We've always suspected it, but now scientists have confirmed that dog owners are more likely to have better cardiovascular health.

The research was published in the journal Mayo Clinic Proceedings and involved 1,769 people between 25 to 64-years-old, living in Brno in the Czech Republic.

Each participant had to provide information on their BMI, diet, physical activity levels, cholesterol, blood pressure, if they smoked or not and their fasting blood sugar levels.

42 percent of the candidates owned a pet of some sort, with 24 percent of people owning a dog and 17.9 percent owning another animal.

The American Heart Association heart score system test was used, looking at seven changeable risk factors of heart health.

Dog owners were more likely to exercise, have an ideal diet and blood glucose level than those who didn't, but they were more likely to smoke for some reason. They still scored better overall for cardiovascular health, however.

The study authors cautioned: "The higher smoking rates among dog ownership attenuates the association between dog ownership and cardiovascular health."

Existing evidence links dog ownership to better mental and physical health, so it makes total sense.

Study co-author Andrea Maugeri commented in a statement: "In general, people who owned any pet were more likely to report more physical activity, better diet and blood sugar at ideal level.

"The greatest benefits from having a pet were for those who owned a dog, independent of their age, sex and education level."

Research claims that getting a pooch could be a useful way to boost heart health, and an important way to tackle the prevalence of heart disease.

Cardiovascular disease is the leading cause of death in the US alone, causing one-in-four deaths each year according to the Centers for Disease Control and Prevention.

Senior investigator Francisco Lopez-Jimenez stated that owning dogs has previously been linked to better mental health and feeling less lonely, both of which are assumed to decrease the risk of heart attacks.

One study published in the journal BMC Psychiatry, which examined 17 existing papers concluded having a pet could help the symptoms of mental illness.

Philippa Hobson, senior cardiac nurse for the British Heart Foundation, told Newsweek: "Whether you're a pet-owner or not, physical activity can benefit your heart in lots of different ways.

"Just spending 10 minutes a day walking around the block is good for your heart health," she added,

Who could ever deny that having a pup is good for us?

Researchers have identified a new species of pocket shark from the Gulf of Mexico, which uses it’s pouches to squirt a fluorescent fluid to conceal it from prey or predators.

The tiny shark found almost 10 years ago has turned out to be a new species, and we don’t know what to think of it. Is it cute, is it terrifying?

The American pocket shark is named after the pouches it has near it’s front fins rather than it’s diminutive size, and was collected during a survey to find out what sperm whales eat nearly a decade ago.

The mysterious pouches squirt little glowing clouds into the ocean, according to scientists studying the creature.

The details of the latest species are described in the journal Zootaxa by Mark Grace of the NMFS Mississippi Laboratories of the National Oceanic and Atmospheric Administration (NOAA) and Henry Bart and Michael Doosey of the Tulane University Biodiversity Research.

On the discovery, Grace said: “I’ve been in science about 40 years and I can usually make a pretty good guess about a marine animal’s identity. I couldn’t with this one.”

Grace then turned to experts at Tulane University and the American Museum of Natural History in New York, and the Florida Museum of Natural History at the University of Florida.

A 2015 paper identified the shark as only the second of it’s kind, but it took four more years of analysing the creature to make sure that it was a brand new species.

“The fact that only one pocket shark has ever been reported from the Gulf of Mexico, and that it is a new species, underscores how little we know about the Gulf – especially its deeper waters – and how many additional new species from these waters await discovery,” Henry Bart said.

Identifying the shark involved examining and photographing external features with a dissecting microscope, studying x-ray images and high resolution CT scans.

Somehow we don’t think it’ll be this cute, despite the name:

In an incredible breakthrough for cancer research, a female scientist from the National Polytechnic Institute (IPN) has reportedly found a complete cure for human papillomavirus (HPV).

The apparent cure would help to prevent the spread of cervical cancer among women. Dr Eva Ramon Gallegos, a Mexican scientist, claims to have eliminated the virus in 29 patients infected with HPV.

The report states that a team of researchers, led by Dr. Gallegos, treated the 29 women with non-invasive photodynamic therapy (PDT), which involves using a drug called a photosensitizer and a particular type of light to treat different areas of the body.

Dr. Gallegos had been studying the effects of photodynamic therapy for an amazing 20 YEARS to help tackle tumours such as breast and melanoma cancer, and specialised in the study of photodynamic therapy.

She treated 420 patients in Oaxaca and Veracruz, as well as 29 women in Mexico, with the technique. The repercussions from the treatment were promising; photodynamic therapy was able to eradicate the virus in all patients.

The virus was eradicated in 100 percent of those tested who carried HPV without premalignant lesions of cervical cancer using photodynamic therapy. The treatment was 64.3 percent successful in women with both HPV and lesions.

The therapy has no side effects, which is amazing as it doesn't do any damage at all to the body to have the treatment.

Dr. Gallegos said; “Unlike other treatments, it only eliminates damaged cells and does not affect healthy structures. Therefore, it has great potential to decrease the death rate from cervical cancer,” Radio Guama report.

HPV is a widespread virus from all over the world, with more than 100 variants. 14 of these variants can cause cervical cancer, a disease which is fast becoming a leading cause for death among female cancer patients.

Cervical cancer is the fourth most common cancer in women, according to the World Health Organisation (WHO).
