Perceived loss of control may lead to an increase in conspiracy theories, study finds

Studies of North Macedonians immediately after their country was renamed and of U.S. residents affected by a series of tornadoes showed that people who felt a loss of control over important events tended to increase their beliefs in conspiracy theories. The study was published in Psihologija. Conspiracy theories are generally thought of as “implausible claims that significant events are being caused by malevolent clandestine groups.” Claims of these “theories” typically run counter to explanations of events provided by relevant authorities and scientists. Belief in conspiracy theories tends to...

Donald Trump’s tweets attacking the media, Congress, and the courts often backfired, study suggests

New research provides evidence that Donald Trump’s attacks on the media, Congress, and the courts often result in increased support for those institutions. The study, published in Political Research Quarterly, examined whether the former president’s rhetoric influenced democratic attitudes among U.S. citizens. For the most part, exposure to Trump’s tweets either had no impact or lead to the strengthening of democratic attitudes. “We were interested in understanding the effects of President Trump’s undemocratic rhetoric on citizens’ democratic attitudes,” said study author Miguel Carreras, an a...

Insects may feel pain, says growing evidence – here’s what this means for animal welfare laws

At least a trillion insects are killed annually for food and animal feed. Routine slaughter methods include extreme heat and cold, often preceded by starvation. By comparison, “only” around 79 billion mammals and bird livestock are slaughtered every year.

Scholars have long recognized that the survival value of pain means many animals experience it, supposedly with the exception of insects. But we surveyed more than 300 scientific studies and found evidence that at least some insects feel pain. Other insects, meanwhile, haven’t been studied in enough detail yet.

Understanding dishonesty in children – when, how and why do kids lie?

When asked if they peeked at a toy, 40% of children falsely confessed to peeking, even though they did not do so, in a recent study of lying in toddlers. When so many children made up falsehoods with no benefit, there is more to it than cheeky fibs.

The researchers, from Poland and Canada, tested children’s self-control at the age of 18 months by asking them not to peek at a toy. The same 252 children were tested again at age two and then again six months later. Only 35% of the young participants disobeyed the request not to look, but 27% of the peekers falsely claimed they had done as they were told.

Long-term consumption of food allergens may lead to behavior and mood changes

The prevalence of food allergies is increasing worldwide, approaching an epidemic level in some regions. In the U.S. alone, approximately 10% of children and adults suffer from food allergies, with allergies to cow’s milk, eggs, peanuts and tree nuts being the most common. Some patients have mild symptoms that might not need medical attention, leaving these cases unreported. Food allergies, or food hypersensitivities, result from the overreaction of the immune system to typically harmless proteins in food. They can manifest as a spectrum of symptoms, ranging from itching, redness and swelling ...

Why does the Alzheimer’s brain become insulin-resistant?

As the population ages, the number of people with neurodegenerative diseases, such as Alzheimer’s disease, increases. Approximately 75,000 Canadians are diagnosed with Alzheimer’s disease each year and experience a decline in their cognitive abilities. The ordeal usually lasts for several years while their family members watch helplessly.

Neurodegenerative diseases are characterized by proteinopathies — abnormal accumulations of proteins in the brain that impair the functioning of neurons. The most widely studied therapeutic approach to developing drugs for Alzheimer’s is to try to reduce the aggregation of amyloid-beta peptide and tau protein in neurons.

Why fusion ignition is being hailed as a major breakthrough in fusion – a nuclear physicist explains

American scientists have announced what they have called a major breakthrough in a long-elusive goal of creating energy from nuclear fusion.

The U.S. Department of Energy said on Dec. 13, 2022, that for the first time – and after several decades of trying – scientists have managed to get more energy out of the process than they had to put in.

Ada Lovelace’s skills with language, music and needlepoint contributed to her pioneering work in computing

Ada Lovelace, known as the first computer programmer, was born on Dec. 10, 1815, more than a century before digital electronic computers were developed.

Lovelace has been hailed as a model for girls in science, technology, engineering and math (STEM). A dozen biographies for young audiences were published for the 200th anniversary of her birth in 2015. And in 2018, The New York Times added hers as one of the first “missing obituaries” of women at the rise of the #MeToo movement.

Sound of a dust devil on Mars recorded for first time

The sound of a dust devil on Mars was recorded for the first time as the eye of the whirlwind swept over the top of NASA's Perseverance rover, a new study said Tuesday.

"We hit the jackpot" when the rover's microphone picked up the noise made by the dust devil overhead, the study's lead author Naomi Murdoch told AFP.

US researchers announce 'major scientific breakthrough' in nuclear fusion

US researchers announced a historic nuclear fusion breakthrough on Tuesday that could pave the way for alternative clean energy sources.

The Lawrence Livermore National Laboratory (LLNL) said an experiment it conducted this month "produced more energy from fusion than the laser energy used to drive it."

A new breakthrough in nuclear fusion technology could allow humans to spread throughout the universe

Is intelligent life a temporary phenomenon that is insignificant in the grand scheme of things, or might it play a role in shaping the large-scale evolution of the universe?

While it has often been assumed that humans will have no real impact on the cosmos at large, some of the greatest physicists of modern times have challenged that idea. Almost a half-century ago, Freeman Dyson — one of the most influential theoretical physicists of the 20th century — wrote: “It is impossible to calculate in detail the long-range future of the universe without including the effects of life and intelligence.” The father of the field of quantum computing, David Deutsch, has also argued that life may determine the large-scale development of the cosmos. Some other big names in physics and cosmology who have seriously entertained the idea are Paul Davies, Seth Lloyd, and Lee Smolin, just to name a few.

Nuclear fusion: harnessing the power of the stars

The US National Ignition Facility (NIF), the interior of which is seen here in July 2008, has reportedly achieved a fusion reaction that produces more energy than was put into it

Washington (AFP) - The US Department of Energy's nuclear fusion laboratory says there will be a "major scientific breakthrough" announced Tuesday, as media report that scientists have finally surpassed an important milestone for the technology: getting more energy out than was put in.

The announcement has the scientific community abuzz, as nuclear fusion is considered by some to be the energy of the future, particularly as it produces no greenhouse gases, leaves little waste and has no risk of nuclear accidents.
