A new study details the latest efforts to predict traits in corn based on genomics and data analytics. The data management technique could help to “turbo charge” the seemingly endless amount of genetic stocks contained in the world’s seed banks, leading to faster and more efficient development of new crop varieties.
Darwin’s theory of evolution should be expanded to include consideration of a DNA stability “energy code” – so-called “molecular Darwinism” – to further account for the long-term survival of species’ characteristics on Earth, according to Rutgers scientists. The iconic genetic code can be viewed as an “energy code” that evolved by following the laws of thermodynamics (flow of energy), causing its evolution to culminate in a nearly singular code for all living species, according to the Rutgers co-authored study in the journal Quarterly Review of Biophysics.
Red algae have persisted in hot springs and surrounding rocks for about 1 billion years. Now, a Rutgers-led team will investigate why these single-celled extremists have thrived in harsh environments – research that could benefit environmental cleanups and the production of biofuels and other products.
Researchers generated genome sequences for nearly 600 green millet plants and released a very high-quality reference S. viridis genome sequence Analysis of these plant genome sequences also led them to identify for the first time in wild populations a gene related to seed dispersal.
A study finds that cancer mutations occur in distinct patterns based on the 3D structure of the genome and the underlying cause of the mutation. This helps us to understand cancer better and may lead to new treatment approaches.
Researchers have found at least 10 distinct “hotspot” mutations in more than 80% of randomly selected SAR-CoV-2 sequences from six countries, and these genome hotspots – seen as “typos” that can occur as the virus replicates during cellular division – could have a significant impact in the fight against the COVID-19 pandemic.
From Weight Watchers to wearable tech – wherever we look, there are messages encouraging us to stay fit and healthy. But diets and training methods aside, when it comes to heart health, research from the University of South Australia shows that a far more personalised approach is needed…and it all starts with your genes.
An Iowa State University scientists contributed to a global effort to assemble the genome of the tuatara, a rare reptile species native to New Zealand. The tuatara genome sheds light on the genomic structure of a huge range of species, including humans.
Scientists from the University of Adelaide and South Australian Museum have collaborated with Otago University, New Zealand and a global team to sequence the genome of the tuatara – a rare reptile whose ancestors once roamed the earth with dinosaurs.
UC Santa Cruz researchers played a crucial role in early planning of the human genome project, in assembling the genome sequence, developing tools for its visualization and ensuring it remained in the public domain. They continue to have a major role in the ongoing analysis of the human genome.
When Pulitzer Prize and Grammy award winner Kendrick Lamar rapped “I got millions, I got riches buildin’ in my DNA,” he almost certainly wasn’t talking about the humble tomato. But a new study unveiling more than 230,000 DNA differences across 100 tomato varieties which will allow breeders and scientists to engineer larger, juicier, more profitable plants, proves that tomatoes indeed have riches buildin’ in their DNA, too.
An analysis of genetic studies covering 266,000 women has revealed 32 new sites on the human genome where variations in DNA appear to alter the risks of getting breast cancer.
• Newly discovered gene variant in Peruvian populations is powerfully linked with height
• Five percent of Peruvians carry the variant, which originates exclusively from Native American populations
• The variant occurs on a gene that, when mutated, causes Marfan syndrome, a condition marked by connective tissue abnormalities, including serious cardiovascular problems
• The newly discovered variant is not associated with disease and may confer adaptive evolutionary advantage to populations that carry it
The promise of personalized medicine has not fully materialized, say two McMaster researchers, because the full sophistication of the genetic blueprint has a more complex and far-reaching influence on human health than scientists had first realized.
National Eye Institute (NEI) researchers profiling epigenomic changes in light-sensing mouse photoreceptors have a clearer picture of how age-related eye diseases may be linked to age-related changes in the regulation of gene expression. The findings, published online April 21 in Cell Reports, suggest that the epigenome could be targeted as a therapeutic strategy to prevent leading causes of vision loss, such as age-related macular degeneration (AMD).
The Weizmann Institute’s Prof. Ron Milo and colleagues at Caltech and Berkeley used his biomass-analyzing techniques to sort the mass of coronavirus data, with interesting results. For example, they found that the coronavirus mutation accumulation rate is relatively slow, which is good news for vaccines

Scientists at Princess Margaret Cancer Centre have identified the drivers of a crucial gene involved in prostate cancer, revealing new targets for drug design.
Researchers identified a set of cis-regulatory elements – namely enhancers and the promoter – in the non-coding region of the genome, which affect the expression of FOXA1 gene, one of the major drivers or oncogenes involved in prostate cancer development.
Domesticated rice has fatter seed grains with higher starch content than its wild rice relatives — the result of many generations of preferential seed sorting and sowing. But even though rice was the first crop to be fully sequenced, scientists have only documented a few of the genetic changes that made rice into a staple food for more than half the world’s population.
Science Snapshots from Berkeley Lab
Genes from a virus that was stitched into the human genome thousands of years ago are active, producing proteins in the human brain and other tissues, new research suggests. The finding might help explain why people who inherit this “fossil virus” appear to have a higher risk of developing neurodegenerative diseases such as multiple sclerosis and Alzheimer’s.
You’d think that losing 25 percent of your genes would be a big problem for survival. But not for red algae, including the seaweed used to wrap sushi. An ancestor of red algae lost about a quarter of its genes roughly one billion years ago, but the algae still became dominant in near-shore coastal areas around the world, according to Rutgers University–New Brunswick Professor Debashish Bhattacharya, who co-authored a study in the journal Nature Communications.
Bourbon isn’t bourbon without the mighty white oak. Distillers have been aging bourbon in oak barrels as far back as the Roman Empire. Oak barrels give bourbon its unique caramel, vanilla, nutty and toasted flavors. Kentucky distillers rely especially on the white oak. But what if disease hits the species? How would industry professionals protect it? The University of Kentucky College of Agriculture, Food and Environment is partnering with Maker’s Mark Distillery Inc. in Loretto, Kentucky, and Independent Stave Company to research the DNA of the white oak.
An international team of scientists lead by the Joint Genome Institute has developed a genetic engineering tool that makes producing and analyzing microbial secondary metabolites – the basis for many important agricultural, industrial, and medical products – much easier than before, and could even lead to breakthroughs in biomanufacturing.
