Researchers at MIT are using AI to train AI not to give toxic responses, using a new method that replicates human curiosity.

NASA's Voyager 1 probe has resumed sending usable data back to Earth after engineers fixed a computer error that caused the interstellar spacecraft to only transmit gibberish for five months.

Enslaved people picked the cherries around 250 years ago, likely in pre-Revolutionary War times.

Researchers developed an innovative chemical tool to explore how signals like dopamine and epinephrine interact with neurons via G protein-coupled receptors (GPCRs). This new tool allows for precise detection of neuromod...

Climate change's effects on ocean water temperatures and salinity could shrink sonar detection ranges underwater and make it more challenging to spot submarines

The chest could help archaeologists understand the fire and explosion that sank the vessel.

A new research study from Opto-Electronic Advances discusses tailoring electron vortex beams with customizable intensity patterns by electron diffraction holography.

It's the most fundamental of processes--the evaporation of water from the surfaces of oceans and lakes, the burning off of fog in the morning sun, and the drying of briny ponds that leaves solid salt behind. Evaporation ...

A new study explores how different light levels impact cognitive function by influencing hypothalamic activity in the brain. The study utilized advanced 7 Tesla fMRI to show that higher levels of light improve cognitive ...

Neurons in Alzheimer's disease patients tend to re-enter the cell cycle and quickly progress to senescence. Using advanced snRNA-seq techniques, researchers analyzed over 30,000 nuclei to track these changes, finding tha...

An explosive flare from the Milky Way's central black hole has been translated from 'a single flickering pixel' into a detailed 3D model using AI and Einstein's general relativity equations.

A new study highlights the critical role of beta rhythms (14-30 Hz) in orchestrating cognitive processes. The research synthesizes experimental data and theoretical models to show that bursts of beta rhythms facilitate c...

Individuals with weak social ties exhibit more synchronized brain activity during cooperative tasks than those with strong ties. Researchers challenged the traditional view that stronger social connections lead to greate...

Spintronics is a field garnering immense attention for its range of potential advantages for conventional electronics. These include reducing power consumption, high-speed operation, non-volatility, and the potential for...

A new study explores how human behaviors spread through social networks, revealing that long ties--connections that bridge distant parts of a network--significantly accelerate the adoption of new behaviors and ideas. Con...

For over a decade, the CMS Collaboration, a large team of researchers based at different institutes worldwide, has been analyzing data collected at the Compact Muon Solenoid, a general-purpose particle detector at CERN's...

By modifying a refrigerator commonly used in both research and industry, researchers at the National Institute of Standards and Technology (NIST) have drastically reduced the time and energy required to cool materials to...

The U.S. nuclear physics community is preparing to build the electron-ion collider (EIC), a flagship facility for probing the properties of matter and the strong nuclear force that holds matter together. The EIC will all...

Amazon says it will create new jobs to replace roles taken over by machines, but it isn't clear whether this will happen quickly enough

The balance of omega fatty acids in the food we eat affects our health. But what does the evidence say about claims you should be seeking to reduce omega-6 intake as well as boosting omega-3s?

On April 10, a bright red atmospheric "hole" was spotted in the night sky above Texas shortly after SpaceX launched 23 Starlink satellites into space. It is the latest example of an increasingly common phenomenon caused ...

AI can analyse satellite images to reveal the movements of dark ships in a shadow fleet that smuggles oil and other cargo from sanctioned countries such as Russia, Iran, Venezuela and North Korea
