Criticality in morphogenesis
Study turns parasite invasion theory on its head
Current thinking on how the Toxoplasma gondii parasite invades its host is incorrect, according to a study published today in Nature Methods describing a new technique to knock out genes. The findings coul ...
Novel approach to gene regulation can activate multiple genes simultaneously
By creating a powerful new gene regulation system called CRISPR-on, Whitehead Institute researchers now have the ability to increase the expression of multiple genes simultaneously and precisely manipulate each gene's expression ...
Planting a new perspective on climate research
(Phys.org) —A study on the mechanisms of how plants respond and adapt to elevated levels of carbon dioxide (CO2) and higher temperatures has opened a new perspective in climate research. Lead researcher ...
Developing microbial cell factories by employing synthetic small regulatory RNAs
A Korean research team led by Distinguished Professor Sang Yup Lee at the Department of Chemical and Biomolecular Engineering, Korea Advanced Institute of Science and Technology, reported that synthetic small RNA can be employed ...
Protein strongest just before death
(Phys.org)—Researchers at Michigan State University have discovered a protein that does its best work with one foot in the grave.
Humans, chimpanzees and monkeys share DNA but not gene regulatory mechanisms
Humans share over 90% of their DNA with their primate cousins. The expression or activity patterns of genes differ across species in ways that help explain each species' distinct biology and behavior.
Metals in the genetic forge: Detailed views of RNA splicing
Scientists at Yale University have described in the greatest detail yet aspects of the chemical processes by which RNA carries out the expression of our genes.
Ethylene of no effect: Why peppers do not mature after picking
(Phys.org) -- The plant hormone ethylene lets green tomatoes ripen even after the harvest, whereas the closely related chili peppers show no such effect. Researchers from the Max-Planck-Institute of Molecular ...
Men can rest easy -- sex chromosomes are here to stay
Fears that sex-linked chromosomes, such as the male Y chromosome, are doomed to extinction have been refuted in a new genetic study which examines the sex chromosomes of chickens.
Study reports novel drug technology that boosts therapeutic proteins
(PhysOrg.com) -- A Miller School-led research team has created a groundbreaking drug technology platform that enables the body to increase its protein levels, a novel invention that potentially could usher in treatment for ...
Breakthrough in the production of flood-tolerant crops
As countries such as Pakistan, Bangladesh, Vietnam and parts of the United States and United Kingdom have fallen victim to catastrophic flooding in recent years, tolerance of crops to partial or complete submergence ...
Apple peel makes mice mighty
For Popeye, spinach was the key to extra muscle. For the mice in a new University of Iowa study, it was apples, or more precisely a waxy substance called ursolic acid that's found in apple peel.
From gene to protein: Gene expression quantification offers new insights
How do genes control us? This fundamental question of life still remains elusive despite decades of research. Genes are blueprints for proteins, but it is the proteins that actually carry out vital functions in the body for ...
