University of Massachusetts Amherst food science researchers have pinpointed a set of enzymes involved in tumor growth that could be targeted to prevent or treat colon cancer.

“We think this is a very interesting discovery,” says Guodong Zhang, assistant professor of food science, whose study was published in the journal Cancer Research. “Our research identifies a novel therapeutic target and could help to develop novel strategies to reduce the risks of colon cancer.”

Colon cancer is the third most common cancer and the second leading cause of cancer-related death in the United States, according to the Centers for Disease Control and Prevention, claiming some 50,000 lives each year. Those statistics emphasize the need to discover new cellular targets that are crucial in the development of colon cancer, Zhang says.

Thanks to blockchain, internet users have achieved some victories in the fight against China’s strict internet censorship.

A historic moment was made on April 23. Peking University’s former student, Yue Xin, had penned a letter detailing the university’s attempts to hide sexual misconduct. The case involved a student, Gao Yan, who committed suicide in 1998 after a professor sexually assaulted and then harassed her.

The letter was blocked by Chinese social networking websites, but an anonymous user posted it on the Ethereum blockchain.

In an interview newly published by Popular Mechanics, SpaceX CEO Elon Musk shared his thoughts on colonizing Mars — from how the first settlers will grow food to the friendly vibe he envisions at the first base on the Red Planet.

“For having an outdoorsy, fun atmosphere, you’d probably want to have some faceted glass dome, with a park, so you can walk around without a suit,” Musk told the magazine. “Eventually if you terraform the planet, then you can walk around without a suit. But for say, the next 100-plus years, you’ll have to have a giant pressurized glass dome.”

Drexler and the Oxford Future of Humanity Institute proposing that artificial intelligence is mainly emerging as cloud-based AI services and a 210-page paper analyzes how AI is developing today.

AI development is developing automation of many tasks and automation of AI research and development will enable acceleration of AI improvement.

Accelerated AI improvement would mean the emergence of asymptotically comprehensive, superintelligent-level AI services that—crucially—can include the service of developing new services, both narrow and broad, guided by concrete human goals and informed by strong models of human (dis)approval. The concept of comprehensive AI services (CAIS) provides a model of flexible, general intelligence in which agents are a class of service-providing products, rather than a natural or necessary engine of progress in themselves.

Modern theories of semantics posit that the meaning of words can be decomposed into a unique combination of semantic features (e.g., “dog” would include “barks”). Here, we demonstrate using functional MRI (fMRI) that the brain combines bits of information into meaningful object representations. Participants receive clues of individual objects in form of three isolated semantic features, given as verbal descriptions. We use machine-learning-based neural decoding to learn a mapping between individual semantic features and BOLD activation patterns. The recorded brain patterns are best decoded using a combination of not only the three semantic features that were in fact presented as clues, but a far richer set of semantic features typically linked to the target object. We conclude that our experimental protocol allowed us to demonstrate that fragmented information is combined into a complete semantic representation of an object and to identify brain regions associated with object meaning.

When they looked into how various physiological factors changed in the mice that had experienced chronic stress, the researchers closed in on a hormone called epinephrine.

New research in mice explains the mechanism through which chronic stress contributes to cancer cell growth and suggests a potential therapeutic strategy.

  • After years of development, the housing startup Arkup has debuted a floating home that can withstand rising sea levels and Category 4 hurricanes.
  • The home contains a hydraulic system that lifts it above water and anchors it during heavy winds.
  • Arkup envisions a future where entire communities in Miami and other major cities are designed to float.

When the housing startup Arkup revealed its plan to build a floating, hurricane-proof yacht in 2017, South Florida had just witnessed the devastating effects of Hurricane Irma, a Category 4 storm that destroyed hundreds of residences.

The company’s models were designed to weather a storm of that magnitude, but it would be another two years before they became a reality.
