Natural gas supplies 32% of all primary energy in the United States, its share of electricity generation having nearly doubled from 2008 to 2021. The cross-country natural gas pipeline system used to be powered mainly by natural gas, but recently has switched in places to electric power. The natural gas pipeline system has generally been much more reliable than the electric power system. The new dependence on electricity has created a vulnerability during hurricanes and other events that can take out electric power, since lack of natural gas may in turn cause gas-powered electric ...

Researchers at Baylor College of Medicine and collaborating institutions report in the journal Nature Communications how a mutation in the enzyme SKD3 can cause a form of a genetic disease known as 3-methylglutaconic aciduria (MGCA7). MGCA7 is an inborn error of metabolism associated with variable neurologic deficits and an abnormally low number of immune cells called neutrophils in the blood. The latter condition, known as neutropenia, can lead to increased susceptibility to infection and can also develop into leukemia, as well as early death in infants. “SKD3 is essential to protein quality control in animal cells. It removes damaged proteins in structures or organelles ...

Key Takeaways: Consumers differ in the way that they shop: some “showroom” by figuring out what they want at one kind of retail outlet and buying elsewhere; others conduct deep research and buy where they first find what they like; and other kinds of consumers are less particular and conduct only fairly limited research. Consumers who are less choosy may shop at stores that have fewer selections, as long as they can pay a lower price for what they buy. This is the one group of consumers most likely to influence price.   BALTIMORE, MD, April 11, 2023 – It’s ...

WASHINGTON — Researchers have developed a new chip-sized microwave photonic filter to separate communication signals from noise and suppress unwanted interference across the full radio frequency spectrum. The device is expected to help next-generation wireless communication technologies efficiently convey data in an environment that is becoming crowded with signals from devices such as cell phones, self-driving vehicles, internet-connected appliances and smart city infrastructure. “This new microwave filter chip has the potential to improve wireless communication, such as 6G, leading to faster internet connections, better overall communication ...

In Switzerland, one in three employees suffers from workplace stress. Those affected often don’t realise that their physical and mental resources are dwindling until it’s too late. This makes it all the more important to identify work-​related stress as early as possible where it arises: in the workplace. Researchers at ETH Zurich are now taking a crucial step in this direction. Using new data and machine learning, they have developed a model that can tell how stressed we are just from the way we type and use our mouse. And there’s more: “How we type on our keyboard and move our mouse seems to be a better predictor of how stressed ...

Among Indigenous, rural non-industrial populations inhabiting the tropical forests of lowland Bolivia, researchers report, there appears to be an optimal balance between levels of food consumption and exercise that maximizes healthy brain aging and reduces the risk of disease. “We hypothesize that energy gain from food intake was positively associated with late life brain health in the physically active, food-limited world of our ancestors, but that obesity and other manifestations of a Western lifestyle ...

Despite the success of vaccines for preventing COVID-19, and of drugs for treating the disease, outcomes for severely ill patients admitted to the hospital remains poor. Identifying new therapies for severe COVID-19 remains a high priority and one in which Vanderbilt University Medical Center is taking a leading role.   A study published April 11 in the Journal of the American Medical Association (JAMA) evaluated two drugs that act on the renin-angiotensin system (RAS) as potential treatments for severe COVID-19. Severe acute respiratory syndrome coronavirus2 (SARS-CoV-2), the virus that causes COVID-19, enters ...

New research by the University of Warwick has identified characteristics of aggressive driving – which impact both road users and the transition to self-driving cars of the future.   In the first study to systematically identify aggressive driving behaviours, scientists have measured the changes in driving that occur in an aggressive state. Aggressive drivers drive faster and with more mistakes than non-aggressive drivers – putting other road users at risk and posing a challenge to researchers working on self-driving car technology.   The research comes as a leading Detective Chief Superintendent, Andy ...

Patients treated with blood pressure-lowering drugs can experience much greater improvements from a change of medication than from doubling the dose of their current medication. This is shown by a new study from Uppsala University, published in the Journal of the American Medical Association (JAMA). In this study, 280 patients tested four different blood pressure-lowering drugs over the course of a year. “The effect of a change of medication can be twice as great as the effect of doubling the dose of the patient’s current medication. It was clear in our study that certain patients achieved lower blood pressure from one drug than from another. This effect is ...

Cell secretions like proteins, antibodies, and neurotransmitters play an essential role in immune response, metabolism, and communication between cells. Understanding cell secretions is key for developing disease treatments, but current methods are only able to report the quantity of secretions, without any detail as to when and where they are produced. Now, researchers in the BIOnanophotonic Systems Laboratory (BIOS) in the School of Engineering and at the University of Geneva have developed a novel optical imaging ...

In Brazil, a group of researchers supported by FAPESP created mutant forms of Salmonella to understand the mechanisms that favor colonization of the intestinal tract of chickens by these pathogenic bacteria and find better ways to combat the infection they cause. An article on the study is published in the journal Scientific Reports. In it, the researchers note that, contrary to expectations, the mutant strains caused more severe infections than wild-type bacteria. In the mutant strains, the genes ttrA and pduA were deleted. In previous research using mice, both genes had been shown to account for the ability of Salmonella to ...

ANN ARBOR, Michigan — A cancer diagnosis can cause financial strain on patients as they cope with the cost of treatment and lost work. But what about their partners?   A new study from University of Michigan Rogel Cancer Center researchers surveyed the partners of colorectal cancer patients and found the financial impact of a loved one’s diagnosis also impacts the partner’s health-related quality of life.   “We know that financial toxicity or hardship is a significant effect of cancer and its treatment ...

ST. LOUIS, MO, April 10, 2023 – New research lead by Keith Slotkin, PhD, member, Donald Danforth Plant Science Center opens the door for scientists to equip plants with the tools they need to adapt to rising levels of carbon dioxide (CO2), high heat, and other stressors associated with climate change. The newly published study in the journal The New Phytologist revealed that the transgenerational inheritance occurred via DNA methylation, the process by which plants “mark” DNA without changing the code of the DNA itself ...

Coinciding with the increased support for populist parties that we have witnessed all over the West, the last decade has also seen an increase in the number of populism-related studies, covering topics such as the causes and consequences of voting for parties that support these ideas, or the reasons for and possible consequences of the emergence and increasing presence of the attitudes on which they are based. The links between conspiracy theories and populism have also aroused a great degree of interest. Carolina Galais, a researcher at the Universitat ...

OAK BROOK, Ill. – Researchers have found that digital breast tomosynthesis (DBT) has improved breast cancer screening performance in community practice and identifies more invasive cancers, compared to digital mammography. In addition, radiologists’ interpretive performance improved with DBT. The results of the study were published today in Radiology, a journal of the Radiological Society of North America (RSNA). “Our study demonstrated that more radiologists in U.S. community practice are meeting recommended performance standards with digital breast tomosynthesis than ...

A key receptor regulating memory formation has been localized to interneurons, according to a study with implications for drug development. Robert Pearce and colleagues probed the localization of γ-aminobutyric acid type A receptors that incorporate α5 subunits (α5-GABAARs). α5-GABAARs are concentrated within the hippocampus, a brain structure that is essential for the formation of episodic memories. The general anesthetic etomidate blocks learning by targeting α5-GABAARs, as do many drugs designed to enhance cognition, intended for use in people with Alzheimer’s disease, ...

In the process of organoid manufacturing, bioprinting technology can not only facilitate the creation and maintenance of complex biological 3D shapes and structures, but also allow for standardization and quality control during production. And the addition of artificial intelligence, which can validate the product potential in the manufacturing process, allows to provide a more standardized source of cells for the organoid in terms of viability, function, etc. In other words, bioprinting combined with artificial intelligence is expected to perform real-time ...

Colorectal cancer (CRC) is the most diagnosed cancer among males and third among females in Saudi Arabia, with up to two-thirds diagnosed at an advanced stage, according to the King Faisal Specialist Hospital & Research Centre. This report shows Saudi Arabia has a high percentage of respondents (62.7%) who never took CRC tests, far higher than global average of 54.1%. This shows the Kingdom's Early Cancer Detection Program still needs to build greater awareness among the public. To uncover attitudes and the ...

Drinking alcohol has also been linked to a raft of health problems in the human body, including heart disease, cirrhosis, and immune deficiency. One way to avoid those consequences ...

In the United States, federal laws were created to effectively decriminalize prostitution in minors under the age of 18. However, state and local justice systems continue to arrest and incarcerate minors for prostitution, despite widespread agreement that youth involved in commercial sexual exploitation are victims, not offenders.  Most youth tend to fall victim to child prostitution and sex trafficking between the ages of 12 and 14. Victims of child prostitution have especially high rates of prior physical, sexual and emotional abuse as well as neglect.  Calli M. Cain, Ph.D., an assistant professor at Florida Atlantic University’s College of Social Work and Criminal ...

Scientists at The Hospital for Sick Children (SickKids) and the University of Toronto (U of T) have combined forces to develop a new approach to potentially treat tumour cells, called mechanical nanosurgery, even for aggressive, chemoresistant cancers. Glioblastoma (GBM) is the most common and aggressive primary brain cancer. Despite various treatment options that exist, including surgery, radiotherapy, and chemotherapy, the median survival time for patients is only around 15 months. The current global standard-of-care treatment for GBM patients includes chemotherapy using a drug called temozolomide (TMZ), which extends a person’s life expectancy by approximately two months compared ...

Ithaca, NY—Deteriorating habitat conditions caused by climate change are wreaking havoc with the timing of bird migration. A new study demonstrates that birds can partially compensate for these changes by delaying the start of spring migration and completing the journey faster. But the strategy comes with a cost—a decline in overall survival. The findings by researchers from Cornell University, the University of Maryland, and Georgetown University are published in the journal Ecology.   "We found that our study species, the American Redstart, can migrate up to 43% faster to reach its ...
