Study of auto recalls shows carmakers delay announcements until they 'hide in the herd'
Automotive recalls are occurring at record levels, but seem to be announced after inexplicable delays. A research study of 48 years of auto recalls announced in the United States finds carmakers frequently wait to make their announcements until after a competitor issues a recall - even if it is unrelated to similar defects.

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)

Past earthquakes triggered large rockslides in the Eastern Alps
Geologists from the University of Innsbruck shed new light on a long-lasting debate about the trigger mechanism of large rockslides. Lake mud in two Alpine lakes in Tyrol reveal that rare strong earthquakes are the final cause of multiple, prehistoric rockslides in the Eastern Alps. The steep rock slopes were degraded by a series of prehistoric earthquakes, larger than any of the historically documented events in the region of the past ~1000 years. The study has now been published in the Journal Nature Communications. (2021-02-16)

How metal atoms can arrange themselves on an insulator
In order to produce tiny electronic memories or sensors in future, it is essential to be able to arrange individual metal atoms on an insulating layer. Scientists at Bielefeld University's Faculty of Chemistry have now demonstrated that this is possible at room temperature: molecules of the metal-containing compound molybdenum acetate form an ordered structure on the insulator calcite without jumping to other positions or rotating. Their findings have been presented in the Nature Communications journal. (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)

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.

Precision measurements of intracluster light suggest possible link to dark matter
Faint light from rogue stars not bound to galaxies has been something of a mystery to scientists. The dimness of this intracluster light makes it difficult to measure, and no one knows how much there is. Scientists on the Dark Energy Survey, led by Fermilab, have made the most radially extended measurement of this light ever, and they've found that its distribution might point to the distribution of dark matter. (2021-01-27)
