Physicists explain mysterious dark matter deficiency in galaxy pair Posted: 09 Sep 2020 10:21 AM PDT A new theory about the nature of dark matter helps explain why a pair of galaxies about 65 million light-years from Earth contains very little of the mysterious matter.

Physicists use classical concepts to decipher strange quantum behaviors in an ultracold gas Posted: 09 Sep 2020 10:20 AM PDT There they were, in all their weird quantum glory: ultracold lithium atoms in the optical trap. Held by lasers in a regular, lattice formation and 'driven' by pulses of energy, these atoms were doing crazy things.

AI used to show how hydrogen becomes a metal inside giant planets Posted: 09 Sep 2020 08:48 AM PDT Researchers have used a combination of AI and quantum mechanics to reveal how hydrogen gradually turns into a metal inside giant planets.

Massive halo finally explains stream of gas swirling around the Milky Way Posted: 09 Sep 2020 08:48 AM PDT Astronomers have discovered that a halo of warm gas surrounding the Magellanic Clouds likely acts as a protective cocoon, shielding the dwarf galaxies from the Milky Way's own halo and contributing most of the Magellanic Stream's mass.

More cats might be COVID-19 positive than first believed, study suggests Posted: 09 Sep 2020 08:48 AM PDT A newly published study looking at cats in Wuhan, where the first known outbreak of COVID-19 began, shows more cats might be contracting the disease than first believed.

Sand-sized meteoroids are peppering asteroid Bennu Posted: 09 Sep 2020 08:48 AM PDT A new study posits that the major particle ejections off the near-Earth asteroid Bennu may be the consequence of impacts by small, sand-sized particles called meteoroids onto its surface as the object nears the Sun.

Tool transforms world landmark photos into 4D experiences Posted: 09 Sep 2020 07:02 AM PDT Using publicly available tourist photos of world landmarks such as the Trevi Fountain in Rome or Top of the Rock in New York City, researchers have developed a method to create maneuverable 3D images that show changes in appearance over time.

New glove-like device mimics sense of touch Posted: 09 Sep 2020 07:02 AM PDT Engineers have invented a soft wearable device which simulates the sense of touch and has wide potential for medical, industrial and entertainment applications.

Australian telescope finds no signs of alien technology in 10 million star systems Posted: 09 Sep 2020 05:59 AM PDT A radio telescope in outback Western Australia has completed the deepest and broadest search at low frequencies for alien technologies, scanning a patch of sky known to include at least 10 million stars. Astronomers used the Murchison Widefield Array (MWA) telescope to explore hundreds of times more broadly than any previous search for extraterrestrial life.

Painting with light: Novel nanopillars precisely control intensity of transmitted light Posted: 04 Sep 2020 01:33 PM PDT By shining white light on a glass slide stippled with millions of tiny titanium dioxide pillars, researchers have reproduced with astonishing fidelity the luminous hues and subtle shadings of 'Girl With a Pearl Earring.'

Repulsion mechanism between neurons governs fly brain structure Posted: 04 Sep 2020 07:06 AM PDT Researchers have discovered that in the developing fly brain, neurons stemming from the same parent cell experience repulsion. This lineage-dependent repulsion is regulated by a protein known as Dscam1.

Fatty acid receptor involved in temperature-induced sex reversal of Japanese medaka fish Posted: 04 Sep 2020 07:06 AM PDT Researchers have found that activation of a fatty acid receptor that detects fatty acids in cells and regulates physiological functions causes Japanese rice fish (medaka) to become male. The discovery of this molecular mechanism is expected to advance the development of new sex control technologies.

Do big tadpoles turn into big frogs? It's complicated Posted: 04 Sep 2020 06:29 AM PDT Researchers studied the evolution of the body sizes of frogs and their tadpoles. They found that the two life stages do not evolve completely independently of each other as previously thought.
