Dengue infection risk swings from about 1% to over 50% a year across Timor-Leste.

Dengue infection risk is not the same everywhere in Timor-Leste. In one area, only about 1% of people catch it each year. In another area, over half the people catch it each year. Drier air was linked to higher risk, and the biggest risk was found along the northern and eastern coasts, including two major cities.

The number 1% to 52% per year

The range in yearly dengue infection risk found across different neighborhoods in Timor-Leste.

One country survey of 4,780 people, based on blood tests, not live case tracking.

In lab-grown immune cells, DNA folding lets past signals boost future immune responses.

Immune cells called macrophages can remember a past chemical signal. They do this by folding their DNA into a new shape. This folding brings gene switches closer to the genes they control. As a result, the cell reacts faster and stronger the next time it meets a germ signal, even after the first signal is gone.

What it could change A way immune cells store memory of past signals by refolding their DNA shape.

Shows DNA folding changes, not accessibility or histone marks, drive this memory effect in lab cells.

Lab-grown human immune cells only, no animal or patient data yet.

In lab studies, common virus infections can help tumors grow and spread faster.

Getting a common infection, like flu or COVID, might change how cancer grows inside the body. In lab studies, infections cause swelling and immune changes that can help tumors grow and spread. But the same immune response can sometimes attack cancer instead of helping it. Doctors do not yet know which effect wins in a real patient.

What it could change Common infections can push the body's defenses to either help or hurt a tumor.

Shows a lab-based link between infection-driven inflammation and cancer growth, not a proven human effect.

Lab and animal evidence only, not yet tested for real patients.

A chemical mesh trick lets bendable solar cells hit 25.13% efficiency, near rigid-cell levels.

A new chemical method makes bendable solar panels almost as good as rigid ones, even at large sizes. Two chemicals get mixed into the solar material while it forms. They link together into a support mesh. This mesh makes the panel more stable and easier to build at large sizes without losing power.

The number 25.13% efficiency

The sunlight-to-electricity conversion rate of the best flexible solar cell made with this method.

Lab prototypes only, no real-world product testing yet.

Strong government and backup food supplies protect countries from hunger during crises, even severe ones.

A country hit by a crisis does not always end up hungrier. Some countries in Asia faced severe shocks but still kept hunger from rising much. The difference came down to things like good government, backup food sources, higher income, and strong community trust. These factors helped countries limit hunger increases even when shocks were bad.

What it could change Good government and backup food sources can break the link between crisis severity and hunger.

Shows which country-level factors weaken the tie between shocks and rising hunger.

Country-level data only, not a single-nation deep test.
