Here's an idea whose time has come: A flu shot that doesn't require an actual shot.

    For the first time, researchers have tested a flu vaccine patch (疫苗贴) in a human clinical trial and found that it delivered as much protection as a traditional injection with a needle. Doctors and public health experts have high hopes that it will increase the number of people who get immunized (免疫的) against the flu.

    Seasonal flu is responsible for up to half a million deaths around the world each year according to the World Health Organization. A team led by Georgia Tech engineer Mark Prausnitz has come up with an alternative method that uses “microneedles”. These tiny needles are so small that 100 of them, arranged in order on a patch, can fit under your thumb (拇指).Yet they're big enough to hold vaccine for three types of flu.

    None of the study volunteers had serious side effects. The groups that got patches had mild skin reactions that were not seen in the regular needle group, while the volunteers in the regular needle group were more likely to experience pain. Overall, 70 percent of the volunteers who got vaccine patches said they'd rather use them again than get a traditional flu shot. The study authors declared it a success on all fronts.

    The biggest beneficiaries could be people in low- and middle-income countries, where flu vaccines are hard to come by. Reducing pain is nice, but other benefits—the patch costs less，is easier to transport, doesn't require refrigeration, can be self - administered and doesn't cause waste of needles—are even better.

    “Microneedle Patches have the potential to become ideal candidates for vaccination programs,” wrote Katja Hoschler and Maria Zambon of Public Health England.

    OK, so it's not a real war but the U. S. and China are at the beginning of a trade war thanks to President Trump's policy. The Chinese government raised $34 billion in new duties on goods exported from the U.S. last week in answer to President Trump's unwise tariffs(关税) of $34 billion on Chinese goods.

    Farm and seafood-producing states are going to be hit hardest by China's new tariffs on U. S. goods. States where cars are made and shipped to China are on the hook as well.

    In terms of value, some 38 percent of products on the tariff list are agricultural, including soybeans, sorghum, tobacco and meat. That's nothing like good news for farm-belt states, primarily in the Midwest like Iowa.

    A wide range of seafood is on China's tarifflist. That could hurt fishery workers in Alaska and lobster(龙虾) harvesters in Maine. Alaska, for example, exported nearly $lbillion worth of seafood to China. "China is a major market for Alaska seafood," said Alexa Tonkovich, Executive Director of the Alaska Seafood Marketing Institute. "The seafood industry directly employs nearly 60,000 workers in Alaska each year and directly employs more workers than any other private industry."

    And automaking States, particularly in the South, are also at risk. Some 24 percent ofproducts on the list- in terms of value-are cars, trucks and other vehicles. Michigan alone exported $1.7 billion worth of motor vehicles and vehicle parts to China in 2017. Other states being affected include South Carolina, where BMW makes SUVs for both the U.S. and export, and Alabama, home to Mercedes-Benz, Toyota, Honda and Hyundai factories.

    This round of tariffs spares some industries, like commercial aircraft. Washington State could breathe a sigh of relief, which is home to Boeing. It also, for the moment, skips tariffs on chemical products.

    Alexa Tonkovich has warned the U.S. government that the trade war could risk jobs, reduce industry profits, and cause higher prices for consumers in the U.S!

Doing crosswords(纵横字谜) is a fun way to kill the time and can also be educational. Difficult crosswords may leave you confused as you have no ideas on how to solve them sometimes. To perform well in this game, you need to have enough knowledge of different fields. If you are unable to do them and you have access to the answers, it is not generally considered cheating to look up an answer or two. However, in some cases, it does not follow the rule.

A crossword should not include someone else's answers, so even a quick look at a fellow student to complete a crossword would not be fair. Generally, you wouldn't have access to the answers.

Additionally, some crossword competitions should not be connected with cheating. Again, in such a situation, you usually won't have access to the answers. Turning to the Internet or referring to(查阅) any books of crosswords for answers is also unfair, since some people will complete the crosswords strictly with their own knowledge.

If you are not in a competitive environment, the check of a word can actually be an opportunity to learn how to become better at crosswords. Through looking up the answers (Although sometimes considered as cheat.), you can memorize whatever facts or word definitions (定义) you must look up. This will help you avoid the need to cheat in the future.

Some argue that cheating on crosswords is always wrong, and you're only cheating yourself if you are looking up the answers. It could be argued instead that cheating on crosswords that are done for fun or enjoyment can actually be an opportunity to benefit yourself because you're learning something new. Just don't forget to mention that you actually did cheat a little. Being honest is of great importance both to you and the other competitors.

It can be helpful to buy books of crosswords that have several different difficulty levels. If you are new to doing crosswords, you might want to put off working on crosswords until you are more confident in your skills.

We're often told "laughter is the best medicine".Laughter is ancient and instinctual,and a fundamental part of everyday life—something most of us enjoy naturally.There are comedy channels on TV,comedy festivals and our favorite funny friend who's sure to get our giggle on.

So why do we need laughter experts?Surely they're for people who can't laugh for whatever reason.However,while the ability to laugh is innate,the decision to activate and use it to its full ability is a choice.

When life gets stressful;illness creeps in;relationships are put to the test or we're struggling financially,there's rarely much to laugh about.So,we don't.Yet turning into the lighter,more humorous side of life,and activating one's "laughter self" is critical to mental health.Rather than waiting for something funny to happen or for life to be a bed of roses,we can transform our emotional state by tapping into our laughter and humor resources.This helps create distance between us and our pain and improve our moods and resilience(恢复力) to stress.It provides relief and release from some of the stress that has embedded in our bodies and minds,freeing ourselves to power forward,even a little.

Ironically,because laughter is an innate and largely unconscious behavior,it's rarely given much thought.As it's seldom thought about,it can't be that important.

Wrong.If laughing is a more complex behavior,my belief is people will pay greater honor to it,rather than something to laugh off.It's actually one of the most complicated things our bodies process.It is a vocal means of communication before language forms and the brain has fully developed.The vast majority of us maintain the ability to laugh until our final curtain falls,even amid declining cognitive function.

Turning toward the healing power of humor and laughter assists with personal and professional resilience,performance and overall well-being.No joke.

A significant proportion of the American populace within the working-age demographic are encountering challenges in meeting the financial demands associated with health care, as per a recent comprehensive evaluation. This study, which is the inaugural edition of the Health Care Affordability Survey conducted by the Commonwealth Fund, reveals that a substantial 51 percent of adults falling within the age bracket of 19 to 64 years have expressed that affording health care for themselves and their family is either exceedingly challenging or moderately difficult. This observation encompasses 43 percent of individuals who are beneficiaries of health insurance provided by their employers and an even higher 57 percent who have secured health insurance through a marketplace or have opted for an individual plan.

Additionally, it is noteworthy that nearly one-half of the working-age adults who are under the Medicare program and 45 percent of those who are recipients of Medicaid also admit to facing hardships in covering their health care expenses. It is particularly striking that a majority, specifically 65 percent, of working-age adults have indicated that the escalation in the cost of various goods and services over the past year has had a detrimental impact on their capacity or that of their family to manage health care expenses.

The aforementioned survey, which is based on a sample that is representative of the nation and comprises nearly 7,900 individuals who are 19 years of age or older, was carried out from the mid-point of April through the month of July in the current year. This survey follows on the heels of another analysis conducted by the research entity known as KFF, which demonstrated an upward trend in the costs associated with health insurance for employer-sponsored plans as well as an increase in the contributions made by workers towards these plans in the year 2023.

The newly disseminated analysis has further unearthed that 38 percent of the individuals who participated in the survey identified cost as the primary factor that led them or a family member to either forgo or postpone the receipt of necessary health care services or the procurement of prescribed medication within the last 12 months. This includes 29 percent of those who are under the protection of employer-based coverage, 37 percent who are insured through individual and marketplace health plans, 42 percent who are covered by Medicare, and 39 percent who are recipients of Medicaid.

Furthermore, it is observed that more than six-tenths of the individuals who are devoid of any form of health insurance have reported that they or a family member have had to delay or forgo medical care due to financial constraints. Among all those who have reported such instances of skipping or delaying care, a considerable 57 percent have stated that a health issue has consequently deteriorated.

Donna Strickland was awarded the 2018 Nobel Prize in Physics jointly with Arthur Ashkin and Gérard Mourou.It's the first time in 55 years that a woman has won this famous prize, but why has it taken so long? We look at five other pioneering female physicists — past and present — who actually deserve the prize.

Jocelyn Bell Burnell

Perhaps the most famous snub (冷落): the student Bell discovered the first radio pulsars in 1967, when she was a PhD student at Cambridge.The Nobel Prize that recognised this landmark discovery in 1974, however, went to her male supervisor, Antony Hewish.Recently awarded a £2.3 million Breakthrough Prize, which she gave away to help under-represented students, she joked to The Guardian, "I feel I've done very well out of not getting a Nobel Prize."

Lene Hau

Hau is best-known for leading the research team at Harvard University in 1999 that managed to slow a beam of light, before managing to stop it completely in 2001.Often topping Nobel Prize prediction lists, could 2019 be Hau's year.

Vera Rubin

Rubin discovered dark matter in the 1980s, opening up a new field of astronomy.She died in 2016, without recognition from the committee.

Chien-Shiung Wu

Wu's "Wu experiment" helped disprove the "law of conservation of parity".Her experimental work was helpful but never honoured, and instead, her male colleagues won the 1957 Nobel Prize for their theoretical work behind the study.

Lise Meitner

Meitner led groundbreaking work on the discovery of nuclear fission.However, the discovery was acknowledged by the 1944 Nobel Prize in Chemistry, which was won by her male co-lead, Otto Hahn.
