| On the road to cleaner, greener, and faster driving Posted: 18 May 2022 08:38 AM PDT Researchers have developed a technique to control a fleet of autonomous vehicles as they approach and pass through a signalized intersection in a way that reduces fuel consumption and greenhouse emissions from idling and stop-and-go traffic, while improving travel speeds. |
| Rainforest trees may have been dying faster since the 1980s because of climate change Posted: 18 May 2022 08:38 AM PDT Tropical trees in Australia's rainforests have been dying at double the previous rate since the 1980s, seemingly because of climate impacts, according to the findings of a long-term international study. This research has found the death rates of tropical trees have doubled in the last 35 years, as global warming increases the drying power of the atmosphere. |
| Oat reference genome: Insights into a uniquely healthy cereal crop Posted: 18 May 2022 08:38 AM PDT Cultivated oat (Avena sativa L.) is an old crop thought to have been domesticated over 3,000 years ago, while growing as a weed in wheat and barley fields. Oat has a low carbon footprint, substantial health benefits and the potential to replace animal-based food products. However, lack of genome resources has prevented the application modern methods of plant breeding. An international research team now presents a high-quality reference genome of A. sativa and its most closely related wild relatives. |
| Posted: 18 May 2022 08:33 AM PDT In the wild, it might seem like male animals run the show. But researchers have laid a new framework to assess power distribution between the sexes, and its application has shown that in some animal species, females rule the roost and their paths to power look very different from that of their male counterparts'. |
| Scallops swim into illuminated fishing pots Posted: 18 May 2022 07:18 AM PDT Scallops are drawn to illuminated fishing pots like moths to a flame. The study examined the effect of LED lights on crab and lobster pots used by fishing boats off the coast of Cornwall, UK, and the research team was stunned by the results. More than 500 scallops were caught -- 99.6% of them in pots with lights. |
| At-risk sea life in the Atlantic needs better protection from an increase in shipping Posted: 18 May 2022 07:18 AM PDT New research has shown a dramatic increase in shipping in the North East Atlantic. Scientists now warn that more monitoring in the area is required to help protect sea life on the at-risk register. |

| Rocket engine exhaust pollution extends high into Earth's atmosphere Posted: 17 May 2022 08:22 AM PDT Researchers assessed the potential impact of a rocket launch on atmospheric pollution by investigating the heat and mass transfer and rapid mixing of the combustion byproducts. The team modeled the exhaust gases and developing plume at several altitudes along a typical trajectory of a standard present-day rocket. They did this as a prototypical example of a two-stage rocket to transport people and payloads into Earth's orbit and beyond and found the impact on the atmosphere locally and momentarily in the mesosphere can be significant. |
| Improved wind forecasts save consumers millions in energy costs Posted: 17 May 2022 08:22 AM PDT Scientists determined that by increasing the accuracy of weather forecasts over the last decade, consumers netted at least $384 million in energy savings. The researchers based their predictions on NOAA's High Resolution Rapid Refresh model, which provides daily weather forecasts for every part of the U.S. These include wind speed and direction data, which utilities can use to gauge how much energy their turbines will produce. |
| Study identifies cellular 'chaperone' for zinc Posted: 17 May 2022 08:22 AM PDT A team has described and characterized the first zinc metallochaperone: a protein that puts zinc into other 'client' proteins. The findings shed light on the public health issue of zinc deficiency and open an entirely new area of biology for exploration. |
| Phage therapy: A model to predict its efficacy against pathogenic bacteria Posted: 17 May 2022 08:17 AM PDT Antibiotic resistance represents a major public health challenge, associated with a high mortality rate. While bacteriophages -- viruses that kill bacteria -- could be a solution for fighting antibiotic-resistant pathogens, various obstacles stand in the way of their clinical development. To overcome them, researchers have developed a model to better predict the efficacy of phage therapy and possibly develop more robust clinical trials. |
| Change of temperature causes whole body reprogramming Posted: 17 May 2022 06:48 AM PDT Human beings, like most organisms, are constantly exposed to alternating colder or warmer temperatures. These environmental variations cause striking metabolic effects and require constant adaptations. While some of these adaptations confer certain beneficial effects on health, the impact of cold and warmth on the various organs in a whole-body context was not known. |
| Posted: 17 May 2022 06:48 AM PDT The capabilities of complex microbial communities are used for numerous biotechnological processes. This requires special compositions of the microbial communities. However, these are often unstable and susceptible to disruption. Researchers have now developed a 'mass transfer method with a loop' that can stabilize microbial communities in the long term. |
| Chimpanzees combine calls to form numerous vocal sequences Posted: 17 May 2022 06:48 AM PDT Compared to the complex use of human language, the way animals communicate with each other appears quite simple. How our language evolved from such a simple system, remains unclear. A group of researchers has now recorded thousands of vocalizations from wild chimpanzees in Taï, Ivory Coast. They found that the animals produced hundreds of different vocal sequences containing up to ten different call types. The order of calls in these sequences followed some rules, and calls were associated with each other in a structured manner. The researchers will now investigate if this structure may constitute a step towards human syntax and if chimpanzees use these sequences to communicate a wider range of meanings in their complex social environment. |
| Magnetic resonance makes the invisible visible Posted: 17 May 2022 06:48 AM PDT Researchers have developed an advanced NMR (Nuclear Magnetic Resonance) method to monitor fast and complicated biomolecular events such as protein folding. |
| Ecological functions of streams and rivers severely affected globally Posted: 17 May 2022 06:48 AM PDT Agriculture, loss of habitat or wastewater effluents -- human stressors negatively impact biodiversity in streams and rivers. Very little is known yet about the extent to which their capacity for self-purification and other essential ecosystem services are also impacted. An international research team has synthesized the globally available research on this topic in a meta-analysis. This study provides new initiatives for improved water management. |
| Deep ocean warming as climate changes Posted: 17 May 2022 05:30 AM PDT Much of the 'excess heat' stored in the subtropical North Atlantic is in the deep ocean (below 700m), new research suggests. |
| Validation brings new predictive capability to global megafire smoke impacts Posted: 17 May 2022 05:30 AM PDT New research modeling smoke from two recent megafires sets the stage for better forecasting of how emissions from these global-scale events will behave and impact temperatures. As huge wildfires become more common under climate change, increased attention has focused on the intensity and duration of their emissions, which rival those of some volcano eruptions. |
| New method melds data to make a 3-D map of cells' activities Posted: 16 May 2022 06:31 PM PDT Engineers are using a cell's surroundings to help biologists make more sense of gene expression information.
