Alzheimer’s disease (AD) is an age-related neurodegenerative disorder. β-amyloid (Aβ) deposition in the brain is a crucial contributor to the pathogenesis of AD, mitigating excessive cerebral Aβ burden has been considered as a possible therapeutic strategy for AD. Meningeal lymphatic vessels (MLVs) are recently discovered structures responsible for exchanging soluble components between the cerebrospinal fluid and interstitial fluid, and have been proved to be a potential pathway of Aβ drainage. Researchers at Huazhong University ...

Love is blind, the saying goes, and thanks to a world-first Australian study, we are now a step closer to understanding why. It is well known that romantic love changes the brain, releasing the so-called love hormone oxytocin, responsible for the euphoria we feel when falling in love. Now, researchers from the ANU, University of Canberra and University of South Australia have measured how a part of the brain is responsible for putting our loved one on a pedestal in that first flush of romance. In the world’s first study investigating the link between the human brain’s behavioural activation ...

Ammonia is a necessary feedstock to produce nitrogen-based fertilizers, chemicals, pharmaceuticals, and polymers. To date, about 80% of global ammonia is used to produce nitrogen-based fertilizers which relates to 50% of global food production. The global production of ammonia is about 180 million metric tons per year through the carbon-intensive and highly energy-consuming Haber-Bosch process. The high energy consumption, high carbon intensity, and high capital investment of the Haber-Bosch process make the development of environmentally sustainable and affordable routes for ammonia synthesis under ambient conditions more urgent. The electrochemical ammonia ...

Measuring airborne grass allergen levels instead of pollen counts will be more beneficial for hay fever sufferers as new research shows grass allergen levels are more consistently associated with hay fever symptoms than grass pollen counts.   The research, published today in The Journal of Allergy and Clinical Immunology and led by King’s College London and Imperial College London, shows for the first time that measuring airborne allergen levels will help people with hay fever better control their symptoms. 1 in 4 adults in the UK suffer from hay fever from late-March to September. Symptoms include a runny or blocked ...

Women with autoimmune disease are more likely to suffer from depression during pregnancy and after childbirth; conversely, women with a history of perinatal depression are at higher risk of developing autoimmune disease, a new study from Karolinska Institutet published in the journal Molecular Psychiatry reports. In autoimmune disease, the immune system mistakenly attacks the body’s own healthy tissue. Some of the most common autoimmune diseases are gluten intolerance (coeliac disease), autoimmune thyroiditis, rheumatoid ...

A study of seriously ill patients from academic medical centers across the country has found that nearly a quarter had a delayed or missed diagnosis.  All the patients had either been transferred to the intensive care unit (ICU) after being admitted or died in the hospital. The researchers concluded that three-quarters of these diagnostic errors contributed to temporary or permanent harm, and that diagnostic errors played a role in about one in 15 of the deaths.  The most common errors identified in the study involved delayed rather than missed diagnoses, for example because a specialist was consulted too late or an alternate diagnosis was not considered ...

LA JOLLA, CA— Ethanol—the compound found in alcoholic beverages—interferes with the normal functioning of a long list of biological molecules, but how each of these interactions contributes to the behavioral effects of alcohol is not fully understood. A guiding, but elusive, goal of researchers is to identify the protein (or proteins) to which ethanol binds that makes some people vulnerable to excessive drinking. Solving this question would point the way to effective therapies for alcohol use disorder, ...

As climate change fuels sea level rise, younger people will migrate inland, leaving aging coastal populations — and a host of consequences — in their wake, a study by Florida State University researchers finds. While destination cities will work to sustainably accommodate swelling populations, aging coastal communities will confront stark new challenges, including an outflow of vital human infrastructure such as health care workers, said Associate Professor of Sociology Matt Hauer, lead author of the study published in the Proceedings of the National Academy of ...

How do you deploy an environmental sensor to collect climate change readings over a prolonged period on an uninhabited island without failing? How do you power a seismic detector to operate for months in an underwater cave?   In environments that are difficult to reach because of the hazards or hardships for humans, a device behaving like a native plant could be the answer. This is the approach taken by Suyi Li, associate professor in mechanical engineering at Virginia Tech, and Clemson professor and collaborator Ian Walker. Their work is being advanced ...

Almost a quarter of patients who were admitted to the ICU or died in 29 hospitals in the United States experienced a diagnostic error Efforts and initiatives are underway across the country to address and prevent the causes of diagnostic errors A new study from researchers from Brigham and Women’s Hospital, a founding member of the Mass General Brigham healthcare system, in collaboration with researchers at the University of California San Francisco, has shed light on the rate and impact of diagnostic errors in hospital settings. In an analysis of electronic health records from 29 hospitals across the country of 2,428 patients who ...

In 1998, astrophysicists discovered that the universe is expanding at an accelerating rate, attributed to a mysterious entity called dark energy that makes up about 70% of our universe. While foreshadowed by earlier measurements, the discovery was somewhat of a surprise; at the time, astrophysicists agreed that the universe’s expansion should be slowing down because of gravity. This revolutionary discovery, which astrophysicists achieved with observations of specific kinds of exploding stars, called type Ia (read “type one-A”) ...

In recent years, research has begun to reveal that the lines of communication between the body’s organs are key regulators of aging. When these lines are open, the body’s organs and systems work well together. But with age, communication lines deteriorate, and organs don’t get the molecular and electrical messages they need to function properly. A new study from Washington University School of Medicine in St. Louis identifies, in mice, a critical communication pathway connecting the brain and the body’s fat tissue in a feedback loop ...

Every year, about 800,000 new stroke cases are reported in the United States, often causing patients problems with both neurological and physical motor control. Disruptions in the mobility of the arms and hands, in particular, can have devastating impacts on stroke patients’ quality of life. The restoration of arm extremity and hand dexterity are often the highest priority among stroke patients. A new robotic platform developed at the University of Rhode Island, which utilizes both a patient’s brainwaves and muscle activity, aims to help post-stroke patients perform needed rehabilitation and regain critical motor skills, including complex tasks like reaching and grasping ...

The initiative, funded through NSF’s Experiential Learning for Emerging and Novel Technologies (ExLENT) program, underscores Illinois Tech’s commitment to critical future technologies and expanding education to groups that have historically ...

PITTSBURGH — Contraceptive use is low among reproductive-aged people with disabilities who are enrolled in Medicare, according to a new study from the University of Pittsburgh that highlights how lack of contraceptive coverage by Medicare may prevent disabled enrollees from accessing contraception. Published today in the January issue of Health Affairs, the study provides the first national overview of contraceptive use among enrollees in Medicare, the government health insurance for people over 65 and for people with qualifying disabilities. ...

Since the Centers for Medicare and Medicaid Services launched the Acute Hospital Care at Home (AHCaH) Waiver in 2020, thousands of patients from across 300 hospitals in 37 states have been treated in their homes. Yet little is understood about these patients’ outcomes on a national level, and the waiver will end in December 2024 unless there is an act from Congress. A new study by investigators from Mass General Brigham analyzed outcomes from AHCaH for a diverse group of patients across America. The study provides preliminary evidence suggesting that home hospital ...

Children and adolescents who received one of the main COVID-19 vaccines were significantly protected from the illness and showed no increased signs of cardiac complications compared to young people who were not vaccinated, according to a new real-world study led by researchers from the Perelman School of Medicine at the University of Pennsylvania and Children’s Hospital of Philadelphia (CHOP). When the Delta variant rose to prominence, the study showed that vaccinated young people were 98 percent less likely to be infected than their unvaccinated peers, and ...

Research is shedding light and potentially expanding options for patients living with Medulloblastoma, an aggressive childhood cancer. Medulloblastoma is a cancer impacting both very young and school aged children.  When children get this type of brain tumor, they experience the process of the tumor blocking flow of fluid around the brain.  This can cause severe headaches, vomiting, sleepiness, fussiness, and difficulty walking and coordinating movements.  Treatment is intense, involving high dose chemotherapy, surgery, and sometimes radiation or stem cell transplants.  During these months long treatments, children may lose ...

Despite an alarming increase in overdose deaths among young people nationwide, a new “secret shopper”-style study led by Oregon Health & Science University researchers finds that access to residential addiction treatment centers for adolescents in the United States is limited and costly. The study, published today in the January issue of the journal Health Affairs, found that about half of the sites reported a wait time, and among those the average wait was almost a month. For those who do manage to find a placement, the average daily cost is $878 — with close to half of the facilities that provided information requiring partial or full payment upfront. For the average ...

Access to residential addiction treatment centers caring for U.S. adolescents under 18 years old in the United States is limited and costly, according to a new study supported by the National Institutes of Health. Researchers found that only about half (54%) of the residential addiction treatment facilities that they contacted had a bed immediately available, and for those that had a waitlist, the average estimated time before a bed opened was 28 days. In addition, the average daily cost per day of treatment was $878, with close to half (48%) of the facilities that provided information requiring partial or full payment upfront. ...

“TAR cloning is used to genetically engineer synthetic viruses with novel properties that may be used for the development of new vaccines.” BUFFALO, NY- January 8, 2024 – A new review paper was published in Oncotarget's Volume 14 on December 22, 2023, entitled, “Transformation-associated recombination (TAR) cloning and its applications for gene function; genome architecture and evolution; biotechnology and biomedicine.” Transformation-associated recombination (TAR) cloning represents a unique tool to selectively and efficiently recover a given chromosomal segment up to several hundred ...

UNIVERSITY PARK, Pa. — Mobile phones pack a lot of information into pocket-sized devices, which is why users may want to slow down the next time they’re scrolling through social media or checking email on a mobile app. People process information more efficiently but tend to be less vigilant about misinformation on their mobile phones compared to personal computers (PCs), according to a team led by Penn State researchers. This is especially true for users who have developed a routine or habit of using their ...

AMHERST, Mass. – In a first-of-its-kind research breakthrough, a team of scientists at the University of Massachusetts Amherst has analyzed and described what they call the “mosquito effect,” which sheds light on how certain pathogens, such as cancerous tumor cells, can outwit the body’s immune system. Just as mosquitoes ingest their host’s blood, the immune system’s T cells incorporate cytoplasmic material from tumors into their own cytoplasm. While it has long been known that many kinds of cells can transfer cellular material from one to another, the transfer of the cytoplasm has never been observed in T cells. Subsequent single-cell RNA (scRNA) ...
