Scientists think that nuanced hints called technosignatures could point them to life on other planets, including radio waves and pollution.
Kat DeLorean has built a new company to engineer the vehicle.
Kat DeLorean, daughter of legendary automotive engineer John DeLorean is building a new sports car to honor her father’s memory, according to a blog of the car’s site.

With an estimated 60 to 70 vessels, China allegedly possesses the largest fleet of conventional submarines in the world.
The Chinese Navy could finally use lithium technology to replace the lead-acid batteries that are now used in its fleet of conventional submarines.
Since lithium batteries had a higher risk of catching fire or exploding, the navy was hesitant to replace the submarine fleet’s current batteries with them.

Transitioning away from fossil fuels.
The cost of turning sunlight into electricity has fallen more than 90 percent over the last decade. Solar is now the cheapest form of newly built energy generation. Job done? Not quite. Right now, solar works well at cost-competitive prices and can help us cut emissions significantly. But with less than five percent of the world’s electricity delivered by solar, we are just at the start.
The solar panels of 2022 are like the chunky mobile phones of the 1990s. Much more is possible with the same underlying technology.
Australia is likely to play a key role in global progress.
Could we describe and search for proof of technology originating from outside of Earth?
If an alien were to look at Earth, many human technologies — from cell towers to fluorescent light bulbs — could be a beacon signifying the presence of life.
We are two astronomers who work on the search for extraterrestrial intelligence — or SETI. In our research, we try to characterize and detect signs of technology originating from beyond Earth. These are called technosignatures. While scanning the sky for a TV broadcast of some extraterrestrial Olympics may sound straightforward, searching for signs of distant, advanced civilizations is a much more nuanced and difficult task than it might seem. iStock.
Scientists and materials researchers have invented a new and improved tool, “lab on a chip,” to measure light, according to a press release by Oregon State University (OSU) published on October 20.
An ultra-tiny device
The new tool consists of an ultra-tiny spectrometer that fits on a microchip and is operated using artificial intelligence. It now may lead to upgrades in everything from smartphone cameras to environmental monitoring.
E-scooters are all the rage in Türkiye, as their sales and number of companies renting them soared in recent years. Yet, they have several cons, like long charging times and possible pollution from the uncontrolled disposal of discarded batteries. Four Turkish engineers hope a new scooter, working on hydrogen power, may overcome these problems.
“Hebunk,” devised by entrepreneurs working at a technology park at Istanbul Technical University, boasts a fast charging time, just five minutes, and can travel for 60 kilometers (37.28 miles) with a single charge, which roughly costs about 9 cents (TL 1.8).
The scooter, which is not too different from e-scooters in appearance, was developed in one year by the entrepreneurs’ HydroBorPEM Fuel Cell Technologies, now based at a technology park in Istanbul’s Yıldız Technical University.
Technology is advancing so rapidly that it’s almost impossible to keep up with the ever-changing landscape of innovation. That’s why we’ve compiled the 50 most insane new scientific discoveries of the last decade into one epic video!

To test the interaction between senolytic removal of senescent cells and cellular reprograming, we designed a model combining these two interventions in an inducible overexpression system in Drosophila. First, we used the four Yamanaka factor based OKSM approach as this had been previously shown to induce pluripotent stem cells in mice [7], humans [29 – 31] and non-mammalian vertebrate and invertebrate species [32]. To make a senolytic factor for Drosophila, we took advantage of the mouse sequence (FOXO4-DRI [22]) to design an orthologous peptide based on the Drosophila foxo (forkhead box, sub-group O) gene [33]. We then characterized effects of these two interventions independently as well as in combination.
We began by looking at the effect of OKSM and Sen on stem cells in an intestinal stem cell (ISC) model [34, 35]. We chose to investigate phenotypic effects specifically in the digestive system of Drosophila (Supplementary Figure 1). As in mammals, the Drosophila gastric lining has a high turnover of cells which is enabled by stem cell pools that replenish the epithelia [34]. Age-dependent loss of stem cells and degradation of barrier function has been shown to contribute to age-dependent functional decline and mortality in Drosophila [36]. The Drosophila gut is composed of four cell types: enterocytes (ECs or absorptive cells), enteroendocrine (EEs or secretory cells), enteroblasts (EBs or transit amplifying cells) and intestinal stem cells (ISCs).
