Scientists discover massive ‘extragalactic structure’ behind the Milky Way

Posted by in categories: energy, space

Astronomers have detected an enormous extragalactic structure hiding in an uncharted region of space far beyond the Milky Way ‘s center.

This phantom region, known as the zone of avoidance, is a blank spot on our map of the universe, comprising somewhere between 10% and 20% of the night sky. The reason we can’t see it — at least with standard visible light telescopes — is because the Milky Way’s bulging center blocks our view of it; the center of our galaxy is so dense with stars, dust and other matter that light from the zone of avoidance gets scattered or absorbed before reaching Earth’s telescopes.

However, researchers have had better luck uncovering the zone’s secrets with telescopes that can detect infrared radiation — a type of energy that’s invisible to human eyes, but powerful enough to shine through dense clouds of gas and dust. Infrared surveys of the zone of avoidance have found evidence of thousands of individual galaxies shining through the cosmic fog, though little is known about the large-scale structures that lurk there.

Researchers find why Cancer cells require proteins, copper

Posted by in categories: biotech/medical, chemistry

Researchers revealed why cancer cells require proteins that fix copper ions in order to develop and spread throughout the human body. Possible novel treatment targets have been discovered as a result of recent research on the connections between proteins and how they bind to metals in cancer-related proteins.

Small amounts of the metal copper are required by human cells to perform essential biological functions. The conclusion drawn from studies demonstrating higher copper levels in tumor cells and blood serum from cancer patients is that cancer cells require more copper than healthy cells. Additionally, more copper-binding proteins are active when copper levels are higher. “Therefore, these proteins are highly important to study when it comes to understanding the development of cancer and deeper knowledge about them can lead to new targets for treatment of the disease,” said Pernilla Wittung-Stafshede, Professor of Chemical Biology at Chalmers University of Technology, Sweden.

Most cancer-related deaths are due to the fact that metastases — secondary tumors — form in several places in the body, for example, in the liver or lungs. A protein called Memo1 is part of the signaling systems that cancer cells use to grow and spread around the body. Previous research has shown that when the gene for Memo1 is inactivated in breast cancer cells, their ability to form metastases decreases. A research group from Chalmers wanted to take a closer look at the connection between Memo1 and copper. In a new study published in the scientific journal PNAS, the researchers examined the Memo1 protein’s ability to bind copper ions through a series of test tube experiments. They discovered that the protein binds copper, but only the reduced form of copper. It is this form of copper ions that is most common in living cells. It’s an important discovery because reduced copper, while it is needed in the body, also contributes to redox-reactions that damage — or even kill — the cells.

AI grain assessment sows seeds for better returns

Posted by in categories: food, mobile phones, robotics/AI

South Australian artificial intelligence (AI) company GoMicro is rolling out its new grain assessment technology in Australia, paving the way towards more consistent quality controls and stable grain and pulse prices.

Based at Flinders University’s high-tech New Venture Institute (NVI) at Tonsley Innovation District in Clovelly Park, Adelaide, GoMicro CEO Dr. Sivam Krish says the multi-grain assessor gives growers and domestic and export markets a quick and better way to grade crops, accurately testing more than 1,200 grains in one sample—compared to the existing scanner-based method which assesses about 200 well-separated grains at a time.

“GoMicro relies on the excellent quality of phone cameras and Amazon web services to deliver low-cost, high-precision quality grain and other produce assessments to farmers worldwide,” says Dr. Krish.

Warning: Popular Vitamin Supplement Causes Cancer Risk and Brain Metastasis

Posted by in categories: biotech/medical, life extension, neuroscience

University of Missouri researchers made the discovery while using bioluminescent imaging technology to study how nicotinamide riboside supplements work inside the body.

Commercial dietary supplements like nicotinamide riboside (NR), a form of vitamin B3, were linked to benefits related to cardiovascular, metabolic, and neurological health in previous studies. However, new research from the University of Missouri (MU) has found NR could actually increase the risk of serious disease, including developing cancer.

Supplements containing nicotinamide riboside are often marketed as NAD+ boosters claimed benefits including increased energy, anti-aging/longevity/healthy aging, improved cellular energy metabolism and repair, increased vitality, and improved heart health.

Unmanned, solar-powered US space plane back after 908 days

Posted by in categories: military, robotics/AI, space travel, sustainability

CAPE CANAVERAL, Fla — An unmanned U.S. military space plane landed early Saturday after spending a record 908 days in orbit for its sixth mission and conducting science experiments.

The solar-powered vehicle, which looks like a miniature space shuttle, landed at NASA’s Kennedy Space Center. Its previous mission lasted 780 days.

Improving the performance of electrodeless plasma thrusters for space propulsion

Posted by in categories: innovation, space travel

A Tohoku University researcher has increased the performance of a high-power electrodeless plasma thruster, moving us one step closer to deeper explorations into space.

Innovations in terrestrial transportation technologies, such as cars, trains, and aircraft, have driven historical technologies and industries so far; now, a similar breakthrough is occurring in space thanks to electric propulsion technology.

Electric propulsion is a technique utilizing to accelerate a propellant and to generate thrust that propels a spacecraft. Space agencies have pioneered electric propulsion technology as the future of space exploration.

Fermi Paradox: Stay At Home Civilizations

Posted by in categories: existential risks, space travel

Today we return to the Fermi Paradox to contemplate the notion of civilizations which neither expand outwards to colonize the galaxy nor go extinct, but exist as long-term, high-tech civilizations just on their own planet or solar system. To discuss the possible motives and reasoning we will look at the many arguments raised for and against space exploration.
