Proteins’ amino-acid sequences appear to guide their access to blob-like aggregates involved in many cell processes.

The surface of the Earth’s inner core may be changing, as shown by a new study by USC scientists that detected structural changes near the planet’s center, published in Nature Geoscience.
The changes of the inner core have long been a topic of debate for scientists. However, most research has been focused on assessing rotation. John Vidale, Dean’s Professor of Earth Sciences at the USC Dornsife College of Letters, Arts and Sciences and principal investigator of the study, said the researchers “didn’t set out to define the physical nature of the inner core.”
“What we ended up discovering is evidence that the near surface of Earth’s inner core undergoes structural change,” Vidale said. The finding sheds light on the role topographical activity plays in rotational changes in the inner core that have minutely altered the length of a day and may relate to the ongoing slowing of the inner core.
“Kara”, Quantic Dream’s newest tech demo featuring the early 2011 version of our new PS3 engine.
Valorie Curry’s acting was performance captured (body, face, voice) on December 14. 2010 in our then newly renovated motion capture studio, using a 64 high-precision Vicon camera system. This is a compressed (QT.H264 720 p) video capture of the realtime running demo on PS3. A making-of will follow soon. KARA is NOT Quantic Dream’s upcoming PS3 title. The later shall be revealed soon.
Summary: New research reveals that serotonin in the cerebellum plays a crucial role in anxiety regulation. Scientists found that mice with lower cerebellar serotonin levels displayed increased anxiety-like behaviors, while those with higher serotonin levels were less anxious.
By artificially stimulating or inhibiting serotonin-releasing neurons in the cerebellum, researchers were able to bidirectionally control anxiety responses. This challenges previous assumptions that serotonin universally increases anxiety and highlights the cerebellum as a key player in emotional regulation.
The findings provide a potential pathway for developing more precise treatments for anxiety disorders. Future research may explore whether this mechanism operates similarly in humans and how it can be therapeutically targeted.
When you think of a mushroom—whether psilocybin or portobello—you probably envision a stem and cap common for this type of fungi. The new Snowball mushroom is anything but typical.
This particular strain of “magic mushroom” is aptly named, as it resembles dozens of snowballs packed together. Mycologist Pope Joseph painstakingly coaxed a mutation from another mushroom species into creating the look he wanted, says Drew Collins, founder and CEO of InoculateTheWorld (ITW). His company distributes mushroom spores and introduced the Snowball mushroom to the world.
The Snowball is a significant development in growing mushrooms that have psilocybin, a compound that causes psychedelic effects, such as visual and auditory hallucinations. This form is unlike anything that’s ever been seen in mushroom cultivation before, Collins says. “I’ve been describing it as that moment you look out the window of a plane and there’s a never ending field of clouds.”
Psychologists call it the dark triad: an intersection of three of the most malevolent tendencies of human nature – psychopathy, narcissism, and Machiavellianism.
But the truth goes deeper, and darker. There’s also egoism, sadism, spitefulness, and more. And behind this rogues gallery of all our worst inclinations on the surface, a central, common core of human darkness lies, researchers say.
In a 2018 study, psychologists from Germany and Denmark mapped this driving force behind all our darkest impulses and gave it a name. Meet D, the newly identified Dark Factor of Personality.
Tesla’s first four-hour Megapack project in the Netherlands has gone online, coming as the latest of the company’s energy storage deployments.
Precisely controlling sparks allows for their use in a wide variety of applications.
For the first time, scientists have found that electric sparks can be guided using ultrasonic waves. A recent study by researchers from Spain, Finland, and Canada uncovered the way in which ultrasonic waves transport electricity through air.
Researchers revealed that this guidance occurs because the sparks heat up the air, which expands and lowers its density.
The hot air is then guided by ultrasonic waves into regions where the sound intensity is higher, and the next sparks follow these regions of lighter air because of its lower breakdown voltage, according to researchers.
The enzyme PKMzeta is crucial for the maintenance of long-term memories, but a closely related enzyme provides a back-up should PKMzeta fail, thus explaining the controversy over why deleting the gene for PKMzeta may not appear to impair memory.
