A new index of scientific output has been released and it finds that the United States continues to dominate in research, bolstered by the private sector accounting for nearly 70 percent of science funding, where most other developed countries instead rely on government.

The analysis factored in the number researchers as percentage of population, patents, papers released, and GDP spending. 
Scholars recently characterized plasma levels of the biomarker dehydroepiandrosterone (DHEA) and its sulfated form (DHEAS) – jointly referred to as DHEA(S) – to be biological determinants of chemobrain, difficulties related to memory and attention in cancer patients even months after completing their treatment.

DHEA(S) are neurosteroids that help to regulate brain development, but it was previously unknown whether their levels correlate with cognitive function or are associated with the onset of chemobrain.

The study showed that early-stage breast cancer patients with higher plasma DHEAS levels prior to chemotherapy were found to have a lower risk of developing chemobrain in the specific domains of verbal fluency and mental acuity.
When we think of Mt. Everest, it's usually imagery like Sir Edmund Hillary and his guide Tenzing Norgay in parkas and with oxygen tanks making the hazardous 29.000 climb. And then there are the dead bodies, nearly 300 of them, those who perished on the trek to the summit.

What we don't think of is a man running, yet that is what Kilian Jornet Burgada did part of the way in famous photos - and then after 26 hours and 31 minutes, the fastest climb ever(1), he came back down, rested, and did it again, all within a week.

Poor people live in areas with more pollution, but pollution is relative in 2019.

Smart spacesuits and solar surfing may sound like the stuff of science fiction, but they are just two of the technology concepts NASA ha

Experimental particle physics, the field of research I have been involved in since my infancy as a scientist, consists of folks like you and me, who are enthusiastic about constructing new experiments and testing our understanding of Nature. Some spend their life materially designing and building the apparata, others are more attracted by torturing the data until they speak. 

To be precise, data analysts can be divided further into two classes, as I was once taught by my friend Paolo Giromini (a colleague in the late CDF experiment, about whose chase for new physics I have written in my book "Anomaly!"). These are aptly called "gatherers" and "hunters".
To say ‘business ecosystem’ or ‘innovation ecosystem’ is to commit the teleological fallacy. That means assuming a purpose where there is no purpose.

Charles Darwin said species evolve to adapt to changing environments. Natural ecosystems – species and their environments – have no ‘purpose’; they just are.

Now, if you believe in a creator deity, you might hold that biological ecosystems do have a (divine) purpose. We’ll come back to this point.
Environmentalists may hate science but they love to ignore inconvenient truths about alcohol - namely that it is a toxic carcinogen the way they wish BPA, atrazine, fracking, vaccines (insert whatever they are raising money on this week) could be.

Almost nobody seems to report the positive side of our recent climate change action. It’s remarkable what we’ve done in two years, which gives us much hope that we can indeed rise to the challenge. I have never in my life seen such a coming together of nations worldwide to solve a problem. Three years ago, after the slow progress of the Kyoto protocol agreement, all this would have seemed impossible. There is a lot of publicity about what we aren't doing yet, but hardly anyone talks about what we have already done. That's the key to success, to build on what we already have and what we have already done.

Testosterone is the main sex hormone in men. It’s best known for its role in the development of male sexual characteristics and physical features, but there are also many surprising and lesser known functions of testosterone that make it an important hormone in health and disease. Identifying whether someone has too much or too little testosterone can predict future diseases and even treat them. But knowing what is high, low or normal for an individual isn’t straightforward.
