Machine Learning for Magnetics – Eos

Interpretation of (aero)magnetic anomaly maps typically involves a series of steps after optimization of raw flight data. Nurindrawati and Sun [2020] explore the performance of machine learning methods for this kind of problem. They test various sets of convolutional neural networks (CNN) and train the two optimal CNN designs (one for declination and […]

It’s about time adults start rising up against climate change

The planet being left to today’s youth is hurting, and it’s all of our job to heal it. (Shadia Fayne Wood, 350.org /) The following is an excerpt from All We Can Save: Truth, Courage, and Solutions for the Climate Crisis, an anthology of provocative and illuminating writing by women at the forefront of the […]

High flavanol diet may lead to lower blood pressure

People who consume a diet including flavanol-rich foods and drinks, including tea, apples and berries, could lead to lower blood pressure, according to the first study using objective measures of thousands of UK residents’ diet. The findings, published in Scientific Reports, studied the diet of more than 25,000 people in Norfolk, UK and compared what […]

Material found in paint may hold the key to a technological revolution

The waste chips of paint you strip off the walls might not be so useless afterall. Image credit: Sandia National Laboratories For the next generation of computer processors, one persistent challenge for researchers is finding novel ways to make non-volatile memory on an ever-smaller scale. As smaller processors inevitably lead toward a finite limit on […]

Current Chernobyl-level radiation harmful to bees: study

Colony reproduction reduced by 30 to 45 percent at radiation doses previously considered too low to impact insects Bumblebees exposed to levels of radiation found within the Chernobyl exclusion zone suffered a “significant” drop in reproduction, in new research published Wednesday that scientists say should prompt a rethink of international calculations of nuclear environmental risk. […]

The very first forms of life may have been more animal-like than we ever realized

Early life may have been far more like animals than we thought, suggests new research that shows bacteria can ‘develop’ like an embryo. When bacteria band together, they ooze out a protective communal home of slime to form thriving, densely packed colonies known as biofilms. Together these teeny organisms are more powerful. Within the safety […]

Repairing the photosynthetic enzyme Rubisco — ScienceDaily

Manajit Hayer-Hartl, head of the research group “Chaperonin-assisted Protein Folding,” has a long-standing interest in the central enzyme of photosynthesis called Rubisco. Her team has already reported on many of the interacting partners of Rubisco that are required for the folding and assembly of this highly abundant protein. In the current study, they have elucidated […]

Community noise may affect dementia risk

Results from a new study published in Alzheimer’s & Dementia support emerging evidence suggesting that noise may influence individuals’ risk of developing dementia later in life. Researchers studied 5,227 participants of the Chicago Health and Aging Project who were aged 65 years or older, of whom 30% had mild cognitive impairment and 11% had Alzheimer’s […]

Is there long-term immunity for SARS-CoV-2?

SARS-CoV-2 antibodies provide lasting immunity, say UArizona Health Sciences researchers. SEM image of SARS-CoV-2 (round gold objects) emerging from the surface of cells cultured in the lab.

Air pollution costs Europe cities $190bn a year: analysis

Air pollution increases the likelihood of developing conditions that are known risk factors for Covid-19, the report said Air pollution costs inhabitants of European cities more than 160 billion euros ($190 billion) each year due to long- and short-term health impacts, a group of environmental and social watchdogs said in research published Wednesday. In a […]
