An unexpected sugary snack can give bees a little buzz and appears to lift their mood, even making them optimistic, according to research that suggests pollinators have feelings, too. Since emotions are subjective and difficult to measure—particularly in animals—researchers looked at how bees’ behavior changed after they were given a sip of sucrose solution.
Saving up excess solar and wind energy for times when the sun is down or the air is still requires a storage device. Batteries get the most attention as a promising solution although pumped hydroelectric storage is currently used most often. Now researchers are advancing another potential approach using sugar alcohols—an abundant waste product of the food industry—mixed with carbon nanotubes.
Results of a new study by environmental health scientists suggest that inexpensive cloth masks worn by people who hope to reduce their exposure to air pollution vary widely in effectiveness and could be giving users a false sense of security, especially in highly polluted areas.
Researchers are proposing a new “hydricity” concept aimed at creating a sustainable economy by not only generating electricity with solar energy but also producing and storing hydrogen from superheated water for round-the-clock power production.
A new study by researchers heightens concerns over the detrimental impact of air pollution on hippocampal metabolites as early markers of neurodegeneration in young urbanites carrying an allele 4 of the apolipoprotein E gene (APOE). This is associated with the risk for Alzheimer disease (AD) and a susceptibility marker for poor outcome in traumatic brain injury (TBI) recovery.
Imagine creating artificial plants that make gasoline and natural gas using only sunlight. And imagine using those fuels to heat our homes or run our cars without adding any greenhouse gases to the atmosphere. By combining nanoscience and biology, researchers led by scientists at University of California, Berkeley, have taken a big step in that direction.
Two prominent scientists with drastically different views on the relationship of science and religion – Richard Dawkins and Francis Collins – have an equally different influence on these views among people who are unfamiliar with their work, according to new research from Rice University and West Virginia University.
Aitana Lertxundi has conducted her research work within the framework of the INma (Childhood and Environment) programme led by Jesús Ibarluzea of the Department of Health of the Government of the Basque Autonomous Community (region). The aim is to assess how exposure to environmental pollution during pregnancy affects health and also to examine the role of diet in physical and neurobehavioural development in infancy. The study focusses on the repercussions on motor and mental development during the first years of life caused by exposure to the PM2.5 and NO2 atmospheric pollutants.
Sometimes you just want beef, but beef is high in omega-6 fatty acids and low in the omega-3 type. Conversely, different types of fish are high in omega-3, but we all know they don’t compare to that tasty burger flavor. So what’s a beef lover to do, well if you’re in China you might have some options! Chinese scientists have reared beef rich in the beneficial fatty acids associated with fish oils.
When the government first changed policy to require ethanol in gasoline, we were told it would reduce our carbon footprint. Then food prices rose significantly and corn in particular saw the largest price rise. This was because corn is a staple in production of almost any other food from eggs to beef, but the policy made environmental sense. Well it made sense, until you found out that the new policy also took into account people eating less.
Alternative fuels have a few large problems making them horrible options over oil (which is already a horrible choice). However, researchers may have finally eliminated one of those problems, cost. The team has invented a novel pretreatment technology that could cut the cost of biofuels production by about 30 percent or more by dramatically reducing the amount of enzymes needed to breakdown the raw materials that form biofuels.
You really don’t hear much about mass die-offs from mainstream news outlets; this might make you think they don’t happen that often. However, an analysis of 727 mass die-offs of nearly 2,500 animal species from the past 70 years has found that such events are increasing among birds, fish, and marine invertebrates. At the same time, the number of individuals killed appears to be decreasing for reptiles and amphibians, and is unchanged for mammals.
Solar panels, they are big, heavy, cannot flex, and are still very inefficient. While efficiency isn’t the big issue, flexibility has relegated solar panels to rooftops and solar farms. Well that is until now, researchers have just invented a new way to spray solar cells onto flexible surfaces using miniscule light-sensitive materials known as colloidal quantum dots (CQDs)—a major step toward making spray-on solar cells easy and cheap to manufacture.
How much does global warming really cost the world? Determining the Social Cost of Carbon helps put a actual dollar value on the climate damages per ton of CO2 released, and is used by — among others — policymakers to help determine the costs and benefits of climate policies. Remember, even on a global scale, the bottom line will always be profit. But now a group of economists and lawyers urge several improvements to the government’s Social Cost of Carbon figure that would impose a regular, transparent and peer-reviewed process to ensure the figure is reliable and well-supported by the latest facts.
Global warming, it’s a bigger deal than some people seem to realize. For years science has pointed to the increased carbon dioxide output as the main reason for man-made global warming. However, there has been no evidence to directly link CO2 output to global warming, well until now. Research has identified, for the first time, how global warming is related to the amount of carbon emitted.
While everyone (but seemingly the media) is on basically the same page with the fact that global warming is a human caused problem — and one we need to fix the effects of this change are still coming to light. Human-induced changes to Earth’s carbon cycle – for example, rising atmospheric carbon dioxide and ocean acidification – have been observed for decades. However, a new study showed human activities, in particular industrial and agricultural processes, have also had significant impacts on the upper ocean nitrogen cycle.
So here’s something you don’t see everyday. Blu-ray disks, you know the stuff we use for video games or DVDs also improve the performance of solar cells—suggesting a second use for unwanted discs—according to new research from Northwestern University. As surprising as this was, there is even better news, we know why they improve performance.
Global warming, nothing new with that and it’s here to stay for now. But while computer models churn out bleak forecasts for the planet’s future, we also have a more conceptual understanding of what is happening as humans pump carbon dioxide into the air. Unfortunately the traditional conceptual understanding of carbon dioxide wrapping the planet in a sort of blanket that traps more heat is not quite right.
While the world waits for a better battery (and a energy grid system that doesn’t require constant power making), scientists are hard at work trying to teach old fuels a new trick. Thankfully an international team of bioengineers has boosted the ability of bacteria to produce isopentenol, a compound with desirable gasoline properties. The finding, if it is not obvious, is a significant step toward developing a bacterial strain that can yield industrial quantities of renewable bio-gasoline.
Hold on to your hats folks, we can all agree that most of the concerns about climate change have focused on the amount of greenhouse gases that have been released into the atmosphere. But in a new study a group of researchers have found that circulation of the ocean plays an equally important role in regulating the earth’s climate. Keep in mind this doesn’t mean global warming isn’t a man-made problem, please.
We have all probably seen stories from China on the horrid air pollution there. Accompanying those reports of course are the statistics for air pollution that deaths have caused. For the record, the World Health Organization estimated that ambient air pollution caused 3.7 million premature deaths (worldwide) in 2012 alone – yet what exactly happens to your body when it encounters pollutants?
Solar cells are inefficient, it’s a sad fact. With todays technology they boast about a 10-15% efficiency, compare that to todays gas engine at roughly 20-25% and you can see it’s not quite up to par. Well that could all change very soon thanks to a new method for transferring energy from organic to inorganic semiconductors. This could boost the efficiency of widely used inorganic solar cells to as close as 100% efficiency as they can get.
Maybe I’m dating myself here, but ever see the swamp thing movie, television show, or even the comic? Call me picky, after all we are talking about a human/plant hybrid, but he never needed to talk. I know, some of you are probably rolling your eyes at me given it’s a comic, movie or tv show [depending on your level of geek], but come on, this is science!
