【推荐1】Federal laws have been in place to protect archaeological (考古学的) resources for more than a century.    1    However, decades later the law's language was deemed too vague to offer adequate protection from looters (劫掠者) and vandals ( 故意破坏公物者). In response, the Archaeological Resources Protection Act was enacted in 1979.    2    

Yet theft, vandalism, and looting continue to pose serious threats to our cultural resources, and land managing agencies, tribal communities, and others are faced with the challenge of protecting heritage sites. A 2010 National Park Service report revealed that more than 3,000 cases of vandalism and looting on federal lands were documented within a 3-year period, and many more are likely unreported. Destructive behaviors range from the harmful act of artifact collecting to the criminal activity of looting and grave robbing.    3    For example, some artifacts (古手工艺品) are removed from their contexts by collectors.

Ancestral sites and surface artifacts are abundant in the Southwest. These material remains maintain connections to ancient traditions and cultural identity.    4     Acts of theft and destruction cause real and lasting harm, depriving us of the opportunity to learn about and appreciate the history of our land. Looters disturb human remains and steal from graves for financial gain, thereby negatively impacting the spiritual health and wellbeing of Native American communities.     5    A shared goal among many archaeologists is to increase public awareness to help stop this destruction, but we are only subset of preservation- minded groups. The support of other parties like tribal communities, environmental advocates and historians is necessary to protect archaeological resources and sacred landscapes.

【推荐2】French children are saying "Hello" to the new academic year and "Bye" to their cell phones during school hours． That's because a new law has come into effect which bans phone use by students up to the age of 15． The legislation， which follows a campaign promise by French President Emmanuel Macron， also bans tablets and smart watches．

The ban is also in place at break times， with exceptions in cases of emergency and for disabled children， the French Education Ministry said in a statement． In emergencies， students can ask their teachers for permission to use their phones． Meanwhile， high schools can voluntarily carry out the measure．

Education Minister Jean-Michel Blanquer said the new rules aim to help children focus on lessons， better socialize and reduce social media use． The ban is also designed to fight online bullying and prevent thefts and violence in school． Blanquer has claimed the legislation would improve discipline among France's 12 million school students， nearly 90% of whom have mobile phones． "Being open to technologies of the future doesn't mean we have to accept all their uses，" Blanquer said in June as the bill was going through in Parliament．

As for enforcement， it's up to individual school administrations to decide how to put through the ban． School principals can decide to store students' phones in lockers or allow them to keep them， switched off， in their backpacks． The law allows teachers to take away the phones until the end of the day in case of someone disobeying the bans．

Jacqueline Kay-Cessou， whose 14-year-old son， David， is entering eighth grade at the Camille See International School， told the reporter she was happy to hear of the ban． "It's fantastic news． It's something I've wanted for years，" Kay-Ccssou said． "I think phones are socially harmful． Kids can't think and sit still anymore and it's highly addictive．"

【推荐3】The Pacific nation of Palau will soon ban many types of sunscreen in an effort to protect its coral reefs.

President Tommy Remengesau Jr, signed legislation (法令) recently that bans “reef toxic” (对珊瑚有毒) sunscreen beginning in 2020. The law defines reef toxic sunscreen as containing any one of 10 chemicals, including oxybenzone. Other chemicals may also be banned.

Officials will take banned sunscreens from visitors who carry them into the country, Businesses that sell the banned products will be fined up to $1,000.

In a statement, Remengesau said that the punishments find the right balance between “educating tourists and scaring them away.”

The law also requires tour operators to start providing customers with reusable cups, drinking straws and food containers.

The president said the legislation was introduced based on information from a 2017 report. The report found that sunscreen products were widespread in Palau’s famous Jelly fish Lake. The lake was closed for more than a year because of a decrease in jellyfish numbers. It was recently reopened.

The president also noted that plastic waste, chemical pollution, and climate change all threaten the country’s environmental health.

Scientists have found that some chemicals in sunscreen can be toxic to coral reefs. The reels are an important part of the ocean environment and popular with tourists, But some critics say there are not enough independent scientific studies on the issue. Others worry that people will suffer from too much sun contact if they stop using the products.

Some manufacturers have already started selling “reef-friendly” sunscreen.

Palau is located east of the Philippines and north of Indonesia. The nation is home to 21,000 people. Its economy depends on tourism and fishing.

【推荐1】As we all know, science is blooming more strongly than ever. Recently, NASA astronaut Scott Kelly showed a photo of the orange zinnia (百日菊)on Twitter. It is the first flower to ever bloom in space and has attracted much attention all over the world. This may be the most exciting news in the field of science. The zinnia in the picture is so beautiful and looks similar to that on earth. Kelly cared for it for more than a month.

The Veggie plant growth facility chose the zinnia flower species because it has a longer growth cycle. As a result, it can help scientists understand how plants flower and develop in microgravity(微重力).

“While the plants haven’t grown perfectly, ” said Gioia Massa, NASA science team leader for Veggie, “I think we have gained a lot from this, and we are learning both more about plants and fluids and also how better to operate between ground and the station. ”

This was not the first time that scientists had attempted to grow zinnia in space. Other astronauts aboard the International Space Station ( ISS ) began growing the colorful flowers last year. However, due to high humidity (湿度)and low air movement in space, the zinnia leaked (渗透)water out of the tips of the leaves. What was worse, the spread of harmful bacteria was destroying its growth badly. Kelly then took over the operation and began taking care of the zinnia as he would in his own garden.

The ISS also successfully grew red romaine lettuce in July 2015. Kelly even took a bite of the harvested plants and posted the photo on his Twitter. NASA’s new experiment using the Veggie plant growth system will be started later. Astronauts will attempt to grow Chinese cabbages. The space agency will then attempt to grow dwarf tomatoes in 2018.

【推荐3】Step into Moving to Mars, an exhibition of the Mars mission and colony design at London’s Design Museum, and immediately you have good reasons for not moving there.

Frightening glowing wall-texts announce that Mars wasn’t made for you, that there is no life and little precious water, that, dressed in a spacesuit, you will never touch, taste or smell the planet you now call “home”. As Lisa Grossman wrote for New Scientist a couple of years ago, “What’s different about Mars is that there is nothing to do there except try not to die.”

It is an odd beginning for such a celebratory exhibition, but it provides a valuable, dark background against which the rest of the show can sparkle(闪耀)—a show that is, as its chief manager Justin remarks, “not about Mars; this is an exhibition about people.”

Moving along, there is a quick yet clear flash through what the science-fiction writer Robinson calls “the history of Mars in the human mind”. A Babylonian clay tablet and a Greek vase speak to early ideas about the planet. A poster for the original Total Recall film reminds us of Mars’ psychological threat.

The main part of the show is our current plans for the Red Planet. There are real spacesuits and models of 3D-printed Martian settlements and suitable clothing and furniture. Mission architectures and engineering sketches line the walls. Real hammers meant for the International Space Station are wall-mounted beside a low-gravity table that has yet to leave, and may indeed never leave, Earth.

This, of course, is the great strength of approaching science through design: reality and assumptions can be given equal visual weight, drawing us into an informed conversation about what it is that we actually want from a future on Mars.
