Scientists modified the existing SIR class pandemic prediction model. The model becomes more accurate, as the reduction of individuals in contact during the pandemic is objectively present in society. Moreover, the modification creates the possibility for scenario modelling.

According to Childs' team's study, while a mosquito ingests the parasite in a "blood meal" by biting an infected person, it typically takes about 10 to 14 days -- known as the "extrinsic incubation period" or EIP -- until the parasites appear in the mosquito's salivary glands where it can then be transmitted to another human.

Astronomers have tested a method for reconstructing the state of the early Universe by applying it to 4000 simulated universes using the ATERUI II supercomputer at the National Astronomical Observatory of Japan (NAOJ). They found that together with new observations the method can set better constraints on inflation, one of the most enigmatic events in the history of the Universe. The method can shorten the observation time required to distinguish between various inflation theories.

A research professor gives a "shout out" to comedian Stephen Colbert. His motivation? Colbert previously referred to mathematical equations as the devil's sentences and an unnatural commingling of letters and numbers - the worst being the quadratic equation - an infernal salad of numbers, letters and symbols. In response, the professor suggests that mathematics education needs to be enlivened so that students will recognize that this discipline is not merely a necessary evil, but a vibrant, exciting and fascinating subject.

Researchers from Skoltech have surveyed the newest known 30-meter deep gas blowout crater on the Yamal Peninsula, which formed in the summer of 2020. They piloted the drone used for crater surveillance; that was the first time a drone flew inside the crater for "underground aerial survey" 10 to 15 meters below ground, running the risk of losing the aircraft.
