A team of researchers from British universities has trained a deep learning model that can steal data from keyboard keystrokes recorded using a microphone with an accuracy of 95%.

When Zoom was used for training the sound classification algorithm, the prediction accuracy dropped to 93%, which is still dangerously high, and a record for that medium.

Such an attack severely affects the target’s data security, as it could leak people’s passwords, discussions, messages, or other sensitive information to malicious third parties.

India’s third moon mission’s spacecraft, Chandrayaan-3, is one step closer to a lunar landing after the Indian Space Research Organisation (ISRO), announced that it has successfully entered the moon’s orbit, on Saturday (August 5).

ISRO’s Chandrayaan-3 mission update.

The announcement was made by the Indian space agency on X, formerly known as Twitter where it wrote: “‘MOX, ISTRAC, this is Chandrayaan-3. I am feeling lunar gravity’. Chandrayaan-3 has been successfully inserted into the lunar orbit.”

“Fake Drake” and similar controversies have gotten most of the attention, but not all uses of artificial intelligence in music are cause for concern.

Turtles migrate thousands of miles out in the open ocean, charting epic courses in search of food, mates, and nesting grounds. Exactly how they find where they’re going has long puzzled scientists who suspected magnetic fields were involved, but were unsure of the exact mechanism through which turtles were sensing it.

We’ve since learned that turtles appear to recognize magnetic signatures of locations, such as the beach on which they hatched where females will later return to lay their own eggs. We know the magnetosphere is in constant flux, and turtle nesting sites have been found to shift in tandem, so how is it that they’re able to make sense of this invisible force?

Some answers to this question were revealed in a study that looked at the way snapping turtles can tell north from south, in a phenomenon known as spontaneous magnetic alignment. It was once thought to be a rare trait in the animal kingdom, but as Professor John Phillips from the Department of Biological Sciences at Virginia Tech told IFLScience, this is no longer the case.

Bacterial cells can easily share genes with one another, and have a few ways to do so. Viruses called bacteriophages infect bacterial cells, and they can also transfer genes between bacterial cells in a process known as transduction. Often, the genes that are being shared confer resistance to a drug, and once a bacterial cell gains the ability, antibiotic resistance can easily spread through populations of microbial cells. Now scientists have discovered another mechanism that bacteria use to share genes, and it can help microbes evolve even faster than we knew. The findings have been reported in Cell.

There are three types of transduction that we now know about: generalized, specialized, and lateral. The newly revealed mechanism is called lateral cotransduction. It is about as rapid as lateral transduction, which itself is far faster than generalized transduction. However, the study indicated that lateral cotransduction is more complex and versatile than the other modes of transduction. Lateral transduction happens when phages that have integrated into bacterial genomes are reactivated, and trigger reproduction in the lytic cycle; but lateral cotransduction can while new bacterial cells are being infected, and during the reactivation process.

Dopamine is a type of neurotransmitter that can provide an intense feeling of reward. It has been a long-standing assumption that most, if not all, dopamine neurons solely respond to rewards or reward-predicting cues. However, a study in mice led by researchers at Northwestern University reveals dopamine may also control movements. The researchers uncovered that one genetic subtype fires when the body moves and that these neurons do not respond to rewards at all.

The findings are published in Nature Neuroscience in an article titled, “Unique functional responses differentially map onto genetic subtypes of dopamine neurons,” and shed new light on the brain which may lead to new research on Parkinson’s disease, which is characterized by the loss of dopamine neurons yet affects the motor system.

“Dopamine neurons are characterized by their response to unexpected rewards, but they also fire during movement and aversive stimuli,” the researchers wrote. “Dopamine neuron diversity has been observed based on molecular expression profiles; however, whether different functions map onto such genetic subtypes remains unclear. In this study, we established that three genetic dopamine subtypes within the substantia nigra pars compacta, characterized by the expression of Slc17a6 (Vglut2), Calb1, and Anxa1, each have a unique set of responses to rewards, aversive stimuli, and accelerations and decelerations, and these signaling patterns are highly correlated between somas and axons within subtypes.”

The device was equipped with infrared technology.

A police drone equipped with infrared capabilities has risen as a hero in the search for a missing person with dementia that disappeared from a Delta hospital on July 29. Delta is a city located in British Columbia, Canada.

This is according to a report by Global News published on Wednesday.

It reduces water wastage and carbon emissions.

“When it comes to photovoltaics, dust is the enemy. This is not a trivial concept, even if it may seem so at first glance; actually, the problem of soiling – the accumulation of dust, dirt or sand on PV panels – can decrease, sometimes significantly, the performance of solar power systems,” stated an Enel Green Power press release published on Friday.
