Here’s What’s Next for Pig Organ Transplants
2022 was a breakthrough year for xenotransplantation, a procedure that could be a lifeline for patients in desperate need of a donor......»»
Fungal transplants from close relatives help endangered plants fight off disease
For the endangered Hawaiian plant Eugenia koolauensis, fungi could be both its demise and its savior. The fungal pathogen myrtle rust (Austropuccinia psidii) has been devastating populations of the endemic tree, along with many other native and culti.....»»

Newly discovered two-cell color detection system of lamprey is clue to the evolution of color vision
Using the lamprey, researchers from Japan analyzed the photosensory mechanism of the pineal organ, also called the pineal gland, in non-mammalian vertebrates and discovered a novel mechanism of pineal color discrimination (two-cell system) in which t.....»»
Food claiming to have "wild mushrooms" rarely do
Harvesting wild mushrooms requires an expert eye to distinguish between the delicious and the inedible. Misidentification can have a range of consequences, from a disgusting taste and mild illness to organ failure and even death. Culinary wild mushro.....»»
New imaging tool visualizes cell functions in a microphysiological system
A microphysiological system (MPS), also known as an organ-on-a-chip, is a 3D organ construct using human cells that help reveal how organs respond to drugs and environmental stimuli......»»
The FDA OKs an Extra Vaccine Dose for Immunosuppressed People
The federal agency will allow people living with organ transplants, undergoing cancer treatments and taking some medications to get a third shot......»»
Sunlight drives leaf mass area based on spectral composition
Plant leaves is the main organ that converts inorganic carbon into organic carbon. Leaf mass area (the leaf mass per unit area, LMA) characterizes the morphological, physiological and biochemical functions of the leaves, as well as the functions and.....»»
New organ-on-a-chip finds crucial interaction between blood, ovarian cancer tumors
Researchers are pushing organ-on-a-chip devices to new levels that could change the way clinicians approach cancer treatment, particularly ovarian cancer......»»
"Missing self" contributes to organ rejection after transplantation
After kidney transplantation, natural killer cells of the recipient become active because they miss 'self' proteins on donor cells. These cells contribute to organ rejection, in addition to traditional modes of rejection involving T cells and antibod.....»»
Identification of over 200 long COVID symptoms prompts call for UK screening programme
Patients who experience long COVID have reported more than 200 symptoms across 10 organ systems, in the largest international study of 'long-haulers' to date......»»
Mechanical stimuli significantly influence organ growth
In addition to chemical factors, mechanical influences play an important role in the natural growth of human organs such as kidneys, lungs and mammary glands - but also in the development of tumors. Now a research team has investigated the process in.....»»
Study identifies risk factors for severe COVID-19 in individuals with sickle cell disease
New research finds that certain factors, such as a history of severe pain episodes and coexisting organ conditions, increase the risk of severe COVID-19 illness, including hospitalization, in individuals living with sickle cell disease (SCD). Accordi.....»»
A Hospital Algorithm Designed To Predict a Deadly Condition Misses Most Cases
Epic Systems' algorithm for identifying signs of sepsis, an often deadly complication from infections that can lead to organ failure, doesn't work as well as advertised, according to a new study published in JAMA Internal Medicine. The Verge reports:.....»»
Researchers discover how the intestinal epithelium folds and moves by measuring forces
An international team led by Xavier Trepat at IBEC measures the cellular forces in mini-intestines grown in the laboratory, deciphering how the inner wall of this vital organ folds and moves. The study, published in Nature Cell Biology, opens the doo.....»»
Damage control: Plants juggle genome maintenance and growth by being organized
Humans pride themselves on being able to multitask, especially under pressure. But it turns out that we aren't the only ones who are organized: Researchers from Japan have discovered that plants balance genome maintenance with organ growth by organiz.....»»
Genetic base editing treats sickle cell disease in mice
Sickle cell disease leads to chronic pain, organ failure, and early death in patients worldwide. A team has demonstrated a gene editing approach that efficiently corrects the mutation underlying SCD in patient blood stem cells and in mice. This treat.....»»
Scientist identifies signaling underlying organ and limb regeneration
Many salamanders can readily regenerate a lost limb, but adult mammals, including humans, cannot. Why this is the case is a scientific mystery that has fascinated observers of the natural world for thousands of years......»»
Understanding the skin"s defense system
It can be easy to forget that the human skin is an organ. It's also the largest one and it's exposed, charged with keeping our inner biology safe from the perils of the outside world......»»
Skin and immune cells coordinate defenses against assault
As the human body's largest organ, the skin is responsible for protecting against a wide range of possible infections on all fleshy surfaces, from head to toe. So how exactly does the skin organize its defenses against such an array of threats?.....»»
