A Person’s Intelligence Limits their Computer Proficiency More than Previously Thought, say Researchers

Posted by in categories: computing, neuroscience

A new study has found that intelligence, in the form of general cognitive abilities such as perception, thinking and remembering, is more important than hitherto thought at predicting a person’s ability to complete common tasks with a PC. The study was published in the International Journal of Human-Computer Studies in August 2024.

“Our research findings are the first clear proof that cognitive abilities have a significant, independent and wide-ranging effect on people’s ability to use a computer. Contrary to what was previously thought, cognitive abilities are as important as previous experience of computer use,” says Aalto University’s Professor Antti Oulasvirta, who studied human-computer interaction extensively with his team.

The findings have implications for digital equality, say the researchers, because everyday user interfaces have simply become too complex to use. Practice alone is no longer enough, with intelligence becoming an equally critical factor in predicting performance in computer tasks.

Cosmology Is at a Tipping Point—We May Be on the Verge of Discovering New Physics

Posted by in categories: cosmology, evolution, particle physics

For the past few years, a series of controversies have rocked the well-established field of cosmology. In a nutshell, the predictions of the standard model of the universe appear to be at odds with some recent observations.

There are heated debates about whether these observations are biased, or whether the cosmological model, which predicts the structure and evolution of the entire universe, may need a rethink. Some even claim that cosmology is in crisis. Right now, we do not know which side will win. But excitingly, we are on the brink of finding that out.

A dual-species Rydberg array

Posted by in categories: computing, particle physics, quantum physics

In quantum computing, scientists often work with arrays of atoms called Rydberg atom arrays, which allow them to simulate quantum systems and perform computations.


Rydberg atoms in optical tweezers are a promising platform for quantum information science. A platform composed of dual-species Rydberg arrays has been realized, offering access to unexplored interaction regimes and crosstalk-free midcircuit control.

Q&A: Scientist discusses the MESSENGER mission to Mercury by Carnegie Institution for Science

Posted by in categories: science, space

Twenty years ago, the MESSENGER mission revolutionized our understanding of Mercury. We sat down with project head and former Carnegie Science director Sean Solomon to talk about how the mission came together and the groundbreaking work it enabled.

Q: As the principal investigator of the MESSENGER mission, what were your personal highlights or proudest moments throughout the mission’s duration? Sean Solomon: There were many personal highlights for me during the MESSENGER mission, beginning with our initial selection by NASA in 1999 and culminating in the publication by the MESSENGER science team of all of the findings from our mission in a book published nearly two decades later.

The most challenging events in any planetary orbiter mission are launch and orbit insertion. The successful completion of those two milestones for MESSENGER—in 2004 and 2011, respectively—were sources of great pride for me in the technical expertise of all of the engineers, mission design experts, and project managers who contributed to the mission.

Thermal effects in spintronics systematically assessed for first time

Posted by in categories: computing, particle physics

Spintronics—devices that use microscopic magnetism in conjunction with electric current—could lead to computing technology as fast as conventional electronics but much more energy efficient. As such devices are developed and studied, an important unresolved question is how device operation is affected by heating.

New insights into hot carrier solar cells: Study explores hot electron tunneling and collection to enhance efficiency

Posted by in categories: solar power, sustainability

Hot carrier solar cells, a concept introduced several decades ago, have long been seen as a potential breakthrough in solar energy technology. These cells could surpass the Shockley–Queisser efficiency limit, which is a theoretical maximum efficiency for single-junction solar cells. Despite their promise, practical implementation has faced significant challenges, particularly in managing the rapid extraction of hot electrons across material interfaces.
