A new chemical process could turn about 90% of the world’s grocery bags, shrink wrap, and other polypropylene waste into clean fuel.

Grocery bags and other trash could be melted down to yield useful products like oil and gas.

The problem: The world’s landfill sites and oceans are being flooded with plastic. A mere 9% of the 8.3 billion tons of plastic produced over the last 65 years has been recycled, according to the United Nations. Over eight million tons of plastic flow into our oceans every year, harming wildlife.

How it works: The technology works on polyolefin waste, the sort of plastic used for grocery bags, toys, and shrink wrap. This sort of plastic accounts for about 23% of plastic waste, according to researchers who describe the process in a paper published in Sustainable Chemistry and Engineering. The new technique uses a process called hydrothermal liquefaction, in which very high temperatures melt pellets of polyolefin and then dissolve them in water. The by-products of this process are oil, gas, or solvents.

The derivation of human embryonic stem cells (hESCs) and the stunning discovery that somatic cells can be reprogrammed into human induced pluripotent stem cells (hiPSCs) holds the promise to revolutionize biomedical research and regenerative medicine. In this Review, we focus on disorders of the central nervous system and explore how advances in human pluripotent stem cells (hPSCs) coincide with evolutions in genome engineering and genomic technologies to provide realistic opportunities to tackle some of the most devastating complex disorders.

Advances in stem cell biology are paving new paths toward their use in the clinic, especially toward understanding and treating neurological and neurodegenerative disease.

Harnessing an antitumor immune response has been a fundamental strategy in cancer immunotherapy. For over a century, efforts have primarily focused on amplifying immune activation mechanisms that are employed by humans to eliminate invaders such as viruses and bacteria. This “immune enhancement” strategy often results in rare objective responses and frequent immune-related adverse events (irAEs). However, in the last decade, cancer immunotherapies targeting the B7-H1/PD-1 pathway (anti-PD therapy), have achieved higher objective response rates in patients with much fewer irAEs.

This Perspective discusses the concept of immune normalization and how its underlying principles may help to augment, as well as design, cancer immunotherapies.

Finland knows it doesn’t have the resources to compete with China or the United States for artificial intelligence supremacy, so it’s trying to outsmart them. “People are comparing this to electricity – it touches every single sector of human life,” says Nokia chairman Risto Siilasmaa. From its foundations as a pulp mill 153 years ago, Nokia is now one of the companies helping to drive a very quiet, very Finnish AI revolution.

The small Nordic country is betting on education to give it a decisive edge in the age of AI.

This is proof that even technology needs a heart.” #SpaceApps #SpaceAppsPH http://verafiles.org/articles/isdapp-filipino-it-experts-wins-nasa-space-challenge

An app developed by a group of Filipino information technology professionals to assist local fishermen in their daily work has been named one of six global winners in the NASA Space Challenge, an announcement made on Feb. 16 said.

The much-awaited announcement was delayed for weeks because of the U.S. federal government shutdown.

ISDApp, an app that would enable fishermen to receive scientific data without Internet connection, was declared winner in the “Galactic Impact” category besting co-finalists from, India, Italy, Romania, and Slovenia.

Believe it or not, mosquitoes don’t bite out of spite. Female mosquitoes of the species Aedes aegypti need the nutrients present in your plasma to ensure the proper development of their eggs. And though their thirst may seem unquenchable, the ladies actually take time to savor your blood once they’ve sipped their fill.
