Clinical visits by patients suffering ocular surface eye conditions more than doubled during times when ambient particulate matter from air pollution was in the atmosphere, signaling a possible association between climate change and ocular health, according to a new study.
Decline in West African coastal fish stocks threatens food security and livelihoods
Fish stocks along the West African coast have declined significantly over the past five decades, threatening food security and the livelihoods of the fishing communities that depend on them, according to a new study.
‘Walk this Way’: How ants create trails to multiple food sources
Researchers have discovered that in a foraging ant's search for food, it will leave pheromone trails connecting its colony to multiple food sources when they're available, successfully creating the first model that explains the phenomenon of trail formation to multiple food sources.
Achilles heel of antibiotic-resistant bacteria
To stem the surging antibiotic resistance public health crisis, scientists seek solutions inside the mechanics of bacterial infection. A new study has found a vulnerability related to magnesium availability. This limitation potentially could be exploited to stop the spread of antibiotic resistance.
Earliest evidence of humans using fire to shape the landscape of Tasmania
Some of the first human beings to arrive in Tasmania, over 41,000 years ago, used fire to shape and manage the landscape, about 2,000 years earlier than previously thought.
New study shows how salmonella tricks gut defenses to cause infection
A study uncovered how Salmonella, a major cause of food poisoning, can invade the gut despite the presence of protective bacteria.
Biologists reveal the genetic ‘switch’ behind parrot color diversity
From the Carnival in Rio de Janeiro to the shoulders of pirates: parrots are synonymous with color for people across the world. In a new study, scientists uncover a 'switch' in the DNA of parrots that controls their wide gamut of colors.
Generation of rat offspring from ovarian oocytes by cross-species transplantation
Attempts to obtain eggs and offspring using oocytes in ovary have been made for keeping desirable traits in livestock, preserving human fertility, etc. Ovarian transplantation, one of those methods, has been established and widely used. Although transplantation to different species is expected to bring benefits, it is still too difficult...
Scientists transform blood into regenerative materials, paving the way for personalized, blood-based, 3D-printed implants
Scientists have created a new 'biocooperative' material based on blood, which has shown to successfully repair bones, paving the way for personalised regenerative blood products that could be used as effective therapies to treat injury and disease.
Optical biosensor rapidly detects mpox virus
Researchers have developed an optical biosensor that detects the virus that causes mpox. The technology could make diagnosis much faster and cost-effective as the disease continues to spread worldwide.
