The US Justice Department's consumer protection unit has been investigating a norovirus outbreak at a Chipotle restaurant in California. This has indicated that a recent probe launched by federal prosecutors in California has been grabbing a lot of attention at Washington headquarters.

In the wake of a series of foodborne illnesses, Chipotle Mexican Grill has been under a lot of scrutiny. All this has resulted into a decline in Chipotle’s shares and a fall in its fourth-quarter same-store sales.

On Wednesday, Chipotle revealed that the US Attorney's Office for the Central District of California had served it with a grand jury subpoena in December under a criminal investigation carried out by that office and the Food and Drug Administration.

SpaceX has announced that the company is planning to land its Falcon 9 rocket that is scheduled to be launched on January 17, 2016, on a drone ship, which is an autonomous floating platform.

The rocket is scheduled to take off from the Vandenberg Air Force Base in California and will be boarded with the Jason-3 satellite of NASA space agency. However, this time the rocket will land back in the ocean and not a launch pad on ground.

Several members of scientific community think human species have entered a new geologic era: the Anthropocene Epoch.

A report published Thursday in journal Science suggested that use of plastic, concrete and other fossil fuels that we burnt has changed the planet enough to declare the beginning of a new era and end of the thousands of years old Holocene Epoch.

Last about seven decades played a vital role in altering the earth. In the time, humans not only went far from our Holocene ancestors, but also took our planet towards a very tough phase, according to the report.

Do you tend to sneeze when flowers around you bloom during the spring or a cat comes nearby? Well, researchers at the Max Planck Institute for evolutionary Anthropology in Leipzig may have found the cause behind this allergy of yours.

The researchers say this condition could be due to a DNA factor, resulting out of encounters more than 40,000 years ago between humans and their burly cousins, the Neanderthals, or their close relatives, the Denisovans. The gene may have left the present day humans more susceptible to sneezes, itches and other forms of allergies.

Through recent studies, many groups of scientists had been trying to figure out what impact that Neanderthal DNA factor could have on modern humans.

Scientists from Newcastle University in the United Kingdom have gone ahead and proved that praying mantises have 3D vision, which is known as strereopsis. The researchers developed tiny e3D glasses for the bugs and made them wear it. It is an important discovery since until now, 3D vision had only been proved for vertebrates. The journal Scientific Results published the outcomes provided by the team.

Astronomers have combined the age data that they gathered by studying 70,000 stars across the Milky Way galaxy. The outcome of the ages of stars was assembled into the largest ever made galactic map.

Subsequently, the galactic map validated what has been considered the growth path of our galaxy, it commenced in from the mid of the galaxy and moved outwards. The trend was evident in several old stars that were found close to the centre of the disc.
