An array of dinosaur tracks has been found along the Australian coast, according to a study published in the Journal of Vertebrate Paleontology. Researchers found 21 different kinds of tracks, including what is believed to be the largest dinosaur footprint to date, dating back between 90 million and 115 million years.
German researchers have found a way to reprogram the S. cerevisiae enzyme in baker's yeast -- usually used to catalyze long-chain fatty acid formation -- to produce short-chain fatty acids. The researchers say the method "can be plugged into essentially all currently available fatty-acid overproducing microorganisms" and has applications for cosmetics, soaps and pharmaceutical ingredients.
Innovate UK has awarded a $1.25 million grant to Scotland's Dundee University to study antimicrobial resistance and develop new antibacterial treatments. The funds will "significantly boost our work on bacterial diseases, where drug-resistant infections are threatening all countries and adversely impacting the clinical management of patients," said the university's Mike Ferguson.
US students have partnered with peers from Ghana to collaborate and solve a real-world problem as part of a science competition run by a global nonprofit. Students from McKinley Technology High School in Washington, D.C., have worked with their teammates from Winneba Senior High School in Ghana to address water issues that affect the world.
Some schools are using social media app Snapchat to encourage students to experiment with new forms of storytelling in journalism and marketing classes. Educators suggest creating a written policy that would include a social media user guide and tips for best practices.
Indiana high-school students will have the opportunity to explore IT careers by managing a technology help desk. The help desk staff will troubleshoot their fellow students' tech problems and maintain a team website, Twitter account and blog.
An asteroid impact on Mars about 3 billion years ago may have triggered huge tsunamis by a northern ocean into the planet's southern hemisphere, according to findings published in the Journal of Geophysical Research -- Planets. Massive thumbprint-shaped geological formations may have been caused by tsunamis triggered by the impact of the asteroid that made the Lomonosov crater, models suggest.
The Amazon River is at least 9 million years old, much older than previously thought, a new study suggests. "We were able to narrow down the age of onset of the Amazon River because we sampled the transition interval in a classical section of the Amazon submarine fan, where the sediments transported by this river are deposited and as a result accurately record its evolutionary history," said Farid Chemale, senior author of the study published online in Global and Planetary Change.
