Funnel plots are a form of scatter diagram which are widely used to visualize possible publication bias in the context of a meta-analysis. In a funnel plot, each data point represents one of the studies in the meta-analysis. The x-axis shows the effect size reported by the study, while the y-axis represents the standard error of the effect size, which is usually inversely related to the sample size.
In theory, t
Their vehicles will “inch” to the starting line and explode into motion to kick off a marathon 36-hour race that will have covered less than the width of a human hair by the time a victor is crowned. The vehicles participating in the race are custom-built tuners assembled out of a few hundred atoms by researchers, which are propelled across the surface of a gold disk by a st
Every waking moment, countless stem cells inside our bodies are dividing in order to replace worn out biological machinery. But every time these perfectly healthy cells divide, roughly three mistakes occur in the genetic code—no one’s perfect. These mutations, though unpredictable, are typically benign, but sometimes this molecular game of Roulette takes an unlucky turn.
“Most of the time these mutations don’t do any harm; they’re in junk
Over time, this snow – along with sediment mineral grains – accumulates, burying previous layers. In Denmark’s Aarhus Bay, for example, digging ten meters down beneath the seafloor is like going 8,700 years
These stubborn, damaged cells can accumulate in the body over time, and they can accelerate the aging process and cause the onset of disease. But there might be a way to put these lingerers out of their misery. Peter de Keizer, a researcher of aging at Erasmus University Medical Center in the Netherl
That’s the idea behind a new beer from San Diego’s Stone Brewery made from the city’s recycled wastewater. Their aptly named Full Circle Pale Ale uses water from Pure Water San Diego, a water treatment company that aims to supply one-third of the city’s water within the next two decades. They’ve partnered with the brewery to give the much-maligned concept of “toilet to tap” a
For more than a century, the dinosaur family tree was understood as having a very early split into two branches:
Climate change in 2016 — and continuing into 2017 — has brought the planet into “truly uncharted territory”
Yesterday I reported that even though the warming influence of El Niño is long gone, February of 2017 brought very little letup in global warming.

Now, the World Meteorological Organization is confirming that 2016’s “extreme weather and climate condit
Brigadier Abdullah Bin Sultan, director of the Future Shaping Centre of Dubai Police, made the announcement Monday during a police forum held in the city. By 2030, Dubai officials hope that up to 25 percent of their police force will be artificially intelligent. This, from the same crime-fighting organization that has Lamborghini, Ferrari and Bentley patrol cars parked in its garage.
Even though the warming influence of El Niño is long gone, and 2017 was expected to offer some relief from record temperatures set last year, February saw very little letup in global warming.
And now there’s at least a chance that 2017 as a whole could be headed for the record books.
Meanwhile, the Trump administration is moving aggressively to halt U.S.
At Loughborough University we investigated the effect of a hot bath on blood sugar control (an important measure of metabolic fitness) and on energy expended (number of calories burned). We recruited 14 men to take part in the study. They were assigned to an hour-long soak in a hot bath (40˚C) or an
Biologists have traditionally assumed that all six elements were prerequisites, as each one is found in several of life’s most essential molecules. But what if earlier life forms weren’t
You’ve just used the “method of loci,” which is a fundamental memorization technique that dates back to ancient Greece and is employed by champion memory athletes. Radboud University Medical Center neuroscientist Martin Dresler, lead author of a study recently published in the journal Neuron,
The authors are Himanshu Bansal and colleagues of India. The senior author, Prasad S Koka, is the Editor-in-Chief of the Journal of Stem Cells where the paper appeared, which raises questions about whether the manuscript received a thorough peer review. Koka is actually an author on all five of the research papers published in that issue of the journal. But that’s a minor issue compared
The film release was part of a project headed by Lawrence Livermore National Laboratory (LLNL) weapons physicist Greg Spriggs which aimed to digitize and preserve thousands of films documenting the nation’s nuclear history. The endeavor required an all-hands-on deck approach from archivists, film experts and software engineers, but the team says that this digitized database is alre

While the masses of ice that float atop the planet have been in steady decline over the past few decades, scientists haven’t been able to say how much of the losses are attributable to human-driven climate change and how much is simply the result of periodic swings in climate conditions. While the scientific consensus is that human activities h
