Dietary Fiber Helps Clump Material in Your Gut
Dietary Fiber Helps Clump Material in Your Gut
Food, microbes, and medicine all clump together as they move through our gut. Sticky molecules secreted into our intestines bind the gut particles in the same way that flour holds a ball of dough together. Now a new mice-based study from Caltech is showing that dietary fiber also plays a role in clumping.

Improving diagnosis of colorectal cancer
Current faecal blood tests for colorectal cancer have a sixty percent false positive rate. New funding from Cancer Research UK is helping scientists at Cardiff University to find better, safer tests . Inaccuracy of initial tests for colorectal cancer are putting patients at unnecessary risk, highlighting vital need for the development of precise and non-invasive testing.

The holy grail of nanowire production
The holy grail of nanowire production
EPFL researchers have found a way to control and standardize the production of nanowires on silicon surfaces. This discovery could make it possible to grow nanowires on electronic platforms, with potential applications including the integration of nanolasers into electronic chips and improved energy conversion in solar panels.

Researchers Develop Method To ID Diseases with Less Data
As artificial intelligence systems learn to better recognize and classify images, they are becoming highly reliable at diagnosing diseases, such as skin cancer, from medical images. But as good as they are at detecting patterns, AI won't be replacing your doctor any time soon. Even when used as a tool, image recognition systems still require an expert to label the data, and a lot of data at that: it needs images of both healthy patients and sick patients.

Making Green Cars Greener
CMU Researchers Examine Ways To Recycle Electric Vehicle Batteries The widespread implementation of electric vehicles will go a long way toward eliminating the greenhouse gas emissions of the transportation sector. But these emissions don't just come from the tailpipe. There's another major culprit of greenhouse gases, one that the electric vehicle industry might need some help from policymakers to avoid: battery recycling.

Mega-experiment shows species interactions stronger towards tropics and lowlands
One of the largest field experiments ever conducted is providing the best evidence yet in support of a key Darwinian theory-that interactions between species are stronger toward the tropics and lower elevations An international research team led by a McGill University researcher used a simple experiment that mimics how plants and animals interact with each other-leaving seeds out for 24 hours to see how many get eaten.

Potential link between vitamin D deficiency and loss of brain plasticity
Potential link between vitamin D deficiency and loss of brain plasticity
University of Queensland research may explain why vitamin D is vital for brain health, and how deficiency leads to disorders including depression and schizophrenia. Associate Professor Thomas Burne at UQ's Queensland Brain Institute led the studies, which provide the groundwork for research into better prevention and treatments.

UCLA faculty voice: Adolescents have a fundamental need to contribute
Andrew Fuligni is a professor of psychiatry and psychology at UCLA. This article appeared in The Conversation. No longer children but not yet adults, adolescents need opportunities to learn and prepare for their entrance into the broader society. But, as schooling increasingly extends the adolescent period and teenagers get dismissed as supposedly selfish and irresponsible, has society forgotten an important developmental need of our youth?

"Origami" diagnostic device offers affordable malaria diagnoses
Simple folded sheets of waxed paper could help bring affordable, reliable field tests for diseases such as malaria to remote parts of the developing world, scientists say. In a new paper published in the journal Proceedings of the National Academy of Sciences, researchers from universities in Scotland and China, working together with the Ministry of Health in Uganda, describe for the first time how origami-style folded paper, prepared with a printer and a hot plate, has helped detect malaria with 98% sensitivity in infected participants from two primary schools in Uganda.

Seeing the unseeable
Researchers at Cardiff University have used x-ray crystallography and computer simulation to get a closer look at how viruses bind cells and cause infection. The new insight could help in the development of drugs and therapies for infections and further advance the exploitation of viruses for medical treatments.

More primary care physicians leads to longer life spans
Life expectancy grows when there are more primary care physicians in the field, yet their numbers are shrinking as medical students saddled with debt turn to more lucrative fields, according to a study led by researchers at Stanford and Harvard. New research shows us just how important primary care physicians are in prolonging our lives.

Astronomers detect hundreds of thousands of previously unknown galaxies
A major new radio sky survey has revealed hundreds of thousands of previously undetected galaxies, shedding new light on many research areas including the physics of black holes and how clusters of galaxies evolve. An international team of more than 200 astronomers from 18 countries, including researchers from the University of Oxford, has published the first phase of the survey at unprecedented sensitivity using the Low Frequency Array (LOFAR) telescope.

Is lab-grown meat really better for the environment?
Growing meat in the laboratory may do more damage to the climate in the long run than meat from cattle, according to new research. In a first-of-its-kind study from the LEAP (Livestock, Environment and People) programme at the Oxford Martin School, the climate-change impact of several production methods for lab-grown and farmed beef was assessed accounting for the differing greenhouse gases produced.

World's first gene therapy operation for common cause of sight loss carried out
World’s first gene therapy operation for common cause of sight loss carried out
Researchers in Oxford have carried out the world's first gene therapy operation to tackle the root cause of age-related macular degeneration (AMD), the UK's most common cause of sight loss. The procedure was carried out at the John Radcliffe Hospital by Professor Robert MacLaren, Professor of Ophthalmology at the University of Oxford, with the support of the NIHR Oxford Biomedical Research Centre in a clinical trial sponsored by Gyroscope Therapeutics, a UK-based company developing genetically-defined therapies for the treatment of eye diseases.

Extinguishing fear memories relies on an unusual change to DNA
Researchers at The University of Queensland have discovered a DNA modification that enhances our ability to extinguish fear. The findings, published , could help guide the development of new treatments for fear-related anxiety disorders. Professor Timothy Bredy of UQ's Queensland Brain Institute (QBI) said while fear is an important survival mechanism which uses cues in the environment to prompt certain responses, so too is the ability to inhibit fear when it's no longer needed.

Rosetta's comet sculpted by stress
Rosetta’s comet sculpted by stress
Feeling stressed? You're not alone. ESA's Rosetta mission has revealed that geological stress arising from the shape of Comet 67P/Churyumov-Gerasimenko has been a key process in sculpting the comet's surface and interior following its formation. Small, icy comets with two distinct lobes seem to be commonplace in the Solar System, with one possible mode of formation a slow collision of two primordial objects in the early stages of formation some 4.5 billion years ago.

Climate change makes summer weather stormier yet more stagnant
Study finds rising temperatures feed more energy to thunderstorms, less to general circulation. Climate change is shifting the energy in the atmosphere that fuels summertime weather, which may lead to stronger thunderstorms and more stagnant conditions for midlatitude regions of the Northern Hemisphere, including North America, Europe, and Asia, a new MIT study finds.

Superconduction: Why does it have to be so cold?
Superconduction: Why does it have to be so cold?
Currently, there is no precise computation method to describe superconducting materials. TU Wien has now made a major advance towards achieving this goal and, at the same time, has furthered an understanding of why conventional materials only become superconducting at around -200°C Why does it always have to be so cold? We now know of a whole range of materials that ' under certain conditions ' conduct electrical current entirely without resistance.
