Repairing and reusing plastics and delivering cancer drugs more effectively are only two of many of the potential applications a new 3D/4D printing technology might have, thanks to the pioneering work of a research collaboration between UNSW Sydney and The University of Auckland.

The researchers have revealed the successful merging of 3D/4D printing and photo-controlled/living polymerisation - a chemical process to create polymers - in a paper published in Angewandte Chemie International Edition on Friday.

University of Adelaide wine researchers say their latest discovery may one day lead to winemakers being able to manipulate the acidity of wines without the costly addition of tartaric acid.

The team of researchers has uncovered a key step in the synthesis of natural tartaric acid in wine grapes - identifying and determining the structure of an enzyme that helps make tartaric acid in the grapes.

WASHINGTON, D.C., November 19, 2019 -- Blood clots have long been implicated in heart attacks and strokes, together accounting for almost half of deaths annually in the United States. While the role of one key protein in the process, called von Willebrand factor, has been established, a reliable model for predicting how vWF collects in blood vessels remains elusive.

WASHINGTON, D.C., November 19, 2019 -- Multiple myeloma is a type of blood cancer in which malignant plasma cells, a type of white blood cell, accumulate in the bone marrow. This leads to bone destruction and failure of the marrow, which in healthy individuals, produce all the body's red blood cells. The most recent data from the American Cancer Society estimates that almost 27,000 new cases of MM are diagnosed every year, and of these, over 11,000 patients died.

SAN FRANCISCO, CA November 19, 2019--For a person with Alzheimer's disease, there's no turning back the clock. By the time she begins to experience memory loss and other worrisome signs, cognitive decline has already set in. And decades of clinical trials have failed to produce treatments that could help her regain her memory.

Neurons that produce the neurotransmitter dopamine communicate with T cells to enhance allergic inflammation in the lungs of young mice but not older mice, researchers report November 19 in the journal Immunity. The findings potentially explain why asthma susceptibility is higher in children than in adults. By highlighting the important role of interactions between the nervous system and the immune system in childhood asthma, the results could lead to new strategies for treating the common chronic disease.

What The Study Did: This randomized clinical trial compared maternal blood loss with immediate umbilical cord clamping (within 15 seconds after birth) versus delayed clamping (60 seconds after birth) in 113 women who had a scheduled cesarean delivery at term of 37 weeks or more.

Some continuous glucose monitoring (CGM) alarm features and settings may achieve better blood sugar control for people with type 1 diabetes, according to a study published in the Journal of the Endocrine Society.

Scientists have peered inside the brain to show how taking DMT affects human consciousness by significantly altering the brain's electrical activity.

DMT (or dimethyltryptamine) is one of the main psychoactive constituents in ayahuasca, the psychedelic brew traditionally made from vines and leaves of the Amazon rainforest. The drink is typically prepared as part of a shamanic ceremony and associated with unusual and vivid visions or hallucinations.

HOUSTON -- Newly diagnosed prostate cancer patients have multiple standard-of-care treatment options available, but many are not fully informed of their choices. A study led by researchers at The University of Texas MD Anderson Cancer Center found men who seek treatment at a multidisciplinary (MultiD) prostate cancer clinic are more likely to be advised about treatment choices and to receive care that complies with evidence-based treatment guidelines.

Researchers from Istituto Italiano di Tecnologia (IIT) and University of Salento, both in Lecce, Italy, and Harvard Medical School in Boston have developed a new light-based method to capture and pinpoint the epicenter of neural activity in the brain.

Researchers at Tohoku University have, for the first time, successfully demonstrated a formation and current-induced motion of synthetic antiferromagnetic magnetic skyrmions. The established findings are expected to pave the way towards new functional information processing and storage technologies.

To investigate the problem of click interception, the research team led by Professor Wei Meng of the Department of Computer Science and Engineering, Faculty of Engineering, The Chinese University of Hong Kong (CUHK) developed a browser-based analysis framework - Observer, which is able to detect three different techniques for intercepting web user clicks. The research result has been published in USENIX Security Symposium 2019 (USENIX Security '19), one of the top academic conferences in computer security.

Researchers at the National Institute of Standards and Technology (NIST) have made one of the highest-performance cameras ever composed of sensors that count single photons, or particles of light.

With more than 1,000 sensors, or pixels, NIST's camera may be useful in future space-based telescopes searching for chemical signs of life on other planets, and in new instruments designed to search for the elusive "dark matter" believed to constitute most of the "stuff" in the universe.

Tracking the lateral position of single cells and particles plays an important role in evaluating the efficiency of microfluidic cell focusing, separation and sorting. Traditionally, the performance of microfluidic cell separation and sorting is evaluated either by analyzing the input and collected output samples requiring extra multiple steps of off-chip analysis or the use of expensive equipment (e.g., flow cytometry), or by detecting the lateral positions of cells using an expensive high-speed imaging setup with intricate image processing algorithms or laborious manual analysis.
