Czech lab grows mustard plants for Mars

PRAGUE Czech scientists have opened a lab to experiment growing food for environments with extreme conditions and lack of water, such as Mars. The "Marsonaut" experiment by scientist Jan Lukacevic, 29, and his team at the Prague University of Life Sciences is based on aeroponics—growing plants in the air, without soil, and limiting water use to a minimum. The plants grow horizontally from a vertical unit and are stacked one above the other to minimize space. Researchers experiment with light and temperature changes, Lukacevic said. The team has already succeeded in growing mustard plants, salad leaves, radishes and herbs like basil and mint. Scientists ate their first harvest last week. "They taste wonderful, because they grow in a controlled environment and we supply them with bespoke nutrients," said Lukacevic. Strawberries are the next crop planned. The main benefit of the growing method is that it uses 95 percent less water than normal plant cultivation ...

Calculating 'run and tumble' behavior of bacteria in groundwater

Bacteria in groundwater move in surprising ways. They can passively ride flowing groundwater, or they can actively move on their own in what scientists call "run and tumble" behavior. However, most numerical models of bacterial transport in groundwater stumble when it comes to calculating how bacteria move. As a first step in improving these models, scientists studied the movements of two kinds of microorganisms. They then factored those characteristics into a simple micro-scale transport model that more accurately predicted changes underground. from Phys.org - latest science and technology news stories https://ift.tt/2Nt1otJ

Zeroing in on food security as agricultural impacts of climate crisis become more apparent

Early this August, the U.N. Intergovernmental Panel on Climate Change issued yet another in a series of grave and disquieting reports outlining the extreme challenges placed on the Earth's systems by the climate crisis. Most IPCC reports and accompanying media coverage tend to emphasize greenhouse gas (GHG) emissions from energy and transportation sectors, along with the weather and sea-level impacts of climate change and their direct impact on vulnerable human populations. However, this particular report, the "Special Report on Climate Change and Land," presents a sobering set of data and analyses addressing the substantial contributions of agriculture to climate change and the ways the climate crisis is projected to jeopardize global food security if urgent action is not taken at the individual, institutional, industry, and governmental levels. from Phys.org - latest science and technology news stories https://ift.tt/36oqBhx

Losing intact tropical forests six times more devastating on climate: Study

MELBOURNE Losing intact tropical forests is six times more devastating on the climate than previously thought, according to researchers who suggest that preserving such lands with the help of indigenous people can bring climate mitigation benefits. The results of their study, published in the journal Science Advances, revealed that the clearance of intact tropical forests between 2000 and 2013 resulted in a much greater level of carbon emitted to the atmosphere than initially believed—with a 626 per cent increase in the calculated impact on climate. The researchers, including Sean Maxwell from the University of Queensland (UQ) in Australia, said this difference equated to two years of global land-use change emissions, and was previously unaccounted for due to a lack of full carbon accounting.  “Usually only ‘pulse’ emissions are considered—these are emissions released the instant intact forest is destroyed. Our analysis considers all impacts such as the effects of selective log...

Birds depend on bacteria for communication and mating: Study

WASHINGTON Birds use bacteria to produce odour, and if these microbes are altered, it could negatively impact their ability to communicate with others of its species or find a mate, according to a study. The researchers, including those from Michigan State University in the US, discovered that scents emitted by songbirds are produced by certain bacteria in their preen glands which help the birds identify each other. This is the first study proving that bacteria associated with birds produced volatile compounds causally related to avian behaviour, the researchers said. The study, published in the Journal of Experimental Biology, noted that if the odour producing bacteria are removed or changed, the bird may fail to express the correct information about its identity to others.  “Though several studies have demonstrated correlations between scent gland bacterial community structure and host animal odour profiles, none have systematically demonstrated a causal relationship,” the r...

New technology removes carbon dioxide from the air at any concentration level: Study

BOSTON Researchers have developed a new technology to capture carbon dioxide from a stream of air—virtually at any concentration level—an advance that may pave the way for new strategies to reduce atmospheric greenhouse gas levels. The researchers from the Massachusetts Institute of Technology (MIT) in the US said that while most methods of removing carbon dioxide from a stream of gas required higher concentrations—such as those found in the flue emissions from fossil fuel-based power plants—the new method could suck out the gas even when it was present in very low concentrations.  They added that the method required significantly energy, and could even suck out the greenhouse gas at the roughly 400 parts per million currently found in the atmosphere. In a study, published in the journal Energy and Environmental Science, the researchers described the device as a large, specialized battery with a stack of electrodes that absorbs carbon dioxide from the air passing over its surfa...

Asteroid or comet impact caused extinction during last ice-age: Study

WASHINGTON Researchers have found further evidence supporting the theory that an extraterrestrial body such as an asteroid or a comet may have crashed into the Earth almost 13,000 years ago, and caused the extinction of many large animals, and a likely decline in early human population. The study, published in the journal Scientific reports, noted that an asteroid or a comet hit the Earth, or blew up in the atmosphere 12,800 years ago, causing a period of extreme cooling that may have led to the extinction of more than 35 species including giant sloths, sabre-tooth cats, and mammoths in what is called the Younger Dryas climate event. The researchers, including those from the University of South Carolina (UofSC) in the US, found further evidence of a cosmic impact based on research done at White Pond near Elgin in the US.  The new study adds to the discovery of platinum spikes—an element associated with cosmic objects like asteroids or comets—in multiple places across the world,...

Parents’ behaviour influences infant levels of ‘bonding hormone’ oxytocin: Study

WASHINGTON The behaviour of parents may influence their children’s developing system of oxytocin—a hormone involved in social interaction and bonding in mammals—according to a study that highlights the importance of parenting in infant health. The researchers, including those from the Max Planck Institute for Human Cognitive and Brain Sciences in Germany, observed a free play interaction between 101 mothers and their five-month-old children.  They collected saliva samples from both the mother and the infant, and then a year later, when the child was 18 months old to quantify the oxytocin levels. The study, published in the journal Science Advances, noted that greater involvement by mothers during the play interaction may have the potential to upregulate the oxytocin system in their kids. The hormone oxytocin is actively involved in early social, perceptual, and cognitive processes, and it influences complex social behaviours, the study noted. The researchers said that some ce...

People judge women CEOs more harshly for ethical failures

NEW YORK Women CEOs do not always have it easy as researchers have found that people are less likely to support an organisation after an ethical failure if the business is helmed by a female. Female leaders, however, receive less negativity for general business failures, said the study published in the Journal of Personality and Social Psychology. "Our study found that consumers' trust in, and willingness to support, an organisation after a failure varied based on the gender of the organisation's leader and the type of incident," said lead author of the study Nicole Votolato Montgomery of the University of Virginia in the US.  "Women incur greater penalties for ethical transgressions because of persistent gender stereotypes that tend to categorise women as having more communal traits than men, such as being more likable, sensitive and supportive of others," Nicole Votolato said.  Across three experiments, the researchers examined how gender would influe...

Young moms more likely to have kids with ADHD: Study

CANBERRA Young mothers have a greater chance of having a child with attention deficit hyperactivity disorder (ADHD), warn researchers from the University of Australia.

"Young mums can have it tough, especially as they're adjusting to becoming a parent while they're still young themselves," Lee added. Published in the journal Nature's Scientific Reports, the study explored the genetic relationship between female reproductive traits and key psychiatric disorders. They found that the genetic risk of ADHD in children was strongly associated with early maternal age at first birth, particularly for women younger than 20. Using genetic data of 220,685 women v...

'How to spot a wormhole in space decoded'

NEW YORK Researchers have found a new method to determine if a wormhole exists in a certain region of space—an advance that may help spot the speculative entity which is thought to form a warped passage between two separate cosmic regions. The new method focuses on spotting a hypothetical wormhole around what's thought to be a super-massive black hole at the heart of the Milky Way galaxy called Sagittarius A*, the researchers, including those from the University at Buffalo in the US, said. The study, published in the journal Physical Review D, describes a technique that astronomers could use to hunt for a wormhole by looking for perturbations in the path of S2—a star that astronomers have observed orbiting Sagittarius A*. While there is no evidence of a wormhole existing around Sagittarius A*, the researchers said that it is a good place to look for a wormhole since these bridges are expected to require extreme gravitational conditions—such as those present at super-massive bla...

Driverless cars may lead to more traffic congestion: Study

MELBOURNE Driverless cars could worsen traffic congestion in the coming decades, partly due to drivers’ attitudes towards the emerging autonomous technology, and a lack of willingness to share their rides, according to a study. Using Adelaide city in Australia as a test model, the researchers surveyed over 500 commuters, including a mix of those who travel to work by car and public transport, and modelled the potential impacts. “Autonomous or driverless vehicles are likely to have profound effects on cities. Being able to understand their impact will help to shape how our communities respond to the challenges and opportunities ahead,” said Raul Barreto, from the University of Adelaide in Australia.

Dinosaur-killing meteorite instantly acidified the oceans: Study

WASHINGTON In a first, researchers have found that the dinosaur-killing meteorite that crashed into the Earth 66 million years ago may have instantly acidified the oceans by causing a release of excess sulphur into the atmosphere and the seas. The researchers, including those from Yale University in the US, said that the impact from the space rock pulverised sulphur-rich rocks, and caused the raining-out of sulphuric acid which may have led to increased ocean acidity. The study, published in the journal PNAS, is the first direct evidence that the Cretaceous-Paleogene extinction event—also called the K-Pg mass extinction event—coincided with a sharp drop in the pH levels of the oceans 66 million years ago—which indicates a rise in ocean acidity. The researchers analysed the chemical composition of fossilised foraminifera—tiny plankton that grow a calcite shell—from before, during, and after the K-Pg event, and generated data about the changes in marine environments over time.

New intervention may help ease young children's biases against gender-nonconforming peers

Worldwide, gender nonconformity is on the rise. Children who don't conform to their birth sex are often perceived less positively, which may harm their well-being. A new study of Chinese kindergarten- and elementary-school-age children looked at the development of biases against gender-nonconforming peers and tested an intervention to modify their biases. The study found that although children were indeed less positive toward gender-nonconforming peers than toward gender-conforming peers, showing children certain examples of gender-nonconforming peers reduced bias against them.

Crabs can work through maze and remember route to find food

LONDON: In a first, researchers have found that common shore crabs can work their way through a complex maze in order to find food, and can even remember it two weeks later. The researchers, including those from Swansea University in the UK, tested 12 crabs over four weeks, placing food at the end of the maze each time. They said that the maze had three dead ends, and to reach the end of the maze the crabs needed five changes in direction. According to the researchers, the findings can help in designing experiments to understand how changing ocean conditions may affect survival abilities of other marine animals. The study, published in the journal Biology Letters, revealed that the crabs steadily improved both in terms of the time taken to find the food at the end of the maze, and in the number of wrong turns taken.

Machine-learning analysis of X-ray data picks out key catalytic properties

Scientists seeking to design new catalysts to convert carbon dioxide (CO2) to methane have used a novel artificial intelligence (AI) approach to identify key catalytic properties. By using this method to track the size, structure, and chemistry of catalytic particles under real reaction conditions, the scientists can identify which properties correspond to the best catalytic performance, and then use that information to guide the design of more efficient catalysts. from Phys.org - latest science and technology news stories https://ift.tt/2JhXoLw

Antiquated dams hold key to water quality

All over the eastern part of the United States, thousands of small dams block the flow of water in streams and rivers, harkening back to colonial times. Originally constructed for energy and milling operations by settlers or companies, most of the milldams no longer serve human purposes. Now, many of these inactive dams are being removed by government and private agencies—driven by a need or hope of increasing public safety, reducing liability and improving aquatic habitats. from Phys.org - latest science and technology news stories https://ift.tt/35YtwNN

Revealing the nanostructure of wood could help raise height limits for wooden skyscrapers

There is increasing interest around the world in using timber as a lighter, more sustainable construction alternative to steel and concrete. While wood has been used in buildings for millennia, its mechanical properties have not, as yet, measured up to all modern building standards for major superstructures. This is due partly to a limited understanding of the precise structure of wood cells. from Phys.org - latest science and technology news stories https://ift.tt/2MD9Rv4
