An experiment at a San Diego beach is turning the seawater pink, temporarily, in the name of science.
Reducing their natural signals: How sneaky germs hide from ants
Not only humans are social, ants are too. Group members are taking care of sick ones by providing collective hygiene measures. This presents germs with a task. They must circumvent the immunity of an individual ant and avoid the group's healthcare. A new study reveals that germs develop a sneaky...
Study provides an explanation and potential solution for severe graft-versus-host disease
Researchers found that alterations in the gut microbiome that are linked to graft-versus-host disease severity are connected to an increase in oxygen levels in the intestine that follows immune-mediated intestinal damage. Pharmacologically reducing intestinal oxygen levels alleviated the microbial imbalance and reduced the severity of the condition in animal models.
Human brain organoids respond to visual stimuli when transplanted into adult rats
Researchers show that brain organoids -- clumps of lab-grown neurons -- can integrate with rat brains and respond to visual stimulation like flashing lights.
Molecular machines could treat fungal infections
Scientists show that light-activated nanoscale drills can kill pathogenic fungi.
Mapping Mexico’s dengue fever hotspots
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.
New research turns what we know about bird window strikes inside-out
New research reveals that decals intended to reduce incidents of bird window strikes -- one of the largest human-made causes of bird mortality -- are only effective if decals are placed on the outside of the window. Researchers found that the patterns on the films and decals placed on the...
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.
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...
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...
