Treatment for canine ocular condition using turmeric

Researchers have produced a therapeutic derived from turmeric, a spice long-praised for its natural anti-inflammatory properties, that shows promise in decreasing ocular inflammation in dogs suffering from uveitis, an inflammation of the eye that leads to pain and reduced vision.

To make a better sensor, just add noise

Adding noise to enhance a weak signal is a sensing phenomenon common in the animal world but unusual in manmade sensors. Now researchers have added a small amount of background noise to enhance very weak signals in a light source too dim to sense.

Wool-like material can remember and change shape

Researchers have developed a biocompatible material that can be 3D printed into any shape and pre-programmed with reversible shape memory. The material is made using keratin, a fibrous protein found in hair, nails and shells, extracted from leftover Agora wool used in textile manufacturing. It could be used in anything from self-fitting bras to actuating textiles for medical therapeutics and could...

Researchers redesign the face mask to improve comfort and protection

Imagine a reusable face mask that protects wearers and those around them from SARS-CoV-2, is comfortable enough to wear all day, and stays in place without frequent adjustment. Based on decades of experience with filtration and textile materials, researchers have designed a new mask intended to do just that -- and are providing the plans so individuals and manufacturers can make it.

Helping teens with type 1 diabetes improve diabetes control with MyDiaText

Adolescence is a difficult period of development, made more complex for those with Type 1 diabetes mellitus (T1DM). The challenges of managing multiple doses of daily insulin administration, blood glucose monitoring, dietary and exercise requirements, can make self-care difficult and complicate outcomes. Adolescents with T1DM often have poorer diabetes outcomes than others, indicating that glucose...

Peculiar planetary system architecture around three Orion stars explained

In our Solar System, the eight planets and many other minor objects orbit in a flat plane around the Sun; but in some distant systems, planets orbit on an incline -- sometimes a very steep one. New work could explain the architecture of multi-star systems in which planets are separated by wide gaps and do not orbit on the same plane as their host star's equatorial center.

Who should get the COVID-19 vaccine first?

Nineteen global health experts from around the world have proposed a new, three-phase plan for vaccine distribution -- called the Fair Priority Model -- which aims to reduce premature deaths and other irreversible health consequences from COVID-19.

Diabetes-in-a-dish model uncovers new insights into the cause of type 2 diabetes

Researchers have developed a novel 'disease-in-a-dish' model to study the basic molecular factors that lead to the development of type 2 diabetes, uncovering the potential existence of major signaling defects both inside and outside of the classical insulin signaling cascade, and providing new perspectives on the mechanisms behind insulin resistance in type 2 diabetes and possibly opportunities...

Novel insights of how prostate cancer causes secondary tumors

An increased awareness on a molecular level of what mechanisms prostate cancer cells use to become mobile and start spreading may in the long run provide new opportunities for treatment of aggressive prostate cancer. This according to a new study by researchers at Umeå University, Sweden, in collaboration with researchers in Uppsala and Tokyo.

How we sleep today may forecast when Alzheimer's disease begins

Neuroscientists have found a way to estimate, with some degree of accuracy, a time frame for when Alzheimer's is most likely to strike in a person's lifetime, based on their baseline sleep patterns. Their findings suggest one defense against this virulent form of dementia -- for which no treatment currently exists -- is deep, restorative sleep, and plenty of it.

How to capture images of cells at work inside our lungs

Scientists have discovered how to capture 'live' images of immune cells inside the lungs. The group is the first in the world to find a way to record, in real time, how the immune system battles bacteria impacting the alveoli, or air sacs, in the lungs of mice. The discovery has already provided new insights about the immune systems' cleaners, called alveolar macrophages.

Is consciousness continuous or discrete? Maybe it's both, argue researchers

Two major theories have fueled a now 1,500 year-long debate started by Saint Augustine: Is consciousness continuous, where we are conscious at each single point in time, or is it discrete, where we are conscious only at certain moments of time? Psychophysicists answer this centuries-old question with a new model, one that combines both continuous moments and discrete points of time.

Attacking tumors from the inside

A new technology that allows researchers to peer inside malignant tumors shows that two experimental drugs can normalize aberrant blood vessels, oxygenation, and other aspects of the tumor microenvironment in non-small cell lung cancer (NSCLC), helping to suppress the tumor's growth and spread, researchers report.

Comprehensive look at US fuel economy standards show big savings on fuel and emissions

A new study finds that over their 40-year history, fuel economy standards in the United States have helped reduce reliance on foreign oil producers, saved $5 trillion in fuel costs and prevented 14 billion metric tons of carbon from being released into the atmosphere. The standards (known as CAFE standards), first enacted to reduce foreign oil dependence, were cost-effective, fair, durable and...

Autonomous robot plays with NanoLEGO

Atoms and molecules behave in a completely different way to macroscopic objects and each brick requires its own 'instruction manual'. Scientists have now developed an artificial intelligence system that autonomously learns how to grip and move individual molecules using a scanning tunneling microscope.

When doing good boosts health, well-being

Performing acts of kindness and helping other people can be good for people's health and well-being, according to new research. But not all good-hearted behavior is equally beneficial to the giver. The strength of the link depends on many factors, including the type of kindness, the definition of well-being, and the giver's age, gender and other demographic factors.

Tiny biological package gets drug right to the 'heart' of transplant rejection

For patients who receive a heart transplant in the near future, the old adage, 'Good things come in small packages,' may become words to live by. Researchers have demonstrated in mice that they can easily deliver a promising anti-rejection drug directly to the area surrounding a grafted heart by packaging it within a tiny three-dimensional, protein gel cocoon known as a hydrogel.

Natural pest control saving billions

Biological control of insect pests - where 'natural enemies' keep pests at bay - is saving farmers in Asia and the Pacific billions of dollars, according to new research. Biological control involved the careful release of an exotic natural enemy from a pest's native habitat.

Children can have COVID-19 antibodies and virus in their system simultaneously

With many questions remaining around how children spread COVID-19, researchers set out to improve the understanding of how long it takes pediatric patients with the virus to clear it from their systems, and at what point they start to make antibodies that work against the coronavirus. The study finds that the virus and antibodies can coexist in young patients.
