Ants make their own ant-ibiotic for infected wounds
Ants have a gland that makes an antibiotic, and use it in response to pheromones. Enlarge / An ant carrying away one of the termites it preys on. (credit: Wikimedia Commons) Although humans may think we are alone in crea.....»»
Cow challenge study should help turn tables on H5N1 in dairy herds
Animal challenge studies completed by U.S. Department of Agriculture (USDA) scientists show that infecting dairy cows with the H5N1 virus in a laboratory setting can trigger clinical signs of disease similar to those of naturally infected animals on.....»»
Biologists discover human-infecting parasite produces sterile soldiers like ants and termites
New research from scientists at UC San Diego's Scripps Institution of Oceanography finds a tiny freshwater parasite known to cause health problems in humans defends its colonies with a class of soldiers that cannot reproduce......»»
Lethal bird flu could decimate Oceania"s birds—from vigilance to vaccines, here"s what Australia is doing to prepare
Avian influenza viruses have infected the world's birds for millennia. We first became aware of them in the 19th century, when mass deaths of poultry triggered interest in what was then called "fowl plague.".....»»
Of ants and trees: "Evolutionary déjà vu" in the tropical rainforest
Ants are famous for their regimented and complex social behaviors. In the tropics, they are also famous for forming mutualisms with plants. Certain species of trees have conspicuous hollow swellings that house ants, often feeding the ants with specia.....»»
Lice cause significant harm to cage-free poultry, study finds
Lice have been found feeding on the skin and blood of free-range chickens, which are infected at much higher rates than caged flocks. This finding could have implications for states like California, where all egg production is cage-free......»»
Study shows ancient viruses fuel modern-day cancers
Peek inside the human genome and, among the 20,000 or so genes that serve as building blocks of life, you'll also find flecks of DNA left behind by viruses that infected primate ancestors tens of millions of years ago......»»
Five people infected as bird flu appears to go from cows to chickens to humans
High temperatures made it hard for workers to use protective gear during culling. Enlarge (credit: Getty | Edwin Remsberg) The highly pathogenic avian influenza H5N1 virus that spilled from wild birds into US dairy cows.....»»
Engineered nanovesicles from activated neutrophils show promise in treating infected wounds
Infectious wounds represent a critical challenge in health care, especially for diabetic patients grappling with ineffective antibiotics and escalating drug resistance. Conventional therapies often inadequately address deep tissue infections, highlig.....»»
Advanced nanofibrous membranes can tackle diabetic wounds with precision
Diabetic wounds are notoriously challenging to treat, due to prolonged inflammation and a high risk of infection. Traditional treatments generally offer only passive protection and fail to dynamically interact with the wound environment......»»
Japanese honeybees slap nest-invading ants with their wings to knock them away
A trio of environmental specialists at the National Institute for Environmental Studies, in Japan, has found that Japanese honeybees sometimes resort to slapping ants with their wings to prevent their entry into their nest......»»
Asexual reproduction usually leads to a lack of genetic diversity. Not for these ants
Genetic diversity is essential to the survival of a species. It's easy enough to maintain if a species reproduces sexually; an egg and a sperm combine genetic material from two creatures into one, forming a genomically robust offspring with two disti.....»»
DNA tests confirm shark that bit California swimmer was juvenile white shark
A shark that bit a swimmer in Del Mar last month, leaving the man hospitalized with significant wounds, was a juvenile white shark, likely around 9 feet long and 6 to 8 years old......»»
Social contagion research explores how ant colonies regulate group behaviors
In the world of social creatures, from humans to ants, the spread of behaviors through a group—known as social contagion—is a well-documented phenomenon. This process, driven by social imitation and pressure, causes individuals to adopt behaviors.....»»
Can a new soundbar fix Sonos’ self-inflicted wounds?
Sonos may soon release an follow up to the popular Sonos Arc, but will it be enough to revive the company's battered reputation?.....»»
Features of H5N1 influenza viruses in dairy cows may facilitate infection, transmission in mammals
A series of experiments with highly pathogenic H5N1 avian influenza (HPAI H5N1) viruses circulating in infected U.S. dairy cattle found that viruses derived from lactating dairy cattle induced severe disease in mice and ferrets when administered via.....»»
Study reveals how stress pathways activate a cell"s emergency response procedures
Mayday! SOS! Distress signals like these are used around the world to indicate an emergency. The cells that make up your body also have their own versions of emergency signals. These get activated if a cell is infected by a virus or bacteria, or if t.....»»
A closer look at cell toxins: Researchers examine how radionuclides interact with kidney cells
When radionuclides enter our organism, whether by inhalation, ingestion, or through wounds, they pose a potential health risk. Many previous studies on radionuclide exposure have focused mainly on animal experiments. However, we have little data on t.....»»
NordVPN File Checker protects users from infected files
NordVPN launches its third experimental product from the NordLabs platform. File Checker is an online tool that scans different types of files for malware and viruses. It helps to prevent malicious codes invading user’s devices through infected or.....»»
Call the ant doctor: Amputation gives injured ants a leg up on infections
