Grafting is one of the key technologies to overcome the obstacles of continuous cropping, and improve crop yield and quality. However, the symbiotic incompatibility between rootstock and scion affects the normal growth and development of grafted seedlings after survival. https://phys.org/news/2024-01-molecular-mechanism-graft-incompatibility-cucumberpumpkin.html Molecular & Computational biology Wed, 17 Jan 2024 12:57:02 EST news624718621 You're likely familiar with the idea of the sterile mule: a hybrid animal born of a horse and a donkey that is unable to breed. https://phys.org/news/2022-01-hybrid-fish-nature-mismatched-genes.html Plants & Animals Mon, 10 Jan 2022 14:00:01 EST news561043644 Species typically evolve over the course of eons, but researchers at the University of Minnesota have developed a way to do it in less than a year. A team of scientists led by Mike Smanski, Ph.D., in the College of Biological Sciences (CBS) has generated speciation events in fruit flies so that engineered strains can reproduce normally with each other, but mating with unmodified flies results in non-viable offspring. https://phys.org/news/2020-09-speciation-events-insects-pests.html Ecology Tue, 08 Sep 2020 16:28:08 EDT news518801281 A Vanderbilt team took the next leap forward in using a little-known bacteria to stop the spread of deadly mosquito-borne viruses such as Zika and dengue. https://phys.org/news/2018-04-zika-dengue-boost-reliable-bacteria.html Cell & Microbiology Mon, 23 Apr 2018 15:00:05 EDT news443680904 Scientists have identified a virus that can weaken the ability of a fungus to avoid pairing with other incompatible fungi, according to new research published in PLOS Pathogens. By promoting fungal pairing, the virus could aid transmission of additional unrelated viruses between fungi. https://phys.org/news/2017-03-virus-barriers-incompatible-fungi.html Biotechnology Thu, 23 Mar 2017 14:00:03 EDT news409493496 Wolbachia is the most successful parasite the world has ever known.

When mutations occur in each, they can become incompatible, leading to disease. To increase understanding of such illnesses, scientists at Brown University and Indiana University have traced one example in fruit flies down to the individual errant nucleotides and the mechanism by which the flies become sick. https://phys.org/news/2013-02-cell-genomes-collide.html Biotechnology Tue, 05 Feb 2013 11:28:07 EST news279286075 New research suggests that dual-identity immigrants—first-generation immigrants and their descendants who identify with both their cultural minority group and the society they now live in—may be more prone to political radicalism if they perceive their two cultural identities to be incompatible. https://phys.org/news/2013-01-conflicting-cultural-identities-foster-political.html Social Sciences Wed, 30 Jan 2013 09:23:54 EST news278760227 (PhysOrg.com) -- A team of researchers from the CNST and ITL has simultaneously changed the color and shape of a single photon, the smallest unit of light. https://phys.org/news/2011-10-photon.html Optics & Photonics Thu, 06 Oct 2011 07:01:49 EDT news237103277 What has made the Internet such a success could help change the way high-dollar and hazardous packages are tracked, according to Randy Walker of the Department of Energy's Oak Ridge National Laboratory. https://phys.org/news/2011-06-ornl-package-tracking-social-media.html Engineering Mon, 13 Jun 2011 14:57:34 EDT news227195834 Blood group incompatibility between Henry VIII and his wives could have driven the Tudor king's reproductive woes, and a genetic condition related to his suspected blood group could also explain Henry's dramatic mid-life transformation into a physically and mentally-impaired tyrant who executed two of his wives. https://phys.org/news/2011-03-puzzle-henry-viii.html Other Thu, 03 Mar 2011 15:10:36 EST news218387401 An individual with Down syndrome and a male calico cat have one thing in common -- each has an extra chromosome. For animals, most instances of an extra chromosome result in birth defects or even death, but plants are another matter entirely. Many plants are able to survive the presence of an extra copy of their entire genome (known as polyploidy) and are often even more vigorous as a result. For plants, the process of polyploidy often results in a new species, making it an important mechanism in evolution. In fact, over 80% of plants may be a product of polyploidy. https://phys.org/news/2009-09-youve-genes-chromosome.html Biotechnology Mon, 14 Sep 2009 16:10:02 EDT news172162573
