Published Disaster-proofing sustainable neighborhoods requires thorough long-term planning
(via sciencedaily.com)
Original source 
Engineers and scientists look at how thoughtful design can reduce a sustainably-designed neighborhood’s energy vulnerability during power disruptions, as well as which design characteristics are needed if and when local populations need to move to shelters. Researchers analyzed the design and energy characteristics of particular kinds of buildings and neighborhoods to assess their vulnerabilities and their access to alternative and renewable energy sources. The authors use several scenarios involving different lengths of power disruption to see which kind of response is most beneficial to the populations affected.
Published When cells go boom: Study reveals inflammation-causing gene carried by millions

Published DNA from discarded whale bones suggests loss of genetic diversity due to commercial whaling
(via sciencedaily.com)
Original source 
Commercial whaling in the 20th century decimated populations of large whales but also appears to have had a lasting impact on the genetic diversity of today’s surviving whales, new research shows.
Published Preventing spread of parasitic DNA in our genomes
(via sciencedaily.com)
Original source 
Researchers have identified a new enzyme called PUCH, which plays a key role in preventing the spread of parasitic DNA in our genomes. These findings may reveal new insights into how our bodies detect and fight bacteria and viruses to prevent infections.
Published Water makes all the difference
(via sciencedaily.com)
Original source 
Water is a major driving force in the formation of separate reaction compartments within cells.
Published A hygiene program for chromosomes
(via sciencedaily.com)
Original source 
Researchers identified and characterized a new cellular compartment in vertebrate cells that might be a precursor of today's eucaryotic nucleus. The study reveals that mammalian cells recognize, cluster, sort and keep extrachromosomal DNA -- like transfected plasmid DNA and endogenous circular DNAs originating from telomeres of the chromosome -- away from chromosomal DNA. That suggests that there is a cell autonomous genome defense system.
Published Sustainable protection of rapidly subsiding coastlines with mangroves
(via sciencedaily.com)
Original source 
Along the Asian coast lines there are many areas where rural communities experience alarming rates of sea level rises due to land subsidence up to 10 cm per year. This causes tremendous challenges on how to live there and protect these coasts. Scientists have now investigated the potential and limitation of mangrove restoration as a cost-effective and sustainable solution for coastal protection in rapidly subsiding areas.
Published Researchers studied thousands of fertility attempts hoping to improve IVF
(via sciencedaily.com)
Original source 
By genetically testing nearly one thousand embryos, scientists have provided the most detailed analysis of embryo fate following human in vitro fertilization.
Published Researchers propose a unified, scalable framework to measure agricultural greenhouse gas emissions
(via sciencedaily.com)
Original source 
Increased government investment in climate change mitigation is prompting agricultural sectors to find reliable methods for measuring their contribution to climate change. With that in mind, scientists have proposed a supercomputing solution to help measure individual farm field-level greenhouse gas emissions.
Published Dense measurement network links air pollution and common agricultural practice
(via sciencedaily.com)
Original source 
The annual burning of crop residue in India causes widespread air pollution, particularly in the northwestern regions. A group of international researchers has used low-cost yet reliable instruments to gauge the effects of air pollution in these areas.
Published Groundbreaking mathematical proof: New insights into typhoon dynamics unveiled
(via sciencedaily.com)
Original source 
A research team has provided irrefutable proof that certain spherical vortices exist in a stable state.
Published Small but mighty new gene editor
(via sciencedaily.com)
Original source 
A new CRISPR-based gene-editing tool has been developed which could lead to better treatments for patients with genetic disorders. The tool is an enzyme, AsCas12f, which has been modified to offer the same effectiveness but at one-third the size of the Cas9 enzyme commonly used for gene editing. The compact size means that more of it can be packed into carrier viruses and delivered into living cells, making it more efficient.
Published Ancient plant wax reveals how global warming affects methane in Arctic lakes
(via sciencedaily.com)
Original source 
In a new study, researchers examined the waxy coatings of leaves preserved as organic molecules within sediment from the early-to-middle Holocene, a period of intense warming that occurred due to slow changes in Earth's orbit 11,700 to 4,200 years ago. They found that warming potentially could lead to a previously under-appreciated flux in methane emissions from lakes.
Published Gut inflammation caused by substance secreted by microbe
(via sciencedaily.com)
Original source 
A rare subtype of the world's most common parasite, Blastocystis, has been found to produce a unique by-product of its metabolism, which can cause gut inflammation under normal gut conditions.
Published Timing plant evolution with a fast-ticking epigenetic clock
(via sciencedaily.com)
Original source 
Recent discoveries in the field of epigenetics, the study of inheritance of traits that occur without changing the DNA sequence, have shown that chronological age in mammals correlates with epigenetic changes that accumulate during the lifetime of an individual. In humans, this observation has led to the development of epigenetic clocks, which are now extensively used as biomarkers of aging. While these clocks work accurately from birth until death, they are set back to zero in each new generation. Now, an international team shows that epigenetic clocks not only exist in plants, but that these clocks keep ticking accurately over many generations.
Published A lethal parasite's secret weapon: Infecting non-immune cells
(via sciencedaily.com)
Original source 
The organisms that cause visceral leishmaniasis, a potentially deadly version of the parasitic disease that most often affects the skin to cause disfiguring disease, appear to have a secret weapon, new research suggests: They can infect non-immune cells and persist in those uncommon environments.
Published An advance in cryo-EM could be a significant boon for research on potential cancer therapies
(via sciencedaily.com)
Original source 
A technology called cryo-electron microscopy enables scientists to see the atomic structure of biological molecules in high resolution. But to date, it has been ineffective for imaging small molecules. A team of biochemists devised a solution that makes it possible to hold small protein molecules in place while they're being imaged, which will enable cryo-EM to produce much clearer images of such molecules. The advance is significant because small and medium-sized protein molecules are an area of focus in research on potential new drugs for cancer and other diseases.
Published Fish reveal cause of altered human facial development
(via sciencedaily.com)
Original source 
Some substances in medicines, household items and the environment are known to affect prenatal child development. Researchers tested the effects of five drugs (including caffeine and the blood thinner warfarin) on the growth of zebrafish embryos. They found that all five had the same effect, impairing the migration of bone-forming cells which resulted in the onset of facial malformation. Zebrafish embryos grow quickly, are transparent and develop outside of the parent's body, making them ideal for studying early development. A zebrafish-based system could be used to easily screen for potentially harmful substances, reducing animal testing on mammals and supporting parents-to-be when making choices for themselves and their baby.
