Experiments have shown how the world’s hardiest microbe could endure freezing, dry and irradiated conditions on Mars.
The world wide web is not enough, because scientists have managed to transmit data at a staggering 1.84 petabits per second — nearly twice the amount of global internet traffic in the same interval.
That blows the previous record for data transmission using a single light source and optical chip of one petabit per second out the water. And to put that ridiculous amount into perspective, a petabit is equal to one million gigabits. A single gigabit, or 1,000 megabits, is about the fastest download speed money can buy for most households.
To achieve the astonishing feat, researchers from the Technical University of Denmark (DTU) and Chalmers University of Technology used a custom optical chip that can make use of a single infrared light by splitting it into hundreds of different frequencies that are evenly spaced apart. Collectively, they’re known as a frequency comb. Each frequency on the comb can discretely hold data by modulating the wave properties of light, allowing scientists to transmit far more bits than conventional methods.
The large diversity of organic molecules detected on Mars is a hint that life once existed there, but where should we search?

Dr. Peter Fedichev, Ph.D. is the CEO of Gero (https://gero.ai/), a biotech company focused on hacking complex diseases, including aging, with AI for novel drug discovery, as well as digital biomarkers.
Gero’s models originate from the physics of complex dynamic systems, combining the potential of deep neural networks with the physical models to study dynamical processes and understand what drives diseases.

Oocytes prevent the production of reactive oxygen species by remodelling the mitochondrial electron transport chain through elimination of complex I, a strategy that enables their long-term viability.
Engineers at the SLAC National Accelerator Laboratory in California are putting the finishing touches on the world’s largest digital camera, which will be at the heart of the Vera C. Rubin Observatory.
Ultrasound sensors as small as a thumbnail can scan lithium-ion batteries to check their charge, health, and safety, a new study finds.
The findings suggest that ultrasound—that is, sound waves at frequencies higher than human hearing can detect—might one day help electric vehicles better estimate how much charge remains in their batteries. This approach might also help detect unstable batteries on the verge of disaster, quickly test battery quality during manufacturing, and identify which used batteries are healthy enough to be resold to reduce waste, says study lead author Hongbin Sun, an ultrasonic engineer at the Oak Ridge National Laboratory, in Tennessee.
Estimating how much charge is left in a commercial lithium-ion battery is currently a challenging task. For instance, electric vehicles typically experience an uncertainty of about 10 percent when estimating battery charge. This in turn reduces their driving range by about 10 percent, to ensure that they stay within their batteries’ safety margins.
Electric bees 🐝🌞
“When I looked at the data, I was kind of surprised to see that it had a massive effect,” says Hunting. It was already known that individual bees carry a small charge, but a voltage of this magnitude had never been documented in swarming honeybees before.
The team deployed additional electric field monitors in combination with video cameras to measure the electric field and swarm density, and waited for the bees at nearby hives to naturally swarm. The researchers recorded three swarms passing the monitors for around 3 minutes at a time. They found that the bee swarms created an electric charge ranging from 100 to 1,000 volts per metre. By analysing the proximity of bees to each other in the swarms, the team found that the denser the swarm, the stronger the electric field was.
