Dark matter was likely the starting ingredient for brewing up the very first galaxies in the universe. Shortly after the Big Bang, particles of dark matter would have clumped together in gravitational “halos,” pulling surrounding gas into their cores, which over time cooled and condensed into the first galaxies.

Although dark matter is considered the backbone to the structure of the universe, scientists know very little about its nature, as the particles have so far evaded detection.

Now scientists at MIT, Princeton University, and Cambridge University have found that the early universe, and the very first galaxies, would have looked very different depending on the nature of dark matter. For the first time, the team has simulated what early galaxy formation would have looked like if dark matter were “fuzzy,” rather than cold or warm.

At SynBioBeta, entrepreneurs making plant-based foods and genetically engineered bacteria rallied to promote the idea that it’s biology’s century.

After counting all the normal, luminous matter in the obvious places of the universe – galaxies, clusters of galaxies and the intergalactic medium – about half of it is still missing. So not only is 85 percent of the matter in the universe made up of an unknown, invisible substance dubbed “dark matter”, we can’t even find all the small amount of normal matter that should be there.

This is known as the “missing baryons” problem. Baryons are particles that emit or absorb light, like protons, neutrons or electrons, which make up the matter we see around us. The baryons unaccounted for are thought to be hidden in filamentary structures permeating the entire universe, also known as “the cosmic web”.

L AS VEGAS — At a biohacker conference convened here the other day, panelists took to the stage, settled into their chairs, and launched into their slide decks. Not Anastasia Synn.

With Frank Sinatra crooning “I’ve Got You Under My Skin” over the loudspeakers, Synn pulled out a giant needle and twisted it deeper and deeper into her left forearm as the music played on. It was only after finishing her routine, capped off by loud applause from the crowd of biohackers, that Synn sat down for a fireside chat about her work as a “cyborg magician.”

Steve Mann invented a precursor to Google Glass in the 1990s—which he now uses almost 24/7. But “the father of wearable computing” has an ominous warning about where technology is taking us next.

Cadmium nuclei take on multiple shapes at low excitation energies, a discovery that overturns a long-accepted tenet of nuclear structure.

Atomic nuclei take on excited states when they vibrate, rotate, or when their constituent nucleons exchange one nuclear shell for another. In nuclei with nearly filled nuclear shells, it has long been thought that low-energy excitations were due exclusively to different patterns of vibration around a spherical shape: only in rare, high-energy excitations were these nuclei expected to assume more exotic shapes. Now, Paul Garrett, of the University of Guelph in Canada, and colleagues have found that the lowest-energy excited states of cadmium-110 and cadmium-112—once considered textbook examples of spherical vibration—are instead due to the rotation of various nonspherical shapes. The result is also the best evidence to date that a stable nucleus like cadmium can assume multiple shapes—all previously studied nuclei with coexisting shapes have been radioactive.

Following Elon Musk’s presentation about SpaceX’s Starship rocket, the company posted a 2-minute video showing how it’d refill the system in orbit.

NASA’s InSight lander has picked up on some interesting rumblings on Mars, and the space agency shared them Tuesday in a blog post.

The spacecraft is equipped with an incredibly sensitive seismometer called the Seismic Experiment for Interior Structure (SEIS), which is designed to listen for marsquakes. By examining how seismic waves move through the planet’s interior, scientists hope to learn more about Mars’ deep inner structure.

A SCIENTIST revealed how NASA has a last-ditch system in place in the event a huge space rock is “due to impact Earth in one to three weeks” during a planet-saving warning.
