Could Dad’s Mitochondrial DNA Benefit Hybrids?
Alejandra Manjarrez, PhD | Jan 20, 2022 | 7 min read
Studies have found that organisms can inherit mitochondria from male parents in rare instances, and both theoretical and experimental work hint that this biparental inheritance is more than just a fluke.

By Bob Grant A Theory Blossoms Researchers unfold a key step in the process that tells plants to flower, findings that could one day benefit agriculture. Fluorescent FT protein in the phloem of an Arabidopsis plant. Courtesy of Laurent Corbesier and George Coupland Few acts of nature seem simpler than flowers blooming on the outstretched tips of a plant’s shoots. But the induction of that seemingly simple process baffled pla

FEATUREChallenging Nature © Bill Sanderson/Photo Researchers, Inc. Think only the religious right is anti-science? How about the spiritual left?BY LEE M. SILVERTo be alive as an organic organism on earth, you must have access to water. On most land areas, water availability varies from month to month and year to year. As a result, the form and number of living things is greatly limited. In the Amazon rainforest, however, getting wate

Detecting Tumors from Shed DNA
Douglas Steinberg | May 13, 2001 | 7 min read
Medical institutions across the United States will begin recruiting volunteers next month for a study that its investigators and outside observers describe as groundbreaking. They say it is the first large-scale trial to test the feasibility of using DNA shed by tumors to find early-stage cancer. During the three-year government-funded project, researchers will analyze DNA from stool samples to detect patterns characteristic of colorectal cancer (CRC). The study will have two other notable fe
