3 . “Please, no flash photography.”

Polite requests like this can be found in museums all over the world, but they generally fail to persuade people out of taking photos of whatever they feel like. The same goes for concerts, movie theaters and other places where people routinely ignore filming restrictions. A new patent from Apple may help discourage that rebellious behavior-on phones at least.

The patent, awarded to Apple today, outlines a system which would allow venues to use an infrared emitter (红外线发射器) to remotely disable the camera function on smartphones. According to the patent, infrared rays could be picked up by the camera, and interpreted by the smartphone as a command to block the user from taking any photos or videos of whatever they’re seeing.

Many musicians and performers have banned cellphones from their shows, either because they want their audiences to actually pay attention to them, or because they don’t want the free footage (片段镜头) going viral around the web. Despite this, unauthorized (未授权的) images still manage to make their way into the public eye. The last concert of American singer Prince before he passed away was supposed to be cellphone-free —it apparently wasn’t. If Apple’s patent is introduced into iPhone software, and venues put infrared emitters around their stage, leaks like this could potentially stop happening.

But the patent also raises questions about the sort of power that this technology would be handing over to people with more immoral intentions.

Right now, there’s no guarantee that Apple intends to put this technology into any of its software —Apple doesn’t act on many of the thousands of patents it files each year —and the company wasn’t immediately available to comment on its plans for the patent.

Given the company’s rigid support of personal privacy when it comes to police requests to break into users’ devices, it’s possible that Apple just patented the technology so that no one else will use it. But who knows, if it does intend to introduce this feature to future operating systems, sales of alternative shooting devices like camcorders, or even GoPros, could get a much-needed boost, as people try to avoid having to use the prohibitive software.

7 . As an immigrant from China, my mother loves Chinese culture deeply. She _________ Chinese food every night. She prefers to do it herself at home because she thinks the local restaurants aren’t authentic. _________, strangely enough, she likes to take my son to Panda Express to have _________ with her friends who are also from China. She is even _________ to point it out whenever they are at a food court.

Why is American Chinese food not _________ among some Chinese Americans? How is American Chinese food not better than _________ Chinese food? I can’t _________ that it’s not as good as authentic Chinese food. In fact, authentic Chinese food really tastes better while American Chinese food _________ to have food with its own taste — they are right for different persons. It’s important to _________ American Chinese food from authentic Chinese food. They are not the same __________ and have their own characteristics. So they should be treated __________. That’s why my mother thinks that Panda Express is not very authentic, but can still __________ it. Actually, American Chinese food is often created by Chinese immigrants according to their own preferences. As people from various countries have differences in their __________, it is changing.

My mother has a deep feeling for authentic Chinese food and restaurants, so I decide to open a restaurant where she and other immigrants can feel the __________ of Chinese family dinner. My son says he’ll learn Chinese cooking skills from me, which, I think, should be __________ from age to age. Likewise, I’ll also pass on the Chinese food culture to the world.

8 . Plastic, which is now common, contains endocrine-disrupting chemicals, or EDCs (内分泌干扰物), that has been linked to increased risk of many chronic diseases. Parental exposure to EDCs, for example, has been shown to cause metabolic (新陈代谢的) disorders, including obesity and diabetes, in the later generations.

Led by Changcheng Zhou, a professor of biomedical sciences in the School of Medicine at the University of California, the researchers investigated the impact of fathers’ exposure to a phthalate called dicyclohexyl phthalate, or DCHP (邻苯二甲酸二环己酯), on the metabolic health of first generation (F1) and second generation (F2) in mice. Phthalates are chemicals used to make plastic more durable.

The researchers found that fathers’ DCHP exposure for four weeks led to high insulin (胰岛素) resistance and impaired insulin signaling in F1. The same effect, but weaker, was seen in F2 .

“We found fathers’ exposure to EDCs may have intergenerational and transgenerational detrimental effects on the metabolic health of their later generations, ”Zhou said. “To the best of our knowledge, our study is the first to demonstrate this.”

In the case of fathers’ exposure in the study, intergenerational effects are changes that occur due to direct exposure to a stressor, such as exposure to DCHP of fathers (F0 generation) and his F1 generation. Transgenerational effects are changes passed down to later generations that are not directly exposed to the stressor (for example, F2 generation).

“This suggests that fathers’ DCHP exposure can lead to sex-specific transgenerational effects on the metabolic health of their later generations,” Zhou said.

Zhou stressed that the impact of exposure to DCHP on human health is not well understood, even though DCHP is widely used in a variety of plastic products and has been detected in food, water, and indoor particulate matter.

“It’s best to minimize our use of plastic products,” Zhou said. “This can also help reduce plastic pollution, one of our most pressing environmental issues.”

9 . Face blindness, a mystifying condition that can trick us into believing we recognize people we’ve never met or make us fail to recognize those we have, has been previously estimated to affect between 2 and 2.5 percent of people in the world.Now, a new study by researchers at Harvard Medical School (HMS) and the VA Boston Healthcare System is providing fresh insights into the disorder, suggesting it may be more common than currently believed.

Published in February 2023 in Cortex, the study findings indicate that as many as one in 33 people may meet the criteria for face blindness, or prosopagnosia (面孔失认症).“This translates to more than 10 million Americans,” the research team said.

The study found similar face-matching performance between people diagnosed with prosopagnosia using stricter vs looser criteria, suggesting that diagnostic criteria should be expanded to be more inclusive. That could lead to new diagnoses among millions who may have the disorder but don’t realize it.

The study results are based on a web-based questionnaire and tests administered to 3,341 individuals.First, the researchers asked participants whether they experience difficulties recognizing faces in their everyday lives.Then they administered two objective tests to determine whether they had difficulties learning new faces or recognizing highly familiar famous faces.

The results showed that 31 individuals out of the 3,341 had major prosopagnosia, while 72 of the 3,341 had a milder form. The researchers also observed that there were no neatly divided separate groups of people with poor or good ability to recognize faces. Rather, the ability to recognize faces appeared to lie on a continuum (连续体).

Finally, the researchers compared face-matching scores among people with prosopagnosia diagnosed using different criteria and found that using stricter diagnostic cutoffs did not correspond with lower face-matching scores.

In the new study, the researchers provide diagnostic suggestions for identifying mild and major forms of prosopagnosia based on guidelines for major and mild neurocognitive disorders in the DSM5, the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders.
