Imagine the possibility of sending messages that are completely impervious to even the most powerful computers. This is the incredible promise of quantum communication, which harnesses the unique properties of light particles known as photons.
Today’s supercomputers consume vast amounts of energy, equivalent to the power usage of thousands of homes. In response, researchers are developing a more energy-efficient form of next-generation supercomputing that leverages artificial neural networks.
Checking whether an avocado is hard or soft by looking at it? This would require recognizing how the plant cells behave behind the skin. The same applies to all other cells on our planet: Despite more than 100 years of intensive research, many of their properties remain hidden inside the cell.
For the first time, astronomers have captured an image of a neutron star emitting a ‘garden sprinkler-like’ S-shaped jet in the binary system Circinus X-1, located over 30,000 light-years away.
This phenomenon, similar to precession observed in black holes, illustrates the jet’s direction change due to the gravitational pull from a disc of hot gas. The discovery was made using the MeerKAT radio telescope, and the findings provide insights into the dynamics of neutron stars and the mechanics of jet launching.

Laser pulses have been shown to adjust the magnetic properties of rare earths by affecting 4f electrons, opening avenues for quicker and more energy-efficient data storage devices.
The special properties of rare earth magnetic materials are due to the electrons in the 4f shell. Until now, the magnetic properties of 4f electrons were considered almost impossible to control. Now, scientists have shown for the first time that laser pulses can influence 4f electrons — and thus change their magnetic properties. The discovery, which was made through experiments at EuXFEL and FLASH, opens up a new way to data storage with rare earth elements.
Breakthrough in Magnetic Properties Control.
Mental effort is generally unpleasant, as confirmed by a meta-analysis involving over 4,600 participants across various tasks and demographics. People often pursue challenging activities for the rewards, not the pleasure of the task. Credit: SciTechDaily.com.
A meta-analysis of 170 studies revealed that regardless of the task or population, increased mental effort correlates with feelings of frustration and stress. This phenomenon is less pronounced in Asian populations, possibly due to different educational experiences. Despite this, people still engage in mentally challenging tasks like chess, driven by the rewards rather than enjoyment of the effort itself.
A new robot bug that can live in the ocean for 100 years and feed off of bacteria has made its debut as DARPA’s latest surveillance tool.
With a vast amount of area to cover, the US government is funding research for new oceanic spy technology. Now, a Binghamton University team has developed what may become one of the most simple and effective tools in its arsenal.
Now, a new DARPA initiative is playing off of the idea of “the Internet of Things,” the term used for the many non-computer devices connected to the Internet in some way, from refrigerators to fish tanks, and seeking to develop an “Ocean of Things.” With many futurists’ eyes on space conflict and satellite warfare, it’s easy to forget that 71% of the Earth’s surface is water, and naval conflict is still an element in geopolitics.
