A recent study, while showing a generally positive attitude toward science, also suggests a widespread worry that it may be "running out of control". This idea is dangerous.

    Science can be a force for evil as well as for good. Its applications can be channeled either way, depending on our decisions. The decisions we make, personally or collectively, will determine the outcomes of science. But here is a real danger. Science is advancing so fast and is so strongly influenced by businesses that we are likely to believe whatever decisions we come to will make little difference. And, rather than fighting for the best possible policies, we may step back and do nothing.

    Some people go even further. They say that despite the moral and legal objections, whatever is scientifically possible will be done-somewhere, sometime. They believe that science will get out of control in the end. This belief is dangerous too, because it fuels a sense of hopelessness and discourages then from making efforts to build a safer world.

    In our interconnected world, the lack of agreement in and out of the world of science can lead to the failure to control the use of science. Without a common understanding, the challenges of "controlling" science in this century will be really tough. Take human cloning for example. Despite the general agreement among scientists on its possible huge impact on traditional moral values, some countries still go ahead with the research and development of its related techniques. The outcomes are hard to predict.

    Therefore, discussions on how science is applied should be extended far beyond scientific societies. Only through the untied efforts of people with hope, can we be fully safe against the misuse of science and can science best serve mankind in the future.

    How fit are your teeth? Are you lazy about brushing them? Never fear: An inventor is on the case. An electric toothbrush senses how long and how well you brush, and it lets you track your performance on your phone.

    The Kolibree toothbrush was exhibited at the International Consumer Electronics Show in Las Vegas this week. It senses how it is moved and can send the information to an Android phone or iPhone via a Bluetooth wireless connection.

    The toothbrush will be able to teach you to brush right (don't forget the insides of the teeth!) and make sure you're brushing long enough. “It's kind of like having a dentist actually watch your brushing on a day-to-day basis,” says Thomas Serval, the French inventor.

    The toothbrush will also be able to talk to other applications on your phone, so developers could, for instance, create a game controlled by your toothbrush. You could score points for beating monsters among your teeth. “We try to make it smart but also fun,” Several says.

    Serval says he was inspired by his experience as a father. He would come home from work and ask his kids if they had brushed their teeth. They said “yes,” but Serval would find their toothbrush heads dry. He decided he needed a brush that really told him how well his children brushed.

    The company says the Kolibree will go on sale this summer, for $99 to $199, developing on features. The U.S. is the first target market.

    Serval says that one day, it'll be possible to replace the brush on the handle with a brushing unit that also has a camera. The camera can even examine holes in your teeth while you brush.

    An Israeli law banning too skinny models went into effect with the start of 2013. The law, approved last March in Israel, requires models to prove they have maintained a Body Mass Index (BMI) of at least 18.5 for three months before a fashion show. That means a woman who is 68 inches tall can weigh no less than 119 pounds.

    "This law is another step in the war against eating disorders," said physician Adatto. "Underweight models," he explained, "can no longer serve as role models for innocent young people who copy their false image of being skinny."

    But some critics in this country say it is misguided, focusing on weight instead of health. They also say the Israeli ban is bound to fail because of the strong power of the fashion industry. "I think it's an approach that isn't going to work." said eating disorder expert Susan Ice, who worked with an organization which creates a healthy working environment for models.

    But Adatto told the reporter that he began to concern the issue after meeting an ambitious model who looked like she needed to be hospitalized. He said. "I realized that only legislation(立法) can change the situation. There was no time to waste; so many girls were dieting to death."

    However, the efforts to regulate models' weight in Spain and Italy have not resulted in significant changes in part because of difficulties in determining reliable methods of measuring weight and health.

    Still, folks including Ice say there's no denying that images from Hollywood and the fashion industry can be difficult for young women to deal with. "Certainly I don't believe the modeling industry has caused the rise in eating disorders, but it makes it harder," she says. "It's a difficult recovery environment, worshiping thinness as the beauty ideal."

    Scientists think that growing garden grass could be the secret to solving our energy needs, and we may soon be able to replace our gasoline with "grassoline".

    The team, including experts from Cardiff University in Wales, has shown that hydrogen can be taken from grass in useful amounts with the help of sunlight and a cheap catalyst(催化剂) —something that speeds up a chemical reaction without being used up.

    It is the first time that this has been shown and it could lead to a sustainable(可持续的) way of making hydrogen, reported Asian News International. This could be an important kind of renewable energy because it is high in energy and it does not give out harmful gases when it is burned.

    Study co-author Michael Bowker said, "This is really a green source of energy. Hydrogen is seen as an important future energy carrier as the world moves from fossil fuels to renewable energy, and our research has shown that even garden grass could be a good way of getting it."

    Cellulose(纤维素), which is a key part of plants and the biopolymer(生物聚合物) found in the largest numbers on the earth, could be a great source of hydrogen.

In its study, the team looked at the possibility of getting hydrogen from cellulose using sunlight and a simple catalyst.

    This is called photocatalysis(光催化作用) and in it, the sunlight starts the catalyst, which then makes cellulose and water into hydrogen. The researchers studied the effectiveness of three metal-based catalysts, of which nickel(镍) especially interested the researchers, as it is a much more common metal than gold and palladium(钯) and it saves more money.

    According to Bowker, producing hydrogen from cellulose using photocatalysis has not been studied in detail. The team's research shows that large amounts of hydrogen can be produced using this method with the help of a bit of sunlight and a cheap catalyst.

    The study shows that it is effective to use real grass taken from a garden. "This is important as it avoids the need to separate and clean up cellulose, which can be both difficult and costly," said Bowker.

A surprising new research from Auckland University of Technology (AUT), New Zealand contradicts the commonly held view that surfers are folks only focused on their own fun. Instead, they often play an important role in saving lives. The research reveals that these thrill seekers selflessly save people they see struggling in the ocean as swimmers or after boating incidents, and so actually reduce deaths from drowning (溺水), playing a key role in making beaches safer. 

According to the World Health Organization, an estimated 236,000 people drown worldwide each year, with drowning the third leading cause of unintentional death. 

However, according to a survey, at the heart of the research, life-saving acts of heroism by surfers who save others in difficulty in the ocean waters around them, are surprisingly common. In fact, based on the sample of 418 surfers, respondents reportedly rescue an average of three people drowning or struggling in the water over the course of their lives, and some even report taking part in 10 to 20 rescues. This makes surfers the under-recognized guardians of the beach rather than the self-centered images shown in movies like Fast Times at Ridgemont High, or Point Break. 

In addition, the survey found that in almost 90 percent of rescues, people aided by the responding surfers required no further treatment after the incident, making their help unlikely to be reported and so recorded, As one of the survey's co-authors Jamie Mead says, "We need to get surfers the recognition they deserve and do more research to accurately quantify (用数量表述) how many rescues they're actually doing."

Since this research was published, there has been a growing interest in the training of surfers in life-saving skills. Sonia Keeper, an experienced surfer and instructor, explains that the insights provided by the survey have motivated surfing organizations to expand their reach and connect with an even broader community of surfers. "If life-saving skills are rolled out (正式推出) to the broader coastal surfer communities around the world, this preparation can help ensure that a good day at the beach doesn't turn into a sad one," she adds.
