In a 2024 interdisciplinary study published in the Journal of Travel Research, ECU researchers applied the theory of…
Alzheimer’s disease (AD) is a progressive brain disorder and a leading cause of dementia worldwide. Despite years of research, there is still no cure. New antibody-based treatments that target amyloid β (Aβ) have recently emerged, but their benefits have been modest. These therapies can also be expensive and may trigger…
Climate change is dramatically reshaping how Greenland’s ice sheet melts, according to a new study led by the University of Barcelona and published in Nature Communications. Researchers found that extreme melting events are now happening more often, covering larger areas, and producing significantly more meltwater than in the past. Since…
Scientists are developing a new way to tackle two major global problems at once: plastic pollution and the demand for clean energy. By using sunlight, they are finding ways to turn discarded plastic into useful fuels. A recent study led by Adelaide University PhD candidate Xiao Lu examines how solar-powered…
Materials known as relaxor ferroelectrics have played an important role for decades in technologies such as ultrasound imaging, microphones, and sonar. Their unusual performance comes from the way atoms are arranged inside them. However, that internal structure has been extremely difficult to measure directly, leaving scientists to rely on incomplete…
For more than 500 years, Leonardo da Vinci has been admired as a brilliant artist, inventor, and thinker whose talents seemed far ahead of his time. Now, an ambitious international effort known as the Leonardo DNA Project is bringing scientists closer than ever to uncovering the biological roots of his…
After NASA’s Artemis II mission ended with a successful splashdown, engineers began closely reviewing data from across the mission. Their goal is to evaluate how major systems performed, including the Orion spacecraft, the SLS (Space Launch System) rocket, and ground infrastructure at Kennedy Space Center in Florida. Early findings suggest…
On April 17, engineers at NASA’s Jet Propulsion Laboratory (JPL) in Southern California sent a command to turn off an instrument on Voyager 1 known as the Low-energy Charged Particles experiment, or LECP. The spacecraft, powered by a nuclear energy source, is gradually losing power, and shutting down this instrument…
Creatine is widely known as a go to supplement for athletes and gym enthusiasts, often linked to improved strength and performance. But beyond the fitness world, scientists have been taking a closer look at how this compound affects both the body and the brain. From helping cells produce energy to…
Blood tests that track how certain white blood cells age may help identify depression by focusing on emotional and cognitive symptoms rather than physical ones. The research, published in The Journals of Gerontology, Series A: Biological Sciences and Medical Sciences, moves scientists closer to finding a reliable biological marker for…
Medications used to treat type 2 diabetes and obesity, including well-known brands like Ozempic and Wegovy, may offer unexpected mental health benefits. These drugs belong to a class called GLP-1 receptor agonists, and a large new study found they are linked to fewer psychiatric hospital visits and less time off…
A major Cochrane review has found that drugs designed to target amyloid beta proteins in the brain are unlikely to provide meaningful benefits for patients. At the same time, these treatments appear to increase the risk of brain swelling and bleeding. Amyloid beta is a protein that builds up in…
Scientists have uncovered evidence that evolution has relied on the same genetic “cheat sheet” for more than 120 million years, raising the possibility that life on Earth may be more predictable than once believed. An international group of researchers led by the University of York and the Wellcome Sanger Institute…
Researchers at APC Microbiome Ireland, a leading research center at University College Cork, have taken a major step toward understanding how coffee benefits the body. For the first time, scientists have closely examined how coffee interacts with the gut-brain axis, the communication network that links the digestive system and the…
A growing body of research suggests that modern humans did not originate from a single location, but instead emerged through interactions among groups spread across different regions of Africa. Traditionally, scientists have explained where these populations lived based mainly on climate. New findings now point to another powerful influence: disease,…
Infrasound refers to extremely low-frequency sound waves, below 20 Hertz (Hz), which are generally beyond the range of human hearing. These vibrations can arise from natural events such as storms, as well as human-made sources like traffic and industrial equipment. In the animal world, some species rely on infrasound to…
Quantum mechanics is famous for its strange and often counterintuitive ideas. At very small scales, particles do not behave like everyday objects. Instead, they can exist in multiple states at once, a concept known as superposition. Physicists describe this behavior using a mathematical object called a wavefunction. Yet this picture…
The hippocampus plays a central role in how we form memories and navigate space. It helps convert short-term experiences into long-term memories, allowing us to store and build on what we learn. Scientists led by Magdalena Walz Professor for Life Sciences Peter Jonas at the Institute of Science and Technology…
In a new study, SFI Professor David Wolpert, SFI Fractal Faculty member Carlo Rovelli, and physicist Jordan Scharnhorst take a fresh look at a famous and unsettling idea in physics and cosmology known as the “Boltzmann brain” hypothesis. This concept suggests that our memories, perceptions, and observations might not reflect…
Have you ever felt your smartphone heat up after heavy use or watched the battery drop at the worst possible moment? A big reason is the electronic circuits and memory inside the device, which consume energy and release heat as they operate. At the most basic level, computer memory stores…
Astronomers at the University of Warwick have confirmed more than 100 exoplanets, including 31 newly identified worlds, using a new artificial intelligence system.
