New Curtin research has shown how a readily available, cheap and safe-to-use product found in the medicine cabinet of most homes could be the key to better ecological restoration practices with major benefits for the environment and agriculture. The study revealed that aspirin, which naturally occurs in the bark of the willow tree and other plants, can improve the survival of grass species important for ecological restoration and sustainable pasture when applied in a seed coating. Lead researcher Dr Simone Pedrini from the ARC Centre for Mine Site Restoration in Curtin's School of Molecular and Life Sciences, said salicylic acid has been used for its medicinal properties for more than 4000 years and its modern synthetic version, acetylsalicylic acid, or aspirin, is one ...

Our genetic material is stored in our cells in a specific way to make the meter-long DNA molecule fit into the tiny cell nucleus of each body cell. An international team of researchers at the Max Planck Institute for Biology of Ageing, the CECAD Cluster of Excellence in Ageing research at the University of Cologne, the University College London and the University of Michigan have now been able to show that rapamycin, a well-known anti-ageing candidate, targets gut cells specifically to alter the way of DNA storage inside these cells, and thereby promotes gut health and longevity. This effect has been observed in flies and mice. The researchers believe this finding will open up new possibilities for targeted therapeutic interventions ...

BOSTON - A new analysis by researchers at Massachusetts General Hospital (MGH) offers a novel perspective on the disproportionate impact that COVID-19 has had on people of color, low-income populations, and other structurally disadvantaged groups. Their findings, published in a research letter to the END ...

For decades, physicians and dieticians have urged people to limit their intake of high fat foods, citing links to poor health outcomes and some of the leading causes of death in the U.S., such as diabetes, heart disease and cancer. According to the Centers for Disease Control and Prevention, dietary components high in saturated fats such as red meat are thought to be risk factors for colon cancer. Diet is thought to strongly influence the risk of colorectal cancer, and changes in food habits might reduce up to 70% of this cancer burden. Other known epidemiological risk factors are family history, inflammatory bowel disease, ...

Watching what was happening around the world in early 2020, University of California San Diego School of Medicine researchers knew their region would likely soon be hit with a wave of patients with COVID-19, the infection caused by the coronavirus SARS-CoV-2. They wondered how the virus persists on surfaces, particularly in hospitals, and they knew they had only a small window of time to get started if they wanted to capture a snapshot of the "before" situation -- before patients with the infection were admitted. After a call late one Sunday night, a team assembled in the ...

MELVILLE, N.Y., June 9, 2021 -- In the evolutionary battle between hunter and hunted, sound plays an integral part in the success or failure of the hunt. In the case of bats vs. moths, the insects are using acoustics against their winged foes. During the 180th Meeting of the Acoustical Society of America, which will be held virtually June 8-10, Thomas Neil, from the University of Bristol, will discuss how moth wings have evolved in composition and structure to help them create anti-bat defenses. The session, "Moth wings are acoustic metamaterials," will take place Wednesday, June 9, at 1 p.m. Eastern U.S. Nocturnal moths ...

MELVILLE, N.Y., June 9, 2021 -- The prolonged impact of the COVID-19 pandemic and the interaction restrictions created widespread lockdown fatigue and increased social tension in multiunit housing. But small improvements in quality-of-life routines may help people cope with the health restrictions better than they previously could. During the 180th Meeting of the Acoustical Society of America, which will be held virtually June 8-10, Braxton Boren, from American University, will discuss noise prevention techniques and the use of alterative acoustic stimulation to help those who find themselves in pandemic-related lockdowns. The session, "The Soundscape of Quarantine," will take place Wednesday, June 9, at 1:45 p.m. Eastern U.S. While there have been studies about ...

The SARS-CoV-2 papain-like protease (PLpro) plays an essential role in processing viral proteins needed for replication. In addition, the enzyme can cut and inactivate some human proteins important for an immune response. Now, researchers reporting in ACS Infectious Diseases have found other targets of PLpro in the human proteome, including proteins involved in cardiovascular function, blood clotting and inflammation, suggesting a link between the inactivation of these proteins and COVID-19 symptoms. Viruses like SARS-CoV-2 make multiple proteins as one long "polyprotein." Viral enzymes called proteases recognize specific amino acid sequences in this polyprotein and cut them to release individual proteins. ...

A cell-penetrating peptide developed by researchers at Vanderbilt University Medical Center can prevent, in an animal model, the often-fatal septic shock that can result from bacterial and viral infections. Their findings, published this week in Scientific Reports, could lead to a way to protect patients at highest risk for severe complications and death from out-of-control inflammatory responses to microbial infections, including COVID-19. "Life-threatening microbial inflammation hits harder (in) patients with metabolic syndrome, a condition afflicting millions of people in the United States and worldwide," said the paper's corresponding author, Jacek Hawiger, MD, PhD, the Louise B. McGavock Chair in Medicine and Distinguished Professor of Medicine ...

OAKLAND, Calif. -- The significant declines in heart attack hospitalizations and emergency care for possible strokes seen in Northern California at the beginning of the COVID-19 pandemic were not seen in subsequent surges, new research from Kaiser Permanente shows. The study, published June 2 in JAMA, suggests public health campaigns that encouraged people to seek care if they were experiencing signs or symptoms of a stroke or heart attack were effective. "In May 2020, we reported that, in the early months of the pandemic, the weekly number of patients admitted to our hospitals for a heart attack fell to nearly half of what would be expected," said the study's lead author Matthew ...

A new study identifies a novel biomarker indicating resilience to chronic stress. This biomarker is largely absent in people suffering from major depressive disorder, and this absence is further associated with pessimism in daily life, the study finds. Nature Communications published the research by scientists at Emory University. The researchers used brain imaging to identify differences in the neurotransmitter glutamate within the medial prefrontal cortex before and after study participants underwent stressful tasks. They then followed the participants for four weeks, using a survey protocol to regularly assess how participants rated their expected and experienced outcomes for daily activities. "To our knowledge, this is the first work to show ...

A new study published in the Journal of the American Geriatrics Society suggests that survival rates after heart transplant surgery are similar in adults ages 18 to 69 and adults ages 70 and older. Researchers examined a large U.S. database of patients who were listed as candidates for surgery to replace their failing hearts with healthier donor hearts. The researchers found that: Only 1 in 50 people who are considered for heart transplant surgery and 1 in 50 people who receive a heart transplant are ages 70 or older. For older adults in the study, the likelihood of surviving one or five years after a heart transplant was about the same as for younger adults. Having a ...

Early in her career neuroscientist Allyson Mackey began thinking about molars. As a researcher who studies brain development, she wanted to know whether when these teeth arrived might indicate early maturation in children. "I've long been concerned that if kids grow up too fast, their brains will mature too fast and will lose plasticity at an earlier age. Then they'll go into school and have trouble learning at the same rate as their peers," says Mackey, an assistant professor in the Department of Psychology at Penn. "Of course, not every kid who experiences stress or [is] low income will show this pattern of accelerated development." What would help, she thought, was a scalable, objective way—a physical manifestation, ...

Even the best face masks work only as well as their fit. And poorly fitting face masks greatly increase the risk of infection from airborne pathogens compared to custom-fitted masks, according to a new study by the University of Cincinnati. Researchers in UC's College of Engineering and Applied Science used computerized tomography or CT scans of three different-sized face masks attached to three different-sized dummy heads to measure the gaps between the face and the fabric. Then they calculated the leaks from these gaps to determine the infection risk.  They found that while N95 masks are effective barriers against airborne diseases like COVID-19, poorly ...

Scientists have developed polypeptide-based materials that act as effective vectors for delivering gene therapies. The first-of-its-kind platform enables the vectors to be adapted to suit the specific gene therapy cargo. The work, led by researchers from RCSI University of Medicine and Health Sciences and funded by Science Foundation Ireland, is published in Biomaterials Science. A major challenge for gene therapies is preparing them in a way that can deliver the genetic information into the host cells. For the Covid-19 vaccines that use mRNA technology, the genetic information is delivered ...

DARIEN, IL - A study of nearly 2,500 adults found that having trouble falling asleep, as compared to other patterns of insomnia, was the main insomnia symptom that predicted cognitive impairment 14 years later. Results show that having trouble falling asleep in 2002 was associated with cognitive impairment in 2016. Specifically, more frequent trouble falling asleep predicted poorer episodic memory, executive function, language, processing speed, and visuospatial performance. Further analysis found that associations between sleep initiation and later cognition were partially explained by both depressive symptoms and vascular ...

DARIEN, IL - A 15-year longitudinal study shows that childhood insomnia symptoms that persist into adulthood are strong determinants of mood and anxiety disorders in young adults. Results show that insomnia symptoms persisting from childhood through adolescence and into adulthood were associated with a 2.8-fold increased risk of internalizing disorders. Insomnia symptoms that newly developed over the course of the study were associated with a 1.9-fold increased risk of internalizing disorders. No increased risk of internalizing disorders was found for those children in whom insomnia symptoms remitted during the study period. "We found that about ...

MELVILLE, N.Y., June 9, 2021 -- The world is filled with myriad sounds that can overwhelm a person with relentless acoustics. Noise is so prevalent in everyday life that the concept and achievement of comfortable quiet is hard to define. During the 180th Meeting of the Acoustical Society of America, which will be held virtually June 8-10, Aggelos Tsaligopoulos, from the University of the Aegean, will describe how quiet could be measured in the hopes of better understanding its impact on people. The session, "Towards a new understanding of the concept of quietness," will take place Wednesday, ...

In a major scientific leap, University of Queensland researchers have created a quantum microscope that can reveal biological structures that would otherwise be impossible to see. This paves the way for applications in biotechnology, and could extend far beyond this into areas ranging from navigation to medical imaging. The microscope is powered by the science of quantum entanglement, an effect Einstein described as "spooky interactions at a distance". Professor Warwick Bowen, from UQ's Quantum Optics Lab and the ARC Centre of Excellence for Engineered Quantum Systems (EQUS), said it was the first entanglement-based sensor with performance beyond the best possible existing technology. "This breakthrough will spark all sorts of new technologies - from better navigation ...

While the IPCC is in the midst of the drafting cycle of the Sixth Assessment Report, whose publication will start in the second half of 2021 - one of the most relevant events for the global climate change community, there is an ongoing debate on how to assess the feasibility of ambitious climate mitigation scenarios developed through integrated assessment models and to what extent they are actually achievable in the real world. In their new study published in Environmental Research Letters, researchers from the RFF-CMCC European Institute on Economics and the Environment (EIEE) and IIASA developed a systematic ...

A condition that affects the blood, known as idiopathic thrombocytopenic purpura (ITP), may be associated the Oxford-AstraZeneca vaccine in rare cases, research suggests. The very small increased risk of the condition - which is characterised by low platelet counts - is estimated to be 11 per million doses, similar to figures seen in vaccines for flu and MMR. A low number of platelets - blood cells that help prevent blood loss when vessels are damaged - can result in no symptoms or can lead to an increased risk of bleeding or, in some cases, clotting. Researchers say that the increased chance of developing ITP after receiving the vaccine remains smaller than the risk of developing it because of Covid-19 and should ...

Batteries have come a long way since Volta first stacked copper and zinc discs together 200 years ago. While the technology has continued to evolve from lead-acid to lithium-ion, many challenges still exist--like achieving higher density and suppressing dendrite growth. Experts are racing to address the growing, global need for energy-efficient and safe batteries. The electrification of heavy-duty vehicles and aircraft requires batteries with more energy density. A team of researchers believes a paradigm shift is necessary to make a significant impact in battery technology for these industries. ...
