Though researchers are still stumped as to what caused the repeated eruptions, they hope the observations will help them get closer to an answer. The entity in question is called a fast radio burst (FRB), an enigmatic phenomenon first observed in 2007. FRBs produce pulses in the radio part of the electromagnetic spectrum; these pulses last only a few thousandths of a second but produce as much energy as the sun does in a year.

When the body was first discovered around 2010, above an ancient tomb that was built 700 years before he was killed, scientists wondered whether the victim was a grave-robber who had died while attempting to raid the tomb. But a new study reveals he was likely murdered, and whoever murdered the man seems to have hidden his remains in a looters' shaft above the tomb in an attempt to conceal the crime.

Inscriptions found in the tomb say that Ptah-M-Wia, the person buried there, held a number of positions including head of the treasury and chief supervisor of livestock during the reign of pharaoh Ramesses II (reign 1279–1213 B.C.), who expanded Egypt's empire as far as modern-day Syria. Ramesses II was also known for his building endeavors including the expansion of Karnak Temple, archaeologists said in a statement from the Egyptian ministry. Ptah-M-Wia was head of the treasury centuries before the invention of minted coins; at that time people made payments with goods, rations or precious metals.

China's Chang'e 5 spacecraft collected 3.81 pounds (1.73 kilograms) of lunar dust and rocks from a region called Oceanus Procellarum on the near side of the moon in December 2020. The mission team targeted this landing area because of its apparent lower density of craters, suggesting it was significantly younger than areas sampled by the Apollo and Soviet Luna missions.

Here's why you should still get it.]( (Jose Luis Pelaez/Corbis/VCG via Getty Images) Health officials recommend that everyone 6 months and older, with a few exceptions, get a flu shot each year. Yet, the flu vaccine is far from foolproof, according to the Centers for Disease Control and Prevention (CDC). If that's the case, why should you get it? On average, people who get the flu shot are between 40% and 60% less likely to catch the virus than unvaccinated individuals. So, although the flu shot may not prevent all cases of influenza, it helps protect you from severe infection and death and can help reduce the spread of the virus in communities.

Polletta, M. et al. 2021; Koyama, Y. et al. 2021) Astronomers have discovered a massive "shipyard" where galaxies are built, similar to the one our Milky Way grew up in. The giant structure, called a protocluster, contains more than 60 galaxies and is 11 billion light-years from Earth, so far away that scientists are observing a part of the universe that is only 3 billion years old. Researchers released a paper on the protocluster named G237 in January, but its existence has now been confirmed by an international team of astronomers, who published their follow-up findings on Oct. 26 in the journal Astronomy & Astrophysics.
