A plant believed to have vanished decades ago has been rediscovered in remote northern Australia, thanks to a chance observation uploaded to the citizen science platform iNaturalist. Scientists say the remarkable find highlights how everyday people are becoming increasingly important to modern biodiversity research and conservation. The discovery began when…
One of the biggest mysteries in human evolution has long puzzled scientists: Why are humans so overwhelmingly right-handed? Around 90% of people across cultures prefer using their right hand, a level of dominance not seen in any other primate species. Researchers have spent decades studying the brain, genetics, and development…
Scientists have developed a surprising new way to power materials that normally cannot conduct electricity, opening the door to a new generation of ultra pure near infrared LEDs for medical imaging, communications technology, and advanced sensors. The breakthrough relies on tiny “molecular antennas” that funnel electrical energy into insulating nanoparticles.…
Renewable energy sources can cut harmful emissions, reduce reliance on fossil fuels, and improve efficiency. However, many clean energy technologies remain expensive because they depend on costly materials such as platinum group metals (PGM) and require efficient ways to store energy for later use. Researchers at Washington University in St.…
The explosive growth of electric vehicles has intensified the search for ways to make electric motors more energy efficient. One major challenge is iron loss, also called magnetic hysteresis loss, which occurs when magnetic fields inside the motor repeatedly reverse direction. This process wastes energy as heat within the motor…
Correlated and entangled photon pairs are essential tools in quantum optics. Scientists usually create these photon pairs through a process called spontaneous parametric down-conversion (SPDC), in which a powerful, highly stable laser shines into a nonlinear crystal. Because SPDC depends so heavily on coherent laser light, researchers have long considered…
Coffee has been part of human culture for more than 600 years, and today it remains one of the world’s most popular drinks. People now consume nearly two kilograms of coffee per person each year on average, often with strong opinions about brewing methods, beans, and blends. Genetics can also…
A new study from Adelaide University suggests that the ancient Tethys Ocean played a major role in shaping Central Asia’s landscape during the Cretaceous period, long before the rise of the Himalayas. The research team reached this conclusion through a large-scale data analysis that combined hundreds of thermal history models…
Watermelon has long been a summer favorite, but research suggests this refreshing fruit may offer benefits far beyond hydration. Studies published in Nutrients found that people who regularly eat watermelon tend to have healthier overall diets and may also support better heart and blood vessel function. Researchers say watermelon provides…
Going without food for several days does far more than force the body to burn fat. Research published in Nature Metabolism revealed that extended fasting sets off widespread biological changes throughout the body, including shifts linked to the brain, metabolism, and immune system. Scientists found that many of the most…
An international team of researchers has reported a striking Alzheimer’s breakthrough in mice using specially engineered nanoparticles that do much more than deliver medicine. These microscopic particles act as drugs themselves, helping the brain restore its own natural cleaning system and dramatically reducing toxic protein buildup linked to Alzheimer’s disease.…
Paleontologists from the Fundación Conjunto Paleontológico de Teruel-Dinópolis have published new findings in the scientific journal Vertebrate Zoology describing an extraordinary stegosaur skull discovered in Riodeva (Teruel, Spain). The fossil, which comes from a plated dinosaur that lived about 150 million years ago, is also helping researchers propose a new…
Researchers from Trinity College Dublin have uncovered an early 9th century manuscript in Rome containing one of the oldest surviving versions of the earliest known poem written in English. The manuscript, now housed in the National Central Library of Rome, includes Caedmon’s Hymn, a short Old English poem believed to…
Repeated weight loss followed by weight regain, often called “yo-yo dieting” or weight cycling, has long been viewed as unhealthy and potentially even worse than staying overweight. However, a major new review published in The Lancet Diabetes & Endocrinology argues that this belief is not backed by strong scientific evidence.…
Scientists have discovered that a powerful cancer-linked protein does more than fuel tumor growth. It also helps cancer cells survive by repairing damaged DNA, a finding that could eventually improve treatments for some of the deadliest cancers. The study, published in Genes & Development, focused on MYC, a protein that…
Climate change is steadily stripping oxygen from rivers around the world, according to a new study published May 15 in Science Advances. Researchers found that this long-term oxygen decline is happening across most river systems, with tropical rivers emerging as the most vulnerable. The findings point to an urgent need…
Exercise is widely known for building stronger muscles, but new research suggests it also reshapes the brain in ways that improve endurance. A study published in the Cell Press journal Neuron found that repeated exercise changes brain activity linked to the body’s ability to run farther and faster over time.…
Mitochondria are often described as the power plants of the cell, but in the brain, their role may be even more important than scientists once realized. These tiny structures supply the energy that neurons need to communicate, form memories, and keep the brain working smoothly. In a study published in…
Scientists have produced the clearest view ever of part of the cosmic web, the enormous hidden network of matter that stretches across the Universe and connects galaxies together. After spending hundreds of hours collecting observations, an international team captured a detailed image of a massive cosmic filament linking two actively…
People with anxiety disorders may share a measurable change in brain chemistry involving choline, an essential nutrient tied to memory, mood, cell structure, and nerve signaling. Research from UC Davis Health found that people diagnosed with anxiety disorders had lower levels of choline in the brain than people without anxiety.…
Fossils from Ethiopia are reshaping one of the biggest stories in human history. Instead of a neat march from ape like ancestors to modern humans, evidence from the Ledi Geraru field site points to a much messier and more fascinating reality: several human relatives may have shared the same African…
Deep beneath the eastern Pacific Ocean, roughly 1,000 miles west of Ecuador, a seafloor fault has been producing magnitude 6 earthquakes with striking regularity for at least 30 years. The quakes occur about every five to six years, repeatedly rupturing nearly the same sections of the fault and reaching nearly…
Researchers at the Marshall University Joan C. Edwards School of Medicine have uncovered new evidence that tiny particles created in the gut may contribute to inflammation and chronic diseases linked to aging. The findings provide fresh insight into the connection between gut health, metabolism, immune function, and even sleep-related biological…
For years, I noticed the same trend while working as a public health dentist and researcher. Patients with serious infections deep inside their teeth often seemed to struggle with broader health issues, especially diabetes. At the time, the connection was unclear. Now, growing scientific evidence is beginning to explain it.…
As summer approaches, many people try to get back into healthier exercise habits. Most of us already know physical activity is important, but sticking with a routine can still feel challenging, especially when time is limited. Current health recommendations suggest exercising for at least 2.5 hours each week, with 5…
Researchers have identified a gigantic new species of long necked dinosaur in Thailand that is now considered the largest dinosaur ever discovered in Southeast Asia. The finding comes from a collaboration led by scientists from University College London (UCL), Mahasarakham University, Suranaree University of Technology, and Thailand’s Sirindhorn Museum. The…
As cannabis use grows among older Americans, Stanford Medicine experts are warning that today’s marijuana products are far more powerful than many people realize, and they may come with significant health risks. Eloise Theisen never expected to become a specialist in medical cannabis. Now a geriatric nurse practitioner focused on…
Vitamin B2 is essential for human health, but new research suggests it may also help cancer cells stay alive. Also known as riboflavin, vitamin B2 cannot be produced by the body and must come from food sources such as dairy products, eggs, meat, and green vegetables. Once absorbed, the vitamin…
Scientists have uncovered new evidence that serotonin, a brain chemical best known for helping regulate mood, may also worsen tinnitus, the persistent ringing or buzzing sound that affects millions of people worldwide. The research was published in the Proceedings of the National Academy of Sciences. Tinnitus can range from mildly…
More than 20,000 patients from three major National Institutes of Health (NIH) studies were included in a new analysis showing that elevated Lipoprotein(a) [Lp(a)] is tied to ongoing cardiovascular risk, even in people receiving standard treatment. The findings suggest patients with high Lp(a) levels may need more aggressive management of…
