Biologists track the invasion of herbicide-resistant weeds into southwestern Ontario

A team led by biologists have identified the ways in which herbicide-resistant strains of the invasive common waterhemp weed have emerged in fields of soy and corn in southwestern Ontario. The resistance, first detected in 2010, spread thanks to two mechanisms: either pollen and seeds of resistant plants were physically dispersed by wind, water and other means, or resistance appeared through the spontaneous emergence of mutations that then spread. from Latest Science News -- ScienceDaily https://ift.tt/2njjdlR

Heating the solar corona

The hot outer layer of the sun, the corona, has a temperature of over a million degrees Kelvin, much more than the surface temperature of the Sun which is only about 5500 degrees Kelvin. Moreover, the corona is very active and ejects a wind of charged particles at a rate equivalent to about one-millionth of the moon's mass each year. Some of these particles bombard the Earth, producing auroral glows and occasionally disrupting global communications. There are two important, longstanding, and related questions about the corona that astronomers are working to answer: how is it heated to temperatures that are so much hotter than the surface? And how does the corona produce the wind? from Phys.org - latest science and technology news stories https://ift.tt/2nR2PsP

Positive social relationships boost self-esteem: Study

NEW YORK Researchers have found that positive social relationships, support and acceptance help shape the development of self-esteem in people. "For the first time, we have a systematic answer to a key question in the field of self-esteem research: Whether and to what extent a person's social relationships influence his or her self-esteem development, and vice versa, and at what ages," said study author Michelle A. Harris from the University of Texas. "The answer to what age groups are across the life span," Harris said. For the study, published in the Journal of Personality and Social Psychology, researchers analysed 52 studies involving more than 47,000 participants (54 per cent female) looking at either the effect of self-esteem on social relationships overtime or the reverse effect.  The studies, all published between 1992 and 2016, included multiple countries like 30 samples from the US, four from Switzerland, three from Germany, two each from Australi...

'Blackhole shredding apart a star observed for the first time'

WASHINGTON In a first, researchers watched a supermassive black hole—weighing about 6 million times the Sun's mass—shred a star apart in a cosmic cataclysm called a tidal disruption event.  The discovery made using NASA's planet-hunting Transiting Exoplanet Survey Satellite (TESS)—with follow-up observations by NASA's Neil Gehrels Swift Observatory, and other facilitiesproduced the most detailed look of the star-destroying event. NASA said that tidal disruptions are incredibly rare, occurring once every 10,000 to 100,000 years in a galaxy the size of our own Milky Way, with only 40 such events observed so far. "TESS data let us see exactly when this destructive event, named ASASSN-19bt, started to get brighter, which we've never been able to do before," said Thomas Holoien, lead author of the study from the Carnegie Observatories in California. "Because we identified the tidal disruption quickly with the ground-based All-Sky Automated Survey for Supe...

Research looks at how environmental taxes can work for everyone, in Spain and beyond

Governments that impose taxes on carbon dioxide and other greenhouse gas emissions can benefit from a cleaner, more climate-friendly environment and a revenue stream that can be tapped to lower other taxes and create jobs. But environmental taxes may also exact an excessive financial burden on low-income households, which spend a much greater fraction of their budgets than richer households do on heating oil, natural gas, and electricity. This concern has limited the use of green taxes in Spain, where emissions are taxed at levels far below average for the European Union, which seeks to lower emissions across the continent to fulfill its 2015 Paris Agreement climate pledge. from Phys.org - latest science and technology news stories https://ift.tt/2m0mYw3

Less genes for a life in water

While whales and dolphins spend their entire life in the ocean, these air-breathing mammals actually evolved from terrestrial species. The transition from land to water in the ancestors of modern whales and dolphins about 50 million years ago was accompanied by profound anatomical, physiological, and behavioral adaptations that facilitated life in water. However, which changes in the DNA underlie these adaptations remains incompletely understood. To reveal them, researchers at the Max Planck Institutes of Molecular Cell Biology and Genetics and for the Physics of Complex Systems as well as the Center for Systems Biology Dresden systematically searched for genes that were lost in the ancestor of today's whales and dolphins. The research team discovered 85 gene losses, some of which likely helped whales to thrive in their new habitat. from Phys.org - latest science and technology news stories https://ift.tt/2mVlHGQ

'Second interstellar object ever discovered in solar system'

LONDON A new object from interstellar space has been found within the solar system, only the second such discovery of its kind, according to the International Astronomical Union (IAU). The object, given the name 2I/Borisov by the IAU, offers a tantalising glimpse beyond the solar system, and raises some puzzling questions, IAU said in a statement. On August 30 this year, amateur astronomer Gennady Borisov from MARGO observatory, Crimea, discovered the object with a comet-like appearance. The object has a condensed coma, and more recently a short tail has been observed, IAU said. Borisov made this discovery with a 0.65-metre telescope he built himself, according to IAU. After a week of observations by amateur and professional astronomers all over the world, the IAU Minor Planet Center was able to compute a preliminary orbit, which suggested this object was Interstellar—only the second such object known to have passed through the solar system. The orbit is now sufficiently well kn...

Croc-like carnivores terrorised dinosaurs 210 million years ago: Study

JOHANNESBURG Giant, predatory crocodile-like animals that lived during the Triassic period in southern Africa preyed on early dinosaurs 210 million years ago, scientists say. These predators, known as "rauisuchians" preyed on early herbivore dinosaurs and their mammal relatives living at the time, according to Rick Tolchard from the University of the Witwatersrand in South Africa. "These ancient fossils provide us with evidence of how at least two predator species hunted these vegetarian dinosaurs 210 million-years-ago," Tolchard said. "It is amazing to follow the clues left behind in fossilised teeth, jaws, limbs and other fossils to help us tell the ancient story of life in southern Africa," he said. The fossils, described in the Journal of African Earth Sciences, include teeth, pieces of jaws, hind limbs and body armour, all of which can be described as parts of rauisuchians. Rauisuchians are closely related to crocodiles as we know them today. Th...

Brain pathway that lets us forget 'unnecessary memories' found

Tokyo A group of neurons in the brain's hypothalamus is inhibited during rapid eye movement (REM) sleep, contributing to the brain's ability to forget "unnecessary" memories, according to a study. The results, published in the Journal Science, offers insights into the poorly understood mechanisms behind the regulation of memory during sleep. Our brains are busy filtering and processing the day's experiences before consolidating them into memory when we rest, the study noted. Since not all of our experiences are "worth remembering," forgetting is a critical aspect in memory regulation. According to the researchers, including Shuntaro Izawa from Nagoya University in Japan, forgetting is an active process that allows for the removal of overloaded and unnecessary memories through synaptic renormalization—a process which only occurs while we sleep. A group of nerve cells called the Melanin-concentrating hormone (MCH) neurons, found exclusively in the hy...

Could Venus have been habitable?

Venus may have been a temperate planet hosting liquid water for 2-3 billion years, until a dramatic transformation starting over 700 million years ago resurfaced around 80% of the planet. A study presented today at the EPSC-DPS Joint Meeting 2019 by Michael Way of The Goddard Institute for Space Science gives a new view of Venus's climatic history and may have implications for the habitability of exoplanets in similar orbits. from Phys.org - latest science and technology news stories https://ift.tt/2LHMCQo

Surface melting causes Antarctic glaciers to slip faster towards the ocean: Study

LONDON The water from melting Antarctic glaciers, flowing through the ice and beneath them, is rapidly accelerating further thawing of the continent's ice sheets towards the sea, according to a study. The study, published in the journal Nature Communications, is the first time researchers have found that melting on the surface impacts the flow of glaciers in Antarctica. Researchers, including those from the University of Sheffield in the Uk, used imagery and data from satellites along with regional climate modeling and found that meltwater is causing some glaciers to move 100 per cent faster than average—by up to 400 meter per year. According to the researchers, gravity causes glaciers to move downhill with the internal deformation of ice, and by sliding over the ground beneath them—a process lubricated by liquid water called basal sliding. The study shows that the movement of glaciers in the Antarctic Peninsula coincides with spikes in snowmelt.  The researchers add that thi...

Flavoured e-cigarettes may worsen asthma symptoms: Study

MELBOURNE The flavours used in some e-cigarettes may cause allergy in airways, worsening the severity of diseases such as asthma, according to a study. In a first, researchers including those from the University of Technology Sydney (UTS) in Australia, used the model of asthma to investigate the effect of popular e-cigarette flavours both with and without nicotine. The study, published in the journal Scientific Reports, noted that the use of e-cigarettes has dramatically increased in the last few years with an estimated nine per cent of 18-24 year olds in the US currently using the devices. The results of the study indicate that some flavoured e-cigarettes—even when they do not contain nicotine—may alter the function of respiratory pathways affected by allergic disease. "This is especially important for those with respiratory disease, who are vulnerable to the effects of smoking," said David Chapman, UTS researcher and lead author of the study. He added that the majorit...

'Rainfall in Indonesia's islands linked to global climate'

WASHINGTON The rainfall in some of Indonesia's islands such as Sumatra, Java, and Borneo affects the climate of regions that are even thousands of miles away, according to a new study. Sumatra, Java, Borneo, and Papua New Guinea, along with a clutch of smaller islands are part of what is known as the "Maritime Continent," which, according to the researchers, experiences significant rainfall including "periodic monsoonal rain, and flash flooding."   In the study, published in the Journal of Atmospheric Sciences, researchers revealed details of the connection between a larger atmospheric phenomenon called the Madden-Julian Oscillation (MJO), and the daily patterns of rainfall in the Maritime Continent. The MJO, the study noted, circles the globe around the tropics and can affect weather on weekly to monthly time scales, bringing cloudy and sunny periods alternatively. The researchers, led by atmospheric scientist Giuseppe Torri at the University of Hawaii (UH...

How climate affects shape of rivers decoded

London, September 21 In a first, researchers have found the distinct signature change in the shape of rivers as regions across the world change from humid to arid due to the climate crisis. The study, published in the journal Nature, looked at changes in the path one makes when walking from a river’s source to its mouth as the stream descends in elevation—a measure called the ‘river long profile.’                The researchers, including those from the University of Bristol in the UK, noted that for some rivers this path descended steeply out of the higher lands, and flattened out in the lowlands, giving the river a long profile that was a concave up shape. “This is similar to the shape of the inside of a bowl as you trace it from the inside rim to the bottom,” Katerina Michaelides, co-author and hydrologist at the University of Bristol in the UK, told PTI in an email. In contrast, she added that a ‘straight long pr...
