Modern hospitals and antibiotic treatment alone did not create all the antibiotic resistant strains of bacteria we see today. Instead, selection pressures from before widespread use of antibiotics influenced some of them to develop, new research has discovered.
Teachers who participated in a meditation-based teacher development program utilizing the Transcendental Meditation (TM) technique for four months, had significant improvements in emotional exhaustion (the leading factor in burnout), resilience, perceived stress, fatigue, and depression according to a new randomized controlled trial published today in Frontiers in Education.
In a new study by the Yale Department of Immunobiology and Yale Cancer Center, researchers report combined liver and growth factor humanization enhances human red blood cell production and survival in circulation the immunodeficient murine host. The discovery could help in the development of treatments of life-threatening blood disorders, such as myelodysplastic syndrome, and diseases afflicting red blood cells, including sickle cell disease and malaria. The study is published online today in the journal Science.
The idea of creating selectively porous materials has captured the attention of chemists for decades. Now, new research from Northwestern University shows that fungi may have been doing exactly this for millions of years.
When Nathan Gianneschi's lab set out to synthesize melanin that would mimic that which was formed by certain fungi known to inhabit unusual, hostile environments including spaceships, dishwashers and even Chernobyl, they did not initially expect the materials would prove highly porous-- a property that enables the material to store and capture molecules.
What The Study Did: Survey data were used to estimate changes in racial/ethnic disparities in rates of autism spectrum disorder among U.S. children and adolescents from 2014 through 2019.
Authors: Z. Kevin Lu, Ph.D., of the University of South Carolina in Columbia, is the corresponding author.

Researchers have developed a new quantum version of a 150-year-old thermodynamical thought experiment that could pave the way for the development of quantum heat engines.
Mathematicians from the University of Nottingham have applied new quantum theory to the Gibbs paradox and demonstrated a fundamental difference in the roles of information and control between classical and quantum thermodynamics. Their research has been published today in Nature Communications.
DUBLIN, Friday, 5 March 2021: RCSI researchers have discovered a new way to 'put the brakes' on excessive inflammation by regulating a type of white blood cell that is critical for our immune system.
The discovery has the potential to protect the body from unchecked damage caused by inflammatory diseases.
The paper, led by researchers at RCSI University of Medicine and Health Sciences, is published in Nature Communications.
Kanazawa, Japan - As the global population ages, the rate of dementia is increasing worldwide. Given that early detection is critical for treatment, effective ways to screen for dementia are a high research priority. Now, researchers from Japan have developed a new screening tool that can be administered in a matter of minutes.
Tsukuba, Japan - Heavy snowfall slows things down and makes it harder to get from point A to point B. But snow clouds have a silver lining--heavy snow may prevent serious road injuries and even save lives. How? By getting people off bicycles and switching to safer modes of transport.
MoS2 thin films of superposed alternating layers of molybdenum and sulfur atoms form a two-dimensional semiconducting surface. However, even a surprisingly low-intensity blue light pulse is enough to alter the properties of the surface and make it metallic. This has now been demonstrated by a team at BESSY II.
PULLMAN, Wash. - The ability to identify misinformation only benefits people who have some skepticism toward social media, according to a new study from Washington State University.
Oxidative dispersion has been widely used in the regeneration of sintered metal catalysts as well as the fabrication of single-atom catalysts.
The consensus on the oxidative dispersion process includes the formation of mobile metal oxide species from large metal particles and the capture of these species on a support surface. Nevertheless, the mechanism of oxidation-induced dispersion has yet to be confirmed via in situ electron microscopic and/or spectroscopic characterizations.
Female gannets travel further than male gannets to find fish for their chicks in some years but not others, new research shows.
Scientists tracked breeding gannets from Grassholm Island in Wales over 11 years with tiny GPS devices and by measuring isotopic signatures in their blood.
Male gannets flew an average of 220km to forage for their chicks, while females averaged 260km. Some birds travelled 1,000km on a single trip.
As odd as it sounds, many scientists have attempted to place extremely small diamonds inside living cells. Why? Because nanodiamonds are consistently bright and can give us unique knowledge about the inner life of cells over a long time. Now physics researchers at Lund University in Sweden have succeeded in injecting a large number of nanodiamonds directly to the cell interior.
Diamonds are not only sought after for their beauty, but also for their uniquely luminescent properties, at least among scientists. Unlike other fluorescent materials, they do not bleach.
BROOKLYN, New York, Wednesday, March 3, 2021 - Machine-learning (ML) systems are becoming pervasive not only in technologies affecting our day-to-day lives, but also in those observing them, including face expression recognition systems. Companies that make and use such widely deployed services rely on so-called privacy preservation tools that often use generative adversarial networks (GANs), typically produced by a third party to scrub images of individuals' identity. But how good are they?
