LastPass Password strength has been a topic about the Internet lately. I have seen lots of clever methods for creating and remembering strong passwords. Some are better than others, but in my opinion, none are enough. Here's the problem: It doesn't matter how strong your passwords are if you use the same one on multiple sites. All it takes is for a site to get hacked, like Gawker media, or even Sony did, and now your super-strong password has been stolen, and every site on which you used that password has been accessed.

    Enter LastPass. It's not the only password manager out there, but I like it the best. You create ONE strong password that you have to memorize and use it to access you LastPass database. The LastPass database is stored online, on LastPass's services. LastPass recognizes the site you're on and automatically logs you in (after, optionally, asking you to re-enter your master password). LastPass also has automatic form fill and automatic password generation. This means that you can have a different, unique, very strong password for every site you log into, but you only have to remember one master password. It's the best of both worlds.

    One argument against LastPass is that if their database is attacked, then all of your sites are in danger, and that's true, but if their entire line of work is keeping that information safe, I'm willing to take that chance. The alternative is rolling dice（掷骰子） or picking phrases to create passwords, writing all of them down on a piece of paper or something, and then having to manually type them in when I go to a site. A terrible mess.

    There is a free version of LastPass, with some additional features unlocked if you pay a $12 a year subscription.

    New research brings some good news for lovers of spicy(辛辣的) foods, after finding that eating hot red chili peppers might help to extend lifespan（寿命）.

    Consuming hot red chili peppers might reduce death risk, say Chopan and Littenberg from the research team. In hot peppers, such as Mexico peppers, the strong flavor comes from a compound(复合物), which does not exist in sweet peppers or onions. Studies have suggested that this compound can offer a welth of health benefits.

    A study of more than 16,000 people in the United States revealed that individuals who consumed red chili peppers had a lower risk of death from all causes over an average of 18 years than those who did not eat the spicy food. Compared with participants who did not consume hot red chili peppers, those who did were found to be at 13 percent reduced risk of all-cause death.

    For example, a recent study reported by Medical News Today, found that the compound might have the potential to stop breast cancer, while an earlier study linked the compound to a reduced risk of digest system cancers. Still, the available data suggested that hot red chili pepper consumption was most strongly associated with a reduced risk of death from heart disease.

    While the researchers are unable to identify the concrete compound by which red chili peppers might extend lifepan, the team says that it is likely due to the compound that is effectively against obesity(肥胖症).

    Overall, the team says that these latest findings support those of the 2015 study, linking spicy food intake to reduced risk of death by showing “a significant decrease in death associated with hot red chili pepper consumption.” However, Chopan and Littenberg note that the earlier study was only conducted in Chinese adults, so the now research makes these findings more credible.

    Many non-edible (不能吃的), poisonous or otherwise not pleasant-tasting butterflies have distinct colors and pat terns. As a result, other more palatable (可口的)butterflies have evolved to mimic (模仿)those patterns to avoid being consumed by predators. There are several types of mimicry in butterflies: Bayesian mimicry, Müllerian mimicry, wasp (黄蜂)mimicry and tiger complex mimicry. Birds will con­sume unpalatable butterflies and associate their colors and patterns with the negative experience, thus avoiding the but­terflies performing mimicry. It is possible that birds even communicate their experience with other birds.

    Bayesian mimicry was established by the naturalist Hen­ry Walter Bates in 1862. He first observed that mimicry involved a palatable butterfly resembling an unpalatable, often toxic (有毒的)，butterfly. This mimicry will only work when the toxic model species outnumbers the non-toxic spe­cies. He believed that mimicry was the result of edible but­terflies producing mutations (突变)making them resemble their inedible cousins. This in turn resulted in the increased survival of the butterflies containing the mutation and resul­ted in the similarities between species. In 1879 another naturalist, Johann Friedrich Theodor Müller, observed that in some cases of mimicry both the mimic and the model are un­palatable. He considered this to be a cooperative mimicry and believed the species evolved side by side in a mutually benefi­cial relationship. If a bird tried to eat a member of either spe­cies, it would then avoid both. Wasp mimicry is similar to Bayesian mimicry, but instead of mimicking another unpalata­ble butterfly species, the mimic resembles a wasp to avoid predators.

    The tiger complex is a group of around 200 species of Neotropical butterflies that are involved in the most well-known form of mimicry. It is named such because the patterns of all of the included species are black on a background of either orange or yellow, resembling a tiger. In the com­plex are many unpalatable species, a few toxic species and a large number of completely edible species. Members of the tiger complex are all known for congregating (集合)in large groups that would normally be easy food for birds. Fortunately, birds have no interest in them due to their mimicry.

    Here are some exciting holidays to make your travel fun and a learning adventure.

    Salsa Dancing Holiday, Cuba

After nearly two months of relative silence among new waves ofCOVID-19 pandemic infection in Japan, organizers of Tokyo Olympics on Wednesday released the first of playbooks that will instruct athletes, officials and members of the news media on the procedures they must follow at the rescheduled Games.

Already delayed by a year, the opening ceremony is now a little more than 120 days away. Organizers must find a way to accommodate and ensure the safety of more than 10,000 athletes who view this summer as the result of years of sacrifice and training.

For now, the best that organizers could offer were the outlines of a plan. Athletes and other attendees will not be required to be vaccinated (接种疫苗) or to quarantine (隔离) on arrival in Japan, but they will be subject to severe restrictions on movement and socializing. All athletes will be required to test negative for COVID-19 within 72 hours of their departure for Japan and give in to another test on arrival.

The organizers said the documents were not an end. They would wait until spring to decide if audiences will be permitted to travel to Tokyo. If fans are eventually allowed to attend, the documents suggest they be asked to express support for athletes only in the form of clapping, rather than singing or chanting. To track outbreaks, visitors from abroad will have to file a list of everyone they have close contact with during that initial 14-day period.

Olympic officials see some reason for optimism. In many parts of the world, professional sporting events have been held for months, though often with very few or no spectators at all, and nothing as large as the Summer Games.
