One of the biggest challenges in cancer research is understanding why some tumor cells become especially aggressive, invasive and resistant to treatment. Scientists have increasingly linked these ...

When the world goes bad, some plants do something astonishing. They can’t run or hide, nor can they do much about changing ...

Confocal microscopy is performed with nuclear reporters and stains, nuclear segmentation with ilastik is conducted, and a machine learning method is used to classify the ploidy of each nucleus. Colors ...

Assistant Professor of Biology Vicki Losick admits she harbors a desire to change the world a little bit. “I want to make ‘polyploidy’ a household word,” Losick said in her Higgins Hall office, next ...

Biologists may have pinpointed for the first time the mechanism responsible for cell polyploidy, a state in which cells contain more than two paired sets of chromosomes. An international team of ...

Unlike humans, many plants have more than two sets of chromosomes. This trait may help them adapt to environmental upheaval, such as climate change.

For decades, scientists have struggled to untangle the genetic complexity of crops with multiple chromosome sets. Now, researchers have unveiled a cost-effective sequencing method, dpMIG-seq, that ...

Scientists have long known that some cells in a given tissue undergo a process of duplicating their entire genome without dividing – a process called endopolyploidy, where cellular ploidy is the copy ...

Many flowering plants have duplicated genomes, which could have helped them evolve to deal with extreme stress in times of ...

For animals, inheriting more than the usual two copies of DNA is usually a very bad thing. It can happen when two sperm fertilize one egg, or when sexual cell division errs, leaving a sperm or an egg ...
