Darwin"s short-beak enigma solved: Mutation in the ROR2 gene is linked to beak length in domestic pigeons
Charles Darwin was obsessed with domestic pigeons. He thought they held the secrets of selection in their beaks. Free from the bonds of natural selection, the 350-plus breeds of domestic pigeons have beaks of all shapes and sizes within a single spec.....»»
Arctic heat waves linked to sea ice loss, new study reveals
Amid global warming, heat waves are striking even the Arctic, a region once considered immune to such extreme weather events. Recent research reveals that these heat waves, particularly in the Barents-Kara Sea (BKS) during the boreal autumn, are not.....»»
Using metal ion-linked nanostructures to improve immune response and boost breast tumor treatment
Immune checkpoint blockade (ICB) is one of the primary methods of tumor immunotherapy. However, clinical data have shown that only a portion of patients respond to ICB treatment. Since the tumor's immune-suppressive environment plays a crucial role i.....»»

"Silent" mutations found to have repercussions beyond their own gene
Genetic disorders—like cystic fibrosis and Huntington's disease—are considered incurable, with gene mutations occurring in essentially every cell of the body. Gene mutations occur when one nucleotide in a codon is switched. In non-synonymous muta.....»»
Uncertainty is a key factor in the relationship between work injury and mental health, research shows
Mental health and workplace injuries are known to be closely linked, but there are significant gaps in our deeper understanding of that bidirectional relationship. How does one affect the other, what moderates the relationship and what are the long-t.....»»
Short empathy training program found to measurably improve classroom behavior
A study involving 900 students in six countries found that a short program of empathy lessons led to measurable, positive changes in their conduct, emotional awareness and curiosity about different cultures......»»
Gaps in firearms relinquishment laws may weaken court orders, increase illegal gun possession
State and federal laws across the United States prohibiting firearm possession in cases of domestic violence often lack enforcement mechanisms, which may lead to continued possession of firearms despite court orders, according to a University of Mich.....»»
Moths may use disco gene to regulate day/night cycles
How does one species become two? If you're a biologist, that's a loaded question. The consensus is that, in most cases, the process of speciation occurs when individuals from a single population become geographically isolated. If they remain separate.....»»
Authors propose multi-method framework for climate event attribution
At the two most recent meetings of the United Nations Framework Convention on Climate Change, delegates agreed to establish a fund to help developing nations suffering loss and damage due to events linked to climate change, such as floods, heat waves.....»»
Exploring Darwin"s longstanding interest in biological rhythms
A close reading of Darwin's work suggests a deep interest in cyclical events. Rhythmic phenomena in nature—today the subjects of the field of chronobiology—have been studied since at least the 18th century. In a perspective, Tiago Gomes de Andrad.....»»
Elon Musk foreclosing on former home of actor Gene Wilder
Tesla's CEO sold the home, which is down the street from where Lee Iacocca used to live, in 2020 when he was getting rid of some possessions......»»
Darwin"s fear was unjustified: Study suggests fossil record gaps not a major issue
Fossils are used to reconstruct evolutionary history, but not all animals and plants become fossils and many fossils are destroyed before we can find them (e.g., the rocks that contain the fossils are destroyed by erosion). As a result, the fossil re.....»»
Record-breaking drought in southern China linked to Eurasian warming and tropical sea surface temperature
Southern China experienced an extreme drought that persisted from summer to autumn in 2022, ranking as the most severe drought since 1980. The reason for the occurrence of this extreme drought event was investigated. It shows that both the Eurasian w.....»»

New genetic sensor for DNA methylation discovered
DNA methylation is a process in which a methyl group is attached to the cytosine base of the DNA molecule, and is a major way that DNA is epigenetically marked. Epigenetic modifications can act as on–off switches to regulate gene expression and hel.....»»
Adversaries love bots, short-lived IP addresses, out-of-band domains
Fastly found 91% of cyberattacks – up from 69% in 2023 – targeted multiple customers using mass scanning techniques to uncover and exploit software vulnerabilities, revealing an alarming trend in attacks spreading across a broader target base. In.....»»
Heaviest antimatter observation yet will fine-tune numbers for dark matter search
In experiments at the Brookhaven National Lab in the US, an international team of physicists has detected the heaviest "anti-nuclei" ever seen. The tiny, short-lived objects are composed of exotic antimatter particles......»»
How particles of light may be producing drops of the perfect liquid
The world's largest and most powerful particle accelerator may be producing the world's tiniest droplets of liquid, right under scientists' noses. Researchers are digging into this subatomic enigma......»»
