Vaping and edible use of marijuana growing among adolescent users
New University of Minnesota research shows fewer high school seniors in the U.S. are smoking marijuana. However, vaping and edible marijuana use are increasing. The study, published in JAMA Pediatrics , examined data collected from 12th grade students between 2015 and 2018 as part of the Monitoring the Future study - a National Institute on Drug Abuse survey that, among other items, measures drug and alcohol use among adolescent students.

In addition to high purchase costs and the still underdeveloped charging infrastructure, the limited range is one of the biggest obstacles to switching to electric vehicles. Industry and science are therefore working intensively on developing batteries with a higher energy density and making them suitable for series production.

On rare molecule could enhance cancer cell therapy
On rare molecule could enhance cancer cell therapy
Stanford chemists are developing new synthetic forms of a rare marine molecule that show promise for treating cancer and eradicating HIV. Stanford University chemist Paul Wender and his colleagues are working to improve treatments for cancer, HIV and Alzheimer's - and they are betting that a drab, weedy marine invertebrate is the means to achieving that end.

What social media can reveal about a community's well-being
What social media can reveal about a community’s well-being
Stanford scholar Johannes Eichstaedt has built an algorithm that can provide, in principle, a real-time indication of community well-being by analyzing social media posts. Social media can reveal more than just a single person's mood or frame of mind. It can capture the psychological states of an entire population, according to new research by Stanford scholar Johannes Eichstaedt.

Dirty carbon reveals a sophisticated side
Dirty carbon reveals a sophisticated side
Tar, the everyday material that seals seams in our roofs and driveways, has an unexpected and unappreciated complexity, according to an MIT research team: It might someday be useful as a raw material for a variety of high-tech devices including energy storage systems, thermally active coatings, and electronic sensors.

Long-term use of synthetic corticosteroid drugs increases adrenal gland inflammation
Synthetic corticosteroid drugs are widely prescribed to treat many inflammatory and autoimmune diseases but taking a high dose over a long period of time can cause adverse side effects. Patients undergoing prolonged corticosteroid treatment can also develop adrenal insufficiency, which in rare occasions can lead to adrenal gland failure.

Analyzes contamination in drug manufacturing plants
Analyzes contamination in drug manufacturing plants
Over the past few decades, there have been a handful of incidents in which manufacturing processes for making protein drugs became contaminated with viruses at manufacturing plants. These were all discovered before the drugs reached patients, but many of the incidents led to costly cleanups and in one instance a drug shortage.

New model of the GI tract could speed drug development
New model of the GI tract could speed drug development
Studies of drug absorption in the small intestine could help researchers identify medicines that can be taken orally. MIT engineers have devised a way to speed up the development of new drugs by rapidly testing how well they are absorbed in the small intestine. This approach could also be used to find new ways to improve the absorption of existing drugs so that they can be taken orally.

What COVID-19 antibody tests can tell us, and what they can’t

(UCSF photo by Susan Merrell) As the United States and much of the world move toward relaxing shelter-in-place restrictions to let people move about more freely, public health experts hope to rely on antibody tests to determine who has been infected with the COVID-19 virus and may be immune - at least temporarily - and who is still susceptible.

Bacteria that are persistently resistant to one antibiotic are 'primed' to become multidrug-resistant bugs
Bacteria that are persistently resistant to one antibiotic are ’primed’ to become multidrug-resistant bugs
Antibiotics save lives - but using them also helps antibiotic-resistant strains evolve and spread. Each year, antibiotic-resistant bacteria infect some 2.8 million people in the United States, killing more than 35,000, according to the Centers for Disease Control and Prevention. Infections by multidrug-resistant - or MDR - bacteria, which are resistant to two or more antibiotics, are particularly difficult to treat.

Currently, the corona pandemic is dominating the entire social life in Germany and in many other parts of the world. We are working flat out in order to better help the more than one hundred thousand seriously ill people in hospitals. One promising approach to extending current treatment methods is to use existing and approved drugs to combat the virus.

Containment measures avoid 200,000 hospitalizations in Italy
Containment measures avoid 200,000 hospitalizations in Italy
Researchers have modeled the effects of containment and social distancing measures implemented by the Italian government to prevent the spread of COVID-19. Their findings show that contagion transmission was reduced by 45% in March. The model will now be used to analyze possible future scenarios. Since the beginning of the COVID-19 pandemic, mobility restrictions and social distancing measures implemented by the Italian government have avoided at least 200,000 hospitalizations and, over time, reduced contagion transmission by 45%.

Rapid evolution in fish: genomic changes within a generation
Researchers from Basel have identified the genetic basis of rapid adaptation using a native fish species. They compared threespine stickleback fish from different habitats in the Lake Constance region. Their study reveals that changes in the genome can be observed within a single generation. The results were published Communications.

Superconductivity: It's Hydrogen's Fault
Superconductivity: It’s Hydrogen’s Fault
Nickel is supposed to herald a new age of superconductivity - but this is proving more difficult than expected. Scientists at TU Wien (Vienna) can now explain why. Last summer, a new age for high-temperature superconductivity was proclaimed - the nickel age. It was discovered that there are promising superconductors in a special class of materials, the so-called nickelates, which can conduct electric current without any resistance even at high temperatures.

New tool measures quality of life in people with dementia
University of Queensland researchers say a new tool to measure the quality of life of people with dementia will result in better targeted care for those living with the condition. The method assesses five key domains that contribute to quality of life - physical health, mood, memory, living situation and ability to do fun activities, and importantly, takes into account the views of people with dementia.

Why we adopt then abandon online safety practices
We try to follow experts' cybersecurity and privacy recommendations but quite often many of us do so halfway or we give up. There are too many steps. The repetitious procedures get cumbersome. The trade-off of reduced access to information in exchange for a vague sense of security doesn't seem worth it.

Microneedles made of silk-based material can target plant tissues for delivery of micronutrients, hormones, or genes. While the human world is reeling from one pandemic, there are several ongoing epidemics that affect crops and put global food production at risk. Oranges, olives, and bananas are already under threat in many areas due to diseases that affect plants' circulatory systems and that cannot be treated by applying pesticides.

Weekly COVID-19 testing in healthcare and care home staff may reduce spread
A new report looks at how different testing strategies could help control COVID-19. The World Health Organisation has called for increased molecular testing in response to the COVID-19 pandemic but different countries have taken very different approaches. “We find that testing is most useful when targeted at high-risk groups such as healthcare and care home staff.? Professor Nicholas Grassly Study author The new report investigates how effective alternative strategies could be for COVID-19 control, using a mathematical model.
