Study challenges evolutionary theory that DNA mutations are random

Posted by in categories: biotech/medical, evolution, food

A simple roadside weed may hold the key to understanding and predicting DNA mutation, according to new research from University of California, Davis, and the Max Planck Institute for Developmental Biology in Germany.

The findings, published January 12 in the journal Nature, radically change our understanding of evolution and could one day help researchers breed better crops or even help humans fight cancer.

Mutations occur when DNA is damaged and left unrepaired, creating a new variation. The scientists wanted to know if mutation was purely random or something deeper. What they found was unexpected.

New Silicon Carbide Qubits Bring Us One Step Closer to Quantum Networks

Posted by in categories: quantum physics, supercomputing

Chromium defects in silicon carbide may provide a new platform for quantum information.

Quantum computers may be able to solve science problems that are impossible for today’s fastest conventional supercomputers. Quantum sensors may be able to measure signals that cannot be measured by today’s most sensitive sensors. Quantum bits (qubits) are the building blocks for these devices. Scientists are investigating several quantum systems for quantum computing and sensing applications. One system, spin qubits, is based on the control of the orientation of an electron’s spin at the sites of defects in the semiconductor materials that make up qubits. Defects can include small amounts of materials that are different from the main material a semiconductor is made of. Researchers recently demonstrated how to make high quality spin qubits based on chromium defects in silicon carbide.

Researchers from DARPA, NASA and MIT working to develop Anti-Gravity technologies

Posted by in categories: engineering, transportation

Anyone able to find the sources? 🤔


Antigravity is the concept of a technology that, when applied to an item or a place, allows it to “cancel” gravity rather than compensate for it, as in the case of an aircraft.

Since November 2020, a group of experts from NASA, DARPA, MIT, and the Air Force has met on Zoom on a monthly basis to explore future propulsion technology, including the possible “antigravity.” Given that this technology now exists only in science fiction or in the thoughts of a few dreamer thinkers, this is a remarkable occurrence.

Rolls-Royce Says Its Electric Plane Just Smashed the World Record for Speed

Posted by in categories: sustainability, transportation

The first electric plane took flight in 1973. There was just one person on board and the plane only stayed in the air for 14 minutes, but it was the beginning of an ongoing effort to power aircraft with batteries instead of fuel. Multiple companies are working on building faster, lighter, more efficient electric planes, as well as batteries to power those planes—and last week an aircraft made by Rolls-Royce hit some new milestones in the industry.

Cheerily dubbed the Spirit of Innovation, the plane is part of the company’s Accelerating the Electrification of Flight initiative. The seemingly precocious plane just completed its maiden flight a little over a month ago, and Rolls-Royce subsequently launched “an intense flight testing phase” to collect data on the performance of the aircraft’s power and propulsion system, a 400kW electric powertrain they call “the most power-dense propulsion battery pack ever assembled in aerospace.”

Last week, the company said in a press release, they set three new world records. First, the aircraft reached a top speed of 345.4 mph (555.9 km/h) over 1.8 miles (3 kilometers). That’s 132 mph (213 k/h) faster than the existing record. The Spirit of Innovation got up to an altitude of 9,842.5 feet (3,000 meters) in 202 seconds—60 seconds faster than the existing record. And finally, the plane reached a maximum speed of 387.4 mph (623 km/h) during its flight tests, which Rolls-Royce says makes it the world’s fastest all-electric vehicle. The company is waiting on the Federal Aviation Institute to confirm and certify these claims.

You won’t Believe what China is doing now! — China Modifying the Weather

Posted by in categories: climatology, geoengineering

Chinese Scientists have previously showed their ability to change and control the weather inside China, but now there’s proof that they may actually modify and control the weather all over the world which has disastrous results in the form of Natural DIsasters such as Tornadoes. This video explores the possiblity of China having done this knowingly and what good could possibly come from having the ability to change the climate at your will. One thing is for sure, the science and technology behind these abilities is truly breathtaking.

SCO2 Turbomachinery Developed for Concentrated Solar Power Plant

Posted by in categories: government, solar power, sustainability

Southwest Research Institute worked with government and commercial collaborators to successfully develop and demonstrate full-scale turbomachinery for one of the world’s first supercritical carbon dioxide (sCO2) power systems for a concentrated solar power (CSP) plant. The technology combines sCO2 power cycles with integrated thermal energy storage.

The project was supported by the U.S. Department of Energy’s APOLLO program, which was created to improve performance and reduced the cost of electricity from CSP plants. The 10MW sCO2 turbomachinery has successfully completed performance and endurance tests in a closed-loop environment.

SCO2 is carbon dioxide held above a critical temperature and pressure, which causes it to act like a gas while having the density of a liquid. It’s also nontoxic and nonflammable, having been used in dry cleaning processes, low-GHG refrigeration systems, as well as to decaffeinate coffee.

Newly Discovered Type of “Strange Metal” — Material That Shares Fundamental Quantum Attributes With Black Holes

Posted by in categories: cosmology, quantum physics

A new discovery could help scientists to understand “strange metals,” a class of materials that are related to high-temperature superconductors and share fundamental quantum attributes with black holes.

Scientists understand quite well how temperature affects electrical conductance in most everyday metals like copper or silver. But in recent years, researchers have turned their attention to a class of materials that do not seem to follow the traditional electrical rules. Understanding these so-called “strange metals” could provide fundamental insights into the quantum world, and potentially help scientists understand strange phenomena like high-temperature superconductivity.

Now, a research team co-led by a Brown University physicist has added a new discovery to the strange metal mix. In research published in the journal Nature, the team found strange metal behavior in a material in which electrical charge is carried not by electrons, but by more “wave-like” entities called Cooper pairs.

Where Are Memories Stored in the Brain? They May Be in the Connections Between Your Brain Cells

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

All memory storage devices, from your brain to the RAM in your computer, store information by changing their physical qualities. Over 130 years ago, pioneering neuroscientist Santiago Ramón y Cajal first suggested that the brain stores information by rearranging the connections, or synapses, between neurons.

Since then, neuroscientists have attempted to understand the physical changes associated with memory formation. But visualizing and mapping synapses is challenging to do. For one, synapses are very small and tightly packed together. They’re roughly 10 billion times smaller than the smallest object a standard clinical MRI can visualize. Furthermore, there are approximately 1 billion synapses in the mouse brains researchers often use to study brain function, and they’re all the same opaque to translucent color as the tissue surrounding them.

MIT Scientists Overcome a Major Bottleneck in Carbon Dioxide Conversion

Posted by in categories: chemistry, sustainability

Study reveals why some attempts to convert the greenhouse gas into fuel have failed, and offers possible solutions.

If researchers could find a way to chemically convert carbon dioxide into fuels or other products, they might make a major dent in greenhouse gas emissions. But many such processes that have seemed promising in the lab haven’t performed as expected in scaled-up formats that would be suitable for use with a power plant or other emissions sources.

Now, researchers at MIT.
