Quasar ‘clocks’ show the universe was five times slower soon after the Big Bang

Posted by in categories: cosmology, physics

Scientists have for the first time observed the early universe running in extreme slow motion, unlocking one of the mysteries of Einstein’s expanding universe. The research is published in Nature Astronomy.

Einstein’s general theory of relativity means that we should observe the distant—and hence ancient— running much slower than the present day. However, peering back that far in time has proven elusive. Scientists have now cracked that mystery by using as “clocks.”

New laser-based method could help scientists discover new puncture-resistant materials

Posted by in categories: particle physics, weapons

A bullet piercing the protective armor of a first responder, a jellyfish stinging a swimmer, micrometeorites striking a satellite: High-speed projectiles that puncture materials show up in many forms. Researchers constantly aim to identify new materials that can better resist these high-speed puncture events, but it has been hard to connect the microscopic details of a promising new material to its actual behavior in real-world situations.

To address this issue, researchers at the National Institute of Standards and Technology (NIST) have designed a method that uses a high-intensity laser to blast microscale projectiles into a small sample at velocities that approach the speed of sound. The system analyzes the energy exchange between the particle and the sample of interest at the micro level then uses scaling methods to predict the puncture resistance of the material against larger energetic projectiles, such as bullets encountered in real-world situations. This new method, described in the journal ACS Applied Materials & Interfaces, reduces the need to perform a lengthy series of lab experiments with larger projectiles and bigger samples.

“When you’re investigating a for its protective applications, you don’t want to waste time, money and energy in scaling up your tests if the material doesn’t pan out. With our new method we can see earlier if it’s worth looking into a material for its protective properties,” said NIST chemist Katherine Evans.

New eclipsing cataclysmic variable system discovered

Posted by in category: space travel

Using the Spektr-RG (SRG) spacecraft and the Zwicky Transient Facility (ZTF), an international team of astronomers has discovered a new eclipsing cataclysmic variable system, which received designation SRGeJ045359.9+622444 (or SRGeJ0453 for short). The finding is reported in a paper published June 22 on the pre-print server arXiv.

Cataclysmic variables (CVs) are consisting of a white dwarf primary that is accreting matter from a normal star companion. They irregularly increase in brightness by a large factor, then drop back down to a quiescent state. These binaries have been found in many environments, such as the center of the Milky Way galaxy, the solar neighborhood, and within open and globular clusters.

AM CVn stars (named after the star AM Canum Venaticorum), are a rare type of CV in which a white dwarf accretes hydrogen-poor matter from a compact companion star. In general, such systems are helium-rich binaries, not showing traces of hydrogen in their spectra, with between five and 65 minutes.

Run for the Hills on Apple Podcasts

My Sony Music interview is now out. 40 min of #transhumanism adventures, AI, Transhumanist Bill of Rights, & politics. A professional team of producers and host Katherine Rowland put this together! It’s really fun and unique!


In 2015, journalist Zoltan Istvan became the first person to run for president on a transhumanist platform. His campaign centered a right to unlimited life for all humans…as well as cyborgs and robots. Zoltan Istvan believes that how people treat AI will become the civil rights battle of our time. And that he would be the right leader to help guide America through the singularity.

That is, of course, until the AI revolution actually began.

A user-friendly platform for virtual exploration of chemical reactions

Posted by in categories: chemistry, computing

A new online platform to explore computationally calculated chemical reaction pathways has been released, allowing for in-depth understanding and design of chemical reactions.

Advances in have lead to the discovery of new reaction pathways for the synthesis of high-value compounds. Computational chemistry generates much data, and the process of organizing and visualizing this data is vital to be able to utilize it for future research.

A team of researchers from Hokkaido University, led by Professor Keisuke Takahashi at the Faculty of Chemistry and Professor Satoshi Maeda at the Institute for Chemical Reaction Design and Discovery (WPI-ICReDD), have developed a centralized, interactive, and user-friendly platform, Searching Chemical Action and Network (SCAN), to explore reaction pathways generated by computational chemistry. Their research was published in the journal Digital Discovery.

Study Helps Identify Genetic Changes That Make Us Human

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

Humans split away from our closest animal relatives, chimpanzees, and formed our own branch on the evolutionary tree about seven million years ago. In the time since—brief, from an evolutionary perspective—our ancestors evolved the traits that make us human, including a much bigger brain than chimpanzees and bodies that are better suited to walking on two feet. These physical differences are underpinned by subtle changes at the level of our DNA. However, it can be hard to tell which of the many small genetic differences between us and chimps have been significant to our evolution.

New research from Whitehead Institute Member Jonathan Weissman; University of California, San Francisco Assistant Professor Alex Pollen; Weissman lab postdoc Richard She; Pollen lab graduate student Tyler Fair; and colleagues uses cutting edge tools developed in the Weissman lab to narrow in on the key differences in how humans and chimps rely on certain genes. Their findings, published in the journal Cell on June 20, may provide unique clues into how humans and chimps have evolved, including how humans became able to grow comparatively large brains.

Beyond the Helix: DNA’s Complex Folding Unveils New Functions

Posted by in categories: biotech/medical, government, health

In a groundbreaking study, researchers from Weill Cornell Medicine and the National Heart, Lung, and Blood Institute, a department of the National Institutes of Health.

The National Institutes of Health (NIH) is the primary agency of the United States government responsible for biomedical and public health research. Founded in 1,887, it is a part of the U.S. Department of Health and Human Services. The NIH conducts its own scientific research through its Intramural Research Program (IRP) and provides major biomedical research funding to non-NIH research facilities through its Extramural Research Program. With 27 different institutes and centers under its umbrella, the NIH covers a broad spectrum of health-related research, including specific diseases, population health, clinical research, and fundamental biological processes. Its mission is to seek fundamental knowledge about the nature and behavior of living systems and the application of that knowledge to enhance health, lengthen life, and reduce illness and disability.

Unraveling a Quantum Enigma: How Tantalum Enhances Qubit Performance

Posted by in categories: chemistry, computing, nanotechnology, quantum physics

Whether it’s baking a cake, constructing a building, or creating a quantum device, the caliber of the finished product is greatly influenced by the components or fundamental materials used. In their pursuit to enhance the performance of superconducting qubits, which form the bedrock of quantum computers, scientists have been probing different foundational materials aiming to extend the coherent lifetimes of these qubits.

Coherence time serves as a metric to determine the duration a qubit can preserve quantum data, making it a key performance indicator. A recent revelation by researchers showed that the use of tantalum in superconducting qubits enhances their functionality. However, the underlying reasons remained unknown – until now.

Scientists from the Center for Functional Nanomaterials (CFN), the National Synchrotron Light Source II (NSLS-II), the Co-design Center for Quantum Advantage (C2QA), and Princeton University investigated the fundamental reasons that these qubits perform better by decoding the chemical profile of tantalum.
