Scientists have developed a method that improves the accuracy of DNA sequencing up to a thousand times. The method, which uses nanopores to read individual nucleotides, paves the way for better -- and cheaper -- DNA sequencing.
Scientists have deciphered the genetic code that instructs proteins to either self-assemble or disassemble in response to environmental stimuli, such as changes in temperature, salinity or acidity. The discovery provides a new platform for drug delivery systems and an entirely different view of cellular functions.
If Canada's new government decides to legalize cannabis, public health must be the top priority to prevent commercialization and promotion by 'Big Cannabis' and subsequent possible harms, argues an analysis.
When it comes to climate change, it's rare to get any good news. But a researcher who's reported evidence, after more than two decades of study, has some: the loss of sea ice over Antarctic waters in some areas has led to the increased growth of creatures living on the seafloor. Those underwater assemblages are acting as an important and unexpected carbon sink.
With careful management, selectively logged tropical Amazonian forests can recover their carbon stocks within a cutting cycle of 20 to 30 years, according to researchers. The findings show that sustainably logged tropical forests continue to play a key role in global carbon sequestration, with important implications for global climate.
Imagine a 'smart pill' that can sense problems in your intestines and actively release the appropriate drugs. We have the biological understanding to create such a device, but we're still searching for electronic materials (like batteries and circuits) that pose no risk if they get stuck in our bodies. Now researchers present a vision for creating safe, consumable electronics, such as those powered by the charged ions within our digestive tracts.
For adults, memories tend to fade with time. But a new study has shown that there are circumstances under which the opposite is true for small children: they can remember a piece of information better days later than they can on the day they first learned it.
The assumption that rising unemployment, leads to rising crime in the UK, is being challenged by new research. The study has found that the relationship between the economy and crime rates has varied over time. Specifically, researchers discovered that the association between unemployment and property crime - which was strong in the 1970s and 1980s - weakened after 1995 and became non-existent by 2005. These findings help to shed light on why the recorded crime rate did not rise following the 2007-2008 financial crisis.
Men are surprisingly positive and open to the concept of having cancer-detecting biosensors implanted within their bodies – effectively making them cyborgs -- new research suggests.
New analysis of the effects of melting permafrost in the Arctic points to $43 trillion in extra economic damage by the end of the next century, on top of the more than the $300 trillion economic damage already predicted.
Light, sound, and now, heat -- just as optical invisibility cloaks can bend and diffract light to shield an object from sight, and specially fabricated acoustic metamaterials can hide an object from sound waves, a recently developed thermal cloak can render an object thermally invisible by actively redirecting incident heat.
Findings of low-oxygen tolerance among blue crabs contradict earlier studies, thus helping to explain what had been somewhat of an ecological mystery. The researchers undertook the study in light of concerns about decreasing levels of oxygen in coastal waters worldwide, and how the growing prevalence of low-oxygen "dead zones" might affect populations and management of blue crabs and other coastal marine life.
Individuals make more conservative choices when the decisions they make affect other people, according to a new study. The study also found that conformism, or changing one's behavior to match the responses of others, also had an effect on risk taking. Observing the choice of another leads both individual and social decisions toward whatever the other person's expressed risk preference is.
Using components made from smart shape-memory materials with slightly different responses to heat, researchers have demonstrated a four-dimensional printing technology that allowed creation of complex self-folding structures.
A recent study is the first to examine and identify a link between kidney stones in children and thickened or hardened arteries -- precursors to a wide variety of cardiovascular diseases. Understanding the connection between kidney stones and cardiovascular risk factors in children may help physicians and parents implement prevention measures to reduce future risk of stroke, heart attack or other forms of vascular disease for affected children.
The efforts of the international community for the past ten years in the fight against malaria have reduced the number of disease-related deaths. The in vitro examination of a strain of parasites solely exposed to artemisinin (the base compound for standard therapy) demonstrates the development of a widespread resistance to most other anti-malarial drugs.
Much of the nation's energy policy is premised on the assumption that clean renewable sources like wind and solar will require huge quantities of storage before they can make a significant dent in the greenhouse gas emissions from electricity generation. A new study pokes holes in that conventional wisdom. The analysis finds that the supply of wind and solar power could be increased tenfold without additional storage.
Young people who are not in education, employment or training are committed to working but vulnerable to experiencing mental health problems, according to a new study.
New research finds that young black men and teens who are most likely to be victims or perpetrators of violence are also those who feel that they have the least power to effect social change -- highlighting the importance of ensuring that young black men do not feel alienated by society and social programs.
Protein flexibility is essential for enzymatic turnover, signalling regulation and protein-protein interactions. Multiple crystal structures are routinely compared to identify these motions and to derive hypotheses about the role of correlated motions in executing protein function. However, if only a single crystal form is available, evidence of concerted motion must be extracted from the spread in the electron density. Diffuse X-ray scattering can help by reporting on correlated atomic displacements.
