INDIANAPOLIS -- Artificial intelligence (AI)-driven healthcare has the potential to transform medical decision-making and treatment, but these algorithms must be thoroughly tested and continuously monitored to avoid unintended consequences to patients.
ROCHESTER, Minn. -- Patients diagnosed with post-COVID-19 syndrome, also known as "PCS," "COVID-19 long-haul syndrome" and "Post-Acute Sequelae of SARS COV-2," experience symptoms such as mood disorders, fatigue and perceived cognitive impairment that can negatively affect returning to work and resuming normal activities, according to a Mayo Clinic study published in Mayo Clinic Proceedings.
An international team of researchers at Great Ormond Street Hospital (GOSH), and University of California, Los Angeles (UCLA) have developed a gene therapy that successfully treated 48 out of 50 children with a form of severe combined immunodeficiency that leaves them without an immune system.
Saw-toothed grain beetles live in a symbiotic association with bacteria. Their bacterial partners provide important building blocks for the formation of the insect's exoskeleton, which protects the beetles from their enemies as well as from desiccation. In a new study, a team of scientists from the Johannes Gutenberg University in Mainz, the Max Planck Institute for Chemical Ecology in Jena, and the National Institute of Advanced Industrial Science and Technology in Japan demonstrates that glyphosate inhibits the symbiotic bacteria of the grain beetle.
Inks containing metal nanoparticles are among the most commonly-used conductive materials for printed electronics. Ink-jetting layers of MNP materials allows for unpreceded design flexibility, rapid processing and 3D printing of functional electronic devices such as sensors, solar panels, LED displays, transistors and smart textiles.
Researchers at the University of Bristol have discovered how microbes responsible for human African sleeping sickness produce sex cells.
In these single-celled parasites, known as trypanosomes, each reproductive cell splits off in turn from the parental germline cell, which is responsible for passing on genes. Conventional germline cells divide twice to produce all four sex cells - or gametes - simultaneously. In humans four sperms are produced from a single germline cell. So, these strange parasite cells are doing their own thing rather than sticking to the biology rulebook.
Every high-school physics student learns that sound and light travel at very different speeds. If the brain did not account for this difference, it would be much harder for us to tell where sounds came from, and how they are related to what we see.
Instead, the brain allows us to make better sense of our world by playing tricks, so that a visual and a sound created at the same time are perceived as synchronous, even though they reach the brain and are processed by neural circuits at different speeds.
Like many around the world, the lab of Professor Mriganka Sur in The Picower Institute for Learning and Memory at MIT has embraced the young technology of cerebral organoids, or "minibrains," for studying human brain development in health and disease. By making a surprising finding about a common practice in the process of growing the complex tissue cultures, the lab has produced both new guidance that can make the technology better, and also new insight into the important roles a prevalent enzyme takes in natural brain development.
Duluth, Minnesota - A new paper in the May issue of Nature Communications demonstrates why keeping local lakes and other waterbodies clean produces cost-effective benefits locally and globally.

One of the most basic structural aspects of relativistic spacetime is the description of how time and distances are altered by motion. The theory of special relativity describes a spacetime framework for linear constant motion in which time dilates and lengths contract in response to motion. This framework is described by the Lorentz transformation, which encompasses mathematical formulas that describe how time and distance are altered between moving reference frames.
A new study from the University of Portsmouth calls for further government oversight to curb potential illegal activity through these zones.
This study demonstrates the attractive trading advantages offered by freeports to enable enterprise and innovation. Eight new freeports in England are due to enter operation in late 2021, which are hoped to drive investment, economic opportunities and growth to those regions.
In recent decades, Spain has undergone rapid social changes in terms of gender equality, despite, as a result of the Franco dictatorship, starting from a more backward position than most European countries. This process is hampered by the economic downturn that began in 2008, underlining the importance of the economic context in the development of gender inequality levels. Little attention has been paid in academia to how this gender revolution is associated with factors related to individual wellbeing.
It was commonly assumed that wildlife products are exported from low-income countries to meet the demand of consumers in wealthy economies, and therefore, a widening wealth gap may drive up the volume of global trade and endanger wildlife.
YouTube channels run by zoos focus on entertainment over education, according to a new study.
The videos also focus disproportionately on mammals, rather than reflecting the diversity of zoos' animals.
Conservation was the focus of just 3% of zoo videos in the study - but it found that conservation content in videos is gradually increasing.
The study evaluated the most recent and most-viewed videos, so the findings partly reflect the public's preference for certain species and content.
