Gaps in malaria migration record filled thanks to old blood drops
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.

Astronomers see spiral arms surrounding new star for first time
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.

Ancient fossil raises new questions about how reptiles evolved
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.

Head muscle, bone cells damaged by Zika infection, study suggests
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.

Pediatric melanoma may appear as benign skin lesions
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.
