Exercise is one of the best ways to slow down aging and its free too!

(Boston) — Older adults who experience good cardiac fitness may be also keeping their brains in good shape as well.

In what is believed to be the first study of its kind, older adults who scored high on cardiorespiratory fitness (CRF) tests performed better on memory tasks than those who had low CRF. Further, the more fit older adults were, the more active their brain was during learning. These findings appear in the journal Cortex. Difficulty remembering new information represents one of the most common complaints in aging and decreased memory performance is one of the hallmark impairments in Alzheimer’s disease.

Healthy young (18−31 years) and older adults (55−74 years) with a wide range of fitness levels walked and jogged on a treadmill while researchers assessed their cardiorespiratory fitness by measuring the ratio of inhaled and exhaled oxygen and carbon dioxide. These participants also underwent MRI scans which collected images of their brain while they learned and remembered names that were associated with pictures of unfamiliar faces.

The TeraStructure algorithm can analyze genome sets much larger than current systems can efficiently handle, including those as big as 100,000 or 1 million genomes. Finding an efficient way to analyze genome databases would allow for personalized healthcare that takes into account any genetic mutations that could exist in a person’s DNA.

What’s the future of education? How will students learn differently? What will the schools of the future look like? We asked TED-Ed Innovative Educators to share their ideas. Their answers are provocative, contradictory — and make for great conversation starters. Welcome to the “Choose Your Own Adventure” future of learning.

There will be more creativity in education. “Because that’s what careers will require. Education will be not just taking in information and sharing it back, but also figuring out what to do with that information in the real world.” —Josefino Rivera, Jr., educator in Buenos Aires, Argentina.

The classroom will be one big makerspace. “Technology like Evernote, Google, and Siri will be standard and will change what teachers value and test for. Basically, if you can ask Siri to answer a question, then you will not be evaluated on that. Instead, learning will be project based. Students will be evaluated on critical-thinking and problem-solving skills. Literature and math will still be taught, but they will be taught differently. Math will be taught as a way of learning how to solve problems and puzzles. In literature, students will be asked what a story means to them. Instead of taking tests, students will show learning through creative projects. The role of teachers will be to guide students in the areas where they need guidance as innovators. How do you get kids to be innovative? You let them. You get out of their way.” —Nicholas Provenzano, educator in Michigan, United States.

Last year, doctors in the United States were unable to treat a patient infected with a bacterial strain that was resistant to 26 different antibiotics. After subjecting the bacteria to multiple tests, the doctors found it to be “resistant to all available antimicrobial drugs”, and the 70-year-old patient unfortunately died from the infection.

Detailed in a newly released Centers for Disease Control and Prevention report, the case highlights the significant threat that the emergence of highly resistant bacteria is becoming to global public health. The woman in the report was initially admitted to a hospital in Reno, Nevada, after she had returned from an extended trip to India with an infected swelling in her right hip.

After doctors conducted tests, they found she was infected with a form of carbapenem-resistant Enterobacteriaceae known as Klebsiella pneumoniae. Normally living in the gut without causing any issues, K. pneumoniae is opportunistic in its infection. It seems that in the case of the woman in this latest report, the infection entered the bone after a femur fracture in India, and then subsequently spread to her hip.
