How a protein keeps gene clusters quiet in the cell nucleolus
In a discovery that sheds light on the complex mechanisms of gene regulation, scientists at EPFL have uncovered a critical role for the protein ZNF274 in keeping certain gene clusters turned off by anchoring them to the cell nucleolus. The study is p.....»»
How iron and metabolic constraints can aid gene discovery for photosynthesis and biofuel production
The single-cell green alga Chromochloris zofingiensis is an emerging model organism for photosynthesis and metabolism research. Previous research has shown that with the addition of glucose, Chromochloris zofingiensis shuts off photosynthesis, rerout.....»»
Elucidating the mechanism of cell division during plant self-healing
When the stem of a plant is injured, the surrounding cells proliferate to repair and fuse the damaged tissue, eventually restoring function. This self-healing property is utilized in grafting techniques to propagate fruit and vegetable plants......»»
Scientists identify structural basis of stitched-together protein complexes that recycle most proteins in cells
Scientists at Sanford Burnham Prebys have developed a clearer picture of how crucial machinery in the human cell's recycling process for obsolete and misshapen proteins—known as proteasomes—are formed......»»
Affordable iron catalysts offer a sustainable route to prized Z-alkenes
Chemists from the National University of Singapore (NUS) have developed an iron-catalyzed method that overcomes a significant challenge in the sustainable synthesis of trisubstituted Z-alkenes by inserting two alkyl chemical groups into a type of com.....»»
Lignin-based sunscreen offers natural and high-performance UV protection
In a significant breakthrough for the cosmetics industry, researchers have developed a new type of sunscreen using lignin, a naturally abundant polymer, and titanium dioxide (TiO2). The study, led by Yarong Li and Zhiguang Tang, was published in the.....»»
Shedding light on a decades-old protein sorting mystery
Christian de Caestecker, a Ph.D. student in the lab of Ian Macara, Louise B. McGavock Professor and chair of the Department of Cell and Developmental Biology, has proposed and validated a mechanism that addresses a decades-old mystery surrounding epi.....»»
Scientists create model of holographic dark energy that is no longer unstable
In 1998, scientists discovered that our universe expands with acceleration, and in order to explain this effect, the concept of dark matter was introduced. This is a special type of energy that fills up all of existing space-time but is impossible to.....»»
Are branch faults the "on-ramps" that lead to great continental transform earthquakes?
The five largest continental transform earthquakes since 2000 all originated on a branch of the main fault—and two researchers predict that the next great earthquake of this type will also get its start on a branch or splay fault......»»
Advancing synthetic Ephedra-type alkaloids with a two-step enzymatic approach
Ephedra-type alkaloids, a class of naturally occurring compounds derived from plants in the genus Ephedra, have long held interest in the pharmaceutical industry due to their stimulant and airway widening effects. These alkaloids are used for the tre.....»»
Gelatins from antlers, skin and bones of sika deer exhibit antioxidant activity, study finds
A research group discovered that gelatins from the antlers, skin, and bones of sika deer (Cervus Nippon) exhibit antioxidant activity......»»
Drone footage provides new insight into gray whales" acrobatic feeding behavior
Drone footage captured by researchers in Oregon State University's Marine Mammal Institute is offering new insight into the acrobatics undertaken by gray whales foraging in the waters off the coast of Oregon......»»
Bacterial "flipping" allows genes to assume different forms
Imagine being one cartwheel away from changing your appearance. One flip, and your brunette locks are platinum blond. That's not too far from what happens in some prokaryotes, or single-cell organisms, such as bacteria, that undergo something called.....»»
GM, Piston plot hydrogen fuel cell factory in Detroit
GM and Piston Automotive are plotting a hydrogen fuel cell factory in Detroit, GM's first standalone plant for fuel cell production......»»
Cryo-ET study provides viral close-up of HTLV-1, the "overlooked cousin of HIV"
In collaboration with the University of Minnesota and Cornell University, Martin Obr and Florian Schur from the Institute of Science and Technology Austria (ISTA) provide new details into the architecture of HTLV-1 (Human T-cell Leukemia Virus Type 1.....»»
SSD vs. HDD: What’s the difference, and which drive type is best?
What's the difference between SSD vs. HDD? What kind of drive is right for you is going to depend on your situation, but we'd suggest you get at least one SSD......»»
New rules could help child welfare systems treat parents with disabilities more fairly
Parents with any kind of disability are much more likely to have some type of interaction with the child welfare system than other parents. This means they are more likely than other parents to be reported for child abuse and neglect and more likely.....»»
Tree frog tadpoles have a unique way of not contaminating their water supply: Not pooping
The Eiffinger's tree frog (Kurixalus eiffingeri), found on Ishigaki and Iriomote islands in Japan, has a unique biological adaptation: its tadpoles do not defecate during their early developmental stages. This finding by researchers at Nagoya Univers.....»»
New Zealand scientists discover ghostly "spookfish"
Scientists in New Zealand said Tuesday they have discovered a new species of "ghost shark", a type of fish that prowls the Pacific Ocean floor hunting prey more than a mile down......»»
