1 . Peru is prepared to approve new laws that would make it easier to investigate and punish researchers who engage in academic cheating, including paying to have their names added to a paper.

The move comes as Peru’s national science agency seeks to crack down on authorship buying and other dishonest practices. It recently removed two scientists accused of dishonest publications from a national registry that is key to receiving government sponsor, job promotions, and salary bonuses. And officials are investigating more than 170 other researchers at a Peruvian media report claimed were involved in academic misconduct, including 72 listed in the national registry who work at 14 universities in Peru.

The new laws will empower universities and government officials to punish such behavior. Dishonest publishing practices “ transcend mere moral misbehavior” because they enable researchers to obtain government and private funding without telling the truth, says Edward Málaga Trillo, a member of Congress who is the driving force, behind the bills, which lawmakers are expected to finalize early this year. “These individuals are operating academic cheating.” Peru’s academic community has been struggling with a rising tide of false authorship and related problems. One cause, some researchers say, is a 2014 law that aimed to stimulate research by rewarding researchers who boost their publishing output. For example, under a scoring system used by universities,researchers can earn five points for authorship in a high-impact journal, and two points when the journal is lower impact. A massing points can bring bonus payments and career promotion.

Signs of dishonest publishing can be obvious, notes Nahuel onteblanco,president of Cientificospe, a Peruvian group that investigates misconduct. Many of the papers cited by Punto Final have numerous co-authors from different nations with few prior publications on the same subject. “If your colleague consistently publishes 20 articles a year with co-authors from other countries, that’s highly suspect.” Monteblanco says.

3 . It was a busy morning and I had several things to do before the day became too hot to be outside the house. As I was walking by the side of a busy road, I saw an old lady, maybe in her 80s, standing dangerously close to the traffic. Although my mind was preoccupied, I thought to myself that I should warn her not to stand so close to the busy traffic rushing by. When I reached the spot where the old lady was standing, I noticed that she was trying to get attention of passers-by who of course were too busy to take note of her.

She kept pointing to the middle of the road. When I tried to gently move her back further away from the edge of the busy road, she said that she was standing there because she dropped her house key in the middle of the road and was unable to enter her house without the key. I looked around and no one seemed to be interested in the two of us. I knew I was getting delayed but decided to help.

The traffic was busy on the road with people on two-wheelers or in cars as well as school buses rushing with school children. It was the worst time of the day to cross a busy road without a traffic light. I asked the old lady to stay at a safe distance, took a deep breath, and carefully stepped onto the road waving my hands crazily, fearing to be hit by an oncoming vehicle. At first one lane (车道) stopped and then I moved further on to the middle of the road continuing to wave my hands.

I quickly picked up the key and ran back to the old lady waiting by the side of the road and returned the key to her. As I turned to continue my hurried walk, the old lady pulled me by my hand and gave me a big warm hug. I felt so happy to have helped this old lady.

5 . Want to explore new cultures, meet new people and engage in meaningful pursuits? You can do all the three with Global Development Association (GDA). No matter what life stage you’re at, wherever you go, and whatever project you undertake with us, you’ll create positive changes in a poor and remote community.

We welcome volunteers from all walks of life and backgrounds. While the majority of our volunteers are between the ages of 17 and 24, we’re currently in need of volunteer managers aged 25 to 75, who play a very important role in the safe and effective operation of our programs. Our positions include project managers, mountain leaders, and communication officers.

Your chosen role could vary from enhancing a community’s access to clean drinking water to preserving valuable local cultures. Or perhaps you might design adventure challenges to train our young volunteers.

Not only will you be aiding the personal growth of our young volunteers, but you’ll also be picking up new skills and expanding your cultural insights. You’ll likely meet individuals who could become lifelong friends.

This summer we have both 4-week and 7-week programmes:

GDA ensures that volunteers work with community members and local project partners where our help is needed. All our projects aim to promote the development of poor and remote communities.

There is no other chance like a GDA programme. Join us as a volunteer manager to develop your own skills while bringing benefits to the communities.

6 . All the hard work that you’ve spent making strong passwords, combining pet names with numbers, symbols and birthdates could all soon be for nothing as a new artificial intelligence (AI) model achieves a 95% accuracy of understanding keystrokes (按键).

At least that’s the extreme view of a team of British researchers. Using a deep learning model, they were able to steal data from a laptop’s keyboard using a microphone to understand what is being typed. This, in theory, would allow hackers who were able to gain access to your laptop to obtain what is being typed including messages and passwords.

The first step for this attack to work is by recording the keystrokes on someone’s keyboard. This is needed to train the algorithm (计算程序). While this could be done from the laptop’s microphone, it could equally be achieved by placing a smartphone near the computer. By pressing 36 keys on a modern MacBook Pro 25 times each and recording the sounds produced, the researchers gained a full set of training data. This information is turned into waveforms to show identifiable differences between each key. With this information in hand, they could then build a machine-learning model to understand which of these waveforms lines up with which key.

“If you get enough data, a model can be built pretty easily,” Oli Buckley, a professor of Internet security. “If it works on one keyboard, it will likely work on the next. The MacBook has a nice, quiet keyboard, so the idea is that if it works on something quiet, it will have a wide-reaching ability on louder keyboards”.

While this all sounds pretty scary, not to mention a new form of hacking (侵入) to look out for, it isn’t quite as worrying as it sounds.

“A good sample of data is needed for it to work, so this changes if you’re using a Dell, a MacBook or an external keyboard. Also, factors change. Some people type louder and harder, or my keyboards full of cat hair so that impacts things slightly”, says Buckley.

7 . Five years ago, French navy officer Jérôme Chardon was listening to a radio program about the journey of the bar-tailed godwit, a bird that migrates 14,000 kilometers between New Zealand and Alaska. Chardon understood how treacherous the journey would be, as heavy storms frequently hit Pacific island communities. Yet, somehow, bar-tailed godwits routinely pass through the area uninjured. Chardon wondered whether learning how birds traveled could help coastal communities avoid natural disasters.

This past January, a team from France’s National Museum of Natural History (NMNH) began experiments designed to test Chardon’s idea. Researchers with a project led by Frédéric Jiguet from NMNH equipped 56 birds of five species with cutting-edge animal tracking technology. The team members were ferried to remote islands in French Polynesia, where they attached tags (标签) using tracking technology. These tags sent the birds’ locations to the International Space Station, which bounced the data back to scientists on Earth who could then follow the birds — waiting to see how the birds responded to natural disasters.

The project is focusing on birds’ ability to hear infrasound, the low-frequency sound humans cannot hear but that the researchers believe is the most likely signal birds would use to sense storms and tsunamis (海啸). In a 2014 study, scientists tracking a kind of golden-winged birds in the central and southeastern America found that the birds flew up to 1,500 kilometers to escape from an outbreak of tornadoes (龙卷风) that killed 35 people. The birds fled at least 24 hours before any extreme weather hit, leaving the scientists to believe that they had heard the storm system from more than 400 kilometers away.

The team plans on tagging hundreds more birds across the Pacific to prepare for a potential tsunami. “I think if there’s one wave that spreads across islands, we can get data from different species at different locations,” says Jiguet. “That will say it’s worth continuing to tag and to develop local systems to better analyze this. There are chances that we will develop a bird-based tsunami early warning system.”

8 . Do you think cookies can tell stories? Jasmine Cho, 35, does.

A baker, artist, entrepreneur and activist, Cho tries to spread knowledge about social justice issues and diversity through the delicious medium of cookies.

It was in high school that she discovered her love of baking. At a sleepover a friend taught her how to make a dessert, “sort of demystifying baking and that whole process”.

Later, Cho realized her second passion: learning more about her Asian, American culture. An elective in college that taught Asian-American immigrant experiences brought an emotional moment for her. “So many emotions came up that I just couldn’t articulate. It was like this mix of anger, of relief, empowerment, sadness…” Cho said.

Cho realized she could combine these two passions to educate others about influential Asian American people and showcase matters that were important to her. With her online bakery, she designed cookie portraits about people she admired and posted the images on Instagram. “I don’t think I ever really knew how to communicate these stories until I found cookies,” Cho said. “Cookies are just so disarming. Who doesn’t like cookies?”

One cookie that Cho has identified with deeply is one she made of George Helm, a Hawaiian activist in the 1970s.

“It’s insane the amount of injustice that the native Hawaiian population has faced as well through the whole annexation (吞并) of the kingdom. There were so many horrific stories that I heard about nuclear testing and the fallout (核爆炸后的沉降物) impacting native Hawaiian populations in all of this,” Cho said, “George Helm was one of those activists who really represented the spirituality of the native Hawaiians and the connection to their land, to nature.”

Among her amazing cookie art are other political figures such as Larry Itliong, a Filipino-American labor organizer, and pop culture figures such as Keanu Reeves, a Canadian actor.

Cho hopes her cookie art continues to inspire people to be creative and think positively.

“Instead of trying to think of something new and original, just look inward and see, maybe there’s already a passion or a love that you have,” Cho said. “Use that for something that will serve the world in a better way.”

9 . What do a student in China, an office worker in the UK and an astronaut in space all have in common? They all eat instant noodles. And they’re not alone—over 100 billion servings of instant noodles are consumed globally each year, making them one of the world’s most successful industrial foods. But how did this happen?

Put simply, they’re cheap to produce and cheap to buy, which was exactly what their creator intended to achieve. Momofuku Ando, an entrepreneur, spent a year perfecting the recipe just after the Second World War. He wanted to make something similar to traditional noodles. His creation was instantly popular, playing a part in the post war economic rise. Even in the year 2000—according to a poll by the Fuji Research. Institute—instant noodles Were voted the most successful invention, ahead of high speed trains, laptops and karaoke.

According to the World’s Instant Noodles Association, China, Indonesia, Vietnam and India—in that order—all consumed more instant noodles than before in 2021. Instant noodles’ popularity abroad is in part due to how easy they are to adapt to local tastes. In Thailand, for example, you can get green curry flavour, while in Mexico the noodles are garnished (加饰菜) with lime and salsa. And it seems that consumers have grown to expect innovation. Nisin, the food company founded by Ando launches over 300 products yearly, according to employee Kasura Suzuki.

Instant noodles have their critics, too. Their rise in popularity has come at an environmental cost—they’re made with palm oil, contributing to deforestation, and their packaging is plastic. And while they are a hot, tasty and filling meal, instant noodles don’t have much nutritional value, and include high levels of salt and fat. Nevertheless, instant noodles are undoubtedly lifesavers in emergency or extreme situations.

More than 60 years after their invention, instant noodles have become the default food for anyone short on money, time, or even a kitchen.
