1 . Many of our most worrying problems, from overeating to not saving enough for retirement to not working out enough have something in common: lack of self-control. Self-control is what gives us the capacity to say no to choices that are immediately satisfying but costly in the long term — that a piece of chocolate cake (instead of an apple), that afternoon in front of the couch (instead of a visit to the gym).
The problem of self-control has puzzled psychologists and behavioral scientists for decades. A great deal of research has identified situations in which self-control failures are likely to happen and tools to help people exercise better control.
Entrepreneurs have also become interested in self-control, as is evident from the many diet and exercise apps and gadgets on the market. To take one notable example, on the commitment contract website stickK.com, users put down some money (say, $200) and state a goal they want to achieve (such as to lose ten pounds in a month).
Tools like stickK.com can be effective, but they are often difficult to implement. My colleagues and I conducted a new research to point to a different solution that may be easier to carry out: using rituals.
A.They have to point out someone to monitor them and ensure they reach the goal or donate the money. |
B.Despite our best intentions, we often fail to meet our goals. |
C.Rituals are series of steps we take while attaching some kind of symbolic meaning. |
D.In the past, my colleagues and I have found that rituals reduce anxiety before stressful tasks, and improve performance. |
E.They also need to state what will happen to the money if they don’t stick to their commitments (e.g., it’ll go to a friend or to a charity they do not like). |
F.For instance, research has found that people persist for longer on tasks that require self-control when they know they’ll be paid for their efforts, or when they are told that their work will benefit others. |
3 . Animal products could produce electricity, one British power company warns — and to give consumers a choice, it's offering what it calls the world’s first vegan electricity.
Ecotricity, a renewable energy provider in the U.K., announced its electricity and gas would be certified vegan after it claimed half of British homes are powered by electricity made from animal byproducts. Company founder Dale Vince accused companies that consider themselves “ethical” or “green” of keeping consumers in the dark about their “secret ingredient.” “We need clear labeling of energy sourcing so that people can make informed choices,” he said in a statement.
The company offers “vegan energy” in wind and solar power, and it’s developing “sea power” produced by wave oscillation and marine currents. None of Ecotricity’s electrical sources contains animal byproducts that the company knew of before it made the announcement, but it registered with the Vegan Society to certify its green status.
Though not widely disclosed, it’s fairly common for power companies to derive electricity from animals through anaerobic digestion (厌氧消化). Animal waste is generally considered a clean, renewable energy source. Turning manure into fuel eliminates a sizeable chunk of carbon pollution and lessens power companies’ reliance on “dirtier” fossil fuels like coal and oil. Plus, animals provide a limitless supply of waste, while Earth’s natural gas stores are finite, so crackers wouldn’t need to drill into rock to extract it.
Cows are pictured at a Wagyu cattle breeding center in June in Petit-Mars, France. A U.K. energy company announced the first “vegan electricity” after warning consumers about animal byproducts in energy production.
After anaerobic digestion, farmers can use the liquid remains of the manure as fertilizer and make chips for animal bedding from the solid leftovers, chemical engineer David Simakov told Popular Science.
“We are talking about producing the amount of renewable natural gas enough to heat thousands of homes from just a single large landfill site,” he said. “We need to stop pumping carbon from underground into the atmosphere and start caring about introducing more and more renewable energy to make our lives more sustainable.”
Renewable energy only accounts for 11 percent of energy consumption in the U.S., according to the Energy Information Administration. Fossil fuels and nuclear energy generate more than 80 percent of the country’s electricity, and that’s unlikely to change: like other clean energy sources, anaerobic digestion is still more expensive than traditional sources of energy.

In China, treatment rates of mental disorders are low, which is partially linked to a shortage of trained professionals. World Health Organization data show China’s concentration of psychiatrists is four times lower than the global average, with only 2.2 per 100,000 people (the U.S. rate is 10.5). Another reason for low treatment rates is
