Plate tectonics 4 billion years ago may have helped initiate life on Earth

Posted by in category: futurism

The Earth’s oldest surface layer forming continents, termed its crust, is approximately 4 billion years old and is comprised of 25–50km-thick volcanic rocks known as basalts. Originally, scientists thought that one complete lithospheric crust covered the entire planet, compared to the individual plates we see today which were believed to have only begun formation 1 billion years later. However, attitudes towards this hypothesis are being challenged.

The formation mechanism of this is somewhat enigmatic, with academics now suggesting it may have been driven by , the movement of Earth’s major surface plates across the globe over billions of years, forming the landmasses and topographic features which we see today.

One theory focuses on when the plates converge, often causing one to subduct beneath the other, resulting in partial melting to change magma composition, while another studies mechanisms occurring within the itself (at less than 50km depth) that are entirely separate from plate boundaries but also cause partial melting.

Innovative Gene Screening in Human Tissue May Unlock Autism’s Secrets

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

Summary: Researchers pioneered a groundbreaking method called “CHOOSE” to investigate genes tied to autism spectrum disorder (ASD) within human tissue. This technique allows for simultaneous examination of key transcriptional regulator genes linked to autism in a single organoid.

Utilizing CHOOSE, the team pinpointed mutations in 36 genes known to heighten autism risk, shedding light on how they influence brain development. The revelations from these organoids mirrored clinical observations, underscoring the potential of this method in advancing our understanding of neurodevelopmental disorders.

New study uncovers origin of ‘conscious awareness’

Posted by in category: climatology

Living things act with purpose. But where does purpose come from? How do humans make sense of their relation to the world and realize their ability to effect change? These fundamental questions of “agency”—acting with purpose—have perplexed some of the greatest minds in history including Sir Isaac Newton, Charles Darwin, Erwin Schrödinger and Niels Bohr.

A Florida Atlantic University (FAU) study reveals groundbreaking insight into the origins of agency using an unusual and largely untapped source— . Since goal-directed action appears in the first months of human life, the FAU research team used young infants as a test field to understand how spontaneous movement transforms into purposeful action.

Scientists discover nanofabrication of photonic crystals on buried ancient Roman glass

Posted by in category: futurism

Some 2,000 years ago in ancient Rome, glass vessels carrying wine or water, or perhaps an exotic perfumes, tumble from a table in a marketplace, and shatter to pieces on the street. As centuries passed, the fragments were covered by layers of dust and soil and exposed to a continuous cycle of changes in temperature, moisture, and surrounding minerals.

Now these tiny pieces of are being uncovered from construction sites and archaeological digs and reveal themselves to be something extraordinary. On their surface is a mosaic of iridescent colors of blue, green and orange, with some displaying shimmering gold-colored mirrors.

These beautiful glass artifacts are often set in jewelry as pendants or earrings, while larger, more complete objects are displayed in museums.

Meet the climate innovators of tomorrow

Posted by in categories: climatology, robotics/AI, sustainability

We’ve highlighted a lot of bright innovators over the years, usually before they become household names. Sergey Brin of Google was on the list in 2002. JB Straubel was honored in 2008 when he was CTO of Tesla. That year also saw Andrew Ng make the list (he’s one of the biggest names in AI right now, and he came back this year to write an intro essay, which I highly recommend.)

As I looked through the folks who made the list in the climate and energy category in 2023, I noticed a few trends. In particular, there was a concentration in two areas I think a lot about: batteries and fuels. So let’s take a closer look at a few of this year’s innovators and consider what their work could mean for the future of climate action.

Intel’s Glass Substrates Are Essential For Future IC Development

Posted by in categories: computing, futurism

While semiconductor lithography gets the bulk of the attention in chipmaking, other processes are equally important in producing working integrated circuits (ICs). Case in point: packaging. An IC package provides the electrical, thermal, and mechanical transition from the semiconductor die or chip to the circuit board, which is often called a motherboard. One key element of the IC package is the substrate, which is essentially a miniature circuit board with copper traces that bonds to the input/output (I/O), power and ground pads on the chip and electrically connects these pads to the circuit board. The substrate provides a solid mechanical home for the chip and is also thermally matched to… More.

The release also quotes Babak Sabi, Intel senior vice president and general manager of Assembly and Test Development, who said: “After a decade of research, Intel has achieved industry-leading glass substrates for advanced packaging. We look forward to delivering these cutting-edge technologies that will benefit our key players and foundry customers for decades to come.”

Research into using glass substrates for chipmaking is nothing new. As Intel’s release says, the company has been working on this technology for at least a decade, as have other organizations such as the 3D Systems Packaging Research Center located at Georgia Tech, which was founded in 1994 – nearly 30 years ago. Last year, the Georgia Tech PRC launched an industry advisory board with Intel Fellow Ravi Mahajan as one of the initial board members. Intel has already spent more than a billion dollars to develop a glass-substrate manufacturing facility at its site in Chandler, Arizona.

OpenAI And Others Help Educators Navigate AI

Posted by in categories: education, robotics/AI

As instructors settle into a new academic year, AI technologies like ChatGPT offer new dimensions for teaching and student engagement. While the allure of AI is captivating, the chatbots are still in their formative stages and thus imperfect, sometimes producing a mix of facts and fiction and raising an array of questions about academic integrity.

Many higher education institutions have recently changed their stances on the tools, from banning them last spring to allowing instructors to use the technology in their classes this fall. While the overwhelming majority of higher education institutions lack formal policies on the use of AI, according to research by Tayton Partners, some have… More.

Opportunities and challenges AI presents in academia, and how educators can navigate this emerging landscape. Discussing guides offered by OpenAI and universities.

CERN researchers continue to look for elusive monopoles

Posted by in category: particle physics

New advances were made from LHC Run 2 data obtained between 2015 and 2018 but the scientists are yet to spot the monopoles.

Researchers at the European Council for Nuclear Research (CERN) are among those physicists who have been looking for magnetic monopoles. A recently published paper from the ATLAS Collaboration at CERN has confirmed that it continues to look for the elusive particle, a press release said.

The ATLAS Collaboration is one of science’s most significant collaborative efforts. Its webpage states that it consists of 0 members and 3,000 scientific authors comprised of physicists, engineers, technicians, students, and support staff from around the world.
