How the selfish genes of yeast succeed
New findings from the Stowers Institute for Medical Research uncover critical insights about how a dangerous selfish gene—considered to be a parasitic portion of DNA—functions and survives. Understanding this dynamic is a valuable resource for th.....»»
Novel switch turns genes on/off on cue, a promising step toward safer gene therapy
Just like a doctor adjusts the dose of a medication to the patient's needs, the expression of therapeutic genes, those modified in a person to treat or cure a disease via gene therapy, also needs to be maintained within a therapeutic window. Staying.....»»
Antarctic octopus DNA reveals ice sheet collapse closer than thought
Scientists investigating how Antarctica's ice sheets retreated in the deep past have turned to an innovative approach: studying the genes of octopuses that live in its chilly waters......»»
Examining the relationship between the rate of wound healing, the circadian rhythm and cilium length
Nearly every organism on Earth follows a natural circadian rhythm that is coded by your cell's clock genes, which do exactly as you suspect from the name: regulate your body's rhythm on a 24-hour basis......»»
Researchers discover how cysteine activates a key regulator of cell growth in yeast
Amino acids are the building blocks of life. We obtain them from the food we eat, and the body uses them to make proteins, which in turn are used for growth, development, and a multitude of other functions. However, before the body can build with the.....»»
Unveiling the role of autophagy in metabolism and growth for tomato fruit development
Autophagy, a eukaryotic mechanism for breaking down cellular components, is a vital process in lytic organelles such as vacuoles in yeast and plants, and lysosomes in animals. Research has predominantly focused on the model plant Arabidopsis, reveali.....»»
Scientists engineer bacteria to make two valuable products from plant fiber
We often look to the smallest lifeforms for help solving the biggest problems: Microbes help make foods and beverages, cure diseases, treat waste and even clean up pollution. Yeast and bacteria can also convert plant sugars into biofuels and chemical.....»»
Team discovers relationship between DNA replication timing and how genes fold into 3D structures inside cell nucleus
The intricate process of duplicating genetic information, referred to as DNA replication, lies at the heart of the transmission of life from one cell to another and from one organism to the next. This happens by not just copying the genetic informati.....»»
Expansin genes shown to drive heteroblastic leaves in Ceratopteris chingii
Heteroblasty is a developmental trajectory event in which plants undergo rapid ontogenetic changes in multiple traits, as exemplified by the transition from distinct juvenile to adult leaves. Heteroblastic leaves allow plants to adapt to environmenta.....»»
A bacterial toolkit for colonizing plants
Using a novel experimental approach, Max Planck researchers have discovered a core set of genes required by commensal bacteria to colonize their plant hosts. The findings published in Nature Communications may have broad relevance for understanding h.....»»
Cockroaches can transmit antimicrobial resistance genes between groups
A new paper describes a study of antimicrobial resistance (AMR) transmission among cockroaches, with implications for AMR transmission in humans. The study was published in mSystems......»»

Scott Cooke will become CEO of Toyota Financial Services, the nation's largest captive auto lender, effective Jan. 2, succeeding Mark Templin in the role......»»
Industry veteran Julie Fream to step down as CEO of auto suppliers association
Collin Shaw, the manufacturers association's chief commercial vehicle officer and COO for its Original Equipment Suppliers group, will succeed Fream on April 1......»»
Gene variants that promote having more sex and kids diminish your life span
A literal life-or-death balance, playing out at the level of individual genes. Enlarge / A large family can come with some unfortunate downsides (in addition to that weird cousin). (credit: Oliver Rossi) Analysis of geno.....»»
Study reveals genes that set humans apart from other primates in cognitive ability
An international team led by researchers at the University of Toronto has uncovered over 100 genes that are common to primate brains but have undergone evolutionary divergence only in humans—and which could be a source of our unique cognitive abili.....»»
BorgWarner CFO Kevin Nowlan to retire; Craig Aaron up next
Craig Aaron, BorgWarner's vice president and controller, will succeed Kevin Nowlan, effective March 1. Nowlan will remain with the company in an advisory capacity through April 1......»»
New enzyme allows CRISPR technologies to accurately target almost all human genes
A team of engineers at Duke University have developed a method to broaden the reach of CRISPR technologies. While the original CRISPR system could only target 12.5% of the human genome, the new method expands access to nearly every gene to potentiall.....»»
Being child-free has been deemed "selfish" for decades—the history of this misconception explained
Choosing to be child-free is more common than ever before in some countries, including the US. Many people see not having children an ethical and ecological choice, made to protect the environment, people and other species. Being child-free is about.....»»
Research reveals clever dosage control mechanism of biallelic genes
Have you ever wondered why we carry two copies of each chromosome in all of our cells? During reproduction, we receive one from each of our parents. This means that we also receive two copies, or alleles, of each gene—one allele per chromosome or p.....»»
Clonal fish: Same genes, same environment, different fitness levels
According to current knowledge, individuality is determined by either differences in genome or in the apparent environmental conditions. However, studies show, the paradigm of twin research is currently crumbling......»»
Scientists finally succeed in growing dolomite in the lab by dissolving structural defects during growth
For 200 years, scientists have failed to grow a common mineral in the laboratory under the conditions believed to have formed it naturally. Now, a team of researchers from the University of Michigan and Hokkaido University in Sapporo, Japan have fina.....»»
