On average, researchers’ impact dropped by one-half to two-thirds over their careers.

Researchers made the find using an algorithm that purportedly distinguishes between mutations that were selected for and those that came along for the ride by coincidence, a feat that has long eluded scientists.

Despite increasingly strict journal policies requiring the release of computational code files along with research papers, many scientists remain reluctant to share—underscoring the need for better solutions.

The basic reproductive R0, along with the more malleable effective reproduction number Re, are centerpieces of most epidemiological models that are informing government responses to COVID-19.

The SARS-CoV-2 pandemic has revealed the limitations of R0 as no other disease outbreak has before, at a time when policymakers need accurate forecasts.

Lacking many diagnostic test results from the first major outbreak, researchers have been left to scour other sources for clues about what happened in the early days of the pandemic.

It can take days for each death to be recorded in official statistics. “Nowcasting” estimates the actual occurrence of deaths, and the true peak of the pandemic.

A new report from the National Science Board identifies changes in the US’s global R&D investment and output, as well as in the country’s science and engineering workforce in recent years.

Independent scientists say the original analysis is flawed; the authors stand by their work and are seeking outside statisticians to reanalyze the data.

In service of an arbitrary threshold, p-values often lead researchers to make poorly supported claims and ignore interesting but insignificant results, scientists argue.

The cofounder of the EQUATOR Network devoted his career to boosting transparency and improving the quality of clinical research.

The correspondence points to routine data-massaging at a high-profile lab.

Despite an overall decrease in the number of US cancer deaths, some cancer types are on the rise, and disparities remain between genders and ethnicities.

This year's life sciences salary survey turned up some interesting trends in the U.S. and around the world.

In the 1930s, parapsychologist Joseph Banks Rhine aimed to use scientific methods to confirm the existence of extrasensory perception, but faced criticisms of dubious analyses and irreproducible results.

An analysis of the widely used technique calls into question the validity of 40,000 studies.

There’s a right way and a wrong way to boost the statistical sensitivity of this type of clinical studies.

The American Statistical Association offers guidance on best practices for the oft-misused tool.
