has helped raise about $2.4 million for concussion research at Western University's Schulich School of Medicine and Dentistry in London, Ontario. Research will focus on studying concussion biomarkers and understanding symptoms.
Pinellas Technical High School opened its doors this week as the first full-time technical high school in Pinellas County, Fla. The school is offering six career programs in fields such as nursing, electricity, and digital and graphic arts, and there already is a waiting list for admissions.
Virtual reality tools are becoming a more affordable and faster way for employers to provide new hires with training that deepens expertise, write Tony DeMarinis, Lynne Calligaro, Cary Harr and Joe Mariani. VR allows trainees to work through scenarios in potentially dangerous or expensive settings such as refineries, wind turbines and chemical facilities.
Partial vision has been restored in blind mice after they were given two gene injections that transformed non-neuronal cells known as Muller glia into rod photoreceptors, according to a study published in Nature.
Pesticides created as a safer alternative to those harmful to bees may be just as dangerous for the insects and affect their reproduction, a study published in Nature suggests. "Our study highlights that stressors that do not directly kill bees can still have damaging effects further down the line," said Ellouise Leadbeater of Royal Holloway, University of London.
Iron and titanium have been detected in the atmosphere of a superhot exoplanet about 620 light-years from Earth. The extreme heat of KELT-9b helped researchers pinpoint the elements' presence, according to findings published in Nature.
