Amsterdam, NL, January 26, 2021 - With medicinal cannabis now legalized in many parts of the world, there is growing interest in its use to alleviate symptoms of many illnesses including Parkinson's disease (PD). According to results of a survey of PD patients in Germany in the Journal of Parkinson's Disease, over 8% of patients with PD reported using cannabis products and more than half of those users (54%) reported a beneficial clinical effect. Cannabis products containing THC (tetrahydrocannabinol, the main psychoactive compound of cannabis) can be prescribed in Germany when previous therapies are unsuccessful or not tolerated, and where cannabis can be expected with not a very unlikely ...

COLUMBUS, Ohio - Research led by The Ohio State University Wexner Medical Center and College of Medicine found that the widely prescribed pain-relief drug gabapentin can prevent harmful structural changes in the injured spinal cords of mice, and also block cardiovascular changes and immune suppression caused by spinal cord injury. "Gabapentin is often prescribed as a treatment for pain, but if it is given early after injury - before symptoms develop - it can also limit structural changes in nerve cells. We show that these benefits remain even one month after stopping gabapentin treatment in spinal injured mice. We believe that gabapentin could be repurposed as a prophylactic therapy that can prevent autonomic dysfunction in ...

Nanoparticle is first therapy to trigger this novel way to kill lymphoma cells Drug is being developed for clinical trials Drug selectively attacks cancer cells, leaves normal cells unharmed CHICAGO --- Scientists at Northwestern Medicine have developed a novel therapy to trick cancer cells into gobbling up what they think is their favorite food - cholesterol - which actually triggers their destruction. What appears to them as a cholesterol-loaded particle is actually a synthetic nanoparticle that binds to the cancer cells and starves them to death. ...

Damage to the brain gray matter plays an important role in the progression of multiple sclerosis. This study now shows that such damage can be caused by inflammatory reactions that lead to loss of synapses, which impairs neural activity. Multiple sclerosis (MS) is a chronic inflammatory disease that affects the central nervous system, in which nerve cells are attacked by the patient's own immune system. In many cases, the disease develops into a progressive form, which is characterized by a shift of pathology from the white matter to the gray matter, ...

Every year, more than 400,000 people die from malaria, the majority are children under the age of five years old, who die from a disease which affects more than 200 million people a year. The most serious form of the disease is cerebral malaria which may cause severe neurological consequences and, in the worst-case scenario, result in death. The precise mechanism behind cerebral malaria has remained a mystery - until now, says a research group from the Department of Immunology and Microbiology at the University of Copenhagen. 'In our study, we show that a certain type of the malaria parasite can cross the blood-brain barrier by utilising ...

Mangrove ecosystems are at particular risk of being polluted by plastic carried from rivers to the sea. Fifty-four per cent of mangrove habitat is within 20 km of a river that discharges more than a tonne of plastic waste a year into the ocean, according to a new paper published in the journal Science of the Total Environment. Mangroves in southeast Asia are especially threatened by river-borne plastic pollution, the researchers found. The paper, written by scientists at GRID-Arendal and the University of Bergen, is the first global assessment of coastal environments' exposure to river-borne plastic pollution. The majority of plastic waste carried to sea by rivers ends up trapped along coastlines, but some types ...

FORT LAUDERDALE/DAVIE, Fla. - Global warming or climate change. It doesn't matter what you call it. What matters is that right now it is having a direct and dramatic effect on marine environments across our planet. "More immediately pressing than future climate change is the increasing frequency and severity of extreme 'underwater heatwaves' that we are already seeing around the world today," Lauren Nadler, Ph.D., who is an assistant professor in Nova Southeastern University's (NSU) Halmos College of Arts and Sciences . "This phenomenon is what we wanted to both simulate and understand." Nadler is a co-author of a new study on this topic, which you can find published online ...

Scientists have designed a single-dose universal vaccine that could protect against the many forms of leptospirosis bacteria, according to a study published today in eLife. An effective vaccine would help prevent the life-threatening conditions caused by leptospirosis, such as Weil's disease and lung haemorrhage, which are fatal in 10% and 50% of cases, respectively. Leptospirosis is caused by a diverse group of spirochetes called leptospires. A broad range of mammals, including rats, harbour the bacteria in their kidneys and release them into the environment through their urine. Humans and animals can then get infected after coming into contact with contaminated water or soil. In addition to having a major impact on the health of vulnerable human populations, ...

Syracuse, N.Y. - As President Joe Biden seeks to raise the federal minimum wage, a new study published recently by researchers from Syracuse University shows that a higher minimum wage will reduce infant deaths. In the study, "Effects of US state preemption laws on infant mortality," Syracuse University professors found that each additional dollar of minimum wage reduces infant deaths by up to 1.8 percent annually in large U.S. cities. The study was published recently by Preventive Medicine. The federal minimum wage has not been increased since 2009, and Biden's $1.9 trillion American Rescue Plan to aid those hit hardest by the COVID-19 pandemic calls for Congress to raise the minimum wage from $7.25 ...

CAMBRIDGE, MD (January 26, 2021)--The Chesapeake Bay has a long history of nutrient pollution resulting in degraded water quality. However, scientists from the University of Maryland Center for Environmental Science are reporting some improvements in the Choptank River on Maryland's Eastern Shore. The Choptank is a tributary of Chesapeake Bay, and its watershed lies primarily in the state of Maryland, with a portion in Delaware. There are strong similarities between the Choptank basin and the Chesapeake as a whole, which enables the Choptank to be used as a model for progress in the Bay. The Chesapeake Bay is an estuary which has undergone considerable ...

Researchers from McGill University have discovered, for the first time, one of the possible mechanisms that contributes to the ability of lysergic acid diethylamide (LSD) to increase social interaction. The findings, which could help unlock potential therapeutic applications in treating certain psychiatric diseases, including anxiety and alcohol use disorders, are published in the journal PNAS. Psychedelic drugs, including LSD, were popular in the 1970s and have been gaining popularity over the past decade, with reports of young professionals claiming to regularly take small non-hallucinogenic micro-doses of ...

Black holes are considered amongst the most mysterious objects in the universe. Part of their intrigue arises from the fact that they are actually amongst the simplest solutions to Einstein's field equations of general relativity. In fact, black holes can be fully characterized by only three physical quantities: their mass, spin and charge. Since they have no additional "hairy" attributes to distinguish them, black holes are said to have "no hair": Black holes of the same mass, spin, and charge are exactly identical to each other. Dr. Lior Burko of Theiss Research in collaboration with Professor Gaurav Khanna of the University of Massachusetts Dartmouth and the University ...

Landslides caused by the collapse of unstable volcanoes are one of the major dangers of volcanic eruptions. A method to detect long-term movements of these mountains using satellite images could help identify previously overlooked instability at some volcanoes, according to Penn State scientists. "Whenever there is a large volcanic eruption, there is a chance that if a flank of the volcano is unstable there could be a collapse," said Judit Gonzalez-Santana, a doctoral student in the Department of Geosciences. "To better explore this hazard, we applied an increasingly popular and more sensitive time-series method to look at these movements, or surface ...

CHAMPAIGN, Ill. -- The Medicaid expansion facilitated by the Affordable Care Act led to increases in the identification of undiagnosed HIV infections and in the use of HIV prevention services such as preexposure prophylaxis drugs, says new research co-written by a team of University of Illinois Urbana-Champaign experts who study the intersection of health care and public policy. The research by Dolores Albarracín, a professor of psychology and of business administration at Illinois, and Bita Fayaz Farkhad, an economist and a postdoctoral researcher in psychology at Illinois, ...

Corn hasn't always been the sweet, juicy delight that we know today. And, without adapting to a rapidly changing climate, it is at risk of losing its place as a food staple. Putting together a plant is a genetic puzzle, with hundreds of genes working together as it grows. Cold Spring Harbor Laboratory (CSHL) Professor David Jackson worked with Associate Professor Jesse Gillis to study genes involved in corn development. Their teams analyzed thousands of individual cells that make up the developing corn ear. They created the first anatomical map that shows where and when important ...

Pneumonia and the flu kill tens of thousands of Americans each year, racking up billions of dollars in medical costs and even more in lost productivity. But new research from the University of Georgia shows that state laws promoting flu vaccinations for hospital workers can substantially reduce the number of influenza-related deaths. Spanning 23 years, the study looked at the mortality rate from influenza and pneumonia during peak flu season (from December through March of each year), comparing changes in mortality over time in the 13 states and Washington, D.C., that adopted laws to the changes in mortality in states without laws. ...

The health of aquatic ecosystems depends on the supply of key nutrients, especially phosphorus. Too much phosphorus results in unwanted eutrophication, and much effort is spent on preventing phosphorus pollution of water bodies. In the World's largest freshwater ecosystem, the North American Great Lakes, this control may have recently been lost to an invasive species. According to a new study, quagga mussels, which have spread across four of the five Great Lakes, have accumulated large amounts of phosphorus in their biomass, to the degree that their activities now regulate the supply of phosphorus ...

Their field may not be top of mind among those that contribute to the greater good, yet new research from the University of Notre Dame shows marketers can help entrepreneurs in emerging markets grow their businesses, which in turn helps them to improve lives, sustain livelihoods, enhance overall living standards and strengthen societies. "Do Marketers Matter for Entrepreneurs? Evidence from a Field Experiment in Uganda" is forthcoming in the Journal of Marketing from Frank Germann, an associate professor of marketing at Notre Dame's Mendoza College of Business who teaches ...

Cell phone data that is routinely collected by telecommunications providers can reveal changes of behavior in people who are diagnosed with a flu-like illness, while also protecting their anonymity, a new study finds. The Proceedings of the National Academy of Sciences (PNAS) published the research, led by computer scientists at Emory University and based on data drawn from a 2009 outbreak of H1N1 flu in Iceland. "To our knowledge, our project is the first major, rigorous study to individually link passively-collected cell phone metadata with actual public health data," says Ymir Vigfusson, assistant professor in Emory University's Department of Computer Science and a first author of the study. "We've shown ...

WASHINGTON -- A multi-institutional group of researchers has developed new metamaterial tiles that will help improve the sensitivity of telescopes being built at the preeminent Simons Observatory in Chile. The tiles have been incorporated into receivers that will be deployed at the observatory by 2022. The Simons Observatory is the center of an ambitious effort to measure the cosmic microwave background -- electromagnetic radiation left over from an early stage of the universe -- using some of the world's largest and most sophisticated ground-based telescopes. ...

Providing economic relief to struggling families can lead to another positive effect -- fewer cases of child neglect, according to new research by the University of Washington. A 10% increase in a common benefit for low- to moderate-income working families, the Earned Income Tax Credit, led to a 9% decrease in the annual number of reports of child neglect made to child welfare agencies over a 14-year study period. That's a significant impact, researchers say, and can inform future social policies. The study is relevant to current policy actions, as President Joe Biden has recently proposed an expansion ...

RESEARCH TRIANGLE PARK, N.C. -- Kombucha tea, a trendy fermented beverage, inspired researchers to develop a new way to generate tough, functional materials using a mixture of bacteria and yeast similar to the kombucha mother used to ferment tea. With Army funding, using this mixture, also called a SCOBY, or symbiotic culture of bacteria and yeast, engineers at MIT and Imperial College London produced cellulose embedded with enzymes that can perform a variety of functions, such as sensing environmental pollutants and self-healing materials. The team also showed that they could incorporate yeast directly into the cellulose, creating living materials that could be used to purify water for Soldiers in the field or make smart packaging materials that can detect damage. "This ...

COLUMBIA, Mo. - In 2016, the World Health Organization called the Zika virus epidemic a "public health emergency of international concern" due to the virus causing birth defects for pregnant women in addition to neurological problems. Since then, researchers have wrestled with different strategies for controlling the spread of Zika virus, which gets transmitted to humans from female mosquito bites. One approach, which was approved by the Environmental Protection Agency in May, will release more than 750 million genetically modified mosquitos into the Florida Keys in 2021 and 2022. These "suicide mosquitos" are genetically-altered to produce offspring that die before emerging into adults and therefore cannot ...
