1 . Google has announced plans to stop supporting tools designed to follow Internet users across the web in order to target them with specific advertising.
Such tools are known as cookies-small data files that are stored on an Internet user's computer as they browse （浏览）different websites. This data can be read by web servers to identify web browsing behaviors of the user. Cookies make it possible for users to avoid having to repeatedly enter their user names and passwords to get access to websites they use often. But the use of cookies raises major privacy concerns, with critics saying a user's browsing history should not be recorded just to target them with ads.
Google announced in 2020 it had decided “to remove support for third-party cookies" from its Chrome browser. In another online announcement, Google repeated this promise, saying it will not build new tools to replace current cookie technology.
In explaining its decision, Google referred to a Pew Research study that found 72 percent of Americans feel that almost all of what they do online is tracked by advertisers. Google's decision to remove third-party cookies also followed increasing efforts to protect privacy in Europe and the United States. Google said the current Internet advertising model needs to change to answer “the growing concerns people have about their privacy and how their personal identity is being used.”
In January, however, Google's plan was questioned by British competition regulators. The country's Competition and Markets Authority announced it had launched an investigation into whether the changes would give Google an unfair advantage over competitors in Internet advertising. The agency said it received objections to the plan from Marketers for an Open Web, a league of technology and publishing companies. The group accuses Google of “abusing its dominant position” by attempting to create a new advertising model.
In its latest statement, Google said, “We will not build alternate identifiers to track individuals as they browse across the web, nor will we use them in our products.”

2 . Humans’ overconsumption of resources is a leading contributor to global climate change, says University of Arizona researcher Sabrina Helm. Therefore, it’s increasingly important to understand the choices consumers make and how those decisions affect the health of a planet with limited resources. In a new study, published in the journal Young Consumers, Helm and her colleagues explore how materialistic values influence pro-environmental behaviors in millennials, who are now the nation’s most influential group of consumers.
The researchers focused on two main categories of pro-environmental behaviors: reduced consumption, which includes actions like repairing instead of replacing older items; and “green buying,” or purchasing products designed to limit environmental impacts. The researchers also looked at how engaging in pro-environmental behaviors affects consumer well-being.
More materialistic participants, the researchers found, were unlikely to engage in reduced consumption. However, materialism did not seem to have an effect on their likelihood of practicing “green buying.” That’s probably because “green buying,” unlike reduced consumption, still offers a way for materialists to fulfill their desire to get new items, Helm said.
Study participants who reported having fewer materialistic values were much more likely to engage in reduced consumption. Consuming less was, in turn, linked to higher personal well-being and lower psychological suffering. Green buying—which may have some positive environmental effects, although to a smaller degree than reduced consumption—was not found to improve consumer well-being, Helm said.
The take-home message for consumers: “The key is to reduce consumption and not just buy green stuff. Having less and buying less can actually make us more satisfied and happier,” Helm said. “If you have a lot of stuff, you have a lot on your mind,” she said. “For example, it requires maintenance and there’s a lot of burdens of ownership, and if you relieve yourself of that burden of ownership, most people report feeling a lot better and freer.”
Helm and her colleagues additionally looked at how materialism affects millennial consumers’ proactive financial behaviors, such as budgeting and saving. Examining financial behaviors alongside pro-environmental behaviors provides a picture of how young adults proactively deal with resource limitations in two contexts: environmental and financial, Helm said.
As expected, Helm and her colleagues found that those who reported having more materialistic values engaged in fewer proactive financial behaviors than their less materialistic counterparts (对应的人). The researchers also found that, consistent with previous studies, proactive financial behaviors were associated with better personal well-being, life satisfaction and financial satisfaction, as well as lower psychological suffering.
Understanding how materialistic values impact consumer behaviors, and how those behaviors in turn affect personal and environmental well-being, is important, Helm said. However, she acknowledges that for many consumers, shifting behaviors to be more financially proactive and consume less will be challenging.

3 . Immersive Van Gogh
From the creators of the blockbuster show in Paris seen by over two million visitors and still wowing crowds in Toronto, the west coast premiere (首场) of the Immersive Van Gogh Exhibit will bring the art of Vincent to life in Los Angeles.
Immersive art is not just a technical way to represent video and audio in huge spaces. The word immersive indicates a deep commitment of intentions which connect images and sounds in a way that the audience is able to experience a different way of the art.
True to its name, this exhibition transforms the iconic (偶像的) paintings of Vincent van Gogh into moving, wall-filling projections. “Immersive Van Gogh” promises half-a-million cubic feet of projections that pull from some of the post-impressionist’s most recognizable pieces, including The Bedroom, Sunflowers and, yes, The Starry Night.
You will experience art like never before—lose yourself in entrancing, moving images that highlight brushstrokes, detail, and color—truly illuminating (照亮) the mind of the genius.

4 . Blood-Doping Champion
Blood doping (违规输血) to improve performance is forbidden in professional sports. Athletes can use this technique to fuel their muscles with more oxygen-carrying red blood cells—for example, by receiving a transfusion. But many animals dope naturally: sheep, fishes and horses can boost their blood’s capacity to carry oxygen by 16 to 74 percent in physically demanding situations. Now a study shows that an Antarctic fish called the bald notothen can increase its carrying capacity by more than 200 percent to pursue an active life in cold waters.
Like most fishes native to Antarctica, the bald notothen’s blood contains anti-freeze proteins that help it withstand extreme cold. But these proteins, along with red blood cells (RBCs), can make blood sticky and hard to circulate. Some Antarctic fishes adapt by removing RBCs altogether, absorbing oxygen directly from the water via skin as they passively await prey (猎物). Bald notothens, however, actively swim below surface ice to chase other active life when avoiding seals and penguins. For this behavior, “you need to supply more oxygen to the muscles,” says Michael Axelsson, a physiologist at the University of Gothenburg in Sweden and co-author of the new study.
The scientists compared RBC levels in samples collected from bald notothens relaxing in glass tanks with those in samples drawn from fish they “chased” using a plastic tube. RBC levels were at 9 percent in the resting animals but 27 percent in the exercised ones, showing a 207 percent increase in the latter’s blood oxygen carrying capacity. “No other fish we’ve seen can more than double their RBCs or drop their numbers to such a low level when resting,” Axelsson says. The fish’s spleen (脾) stores RBCs, and the researcher found that to release more into the bloodstream, the organ shrinks to weigh 41 percent less.
The enormous changes in RBC levels initially surprised Gerald Kooyman, a biologist at the Scripps Institution of Oceanography, who was not involved in the study. He notes, however, that these animals have fewer blood cells to begin with, so maintaining circulation with a tripled RBC count is less difficult. If a diving Weddell seal pushed its RBC levels from 40 to 90 percent, for instance, its blood would be dangerously hard to pump.
Yet bald notothens do face trade-offs for their ability. The scientists found blood pressure was 12 percent higher and the heart worked 30 percent harder in active individuals. Bald notothens can rest during quiet times, but when they need to use their abilities, Axelsson says, “these fish have to live with more RBCs because they need more oxygen.”

5 . In 1997, a group of twenty British women made history. Working in five teams with four women in each team, they walked to the North Pole. Apart from one experienced female guide, the other women were all ordinary people who had never done anything like this in their lives before. They managed to survive in an environment which had defeated several very experienced men during the same period.
Once on the ice, each woman had to ski along while dragging a sledge (雪橇) weighing over 50 kilos. This would not have been too bad on a smooth surface, but for long stretches (一片地域), the Arctic ice is pushed up into huge piles two or three meters high and the sledges had to be pulled up on side and carefully let down the other so that they didn’t crash. The temperature was always below freezing point and sometimes strong winds made walking while pulling so much weight almost impossible. It was also very difficult to put up their tents when they stopped each night.
In such conditions the women were making good progress if they covered fourteen or fifteen kilometers a day. But there was another problem. Part of the journey was across a frozen sea with moving water underneath the ice and at some points the team would drift (漂流) back more than five kilometers during the night. That meant that after walking in these very terrible conditions for ten hours on one day, they had to spend part of the next day covering the same ground again. Furthermore, each day it would take three hours from waking up to setting off and another three hours every evening to set up the camp and prepare the evening meal.
So, how did they manage to succeed? They realized that they were part of a team. If any one of them didn’t pull her sledge or get her job done, she would endanger the success of the whole expedition (远征探险). Any form of selfishness could result in the efforts of everyone else being completely wasted, so personal feelings had to be put to one side. At the end of their journey, the women agreed that it was mental effort far more than physical fitness that got them to the North Pole.

6 . Sleeping is important, but we all know that, right? Many people have experienced strange sleeping patterns, unusual dreams and a feeling of restlessness and sleepiness during the coronavirus lockdown, despite a good night's sleep. So what sort of things can help you to improve your sleep?
Wrong Habits
Many myths related to sleep can be quite damaging for our health. Former British Prime Minister Margaret Thatcher famously claimed that she only hit the sack for five hours a night. But according to experts this is harmful to health.
Likewise, falling asleep in front of the TV is another thing to avoid. The bright lights can prevent you from entering deep sleep.
Wrong Ways to Help Go to Sleep
From a young age we're told to count sheep to help us to nod off, with some choosing to stay in bed to battle with insomnia（失眠）.However, some experts advise getting up and doing something mindless, like folding socks, to help us get in the mood to catch forty winks.
Psychologist Seth J. Gillihan PhD recommends walking to help in the battle against insomnia. He talks about a sleep study published in the journal Sleep Health which suggests that those who walk slightly more will experience better quality and duration of sleep. Watching what you eat or drink can also improve the amount of REM, or rapid eye movement you experience.
Snoring Can be dangerous
If you're a snorer, you might also want to take note. While most breathing noisily is harmless, it could be a sign of sleep apnoea,（睡眠呼吸暂停）with people suffering from the condition more likely to have strokes or heart attacks, irregular heartbeats or high blood pressure.
A Short Sleep during the Day May Refresh You
Finally, a decent nap, or even a power nap, can help you to be more alert, calm and focused. So while there are some good tips like exercising or folding socks to help us get a good night's sleep, sometimes a good afternoon's sleep can help us deal with the day ahead.

7 . There’re currently 21.5 million students in America, and many will be funding their college on borrowed money. Given that there’s now over $1.3 trillion in student loans on the books, it's pretty clear that many students are far from sensible. The average student’s debt upon graduation now approaches $40, 000, and as college becomes ever more expensive, calls to make it “free” are multiplying. Even Hillary Clinton says that when it comes to college, “Costs won’t be a barrier.”
But the only way college could be free is if the faculty and staff donated their time, the buildings required no maintenance, and campuses required no utilities. As long as it's impossible to produce something from nothing, costs are absolutely a barrier.
The actual question we debate is who should pay for people to go to college. If taxpayers are to bear the cost of forgiving student loans, shouldn’t they have a say in how their money is used?
At least taxpayers should be able to decide what students will study on the public dime. If we're going to force taxpayers to foot the bill for college degrees, students should only study those subjects that are of greatest benefit to taxpayers. After all, students making their own choices in this respect is what caused the problem in the first place. We simply don’t need more poetry, gender studies, or sociology majors. How do we know which subjects benefit society? Easy.
Average starting salaries give a clear indication of what type of training society needs its new workers to have. Certainly, there’re benefits to a college major beyond the job a student can perform. But if we’re talking about the benefits to society, the only thing that matters is what the major enables the student to produce for society. And the value of what the student can produce is reflected in the wage employers are willing to pay the student to produce it.
A low wage for elementary school teachers, however, doesn’t mean elementary education isn’t important. It simply means there’re too many elementary school teachers already.
Meanwhile, there’re few who’re willing and able to perform jobs requiring a petroleum engineering major, so the value of one more of those people is very high.
So we can have taxpayers pick up students’ tuition in exchange for dictating what those students will study. Or we can allow students both to choose their majors and pay for their education themselves. But in the end, one of two things is true:
Either a college major is worth its cost or it isn’t. If yes, taxpayer financing isn’t needed. If not, taxpayer financing isn’t desirable. Either way, taxpayers have no business paying for students’ college education.
1. What does the author think of college students funding their education through loans?| A．They only expect to get huge returns. |
| B．They are acting in an unwise way. |
| C．They benefit at taxpayers’ expense. |
| D．They will regret doing so someday. |

8 . Masks that helped save lives during the coronavirus pandemic(流行病) are proving a deadly danger for wildlife, with birds and marine creatures trapped in the incredible number of abandoned facial coverings littering on animal habitats.
Single-use surgical masks have been found thrown around pavements, waterways and beaches worldwide since countries began demanding their use in public places to slow the pandemic's spread. Macaques(猕猴) have been spotted chewing the straps(带子) off old and deserted masks in Malaysia a potential choking danger for the little monkeys. And in an incident that captured headlines in Britain, a gull(海鸥) was rescued in the city of Chelmsford after its legs became tangled（缠结）in the straps of a disposable mask for up to a week. The animal welfare charity was alerted after the bird was spotted motionless but still alive, and they took it to a wildlife hospital for treatment before its release.
The biggest impact may be in the water.More than l. 5 billion masks made their way into the world's oceans last year. accounting for around 6,200 extra tons of marine plastic pollution, according to environmental group OceansAsia. ? Already there are signs that masks are worsening threats to marine life. Conservationists in Brazil found one inside the stomach of a penguin after its body was washed up on a beach, while a dead pufferfish(河豚) was discovered caught inside another off the coast of Miami.
Masks and gloves are "particularly problematic" for sea creatures，says George Leonard, chief scientist from U. S. -based NGO Ocean Conservancy. "When it takes those plastics hundreds of years to break down in the environment, they form smaller and smaller particles," he added, "those particles then enter the food chain and impact entire ecosystems."
Fortunately, there has been a shift towards greater use of reusable cloth masks as the pandemic has worn on，but many are still choosing the lighter single- use varieties.Campaigners have urged people to throw away them properly and remove the straps to reduce the risk of animals becoming trapped. Oceans Asia has also called on governments to increase fines for littering and encourage the use of washable masks.

9 . Great Barrier Reef Choking on Pollutants
Attempts to protect the Great Barrier Reef are failing. A report released Monday by the government in Australia says water quality in the Great Barrier Reef is far below what it should be. It showed that pollution have decreased, but not enough to reach environmental targets.
Sediment (沉淀物) and chemicals can weaken coral, hurting its ability to feed and grow. Coral are live animals that take root in the ocean floor, but they are not plants. Reefs are the hard skeletons (骨架) left at the bottom of the sea by small marine creatures called polyps (珊瑚虫). The polyps then form the larger structure of a reef. Corals also are some of the most diverse ecosystems on the entire planet. They can make a home for invertebrates, crustaceans, fish, and sea snakes.
Steve Miles is Queensland’s environment minister. He says the research shows the Reef needs more protection. “Over that five-year period, we did see some progress towards our targets. Sediment is down 12 percent and pesticides (杀虫剂) loads are down 30 percent. But what is most disturbing is that these results are far from our targets. Progress towards these targets flat-lined in the period 2013-2014. If one of my kids came home with a report card like this, I would be a bit disappointed. There is more bad news here than good news. ” said Steve Miles.
The report also found that fewer than one-third of Queensland’s sugar plantations used techniques to reduce the use of pesticides. Only 28 percent of land managers managed their land properly. They had reduced harmful water run off to protect the health of the Reef. The official target is a 90 percent reduction in pesticide use within three years.
Scientists at the University of Queensland and the Australian Institute of Marine Sciences published their findings Wednesday, July 18 in the journal Science Advances. It found between 1992 and 2010, the recovery rate dropped by an average of 84 percent. But there is hope. The study also found some corals can recover quickly if “acute and chronic stressors” are lessened.
Meanwhile, the Australian government released its updated reef protection plan Friday. It clearly states global temperatures must be stopped from rising in order to save the world’s largest living structure.

10 . In a study published in Nature Machine Intelligence, researchers at Ohio State University show how artificial intelligence（AI）can follow clinical trials to identify drugs for repurposing, a solution that can help advance innovative treatments.
Repurposing drugs is legal and not unusual. When doctors prescribe(开处方)drugs that have been approved by the Food and Drug Administration(FDA)for purposes different from what is printed on the labels, the drugs are being used “off-label” Just because a drug is FDA-approved for a specific type of disease does not prevent it from having possible benefits for other purposes.
For example, Metformin, a drug that is FDA-approved for treating type 2 diabetes, is also used to treat PCOS(a disease of women), and other diseases. Trazodone, an anti-depressant with FDA-approval to treat depression, is also prescribed by doctors to help treat patients with sleep issues.
The Ohio State University research team created an AI deep learning model for predicting treatment probability with patient data including the treatment, outcomes, and potential confounders(干扰因素).
Confounders are related to the exposure and outcome. For example, a connection is identified between music festivals and increases in skin rashes(红疹). Music festivals do not directly cause skin rashes. In this case, one possible confounding factor between the two may be outdoor heat, as music festivals tend to run outdoors when the temperature is high, and heat is a known cause for rashes. When working with real-world data, confounders could number in the thousands. AI deep learning is well-suited to find patterns in the complexity of potentially thousands of confounders.
The researcher team used confounders including population data and co-prescribed drugs. With this proof-of-concept, now clinicians have a powerful AI tool to rapidly discover new treatments by repurposing existing medications.
