The mysterious zones have the power to slow down seismic waves by up to 50 per cent, yet experts don’t know what they’re made of or what role they play.

These strange black holes (figuratively speaking) are located within the Earth’s lower mantle – near the core – and are known as ultra-low velocity zones (ULVZs).

When neutron stars dance together, the grand smash finale they experience might create the densest known form of matter known in the Universe. It’s called “quark matter, ” a highly weird combo of liberated quarks and gluons. It’s unclear if the stuff existed in their cores before the end of their dance. However, in the wild aftermath a neutron-star merger, the strange conditions could free quarks and gluons from protons and neutrons. That lets them move around freely in the aftermath. So, researchers want to know how freely they move and what conditions might impede their motion (or flow).

The submerged Neolithic city most possibly belonged to the pre-historic remains of ancient Hvar civilization located in Croatia.

Instead of the single-use paper or plastic cups that Gearhard would usually line up for the barista slinging espresso, he’s passing over shiny new reusable cups that bear the slogan “Sip, Return, Repeat”. Customers who need their lattes to go can take the purple cups with them, then return them to one of 60 bins scattered across downtown Petaluma when they’ve finished. Each cup comes with a trackable QR code to help monitor results.

• Researchers have just found evidence of “dark electrons”—electrons you can’t see using spectroscopy—in solid materials.
• By analyzing the electrons in palladium diselenide, the team was able to find states that functionally cancel each other out, blocking the electrons in those “dark states” from view.
• The scientists believe this behavior is likely to be found across many other substances as well, and could help explain why some superconductors behave in unexpected ways.

Initially, THC boosted brain metabolism and synaptic protein levels, indicative of heightened cognitive processes. Subsequently, it shifted towards reducing metabolic activities in the body akin to the effects seen with caloric restriction or intensive exercise, known for their anti-aging benefits.

The American Veterinary Medical Association said symptoms to watch for include a staggering gait, the inability to retract claws, extreme sensitivity to touch, tremors, and seizures. The illness usually lasts for a few days to a few weeks, but can also linger for more than a year.

The researchers also say that current fire-resisting gels dry out and become useless about 45 minutes after being applied. With their new material however, because the silica aerogel stays behind until it is washed away, the coating could be applied well in advance of an approaching wildfire while still providing protection when the flames arrive

Their attosecond system involves a powerful laser split into two components: a fast electron pulse and two ultrashort light pulses. The first light pulse, called the pump pulse, energizes a sample, triggering electron movement or other rapid changes. The second pulse, known as the optical gating pulse, creates a brief window to generate a single attosecond electron pulse. The timing of this gating pulse determines the image resolution. By precisely synchronizing these pulses, researchers can control when the electron pulses probe the sample, allowing them to observe ultrafast atomic-level processes.
