A novel thermally-powered actuator can bend and stretch to move a soft, caterpillar-like robot in more than one direction.

“Brian Cox — Alien Civilizations Decoded,” a captivating journey into the world of extraterrestrial life and our quest to find it. In this riveting video, renowned physicist Brian Cox discusses the implications of making contact with alien civilizations and the role of artificial intelligence in this extraordinary search.

We will explore the various methods scientists use to search for intelligent life beyond our planet, including scanning the skies for radio signals and examining exoplanets for potential habitability. With the recent introduction of AI, researchers have experienced a breakthrough, detecting over 20,000 signals of interest and igniting a renewed passion for finding alien technosignatures.

Nothing quite excites the imagination like pondering on the future.

And not only is science fiction great for exploring ideas surrounding the future, but it is also a great avenue for exploring other realities, such as post-apocalypses, zombie takeovers, and alien invasions.

Doctors are assuring the public that it’s not going to take over the world and kill us all, but it is something we need to be aware of.

March 24, 2023 – At least half a million urinary tract infections are caused by eating meat contaminated with E.coli bacteria, a new study reports.

E.coli is the most common bacteria to cause urinary tract infections, and it usually lives harmlessly in the human intestinal tract, although it is well-known to be a source of food poisoning.

“Most people understand that eating uncooked meat, or accidentally ingesting bacteria from meat, can cause you to have an upset stomach,” said researcher Lance B. Price, a professor at George Washington University, according to The Washington Post. “But now we also know that specific varieties of E. coli, coming from raw meat, are also causing hundreds of thousands of UTIs.”

Tesla Vision Park Assist provides visual and audio alerts of surrounding objects. This feature uses the occupancy network to predict high-definition outlines of objects 360 degrees around the car. Note: Tesla Vision Park Assist is for guidance purposes only and is not a substitute for an aware driver. Please be attentive and avoid obstacles as required.

This is after being parked for a while, interesting to see how park assist takes a bit to load previous data from before it was parked. Still really impressive work from the @Tesla team pic.twitter.com/LONqouXp85

A number of Tesla owners with vision-only cars who received update 2023.6.9 have shared initial videos of Vision Park Assist’s performance in real-world situations. Tesla Model 3 owner @EVBaymax, for one, observed that the distance estimates displayed in the vehicle are quite accurate, almost to the inch. The Model 3 owner actually verified Tesla Vision’s estimates with a tape measure, and it was quite accurate.

The researchers add that these data demonstrate that CRISPRa is generally applicable across chromatin states and cell types, and highlights the factors that impact the degree of gene activation and how easy it is to reproduce the effects. Understanding these factors is important in the design and analysis of CRISPRa screens, which are used to look for genes involved in genetic diseases, the team points out.

Further study is required to continue to add to these rules and to see whether different CRISPRa or CRISPR interference techniques behave in a similar way.

“Our research has established a system for reporting the effectiveness of CRISPR activation in stem cells, allowing us to gain a better understanding of how CRISPRa works in multiple cell states,” says Qianxin Wu, PhD, first author from Wellcome Sanger. “We also showed that CRISPR gene activation is powerful enough to induce stem cells to differentiate into other cell states. This suggests that CRISPRa screens can be used to search for genes involved in cellular processes or to generate more accurate models of cell types in the body, aiding research into genetic diseases and regenerative medicine.”

We don’t want to alarm you, but there’s a black hole pointing Earth squarely in the face.

Scientists have reclassified a galaxy after finding that the supermassive black hole in its centre has changed direction and it is now aiming right at us.
