Researchers at Massachusetts General Hospital successfully developed implantable, bioengineered rat kidneys that produced urine and functioned in living animals. The approach uses donor organs stripped of cells, repopulated with human or animal cells, and cultured to mimic native organ structure and function.
Researchers have successfully treated metastatic lung cancer using cryoablation, a minimally invasive procedure that uses frozen balls of ice to kill cancerous tumors. The treatment has shown promising results, with 100% effectiveness in killing tumors at three-month follow-up and prolonged survival for patients.
Researchers at CWRU School of Medicine discover a technique to directly convert skin cells into myelinating brain cells, potentially treating multiple sclerosis and cerebral palsy. The new method enables rapid production of functional oligodendrocytes, which provide insulation for neurons.
A new 1000-year Antarctic Peninsula climate reconstruction reveals a near-tenfold increase in summer ice melt since the mid-20th century. This intensification has important implications for ice instability and sea level rise in a warming climate.
A gene sequencing project has identified mutations responsible for more than half of a subtype of childhood brain tumor that takes a high toll on patients. The study found that the tumors are susceptible to drugs already in development, offering new hope for treatment.
In a study presented at the Society of Interventional Radiology's Annual Scientific Meeting, researchers found that drug-coated stents can effectively treat critical limb ischemia by keeping clogged leg arteries open. The treatment resulted in a significant reduction in amputations and improved quality of life for patients.
A new electrical pulse treatment called irreversible electroporation (IRE) has been shown to be safe and effective for treating complex cancers without harming healthy tissue. IRE precisely perforates cancer cells, posing fewer risks to vital structures.
Researchers at Mount Sinai identify 14 genetic targets associated with heart rate, which could lead to new drugs for treating cardiovascular disease. The study's findings also shed light on the genetic regulation of heartbeats and cardiac conduction disorders.
A large-scale genetic study has identified three new genetic variants linked to obesity in individuals of African descent, also influencing BMI in the US population with no known African ancestry. The study suggests that these variants are present in nearly all previously identified European-derived obesity genes.
Researchers at the University of Arizona have developed a new chemical process that transforms waste sulfur into a lightweight plastic, which may improve batteries for electric cars and other applications. The new plastic has great promise as something that can be produced easily and inexpensively on an industrial scale.
Scientists discovered that certain bacteria require parts of the CRISPR system to stay infectious, using it to shut off a gene that triggers detection by the immune system. This finding could accelerate vaccine development, but also highlights the dangers of defensive tools being co-opted for stealth.
A new study reveals that correcting PSA levels for genetic variants can significantly reduce unnecessary biopsies and false complacency. By tailoring screening levels to an individual's genetic makeup, the risk of prostate cancer can be more accurately assessed. This approach has the potential to prevent up to 15% to 20% of biopsies.
Engineers at UC San Diego have developed nanosponges that can neutralize a wide range of pore-forming toxins, including those produced by MRSA, E. coli, and poisonous snakes and bees. The nanosponges are designed to absorb toxins and divert them away from their cellular targets, with promising results in mouse studies.
Cryoneurolysis, a new interventional radiology treatment, safely short circuits chronic pain caused by nerve damage. After treatment, patients experienced significant lasting pain relief and were able to reduce or eliminate pain medication use.
Researchers analyzed a new ice core from Antarctica, finding that recent glacier changes are at the 'upper bound' of normal. The study suggests that rapid thinning and warming in the region cannot be confidently attributed to human-caused global warming.
The tulip tree's mitochondrial genome has remained largely unchanged since the dinosaurs, providing a 'molecular fossil' with preserved ancestral gene clusters. The slow mutation rate allows researchers to estimate the ancestral angiosperm mitochondrial genome contained 41 protein genes.
As malaria incidence declines, it becomes increasingly concentrated in specific locations and groups, making targeted approaches crucial. Effective identification and treatment of infected individuals, particularly migrant workers and mobile populations, are essential for successful malaria elimination.
New research shows that reducing emissions of short-lived pollutants like methane, tropospheric ozone, and hydrofluorocarbons can temporarily forestall the rate of sea level rise. This could lower the threat to coastal cities by stabilizing carbon dioxide concentrations in the atmosphere.
Stenting of completely blocked mesenteric arteries can safely restore blood flow to the bowel and resolve patients' symptoms with few complications. This minimally invasive treatment is a game-changer for elderly patients and those with peripheral arterial disease, offering less risk and faster recovery time.
