The 1949 letter by the physicist and Nobel laureate discusses bees, birds and whether new physics principles could come from studying animal senses.
It's a position still being realised within physics to this day, with a growing body of research and understanding of how animals such as birds and bees find their way around.
Now a study led by RMIT University in Melbourne, Australia, discusses how recent discoveries in migratory birds back up Einstein's thinking 72 years ago.
Scientists have begun the search for extraterrestrial life in the Solar System in earnest, but such life may be subtly or profoundly different from Earth-life, and methods based on detecting particular molecules as biosignatures may not apply to life with a different evolutionary history.
PULLMAN, Wash. - Rush hour will likely return when pandemic lockdowns lift, but a new study suggests that congestion pricing--policies that charge tolls for driving during peak hours--could not only cure traffic jams but also convince motorists it is safe to buy smaller, more efficient cars.
COLUMBUS, Ohio - Neighborhoods without opioid treatment providers likely serve as a widespread barrier to care for those who are ready to seek help, a new study has found.
The study, led by researchers at The Ohio State University, appears today (May 12, 2021) in the journal PLOS ONE.
Elephant Seals' Extreme Diving Allows Them to Exploit Deep Ocean Niche
The human brain is a vast network of billions of biological cells called Neurons which fires electrical signals that process information, resulting in our sense and thoughts. The ion channels of atomic scale in each neuron cell membrane plays a key role in such firings that opens and closes the ion flow in an individual cell by the electrical voltage applied across the cell membrane, acting as a "biological transistor" similar to electronic transistors in computers.
Strawberry production is one of the driving forces in the Spanish agriculture sector, as strawberries are highly valued for their organoleptic characteristics and health benefits. These two factors, their economic relevance, and the value that consumers assign them, make this fruit an object of scientific research from multiple perspectives, including that of food safety.
Central to any technological progress is the enrichment of human life. The internet and wireless connectivity have done that by allowing not only virtually anyone anywhere to connect real time, but by making possible connections between humans and a range of intelligent devices both indoors and outdoors, putting smart cities on the horizon.
The inhibition of pathological protein-protein interactions is a promising approach for treating a large number of diseases, including many forms of cancer. A team of researchers has now developed a bicyclic peptide that binds to beta-catenin--a protein associated with certain types of tumor. The secret of their success is the cyclic nature and the hairpin shape of the peptide, which mimics a natural protein structure, they report in the journal Angewandte Chemie.
In a new study from Lund University and the University of Gothenburg, patients were interviewed about their experiences ten years after undergoing obesity surgery. The results show that the effect on eating and weight regulation persisted, whereas other problems, such as feelings of guilt about still not being healthy enough, remained.
"This is one of few follow-ups from a patients perspective so long after surgery", says My Engström, researcher in nursing at the University of Gothenburg.
The multiplexing capability of fluorescence microscopy is severely limited by the broad fluorescence spectral width. Spectral imaging offers potential solutions, yet typical approaches to disperse the local emission spectra notably impede the attainable throughput and place substantial constraints on temporal resolution. Tunable bandpass filters provide a possibility to scan through the emission wavelength in the wide field. However, applying narrow bandpasses to the fluorescence emission results in inefficient use of the scarce signal.
Tuberous Sclerosis Complex (TSC) affects between one and two of every 10,000 new-born babies. This genetic disease leads to the formation of benign tumours which can massively impair the proper functioning of vital organs such as the kidneys, the liver and the brain. The disease affects different patients to varying degrees and is triggered by mutations in one of two genes, the TSC1 or TSC2 gene. An interdisciplinary team of researchers led by biochemists Prof. Daniel Kümmel and Dr.
Loss of smell, or anosmia, is one of the earliest and most commonly reported symptoms of COVID-19. But the mechanisms involved had yet to be clarified. Scientists from the Institut Pasteur, the CNRS, Inserm, Université de Paris and the Paris Public Hospital Network (AP-HP) determined the mechanisms involved in the loss of smell in patients infected with SARS-CoV-2 at different stages of the disease. They discovered that SARS-CoV-2 infects sensory neurons and causes persistent epithelial and olfactory nervous system inflammation.
Are you empathic, generous and altruistic? In short, do you possess that specific personality trait defined as agreeableness in the language of psychologists? New research from SISSA recently published in the journal NeuroImage sheds light on brain mechanisms underlying this trait.
When Museums closed their doors in March 2020 for the first COVID-19 lockdown in the UK a majority moved their activities online to keep their audiences interested. Researchers from WMG, University of Warwick have worked with OUMNH, to analyse the success of the exhibitions, and say the way Museums operate will change forever.Caption: Compton Verney's homepage for the Cranach exhibition which opened in March 2020 Credit: Compton Verney
