On Monday, Chipotle Mexican Grill shot down its over 2,000 restaurants for four hours to conduct a ‘virtual’ town hall meeting with its employees regarding steps it said it has decided to take to enhance food safety and regain the trust of consumers.

While speaking to over 50,000 employees, who were connected to Chipotle’s Denver headquarters through video, Steve Ells, the company’s founder and co-chief executive, said that people will come back.

While stressing his faith in the statement, he said that the company had no aim of making its growth sluggish this year.

In the company’s hour-long meeting, a wire-service reporter and a reporter from Fast Company were allowed, and the company tweeted a few statements made by its executives and pictures of them and employees.

Space Exploration Technologies (SpaceX) is preparing to launch its second rocket of 2016 in February. The California-based company has boosted the manufacturing operations for its Falcon 9 rockets. The enhanced production activities are aimed at meeting the requirements of SpaceX’s contracts with NASA and commercial companies, worth a total of over $8 billion.

According to Luxembourg-based satellite communications operator SES SA, which is a client of the technology entrepreneur Elon Musk-owned and operated SpaceX, the latter is planning its second launch in February 24, 2016. A comprehensive range of assessment and pre-flight substantiation are being concluded by SpaceX, as per a statement revealed by SES.

A new research on the jaw of Australopithecus sediba has revealed that the small, apelike species are likely to share food preferences with the Homo sapiens or modern humans. Homos and A. sediba specie also shared the limitation of not being able to chew hard foods, different from other australopiths.

The research was aimed at investigating the facial and dental formation of the specie, indicating about their diet. The investigation was carried out through a computer model of an A. sediba skull that was foremost found in 2008 in South Africa. The model was used to track the impact of various force simulations on strain and stresses.

Though the word gravity waves may sound somewhat similar to gravitational waves, and save a whole six characters for an even more concise tweet to mention “gravity” instead of “gravitational”, there is a lot of difference between the two.

Predicted over a century ago in Einstein’s theory, gravitational waves are ripples in spacetime, which are generated by the acceleration (or, indeed, deceleration) of massive objects in the cosmos. If a star bursts as a supernova, these waves carry energy away from the detonation at a speed almost equal to light.

A team comprised of researchers from different countries has claimed that fossil remains of two fish species that lived more than 90 million years ago have been discovered. The plankton-eating fish species belonged to genus called Rhinconichthys.

Rhinconichthys is extremely rare genus, and there is only species in the world that belong to the genus, said Kenshu Shimada, an author of the new research and a paleobiologist from the DePaul University. Previously, the only known species to the Rhinconichthys genus was found in England, Shimada added.

Don’t be surprised if you see a robotic cockroach doing some rescue works around a collapsed building because such a roach bot is going to be the future hero for trapped people. The unique invention is brainchild of UC Berkeley researchers.

The new cockroach robot is capable of running through tiny spaces in collapsed buildings, and that too at blazing speeds, as per the researchers. The roach bot has been designed with an aim to use it as search-and-rescue robobugs in buildings collapsed in disasters. The tiny robot can also help scientists understand the role of animals in soft robotics.
