Scientists from the UCLA Jonsson Comprehensive Cancer Center have developed a simple, high-throughput method for transferring isolated mitochondria and their associated mitochondrial DNA into mammalian cells. This approach enables researchers to tailor a key genetic component of cells, to study and potentially treat debilitating diseases such as cancer, diabetes and metabolic disorders. A study, published

Black children are removed from their families at much greater rates than any other race or ethnicity in this country. At the same time the sheer number of all child abuse investigations in the US is staggering: experts estimate that by age 18 one out of three children has been the subject of a child
The Grain Chain, a farm to fork coalition of stakeholders in the grain industry sector and chaired by the American Bakers Association (ABA), celebrates the recommendation published today in the 2020-2025 Dietary Guidelines for Americans (DGAs) to “consume half of your grains from whole grain sources” and the remainder from enriched grains. A foundational piece
President Donald Trump on Wednesday deflected criticism for a slower-than-expected rollout of the Covid-19 vaccine, saying the U.S. has distributed the lifesaving shots but states have to administer them. More than 11.4 million doses of Pfizer and Moderna’s two-dose vaccines have been distributed across the country as of Monday morning, but just over 2.1 million
About one in 100 children has a common brain disorder called Chiari 1 malformation, but most of the time such children grow up normally and no one suspects a problem. But in about one in 10 of those children, the condition causes headaches, neck pain, hearing, vision and balance disturbances, or other neurological symptoms. In
Posttraumatic stress disorder (PTSD) is a complex psychiatric disorder brought on by physical and/or psychological trauma. How its symptoms, including anxiety, depression and cognitive disturbances arise remains incompletely understood and unpredictable. Treatments and outcomes could potentially be improved if doctors could better predict who would develop PTSD. Now, researchers using magnetic resonance imaging (MRI) have

Researchers at the Kobe University Graduate School of Medicine have revealed that alterations in fetal microglia resulting from maternal inflammation could contribute towards the onset of developmental and psychiatric disorders. The research team including PhD student OZAKI Kana and Professor YAMADA Hideto et al. from the Department of Obstetrics and Gynecology observed that infant mice
Analysis of ancient DNA reveals the genetic makeup of the people who lived in the Caribbean between about 400 and 3,100 years ago, settling several archaeologic and anthropologic debates and reaching startling conclusions about Indigenous population sizes before contact with Europeans.

A research team led by Dr Xiaoyu Li from the Research Division for Chemistry, Faculty of Science, in collaboration with Professor Yizhou Li from School of Pharmaceutical Sciences, Chongqing University and Professor Yan CAO from School of Pharmacy, Second Military Medical University in Shanghai has developed a new drug discovery method targeting membrane proteins on
President-elect Joe Biden plans to invoke the Defense Production Act after he takes office next month to boost production of Covid vaccines, a member of his Covid-19 advisory team said Monday. “You will see him invoking the Defense Production Act,” Dr. Celine Gounder, a member of Biden’s Covid-19 advisory board, said during an interview on
Results of a national study show significant sex and age-based differences among youth and young adults who experience a nonfatal opioid overdose. Female youth between the ages of 11 and 16 have a higher incidence of nonfatal opioid overdose compared to male youth of the same age. That reverses at age 17, however, as males
By transferring mouse aged hematopoietic stem cells (aged HSCs) to the environment of young mice (bone marrow niche), it was demonstrated that the pattern of stem cell gene expression was rejuvenated to that of young hematopoietic stem cells. On the other hand, the function of aged HSCs did not recover in the young bone marrow

Recent analyses indicate that pregnant women and newborns may face elevated risks of developing more severe cases of COVID-19 following SARS-CoV-2 infection. New research led by investigators at Massachusetts General Hospital (MGH) and published in Cell reveals lower than expected transfer of protective SARS-CoV-2 antibodies via the placenta from mothers who are infected in the
Using genetic data from nearly 30,000 people, Mount Sinai researchers have built risk scores from a combination of datasets representing distinct ancestral populations that improve prediction of risk for inflammatory bowel diseases (IBD) including Crohn’s disease and ulcerative colitis. The study was published in Gastroenterology on December 24. The researchers found that polygenic risk scores,

COVID-19 antibodies preferentially target a different part of the virus in mild cases of COVID-19 than they do in severe cases, and wane significantly within several months of infection, according to a new study by researchers at Stanford Medicine. The findings identify new links between the course of the disease and a patient’s immune response.

Tohoku University scientists have, for the first time, provided experimental evidence that cell stickiness helps them stay sorted within correct compartments during development. How tightly cells clump together, known as cell adhesion, appears to be enabled by a protein better known for its role in the immune system. The findings were detailed in the journal

Jean Lengenfelder, PhD, of Kessler Foundation, received a two-year $168,001 grant from the New Jersey Commission on Brain Injury Research to study the impact of traumatic brain injury (TBI) on the ability of children to reliably process the emotions of others. Children with TBI often struggle with social interaction and relationships, even years after their
In the ongoing coronavirus disease 2019 (COVID-19) pandemic, much research has focused on the role of neutralizing antibodies in countering infection by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Most of these studies have been based on genome sequencing, showing matches between the Hypervariable Region (HVR) and the antigen’s receptor-binding domain (RBD). The results have
People walk past the closed entrance of the Eurostar terminal at Brussels South railway station after Britain’s European neighbors began closing their doors to travelers from the United Kingdom amid alarm about a rapidly spreading strain of coronavirus, in Brussels, Belgium December 21, 2020.

When a person has an infection, the body activates immune responses to fight it. IFNγ is an inflammatory molecule produced by the immune system that helps fight infections. However, long-term exposure to IFNγ has undesirable consequences – it irreversibly exhausts blood stem cells, the progenitors of all blood cells, including immune cells, by triggering their
Workers at Garfield Medical Center in suburban Los Angeles were on edge as the pandemic ramped up in March and April. Staffers in a 30-patient unit were rationing a single tub of sanitizing wipes all day. A May memo from the CEO said N95 masks could be cleaned up to 20 times before replacement. Patients
