Why can’t we stop the common cold? According to Peter Barlow, a scientist at Edinburgh Napier University, the main challenge lies in the many different types of cold viruses that are produced by the rhinoviruses (鼻病毒). There are at least 160 types. They change so easily that they quickly become resistant to drugs. In other words, a single cure isn’t likely to work on every type of cold.

However, researchers from Stanford University have found a possible answer. They discovered a protein that the viruses need. Without it, they can't spread inside your body.

To identify the gene which produces the specific protein needed by the viruses, researchers used a gene-editing technique to test all genes one by one for thousands of cells. These modified (改变的) cells were then exposed to a range of rhinoviruses which cause the common cold.

All the viruses were unable to copy inside cells without a gene that produces a specific protein, called methyltransferase (甲基转移酶) SETD3.

Then, they tested genetically modified mice, which were completely unable to produce the protein. The mice were able to live healthy, normal lives without the protein.

“Lacking that gene protected the mice completely from the common cold,” associate professor Jan Carette, from Stanford, told the BBC.

“These mice would always die, but they survived and we saw a very strong protection.”

Carette said the plan is to find a drug which can keep back the protein for a limited time, rather than produce genetically modified humans.

“We have identified a fantastic target that all rhinoviruses require and depend on. Take that away and the virus really has no chance,” said Carette.

The “Twenty-four Solar terms” is the Chinese 【1】(tradition)way of dividing and marking time.

For decades, sociologists have been trying to understand why certain people rise to the top of their fields. A number of theories have emerged, so if you're struggling on the path of success, perhaps these will give you some new clues.

IQ is Overrated

A high IQ is necessary, but it is not adequate to predict executive competence and corporate success. While people with high test scores do have more opportunities, that doesn't mean that smart people are more successful. In fact, in many fields the link between success and intelligence is often weak or non-existent. Nobel Prize winning Israeli-American psychologist, Daniel Kahneman, found that people would rather do business with a person they like and trust rather than someone they don’t, even if the likeable person is offering a lower quality product or service at a higher price.

The 10,000 Hours Theory

A Professor at the University of Colorado named Anders Ericsson decided to look at the differences between amateurs and professionals. In 1993, he released a paper that found on average amateurs only got about 4000 hours of practice, but professionals had practiced for at least 10,000 hours. While there's some debate over whether 10,000 hours is a rule or just a theory, many experts agree that a significant number of people who are considered "great" have, on average, 10,000 hours of experience.

Deliberate Practice

If no one is born talented and you need 10,000 hours of practice, what's the most effective way of using those hours? One theory is something sociologists call "deliberate practice." Essentially, there are six elements. The practice needs to be meant to specifically improve performance, and is even more effective if there's coaching. It needs to be repeatable, and feedback regularly is crucial. It also has to be demanding, either physically or mentally. If you're doing all of this correctly, it shouldn't be a fun experience. An example would be a basketball player who isn't very good at free throws spending hours and hours just doing free throws while being coached. Not a great time no matter how big of a basketball fan you are.

No One Succeeds on Their Own

While it would be nice to succeed simply because we work hard, life doesn't work that way. We need help and support from friends, family and teachers, and then we need chances from employers and other key figures in the fields we choose to pursue. In order to succeed, the gifts and interests of a person need to be encouraged, especially at a young age. Then as they grow up, people need to be given opportunities, breaks and second chances. Without help from other people, it makes it impossible to succeed because as Gladwell points out, "… no one—not rock stars, not professional athletes, not software billionaires, and not even geniuses — ever makes it alone."

You Have Amazing Potential

On average, the human mind can remember a sequence of seven to nine numbers. After that it becomes incredibly hard to remember all the numbers in the right order. Researchers at Carnegie Mellon University wanted to know if someone of average intelligence could break that barrier with practice. Through a lot of tests, researchers discovered what they called "the remarkable potential of 'ordinary' adults and their amazing capacity for change with practice." Their research showed that even "ordinary" people have the potential to be great by challenging themselves. If you work hard, your goals can be more attainable than you thought.

A hangover refers to the headache and sick feeling that you have the day after drinking too much alcohol. If you are looking for something to nurse your hangover, you will find the following right ideas.

1. ASIAN PEAR JUICE

Have some extra Asian pears at home? Run them through your juicer before your next night out. According to researchers at Australia’s Commonwealth Scientific and Industrial Research Organization, just 7.4 ounces of Asian pear juice is enough to soften the blow of a hangover. The scientists say that the juice interacts with enzymes that break down alcohol, speeding up your metabolism and leaving less surplus alcohol for your body to absorb. There’s just one catch: The juice must be consumed before you drink anything else in order to be effective.

2. MUSIC

Anyone who’s ever suffered through a massive hangover knows that sound is the enemy. But while your roommate’s 9 a.m. tap dancing practice might exacerbate (加剧) your symptoms, music may have the opposite effect. Research has shown that listening to music can provide relief to migraines, which are similar to hangover headaches. As long as the music is pleasant and suits your taste, it should help to drown out the chorus of pain laying in your mind. Head sensitivity isn’t the only symptom music helps with. According to researchers at the University of Edinburgh, listening to your favorite music also eases pain.

3. EGGS

The best way to tackle a hangover with food is to eat while you drink. Chowing down after the damage has already been done may distract you from your turmoil for a short while, but it won’t soothe your physical symptoms. There are a few exceptions: Eggs, for example, have hangover-fighting potential thanks to a special ingredient. The food is packed with cysteine, an amino acid that breaks down the drinking byproduct acetaldehyde (乙醛). So whether you prefer to enjoy brunch out or at home, make sure your meal includes eggs in some form.
