In recent years, scientists have learned that one of Earth’s most unique features — its liquid oceans — is far more common throughout the solar system than scientists ever expected.

Take Ceres, a dwarf planet orbiting our Sun inside the asteroid belt, which scientists discovered earlier this year is actually an ocean world, according to Discover Magazine. The discovery of abundant water on other worlds could have huge implications for the search for extraterrestrial life — to the point that NASA astronomer Alan Stern tells Discover that it’s “one of the most profound discoveries in planetary science in the Space Age.”

Australians are in awe of a native bee covered in deep blue stripes after learning the unusual insect can be found across the country.

The blue-banded bee can be spotted in gardens in each state except for Tasmania and can be recognised by the coloured stripes around their abdomen.

While the bees have stingers they are not known to be aggressive and are attracted to native plants including tomato flowers.

During Battery Day, Tesla unveiled a number of advances that will further enhance the company’s electric vehicles, lower their cost, and dramatically improve the ownership experience. One very important improvement is silicon, which the company will use in the anode of the battery cell. Tesla silicon opens the door to.

Don’t be fooled, these ‘babies’ are silicon dolls used for films and for therapy. 😃

Very realistic! 😃

Susan’s silicone dolls look so real, they’re often mistaken for real babies! 😳👶

Watery worlds like Ceres — a dwarf planet in the asteroid belt — hint that our solar system is wetter than we thought. And where there’s water, there might be life.

“I’ve often seen a cat without a grin,” thought Alice. “But a grin without a cat! It’s the most curious thing I ever saw in all my life!”

It’s an experience eminent physicist Yakir Aharonov can relate to. Together with fellow Israeli physicist Daniel Rohrlich, he’s shown theoretically how a particle might show its face in a corner of an experiment without needing its body anywhere in sight.

To be more precise, their analysis argues information could be transferred between two points without an exchange of particles.

A joint study led by City University of Hong Kong (CityU) has built an ultralow-power consumption artificial visual system to mimic the human brain, which successfully performed data-intensive cognitive tasks. Their experiment results could provide a promising device system for the next generation of artificial intelligence (AI) applications.

The research team is led by Professor Johnny Chung-yin Ho, Associate Head and Professor of the Department of Materials Science and Engineering (MSE) at CityU. Their findings have been published in the scientific journal Science Advances, titled “Artificial visual system enabled by quasi-two-dimensional electron gases in oxide superlattice nanowires.”

As the advances in semiconductor technologies used in digital computing are showing signs of stagnation, neuromorphic (brain-like) computing systems have been regarded as one alternative. Scientists have been trying to develop the next generation of advanced AI computers, which could be as lightweight, energy-efficient and adaptable as the human brain.

Finding alternatives to antibiotics is one of the biggest challenges facing the research community. Bacteria are increasingly resistant to these drugs, and this resistance leads to the deaths of more than 25,000 around the world. Now, a multidisciplinary team of researchers from the Universitat Rovira i Virgili, the University of Grenoble (France), the University of Saarland (Germany) and RMIT University (Australia) have discovered that the mechanical deformation of bacteria is a toxic mechanism that can kill bacteria with gold nanoparticles. The results of this research have been published in the journal Advanced Materials and are a breakthrough in researchers’ understanding the antibacterial effects of nanoparticles and their efforts to find new materials with bactericide properties.

Since the times of Ancient Egypt, gold has been used in a range of medical applications and, more recently, as for diagnosing and treating diseases such as cancer. This is due to the fact that gold is a chemically inert material, that is, it does not react or change when it comes into contact with an organism. Amongst the scientific community, nanoparticles are known for their ability to make tumors visible and for their applications in nanomedicine.

This new research shows that these chemically inert nanoparticles can kill bacteria thanks to a physical mechanism that deforms the cell wall. To demonstrate this, the researchers have synthesized in the laboratory gold nanoparticles in the shape of an almost perfect sphere and others in the shape of stars, all measuring 100 nanometres (8 times thinner than a hair). The group analyzed how these particle interact with living bacteria. “We find that the bacteria become deformed and deflate like a ball that is having the air let out before dying in the presence of these nanoparticles,” explained Vladimir Baulin, researcher at the Department of Chemical Engineering of the URV. The researchers state the bacteria seem to have died after a massive leak, “as if the cell wall had spontaneously exploded.”
