Animal models of cancer metastasis to the bone 4:28

Animal models of cancer metastasis to the bone

When cancer reaches bone, the consequences can be devastating: pain, fractures, loss of movement, and sometimes death. To understand how that journey happens, and how to stop it, researchers build living models of it.

A pilot survey of selenium status and its geospatial variation among children and women in three rural districts of Zimbabwe 5:01

A pilot survey of selenium status and its geospatial variation among children and women in three rural districts of Zimbabwe

A hidden shortage of a tiny mineral may affect nearly every young child tested in three rural districts of Zimbabwe. And the risk is not spread evenly: where a family lives appears to matter.

Precise bulk density measurement of planktonic foraminiferal test by X-ray microcomputed tomography 3:43

Precise bulk density measurement of planktonic foraminiferal test by X-ray microcomputed tomography

Tiny drifting shells help scientists reconstruct what the ocean was like in the past. Now, a scan can measure not only their shape, but how densely built they are, without breaking them open.

Eu3+ Complex-Based Superhydrophobic Fluorescence Sensor for Cr(VI) Detection in Water 4:21

Eu3+ Complex-Based Superhydrophobic Fluorescence Sensor for Cr(VI) Detection in Water

A tiny drop of water can reveal a dangerous pollutant without a large laboratory machine. This sensor turns the drop itself into a simple warning signal: the brighter light disappears when hexavalent chromium is present.

Assessing the association between tea intake and risk of dental caries and periodontitis: a two-sample Mendelian randomization study 3:34

Assessing the association between tea intake and risk of dental caries and periodontitis: a two-sample Mendelian randomization study

Tea is often treated as a healthy choice for your mouth. But this study found a genetic clue pointing in the opposite direction for gum disease, while finding no link with cavities.

Validation of a novel numerical model to predict regionalized blood flow in the coronary arteries 3:49

Validation of a novel numerical model to predict regionalized blood flow in the coronary arteries

A heart artery is not just one pipe carrying one stream of blood. Its smaller branches constantly draw blood away, and a computer model may now estimate where that flow goes, without measuring every drop directly.

Effectiveness and Safety of the MVA–BN Vaccine against Mpox in At-Risk Individuals in the United States (USMVAc) 4:36

Effectiveness and Safety of the MVA–BN Vaccine against Mpox in At-Risk Individuals in the United States (USMVAc)

Mpox seemed to fade from the headlines, but the risk did not disappear. In U.S. health records, people who received both recommended vaccine doses had far less mpox than similar unvaccinated people.

Combined SERS-Raman screening of HER2-overexpressing or silenced breast cancer cell lines 4:31

Combined SERS-Raman screening of HER2-overexpressing or silenced breast cancer cell lines

Breast cancers that look alike can behave very differently. This study uses light to find a key cancer marker on individual cells, and then reveals a surprising change that remains even after that marker is silenced.

Highly accurate protein structure prediction with AlphaFold 4:07

Highly accurate protein structure prediction with AlphaFold

Every cell depends on proteins, but scientists have seen the shape of only a tiny fraction of them. AlphaFold showed that a sequence of chemical letters can be enough to predict a protein’s three-dimensional form with near-experimental accuracy.

Reinforced Labels: Multi-Agent Deep Reinforcement Learning for Point-Feature Label Placement 3:26

Reinforced Labels: Multi-Agent Deep Reinforcement Learning for Point-Feature Label Placement

A map can spend half its production time deciding where words should go. This study teaches each label to move out of the way of the others, and the result is more complete, clearer maps, at a steep cost in time.

Access to Healthcare Services among Thai Immigrants in Japan: A Study of the Areas Surrounding Tokyo 3:36

Access to Healthcare Services among Thai Immigrants in Japan: A Study of the Areas Surrounding Tokyo

Many Thai immigrants in Japan understood why health insurance matters and viewed it positively. Yet almost half reported having no insurance, and people without clear residency status were especially unlikely to have it.

The burden of colorectal cancer attributable to dietary risk in Middle East and North African from 1990 to 2019 3:16

The burden of colorectal cancer attributable to dietary risk in Middle East and North African from 1990 to 2019

Bowel cancer is rising in lower- and middle-income countries, and this study finds that the share linked with diet increased across all 21 countries examined. What we eat may be part of a changing regional health story.
