Humans may not have landed on Mars （火星） just yet, but that isn’t stopping a European company from devising a plan to send four people to the Red Planet within the next few years. This project, called Mars One, aims to send a small group of people to Mars in 2022 and eventually establish a permanent colony on the planet.

“Everything we need to go to Mars exists,” said Mars One co-founder Bas Lansdorp in March 2014. “We have the rockets to send people to Mars, the equipment to land on Mars, the robots to prepare the settlement for humans. For a one-way mission, all the technology exists.” Yet the four astronauts chosen for the trip will be stuck on Mars—forever. And despite Mars One’s thorough planning, there are a number of challenges that may prevent the mission from ever taking place. The biggest road block could be the mission's huge cost （$6 billion）. However, Lansdorp is confident that Mars One will be able to fund the project by selling the broadcast rights for the mission and subsequent experiences living on the planet.

Those broadcast rights will also play a part in helping to select the people who will be sent to Mars. Lansdorp said the company will hold a selection process similar to a reality show. Lansdorp is expecting at least 1 million applications from people around the world. In addition to the cost, several other potential problems could inhibit （阻止） the mission to Mars.

“It’s even more challenging to send people there with life support, with food, with air, with all the other things like books, entertainment, means of communication and of providing for their own resources for a long stay on Mars,” said Adam Baker, senior lecturer in space engineering at Kingston University in London. “The size of the rockets you’d need to do this would be absolutely colossal.”

1.According to Project Mars One, humans could send four people to Mars within the next ________years.

A．seven B．eight C．ten D．six

An electric signal can trick a monkey’s brain into believing the animal’s finger has been touched.

Touch something, and your brain knows. The hand sends signals to the brain to announce contact was made. But that feeling of touch may not require making actual contact, tests on monkeys now show. Zapping brain cells can fool the animal into thinking its finger has touched something.

A person who has lost a limb or become paralyzed may need an artificial limb to complete everyday tasks. But such patients may not truly feel any objects they hold. The new findings point toward one day creating a sense of touch in those who use such artificial limbs. Psychologist Sliman Bensmaia of University of Chicago worked on the new tests. His team’s findings appeared on October 14 in the Proceedings of the National Academy of Sciences of the United States of America.

The sense of touch is crucial to everyday tasks: People without it may have difficulty cracking an egg, lifting a cup or even turning a doorknob. That’s why restoring it is a major goal for designers of artificial limbs.

In their new study, Bensmaia and his co-workers worked with rhesus monkeys (恒河猴). The scientists implanted electrodes (电极)--- small devices that can detect and relay an electrical signal—into the animals’ brains. The scientists used the electrode data to identify which neurons had become active. Then the scientists used the implanted electrodes to zap those same neurons. And the monkeys reacted as though their fingers had been touched. In fact, they hadn’t.

The monkeys couldn’t use words to tell the scientists what they had felt. Instead, they communicated by looking in a particular direction—just as when they had really been touched.

The new findings show how touch-sensitive devices could be built. The new study also offers “ a nice clear pathway” for figuring out how to restore a sense of touch to an amputee(被截肢者) or someone with a injury of spinal cord.

The study shows how artificial limbs might be connected to the brain so that a person can “feel” with such a prosthesis (假肢). But such a supersensory device doesn’t exist yet and scientists have a lot of work to do before people will benefit from it. Researchers must first figure out whether the electrodes would work in people in the same way they do in monkeys.

“ I think the foundation is laid for human trials,” Bensmaia said.
