The results may surprise sourdough enthusiasts.
The popularity of genetic and ancestry services like Ancestry.com and 23andMe attests that people care about where their ancestors originated. The underlying assumption is that the geography of one's forebears affects one's genes today.
The scientific process is an iterative and collaborative journey. Research is published, others can weigh in on results, and hypotheses can be corroborated, refuted, or further refined and tested. Though it may seem like second guessing or even become contentious in some cases, this often overlooked aspect of the scientific method makes science better by continuing to challenge scientific assertio
Theories were introduced as far back as the 1960s about the possible existence of superheavy elements. Their most long-lived nuclei could give rise to a so-called "island of stability" far beyond the element uranium. However, a new study, led by nuclear physicists at Lund University, shows that a 50-year-old nuclear physics manifesto must now be revised.

Dogs synchronize their behavior with the children in their family, but not as much as they do with adults, a new study from Oregon State University researchers found.
Two family members test positive for COVID-19—how do we know who infected whom? In a perfect world, network science could provide a probable answer to such questions. It could also tell archeologists how a shard of Greek pottery came to be found in Egypt, or help evolutionary biologists understand how a long-extinct ancestor metabolized proteins.

In a brain with a neurological disorder like epilepsy, synchronization between groups of neurons can grow to a dangerous extent when a collection of brain cells begins to emit excess electricity. Researchers used a mathematical model to explore the interplay between neurons that leads to these transitions in synchronization during the onset of seizures.
Astrocytes are the most abundant type of cells within the central nervous system (CNS), but they remain poorly characterized. Researchers have long assumed that astrocytes' primary function is to provide nutrients and support for the brain's more closely scrutinized nerve cells; over the years, however, increasing evidence has shown that astrocytes can also actively promote neurodegeneration, infl
The enzymes in human cells known as histone deacetylases, or HDACs, are targets for a handful of anticancer drugs because of their ability to affect gene expression. Now, researchers have developed a new method to investigate how these enzymes work on a molecular level. This new method can also help identify more precise possible anti-cancer drug candidates at a very high pace.
Special immune cells found in the brain, microglia, play a key role in the processes that make you feel uneasy and depressed in correlation with inflammation. This is the conclusion of a study using mice. The results suggest that microglial cells contribute to the negative mood experienced during several neurological diseases, and maybe also depression.

Laser beams can be used to precisely measure an object's position or velocity. Normally, a clear, unobstructed view of this object is required. Irregular environments scatter the light beam – but as it turns out, precisely this effect can be used to obtain optimum information in difficult situations.
To predict when earthquakes are likely to occur, seismologists often use statistics to monitor how clusters of seismic activity evolve over time. However, this approach often fails to anticipate the time and magnitude of large-scale earthquakes, leading to dangerous oversights in current early-warning systems. For decades, studies outside the seismology field have proposed that these major, potent
A new modelling study predicts demand for cancer surgery will rise by 52 per cent within two decades, with low-income countries bearing the greatest burden.

Hello community I wrote a post about a widespread scientific myth; the triune brain. I first encountered this myth while reading a book called "seven and a half lessons about the brain" by neuroscientist Lisa Feldman Barrett. It has caught my attention and decided to explore it in a bit more depth. I discussed the idea behind this myth and why it's a myth in fact, laying down arguments from diffe
