New research shows that tomato juice can kill Salmonella Typhi and other bacteria that can harm people's digestive and urinary tract health.
Our built environment is aging and failing faster than we can maintain it. Recent building collapses and structural failures of roads and bridges are indicators of a problem that's likely to get worse, according to experts, because it's just not possible to inspect every crack, creak and crumble to parse dangerous signs of failure from normal wear and tear. In hopes of playing catch-up, researchers are trying to give robotic assistants the tools to help inspectors with the job.
A new way of creating color uses the scattering of light of specific wavelengths around tiny, almost perfectly round silicon crystals. This development enables non-fading structural colors that do not depend on the viewing angle and can be printed. The material has a low environmental and biological impact and can be applied extremely thinly, promising significant weight improvements over conventional paints.
Biological systems can behave as siblings in several ways, including by borrowing something and never giving it back. That appears to be what the human immune system did with a protein that now helps bind and regulate the subunits that make up antibodies, according to a multi-institute research collaboration. They found that, before the immune system evolutionarily co-opted it, the protein originally belonged to gene family responsible for directing cells to move to the right location at the right time to address specific functional needs.
Researchers have observed rapid and distinct immune system changes in a small study of people who switched to a vegan or a ketogenic (also called keto) diet. Scientists closely monitored various biological responses of people sequentially eating vegan and keto diets for two weeks, in random order. They found that the vegan diet prompted responses linked to innate immunity -- the body's non-specific first line of defense against pathogens -- while the keto diet prompted responses associated with adaptive immunity -- pathogen-specific immunity built through exposures in daily life and vaccination. Metabolic changes and shifts in the participants' microbiomes -- communities of bacteria living in the gut -- were also observed.
The composition of microbiota found in the gut influences how susceptible mice are to respiratory virus infections and the severity of these infections.
A new study may change the way clinicians and scientists understand, diagnose and treat placenta accreta spectrum disorder, a serious condition in which the placenta fails to separate from the uterus at birth, jeopardizing the life and health of both mother and baby.
Scientists said that on the current pathway, food systems alone will push global warming above the Paris Deal’s more ambitious threshold of 1.5 degrees Celsius since preindustrial times
Black holes are so dense, and their gravitational pulls so strong, that their cores are permanently shrouded from the universe
Ingenuity ultimately buzzed over the Martian terrain 14 times farther than originally planned, logging more than two hours, eight minutes of flight time and covering a distance of 17 km through all 72 flights
The closest of the 19 galaxies is called NGC5068, about 15 million light years from Earth, and the most distant of them is NGC1365, about 60 million light years from Earth
The concept of the multiverse may become grounded some day in the tenets of physics after we find a way to test the theories that predict it
The Japan Aerospace Exploration Agency said it successfully established communication with the probe, and the craft has resumed its mission, taking pictures of the Moon’s surface and transmitting them to the Earth.
The James Webb Space Telescope observed 19 nearby face-on spiral galaxies in near- and mid-infrared light as part of its contributions to the Physics at High Angular resolution in Nearby GalaxieS (PHANGS) program.
Scientists have combined machine learning with information on blood metabolites to develop a new early diagnostic test that detects ovarian cancer with 93 percent accuracy.
New research reviewed publicly available information for 99 different organizations that coordinate large-scale tree-planting programs around the globe to see if these organizations seemed to be applying best practices for successful reforestation.
A startling number of people conceal an infectious illness to avoid missing work, travel, or social events, new research suggests.
Nerve cells in the brain demand an enormous amount of energy to survive and maintain their connections for communicating with other nerve cells. In Alzheimer's disease, the ability to make energy is compromised, and the connections between nerve cells (called synapses) eventually come apart and wither, causing new memories to fade and fail. A research team has now restored neuron-to-neuron connections in human cells.
Scientists have discovered a first-of-its-kind material, a 3D crystalline metal in which quantum correlations and the geometry of the crystal structure combine to frustrate the movement of electrons and lock them in place.
