Scientists Have Traced Earth’s Path Through the Galaxy via Tiny Crystals Found in the Crust

Posted by in category: space

The Rhythm of Crust Production on Earth

Many rocks on Earth form from molten or semi-molten magma. This magma is derived either directly from the mantle—the predominantly solid but slowly flowing layer below the planet’s crust—or from recooking even older bits of pre-existing crust. As liquid magma cools, it eventually freezes into solid rock.

Through this cooling process of magma crystallization, mineral grains grow and can trap elements such as uranium that decay over time and produce a sort of stopwatch, recording their age. Not only that, but crystals can also trap other elements that track the composition of their parental magma, like how a surname might track a person’s family.

Scientists say TOI-1452b, exoplanet 100 light years from Earth, may be covered with deep ocean

Posted by in category: space

Aug. 24 (UPI) — A team of researchers have discovered an exoplanet about 100 light years away from Earth in the Draco constellation, and they say the world appears to be covered in a deep ocean.

The exoplanet — called TOI-1452b — is slightly larger than the Earth and is located in a “Goldilocks zone,” where temperatures are neither too hot nor too cold for liquid water to exist. Therefore, astronomers think TOI-1452b could be covered in an ocean.

A new concept for low-cost batteries

Posted by in categories: solar power, sustainability

As the world builds out ever larger installations of wind and solar power systems, the need is growing fast for economical, large-scale backup systems to provide power when the sun is down and the air is calm. Today’s lithium-ion batteries are still too expensive for most such applications, and other options such as pumped hydro require specific topography that’s not always available.

Now, researchers at MIT and elsewhere have developed a new kind of battery, made entirely from abundant and inexpensive materials, that could help to fill that gap.

The new battery architecture, which uses aluminum and sulfur as its two electrode materials, with a molten salt electrolyte in between, is described today in the journal Nature, in a paper by MIT Professor Donald Sadoway, along with 15 others at MIT and in China, Canada, Kentucky, and Tennessee.

GAMEOPT: An algorithm to optimize the flow of vehicles through dynamic unsignalized intersections

Posted by in categories: energy, information science, mathematics, transportation

Managing road intersections in crowded and dynamic environments, such as urban areas, can be highly challenging. The poor management of traffic at these can lead to road accidents, wastage of fuel, and environmental pollution.

Researchers at the University of Maryland have recently developed GAMEOPT, a that could help manage unsignalized road intersections with high traffic more efficiently. The research team with members, Nilesh Suriyarachchi, Rohan Chandra, John S. Baras and Dinesh Manocha introduced their method in a recent paper to be published in the proceedings of the 25th IEEE International Conference on Intelligent Transportation Systems (IEEE ITSC 2022). This method combines optimization techniques with ideas from game theory, a mathematical construct that represents situations in which different agents are competing with one another.

Forty percent of all crashes, 50% of serious collisions, and 20% of fatalities occur at unsignalized intersections,” Chandra, a member of the research team, told TechXplore. “Our primary objective is to improve traffic flow and in poorly regulated or unregulated traffic intersections. To achieve this objective, we propose an algorithm that combines ideas from optimization and game theory to understand how different traffic agents cooperate and negotiate with each other at traffic intersections.”

PPE can be recycled to make stronger concrete

Posted by in categories: biotech/medical, sustainability

Engineers at RMIT University have developed a method to use disposable personal protective equipment (PPE) to make concrete stronger, providing an innovative way to significantly reduce pandemic-generated waste.

The RMIT team is the first to investigate the feasibility of recycling three key types of PPE—isolation gowns, face masks and rubber gloves—into concrete.

Published in the journals Case Studies in Construction Materials, Science of the Total Environment and Journal of Cleaner Production, the studies by RMIT School of Engineering researchers demonstrate the potential for PPE to be used as reinforcement materials in structural concrete.

Bank Islam picks Amazon Web Services as cloud provider

Posted by in category: finance

KUALA LUMPUR (Aug 1): Bank Islam Malaysia Bhd has picked Amazon Web Services (AWS) as its cloud provider to power its digital transformation.

In a statement on Monday (Aug 1), AWS said the bank is using the breadth and depth of AWS’ cloud capabilities, including containers, networking, and content delivery, to build the Be U digital bank to help customers better manage their finances.

The company said Bank Islam is building Be U through its Centre of Digital Experience, an independent division that is developing new banking services on AWS to transform customer experiences.

Study points to new approach to clearing toxic waste from brain

Posted by in categories: biotech/medical, genetics, neuroscience

Researchers at Washington University School of Medicine in St. Louis have found a new druggable pathway that potentially could be used to help prevent Alzheimer’s dementia.

Amyloid beta accumulation in the brain is the first step in the development of Alzheimer’s dementia. Scientists have poured countless hours and millions of dollars into finding ways to clear amyloid away before cognitive symptoms arise, with largely disappointing results.

In this study, published Aug. 24 in the journal Brain, researchers found a way to increase clearance of waste products from the brains of mice by ramping up a genetic quirk known as readthrough. This same strategy also may be effective for other characterized by the buildup of toxic proteins, such as Parkinson’s disease, the researchers said.
