As pandemic-related restrictions ease and people return to parks and other outdoor spaces, remember to protect yourself against another threat -- ticks.

"With our latest mild winter, ticks have been active in much of the region on warmer days all winter long," said Jody Gangloff-Kaufmann, an entomologist at Cornell University in Ithaca, N.Y., who said it's too soon to predict populati...

The mystery of "stinging water" has been solved, scientists say.

Stinging water is the seawater near and around upside-down jellyfish (Cassiopea) -- and swimmers can get stinging, itchy skin while submerged in it, even if they have no direct contact with the creatures themselves.

But it wasn't clear in the past if the jellyfish were to blame for this discomfort, since...

Lab-altered mosquitoes have made a big dent in the spread of dengue fever, researchers report.

How? Australian scientists released mosquitoes carrying a bacteria that prevents transmission of the dengue virus.

The strategy resulted in a 76% decrease in dengue transmission in a community in Indonesia that has frequent dengue outbreaks. Similar reductions were seen in an u...

A global coalition of more than 11,000 scientists warns that planet Earth is facing a "climate emergency" that will cause "untold human suffering" unless drastic steps are taken.

The warming climate is already taking a toll on human health, causing widespread hunger and illness that will grow exponentially worse, said the warning's lead author, William Ripple. He's a professor of ecol...

Some mosquitoes spread diseases to humans through their bite, passing along harmful pathogens like Zika, dengue fever, West Nile virus and chikungunya.

Now humans are turning the tables, infecting these dangerous mosquitoes with bacteria that sabotage their ability to spawn.

Chinese researchers were able to reduce these mosquito populations by as much as 94% using a bact...

Although unwelcome, insect stings pose a serious risk threat to only a small percentage of people, a medical expert says.

"While millions of people suffer insect stings, true allergic reactions occur in a mere 0.4 to 0.8% of children and up to 3% of adults," said Dr. Morissa Ladinsky. She is an associate professor of pediatrics and adolescent medicine at the University of Alab...

Summer is synonymous with mosquitoes, and that means possible exposure to the West Nile and Zika viruses. Both are spread mainly through mosquito bites.

Most people won't experience symptoms from either virus, but there are important differences to be aware of.

West Nile

  • Up to 20% of infected people have symptoms, such as a fever, headache, body ach...

Many flies and flying insects in hospitals carry bacteria that could pose an infection risk to patients, and more than half of them carry the types that resist antibiotics, a new study says.

British researchers used ultraviolet-light flytraps, electronic fly killers and sticky traps to collect nearly 20,000 flies, aphids, ants, wasps, bees and moths at seven hospitals in England over ...

No parent wants their child to suffer a dog bite, and new research offers some guidance on which dogs are the riskiest around young kids.

The body size and head shape of dogs affect the bite and injury risk they pose, the researchers found.

For the study, the investigators examined 15 years of visits for facial dog bites at two emergency departments, and more than 45 years o...

As deer populations have exploded across America, moving from forests to suburbs to urban parks, they have brought the threat of Lyme disease to millions of city dwellers, a new study finds.

In fact, the deer tick that spreads Lyme disease is as prevalent in many New York City parks as it is in areas known to be endemic for the bacterial disease, such as Connecticut and other states i...

It sounds like something out of a horror film: A blood-hungry insect feeds on its prey's faces while they sleep, leaving behind a parasite that can cause stroke and heart disease.

But the triatomine, or so-called "kissing bug," is all too real and found regularly in Latin America, but also has been found in several areas of the United States, as far north as Illinois and Delaware. An...

Strong currents and sharks aren't the only threat to saltwater swimmers in Australia. A deadly jellyfish often tops their list of threats.

But researchers working with mice have discovered a potential antidote to the lethal sting of the Australian box jellyfish -- the world's most venomous sea creature.

The treatment in question? A cholesterol drug.

Each box jellyf...

You now have an excuse to skip cutting the grass every weekend -- it's beneficial for the bees.

And mowing your lawn less often to provide native bees a better habitat won't lead to an increase in disease-carrying ticks, experts say.

When research ecologist Susannah Lerman began urging friends and colleagues to leave lawns a bit longer to help the bees, the "first thing peop...

Certain tick bites can cause a red meat allergy, and now scientists are shedding new light on the condition, known as alpha-gal syndrome.

Alpha-gal is a sugar found in most mammal blood, but not in humans.

"Our original hypothesis was that humans developed the allergy after being exposed to alpha-gal through a tick that had fed on a deer, dog or other small mammal that has ...

The bites of insects, spiders and dogs are a $1 billion yearly drain on the U.S. health care system, a new study has calculated.

And climate change is only going to make matters worse, researchers contend.

Attacks by mountain lions, bears and alligators get the most press, but the tiniest critters create the most work for emergency room doctors. B...

Americans have unwelcome eight-legged visitors from the East, and they're here to stay.

The Asian longhorned tick -- Haemaphysalis longicornis -- "is a tick indigenous to Asia, where it is an important vector of human and animal disease agents," warned a research team from the U.S. Centers for Disease Control and Prevention.

The tick species has already turned up in A...

If the thought of vampire bats sucking your blood for their meals isn't enough to scare you, new research shows they also carry dangerous bacteria that can cause a potentially deadly infection of the heart's inner lining and valves.

Researchers at Montana State University said they found Bartonella infection is common among these bats, posing a health risk to people and domest...

Malaria is transmitted by mosquitoes carrying malaria parasites, but scientists report they have discovered compounds that might keep mosquitoes from spreading the sometimes deadly disease.

"Current anti-malarial drugs can cure a person of the disease, but that person is still infectious to mosquitoes, and can therefore still cause someone else to become infected," explained lead rese...

The threat of rattlesnake bites in California decreases during droughts and increases after rainy weather, a new study finds.

Rainy spells result in more shrub growth and, with that, more rodents, the snakes' primary food source, said study author Dr. Grant Lipman, an emergency medicine physician at Stanford Medicine, and colleagues.

"More food, more snakes, more snakebites,...

A new class of natural-based mosquito repellents appears to be effective, researchers report.

Each year, nearly 700 million people worldwide contract mosquito-borne diseases, such as malaria, West Nile, Zika and dengue fever, resulting in more than 1 million deaths.

Many mosquito species have become resistant to commonly used pyrethroid-based insecticides, so an urgent searc...

Deer ticks are scary enough. Now, scientists have linked bites from the lone star tick to about one-third of all potentially life-threatening allergic reactions around Tennessee.

A lone star tick bite can cause a severe immune system response to red meat -- such as beef, pork and lamb -- said study lead author Dr. Debendra Pattanaik.

Lone star ticks, or amblyomma america...

As the tick population surges across the United States this summer, one doctor says the best way to avoid being infected with the nasty illnesses the tiny bugs carry is to wear protective clothing and to check your body thoroughly after every trip into the woods.

Just last week, a new study found that ticks have spread far and wide in recent years, and they are now being reported in a...

Where you live in the world may determine whether you'll survive a snakebite.

About 93 million people worldwide live in remote regions where there are venomous snakes. If bitten, these folks are at increased risk of death due to limited access to anti-venom drugs, researchers said.

"Understanding where venomous snakes live and people's proximity to effective treatments are t...

Think you live in a place that's free from disease-carrying ticks? Don't be so sure.
