(IANS) US researchers have discovered a new bird fossil which showed that a  unique brain shape may be the reason why the ancestors of living birds survived the mass extinction that claimed all other known dinosaurs 66 million years ago. A team from the University of Texas at Austin, the US, discovered the fossil, which is nearly 70 million years old and has a nearly complete skull -- a rare occurrence in the fossil record that allowed the scientists to compare the ancient bird to birds living today. The team published the findings in the journal Science Advances. The fossil is a new specimen of a bird named Ichthyornis, which went extinct at the same time as other non-avian dinosaurs and lived in what is now Kansas during the late Cretaceous period. Ichthyornis has a blend of avian and non-avian dinosaur-like characteristics, including jaws full of teeth but tipped with a beak. The intact skull let Torres and his collaborators get a closer look at the brain. "Living birds h

  Science News Roundup: International Space Station thrown out of control by misfire of Russian module -NASA; Russia blames software glitch after space station briefly thrown out of control and more The Government Accountability Office (GAO) said it "denied the protest arguments that NASA acted improperly in making a single award to SpaceX." International Space Station thrown out of control by misfire of  Russian  module -NASA The International Space Station (ISS) was thrown briefly out of control on Thursday when jet thrusters of a newly arrived  Russian  research module inadvertently fired a few hours after it was docked to the orbiting outpost,  NASA  officials said. The seven crew members aboard - two  Russian  cosmonauts, three  NASA  astronauts, a  Japanese  astronaut, and a  European  space agency astronaut from  France  - were never in any immediate danger, according to  NASA  and  Russian  state-owned news agency RIA.

  First indication of creature life on Earth might be a wipe fossil  A Canadian geologist might have tracked down the soonest fossil record of creature life on Earth, as indicated by a report distributed Wednesday in the diary Nature.  Around a billion years prior, a locale of northwest Canada currently characterized by steep mountains was an ancient marine climate where the remaining parts of old wipes might be protected in mineral silt, the paper says.  Geologist Elizabeth Turner found the stones in a distant area of the Northwest Territories available simply by helicopter, where she has been unearthing since the 1980s. Slender areas of rock contain three-dimensional constructions that look like current wipe skeletons.  "I accept these are antiquated wipes — just this sort of creature has this kind of organization of natural fibers," said Joachim Reinter, an agrobiologist and master in wipes at Germany's University of Gottingen, who was not associated with the examinati

  Scientists upturn understanding of how key hormones act in cells Researchers at the University of Virginia School of Medicine have overturned conventional wisdom on the workings of vital hormone receptors within cells, a finding that could boost drug development for diabetes and related metabolic disorders, cancer and other diseases. The scientists in UVA's Department of Pharmacology outline an entirely new paradigm to explain the activation of a type of hormone receptor, known as Type II receptors, found inside our cells' nuclei. These receptors play important roles in our body's use of cholesterol and glucose, among other critical processes. "Nuclear receptors are the only class of DNA-binding proteins that are druggable. Drug development has been focused exclusively on designing artificial hormones that would replace the natural ones and activate the receptor because everyone believed that binding of the receptor to DNA was constant," senior researcher Irina

A little atom smasher is being created in China that can "enormously" grow human comprehension of the secrets of life and development  Albeit the free-electron laser itself isn't new, the group had the option to diminish the size of the office from hundreds or even thousands to only 12 meters.  Researchers at Shanghai Institute of Optics and Micromechanics have made the principal smaller atom smasher equipped for fueling a free electron laser, correspondence Last Friday the Chinese Academy of Sciences (ACC).  The gadget permits the assessment of issue at the degree of particles and iotas, and vows to convey "progresses in different disciplines, like physical science, science, underlying science, medication, materials science, energy and the climate," the life form declares.  "The properties of the free-electron laser, including very high goal rates regarding reality and solid super high brilliance, make it conceivable to get 3D and multi-modular pictures of

  The human digestive tract It is comprised of in excess of 40 m2 of texture, with a huge number of folds on its inside surface that look like valleys and mountain tops, to accomplish, among different goals, increment the assimilation of supplements. This organ has the distinction of being in consistent recharging, which infers that around at regular intervals every one of the cells of its inward divider are restored to guarantee legitimate gastrointestinal capacity. As of recently it was realized that this reestablishment was conceivable because of the undifferentiated organisms that are safeguarded in the purported tombs or valleys digestive, and that lead to new separated cells. In any case, the interaction that prompts the curved state of the sepulchers and the relocation of new cells into the pinnacles gastrointestinal, as of recently it was obscure. Tries different things with research facility organoids or little digestion tracts and 3D models have made it conceivable to interpr

Japanese scientists presented a method of moving objects with sound waves Scientists from Japan  have presented  a new method for manipulating objects at a distance. This is a “sound trap” – objects can be moved using sound waves. Researchers at the University of Tokyo Metropolitan University have unveiled a new  technology  that allows small objects to be moved contactlessly using sound waves. They used a hemispherical array of ultrasonic transducers to create three-dimensional acoustic fields that held and lifted a small polystyrene ball from the surface. Although they used a method similar to a laser trap, it can be adapted to a wider range of particles and materials. Biologists and chemists have been using light to move microscopic objects for several years. In fact, part of the Nobel Prize awarded to Arthur Eshkin was for excellence in the development of optical tweezers. This is a device with which you can move objects using laser light. Therefore, the researchers presented acous

 Overall semiconductor chip deficiency to hit assembling of iPhones  Robert Besser  Apple Inc said on Tuesday that the worldwide chip deficiency could before long influence iPhone creation, with declining income development and bringing down the worth of its offers  Apple leaders expect twofold digit income for the final quarter, however beneath the 36.4% development rate in the just-finished second from last quarter  During a financial backer call, Chief Executive Tim Cook said that chips are utilized in supporting parts expected to make the organization's iPhone  CUPERTINO, California: Apple Inc said for this present week that the worldwide chip lack could before long influence iPhone creation, with declining income development and bringing down the worth of its offers.  Apple had before said that the chip deficiency could diminish deals by $3 to $4 billion.  Further, Apple leaders expect twofold digit income for the final quarter, however beneath the 36.4% development rate in th

 Here's the full story behind Bitcoin Lightning's 'rebound  There was once a period when scaling Bitcoin was the following formative advance. It filled the ascent of the Bitcoin Lightning Network in 2018. After some time, notwithstanding, the publicity and usefulness of the L2 installments convention have become ancient history. Regardless of whether it is the store-of-significant worth story or Bitcoin being named as 'computerized gold,' very few theorists are presently stressed over its accreditations as a method of exchange.  Between February 2020 and 2021, its development likewise wasn't actually fantastic, with the all out limit ascending from 886 BTC to only 1095 (23%). But, it very well may be an ideal opportunity to investigate the condition of lightning by and by as there have been a couple of changes.  Bitcoin Lightning strikes back  Since the start of March 2021, Bitcoins locked on the Lightning Network have explanatorily risen, nearly multiplying its
