I think we should. If it is corrupt or makes mistakes, it will at least be correctable.

LONDON — A study has found that most Europeans would like to see some of their members of parliament replaced by algorithms.

Researchers at IE University’s Center for the Governance of Change asked 2769 people from 11 countries worldwide how they would feel about reducing the number of national parliamentarians in their country and giving those seats to an AI that would have access to their data.

Everything is weird on the Sun, where things are not where you’d expect.

This spike in temperature, despite the increased distance from the Sun’s main energy source, has been observed in most stars and represents a fundamental puzzle that astrophysicists have mulled over for decades.

One hundred fifty years ago, Dmitri Mendeleev created the periodic table, a system for classifying atoms based on the properties of their nuclei. This week, a team of biologists studying the tree of life has unveiled a new classification system for cell nuclei, and discovered a method for transmuting one type of cell nucleus into another.

The study, which appears this week in the journal Science, emerged from several once-separate efforts. One centered on the DNA Zoo, an international consortium spanning dozens of institutions including Baylor College of Medicine, the National Science Foundation-supported Center for Theoretical Biological Physics (CTBP) at Rice University, the University of Western Australia and SeaWorld.

Scientists on the DNA Zoo team had been working together to classify how chromosomes — which can be several meters long — fold up to fit inside the nuclei of different species from across the tree of life.

Weird now, but i do think most people will want humanoid robots faking emotions, to some degree, and on the far end people who will want them to try and mimic people exactly.

Columbia Engineering researchers use AI to teach robots to make appropriate reactive human facial expressions, an ability that could build trust between humans and their robotic co-workers and care-givers. (See video below.)

When scientists first announced that they had read all of a person’s DNA 20 years ago, they were still missing some bits. Now, with the benefit of far better methods for reading DNA, it has finally been possible to read the whole thing from end to end.

Two decades after the first drafts of the human genome were published, new sequencing technologies mean it is finally complete – and could show us more than ever.

Summary: Disruptions in how the body converts cholesterol into bile acids may play a key role in the development of dementia.

Source: PLOS

The blood-brain barrier is impermeable to cholesterol, yet high blood cholesterol is associated with increased risk of Alzheimer’s disease and vascular dementia. However, the underlying mechanisms mediating this relationship are poorly understood.

A series of experiments shows, remarkably, that it just might.

Falling drops usually make a splash, but these drops do the twist. Researchers have created surfaces that can make droplets spin and whirl at more than 7300 revolutions per minute when they rebound.

To make the water droplets spin, researchers first had to make sure they didn’t wet the surface they fell on—otherwise, they’d just splash. The researchers did this by coating alumina plates with a fluorinated nonstick coating, similar to those found in nonstick cooking pans. Next, they masked some regions of the surface and shone ultraviolet (UV) light on the entire plate. The regions exposed to the UV became highly “wettable,” meaning water touching those regions spread out immediately rather than bouncing back up. The team created several designs of the wettable regions, including one with spiral arms radiating out from a center, much like a pinwheel.
