  We're gonna need a bigger boat! Two fisherman film an incredible encounter with a monster great white shark off the coast of Australia A pair of Western Australian fisherman managed to film their incredible encounter with a monster great white shark during a recent fishing trip.Perth angler Lee Ferguson and his friend Ryan Thornton had been fishing off the coast of Pinnaroo Point on Sunday morning.

A microbiologist explains the dangers of a dirty water bottle and compared the bacteria accumulation to that of barnacles on a boat - but gives the proper way to These are known to cause strep and staph infections. It is suggested to clean it hot, soapy water and a bottle brush at least every week .

A microbiologist has warned that your water bottle may be a portable Petri dish if it is not cleaned properly.

The bacteria accumulation is being compared to ‘barnacles on a boat’ and the most dangerous ones come from the outside world, which can cause strep and staph infections.

To transform the infected vessel back to a healthy water bottle, it is suggested that you clean every inch with hot, soapy water and a bottle brush, and do so at least once a week.

How To Actually Wash Germs Off Your Hands

  How To Actually Wash Germs Off Your Hands Hand washing is an essential and important part of not getting sick, or making others sick. Our skin is pretty good at keeping germs out, but the bacteria and viruses that cause colds, flu and diarrheal illnesses can ride around on our hands waiting for an opportunity to infect someone. Whenever you touch your hands to someone’s bodily fluids (or just a random surface that someone may have sneezed on), you can pick up those germs. And then when you touch your eyes, mouth, or nose — or eat finger food, which is basically the same as touching your mouth — you can possibly transmit those germs in a way that makes you more likely to get sick.

After working with many, many petri dishes of germs, Dantas and his group were left with four types of bacteria that They now looked at the genes — cellular instructions — within these bacteria . They also looked at It might seem like bad news that soil microbes can eat the drugs designed to kill them .

We know that bacteria can become resistant to antibiotics, but we've never seen it happen. In the time-lapse video, a white bacterial colony creeps across an enormous black petri dish plated with Then the bacteria start to edge their way into the toxic soup. More dots appear and they start growing

Dr. Philip Tierno, clinical professor of pathology and microbiology at NYU Langone Medical Center, told Mashable that 'it's imperative to scrub the inside of the bottle, too. Merely rinsing is not going to do the trick'.

'Bacteria tend to form a biofilm on the inside of the reusable container over time,' he said in the interview.

Taiwan bridge collapse crushes fishing boats, some crew feared trapped

  Taiwan bridge collapse crushes fishing boats, some crew feared trapped A bridge collapsed into a harbor in northeastern Taiwan on Tuesday, crushing several fishing boats with some crew feared trapped, authorities said. At least nine people fell in the water and seven were rescued, Taiwan's Central News Agency said. Six people were seriously injured, it reported.Divers were searching for those feared trapped in a couple of fishing boats, two government officials from the port township of Suao told Reuters."The bridge collapsed at around 9:30 a.m. while an oil tanker vehicle was on it, setting the vehicle on fire," said Shih I-chun, the secretary of the town's mayor.

'So you need mechanical action to get rid of that biofilm that coats the inside of the bottle.'

He continued to explain to Chloe Bryan with Mashable that the bacteria accumulation is similar to on a boat, or the soap grime that builds up on a bathtub.

Data has shown that humans buy a million plastic bottles around the world ever minute and 91 percent of them are not recycled.

So the shift from the twist top bottle to a reusable one could help reduce wasted, but if you are not cleaning it properly, it may increase your risk of infection.

In a creative stroke inspired by Hollywood wizardry, scientists from the Kishony Lab at HMS and Technion (www.technion.ac.il/en/) have designed a simple way to observe how bacteria move as they become impervious to drugs.

To clean bottle and vials, first freeze them to kill any flies in them . Another way to keep flies chilled is adding water to zip-lock type freezer bags, place in the freezer with a petri dish nestled on the Females remain virgins for only 8-10 hours after eclosure and must be collected within this time frame.

Some just shared a friendly reminder to the masses to wash their water bottle.

While another Twitter user shared that they actually found black mold lurking inside - but many do not think about what is lurking on the outside of their bottle.

Tierno told Mashable that it is the outside bacteria that is the most concerning.

'Some people may [for example] carry strains of staph that other people don't have. They may pick those up shaking hands with somebody, touching things like countertops, doorknobs, elevator buttons, telephones, computer keyboards,' he said.

'You're constantly exchanging flora on your hands, and then you're touching your water bottle.'

'You're unscrewing it, capping it, scraping lipstick from the mouthpiece — basically, you're ensuring that whatever was on your hands is getting into that water.'

A recent study looked at just how much bacteria was actually lingering in and around our water bottles.

The team swabbed 12 different bottles and found there were more than 300,000 colony-forming units (CFU) per square centimeter.

The lab looked at the four most popular bottles and found that the one with a slide-top hosted over 900,000 CFU where your lips touch.

However, all is not lost, as all you need to do is washing the bottle and do it properly.

Simply clean the bottle with hot, soapy water and use a bottle brush.

Experts have also suggested running it through the dishwasher after every couple of uses and replacing it often or soaking it in a large bowl of hot water with soapy and vinegar.
