Engineered telomerase RNA offers temporary boost to telomere length in human stem cells

Much the way the caps on the ends of a shoelace prevent it from fraying, telomeres - regions of repetitive DNA sequences and a protein structure - protect the tips of chromosomes from damage.

High-speed 3D imaging microscope captures whole organism dynamics in real time

Researchers have developed a high-speed 3D imaging microscope that can capture detailed cell dynamics of an entire small whole organism at once.

Helicobacter pylori eradication therapy linked to increased risk of reflux oesophagitis

The management of Helicobacter pylori (H. pylori), a globally prevalent gastric pathogen, has long been centered on its eradication to prevent peptic ulcers, gastric malignancies, and related gastrointestinal complications.

Sex and residual enzyme activity primarily determine clinical course in Chinese Fabry patients

Fabry disease in mainland China is now mapped through the largest single-centre cohort to date, clarifying how α-galactosidase A deficiency, genotype and sex jointly sculpt the clinical spectrum.

Dual epigenetic marks found to regulate cell identity

Shedding light on what determines how cells become what they are meant to be-nerves, bone, muscles, etc.-can also help researchers understand how diseases develop when these biological programs break down.

Gene editing restores hearing and balance in adult mice with DFNA41 deafness

Zheng-Yi Chen, DPhil, associate scientist at the Eaton-Peabody Laboratories, and Ines and Fredrick Yeatts Chair in Otolaryngology, at Mass Eye and Ear, is the senior and co-corresponding author of a paper published in the Journal of Clinical Investigation, "Single Dose Genome Editing Therapy Rescues Auditory and Vestibular Functions in Adult Mice with DFNA41 Deafness."

Brain organoids reveal early changes in familial Alzheimer’s disease

Alzheimer's disease (AD) is the most common neurodegenerative disease in older people, affecting up to 1 in 20 individuals aged 65 and above. In addition to environmental and lifestyle factors, genetic mutations can predispose an individual to AD and some rare forms of inherited "familial" AD (fAD) are caused by known genetic mutations, with these affected individuals developing AD with high probability and at relatively young age.

Triglycerides identified as direct cause of abdominal aortic aneurysms

High levels of triglycerides, the most common type of fat in the body and the foods we eat, directly cause abdominal aortic aneurysms, according to a study in mouse models led by Michigan Medicine.

Rare immune mutation unlocks universal antiviral protection

For a few dozen people in the world, the downside of living with a rare immune condition comes with a surprising superpower-the ability to fight off all viruses.

Scaffold-free cellular spheroids generate integrated osteochondral grafts

A new study in the peer-reviewed journal Tissue Engineering, Part A demonstrates the potential to produce cellular spheroids, from a clinically relevant embryonic stem cell derived mesenchymal stem cell (ES-MSC) source, to generate scaffold-free chondrogenic or osteochondrogenic graft tissues.

Early use of risdiplam in newborns with SMA shows improvements in motor development

Spinal muscular atrophy (SMA) is a rare genetic condition that causes progressive muscle weakness, which, when untreated, prevents infants with the most severe form from gaining motor development - never gaining the ability to sit - and typically leads to death before 2 years of age.

High-dose vitamin D in pregnancy likely cuts childhood wheeze risk, but infant supplements fall short

A Cochrane review of 18 randomized trials found that high-dose vitamin D during pregnancy likely reduces the risk of childhood wheeze, a key early symptom of asthma. However, vitamin D supplementation in infants and young children showed uncertain benefits for asthma prevention.

Disrupting dopamine pathway stops threadworms from burrowing into the skin

Threadworms, which are a type of parasitic nematode, spend a lot of time crawling around on human skin, poking and prodding to find the best place for entry before burrowing in.

New research sheds light on what makes the human brain unique

Research from scientists at University of California San Diego School of Medicine have shed new light on an age-old question: what makes the human brain unique?

New mouse model reveals key role of osteocytes in osteogenesis imperfecta

Osteogenesis imperfecta (OI) refers to a group of rare genetic bone disorders that results in the formation of fragile bones. In patients with OI, the matrix that makes up the bone has been found to be abnormal, leading to an increased risk of fractures.

Leading organizations announce research initiative to uncover why ALS affects high-performing populations

Answer ALS, in collaboration with ALS Therapy Development Institute (ALS TDI) and Augie's Quest, today announced plans to launch Champion Insights, an ambitious research initiative designed to uncover critical genetic and metabolic mechanisms that may explain the significantly higher incidence of amyotrophic lateral sclerosis (ALS) among endurance athletes, military service members, and potentially other high-performing populations.

New discovery in spinal cord neurons offers hope for breathing recovery

Today about 300,000 people nationally living with a spinal cord injury and with respiratory complications being the most common cause of illness and death, according to the Christopher & Dana Reeve Foundation.

mRNA vaccine shows potent efficacy in gastric cancer

Gastric cancer is one of the leading causes of cancer-related mortality worldwide, and peritoneal metastasis, wherein the cancer spreads to the peritoneum or the lining of the abdominal cavity, represents the most common form of recurrence after gastric cancer surgery.

Researchers find CFI deficiency alarmingly high in old order Amish

Researchers from Children's Hospital of Philadelphia (CHOP) and the Clinic for Special Children found that complement factor I (CFI) deficiency, an ultra-rare genetic disorder that can cause debilitating neuroinflammation, is more than 4500 times more likely to be found in individuals of Old Order Amish ancestry than the rest of the global population.
