| Getting fuel to an invading cell's front line Posted: 22 Mar 2022 12:42 PM PDT Invading armies need a steady supply of fuel and armaments. That's just as true when the invaders are cells, such as when tumor cells break away and spread to other parts of the body in a process called metastasis -- the most deadly part of cancer. Now, a study in C. elegans worms provides new insight into how invading cells deploy fuel to the front lines of invasion to power their break-through machinery. |
| Posted: 22 Mar 2022 12:09 PM PDT A series of studies on endangered species that make their homes on the border of Vietnam and China underscores the growing importance of transboundary conservation efforts in the face of climate change. As the world warms, many plant and animal species migrate from their traditional habitats, increasing the likelihood of local and global extinctions. |
| Researchers control brain circuits from a distance using infrared light Posted: 22 Mar 2022 12:09 PM PDT Scientists have developed the first non-invasive technique for controlling targeted brain circuits in behaving animals from a distance. The tool has the potential to solve one of the biggest unmet needs in neuroscience: a way to flexibly test the functions of particular brain cells and circuits deep in the brain during normal behavior. |
| Nature study: Ocean life may adapt to climate change, but with hidden costs Posted: 22 Mar 2022 12:09 PM PDT A new study shows that some ocean animals may be able evolve their way out of troubles caused by climate change -- but at a high cost. By artificially evolving 23 generations of a marine copepod, Acartia tonsa, a team of scientists found that the tiny creatures could adapt to the high temperatures and carbon dioxide levels forecast for the warming oceans. But to get there, the populations had to spend a lot of their genetic flexibility -- leaving them vulnerable to new stresses, like low food. |
| Trial use of soybean waste to tackle obesity Posted: 22 Mar 2022 12:08 PM PDT Scientists have found that fermented soybean waste, or okara, could improve fat metabolism and mitigate effects of diet-induced obesity. |
| Nanoparticle-based COVID-19 vaccine could target future infectious diseases Posted: 22 Mar 2022 12:08 PM PDT Just one dose of a new nanoparticle-based COVID-19 vaccine was enough to produce an immune response in animals on track with vaccines currently in clinical use. And with minor changes, researchers hope the same vaccine platform could target other infectious diseases. |
| Study reconsiders name of Peru's Machu Picchu Posted: 22 Mar 2022 12:08 PM PDT More than 110 years after Hiram Bingham's first visit to the site, researchers reviewed Bingham's original field notes, early 20th century maps of the region, and centuries-old land documents from different archives. Their findings suggest that less was known about the site than what was previously thought. |
| Seen and ‘herd’: Collective motion in crowds is largely determined by participants’ field of vision Posted: 22 Mar 2022 09:28 AM PDT Researchers have developed a new model to predict human flocking behavior based on optics and other sensory data. |
| New tool to accelerate drug discovery Posted: 22 Mar 2022 09:28 AM PDT New technology will accelerate drug development by allowing researchers a better look inside the cell membrane to observe how cells react to drugs. |
| Environmentally conscious consumers more likely to buy chicken raised on insects or algae Posted: 22 Mar 2022 09:25 AM PDT Eating chicken raised on a diet of bugs or algae may sound downright unappetizing to some, but there are ways to make the idea more palatable to at least one type of food shopper. Consumers who are environmentally aware will likely warm up to the idea of using alternative proteins like insect meal in poultry feed if they're given enough information about the health and environmental benefits, a new study shows. |
| Bionic wing flaps improve wind energy efficiency Posted: 22 Mar 2022 08:13 AM PDT Scientists show a bionic approach combining features of a seagull's wing with an engineered flow control accessory, known as a Gurney flap, can greatly improve wind turbine performance. To achieve the best aerodynamic performance, the scientists simulated the use of the combined flow control accessory in a variety of situations, including high and low angle of attack and pre- and post-stall scenarios. They compared their computational simulations to experimental results for an aircraft wing undergoing a dynamic stall. |
| Striking lane-like patterns found in bacteria populations Posted: 22 Mar 2022 08:13 AM PDT Researchers have found that competing strains of Escherichia coli bacteria form distinctive lane-like patterns as their populations grow. |
| Much more than average, single-cell analysis reveals heterogeneity in metal adsorption Posted: 22 Mar 2022 08:13 AM PDT A research team has reported an in-depth analysis of precious metal adsorption onto Galdieria sulphuraria algae. The combination of X-ray absorption fine structure spectroscopy and single-cell inductively coupled plasma mass spectrometry allowed the cell population behavior to be related to chemical interactions that occurred between the metals and the cell surface. The insight is expected to contribute to the development of environmentally friendly cell-derived approaches for metal recycling and wastewater treatment. |
| Hawaiian-Emperor undersea mystery revealed with supercomputers Posted: 22 Mar 2022 08:13 AM PDT Kinematic plate reconstructions and high-resolution global dynamic models developed to quantify the amount of Pacific Plate motion change associated with the Hawaiian -- Emperor Bend. Scientists are hopeful this basic research into Pacific Plate motion can be applied to other associated phenomena such as large earthquakes. |
| Posted: 22 Mar 2022 08:13 AM PDT Using multiple high-resolution satellite datasets, researchers found that tropical carbon loss has doubled over the past two decades due to excessive forest removal in the tropics. The tropics are an important ecosystem as they store massive amounts of carbon in their woody vegetation and soil -- but they have suffered from extensive forest clearance since 2001. The researchers analyzed the gross forest carbon loss associated with forest removal in the tropics during the 21st century. |
| 100g of cranberries a day improves cardiovascular health, study finds Posted: 22 Mar 2022 08:12 AM PDT A new clinical trial found daily consumption of cranberries for one month improved cardiovascular function in healthy men. |
| The shape of bacteria can make it a more effective, and useful predator Posted: 21 Mar 2022 08:58 AM PDT Scientists have found that a predatory bacterium, capable of invading and consuming harmful bugs such as E.coli and Salmonella, can sculpt its own shape to fit inside its prey. Scientists have shown that the curved (boomerang-like) shape of the bacterium, called Bdellovibrio bacteriovorus, is an important feature that affects its lifestyle, enabling it to efficiently invade, grow and live inside other bacteria. |
| Why groundwater is one of our most precious resources Posted: 21 Mar 2022 07:37 AM PDT From the Murray-Darling system to Great Artesian Basin, 'invisible' underground groundwater is often the only water supply available across the vast majority Australia where its annual contribution to GDP is estimated at more than $6.8 billion a year. However, overuse of groundwater during droughts and aquifer depletion has already seen water crises, including in Australia's 'food bowl' the Murray-Darling Basin (MDB), California and Cape Town in South Africa, with more likely to follow with groundwater management largely reactive and unlikely to avert more crises as climate change accelerates and populations grow. |
| Chef’s kiss: Research shows healthy home cooking equals a healthy mind Posted: 21 Mar 2022 06:19 AM PDT New research has found being confident in the kitchen is not only good for your taste buds: it's also good for your mental health. |
