Your Dog: Optimist or Pessimist?
"Scientists have shown what many dog owners have suspected—while some canines are joyfully optimistic about life, others have a tendency for gloomy pessimism."
"A study has found that dogs can be divided into two personality types based on their emotional outlook. 'Bowl-half-full' types are full of hopeful optimism, while their 'bowl-half-empty' kennelmates tend to expect the worst. The researchers believe they have shown scientifically for the first time that dogs experience the same sort of emotional states as people who are faced in similar half-full or half-empty scenarios. Dogs who are more pessimistic are also more likely to suffer other kinds of behaviour disorders, such as chewing up the furniture or howling uncontrollably when their owners leave them alone at home, the scientists said."
In a breakthrough for nuclear fusion research, scientists at China's Experimental Advanced Superconducting Tokamak (EAST) reactor have produced temperatures necessary for nuclear fusion on Earth.
- The EAST reactor was able to heat hydrogen to temperatures exceeding 100 million degrees Celsius.
- Nuclear fusion could someday provide the planet with a virtually limitless supply of clean energy.
- Still, scientists have many other obstacles to pass before fusion technology becomes a viable energy source.
Military recruits are supposed to be assessed to see whether they're fit for service. What happens when they're not?
- During the Vietnam War, Robert McNamara began a program called Project 100,000.
- The program brought over 300,000 men to Vietnam who failed to meet minimum criteria for military service, both physically and mentally.
- Project 100,000 recruits were killed in disproportionate numbers and fared worse after their military service than their civilian peers, making the program one of the biggest—and possibly cruelest—mistakes of the Vietnam War.
