Best predictor of arrest rates? The 'birth lottery of history'

2021-05-21
Social scientists have had a longstanding fixation on moral character, demographic information, and socioeconomic status when it comes to analyzing crime and arrest rates. The measures have become traditional markers used to quantify and predict criminalization, but they leave out a crucial indicator: what's going on in the changing world around their subjects. An unprecedented longitudinal study, published today in the American Journal of Sociology, looks to make that story more complete and show that when it comes to arrests it can come down to when someone is rather than who someone is, a theory the researchers refer to as the birth lottery of history. Harvard sociologist Robert J. Sampson and Ph.D. candidate Roland Neil followed arrests in the lives of more than ...

Pandemic paleo: A wayward skull, at-home fossil analyses, a first for Antarctic amphibians

Pandemic paleo: A wayward skull, at-home fossil analyses, a first for Antarctic amphibians
2021-05-21
Paleontologists had to adjust to stay safe during the COVID-19 pandemic. Many had to postpone fossil excavations, temporarily close museums and teach the next generation of fossil hunters virtually instead of in person. But at least parts of the show could go on during the pandemic -- with some significant changes. "For paleontologists, going into the field to look for fossils is where data collection begins, but it does not end there," said Christian Sidor, a University of Washington professor of biology and curator of vertebrate paleontology ...

Researchers develop advanced model to improve safety of next-generation reactors

Researchers develop advanced model to improve safety of next-generation reactors
2021-05-21
When one of the largest modern earthquakes struck Japan on March 11, 2011, the nuclear reactors at Fukushima-Daiichi automatically shut down, as designed. The emergency systems, which would have helped maintain the necessary cooling of the core, were destroyed by the subsequent tsunami. Because the reactor could no longer cool itself, the core overheated, resulting in a severe nuclear meltdown, the likes of which haven't been seen since the Chernobyl disaster in 1986. Since then, reactors have improved exponentially in terms of safety, sustainability and efficiency. Unlike the light-water reactors at Fukushima, which had liquid coolant and uranium ...

Finding the first flower from Northwest China

Finding the first flower from Northwest China
2021-05-21
"Abominable mystery" -- the early origin and evolution of angiosperms (flowering plants) was such described by Charles Robert Darwin. So far, we still have not completely solved the problem, and do not know how the earth evolved into such a colorful and blooming world. Recently, a new angiosperm was reported based on numerous exceptionally well-preserved fossils from the Lower Cretaceous of Jiuquan Basin, West Gansu Province, Northwest China. The new discovery is the earliest and unique record of early angiosperms in Northwest China. The study has been accepted for publication in the journal National Science Review and is currently available online at https://doi.org/10.1093/nsr/nwab084. The new angiosperm was named Gansufructus saligna, and all the fossil specimens ...

Russian wildfires and tropospheric ozone pollution over Northern Tibetan Plateau

Russian wildfires and tropospheric ozone pollution over Northern Tibetan Plateau
2021-05-21
Atmospheric ozone, which can regulate the amount of incoming ultraviolet radiation on the Earth's surface, is important for the atmospheric environment and ecosystems. Tropospheric ozone, primarily originating from photochemical reactions, is the third most prominent greenhouse gas causing climate warming. A research team led by Dr. Jinqiang Zhang from the Institute of Atmospheric Physics (IAP) of the Chinese Academy of Sciences tried to analyze vertical ozone distributions and explore the influence of deep stratospheric intrusions and wildfires on ozone variation in the northern Tibetan Plateau (TP) during the Asian summer monsoon period. Their findings were published in Atmospheric Research. Ozone variation over the TP can influence weather and climate change. ...

New method of seeing graphene growing using a standard electron microscope

2021-05-21
Researchers from the University of Surrey have revealed a new method that enables common laboratory scanning electron microscopes to see graphene growing over a microchip surface in real time. This discovery, published in ACS Applied Nano Materials, could create a path to control the growth of graphene in production factories and lead to the reliable production of graphene layers. Dispensing with the use of expensive bespoke systems, the new technique not only produces graphene sheets reliably but also allows to use fast-acting catalysts that reduce growth times from several hours to only a few minutes. With the use of video imagining, the team from Surrey's Advanced Technology Institute (ATI) have shown graphene growing over an iron catalyst, using a silicon nitride ...

Whos in this ocean? Tracking down species on the go using environmental DNA
2021-05-21
Sloughed off skin and bodily fluids are things most people would prefer to avoid. But for marine biologist like Cheryl Lewis Ames, Associate Professor of Applied Marine Biology in the Graduate School of Agricultural Science at Tohoku University (Japan), such remnants of life have become a magical key to detecting the unseen. Any organism living in the ocean will inevitably leave behind traces containing their DNA - environmental DNA (eDNA) - detectable in water samples collected from the ocean Only recently has molecular sequencing technology become ...

Missing role of finance in climate mitigation scenarios

2021-05-21
Researchers at the University of Zurich show how climate mitigation scenarios can be improved by taking into account that the financial system can play both an enabling or a hampering role on the path to a sustainable economic system. To limit global warming, a profound transformation of energy, production and consumption in our economies is required. The scale of the transformation means that the financial system must have a proactive role. New green investments are needed, as well as a reallocation of capital from high to low-carbon activities. The Central Banks and Supervisors Network for Greening the Financial ...

A new spintronic phenomenon: Chiral-spin rotation found in non-collinear antiferromagnet

A new spintronic phenomenon: Chiral-spin rotation found in non-collinear antiferromagnet
2021-05-21
Researchers at Tohoku University and the Japan Atomic Energy Agency (JAEA) have discovered a new spintronic phenomenon - a persistent rotation of chiral-spin structure. Their discovery was published in the journal Nature Materials on May 13, 2021. Tohoku University and JAEA researchers studied the response of chiral-spin structure of a non-collinear antiferromagnet Mn3Sn thin film to electron spin injection and found that the chiral-spin structure shows persistent rotation at zero magnetic field. Moreover, their frequency can be tuned by the applied current. "The electrical control of magnetic ...

Infants recognize rapid images, just like adults

Infants recognize rapid images, just like adults
2021-05-21
It has previously been reported that human visual system has a temporal limitation in processing visual information when perceiving things that occur less than half a second apart. This temporal deficit is known as "attentional blink" and has been demonstrated in a large number of studies. These studies reported that adults could recognize two things when these two were temporally separated over 500 ms, but adults overlooked the second thing when the temporal interval was less than 500 ms. Recently, this attentional blink phenomenon has been observed in even preverbal infants less than one-year old. In the study ...

Researchers identify a gene that causes canine hereditary deafness in puppies

2021-05-21
Finnish researchers have been the first to determine the cause for the nonsyndromic early-onset hereditary canine hearing loss in Rottweilers. The gene defect was identified in a gene relevant to the sense of hearing. The study can also promote the understanding of mechanisms of hearing loss in human. Hearing loss is the most common sensory impairment and a complex problem in humans, with varying causes, severity and age of onset. Deafness and hearing loss are fairly common also in dogs, but gene variants underlying the hereditary form of the disorder are so far poorly ...

NIST, collaborators develop new method to better study microscopic plastics in the ocean

NIST, collaborators develop new method to better study microscopic plastics in the ocean
2021-05-21
If you've been to your local beach, you may have noticed the wind tossing around litter such as an empty potato chip bag or a plastic straw. These plastics often make their way into the ocean, affecting not only marine life and the environment but also threatening food safety and human health. Eventually, many of these plastics break down into microscopic sizes, making it hard for scientists to quantify and measure them. Researchers call these incredibly small fragments "nanoplastics" and "microplastics" because they are not visible to the naked eye. Now, in a multiorganizational effort led by the National Institute of Standards and ...

Just half a degree Celsius less warming would save economic losses of Chinese railway infrastructure by approximately $0.63 billion per year, according to a new paper published by a collaborative research team based in Beijing Normal University and the Institute of Atmospheric Physics, Chinese Academy of Sciences, China. The study, which appears in Transportation Research Part D recently, found that the rainfall-induced disaster risk of railway infrastructure has increased with increasing extreme rainfall days during the decades 1981-2016. Limiting global ...

Legitimation strategies for coal exits in Germany and Canada

2021-05-21
Ending our dependence on coal is essential for effective climate protection. Nevertheless, efforts to phase out coal trigger anxiety and resistance, particularly in mining regions. The governments of both Canada and Germany have involved various stakeholders to develop recommendations aimed at delivering just transitions and guiding structural change. In a new study, researchers at the Institute for Advanced Sustainability Studies (IASS) compare the stakeholder commissions convened by the two countries, drawing on expert interviews with their members, and examine how governments use commissions to legitimize their transition policies. In the study, the researchers identify similarities and ...

The work, carried out by Pilar Madrigal and Sandra Jurado, from the UMH-CSIC Neurosciences Institute in Alicante, a joint center of the Spanish National Research Council and Miguel Hernández University, has been published in Communications Biology, a Nature group´s journal. "Our in-depth analysis of the oxytocin-vasopressin circuit in the mouse brain has revealed that these two molecules have distinct dynamics throughout embryonic development. It is likely that these adaptations modulate the functional properties of different brain regions according to their developmental stage, contributing to the refinement ...

Device for detection of signs of sudden cardiac death developed at TPU

2021-05-21
Scientists of Tomsk Polytechnic University have developed a nanosensor-based hardware and software complex for measurement of cardiac micropotential energies without filtering and averaging-out cardiac cycles in real time. The device allows registering early abnormalities in the function of cardiac muscle cells, which otherwise can be recorded only during open-heart surgery or by inserting an electrode in a cardiac cavity through a vein. Such changes can lead to sudden cardiac death (SCD). Nowadays, there are no alternatives to the Tomsk device for a number of key characteristics in Russia and the world. The research findings of four-year measurement of cardiac micropotential energies using this device ...

Chirality memory effect of ferromagnetic domain walls

Chirality memory effect of ferromagnetic domain walls
2021-05-21
Using magnets, a collaborative group have furthered our understanding of chirality. Their research was published in the journal Physical Review Letters on April 28, 2021. Chirality is the lack of symmetry in matter. Human hands, for example, express chirality. A mirror image of your right hand differs from your left, giving it two distinguishable chiral states. Chirality is an important issue in a myriad of scientific fields, ranging from high-energy physics to biology. Within our bodies, some molecules, such as amino acids, show only one chiral state. In other words, they are homo-chiral. It is crucial to understand how this information is transferred and ...

Type 2 diabetes medication shown to benefit asthma patients

Type 2 diabetes medication shown to benefit asthma patients
2021-05-21
Type 2 diabetes patients who also have asthma are benefitting from a diabetes medication, typically given to help the pancreas produce more insulin, that also improves asthma symptoms and may reduce lung and airway inflammation. These types of medication -- GLP-1 receptor agonists -- are a newer class of FDA-approved therapeutics that are generally used in addition to metformin for control of blood sugar or to induce weight loss in patients with obesity. Researchers from Vanderbilt University Medical Center, Brigham and Women's Hospital, Harvard Medical School and University Hospital Zurich in Switzerland used electronic health record (EHR) data of patients with asthma and type 2 diabetes who initiated treatment with GLP-1R agonists, finding lower rates of asthma exacerbations ...

Face masks effectively limit SARS-CoV-2 transmission

2021-05-21
'Don't forget the mask' - although most people nowadays follow this advice, professionals express different opinions about the effectiveness of face masks. An international team led by researchers from the Max Planck Institute for Chemistry in Mainz, Germany, has now used observational data and model calculations to answer open questions. The study shows under which conditions and in which way masks actually reduce individual and population-average risks of being infected with COVID-19 and help mitigate the corona pandemic. In most environments and situations, ...

Penn doubles the percentage of Black participants in cancer clinical trials

2021-05-21
PHILADELPHIA--A five-year community outreach and engagement effort by the Abramson Cancer Center at the University of Pennsylvania (ACC) to increase enrollment of Black patients into cancer clinical trials more than doubled the percentage of participants, improving access and treatment for a group with historically low representation in cancer research. The percentage of patients enrolled into a treatment clinical trial, for example, increased from 12 to 24 percent. A significant increase was also observed in non-therapeutic interventional and non-interventional trials. The findings were published today in an abstract to be presented at the American Society of Clinical Oncology annual meeting on June 5. (Abstract #100). [ADD ...

In utero exposure to tiny air pollution particles is linked to asthma in preschoolers

2021-05-21
New York, NY (May 21, 2021) --Women who were highly exposed to ultra-fine particles in air pollution during their pregnancy were more likely to have children who developed asthma, according to a study published in the American Journal of Respiratory and Critical Care Medicine in May. This is the first time asthma has been linked with prenatal exposure to this type of air pollution, which is named for its tiny size and which is not regulated or routinely monitored in the United States. Slightly more than 18 percent of the children born to these mothers developed asthma in their preschool years, compared ...

A novel defense mechanism for SARS-CoV-2 discovered

A novel defense mechanism for SARS-CoV-2 discovered
2021-05-21
Scientists from Hokkaido University have discovered a novel defensive response to SARS-CoV-2 that involves the viral pattern recognition receptor RIG-I. Upregulating expression of this protein could strengthen the immune response in COPD patients. In the 18 months since the first report of COVID-19 and the spread of the pandemic, there has been a large amount of research into understanding it and developing menas to treat it. COVID-19 does not affect all infected individuals equally. Many individuals are asymptomatic; of those who are symptomatic, the large majority have mild symptoms, and only a small number have severe cases. The reasons for this are not fully understood and are an important area of ongoing research. A team of scientists ...

A tripartite-chromosome E. coli strain allows the chromosome isolation and implantation

A tripartite-chromosome E. coli strain allows the chromosome isolation and implantation
2021-05-21
The issue of concern was that the Escherichia coli (E. coli) genome, consisting of 4.6 million base pairs of a single circular DNA, is too large to manipulate following the extraction and transfer to other bacteria. In the present study, a group of Rikkyo University researchers led by Assistant Professor Takahito Mukai and Professor Masayuki Su'etsugu has succeeded in splitting the E.coli genome into tripartite-genome of 1 million base pairs per genome (split-genome) using the smallest E. coli genome strain established so far. In addition, they successfully extracted the split-genome from bacteria and installed it in other E. ...

Telling up from down: How marine flatworms learn to sense gravity

Telling up from down: How marine flatworms learn to sense gravity
2021-05-21
All living organisms are equipped with sensory organs to detect changes in their surrounding environment. It may not immediately strike us as obvious but, similar to how we can sense heat, cold, light, and darkness, we are also extremely adept at sensing gravity. In our case, it is our inner ear that does this job, helping us maintain balance, posture, and orientation in space. But, what about other organisms, for instance invertebrates that lack a backbone? The gravity sensing organ in some aquatic invertebrates, known as a "statocyst," is, in fact, rather fascinating. The statocyst is essentially a fluid-filled sac with sensory cells lining its inner wall and a small, mineralized ...
