Apple revealed new ways to discover and organize apps, confirmed a significant change and announced a new feature that will let users unlock their cars with their smartphones.

The updates, announced at Apple (AAPL)’s annual Worldwide Developers Conference on Monday, highlight the company’s continued effort to involve itself into seemingly every corner of our lives, from our cars and living rooms to our personal health, while also facing the potential for app tiredness more than a decade after the App Store launched.

The company kicked off the event by focusing on iOS 14, the upcoming operating system for the iPhone. As part of its presentation, Apple unveiled a new feature called App Library, which automatically organizes the apps on your homescreen so you don’t have to scroll (滚屏) through several pages.

Apple also developed a more perfect way to discover and access new apps. The feature, called App Clips, offers a small part of an app for use at the moment it’s needed, whether it’s for ordering a scooter on demand or food from a restaurant. These apps are small in size and connect with Apple Pay. Users can then decide to download the full version of the app from the App Store.

At the same time, Apple attempted to demonstrate the still undeveloped potential of the iPhone, which remains its chief moneymaker. Having already turned the iPhone into a digital credit card, Apple now has plans to make it a digital car key. A new feature, called Carkey, will initially be available with the new 2021 BMW 5 series.

A new high tech mirror，designed specifically for cancer patients，will only become reflective when a user smiles into it.The plug-in device，which exactly looks like a tablet，comes equipped with a mirror，a built-in camera，and a smart material triggered(触发)by some software.Facial recognition technology captures the face and instructs the surface of the mirror to change when a smile is detected.It can hang on a wall or sit on a table，much like a conventional mirror.Unlike a regular mirror，however，the price is currently standing at a surprising $2000—$3000.

After witnessing a close family member struggle through cancer treatments，Turkish industrial designer Berk Ilhan decided to focus his work primarily on products that would cultivate joy and benefit cancer patients directly.

“She told me in the first days after her diagnosis，it was difficult for her to look in the mirror and acknowledge she had cancer.”he said.“Our facial expressions affect how we feel.If we flex(绷紧)our facial muscles to smile，our brains think that something good happened and as a result，we feel happiness.”

After earning his master’s degree at the School of Visual Arts in New York，Ilhan spent several weeks visiting cancer hospitals in Turkey，speaking to both patients and doctors.He spent two years designing and developing the mirror.The idea behind it is that smiling，even when forced，can make us feel better，according to research known as the facial feedback hypothesis.Laughter is linked to improved immune system function，and some researchers claim it can even increase our lifespans.

Ilhan is currently producing the mirror in limited quantities at the previously mentioned price.The product，however，will soon be launching a campaign in which Ilhan hopes to raise enough funds to bring the price down to $500.He also intends to donate the mirror to hospitals when it is financially possible to do so.

In a study published in the U. S. journal Science, researchers from the Chinese Academy of Agricultural Sciences(CAAS) and the University of Florida identified the chemical combinations and genetic recipe for better tomato flavor(味道).

“In recent years, consumers often complain that the modern tomato is less flavorful than it once was” said co-principal researcher Sanwen Huang. “Our results provide a practical road map for breeding tomato varieties with better flavor.”

For the study, a 170-person consumer group was created to evaluate 160 tomatoes representing 101 varieties, based on qualities such as “overall liking” and “flavor degree”. The results pointed to dozens of chemical compounds of interest, and further research using a statistical model discovered 33 flavor compounds connected with consumer liking, such as glucose(葡萄糖). The reason why modern tomatoes don’t taste good anymore is that a total of 13 of these flavor-associated compounds “were significantly reduced in modern varieties,” their paper wrote. Moreover, the researchers found that smaller fruit tended to have greater sugar content, suggesting that “selection for more sizable tomatoes has cost sweetness and flavor”.

Based on this knowledge, Huang and Professor Harry Klee of the University of Florida studied the whole genomes of 398 varieties of tomato, identifying about 250 positions of genes on a chromosome(染色体), which controlled tomato flavor.

“We’re just fixing what has been damaged over the last half century to push them back to where they were a century ago,” said Klee in a statement. “We can make the supermarket tomato taste noticeably better.” Klee said new tomato varieties with better flavor could be ready in three to four years. In addition, “the genes and pathways identified here in the tomato almost certainly point to pathways worth researching for improvement of flavor quality in other fruit crops,” they wrote.
