Comet -ATLAS may have been a Blast from the Past

Comet ATLAS may have been a blast from the past
This pair of Hubble Space Telescope images of comet C/2019 Y4 (ATLAS), taken on April 20 and April 23, 2020, reveal the breakup of the solid nucleus of the comet. Hubble photos identify as many as 30 separate fragments. The comet was approximately 91 million miles from Earth when the images were taken. The comet may be a broken off piece of a larger comet that swung by the Sun 5,000 years ago. The comet has been artificially colored in this view to enhance details for analysis.

It’s suspected that about 5,000 years ago a comet may swept within 23 million miles of the Sun, closer than the innermost planet Mercury...

Scientists around the world are developing new hardware for quantum computers, a new type of device that could accelerate drug design, financial modeling, and weather prediction. These computers rely on qubits but these are fickle, degrading into regular bits when interactions with surrounding matter interfere. But new research at MIT suggests a way to protect their states, using a phenomenon called many-body localization (MBL).

MBL is a peculiar phase of matter, proposed decades ago, that is unlike solid or liquid. Typically, matter comes to thermal equilibrium with its environment...

Researchers find Protein may Protect against Neurodegenerative diseases

Taking advantage of knowledge on translation, Hiroshima University researchers examined whether the translational regulatory protein 5MP can suppress RAN translation, which would also suppress the production of the toxic repeat peptide products.

An international research team may have found that a protein implicated in tumor growth may be able to help regulate awry cellular translation and protect against neuronal decay.

Cells translate their genetic material at rapid rates with exquisite precision to reproduce, repair damage or even combat disease. But the process can deregulate and give rise to disease...

Scientists develop new technique for large-scale energy storage

The sale of electric vehicles (EVs) has grown exponentially in the past few years as has the need for renewable energy sources to power them, such as solar and wind. There were nearly 1.8 million registered electric vehicles in the U.S. as of 2020, which is more than three times as many in 2016, according to the International Energy Agency (IEA).

Electric vehicles require power to be available anywhere and anytime, without delays in recharging, but solar and wind are intermittent energy sources that are not available on demand. And the electricity they do generate needs to be stored for later use and not go to waste. That’s where Dr...
