We now know what history going up in flames looks like.
On Sept. 2, the National Museum of Brazil lit up Rio de Janeiro’s night sky. Perhaps started by an errant paper hot air balloon landing on the roof or a short circuit in a laboratory, the fire gutted the historic 200-year-old building. Likely ...read more

One of the long-standing problems in astronomy is that you cannot hold the Sun. You can’t jump into it or examine it under a microscope. Nor can astronomers go back in time to witness the Big Bang or even ...read more

A bold or aggressive person can change the dynamic of a group. That happens in spider colonies, too.
In a study published this week in Proceedings of the Royal Society B, researchers show that bold spiders can change the behavior of other spiders. The meek spiders start copying the behavior, something that can both help and potentially harm the colony.

Robat can’t fly. But the autonomous robot can use echolocation to survey its environment. (Robat is a fully-autonomous bat-like terrestrial robot that uses echolocation to navigate its environment. (Credit: Itamar Eliakim)
Bats can fly nimbly at night in large part because echolocation helps them “see” in the dark. Now researchers say they have created the first robot to use echolocation like a bat to help it explore its surroundings fully autonomously.

The years following the Big Bang were undoubtedly an exciting time in our cosmological history, with galaxies birthing hundreds or even thousands of hot new stars each year. But despite rapid star formation being exhilarating, it’s far from sustainable.

Adding wind and solar energy farms in Africa – and elsewhere – could bring increased rainfall, according to a new study. (Credit: Nebojsa Markovic/shutterstock)
Scientists want to power the world with solar and wind energy, a feat they say is possible with large-scale wind and solar farms. Now, an international team of researchers says that building such an energy factory in the Sahara desert would come with a surprising boon: more rainfall.
The discovery means feeding the global p ...read more

There was, at one point, a backup shuttle prepared. When the space shuttle Atlantis was launched for the STS-125 mission to service the Hubble Space Telescope, the Endeavour was also ready as a backup in case something went wrong and the crew of the Atlantis needed to ...read more
Valentin Bondarenko, the burned man doctors thought was a killed cosmonaut. via Astronautix.
There’s an ongoing fascination with the idea of phantom cosmonauts. The story goes something like this: a handful of Soviets launched into space before Yuri Gagarin orbited the Earth, but because they all died their missions and deaths were covered up. The stories are myth. No one flew in space before Gagarin. Even X-15 flights above the Karman line came after 1962. But like any enduring myth, the ...read more

This story originally appeared in bioGraphic.
On a humid May afternoon beneath the shade cloth of the plant nursery on his South Texas ranch, Benito Treviño leaned down, magnifying glasses perched on his nose above an extravagant salt-and-pepper moustache, and used his pen knife to remove a bulbous growth from the top of a baseball-sized, dome-shaped ...read more

As the crisis of antibiotic resistance deepens, researchers are looking for new ways to combat infectious diseases. One solution proposed by UCLA researchers: When one drug won’t work, try two. Or three, four or five.
Seeing What Sticks
In a new paper in Nature Systems Biology and Applications, scientists take a look at eight common antibiotics and run through thousands of combinations involving anywhere from two to five of them. They uncovered numerous com ...read more
