Three workers hired to clean a putrid well at a waste transfer station died Monday when they apparently were overcome by toxic fumes, the fire department said.Initially one worker fell or climbed into a shaft that s part stanley romania of the well and the other two went in stanley bottle after him when he didn t return, said John Sudnik, fire department deputy assistant chief of the Queens borough command.The fire department now says two of the victims were a father and son -- 49-year-old Shlomo Dahan and 23-year-old Harel Dahan of Brooklyn, along with 52-year-old Rene Francisco Rivas of Queens. The medical examiner will determine what caused their deaths.Police say the father and son were cleaning the well in Queens on Monday when the son fell down a narrow shaft. The father grabbed a ladder and climbed down to rescue his son, followed by Rivas.The men were hired to cl stanley tumblers ean out a basin intended to catch water and waste from the transfer station, where garbage is sorted for recycling. The entrance to the basin is through a manhole 3 feet wide; the basin is 18 feet deep. The men likely were overcome by hydrogen sulfide, a toxic gas common in wells like the one to be cleaned Monday, Sudnik said. The gas is created by water and decomposing garbage. About 100 parts per million of the gas in the air is considered incredibly dangerous, and crews were getting readings at the scene of 200 parts per million, Sudnik said.Emergency crews got a call around 2:30 p.m. and were on the scene seven minutes later.

A terrifying feature of the deadly rabies viru stanley thermos mug s is how fast it moves along the body nervous system toward the brain, at speeds approaching half a meter per day. Its speed has been a medical mystery 鈥?but now researchers have a promising new lead that could explain how rabies spreads. Above: An electron micrograph of the rabies virus, with virions appearing as dark-grey rods | Photo Credit: CDC/Dr. Fred Murphy Observations made by Tel Aviv University Shani Gluski suggest the rabies virus hijacks the central nervous system by means of a growth factor receptor named p75NTR. The describe their findings in detail in the latest issue ofPLOS Pathogens. p75NTR belongs to a family of receptors stanley cup that, in a healthy body, is responsible for binding neurological factors on the surface of neurons and ushering them inside the cell. There, they are packaged and carried swiftly along the length of the cell stanley cup in the direction of the cell body. This process is called retrograde axonal transport. Lots of pathogens exploit the retrograde axonal transport system to invade the central nervous system, including herpes, polio, and, of course, rabies. That p75NTR has been shown to transport neurological factors at a speed comparable to rabies ; spread made it an ideal target of investigation for Gluski team. PopSci Jason Tetro describes what happened next: In the lab, the researchers took neurological tissue from embryonic mice and placed them into small microflu
