Cancer diagnoses traditionally require invasive or labor-intensive procedures such as tissue biopsies. Now, research reveals a method that uses pulsed infrared light to identify molecular profiles in blood plasma that could indicate the presence of certain common cancers. In this proof-of-concept study, blood plasma from more than 2,000 people was analyzed to link molecular patterns to lung cancer, extrapolating a potential 'cancer fingerprint.' Read more ›

Nanoplastics are an increasing threat to the ecosystem; however, their mobility in the soil is still underexplored. Against this backdrop, researchers investigated the adsorption and aggregation behavior of nanoplastics in different types of soil under different pH conditions. The study offers new perspectives on the migration and environmental interactions of nanoplastics, while broadening our knowledge of pollution dynamics and soil contamination processes. Read more ›

Researchers analyzed trade-related risks to energy security across 1,092 scenarios for cutting carbon emissions by 2060. They found that swapping out dependence on imported fossil fuels for increased dependence on critical minerals for clean energy would improve security for most nations -- including the U.S., if it cultivates new trade partners.

American Sign Language (ASL) recognition systems often struggle with accuracy due to similar gestures, poor image quality and inconsistent lighting. To address this, researchers developed a system that translates gestures into text with 98.2% accuracy, operating in real time under varying conditions. Using a standard webcam and advanced tracking, it offers a scalable solution for real-world use, with MediaPipe tracking 21 keypoints on each hand and YOLOv11 classifying ASL letters... Read more ›

Wear and tear on plastic products releases small to nearly invisible plastic particles, which could impact people's health when consumed or inhaled. To make these particles biodegradable, researchers created plastics from plant starch instead of petroleum. An initial study shows how animals consuming particles from this alternative material developed health problems such as liver damage and gut microbiome imbalances. Read more ›

Milky seas are a rare bioluminescent phenomenon where vast areas of the ocean glow at night, sometimes for months. This glow, likely caused by Vibrio harveyi bacteria, has been reported by sailors for centuries but remains poorly understood due to its rarity and remote locations, mainly in the Indian Ocean. Researchers have compiled a 400-year database of sightings, using historical records and satellite data, revealing that milky seas are linked... Read more ›

Iron and its alloys, such as steel and cast iron, dominate the modern world, and there's growing demand for iron-derived products. Traditionally, blast furnaces transform iron ore into purified elemental metal, but the process requires a lot of energy and emits air pollution. Now, researchers report that they've developed a cleaner method to extract iron from a synthetic iron ore using electrochemistry, which they say could become cost-competitive with blast...

With the global prevalence of obesity on the rise, it is crucial to explore the neural mechanisms linked to obesity and its influence on brain and cognitive health. However, the impact of obesity on the brain is complex and multilevel. Read more ›

The NASA/ESA Solar Orbiter recently recorded the highest-ever concentration of a rare helium isotope (3He) emitted from the Sun. A Southwest Research Institute-led team of scientists sought the source of this unusual occurrence to better understand the mechanisms that drive solar energetic particles (SEPs) that permeate our solar system. SEPs are high-energy, accelerated particles including protons, electrons and heavy ions associated with solar events like flares and coronal mass ejections. Read more ›

Could it be that one of only three known markers directly targeting the DNA does not exist outside the realm of microbes? Now, researchers have demonstrated that this marker -- N4-methylcytosine (4mC) -- is essential for sperm development and maturation in the liverwort Marchantia polymorpha, a key organism in plant evolution.

Evidence shows that hunter-gatherers were crossing at least 100 kilometers (km) of open water to reach the Mediterranean island of Malta 8,500 years ago, a thousand years before the arrival of the first farmers. Read more ›

Osteoarthritis is the leading cause of disability and chronic pain worldwide, affecting an estimated 595 million people globally. Projections suggest that this number will rise to 1 billion by 2050. Despite its profound impact on individuals and societies, no disease-modifying treatments are currently available. Now, an international team of researchers has made new discoveries by studying the genetics of osteoarthritis in nearly 2 million individuals, uncovering hundreds of potential new... Read more ›

Researchers have identified nearly 300 genetic disorders that can be treated before or immediately after a baby is born. This 'treatable fetal findings list' could improve the diagnosis of genetic conditions in pregnancy and enhance the treatment options available for fetuses who have these conditions. Read more ›
