Researchers at Imperial College London have developed a model to determine the lifetime costs of 9 electricity storage technologies for 12 different applications between 2015 and 2050. The model, which predicts lithium-ion batteries to be the cheapest technology in the coming decades, appears Jan. 9 in the journal Joule, and is available open access.
Microscopic marine plants flourish beneath the ice that covers the Greenland Sea, according to a new study in the Journal of Geophysical Research: Oceans. These phytoplankton create the energy that fuels ocean ecosystems, and the study found that half of this energy is produced under the sea ice in late winter and early spring, and the other half at the edge of the ice in spring.
Gaps in the logic of how we restock flu vaccines may be costing hundreds of lives, or more. A new model to tweak the gaps could save hundreds to hundreds-of-thousands of people and millions to multiple millions of dollars in medical costs.
In a study published in Physical Review E, physicists analyzed the Rossler system, a well-known chaotic system which physicists have studied thoroughly for almost 40 years. Looking at this system from a fresh perspective, they discovered new phenomena that have been overlooked until now. For the first time the researchers were able to measure the fine grain process that leads from disorder to synchrony, discovering a new kind of synchronization between chaotic systems.
Why is water densest at around 4 degrees Celsius? Why does ice float? Why heavy water has a different melting point compared to normal water? Why do snowflakes have a six-fold symmetry? A collaborative study, led by researchers in EPFL and just published in the Proceedings of the National Academy of Sciences, provides physical insights into these questions by marrying data-driven machine learning techniques and quantum mechanics.
A novel new way of determining the value of employee stock options has yielded some surprising insights: Options granted to woman and senior managers are worth more because they hold them longer. And options that vest annually rather than monthly are worth more for the same reason.
Researchers at MIT and Arizona State University have designed a computer program that allows users to translate any free-form drawing into a two-dimensional, nanoscale structure made of DNA.
The majority of deaths during the single largest murder campaign of the Holocaust, called Operation Reinhard, occurred during a single three-month period, a new study reveals. Not only does this study indicate that the murder rate during Operation Reinhard has previously been greatly underestimated, it also provides new insights into the profound efficiency of Nazi death camps and the systematic manner in which Jewish communities were murdered.
People make statistically-informed judgments about who is more likely to hold particular professions even though they criticize others for the same behavior, according to findings published in Psychological Science, a journal of the Association for Psychological Science.
In a paper published Jan. 2 in PLOS Biology, two scientists at the University of Washington and North Carolina State University use the economic theory of contests to illustrate how the competitive grant-application system has made the pursuit of research funding inefficient and unsustainable -- and that alternative methods, such as a partial lottery to award grants, could relieve pressure on professors and free up time for research.
