Drops of blood taken from malaria patients in Spain during the 1940s are helping researchers learn more about the disease's migration, according to findings published in the Proceedings of the National Academy of Sciences. Scientists reconstructed the genomes of malaria parasites found in the blood to help fill in gaps in how the disease evolved and spread.
The Rosetta space probe was expected to crash into Comet 67P/Churyumov-Gerasimenko this morning, effectively bringing its 12-year mission to an end. The probe arrived at the comet in August 2014, 10 years after leaving Earth, and has gathered a wealth of data about and images of the comet.
Spiral arms like those of the Milky Way have been spotted for the first time around a brand-new star 450 light-years away. "These results are the first detection of spiral density waves in the reservoir of gas and dust that surrounds a newborn star," said Laura Perez, lead author of a study published online in Science.
Happy bumblebees are productive bumblebees, according to a study published in Science that charted how the insects' changing moods affected their decision-making behavior. The findings are the first clues that primitive emotional states exist in bees.
Researchers' ideas on how reptiles evolved are being challenged by the newfound fossils of a creature that lived about 200 million years ago, according to findings published in Current Biology. The most unusual feature of Drepanosaurus, a reptile the size of a cat, was its huge, muscular arms and forearms, which did not have parallel bones, researchers say.
Cells that help form bone, cartilage and muscle in the head can be damaged by the Zika virus, according to a study published in Cell Host & Microbe. The virus infected cranial neural crest cells in lab-grown minibrains, and the finding could explain the unusual head shapes of Zika-infected babies born with microcephaly.
Researchers found that benign-appearing pediatric melanomas were more likely to be deeper and have a higher T stage, compared with melanomas with a clinically malignant appearance. The findings in the Journal of the American Academy of Dermatology, based on a review of 2000 to 2015 data involving youths with primary cutaneous melanoma ages 21 and younger, should prompt pediatricians to closely monitor benign-looking skin lesions with bleeding, evolution or ulceration history, researchers said.
How is software really used in schools? Online resources, from mobile apps to computer-based tools, abound for educators - but how are they really being used in schools, and how often? Read this SmartFocus on how schools can better analyze software data for more informed purchasing and greater student outcomes.
The Eunice Kennedy Shriver National Institute of Child Health and Human Development has awarded a $5.4 million grant to the Kansas Intellectual and Developmental Disabilities Research Center. The funds will support the center and its study of ways to improve spoken word production in children with autism spectrum disorder who are minimally verbal.
Scotland's University of Glasgow will share in a nearly $23 million grant from the UK's Engineering and Physical Sciences Research Council to study technologies to treat health problems experienced by the UK's older residents. The university, one of four sharing the award, will receive $5.8 million.
