Engineers model mutations causing drug resistance

Whether it is a drug-resistant strain of bacteria, or cancer cells that no longer react to the drugs intended to kill them, diverse mutations make cells resistant to chemicals, and “second generation” approaches are needed. Now, a team of Penn State engineers may have a way to predict which mutations […]

The growth of an organism rides on a pattern of waves

Study shows ripples across a newly fertilized egg are similar to other systems, from ocean and atmospheric circulations to quantum fluids. When an egg cell of almost any sexually reproducing species is fertilized, it sets off a series of waves that ripple across the egg’s surface. These waves are produced […]

Identification of an existing Japanese pancreatitis drug, Nafamostat, which is expected to prevent the transmission of new coronavirus infection (COVID-19)

Nafamostat mesylate (brand name: Fusan), which is the drug used to treat acute pancreatitis, may effectively block the requisite viral entry process the new coronavirus (SARS-CoV-2) uses to spread and cause disease (COVID-19). The University of Tokyo announced these new findings on March 18, 2020. According to the new research, […]

Research reveals why some prostate cancers are more aggressive

Researchers at the University of East Anglia have discovered why some prostate cancers are more aggressive, spread to different parts of the body, and ultimately cause death. It is hoped that the discovery could transform patient treatment. The findings come after the same team developed a test that distinguishes between […]

New understanding of immune modulator interleukin-2 guides drug discovery

The signaling molecule interleukin-2 (IL-2) has long been known to have powerful effects on the immune system, but efforts to harness it for therapeutic purposes have been hampered by serious side effects. Now researchers have worked out the details of IL-2’s complex interactions with receptor molecules on immune cells, providing […]

Parkinson’s disease linked to gene targeted by blue-green algae toxin

Scientists have discovered a possible link between Parkinson’s disease and a gene impacted by a neurotoxin found in blue-green algae. University of Queensland scientist Dr Jacob Gratten said the findings increased the understanding of the environmental risk factors of Parkinson’s disease. “We looked for a link between Parkinson’s and changes in the human […]

Trajectories of Exercise and Mortality in Late Life

Greater physical activity correlates well with lower mortality in later life. Given the way that human data is collected, and the way in which epidemiological studies are carried out, it is hard to determine causation, however. Is it that exercise is protective, or is it that more robust people both live longer and exercise […]

Stem Cells and Nerves Interact in Tissue Regeneration and Cancer Progression

Researchers at the University of Zurich show that different stem cell populations are innervated in distinct ways. Innervation may therefore be crucial for proper tissue regeneration. They also demonstrate that cancer stem cells likewise establish contacts with nerves. Targeting tumour innervation could thus lead to new cancer therapies. Stem cells […]

Study Finds Disease Causing Repeats Help Human Neurons Function

By focusing on the biology of healthy nerve cells, new research finds repeats in a gene, which causes Fragile X Syndrome, regulates how and when proteins are made in neurons. Over half of our genomes are made of repeating elements within DNA. In rare cases, these repeats can become unstable […]

The Two Way Relationship Between Cellular Senescence and Cancer in Bone Marrow

Cells become senescent in response to a variety of circumstances. The vast majority are cases of replicative senescence, somatic cells reaching the Hayflick limit. Cell damage and toxic environments also produce senescence, and senescent cells are also created as a part of the wound healing process. A senescent cell ceases replication and begins to secrete inflammatory and pro-growth […]

Bacteria potentially involved in the development of Type 2 diabetes

Bacteria may be involved in the development of Type 2 diabetes, according to a study published in Nature Metabolism by researchers from McMaster University, Université Laval and the Québec Heart and Lung Institute. The authors found that the blood, liver, and certain abdominal fat deposits in diabetics have a different […]

Scientists program cells to carry out gene-guided construction projects

Stanford researchers have developed a technique that reprograms cells to use synthetic materials, provided by the scientists, to build artificial structures able to carry out functions inside the body. “We turned cells into chemical engineers of a sort, that use materials we provide to construct functional polymers that change their […]

NIH study provides genetic insights into osteosarcoma in children

A study by researchers at the National Cancer Institute (NCI), part of the National Institutes of Health, offers new insight into genetic alterations associated with osteosarcoma, the most common cancerous bone tumor of children and adolescents. The researchers found that more people with osteosarcoma carry harmful, or likely harmful, variants […]

Urine Test Can Detect Likelihood of Kidney Transplant Rejection

A simple urine test can diagnose and predict acute rejection in kidney transplants, leading to an opportunity for earlier detection and treatment, according to a new study by researchers at UC San Francisco.

Researchers find key to keep working memory working

Working memory, the ability to hold a thought in mind even through distraction, is the foundation of abstract reasoning and a defining characteristic of the human brain. It is also impaired in disorders such as schizophrenia and Alzheimer’s disease. Now Yale researchers have found a key molecule that helps neurons […]

Curbing Chemo

Being diagnosed with cancer, one of the world’s most enduring and undiscriminating killers, is distressing enough. But making it a doubly cruel blow is the fact that undergoing one of its most effective treatments, chemotherapy, can itself be utterly debilitating, and even life-threatening. Worldwide, anywhere from 60-80% of patients treated, […]

Reduced Calorie Intake and Periodic Fasting Independently Contribute to the Benefits of Calorie Restriction

Researchers here make the point that calorie restriction studies in animals are also introducing a strong component of time restricted feeding, as animals tend to be fed once a day. Studies of intermittent fasting without calorie reduction have shown that this can produce a similar set of metabolic responses to a reduced calorie intake. […]

Using “organs-on-a-chip” to model complicated diseases

A new approach reveals how different tissues contribute to inflammatory diseases such as ulcerative colitis. MIT biological engineers have created a multi-tissue model that lets them study the relationships between different organs and the immune system, on a specialized microfluidic platform seeded with human cells. Using this type of model, […]

New technique ‘prints’ cells to create diverse biological environments

Like humans, cells are easily influenced by peer pressure. Take a neural stem cell in the brain: Whether this cell remains a stem cell or differentiates into a fully formed brain cell is ultimately determined by a complex set of molecular messages the cell receives from countless neighbors. Understanding these […]
