Как находка в пещере в Нью-Мексико поменяла наши представления о том, на каких планетах возможна жизнь - BBC News Русская служба

Ученые, исследующие пещеры Карлсбад в Нью-Мексико, обнаружили микроорганизмы, которые осуществляют фотосинтез в полной темноте с помощью света, близкого к инфракрасному диапазону. Это означает, что планеты, где возможна жизнь, можно искать у более холодных звезд, которых во Вселенной гораздо больше.

"
Forschende messen erstmals Ionisation in Dunkelwolke
"
".. Forschungsteam hat erstmals die Wirkung kosmischer Strahlung in einer kalten Molekülwolke direkt gemessen. Die Beobachtung zeigt, wie stark energiereiche Teilchen das Gas in diesen lichtlosen Regionen beeinflussen, in denen Sterne entstehen."

NIR Biomass Analysis Gone Wrong

I recently had to audit a production NIR spectroscopy system used for biomass analysis. On paper, it sounded impressive: “state of the art chemometrics,” “advanced multivariate calibration,” “industry ready models.” In reality? It was a textbook example of how to do NIR modeling wrong in ways that quietly transfer risk and liability from the software vendor straight onto the client’s balance sheet. If your organization is buying NIR-based biomass analytics “as a service,” […]

It took a while, but I'm finally back to writing my blog 😎

The first installment for 2026 is an easy introduction to calculating information #entropy for optical spectra (or for any signal, really).

In my blog, I focus on #data analysis (#chemometrics, machine learning) applied to optical and near-infrared #spectroscopy Smoothing, or denoising, is one of the most common steps to work with spectroscopy data, and information entropy can be used as a criterion to guide the smoothing process.

Better still, the entropy of the derivative of a signal can help with that, because it accounts for the shape of the signal more naturally.

Near Infrared Light Reduces Inflammation via TLR4 In Vitro [2022]

video discusses this article:
Infrared light therapy relieves TLR-4 dependent hyper-inflammation of the type induced by COVID-19
https://pmc.ncbi.nlm.nih.gov/articles/PMC8451450/

"The inflammatory response was induced in cell cultures by LPS, followed by exposure to 720 nm LED light source at an intensity of 6 W/m2 for 10 min at 12-h intervals (see methods). ... At the end of the 48-h treatment period, cells were harvested and gene expression analysis performed. The results showed an approximately 50% reduction in gene expression of all of these markers in response to LED infrared exposure (Figure 4). ..."
