Patient with Parkinson's gets experimental stem cell-based treatment
Researchers have placed 2.4 million dopamine precursor cells derived from induced pluripotent stem cells into the brain of a patient with Parkinson's disease, the first of seven people to undergo the experimental treatment. "The patient is doing well, and there have been no major adverse reactions so far," said researcher Jun Takahashi of Kyoto University in Japan, where the precursor cells were developed.

Vaccine to hinder malaria transmission under development
A liposome-based malaria vaccine is being developed that could prevent transmission of the disease by mosquitoes after they bite an infected person who has been inoculated, according to researchers Wei-Chiao Huang and Jonathan Lovell. "[W]e expect that when an uninfected mosquito bites a person infected with the malaria parasite, the blood it sucks up will carry the parasite and the human antibodies that will prevent the parasite from multiplying in the insect's gut," they write.

Footprints found in the Grand Canyon belonged to a tiny reptile that lived around 315 million years ago, according to findings presented at the Society of Vertebrate Paleontology's annual meeting. The creature moved with an unusual sideways gait, making the tracks look as if two reptiles had been walking next to each other.

Re-examination of satellite data shows hidden sub-Antarctic continents
A new examination of data collected by a defunct European Space Agency satellite has revealed lost continents underneath the ice in Antarctica. "In East Antarctica, we see an exciting mosaic of geological features that reveal fundamental similarities and differences between the crust beneath Antarctica and other continents it was joined to until 160 million years ago," said Fausto Ferraccioli, co-author of the study published in Scientific Reports.

Researchers creating lightweight bionic prosthesis using EMG
Turkish researchers are developing a lightweight, bionic prosthetic hand that uses electromyography to control its movements. The prosthesis, which extends to the elbow, weighs about the same as a human arm and is battery operated.

Ultrasound screening could identify CF patients at risk of cirrhosis
A nonuniform pattern on ultrasound images of cystic fibrosis patients' livers indicates higher scarring risk, according to a study presented at the North American Cystic Fibrosis Conference. The findings suggest ultrasound screening could predict cirrhosis in CF patients, and researchers are developing predictive models.

Antibiotic treatment for drug-resistant bacteria awarded $621,489 grant
The University of Lincoln in the UK has been awarded a $621,489 grant from the Department of Health and Social Care to further develop an antibiotic that could be used to treat drug-resistant bacteria. Researchers will use the funds to create synthetic forms of teixobactin, a natural antibiotic shown to be effective against such pathogens.
