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

New research found that oncogene SET/TAF1, which was found to be a proto-oncogene of acute myeloid leukemia (AML), contributes to proper chromosome partitioning as a tension sensor. Additionally, abnormal SET protein disrupts tension sensor system at the centromere, leading to missegregation of the chromosomes and thereby cancer. These findings may lead to a discovery for a new kind of leukemia treatment. from Latest Science News -- ScienceDaily https://ift.tt/2mUWCMA

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

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

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

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

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

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.
