wjb3··on Microbiome composition varies based on sampling time, mouse study finds
This study found that the microbiome composition varies based on the time of sampling. How do you think this variability might affect the reproducibility of microbiome research? What are some practical ways researchers could standardize sampling times to improve consistency across different studies?

wjb3··on Synaptic anomalies in autistic people support imbalance hypothesis
Let’s review.

Here (as in the article), by imbalance, we are referring to that “between inhibitory and excitatory signals in the brain” (i.e., the imbalance “in the number of excitatory and inhibitory synapses in the prefrontal cortex [that] may affect broader brain function and contribute to some of the cognitive and behavioral traits of autism.”

The interventions I am curious about are (per my question) “targeted” to “modify these synaptic structures to enhance cognitive and social functions.” It’s puzzling to me that you would not only choose to interject the word fix, but also (even more inexplicably) to put it in quotes, as if it were my word choice rather than your own- and finally, to follow it with “It's important to use the correct terms to avoid biased frames and conclusions.” Indeed.

wjb3··on Synaptic anomalies in autistic people support imbalance hypothesis
One area I'd love to see explored further is the potential for targeted interventions that could modify these synaptic structures to enhance cognitive and social functions. Given the plasticity of the brain, are there promising avenues for therapeutic approaches that could recalibrate these imbalances?
wjb3··on Hack Your Way to Scientific Glory (2016)
When you say that eLife is "very rigorous," could you elaborate on what specific aspects of their review process or criteria you find particularly stringent, and how those compare to the review processes of Nature/Cell?
wjb3··on Hack Your Way to Scientific Glory (2016)
An excellent demonstration of how easy it is to manipulate data to find significant results - it brings to light (again) the pervasive issue of data dredging in research, where researchers, intentionally or unintentionally, keep testing hypotheses until they find something publishable, thereby undermining the integrity of scientific findings and highlighting the importance of preregistration and replication studies.

How can we shift the academic incentives away from "publish or perish" toward promoting transparency and rigorous methodology in research? Are any of the current attempts moving the needle?

wjb3··on Historic Moon Mission Moves China Ahead in Space Race with U.S.
Under the Outer Space Treaty, signed by more than 100 countries, including the U.S. and China, whoever builds a moon base could argue it is entitled to establish a 100-kilometer safety perimeter to protect its equipment.

wjb3··on Regional response to light illuminance across the human hypothalamus
Previous research has shown that light exposure increases alertness, but this is one of the first studies to pinpoint how it influences the human brain at the neural level. I'll be outside if you need me.

wjb3··on Hybrid Quantum Interface for Telecom Light Storage and Retrieval
This technology allows for the secure transmission of information, such as a fingerprint to a bank, without the risk of interception because the data does not travel in a traditional sense. This form of secure quantum teleportation could revolutionize secure communications, offering a glimpse into the future of how data may be transferred safely over long distances, potentially leading to the development of a full-fledged quantum internet.

The study involved using entangled photons and a nonlinear detector, which, while not strictly teleportation as seen in science fiction, represents a major step towards real-world quantum communication systems. The team is optimistic that further advances could enhance the efficiency of these detectors, bringing the concept closer to practical use and integrating it into global communication networks.

TL;DR

The discussion is framed around a detailed examination of the evidence related to the early COVID-19 cases, including contradictions and ambiguities in the reported connections to the Huanan seafood market. It questions the initial assumption that the virus directly emerged from this market, considering other potential sources, including the possibility of a lab-associated incident.

Alexander contrasts various points of view, highlighting the complexity of drawing definitive conclusions from the available data. The debate also touches on epidemiological data, such as the early spread of the virus and its genetic mutations, to scrutinize the lab leak hypothesis further. The review uses a critical lens to assess the strength of the evidence and the reasoning presented by different stakeholders in the debate.

wjb3··on Will the debate about 'psi' ever be settled?
A recent debate on the existence of psi (supposed parapsychological phenomena); whether you're a skeptic or otherwise, this lively discussion is well worth a read.
wjb3··on They're young and athletic. They're also ill with a condition called POTS
First described more than 150 years ago, the syndrome has proliferated since the coronavirus pandemic. Before 2020, 1 million to 3 million people suffered from POTS in the United States, researchers estimate. Precise numbers are difficult to come by because the condition encompasses a spectrum of symptoms, and many people have still never heard of it. Recent studies suggest 2 to 14 percent of people infected with the coronavirus may go on to develop POTS.
wjb3··on Publishing negative results is good for science
ABSTRACT

Scientists face challenges in publishing negative results, because most scientific journals are biassed in accepting positive and novel findings. Despite their importance, negative results often go unpublished, leading to duplication of efforts, biassed meta-analyses, and ethical concerns regarding animal and human studies. In this light, the initiative by Access Microbiology to collect and publish negative results in the field of microbiology is a very important and valuable contribution towards unbiassed science.

wjb3··on Elite athletes and gamers have higher than average visual temporal resolution
The research, published in Plos One, found that some people reported a light source as constant when it was in fact flashing about 35 times a second, while others could still detect flashes at rates of greater than 60 times a second.
wjb3··on Psychophysiological and emotional effects of human–Dog interactions by activity
Perhaps most intriguing was that playing with the dog increased both alpha and beta together in the prefrontal cortex, the brain’s control center for complex cognitive behaviors, personality, and decision-making. This suggests that playful interaction with dogs could promote a calm yet attentive mental state especially conducive to learning, creativity and emotional balance.
