Neural Flexibility: Prioritizing Memories to Guide Behavior

Posted by in category: neuroscience

Summary: Male worms can activate two conflicting memories—mating and starvation—when encountering the same odor, but only one influences their behavior. A study conditioned worms to associate the smell with both positive (mating) and negative (starvation) experiences, revealing that mating associations overrode avoidance behavior.

This flexible memory processing highlights how the brain prioritizes rewards over punishment under certain conditions. The findings provide insights into memory-driven behavior and offer a model for studying maladaptive processes in disorders like PTSD.

Neurotransmitter switching in early development predicts autism-related behaviors

Posted by in categories: chemistry, neuroscience

Scientists have found that a process called neurotransmitter switching—where neurons alter their chemical signals—plays a role in the development of autism-related traits.

China’s new microwave weapon can fry enemy drones 2 miles away

Posted by in categories: drones, energy, military

China’s latest weapon, unveiled during an air show in Zhuhai, could be a game-changer during possible future conflicts with rival powers.


China is making advancements in its multiple military-related technologies that will give it an edge over its adversaries during a possible conflict in the future. During a recent giant air show in Zhuhai, Beijing unveiled multiple game-changer military technologies, including a mobile air defense weapons system.

Called FK-4000, the mobile air defense weapons system is reportedly capable of intercepting the smallest, lightest drones using its high-power microwaves (HPM).

Engineers create self-healing coating to cut sewer clogging by 30%

Posted by in category: materials

Fatbergs threaten sewers, but RMIT engineers have created a protective concrete coating to tackle the issue.


This results in severe sewer blockages, with data indicating that half of all blockages occur in the United States and 40% in Australia.

Our Universe Is A Bubble Universe That Exists Inside Of A Black Hole

Posted by in categories: cosmology, quantum physics

What if our universe is not the only one? What if it is just a tiny bubble inside a much larger and more complex reality? This is the idea behind the bubble universe theory, which suggests that our universe is one of many possible universes that exist inside a black hole.

What is a bubble universe?

A bubble universe is a hypothetical region of space that has different physical laws and constants than the rest of the multiverse. The multiverse is the collection of all possible universes that exist or could exist. A bubble universe could form when a quantum fluctuation creates a tiny pocket of space with different properties than its surroundings. This pocket could then expand and inflate into a large and isolated universe, like a bubble in a glass of water.

Altering two genes to produce sweeter tomatoes without sacrificing size, weight or yield

Posted by in category: food

A team of horticulturists, bio-breeders and agriculture specialists affiliated with a host of institutions across China has produced sweeter tomatoes without sacrificing size, weight or yield by altering two of their genes. In their study, published in the journal Nature, the group modified the genes of a tomato variant that coded for proteins that lowered levels of enzymes related to sugar production.

Encounter blew away most of smaller galaxy’s gaseous halo

Posted by in category: space

In an epic story of survival witnessed by the NASA/ESA Hubble Space Telescope, one of our nearest galactic neighbours has crashed through the Milky Way galaxy’s gaseous halo and lived to tell the tale. But in the process, this dwarf galaxy, called the Large Magellanic Cloud (LMC), has been stripped of most of its own surrounding halo of gas. Researchers were surprised to find such an extremely small gaseous halo remaining — one around 10 times smaller than halos of other galaxies of similar mass. Still, the LMC has held onto enough of its gas to keep forming new stars. A smaller galaxy wouldn’t have survived such an encounter. This is the first time astronomers have been able to measure the size of the LMC’s halo — something they could do only with Hubble.

The Large Magellanic Cloud, also called the LMC, is one of the Milky Way galaxy’s nearest neighbours. This dwarf galaxy looms large in the southern nighttime sky at 20 times the apparent diameter of the full Moon.

Many researchers theorise that the LMC is not in orbit around our galaxy, but is just passing by. Those scientists think that the LMC has just completed its closest approach to the much more massive Milky Way. This passage has blown away most of the spherical halo of gas that surrounds the LMC.
