Geoengineering is Just a Partial Solution to Fight Climate Change

Informed 3 weeks ago

Could we create massive sulfuric acid clouds that limit global warming and help meet the 2015 Paris international climate goals, while reducing unintended impacts? Yes, in theory. Spraying sulfur dioxide into the upper atmosphere at different locations, to form sulfuric acid clouds that block some solar radiation, could be adjusted every year to keep global warming at levels set in the Paris goals. Such technology is known as geoengineering or climate intervention.

For university classrooms, are telepresence robots the next best thing to being there?

Informed Wednesday, June 10, 2020 at 09:03:36 AM

Telepresence robots help university students learning remotely to feel more a part of the class, new research by Oregon State University suggests.

The National Science Foundation study led by Naomi Fitter of the OSU College of Engineering examined the experiences of university students attending classes in three formats: in person; through a telepresence robot; and via distance learning tools such as livestreaming, recorded lectures and calling into class with questions.

The preferences of the 18 engineering students who were studied were split between distance learning tools, or DLTs, and attending in person. Instructors of the four courses in the study uniformly preferred teaching students in person.

But the instructors felt telepresence robots were preferable to distance learning tools for remote learning, and the students noted the robots’ ability to keep them more engaged, expressive and self-aware.

New material acts as an efficient frequency multiplier

Informed May 21, 2020 at 05:44 AM

Higher frequencies mean faster data transfer and more powerful processors – the formula that has been driving the IT industry for years. Technically, however, it is anything but easy to keep increasing clock rates and radio frequencies. New materials could solve the problem. Experiments at Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have now produced a promising result: An international team of researchers was able to get a novel material to increase the frequency of a terahertz radiation flash by a factor of seven: a first step for potential IT applications.

A soft touch for robotic hardware

Informed May 17, 2020 at 11:34 AM

Robots can be made from soft materials, but the flexibility of such robots is limited by the inclusion of rigid sensors necessary for their control. Researchers created embedded sensors, to replace rigid sensors, that offer the same functionality but afford the robot greater flexibility. Soft robots can be more adaptable and resilient than more traditional rigid designs. The team used cutting-edge machine learning techniques to create their design.

Blockchain, consent and prosent for medical research

Informed May 12, 2020 at 04:26 AM

Recent advances in medical and information technologies, the availability of new types of medical data, the requirement of increasing numbers of study participants, as well as difficulties in recruitment and retention, all present serious problems for traditional models of specific and informed consent to medical research. However, these advances also enable novel ways to securely share and analyse data. This paper introduces one of these advances—blockchain technologies—and argues that they can be used to share medical data in a secure and auditable fashion. In addition, some aspects of consent and data collection, as well as data access management and analysis, can be automated using blockchain-based smart contracts. This paper demonstrates how blockchain technologies can be used to further all three of the bioethical principles underlying consent requirements: the autonomy of patients, by giving them much greater control over their data; beneficence, by greatly facilitating medical research efficiency and by reducing biases and opportunities for errors; and justice, by enabling patients with rare or under-researched conditions to pseudonymously aggregate their data for analysis.

Artificial chloroplasts turn sunlight and carbon dioxide into organic compounds

Informed May 12, 2020 at 03:59 AM

Just like mechanics cobble together old engine parts to build a new roadster, synthetic biologists have remade chloroplasts, the engine at the heart of photosynthesis. By combining the light-harvesting machinery of spinach plants with enzymes from nine different organisms, scientists report making an artificial chloroplast that operates outside of cells to harvest sunlight and use the resulting energy to convert carbon dioxide (CO2) into energy-rich molecules. The researchers hope their souped-up photosynthesis system might eventually convert CO2 directly into useful chemicals—or help genetically engineered plants absorb up to 10 times the atmospheric CO2 of regular ones.

Hydrogen is an essential commodity with over 60 million tons produced globally every year. However, more than 95% of it is made by steam reformation of fossil fuels, a process that is energy intensive and produces carbon dioxide. If we could replace even a part of that with algal biohydrogen that is made via light and water, it would have a substantial impact.

A closer look at superconductors

Informed May 09, 2020 at 08:34 AM

From sustainable energy to quantum computers: high-temperature superconductors have the potential to revolutionize today’s technologies. Despite intensive research, however, we still lack the necessary basic understanding to develop these complex materials for widespread application. "Higgs spectroscopy" could bring about a watershed as it reveals the dynamics of paired electrons in superconductors. An international research consortium centered around the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and the Max Planck Institute for Solid State Research (MPI-FKF) is now presenting the new measuring method in the journal Nature Communications (DOI: 10.1038/s41467-020-15613-1). Remarkably, the dynamics also reveal typical precursors of superconductivity even above the critical temperature at which the materials investigated attain superconductivity.

Identifying Light Sources Using Artificial Intelligence

Informed May 08, 2020 at 06:29 AM

Identifying sources of light plays an important role in the development of many photonic technologies, such as lidar, remote sensing, and microscopy. Traditionally, identifying light sources as diverse as sunlight, laser radiation, or molecule fluorescence has required millions of measurements, particularly in low-light environments, which limits the realistic implementation of quantum photonic technologies.

Researchers demonstrated a smart quantum technology that enables a dramatic reduction in the number of measurements required to identify light sources.

Superconductivity: It’s Hydrogen’s Fault

Informed Apr 29, 2020 at 02:41 AM

When hydrogen is incorporated into the nickelate structure, it is not a superconductor.

Last summer, a new age for high-temperature superconductivity was proclaimed - the nickel age. It was discovered that there are promising superconductors in a special class of materials, the so-called nickelates, which can conduct electric current without any resistance even at high temperatures.

However, it soon became apparent that these initially spectacular results from Stanford could not be reproduced by other research groups. TU Wien (Vienna) has now found the reason for this: In some nickelates additional hydrogen atoms are incorporated into the material structure. This completely changes the electrical behaviour of the material. In the production of the new superconductors, this effect must now be taken into account.
