In a computer model, tiny invisible pores in rock act as bridges that boost fluid flow.

Rocks like limestone have two kinds of pores: big ones you can see, and tiny ones too small to see clearly. A new computer model shows the tiny pores act like bridges that connect the big pores together. This bridging boosts how much fluid can flow through the rock overall. The natural arrangement of tiny pores matters a lot. Scrambling that arrangement in the simulation made flow worse than the real pattern.

The number over 100 times

The range in permeability, or flow ease, measured across three carbonate rock samples.

Three rock samples, computer model only, not tested in real wells.

Two blood tests can track late-stage tau tangle buildup in Alzheimer's disease.

Two blood markers rise later in Alzheimer's disease than other markers do. They go up when sticky tau tangles build up in the brain, which doctors usually see only with brain scans. One marker, combined with another blood test, can sort patients into disease stages. This blood-based staging matched brain scans closely and predicted how memory and thinking would change over time.

What it could change A blood test stage system matched brain scans and predicted future memory decline.

Shown in a research cohort with brain scans, not yet tested in the general public.

One research cohort only, not yet tested broadly in the public.

In mice, a brain region grows more reactive step by step as stress leads to depression-like behavior.

A small brain area called the habenula changes over time in mice under long-term stress. Scientists tracked gene activity and brain cell signals in this area and saw cells react more strongly to bad experiences as stress went on. These changes matched the growth of depression-like behavior. The fast-acting antidepressant ketamine reversed the changes, and calming the cells early also reduced depression-like symptoms.

What it could change Calming specific brain cells early blocked depression-like behavior in stressed mice.

Shows a possible early window for treatment in a mouse model, not yet tested in people.

Male mice only, lab study, no human data yet.

A computer model guided the design of a light reactor that evenly lights 16 vials at once.

Light-driven chemistry depends on getting light to hit the reaction mix evenly, but reactor shapes are hard to design by hand. Scientists built a computer copy of a photoreactor, checked it against real light measurements, and used a smart search program to test shapes and layouts. They found shapes that spread light evenly across 16 reaction vials while capturing more light overall. Real chemical reactions run in the new design matched what the computer predicted.

The number 16 vials

The number of reaction vials the optimized reactor lights evenly at the same time.

One reactor design, one reaction tested, lab only so far.

Water pumping near borders in shared underground water layers can affect neighboring countries more than expected.

Underground water stored in layers that cross country borders feeds over a third of the world's farmland that uses groundwater for irrigation. Few countries have formal deals to share and manage this water together. A new analysis of about 116,000 wells across 426 shared water layers found that water pumping and water loss are not worse on average than in water layers inside just one country. But both tend to pile up near borders, meaning one country's water use is more likely to affect its neighbor there.

The number 35% of global groundwater-irrigated cropland

The share of groundwater-fed farmland that sits above water layers shared by more than one country.

Global well data only, no direct measure of cross-border harm.
