Astronomers Discover Supermassive Black Hole Pointing Directly at Earth

Posted by in category: cosmology

Earlier this year, scientists discovered that a “jet,” created by a very distant supermassive black hole, sent an accumulation of various space matter rocketing directly toward Earth. Scientists haven’t expressed any need for concern about the jet. However, they are intrigued by the sheer brightness of it and the vast distance between it and Earth.

Researchers harness bacteria-eating viruses to create powerful food decontamination spray

Posted by in categories: bioengineering, food, nanotechnology

Researchers at McMaster University have created a powerful new weapon against bacterial contamination and infection.

They have developed a way to coax bacteriophages—harmless viruses that eat bacteria—into linking together and forming microscopic beads. Those beads can safely be applied to and other materials to rid them of harmful pathogens such as E. coli 0157. Each bead is about 20 microns, (one 50th of a millimeter) in diameter and is loaded with millions of phages.

The McMaster engineering team behind the invention, led by professors Zeinab Hosseinidoust, who holds the Canada Research Chair in Bacteriophage Bioengineering, and Tohid Didar, who holds the Canada Research Chair in Nano-Biomaterials, and graduate student Lei Tian, have created a spray using nothing but the microbeads.

AI bot ChatGPT stuns academics with essay-writing skills and usability

Posted by in categories: Elon Musk, robotics/AI

Professors, programmers and journalists could all be out of a job in just a few years, after the latest chatbot from the Elon Musk-founded OpenAI foundation stunned onlookers with its writing ability, proficiency at complex tasks, and ease of use.

The system, called ChatGPT, is the latest evolution of the GPT family of text-generating AIs. Two years ago, the team’s previous AI, GPT3, was able to generate an opinion piece for the Guardian, and ChatGPT has significant further capabilities.

Most Effective Treatment Yet: New Radioactive Tumor Implant Obliterates Pancreatic Cancer

Posted by in category: biotech/medical

Duke University biomedical engineers have demonstrated the most effective pancreatic cancer treatment yet recorded in mouse models. While most mouse trials consider just stopping growth to be a success, the new treatment fully eliminated tumors in 80% of mice across many model types, including those considered to be the most difficult to treat.

The approach combines traditional chemotherapy drugs with a new method for irradiating the tumor. The treatment implants radioactive iodine-131 directly into the tumor inside a gel-like depot that protects healthy tissue and is absorbed by the body once the radiation fades, as opposed to administering radiation from an external beam that passes through healthy tissue.

The study was recently published in the journal Nature Biomedical Engineering.

How the Broca’s Area of the Brain Helps Children Easily Learn Grammar

Posted by in category: neuroscience

Summary: The development of a child’s general and grammatical linguistic abilities between the ages of 3 to 4 is accompanied by the maturation of brain structures within the “language network”.

Anyone who has ever learned a foreign language knows how laborious it is to acquire vocabulary and grammar. In contrast, children acquire their first language seemingly effortlessly. By the age of four, many children are already speaking without errors and can draw on a large vocabulary.
