Scientists have analyzed data from Mexico's Ministry of Health to identify dengue fever hotspots. Working with epidemiologists at the University of North Texas and Universidad Autónoma de Nuevo León, the team calculated environmental and socioeconomic risk factors and mapped areas where severe outbreaks occur.

Molecular machines could treat fungal infections
Scientists show that light-activated nanoscale drills can kill pathogenic fungi.
Engineers examine drinking water management strategies
While residents in California are still dealing with damage from last month's floods -- after years of devastating droughts -- engineers are looking at better ways to manage the delivery of safe drinking water to homes. Things to consider include a changing climate, costs and sustainability.
The quail could be the unknown reservoir of Tuscany and Sicilian viruses
The quail could be the unknown reservoir of the Toscana virus (TOSV) and the Sandfly Fever Sicilian virus (SFSV), mosquito-borne pathogens that can infect domestic animals and also cause disease in humans.
Climate change may cut US forest inventory by a fifth this century
A study found that under more severe climate warming scenarios, the inventory of trees used for timber in the continental United States could decline by as much as 23% by 2100. The largest inventory losses would occur in two of the leading timber regions in the U.S., which are both...
Discovery of a circovirus involved in human hepatitis
Scientists have identified a previously unknown species of circovirus, provisionally named human circovirus 1 (HCirV-1). Circoviruses are a family of small, highly resistant DNA viruses that were initially identified in 1974 in various animal species, where they can cause respiratory, renal, dermatological and reproductive problems. HCirV-1 is a novel virus...
Engineers invent vertical, full-color microscopic LEDs
Take apart your laptop screen, and at its heart you’ll find a plate patterned with pixels of red, green, and blue LEDs, arranged end to end like a meticulous Lite Brite display.
Wildfires Are Increasingly Burning California’s Snowy Landscapes and Colliding with Winter Droughts to Shrink California’s Snowpack
The early pandemic years overlapped with some of California’s worst wildfires on record, creating haunting, orange-tinted skies and wide swathes of burned landscape.
With Rapidly Increasing Heat and Drought, Can Plants Adapt?
At a time when climate change is making many areas of the planet hotter and drier, it’s sobering to think that deserts are relatively new biomes that have grown considerably over the past 30 million years.
Health Impact of Chemicals in Plastics is Handed Down Two Generations
Fathers exposed to chemicals in plastics can affect the metabolic health of their offspring for two generations, a University of California, Riverside, mouse study reports.
