Can a smart app encourage HIV-self testing in Canada?
HIV self-testing strategies have been recommended by the World Health Organization (WHO) since 2016, as they empower people to find out HIV their status at their convenience. However, home-based testing kits have yet to be approved for sale in Canada.

’Chemputer’ promises app-controlled revolution for drug production
A radical new method of producing drug molecules, which uses downloadable blueprints to easily and reliably synthesise organic chemicals via a programmable ‘chemputer', could be set to democratise the pharmaceutical industry, scientists say. Chemputer In a new paper published online in the journal Science today (November 29) , researchers from the University of Glasgow present for the first time how synthesis of important drug molecules can be achieved in an affordable and modular chemical-robot system they call a chemputer.

New techniques to study deadly ovarian cancer
A particularly deadly form of ovarian cancer is so deadly in part because it is quick to develop resistance to the drugs used to treat it. Now, a team is using new materials and imaging techniques to better understand the disease. Facebook Twitter Email As if a cancer diagnosis isn't bad enough, women with one of the most common forms of ovarian cancer face a hard reality.

Study could lead to safer and cheaper 3D medical imaging
A new study led by ANU has discovered a promising way to significantly lower doses of X-rays that has the potential to revolutionise 3D medical imaging and make screening for early signs of disease much cheaper and safer. The research team, which involved the European Synchrotron Radiation Facility and Monash University, built upon an unconventional imaging approach known as "ghost imaging" to take 3D X-ray images of an object's interior that is opaque to visible light.

An opioid epidemic may be looming in Mexico - and the U.S. may be partly responsible
An opioid epidemic may be looming in Mexico - and the U.S. may be partly responsible
FINDINGS Opioid use in Mexico has been low, but national and international factors are converging and a threat of increased drug and addiction rates exists. Many of these factors may have originated in the U.S., making this a potential joint U.S.-Mexico epidemic. BACKGROUND Previously, various cultural and legislative factors had combined to keep opioid use low in Mexico.

New report calls for cultural shift in use of patient data by NHS and health technology companies
A radical culture change in the NHS and across the health data and medical technology community is needed to ensure the NHS can deliver the benefits of new health technologies, says a new report co-authored by a University of Oxford scientist. The report, published by the Academy of Medical Sciences , outlines principles that must be adopted by the NHS and medical industry so that digital information about patients can be used in smarter, more joined-up ways to revolutionise healthcare and support life-saving research.

Why culture is key to improving the "interpretive power" of psychology
In psychology, there often is a common demographic among research subjects. And among the researchers, themselves. And, in its own way, among research questions, processes and interpretations. A few years ago, a University of British Columbia research team  noticed this trend and came up with an acronym for this demographic: WEIRD, or Western, educated, industrialized, rich and democratic.

Cracking Open a Cold One with the Flies
Cracking Open a Cold One with the Flies
Crack open a beer outside and it is a safe bet that you will soon be defending it from a few unwelcome drinking buddies. Fruit flies have a knack for appearing whenever someone opens up a can of beer or a bottle of wine, but how do they do it? In a study spanning six years and thousands of experiments, Caltech scientists discovered that fruit flies are attracted to carbon dioxide (CO2), a gas associated with their favorite foods-and some of our favorite beverages.

Measuring cancer cell
Measuring cancer cell "fitness" reveals drug susceptibility
Together, cell growth rate and gene expression shed light on why some tumor cells survive treatment. By studying both the physical and genomic features of cancer cells, MIT researchers have come up with a new way to investigate why some cancer cells survive drug treatment while others succumb. Their new approach, which combines measurements of cell mass and growth rate with analysis of a cell's gene expression, could be used to reveal new drug targets that would make cancer treatment more effective.

With these nanoparticles, a simple urine test could diagnose bacterial pneumonia
Results could also indicate whether antibiotics have successfully treated the infection. Pneumonia, a respiratory disease that kills about 50,000 people in the United States every year, can be caused by many different microbes, including bacteria and viruses. Rapid detection of pneumonia is critical for effective treatment, especially in hospital-acquired cases which are often more severe.

A prosthetic arm that decodes phantom limb movements
A prosthetic arm that decodes phantom limb movements
Paris, 29 November 2018 About 75% of amputees exhibit mobility of their phantom limb. Using this information, in collaboration with physicians 1 , researchers from CNRS and Aix-Marseille University have developed a prototype capable of detecting these movements and activating a prosthetic arm. The prosthesis does not require any surgery and patients do not need training.

The polar regions communicate via postcards and text messages
A new study found two types of climatic connection between the North Atlantic and Antarctica. One is a rapid atmospheric channel and the other a much slower connection through the ocean. During the last glacial period, these links resulted in abrupt climatic changes - and could so again in future. In a study just published in the journal "Nature", an international team of researchers describes how an ocean current repeatedly strengthening and weakening again 60,000 to 12,000 years ago led to an extremely sudden change in the climate.

Understanding Down syndrome opens door to Alzheimer's prevention trials
Clinical trials for preventing Alzheimer's disease in people with Down syndrome may soon be possible thanks to new research from King's College London. The researchers found changes in memory and attention are the earliest signs of Alzheimer's in Down syndrome, and these changes start in the early 40s.

Arteries harvested from forearms are a safe heart bypass option - research
Australian researchers have shown that forearm arteries are more effective in coronary bypass surgery than the commonly used leg vein, in a finding that could improve the prognosis for many heart patients. For more than 20 years Royal Melbourne Hospital and University of Melbourne Professor Alistair Royse and his colleagues have used one of the two arteries in our forearms, the radial artery, which has proven more durable than using veins to bypass blocked arteries near the heart.

What happens when materials take tiny hits
High-speed camera shows incoming particles cause damage by briefly melting surfaces as they strike. When tiny particles strike a metal surface at high speed - for example, as coatings being sprayed or as micrometeorites pummeling a space station - the moment of impact happens so fast that the details of process haven't been clearly understood, until now.

Queensland deforestation policy failing to meet expectations
Australia has some of the highest rates of private land deforestation in the world, despite policies designed to prevent the practice. University of Queensland researchers have conducted what they believe to be the first robust analysis of a policy's ability to reduce deforestation of remnant trees in Queensland, amid debate about policy effectiveness and the significant costs to farmers and graziers.
