Kavya Satish, 30, used to work as a teacher at a private school. She was married to Satish, an agriculturist-cum-realtor and a resident of Mookambikanagar near Machohalli forest gate off Tumakuru Road.According to the police, the body was found near Madanayakanahalli forest region in Nelamangala. The police suspect that she was beaten to death as her skull had a deep injury.Kavya had left home for the school on October 31, 2018, and never came back. Satish had filed a missing person complaint with Madanayakanahalli police. “Satish had mentioned the colour of her saree, her wristwatch and the lunch box that she carried,” police said.Her mobile phone was switched off and locals told cops that they didn’t see her heading towards the bus stand or any other place on the day she went missing, reports TOI.The police found Kavya’s half-burnt body near the forest area on Tuesday and informed her elder sister Soumya. The body matched with the descriptions of Kavya and had the same items mentioned in the police statement by her husband. Kavya’s family also identified personal belongings after reaching the crime spot.Soumya has lodged a complaint against Kavya’s husband and his family for allegedly murdering her sister.last_img read more

Asteroid warning Space rock speeding at 23100 kilometres per hour approaching Earth

first_imgAsteroid formation through planetary collisionDon Davis via University of FloridaAs NASA is busy developing their planetary defence weapon, a giant asteroid measuring 650 metres in diameter will whizz past Earth on September 14, 2019. This rogue space body named 2000 QW7 is apparently travelling at a speed of 23,100 kilometres per hour, and it will be flying past Earth at a safe distance of 3.3 million miles.NASA’s asteroid tracking department considers all rogue bodies passing at a distance within 92.9 million miles as near-earth objects (NEO). It means that even a small change in trajectory could elevate the vulnerability of a possible hit, and if such an event happens, a catastrophe on a global scale will be triggered.It should be noted that several factors in space are capable of increasing the possibilities of the earth being hit by rogue space bodies like asteroids. One such factor is a gravitational keyhole. A gravitational keyhole is an area in space where rogue space bodies get affected by the gravitational pull of nearby planets, and if 2000 QW7 passes through this keyhole, this asteroid could plummet right into the Earth’s surface resulting in massive devastation.A few days back, SpaceX founder Elon Musk had claimed that humans are not capable enough to defend themselves from possible asteroid hits that may happen in the near future. The South African billionaire made these remarks on Twitter when one of his followers asked whether asteroid Apophis will hit the earth in 2029. Musk assured that earth will be hit by a doomsday asteroid one day or the other, but current human technology is not developed enough to combat these threats.Earlier, Dr Iain McDonald, a top scientist Cardiff University’s school of earth and ocean sciences had also suggested that earth will face catastrophe due to a doomsday asteroid. As per McDonald, catastrophic events like asteroid hits are not confined to the past, and it will happen in the future too.last_img read more

Research shows crows comparable to humans when it comes to waiting

Crows demonstrate their cleverness with tools (w/ Video) Explore further The researchers, led by Dr. Valerie Dufour from the Universite de Strasbourg, began their study by training 12 birds to exchange tokens for food. They gave each bird a piece of food. Keeping their giving hand closed, they showed the birds the reward in their other hand. After a waiting period, the researchers opened their giving hand again. The birds then received the reward if they gave back the initial piece of food.The maximum waiting period the researchers used was five minutes and the quality of the reward varied in each exchange. What the birds did during the waiting period varied with some birds leaving the food on the ground or hiding it and checking on it during the time period.This study shows that the crows are able to wait before making a decision and that this behavior is not limited to only humans and apes. While the researchers believed that the birds would be able to wait a few seconds, they were surprised that the birds were able to wait as long as they did.The destructive behavior, such as hiding the food and checking on it, enabled the crows to wait a longer period of time. Those birds with the longest waiting times all displayed this particular destructive behavior. © 2011 PhysOrg.com More information: Corvids can decide if a future exchange is worth waiting for, Biol. Lett. Published online before print September 14, 2011, doi: 10.1098/rsbl.2011.0726AbstractEvidence for time-dependent calculations about future rewards is scarce in non-human animals. In non-human primates, only great apes are comparable with humans. Still, some species wait for several minutes to obtain a better reward in delayed exchange tasks. Corvids have been shown to match with non-human primates in some time-related tasks. Here, we investigate a delay of gratification in two corvid species, the carrion crow (Corvus corone) and the common raven (Corvus corax), in an exchange task. Results show that corvids success decreases quickly as delay increases, with a maximal delay of up to 320 s (more than 5 min). The decision to wait rests both on the quality of the prospective reward and the time required to obtain it. Corvids also apply tactics (placing the reward on the ground or caching it) that probably alleviate costs of waiting and distract their attention during waiting. These findings contrast previous results on delayed gratification in birds and indicate that some species may perform comparably to primates.via ABC (PhysOrg.com) — In a new study published in Royal Society’s Biology Letters, researchers have discovered that crows and raven birds show the same ability to complete delayed exchange tasks as monkeys and humans do.last_img read more
