“Grit in the Gears” Costs Energy in Modular Information Systems

August 16, 2018

Digital information may appear to exist as abstract ones and zeroes, flipping effortlessly from one to another. But in fact there is a minimum amount of energy required to run any computation system, regardless of how “energy efficient” are its component parts.

There and Back Again: Mantle Xenon Has a Story to Tell

August 08, 2018
The Earth has been through a lot of changes in its 4.5 billion year history, including a shift to incorporating and retaining volatile compounds such as water, nitrogen and carbon from the atmosphere in the mantle before spewing them out again through volcanic eruptions.

Markers of Cellular Aging Improve During Insight Meditation Retreat

August 03, 2018
Telomeres, which act as as protective “caps” at the end of DNA strands, tend to shorten as cells age. A recent study by researchers at the UC Davis Center for Mind and Brain found that the average telomere length in immune cells increased instead in individuals who participated in a month-long Insight meditation retreat. This is the first study to show changes in telomere length occurring over such a short time span.

Reversing cause and effect is no trouble for quantum computers

July 20, 2018
In research published 18 July in Physical Review X, an international team shows that a quantum computer is less in thrall to the arrow of time than a classical computer. In some cases, it's as if the quantum computer doesn't need to distinguish between cause and effect at all.

Playing It Cool at Ocean Vents

June 29, 2018
Not all ocean vents are hot. Cool hydrothermal systems, or cool vents, are much harder to spot because the fluids they release are clear and only a bit warmer than surrounding water. Yet they could play a major role in releasing minerals into the deep ocean. Now researchers including Laura Zinke, now a postdoctoral researcher at UC Davis, have published the first survey of the microbes living near a cool vent.

Psychedelic Drugs Change Structure of Neurons

June 12, 2018
A team of scientists at the University of California, Davis, is exploring how hallucinogenic drugs impact the structure and function of neurons — research that could lead to new treatments for depression, anxiety and related disorders.

Curiosity Rover Finds Organic Matter on Mars

June 07, 2018
The Mars Curiosity rover team announced today (June 7) finding organic matter – carbon-based compounds – in three billion year old mudstone sediments from Gale Crater. Dawn Sumner, professor of earth and planetary sciences, is a member of the Mars Curiosity team and coauthor on the first paper.
