When a dog makes adorable puppy eyes, it might seem obvious that the dog is begging for a treat. But it turns out humans may be barking up the wrong tree by misreading their pets’ cues.

To put human-dog interactions to the test, animal behavior researchers Holly Molinaro and Clive Wynne of Arizona State University conducted two experiments in which they asked people to interpret a series of dog videos. 

In the first experiment, Molinaro and Wynne recorded dogs in happy situations, like being offered a leash to go for a walk, and negative (less happy) situations, like being close to a loud vacuum cleaner. In each situation, the dogs showed body language that indicated whether they were excited or upset. They then asked people to describe the dogs’ emotions.

Then the researchers edited the videos to change the dogs’ reactions: the happy dogs were edited into a negative context (near the vacuum), and the upset dogs were edited into the happy context (seeing a leash). Viewers were asked to describe the dogs’ emotions in these contexts.

When shown the edited videos, people frequently misidentified the situation, ignoring the dog’s body language and behavior and instead focusing on the situation around the dog. They believed the (upset) dog was happy to see the leash, while the (happy) dog was upset to be around the vacuum cleaner.

On December 10, 2025, young Australians with accounts on TikTok and Snapchat will wake up and find their profiles gone. Australia has banned young people under age 16 from having social media accounts as part of its new social media usage policy. 

Australia’s government passed the Online Safety Amendment (Social Media Minimum Age) Bill about a year ago to protect Australian children and teens from the harmful effects of social media, such as cyberbullying and mental health struggles.

“We want our kids to have a childhood and parents to know we have their backs,” said Australian Prime Minister Anthony Albanese after the policy was passed.

The law says young people cannot use the platforms even with parental consent. The government expects all platforms to deactivate user accounts for those under the age of 16 when the law goes into effect on December 10. This includes popular platforms YouTube, Instagram, and Facebook, as well as TikTok and Snapchat.

The law is going into effect just as a new study confirms that preteens who use social media struggle with reading, vocabulary, and memory more than peers who do not use social media. The research shows that even low levels of social media use negatively impact brain development.

One of the most exciting scientific ceremonies in the world begins with an odd tradition—the audience pelts the ceremony stage with hundreds of soaring paper airplanes! This is no regular awards night. The Ig Nobel Prizes celebrate seemingly silly, yet very real, scientific research done around the world. This year’s award winners included a group of scientists who painted zebra stripes on cows and another who recorded lizards eating pizza.

The Annals of Improbable Research, a science magazine, awards the Ig Nobel Prize (also called the Igs) to scientific achievements “so surprising that they make people laugh, then think.” Each year, 10 prizes are awarded to achievements that seem unusual and imaginative.

Japanese scientist Tomoki Kojima and his colleagues won an Ig this year for their research experiment painting cows with black and white zebra stripes. The experiment showed that the zebra pattern reduced the number of biting flies landing on the cows. The results suggest farmers who don’t want to use pesticides could instead use this unusual method to deter flies.

“When I did this experiment, I hoped that I would win the Ig Nobel. It’s my dream,” Kojima said in an interview with the Associated Press.

Clarence “Taffy” Abel skated into hockey history multiple times in his life as an Olympian and professional ice hockey player in the early 1900s—but part of his legacy wasn’t fully recognized until after his death. That is because Abel had kept his Ojibwe identity a secret.

Abel was born in the hockey-loving town of Sault Ste. Marie, Michigan, a city on the U.S.-Canada border. This area is also home to many Indigenous communities, including the Chippewa nation (now called Ojibwe) that Abel’s mother belonged to.

Around the age of 24, Abel represented his country at the 1924 Winter Olympics in Chamonix, France, as a member of the U.S. Olympic hockey team. He carried the American flag during the opening ceremony parade, becoming the first Native American to be the flag bearer at the Olympics. The U.S. hockey team went on to win the silver medal.

What nobody knew at the time was that Abel was Ojibwe. Abel grew up at a time when Native Americans faced severe discrimination, so he and his family downplayed his heritage so that he could have more opportunities.

“Taffy would have never got into the 1924 Winter Olympics if he would have [come] right out and said, Hey, I’m Native American,” George Jones, Abel’s nephew, told NPR.

Abel went on to have a successful career in the U.S. National Hockey League. He played for the newly formed New York Rangers and helped them win the Stanley Cup, hockey’s championship trophy, in 1928. He repeated the feat in 1934, this time while playing for the Chicago Blackhawks.

Abel became more open about his heritage once he retired from professional hockey. He died in 1964 and was inducted into the U.S. Hockey Hall of Fame nearly a decade later. He was inducted into the American Indian Athletic Hall of Fame in 1989.

The U.S. Hockey Hall of Fame web page dedicated to Abel said: “He left an indelible imprint in pro and amateur circles as a player, coach and manager. Taffy Abel was a name beloved by hockey followers across the continent.”

What animal wraps up its food like a mummy and then kills it with toxic puke? The feather-legged lace weaver spider!

It may sound like a spooky riddle, but it’s completely true. This small spider species doesn’t use a venomous bite to kill its meal—it uses deadly barf instead. 

The feather-legged lace weaver is a flattish, brown spider that is about half the size of a pea and preys on insects. Though the spider is common across the Middle East, Europe, and Africa, its unusual predation behavior caught scientists’ attention only recently.

Researchers from Switzerland, Germany, and Belgium just published a study detailing the lace weaver’s throw-up-and-then-eat method for feasting. While the spider does have fangs, it cannot produce venom like other spider species do. Instead, it creates a toxin in its digestive system. So, when the spider catches a fly in its web, it wraps the meal in spider silk and then throws up all over it. The venom-like barf kills the insect. Now the spider is ready for lunch. 

Though the lace weaver’s food preparation style was first documented in a 1931 scientific paper, it wasn’t until now that researchers confirmed the spider evolved away from a venomous bite.

Since the lace weaver has fangs but no venom, scientists concluded that the species lost its ability to kill with a simple chomp but has kept its toxicity in its digestive juices. For the lace weaver, spider sense really is a gut feeling!

Celebrated primatologist Jane Goodall has died. She was 91. Best known for her groundbreaking discoveries about chimpanzee behavior, Goodall dedicated much of her career to causes like environmentalism and animal welfare.

Goodall’s interest in animals began at an early age. She first observed wild animals and took notes about them as a child in England. It wasn’t long before she decided on a career in animal behavior. In 1960, when Goodall was 26, she was hired by the anthropologist Louis Leakey to study wild chimpanzees in what is now the African nation of Tanzania. 

Goodall’s chimpanzee observations led to several discoveries. For example, she observed a chimpanzee named David Greybeard removing the leaves from a stick and then dipping the stick into a termite mound to capture the insects. This was the first time a scientist noted an animal using a tool. 

“The reason why this was so exciting was because, at that time, it was thought by Western science that only humans used and made tools,” Goodall once explained. Scientists have since observed several other animals using tools.

Goodall found that each chimpanzee had its own personality and that chimps have complex emotions. This observation surprised some scientists, but Goodall later said she wasn’t surprised because she had noticed complex emotions in her childhood dog, Rusty. 

“We all know that [dogs] can be happy, sad, fearful and that they’re highly intelligent,” she pointed out. Goodall’s discoveries led to a new understanding of chimpanzees and strengthened support for protecting their natural habitat. 

Goodall, who became world famous, was at the forefront of the animal welfare and conservation movements. She founded the Jane Goodall Institute in 1977 to help promote conservation and, until her death, traveled the globe to talk about the importance of protecting the natural world. 

Goodall’s tireless work for the planet and all living things made her a hero to people of all ages. After her death, tributes poured in from scientists, politicians, actors, and many more. 

“Jane Goodall was the first to prove that an investigating scientist and a great ape living in the wild could become true friends,” said British scientist and broadcaster David Attenborough. “In doing so, she came to transform our understanding of chimpanzees.”

“Goodall’s legacy is not only in science but in the global movement she helped spark to protect nature and give hope for a better world,” said Will McCallum, co-executive director of the environmental group Greenpeace.

Imagine taking an evening walk and passing trees glowing like rainbows along the sidewalk or having a blue, glow-in-the dark houseplant as a night light! This is the reality Shuting Liu envisions after creating glow-in-the-dark succulent plants that recharge in sunlight.

“Picture the world of [the movie] Avatar, where glowing plants light up an entire ecosystem,” said Liu, a scientist from South China Agricultural University. “We wanted to make that vision possible using materials we already work with in the lab. Imagine glowing trees replacing streetlights.”

Liu and her colleagues found a way to inject bioluminescent compounds directly into succulent plants, causing the leaves to glow. A succulent is a type of plant with thick, fleshy leaves such as an aloe or cactus. The compounds—called afterglow phosphor particles—absorb light energy from the Sun during the day and slowly release light over time, showing up particularly well in dark places or at night. The injected phosphor particles can come in greens, yellows, reds, and blues.

The research team began this project looking to make a sustainable alternative for dim outdoor lighting. They had tried injecting bioluminescent compounds into other types of plants, like bok choy, but it was the succulents that glowed best.

The researchers were able to create a wall of 56 glowing succulents. The light was bright enough to read texts and illuminate objects. The glowing effect does fade and is not permanent, so the researchers are continuing to study the possibilities for using these glowing plants as lighting options.

“I just find it incredible that an entirely human-made, micro-scale material can come together so seamlessly with the natural structure of a plant,” said Liu. “The way they integrate is almost magical. It creates a special kind of functionality.”

Most people use their legs for standing and walking and rely on their arms when they eat, carry things, and write. People even have a dominant arm they use more than the other. But do octopuses also use certain limbs to do certain tasks? A new study suggests the answer is yes, but not because they need to.

In the study, a group of scientists observed 25 videos of octopuses in the wild and recorded nearly 4,000 different arm actions to accomplish tasks like crawling, swimming, collecting shells and other building materials, building dens, and capturing prey. Each time the scientists saw an octopus doing something with its arms, they watched the action a total of eight times to record what, if anything, each arm was doing to help accomplish the task. 

The scientists found that an octopus can change the shape of its arm in four ways: by bending, twisting, shortening, and elongating it. They recorded 12 types of arm movements, such as reaching and grasping.

In February 2024, American teenager Tejasvi Manoj watched as her grandfather was almost scammed out of $2,000 in a cybercrime attempt. Pretending to be a relative, the fraudster had sent an urgent email requesting money to settle a debt. Fortunately, Manoj’s dad alerted her grandfather to the scam before any money was sent. That experience made Manoj realize that elderly citizens are particularly vulnerable to online scams.

So she decided to do something about it. 

Since that day, Manoj has devoted her free time to developing a website called Shield Seniors, a resource that helps people aged 60 and older learn how to spot online scams and analyze suspicious messages. Though she is still building this resource, her work has already been recognized for helping protect an overlooked population that is particularly vulnerable to cybercrimes. In 2025, the project earned Manoj the title of Time magazine’s Kid of the Year.

 Cybercrime is any illegal activity involving computers and the Internet. It can include identity theft and using fraudulent messages (emails, texts, and phone calls) to get people to send money or share bank account details. There are thousands of cybercrime victims each year, many of them senior citizens. In 2023, the U.S. Federal Bureau of Investigation estimated that scams targeting people over age 60 caused more than $3.4 billion in losses. 

“I found out this was a much bigger problem than I could have anticipated,” said Manoj in an interview with Time. “After seeing these kinds of statistics, I became really concerned for my grandfather and for so many older adults.”

A rider galloping on a horse while holding a sharp spear is an image you might associate with ancient battles. But modern-day equestrians like South Africa’s Makhosazana “Khosi” Dlomo are keeping age-old battlefield skills alive through the unique sport of tent pegging.

“It is a military discipline… Tent pegging has more of an adrenaline rush,” said Dlomo in a video interview with BBC Sport Africa. 

In tent pegging, a rider uses a spear or sword to pierce a target as their horse runs past it. The target may be a cardboard peg stuck in the ground or a series of rings hanging from a pole. Tent pegging requires excellent timing, accuracy, and coordination between the horse and rider as they charge toward the target.

“You’re hanging off the side of a horse and you need to trust that this horse is stable. And if you don’t trust the animal, then it’s not going to work out,” said Dlomo.
