2 . Scientists have found a way to decode (解码) a stream of words in the brain using MRI scans and artificial intelligence. The system reconstructs the main point of what a person hears or imagines, rather than trying to copy each word, a team reports. “It’s getting at the ideas behind the words, the meaning, says Alexander Huth, an author of the study.

Previous efforts to decode language have relied on sensors placed directly on the surface of the brain. The sensors detect signals in areas involved in expressing words. But the Texas team’s approach is an attempt to “decode more freeform thought,” says Marcel Just, a professor of psychology at Carnegie Mellon University.

The new study came about as part of an effort to understand how the brain processes language. Researchers had three people spend up to 16 hours each in a functional MRI scanner, which detects signs of activity across the brain. Participants wore headphones that streamed audio from the Internet. Those streams of words produced activity all over the brain, not just in areas associated with speech and language. After participants listened to hours of stories in the scanner, the MRI data was sent to a computer. It learned to match specific patterns of brain activity with certain streams of words. Then came a paraphrased version of what a participant heard.

The MRI approach is currently slower and less accurate than an experimental communication system being developed for paralyzed people, where people get a sheet of electrical sensors implanted directly on the surface of the brain. With an MRI-based system, no one has to get surgery.

But future versions of MRI scans could raise moral questions. “What if you can read out the word that somebody is just thinking in their head? That’s potentially a harmful thing.” Huth says. This technology can’t really read minds uncontrollably, though. It only works when a participant is actively cooperating with scientists. Still, systems that decode language could someday support people who are unable to speak because of a brain injury or disease. They are also assisting scientists in understanding how the brain processes words and thoughts.

3 . There are a lot of strategies for visiting a museum and avoiding “museum tiredness”. Consider what is mentioned below in planning.     1    

Regardless of a museum’s size, you’ll get tired quickly if you try to look closely at every object displayed. Likewise, most museums provide lots of information about the objects on view. So don’t try to read everything.     2     “Tombstone” labels are very brief and provide facts about the artist, their country etc. There may be a number, which the museum uses to register the object, usually according to when it became a part of the collection, and a credit line that indicates the donor. Object labels are placed next to many objects.     3     The approach used to write museum labels has been much debated among art historians and museum professionals.

    4     Ask for a map, or have museum staff suggest highlights in the collection or special exhibitions. Many museums have special tours, audioguides, or downloadable apps that point you to these objects.

Some people recommend setting a specific amount of time for your visit (1 or 2 hours).     5     In addition to benches in the galleries, most museums have a cafe, shop, sculpture courtyard or gardens where you can hang out and relax for a bit.

A．You’ll likely meet with two types of labels.

B．You are sure to make the most of your experience.

C．It’s always a good idea to stop by the information desk.

D．It would also be wise to plan frequent breaks in the galleries.

E．Note that these might not be artworks that you find appealing.

F．If you live near, consider frequent visits to the changed exhibitions.

G．These aim to give information not always obvious about the artwork.

5 . For high schoolers, a career goal can help them choose a major and college. They may find a career that fits for the first try. Therefore, do encourage the career exploration below. It describes a few new ones that will be available when your teen reaches adulthood.

Next-generation psychological help

Unfortunately, psychological health issues are unlikely to decrease soon. The existing research is far from a cure-all. Psychological help will likely be an ever more interesting and in-demand profession.

Intermediate health care provider

The U. S. is facing an overburdened health care system. So, an ever-higher percentage of health care will be provided by intermediate-care providers such as physician assistant, dental assistant, etc. The good news for career-seekers is that the training is much shorter.

Software developers and engineers

Experts in database architecture, artificial intelligence, and machine learning will stay in demand. New applications may include AI-assisted diagnosis (诊断) and treatment recommendations, individualized education, and advanced embryo (胚胎) selection to ensure absence of genetically influenced diseases and so on.

Precision medicine

In your teen’s lifetime, major diseases will likely be prevented and/or treated with molecules custom-matched (定制) to the very specific disease. Your math-centric teen who can picture getting a PhD could help make that happen.

Tips

It’s great when teens are able to explore careers on their own. You might want to sit alongside, but let your teen sit in the driver’s seat. Only help as much as needed.
