| Everyone eats three extra cheeseburgers a day than they admit, study shows Posted: 19 May 2022 07:38 AM PDT Everyone eats the equivalent of three extra cheeseburgers a day than they admit -- regardless of their waistline, researchers have revealed. The study shows obese and thin people all fib about food to the same amount regardless of the number on the bathroom scale and this could be undermining national health advice. |
| Unlocking the secrets of killer whale diets and their role in climate change Posted: 19 May 2022 07:38 AM PDT Researchers have discovered new clues to understand how killer whales impact their environment. |
| Why baby leatherback marine turtles can't 'see the sea' Posted: 19 May 2022 07:38 AM PDT For most sea turtles, the journey to find the ocean from their nests is pretty straightforward. However, leatherback hatchlings more often crawl around in circles trying to find the ocean. Circling delays their entry into the ocean, wastes energy, and places them at greater danger from natural predators. Under different moon phases: bright light during full moon and only starlight under new moon, researchers have a better understanding of why this circling behavior happens and why it is most commonly observed in leatherbacks. |
| Using light and sound to reveal rapid brain activity in unprecedented detail Posted: 19 May 2022 05:54 AM PDT Biomedical engineers at Duke University have developed a method to scan and image the blood flow and oxygen levels inside a mouse brain in real-time with enough resolution to view the activity of both individual vessels and the entire brain at once. This new imaging approach breaks long-standing speed and resolution barriers in brain imaging technologies and could uncover new insights into neurovascular diseases like stroke, dementia and even acute brain injury. |
| Scientists develop 'off the shelf' engineered stem cells to treat aggressive brain cancer Posted: 19 May 2022 05:54 AM PDT Investigators have devised a novel therapeutic method for treating glioblastomas post-surgery by using stem cells taken from healthy donors engineered to attack GBM-specific tumor cells. This strategy demonstrated profound efficacy in preclinical models of GBM, with 100 percent of mice living over 90 days after treatment. |
| Standard test for multiple myeloma provides clues of a rare, more deadly type Posted: 19 May 2022 05:11 AM PDT A test for the common blood cancer multiple myeloma also holds clear clues that the patient has one of the most uncommon and deadly forms of this cancer, investigators say. |
| How cranberries could improve memory and ward off dementia Posted: 19 May 2022 05:11 AM PDT Researchers have found that eating cranberries could improve memory, ward off dementia, and reduce 'bad' cholesterol. The research team studied the benefits of consuming the equivalent of a cup of cranberries a day among 50 to 80-year-olds. They hope that their findings could have implications for the prevention of neurodegenerative diseases such as dementia. |
| Are people swapping their cats and goldfish for praying mantises? Posted: 19 May 2022 05:11 AM PDT Praying mantises have gained recent popularity as pets, sold at animal fairs and pet markets, but also collected in the wild by a fast-growing community of hobbyists and professional marketers. An overview of this market's dynamics reports on both problems and opportunities of the pet mantis market, like the absence of regulations, but also the potential of a stronger collaboration between hobbyists and scientists for biodiversity conservation. |
| Satellite monitoring of biodiversity moves within reach Posted: 19 May 2022 05:11 AM PDT Global biodiversity assessments require the collection of data on changes in plant biodiversity on an ongoing basis. Researchers have now shown that plant communities can be reliably monitored using imaging spectroscopy, which in the future will be possible via satellite. This paves the way for near real-time global biodiversity monitoring. |
| Puzzling features deep in Earth's interior illuminated Posted: 19 May 2022 05:11 AM PDT New research examines an unusual pocket of rock at the boundary layer with Earth's core, some three thousand kilometers beneath the surface. |
| New strategies to save rice, the world's most indispensable grain Posted: 19 May 2022 05:10 AM PDT Plants — they’re just like us, with unique techniques for handling stress. To save one of the most important crops on Earth from extreme climate swings, scientists are mapping out plants’ own stress-busting strategies. Biologists have learned what happens to the roots of rice plants when they're confronted with two types of stressful scenarios: too much water, or too little. These observations form the basis of new protective strategies. |
| Scientist uncovers clues to aging in mitochondria Posted: 18 May 2022 04:42 PM PDT Many age-related diseases share a common feature: the mitochondria of cells begin to malfunction. While the cause is not known, scientists have discovered a new mechanism of how mitochondria start to go wrong, which opens new doors for researchers to explore how to begin to fix the problem. |
| Study reveals imaging approach with potential to detect lung cancer earlier, at the cellular level Posted: 18 May 2022 02:15 PM PDT Researchers have found a way to identify lung cancer at the cellular level in real time during a biopsy, offering promise in the ability to detect the disease earlier and with more confidence. |
| Posted: 18 May 2022 02:15 PM PDT Abnormal tumor blood vessels promote cancer progression and treatment resistance. Researchers have developed two approaches to repair tumor blood vessels and they have devised a method to measure the effects of these approaches. Combining the approaches may be an effective strategy for fixing blood vessel abnormalities that make tumors difficult to treat. |
| Brain capital: A new investment approach for late-life well-being Posted: 18 May 2022 01:06 PM PDT Within many societies and cultures around the world, older adults are too often undervalued and underappreciated, according to a new article. This exacerbates many key challenges that older adults may face. It also undermines the many positive aspects of late life that are of value at both an individual and societal level. In the article, 'Investing in Late-Life Brain Capital,' a global team of experts propose a new approach to elevate health and well-being by optimizing late-life brain capital. |
| Sparking sustainable new chemical catalysts Posted: 18 May 2022 01:06 PM PDT New research could lead to the creation of new, sustainable catalysts based on tungsten oxide and similar compounds. The project used computational simulations to understand how tungsten oxide interacts with hydrogen at the molecular level and the findings were verified through lab experimentation. |
| Researchers magnify hidden biological structures with MAGNIFIERS Posted: 18 May 2022 01:06 PM PDT A research team has combined two emerging imaging technologies to better view a wide range of biomolecules, including proteins, lipids and DNA, at the nanoscale. Their technique brings together expansion microscopy and stimulated Raman scattering microscopy. |
| Accelerating the pace of machine learning Posted: 18 May 2022 01:06 PM PDT Machine learning happens a lot like erosion. Data is hurled at a mathematical model like grains of sand skittering across a rocky landscape. Some of those grains simply sail along with little or no impact. But some of them make their mark: testing, hardening, and ultimately reshaping the landscape according to inherent patterns and fluctuations that emerge over time. Effective? Yes. Efficient? Not so much. Researchers are now seeking to bring efficiency to distributed learning techniques emerging as crucial to modern artificial intelligence (AI) and machine learning (ML). In essence, the goal is to hurl far fewer grains of data without degrading the overall impact. |
| Synthesis of two-dimensional holey graphyne Posted: 18 May 2022 08:38 AM PDT A new type of carbon allotrope, holey graphyne, has semiconductor properties and is applicable in various fields such as photoelectronics, sensors, and water purification. |
| Caesarean births not linked to increased risk of food allergy during infancy Posted: 18 May 2022 07:17 AM PDT Caesarean births are not linked to an increased risk of food allergy during the first year of life, according to a new study. |
