Chaos gives the quantum world a temperature

A single particle has no temperature. It has a certain energy or a certain speed — but it is not possible to translate that into a temperature. Only when dealing with random velocity distributions of many particles, a well-defined temperature emerges. How can the laws of thermodynamics arise from the…

Using machine learning to improve the toxicity assessment of chemicals

Researchers of the University of Amsterdam, together with colleagues at the University of Queensland and the Norwegian Institute for Water Research, have developed a strategy for assessing the toxicity of chemicals using machine learning. They present their approach in an article in Environmental Science & Technology for the special issue…

Olfactory viral inflammation associated with accelerated onset of Alzheimer’s disease: CU Anschutz researchers suspect it disrupts the olfactory tract, impacting the hippocampus which controls memory and learning

Viruses can inflame and disrupt connections between the olfactory system, which governs the sense of smell, and the part of the brain associated with memory and learning, possibly accelerating the onset of Alzheimer’s disease, according to a new study from researchers at the University of Colorado Anschutz Medical Campus. The…

Preoperative immunotherapy for mesothelioma shows favorable outcomes

In a study published recently in the journal Clinical Cancer Research, researchers at Baylor College of Medicine found that treating patients who have resectable malignant pleural mesothelioma, meaning that their tumor can be removed with surgery, with immunotherapy ahead of surgery resulted in favorable clinical outcomes. The study lays the…

Precision insights can be found in wastewater

Research from the lab of Fangqiong Ling at Washington University in St. Louis showed earlier this year that the amount of SARS-CoV-2 in a wastewater system was correlated with the burden of disease — COVID-19 — in the region it served. But before that work could be done, Ling needed…

Patients with treatment resistant depression at higher risk of early death

Patients with treatment resistant depression have a 23 per cent higher risk of death than other depressed patients. They also have twice as much outpatient care and spend three times the number of days in inpatient care. These are findings of a new study published in JAMA Psychiatry by researchers…

UK government eyes ban on single-use plastic plates and cutlery | CNN

CNN  —  Single-use plastic cutlery, plates and other items are set to be banned by the UK government and replaced by biodegradable items as it seeks to tackle the country’s – and the world’s – growing plastic waste problem. The UK has already banned some single-use plastic items, including straws,…

Shedding light on photosynthesis at sea

Plants that live on land, such as spinach, grow by using sunlight to perform photosynthesis. How, then, do algae photosynthesize in the deep sea, an environment where only a little light reaches them? Land plants mainly absorb red and blue light from the sun and use it for photosynthesis. However,…

How sick leave pay in Italy compares to other countries in Europe

Your right to paid time off when you’re unwell varies considerably from country to country. From how many days you can take to whether you’ll get your full salary and when you need a doctor’s note, here’s how the rules in Italy compare to elsewhere in Europe. Source link

Second journalist dies during Qatar World Cup 

Workers walk between safety barricades at Al-Wakrah Stadium that is under construction for the 2022 World Cup in Doha, Qatar on May 4, 2015. (Maya Alleruzzo/AP) World Cup chief Hassan Al-Thawadi said that between 400 and 500 migrant workers have died as a result of work done on projects connected to the tournament…

Quantum dots at room temp, using lab-designed protein

Nature uses 20 canonical amino acids as building blocks to make proteins, combining their sequences to create complex molecules that perform biological functions. But what happens with the sequences not selected by nature? And what possibilities lie in constructing entirely new sequences to make novel, or de novo, proteins bearing…

Changes in Earth’s orbit may have triggered ancient warming event

Changes in Earth’s orbit that favored hotter conditions may have helped trigger a rapid global warming event 56 million years ago that is considered an analogue for modern climate change, according to an international team of scientists. “The Paleocene-Eocene Thermal Maximum is the closest thing we have in the geologic…

Particles of light may create fluid flow, data-theory comparison suggests

A new computational analysis by theorists at the U.S. Department of Energy’s Brookhaven National Laboratory and Wayne State University supports the idea that photons (a.k.a. particles of light) colliding with heavy ions can create a fluid of “strongly interacting” particles. In a paper just published in Physical Review Letters, they…

Mapping E. coli to overcome antibiotic resistance

Antibiotic resistance, when infection-causing bacteria evolve so they are no longer affected by typical antibiotics, is a global concern. New research at the University of Tokyo has mapped the evolution and process of natural selection of Escherichia coli (E. coli) bacteria in the lab. These maps, called fitness landscapes, help…
