Science X Newsletter Week 07

Dear Reader ,

Here is your customized Science X Newsletter for week 07:

Fossilized insect from 100 million years ago is oldest record of primitive bee with pollen

Beetle parasites clinging to a primitive bee 100 million years ago may have caused the flight error that, while deadly for the insect, is a boon for science today.

ESO telescope sees surface of dim Betelgeuse

Using ESO's Very Large Telescope (VLT), astronomers have captured the unprecedented dimming of Betelgeuse, a red supergiant star in the constellation of Orion. The stunning new images of the star's surface show not only the fading red supergiant but also how its apparent shape is changing.

Study uncovers new electronic state of matter

A research team led by professors from the University of Pittsburgh Department of Physics and Astronomy has announced the discovery of a new electronic state of matter.

Fast radio burst with steady 16-day cycle observed

A large team of space scientists working in Canada has found evidence of a fast radio burst with a steady 16-day cycle. The team has published a paper describing their findings on the arXiv preprint server.

Artificial atoms create stable qubits for quantum computing

Quantum engineers from UNSW Sydney have created artificial atoms in silicon chips that offer improved stability for quantum computing.

Meet T-Rex's older cousin: The Reaper of Death

Scientists said Monday they had discovered a new species of dinosaur closely related to Tyrannosaurus rex that strode the plain of North America some 80 million years ago.

Scientists show solar system processes control the carbon cycle throughout Earth's history

The world is waking up to the fact that human-driven carbon emissions are responsible for warming our climate, driving unprecedented changes to ecosystems, and placing us on course for the sixth mass extinction event in Earth's history.

Disease found in fossilized dinosaur tail afflicts humans to this day

The fossilized tail of a young dinosaur that lived on a prairie in southern Alberta, Canada, is home to the remains of a 60-million-year-old tumor.

Antarctica registers record temperature of over 20 C

Scientists in Antarctica have recorded a new record temperature of 20.75 degrees Celsius (69.35 Fahrenheit), breaking the barrier of 20 degrees for the first time on the continent, a researcher said Thursday.

Time crystals and topological superconductors merge

"Powering a topological superconductor using a time crystal gives you more than the sum of its parts," says Jason Alicea, a researcher at California Institute of Technology (Caltech) in the US. The discovery of topological states has bred reams of research revealing new condensed matter and quantum physics, with potential technological applications in spintronics and quantum computing. Similarly, not long after the first observations of topological insulators in the late 2000s, the concepts of time crystals emerged, introducing another fresh arena for exploring new physics that could be exploited in precise timekeeping and quantum technologies.

NASA flights detect millions of Arctic methane hotspots

Knowing where emissions are happening and what's causing them brings us a step closer to being able to forecast the region's impact on global climate.

Breakthrough Listen releases 2 petabytes of data from SETI survey of Milky Way

The Breakthrough Listen Initiative today released data from the most comprehensive survey yet of radio emissions from the plane of the Milky Way Galaxy and the region around its central black hole, and it is inviting the public to search the data for signals from intelligent civilizations.

Huge bacteria-eating viruses close gap between life and non-life

Scientists have discovered hundreds of unusually large, bacteria-killing viruses with capabilities normally associated with living organisms, blurring the line between living microbes and viral machines.

Deconstructing Schrödinger's cat

The paradox of Schrödinger's cat—the feline that is, famously, both alive and dead until its box is opened—is the most widely known example of a recurrent problem in quantum mechanics: its dynamics seem to predict that macroscopic objects (like cats) can, sometimes, exist simultaneously in more than one completely distinct state. Many physicists have tried to solve this paradox over the years, but no approach has been universally accepted. Now, however, theoretical physicist Franck Laloë from Laboratoire Kastler Brossel (ENS-Université PSL) in Paris has proposed a new interpretation that could explain many features of the paradox. He sets out a model of this possible theory in a new paper in EPJ D.

Secularism and tolerance of minority groups predicts future prosperity of countries

Secular cultures which are tolerant of minority groups and respectful of individuals' rights tend to have more wealth, education and democracy, a new study by University of Bristol scientists has found.

New material has highest electron mobility among known layered magnetic materials

All the elements are there to begin with, so to speak; it's just a matter of figuring out what they are capable of—alone or together. For Leslie Schoop's lab, one recent such investigation has uncovered a layered compound with a trio of properties not previously known to exist in one material.

Coronavirus outbreak raises question: Why are bat viruses so deadly?

It's no coincidence that some of the worst viral disease outbreaks in recent years—SARS, MERS, Ebola, Marburg and likely the newly arrived 2019-nCoV virus—originated in bats.

New process for preserving lumber could offer advantages over pressure treating

Pressure treating—which involves putting lumber inside a pressurized watertight tank and forcing chemicals into the boards—has been used for more than a century to help stave off the fungus that causes wood rot in wet environments.

Quantum memories entangled over 50-kilometer cable

A team of researchers affiliated with several institutions in China has succeeded in sending entangled quantum memories over a 50-kilometer coiled fiber cable. In their paper published in the journal Nature, the group describes several experiments they conducted involving entangling quantum memory over long distances, the challenges they overcame, and problems still to be addressed.

Ancient Antarctic ice melt increased sea levels by 3+ meters—and it could happen again

Rising ocean temperatures drove the melting of Antarctic ice sheets and caused extreme sea level rise more than 100,000 years ago, a new international study led by UNSW Sydney shows.
