Until now, scientists did not understand how supermassive black holes grew so large, so early in the universe. Neither did they spot 'black hole food' in large enough quantities to explain this rapid growth, until now, says a new study. ...
Researchers used functional magnetic resonance imaging to scan dogs' brains as they viewed varying numbers of dots flashed on a screen, and they received no training in number tasks. The results showed that the dogs' parietotemporal cortex responded to differences in the number of the dots.
Recording the first such quake on Mars in April this year, NASA's InSight Mission has detected 322 so far. While most are mild, of magnitudes that are barely felt on Earth, a couple of these Marsquakes have been big, up to nearly magnitude 4.
Scientists suspect a second black hole — about 1,00,000 times the Sun's mass — could be orbiting the only known supermassive black hole in our galaxy

These changes, for the most part, are fuelled by human-induced pollution. When carbon dioxide emissions from cars or power plants are absorbed by the oceans, it drives the water to become more acidic. However, natural factors are also contributing to the rising acidic levels, finds the study.
NASA has been scanning the planet to find the perfect landing site. And Arcadia Planitia is the most tempting one so far

This will help scientists better understand the workings of the Martian climate, giving them a more accurate picture of its ancient past and its ongoing evolution
According to the lead author of the study, social isolation and sensory deprivation, including the lack of navigation in large-scale space, could be the possible reasons, which contributed to the brain shrinking.
The holes measure 11 meters wide and one meter deep, on average, according to scientists who mapped the seabed. The survey was done to evaluate the feasibility of building a wind energy farm on the site

The new map provides evidence for these nuclear tests, say researches from University of Delaware
According to experts, these zones result from the loss of oxygen, and they are expanding due to climate change and pollutants from agricultural wastes
The night of the full moon is the only night of the month when the moon will rise around the sunset, shine brightly all night and then set around sunrise the following morning
The eruption created a steam and ash column to 12,000 feet above the island in New Zealand’s Bay of Plenty—a popular tourist destination; 47 people were on the island at the time of eruption on Monday afternoon
NASA zeroed in on the south pole as its landing site after the Lunar Reconnaissance Orbiter (LRO)—a robotic spacecraft circling Moon—provided a wealth of information on the region
Thanks to NASA’s Cassini Mission to Saturn, scientists now know that the cracks repeatedly widen and narrow as they dance to the rhythm of Saturn's gravity
Images taken by cameras aboard NASA's OSIRIS-REx spacecraft offer a detailed look at small-scale mass loss events; while the cause of this particle ejection continues to challenge scientists, the observations show that asteroids are far from being inert bodies.
The data shows that these winds come from a hole in the Sun's corona or the outermost part of the Sun's atmosphere and appear to be closer to its equator
The study provides evidence that planets can survive the explosive transformation of a star into a white dwarf as most planets were thought to not survive this transition.
The researchers found that across the 11 western states, of the $50.8 billion of total estimated flood damages during 1978 to 2017, atmospheric rivers accounted for 84% of these damages, exceeding 99% in some areas of the coastal states.
While their body size has declined, wing length has increased, shows an analysis of 70,716 North American migratory birds that died when they collided with buildings in Chicago over the past four decades
A dog is a reassuring, uncritical audience who will not mind if mistakes are made, say experts, adding that these findings could help schools develop dog-assisted strategies to support struggling young readers
Those who used chemical straighteners every 5-8 weeks were about 31% more likely to develop breast cancer, while permanent dye use was associated with a 9% higher risk.
The black hole seems to be enhancing star formation more than one million light-years away in multiple galaxies across massive distances
These lakes are formed during summers, as the ice begins to melt, resulting in “supraglacial” lakes forming on the surface of the ice. Many of these lakes drain through the cracks and crevasses in the ice sheet, weakening it further.
These mammals are naturally adept at removing and capturing carbon dioxide, and when they die, they sink deep into the ocean floor, taking with them their carbon reserves
Porn could affect the prefrontal cortex — a part of the brain which controls morality, willpower and impulse control. This region is underdeveloped in children, explaining why they have trouble controlling their impulses and emotions
The 85-mile stretch of land along the Mississippi River between New Orleans and Baton Rouge has been infamously nicknamed cancer alley owing to the high concentration of chemical plants, and the region's cancer cases
Occurring every decade or so, these dust storms blanket the entire planet in a dusty haze and a large number of thick clouds of dust or dust towers reach high into the air, say scientists.
The recent study follows a UN report, which says that greenhouse gas emissions continue to rise, despite scientific warnings and political commitment, and have increased at a rate of 1.5% per year in the last decade.
The theory challenges the widely-held notion that planets are formed only around a young star
The current level of carbon dioxide concentration in the atmosphere is 147% of pre-industrial levels in 1750, a time where fossil fuel and coal was unheard of.
The galactic center is covered in interstellar dust and to see past the dust, scientists rely on telescopes. The Murchison Widefield Array telescope has now shown images of what our galaxy would look like if human eyes could see radio waves.
The average global land and ocean surface temperature for October 2019 was 0.98°C, a value that was just 0.06°C short of the record-warm October set in 2015
William Romoser, an entomologist and professor emeritus at Ohio University, says he has observed insect-like forms, structured similarly to bees, as well as reptile-like forms -- both as fossils and living creatures on the planet
The neutron star was shrouded in dust from the supernova explosion that occurred 160,000 light-years away in a neighbouring galaxy, experts say.
Experts say the grey-patch disease strikes by altering the corals' defenses and will influence the health of future reefs.
The older method, which equates one dog year to seven human years, is a myth, say scientists.
The analysis by the US Government Accountability Office says 945 of 1,571 sites could face storm surges, wildfires, and sea-level rise.
While scientists have not yet detected liquid water directly, experts say they have found the next best thing: water in vapor form
Transgender children show a pattern of gender development associated with their current gender, says the study. How, and for how long a transgender child was treated as their assigned sex does not appear to affect their current gender identity and expression
Healthy coral reefs are remarkably noisy places and young fish home in on these sounds when they are looking for a place to settle. The study found recordings of such sounds doubled the total number of fish arriving at the patches of reef habitat
The complex mission will entail a rover collecting rock samples from the planet, getting it on a rocket to put it in Mars' orbit and then capturing it in a spaceship that will bring it to Earth
Until now, scientists had estimated the mass of an individual stellar black hole in the Milky Way at no more than 20 times that of the sun
