Your type of humor might say something about your risk of depression and anxiety

New research published in Europe’s Journal of Psychology has found connections between different types of humor and mental health. The study indicates that while benevolent humor, characterized by kind-hearted jokes and good-natured teasing, is linked to lower levels of depression, anxiety, and stress, darker forms of humor, such as cynicism and irony, are linked to aspects of emotional distress. Over the past 40 years, the academic community has increasingly recognized humor as a crucial element in coping strategies, helping individuals to distance themselves from their problems, and thereby ...

Teens don’t know everything − and those who acknowledge that fact are more eager to learn

If you, like me, grew up in the 1980s and 1990s, you may have come across the classic refrigerator magnet, “Teenagers, leave home now while you still know everything.”

Perhaps you know a teen, or maybe you were a teen, like this: pop-star energy, a little too confident in your opinions, a little too certain that no one could know what you know. Adolescence is the period of life when people transform from children into adults. To handle the transition successfully, people need to shed parental dependencies and become more autonomous and independent. So it makes sense that teens think – or at least act like – they know everything.

Disinformation is rampant on social media – a social psychologist explains the tactics use

Information warfare abounds, and everyone online has been drafted whether they know it or not.

Disinformation is deliberately generated misleading content disseminated for selfish or malicious purposes. Unlike misinformation, which may be shared unwittingly or with good intentions, disinformation aims to foment distrust, destabilize institutions, discredit good intentions, defame opponents and delegitimize sources of knowledge such as science and journalism.

Why tornado outbreaks happen in the East during winter and not in Tornado Alley: report

Another winter of storms breaking out across the southeastern United States is reviving the conversation about the "movement" of the so-called "Tornado Alley," which is what the central U.S. is sometimes called. There are also questions about how climate change is bringing more deadly outbreaks year-round. The evidence shows it isn't what you might think.

Over the weekend, Tennessee had a tornado outbreak that spun an EF-2 and EF3 tornado, which brought with them 111-135 mph winds and 136-165 mph winds respectively. Six people were killed, including three who were sheltering in a trailer. Those three included a mother and her 2-year-old son.

Emotional intelligence protects runners from negative self-talk, study suggests

A study of more than 1,000 runners found that these individuals use more negative self-talk after a race when they perceive a higher level of stress. Negative self-talk was less common in runners with better emotional intelligence. The study was published in Psychology of Sport & Exercise. Negative self-talk refers to the habit of engaging in internal dialogue that is critical, self-deprecating, or pessimistic, undermining one’s self-esteem and overall mental well-being. It involves repetitive thoughts or statements that focus on perceived shortcomings, failures, or inadequacies. This can resu...

Matcha tea might help improve perception of emotions and sleep quality in elderly adults

A new study has found that drinking matcha, a type of green tea, may improve perception of emotions and sleep quality in older adults with a decline of cognitive functions. The study, conducted by researchers from Japan and published in the journal Alzheimer’s & Dementia, is the first long-term clinical trial to test the effect of matcha on psychological functions. The causes of dementia are numerous, and studies have suggested that nutrition plays a key role. Matcha is a popular beverage particularly in Japan and contains ingredients such as theanine, which has been suggested to improve short...

Fossils show dismembered young dinosaurs in belly of T. rex cousin

By Will Dunham (Reuters) - The young Gorgosaurus knew what it liked for dinner. About 75 million years ago in what is now Canada's Alberta province, this fearsome T. rex cousin set about hunting turkey-sized yearlings of a feathered plant-eating dinosaur called Citipes. With such prey numerous, the Gorgosaurus could be picky about what it ate. It dismembered the helpless Citipes and swallowed its meaty legs whole, ignoring the rest of the carcass. Scientists said on Friday they have unearthed fossilized remains of a juvenile Gorgosaurus that was 5 to 7 years old and about 15 feet (4.5 meters) ...

Light shed on psychological impact of antisemitic conspiracy theories on Jewish people

New research published in the British Journal of Psychology shows that Jewish individuals who believe antisemitic conspiracy theories are prevalent in society experience increased feelings of threat and a tendency to avoid those outside their group. This study, one of the first of its kind, sheds light on the often-overlooked consequences of conspiracy theories on the groups they target. While a significant amount of research has been done on why people believe in conspiracy theories, there has been little focus on how these theories affect the groups they target. Conspiracy theories can be ha...

Golden mole that swims through sand is rediscovered in South Africa after 86 years

The De Winton’s golden mole was last seen in 1937 on the north-western coast of South Africa, and later declared officially lost. This iridescent blind mole with hearing superpowers evades contact with humans and “swims” through sand dunes, making it very difficult to locate. But in November 2023, a team of conservationists and geneticists from the Endangered Wildlife Trust, Stellenbosch University and the University of Pretoria found the mole after tracking its environmental DNA through the sand dunes. Molecular biologist Samantha Mynhardt was part of the team that found the mole. We asked her about it.

How did this mole species stay ‘lost’ for so long?

Golden moles are elusive little animals that spend nearly their entire lives underground. They are very seldom seen by humans. Some species will occasionally come to the surface to forage on insects, typically only at night. In most cases, the only sign of golden mole activity is a raised ridge on the surface of the ground, indicating a shallow tunnel underneath. For the sand-dwelling species, such as De Winton’s golden mole (Cryptochloris wintoni), even these ridges are hard to find, since the subsurface tunnels collapse in the soft sand.

Astronomers finally caught radio waves from 40 large galaxies in the nearby universe

Supermassive black holes reside in some of the biggest galaxies in the universe. They tend to be billions of times more massive that our Sun, and not even light itself can escape a black hole once it gets too close.

But it’s not all darkness. Supermassive black holes power some of the most luminous celestial objects in the universe – active galactic nuclei, which shine across the spectrum of light, including radio waves.
