May Day: How electricity brought power to strikes

Areas in Sweden with early access to electricity at the start of the 1900s underwent rapid change. Electrification led to more strikes, but it was not those who were threatened by the new technology who protested. Instead, it was the professional groups who had acquired a stronger negotiating position - thanks to technological development, according to new research from Lund University. Labour market conditions are affected by new technology. Currently, the impact of automation on the labour market is often discussed, whether jobs will disappear as computers take over, or whether digitalisation drives development towards a gig economy with uncertain employment conditions. One fear is that the technological development could generate social unrest and a risk of increased ...

Measuring the Moon's nano dust is no small matter

Like a chameleon of the night sky, the Moon often changes its appearance. It might look larger, brighter or redder, for example, due to its phases, its position in the solar system or smoke in Earth's atmosphere. (It is not made of green cheese, however.) Another factor in its appearance is the size and shape of moon dust particles, the small rock grains that cover the moon's surface. Researchers at the National Institute of Standards and Technology (NIST) are now measuring tinier moon dust particles than ever before, a step toward more precisely explaining the Moon's apparent color ...

New method might improve prostate cancer and high cholesterol treatments

Researchers from the University of Copenhagen, in collaboration with their Swiss colleagues at the University Hospital of Bern, have cracked the code for controlling a group of enzymes that affect our metabolism. The researchers' findings could help us avoid diseases ranging from high cholesterol to infertility to certain types of cancer, which are all due, among other things, to hormonal imbalances. They have found a way to influence a special protein called cytochrome P450 reductase (POR) -- popularly characterized as the 'conductor' of the body's protein orchestra, which helps regulate our hormones and makes it possible to break down medicinal products in the liver. "We have developed a method to ...

How can we stop mankind from stagnating?

Fast growth of the global human population has long been regarded as a major challenge that faces mankind. Presently, this challenge is becoming even more serious than before, in particular because many natural resources are estimated to deplete before the end of this century. The increasing population pressure on agriculture and ecosystems and the environment more generally is predicted to result in worldwide food and water shortages, pollution, lack of housing, poverty and social tension. The situation is exacerbated by global climate change as considerable areas of land are predicted to be flooded and hence taken out of human's use. It is widely believed ...

Socioeconomic deprivation modifies genetic influence on higher education

A comprehensive study from Uppsala University demonstrates that socioeconomic deprivation modifies genetic effects on higher education and abstract reasoning. The paper illustrates how genes play a greater role in educational attainment in more socioeconomically deprived regions of the United Kingdom. The study was recently published in the American Journal of Psychiatry. Education is an important factor in an individual's life and strongly linked to economic outcomes and quality of life. The likelihood of completing higher education is partly determined by genetic factors. Common genetic variants have previously been estimated to contribute 11-13% ...

New model may explain the mystery of asymmetry in Parkinson's disease

Amsterdam, April 28, 2021 - Parkinson's disease (PD) is characterized by slowness of movement and tremors, which often appear asymmetrically in patients. The new model of PD described in this review article published in the Journal of Parkinson's Disease may explain these perplexing asymmetrical motor symptoms and other known variations such as different degrees of constipation and sleep disorders. PD is a heterogenous disorder. Symptoms and the speed with which symptoms progress vary greatly among patients. In three-quarters of patients, motor symptoms initially appear in one side of the body. Some ...

A path to graphene topological qubits

In the quantum realm, electrons can group together to behave in interesting ways. Magnetism is one of these behaviors that we see in our day-to-day life, as is the rarer phenomena of superconductivity. Intriguingly, these two behaviors are often antagonists, meaning that the existence of one of them often destroys the other. However, if these two opposite quantum states are forced to coexist artificially, an elusive state called a topological superconductor appears, which is exciting for researchers trying to make topological qubits. Topological qubits are exciting as one of the potential technologies for future quantum computers. In particular, topological qubits provide the basis for topological quantum ...

New algorithm makes it easier for computers to solve decision making problems

Computer scientists often encounter problems relevant to real-life scenarios. For instance, "multiagent problems," a category characterized by multi-stage decision-making by multiple decision makers or "agents," has relevant applications in search-and-rescue missions, firefighting, and emergency response. Multiagent problems are often solved using a machine learning technique known as "reinforcement learning" (RL), which concerns itself with how intelligent agents make decisions in an environment unfamiliar to them. An approach usually adopted in such an endeavor is policy iteration (PI), which starts off with a "base policy" and then improves on it to generate a "rollout policy" (with the process of generation ...

Spring forest flowers likely key to bumble bee survival, Illinois study finds

CHAMPAIGN, Ill. -- For more than a decade, ecologists have been warning of a downward trend in bumble bee populations across North America, with habitat destruction a primary culprit in those losses. While efforts to preserve wild bees in the Midwest often focus on restoring native flowers to prairies, a new Illinois-based study finds evidence of a steady decline in the availability of springtime flowers in wooded landscapes. The scarcity of early season flowers in forests - a primary food source for bumble bees at this time of year - likely endangers ...

How behavioral rhythms are fine-tuned in the brain

Our bodies and behaviors often seem to have rhythms of their own. Why do we go to the bathroom at the same time every day? Why do we feel off if we can't go to sleep at the right time? Circadian rhythms are a behind-the-scenes force that shape many of our behaviors and our health. Michihiro Mieda and his team at Kanazawa University in Japan are researching how the brain's circadian rhythm control center regulates behavior. Termed the superchiasmatic nucleus, or SCN, the control center contains many types of neurons that transmit signals using the molecule GABA, but little is known about how each type contributes to our bodily rhythms. In their newest study, the researchers focused on GABA neurons that produce arginine vasopressin, a hormone that regulates ...

Causes of extreme weather and climate events in China during 2020/21

During the summer of 2020, especially June and July, periods of extreme heavy rainfall occurred in China's Yangtze River Valley (YRV). These rain events caused the severest floods for the region since the summer of 1998. Despite this, the 2020 western North Pacific (WNP) typhoon season started slowly, but eventually produced 23 named tropical cyclones, still slightly below 27, the WNP seasonal average. As summer transitioned to winter, three severe cold surges swept most parts of China during late 2020 and early 2021, prompting the National Meteorological Center to issue its highest cold surge warning alert ...

Restricting internet searches causes stock market instability: study

The research by RMIT University looked at the ramifications on the stock market following Google's withdrawal from mainland China in 2010. It found access to unbiased information about companies' performance - aided by unrestricted internet search results - led to investors making more informed decisions. On the flip side, search results manipulated to show overly positive information led to stocks for those companies being overvalued temporarily, increasing the stock market crash risk by 19%. The study has been published in the Journal of Financial Economics. Lead researcher Dr Gaoping Zheng, a lecturer in finance at RMIT, said the study showed search results influenced decisions, a challenge to previous thinking that they merely justified people's existing ideas.

Early MR scans found more people with broken-heart syndrome

In almost ten per cent of myocardial infarctions, no obvious cause in the coronary artery can be found. Some of the patients are diagnosed with broken-heart syndrome, while others are left without a diagnosis. A new study from Karolinska Institutet in Sweden suggests that early magnetic resonance (MR) imaging of the heart can greatly increase the rate of diagnosis. The study has been published in the journal JACC Cardiovascular Imaging. Myocardial infarction is one of the most common diseases in the West, and is usually caused by a blood clot that blocks the coronary artery on the heart's surface. However, in up to ten per cent of all myocardial infarctions, no obvious cause ...
