People suffering from post-COVID have been discouraged from exercising because early observations  suggested it could be harmful. In a study published in JAMA Network Open, researchers from Karolinska Institutet show that post-covid does not mean that exercise must be strictly avoided.  People affected by post-COVID often experience symptoms such as extreme fatigue, shortness of breath, high resting heart rate, and muscle weakness. Symptoms are often exacerbated by exertion.  “The World Health Organization (WHO) and other major bodies have said that people with post-covid ...

Viruses need hosts. Whether it’s measles, the flu or coronavirus, viral pathogens cannot multiply or infect other organisms without the assistance of their hosts’ cellular infrastructure. However, humans are not the only ones affected by viruses: animals, plants and even microorganisms can all serve as hosts. Viruses that use bacteria as host cells are called bacteriophages (or simply “phages” for short) and are thought to be the most abundant biological entities of all. Just as the human immune system springs ...

OAK BROOK, Ill. – A new study found increased coronary vessel wall thickness that was significantly associated with impaired diastolic function in asymptomatic, middle-aged individuals living with HIV. The study was published today in Radiology: Cardiothoracic Imaging, a journal of the Radiological Society of North America (RSNA). According to the World Health Organization, approximately 39 million people were living with HIV at the end of 2022. Since 2010, HIV-related deaths have been reduced by 51%, but HIV continues to be a major global public health issue, claiming 40.4 million lives so far.  As effective therapy drugs increase ...

(WASHINGTON, April 4, 2024) – A study published today in Blood Advances showed that among patients in Denmark who had slow-growing chronic lymphocytic leukemia (CLL) with no symptoms and a low risk for ever needing treatment, those who stopped seeing their doctors for specialized follow-up had fewer hospital visits, fewer infections, and similar survival after three years compared to those who continued to undergo specialized follow-up. “To the best of our knowledge, ours is the first study ...

Sandsæter is a midwife and has seen the development first hand. Increasing numbers of pregnant women are overweight. Heidi Sandsæter has studied what overweight and obese pregnant women perceive as the cause of this development. “Research in other countries has shown that there is a direct correlation between weight and a difficult childhood in some adults. We wanted to find out if this was also the case in wealthy Norway,” says Sandsæter. She is a PhD candidate at the Department of Public Health and Nursing at the Norwegian University of Science and Technology (NTNU), and has used data ...

A new study published in Social Psychological and Personality Science investigated the factors influencing orgasm rates for women across sexual orientations. The researchers report that partner gender plays a significant role in how women approach sex. and their likelihood of reaching orgasm. Understanding the Orgasm Gap Previous research has established the existence of an "orgasm gap," where cisgender women are less likely to achieve orgasm during partnered sex compared to cisgender men. This new study delves deeper, ...

Highlights: Colorectal cancer is associated with a disrupted gut microbiome. About 40% of people with colorectal cancer have a mutation in the KRAS gene. Researchers in China connect the 2 in a new study. Their findings identify distinct microbial signatures in patients with and without KRAS mutations. The work points to a potential noninvasive biomarker for determining a person’s KRAS status after a colorectal cancer diagnosis. Washington, D.C.—For about 40% of people diagnosed with colorectal cancer (CRC), the tumor carries a mutation in a gene called KRAS. Many of those mutations have been linked to shorter survival and ...

Researchers have made a breakthrough into how two chronic respiratory diseases in childhood affect the immune system, paving the way for better treatments. The research, led by Murdoch Children’s Research Institute (MCRI) and published in Mucosal Immunology, has found suppurative lung disease and wheezing have the same inflammatory profiles despite their differing symptoms. MCRI Dr Melanie Neeland said while suppurative lung disease and wheezing were  common in children, due to a poor understanding of the underlying mechanisms, treatment options were limited and disease recurrence ...

Each year more than 500,000 Americans undergo percutaneous coronary intervention, or PCI, a minimally invasive procedure to unclog the arteries that feed the heart.  While PCI, which includes both angioplasty and stenting, is one of the most common operations in the world, it does carry a small (about 1-2%) but significant risk of death. Around 10% of all deaths following percutaneous coronary intervention are potentially preventable, a study led by Michigan Medicine finds.  The results are published in PLOS ONE.  “Deaths in the hospital after PCI are rare and mostly occur in patients ...

Cold Spring Harbor Laboratory (CSHL) chemists have created a new collection of molecular compounds and begun testing them as potential leads in the search for new drugs. Among these molecules, they found several that show promise for development as antibiotics and cancer therapies. Sounds like a eureka moment? Well, sort of. But it’s more a case of hard chemistry made simple. The new compounds were synthesized using an efficient new way of linking molecules together, developed in the lab of CSHL Professor John Moses. Moses calls his innovative process Accelerated SuFEx Click Chemistry (ASCC). ...

An extensive CO2 monitoring network set up around the San Francisco Bay Area by an atmospheric chemist from the University of California, Berkeley, has recorded the first evidence that the adoption of electric vehicles is measurably lowering the area's carbon emissions. The network of sensors, most of them in the East Bay, is the brainchild of Ronald Cohen, UC Berkeley professor of chemistry, who envisions inexpensive, publicly funded pollution and carbon dioxide monitors widely distributed around urban areas to pinpoint emission sources and the ...

Toronto, CANADA & Rotterdam NETHERLANDS – March 2024 – The SynGAP Research Fund 501(c)(3) today announced a grant to Dr. Danielle Andrade, Dr. Miles Thompson, Dr. Ryan Yuen, Dr. Rogier Kerssebook, and Dr. Anatoljevna Anna Kattentidt to support research on SynGAP-Related Disorder (SRD) in adults. SRD is a rare neurodevelopmental disorder that causes severe intractable epilepsy, and intellectual disability, and is one of the leading genetic causes of autism (1,2).  Dr. Andrade’s team recently published the only research on SRD in adults ...

A scientific review has found almost no research studying the interconnections across three major threats to planetary health, despite UN assessments suggesting one million species are at risk of extinction, a global pandemic that resulted in over six million excess deaths, and a record-breaking year of global temperatures. “When we began to look into it, we had suspicions the number of studies would be low, but not that low,” says Dr. Jonathan Davies, a researcher with University of ...

The approval of marijuana for medical use has had little effect on the mental health of the general population in the US. But legalization for therapeutic purposes does benefit those for whom it is intended. This is the conclusion of a study by researchers at the University of Basel. In the US, access to marijuana has been facilitated in most states since the mid-1990s – whether through medical clearance or through decriminalization of recreational use. However, liberalization is still controversial, and the effects on the well-being of specific groups and the therapeutic value ...

The ecosystems we live in don’t work the way they used to — and that’s bad for our health. Climate change, pollution, and falling biodiversity are all damaging our immune systems. The lack of positive environmental exposures to build the strength of our immune systems, and the increasing negative exposures which attack those systems, are combining to cause a dramatic rise in immune-mediated diseases like asthma and cancer. Measures to protect against this could have a very powerful return on investment: an estimated $1 spent on climate change mitigation saves $3 on healthcare costs. A global ...

A study led by Medical Research Council (MRC) researchers has identified genetic variants in two genes that have some of the largest impacts on obesity risk discovered to date. The discovery of rare variants in the genes BSN and APBA1 are some of the first obesity-related genes identified for which the increased risk of obesity is not observed until adulthood. The study, published in Nature Genetics, was led by researchers at the MRC Epidemiology Unit and the MRC Metabolic Diseases Unit at the Institute of Metabolic Science, both based at the University ...

Age matters when determining how to protect life in the ocean; every population needs a strong cohort of adults to produce the next generation. But many marine protected areas (MPAs) are falling short of their most basic purpose: to rebuild struggling fish populations. In a new study published April 4 in Global Change Biology, scientists looked at the age breakdown of reef fish in marine protected areas for the first time. They discovered in almost all of them, adult fish populations have either flatlined or declined. “Adult fish are really important,” said ...

ROCHESTER, Minn. — A recent Mayo Clinic study suggests that active workstations incorporating a walking pad, bike, stepper and/or standing desk are successful strategies for reducing sedentary time and improving mental cognition at work without reducing job performance. Extended sedentary behavior, whether at work or home, increases a person's risk of preventable chronic diseases. "Our findings suggest that it is feasible to blend movement with office work that previously would have been done during long periods of sitting. Active workstations may ...

A research group coordinated by the University of Helsinki was able to measure a spike in radiocarbon concentration of trees in Lapland that occurred after the Carrington flare. This discovery helps to prepare for dangerous solar storms. The Carrington Event of 1859 is one of the largest recorded solar storms in the last two centuries. It was seen as white light flares on a giant sunspot group, fires at telegraph stations and disturbances in geomagnetic measurements, as well as aurorae even in tropical regions. In a joint study carried ...

Even in nature, pride can prevail. A study with researchers from the University of Gothenburg shows that sea anemones that react more slowly to change can survive a heatwave better than individuals that change their behaviour quickly. Along the Atlantic coasts of Europe, many species are exposed to abrupt shifts in habitat. Tides, storms and rapid temperature changes are commonplace for the marine species that live there. With climate change, heatwaves are expected to become more frequent, and researchers wanted to find out how coastal marine species cope with extreme water temperatures. They chose to study the sea anemone species Actinia ...

AMHERST, Mass. – Recent research led by the University of Massachusetts Amherst evaluates how well machine learning can identify different insect species by their sound, from malaria-carrying mosquitoes and grain-hungry weevils to crop-pollinating bees and sap-sucking cicadas. Listening in on the insect world gives us a way to monitor how populations of insects are shifting, and so can tell us about the overall health of the environment. The study, published in the Journal of Applied Ecology, suggests that machine and deep learning are becoming the gold standards for automated ...

Changing weather patterns induced by climate change are contributing to shifts in the location of terrorist activity, according to new research. An exploratory study led by extremism expert Dr Jared Dmello, from the University of Adelaide’s School of Social Sciences, found some climatological variables affected terrorist activity in India. “Suitability analyses indicate that all the climatological variables tested – temperature, precipitation, and elevation – relate to shifting patterns of terrorist activity,” says Dr Dmello. “Urban centres have increasingly grown in population ...

Forming a long-term recreational exercise habit as a young person has a beneficial impact on physical and mental health later in life, but some groups, such as females and academic high-achievers, miss out on these benefits disproportionately. A University of Adelaide study found females, people with low self-efficacy, reluctant exercisers, higher academic achievers, and those experiencing socioeconomic disadvantage are all most at risk of failing to establish regular exercise patterns during the transition from adolescence to young adulthood. The finding was made by examining data collected as part of the Longitudinal Survey of Australian ...

(Santa Barbara, Calif.) — A spectrum of neurodegenerative diseases, including frontotemporal dementia (FTD), progressive supranuclear palsy (PSP) and corticobasal degeneration (CBD) are due to the accumulation of abnormal, misfolded tau proteins in the brain. A team of researchers led by UC Santa Barbara scientists has found potential ways to interrupt this process by targeting “sticky” sites along the long form of mutated tau, preventing the misfolding and spreading of the neurofibrillary tangles. “This is ...
