Binary stars are all around us, new map of solar neighborhood shows
A UC Berkeley doctoral student has mined the most recent Gaia survey for all binary stars near Earth and created a 3D atlas of 1.3 million of them. The last local survey included about 200 binary pairs. With such census data, astronomers can conduct statistical analyses on binary populations. For pairs that contain white dwarfs, it's possible to determine the age of their main-sequence companion, and thus of any exoplanets around them. (2021-02-22)

BU researchers identify biochemical process responsible for producing toxic tau
Tau is a protein that helps stabilize the internal skeleton of nerve cells (neurons) in the brain. Groups of toxic tau protein, termed tau oligomers, drive disease progression and memory loss in Alzheimer's disease (AD). A new study from Boston University School of Medicine (BUSM) shows how these tau oligomers form, and, correspondingly, how they can be prevented. (2021-02-22)

Combination of pine scent and ozone as super source of particulate emissions

Climate research: rapid formation of iodic particles over the Arctic
When sea ice melts and the water surface increases, more iodine-containing vapours rise from the sea. Scientists from the international research network CLOUD have now discovered that aerosol particles form rapidly from iodine vapours, which can serve as condensation nuclei for cloud formation. The CLOUD researchers, among them scientists from the Goethe University Frankfurt, fear a mutual intensification of sea ice melt and cloud formation, which could accelerate the warming of the Arctic and Antarctic. (2021-02-11)

No new mountains formed during Earth's middle age, halting life's evolution for an eon
During the Proterozoic, Earth grew no taller - the tectonic processes that form mountains stalled, leaving continents devoid of high mountains for nearly 1 billion years, according to a new study. (2021-02-11)

A new method to search for potentially habitable planets
Imaging planets orbiting around nearby stars, which could potentially harbour life, has become a possibility thanks to the progress made in observational methods by an international team of astronomers, including Olivier Absil and Anne-Lise Maire, astrophysicists at the STAR Institute of ULiège. First candidate: Alpha Centauri, a system similar to ours, ''only'' 4.3 light years away. This study is the subject of a publication in the journal Nature Communications. (2021-02-10)

How the 3-D structure of eye-lens proteins is formed
Chemical bonds within the eye-lens protein gamma-B crystallin hold the protein together and are therefore important for the function of the protein within the lens. Contrary to previous assumptions, some of these bonds, called disulphide bridges, are already formed simultaneously with the synthesis of the protein in the cell. This is what scientists at Goethe University Frankfurt, Max Planck Institute of Biophysics and the French Institute de Biologie Structurale in Grenoble have discovered. (2021-02-10)

Embry-Riddle alumna helps unravel key mysteries of rare stars
Researchers including recent Embry-Riddle Aeronautical University graduate Laura M. Lee have mapped an elderly star's orbit around its oversized and equally ancient partner. In a scientific first, they have also determined the dynamical mass of both stars that make up a binary system called Wolf-Rayet 133. The team's findings, published Feb. 9, 2021 by Astrophysical Journal Letters, mark the first-ever visually observed orbit of a rare type of star called a Nitrogen-rich Wolf-Rayet (WN) star. (2021-02-09)

Study of supergiant star Betelgeuse unveils the cause of its pulsations
Betelgeuse is normally one of the brightest, most recognizable stars of the winter sky, marking the left shoulder of the constellation Orion. But lately, it has been behaving strangely: an unprecedentedly large drop in its brightness has been observed in early 2020 (Figure 1), which has prompted speculation that Betelgeuse may be about to explode. (2021-02-08)

Meet the Smurfs: A bone metabolism family
Researchers from Osaka University and Ehime University have found that protein Smurf2 can regulate a cellular pathway that affects bone metabolism. Smurf2 can mark certain messenger proteins--specifically those that are part of the bone morphogenetic protein signaling pathway--for destruction to prevent the signals from going out of control. The BMP-induced bone in mice without Smurf2 had higher mass and formation rates. These findings improve our understanding of various bone defects. (2021-02-08)

Rare blast's remains discovered in Milky Way's center
Astronomers may have found our Galaxy's first example of an unusual kind of stellar explosion. This discovery, made with NASA's Chandra X-ray Observatory, adds to the understanding of how some stars shatter and seed the universe with elements critical for life on Earth. (2021-02-08)

Iodine oxoacids drive rapid aerosol formation in pristine atmospheric areas
Iodine plays a bigger role than thought in rapid new particle formation (NPF) in relatively pristine regions of the atmosphere, such as along marine coasts, in the Arctic boundary layer or in the upper free troposphere, according to a new study. (2021-02-04)

The strange impact of the first consumer review
If you're about to buy something online and its only customer review is negative, you'd probably reconsider the purchase, right? It turns out a product's first review can have an outsized effect on the item's future -- it can even cause the product to fail. (2021-02-04)

Supersaturation: The barrier between protein folding and misfolding
It's commonly accepted that protein folding/misfolding are alternative reactions of unfolded proteins but the principles governing this remain unknown. Here, researchers from Osaka University describe a general concept that links protein folding and misfolding: protein folding and amyloid formation are separated by the supersaturation barrier of a denatured protein. Breakdown of this supersaturation barrier is required to shift the protein to the amyloid pathway, linking Anfinsen's intramolecular folding universe with the ''outer'' intermolecular misfolding universe. (2021-02-01)

Astronomers spot bizarre activity from one of the strongest magnets in the Universe
Astronomers from the ARC Centre of Excellence for Gravitational Wave Discovery (OzGrav) and CSIRO have just observed bizarre, never-seen-before behaviour from a 'radio-loud' magnetar--a rare type of neutron star and one of the strongest magnets in the Universe. Their new findings, published today in the Monthly Notices of the Royal Astronomical Society (MNRAS), suggest magnetars have more complex magnetic fields than previously thought - which may challenge theories of how they are born and evolve over time. (2021-02-01)

Local emissions amplify regional haze and particle growth
A Finnish-Chinese research team performed simultaneous measurements of aerosol composition and particle number size distributions at ground level and at 260 m in central Beijing, China, during a total of 4 months in 2015-2017. The team found concentration of both primary and secondary particles in the accumulation mode would decrease drastically, and the haze formation would be reduced if the emission cuts are higher than 30%. (2021-01-29)

High schoolers discover four exoplanets through Harvard and Smithsonian mentorship program
They may be the youngest astronomers to make a discovery yet. This week, 16-year-old Kartik Pinglé and 18-year-old Jasmine Wright have co-authored a peer-reviewed paper in The Astronomical Journal describing the discovery of four new exoplanets about 200-light-years away from Earth. (2021-01-28)
