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.

Cancer control: Non-DNA changes induce metabolism variations in hepatocellular carcinomas
Mechanisms underlying metabolic variations in hepatocellular carcinoma (HCC), a fast growing and invasive cancer, remain unclear. Now, researchers from Fudan University, China identified signatures of ''m6A,'' the most abundant ''post-transcriptional RNA modification,'' that segregate HCC into sub-types with distinct metabolic characteristics. They have also developed a novel m6A score that can quantify such modifications and aid risk assessment, prediction of prognosis, and response to treatment in patients with HCC. (2021-02-22)

Hydrogen-producing enzyme protects itself against oxygen
Hydrogen-producing enzymes are beacons of hope in biohydrogen research. However, they are so vulnerable to oxygen in the air that it has not been possible to exploit their potential on a larger scale.

They have now overcome this problem in a publication in the current issue of the European Physical Journal C. (2021-02-01)

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.

Transients and synchronization are unified in ecological networks
A new synchronization phenomenon is uncovered in spatially distributed ecological networks. The local patch dynamics are of the chaotic predator-prey type and the network possess certain symmetries in its structure. It is found that the populations of all patches are synchronized in phase but certain subsets of patches can also synchronize in amplitude. During the course of evolution, the subsets of amplitude synchronized patches switch randomly and intermittently among different patterns in a transient fashion. (2020-12-19)

Corporations directing our attention online more than we realize
It's still easy to think we're in control when browsing the internet, but a new study argues much of that is ''an illusion.'' Corporations are ''nudging'' us online more than we realize, and often in hidden ways. Researchers analyzed clickstream data on a million people over one month of internet use to find common browsing sequences, then connected that with site and platform ownership and partnerships, as well as site design and other factors.

Researchers deconstruct the "biological clock" that regulates birdsong
The precise timing of a bird's complex song is driven in part by the often-ignored ''wires'' connecting neurons in the bird's brain, according to a new study. A team of researchers from Penn State and New York University has deconstructed an important ''biological clock'' that regulates birdsong and other behaviors, leading to new ways of thinking about the function of neuronal networks. (2020-10-15)

The puzzle of the strange galaxy made of 99.9% dark matter is solved
At present, the formation of galaxies is difficult to understand without the presence of a ubiquitous, but mysterious component, termed dark matter. Astronomers have measure how much dark matter there is around galaxies, and have found that it varies between 10 and 300 times the quantity of visible matter. However, a few years ago, the discovery of a very diffuse object, named Dragonfly 44, changed this view. (2020-10-13)
