Rats Given 20 Beers in Two Hours, But Recovered Their Balance in 15 Minutes

A chemical from an ancient herbal remedy makes rats almost immune to the effects of alcohol. Rats who've consumed the drug can consume vast quantities of alcohol without passing out, show few signs of a hangover - and don't become alcoholics, even after weeks of solid drinking, say researchers. The chemical is extracted from an ancient Asian remedy - a seed first used as a hangover cure in the year 659. Rats respond to alcohol in a very similar way to humans. The UCLA researchers now aim to find out if the compound will work in humans.

The Asian seeds - from the tree Hovenia Dulcis - was first used as a hangover cure in the year 659, according to Science Daily. The researchers began their study by looking at herbal compounds that supposedly had 'anti alcohol' effects. They rapidly homed in on the Asian seed. They tested one ingredient - called DHM or dihydromyricetin in the rats.

The rats were given the equivalent of 15 to 20 bottled beers in two hours. Most animals passed out, and remained motionless when flipped over. When given DHM, the rats could 'handle' their drink better. They took longer to get drunk, and seemed to sober up in about 15 minutes. The compound seemed to help rats dealing with hangover anxiety, too. Rats recovering from a binge seemed to perk up when given the compound. Perhaps most importantly for medical professionals, the chemical seems to stop rats wanting to drink. Although rats on DHM can drink more, they don't. 'When you drink alcohol with DHM, you never become addicted,' says the lead researcher, Jing Liang in research published in Journal of Neuroscience. The drug appears to work by blocking a brain receptor. Other promising anti-alcohol drugs have targeted the same receptor - but also caused seizures.

What do you see??? To the untrained eye you see nothing but to me I see something that 99.9% of the population would overlook. It’s a decaying rat carcass in leaf/grass debris. I am on a property doing a termite inspection and I look around the surrounding area and find this dead rat about 25FT from the building.

I investigate further and find several rat burrows nearby and alerted the property manager who was thrilled I took the extra effort to uncover this. As a result we were able to nip this potential situation in the bud and protect our client.

Sherlock Holmes = You must train yourself to observe what others overlook.

Mice need dark warm areas to create nests (harborage). They absolutely love to get inside air filters, engines, etc. No matter if it is your lawnmower, motorcycle, or car they will find it. The two pictures attached to this show you how amazingly fast they are at setting up shop in these areas. This is my car and it was in my driveway for JUST ONE NIGHT and I opened the hood the next morning to add washer fluid and found this damage!

As you can see they tore the felt hood + battery cover up to make a nest. This is a VERY SERIOUS & DANGEROUS issue because they can cause the vehicle to malfunction at any point. It can lead to a crash or fire at any time. It is virtually impossible to repel or rodent proof these things from rodents as there are over 100 entry points for a mouse to get into a car engine. Call EHS as we do have some creative solutions for issues like this.

Rats Infesting Food Store Prompt Inspector Visit

A cellphone video of rats taken by a passerby at a Vancouver grocery store has prompted a visit to the business by Vancouver health inspectors.

Matt Johnson was walking along West Broadway Saturday when he looked through the window at Kitsilano Natural Foods and saw large rats crawling over food and knocking over containers inside.

Johnson said he was with a female friend who started screaming at the sight.

“There were rats all over the place," he said.

Johnson pulled out his phone and started recording because he thought people wouldn’t believe it when he told them about the bizarre scene without visual proof.

"They were going through the produce, they were running up and down the walls. They had knocked down cans of stuff. It was a big mess.”

Health inspectors were notified about the video, inspected the store Tuesday, and have spoken with the owner about dealing with its rodent problem.

The rodents are a common problem in Vancouver, but if an infestation becomes too severe, inspectors can shut that business down, according to Trudi Beutel, of Vancouver Coastal Health.

"There has to be a wholesale infestation,” Beutel said. “And we have to believe there has been no due diligence on the part of the owner to correct any of the issues that have been brought to light over the course of the investigation."

The owner of Kitsilano Natural Foods, Ben Huinh, said Thursday that pest control technicians were sealing his building and getting rid of the rats.

Huinh said customers shouldn't be worried.

“Our policy for our goods is when in doubt, throw it out. So if we see anything that appears to be tampered with by rodents or anything we will discard of it," said Huinh.

Fall is the time of year that rats become more of a problem, as they seek warm places to go and food to eat, so they can be hard to keep out of homes and businesses, said Peter Steinfort, of Care Pest Control.

"They are excellent climbers, so they can go in through soffits. They can go through any sort of opening,” said Steinfort. “All a rat needs is about half an inch and that's enough for them to squeeze through.”

Steinfort said home and business owners need comprehensive plans to deal with the problem.

Housing Worker Kills Monster, 3ft Rat .... and Says There Are More

A huge rat has been speared to death by a pitchfork at a sprawling New York housing project.

Jose Rivera, a Housing Authority worker, was clearing a rat hole at the Marcy Houses in Brooklyn when three of the creatures popped out.

He was only able to nab one. It appears to be almost three feet long, including the tail, is covered in white fur and looks well-fed.

Mr Rivera, 48, said: 'I hit it one time and it was still moving.

'I hit it another time and that's when it died. I'm not scared of rats but I was scared of being bitten.'

Naomi Colon, head of the Marcy Houses Tenant Association, said there have been sightings of the outsize rat for at least six years.

She said: 'The residents have told me that they've seen it running around with other rats.

'She lived with them. She ran into the same hole they ran in.'

Animal experts have identified the monster rodent as a Gambian pouched rat, which is a fairly common pet rat.

They are nocturnal, can grow to three feet, weigh four pounds or more and live seven or eight years, the New York Daily News reports.

Imports have been banned since 2003, when the rats were blamed for a monkeypox outbreak that affected 100 people.

Dr Paul Calle, director of zoological health at the Wildlife Conservation Society, said the Marcy Houses specimen was probably an escaped or discarded pet who decided to join the regular rats.

He said: 'They are a very social animal and live in big groups in the wild.

'Our Norway rats are the closest big rodents it could accompany.'

He said they can be trained to sniff out landmines,adding that 'they're pretty remarkable animals'.

Tenants fear that the Gambian rat has been breeding with the Norway rats and spawning a super-breed of rodents.

But Mr Calle said the imported rat probably would not mate with local rats, and it couldn't reproduce if it did, because each is from a different genus.

One Marcy Houses resident, who declined to be named for fear of reprisals from city or property management, described the conditions there.

'In one day eight big size rats were killed,' he said, adding that they have been seen in the playground.

Another resident said: 'Adults had to grab children and run because a lot of rats came on the playground. The kids were screaming.'

Resident Stephanie Davis, 44, said: 'Even the cats are afraid of the rats. They get together and gang up on the cats.'

Pam Davis, 43, added: 'They're here day and night. We don't dodge bullets. We dodge rats. They're so big, they should charge them rent.'
