Dangerous Frogs of South America

Though South American animals have been named little is known about many of them. Scientists fell into the trap of taking frogs for granted. They got more than they bargained for.  Aparasphenodon brunoi and Corythomantis greeningi are the first venomous frogs to be identified. The dart frogs have bony spines on their faces that they jab into potential predators.
Venomous toxic frog corythomantis greeningi
Like snakes, the frogs inject a toxin into the body of threats. This is odd really, because the frogs have evolved this defence while having no natural enemies. The target of a frog was Edmund Brodie, a biologist, who suffered intense, radiating pain lasting for over five hours. He was lucky: a gram of this venom can kill 300,000 mice or 80 people. It would take many frogs, though, to make this much toxin.

The attack on the scientist was a glancing blow by C. greeningi, which is not as potent as A. brunoi. The team was not going to test out A. brunoi, however. Another thing was learned by the biologist: when you walk in the jungle don't go around picking things up. You may get a surprise!

Mysterious Death

The odd case of a woman who police claim stabbed herself to death with an 8 inch long knife - you would have to be a Japanese officer in dire straits to do this! For some reason police have always stuck to their suicide finding. A doctor working in a funeral parlor thought it was odd that the woman had wounds on her hands as if she was defending herself. It took two years before police got back to him after he reported this.
Dr Karen Mahlo
Police said that the victim, Dr Karen Mahlo, had stabbed herself as she lay on her back in bed. John Michael Hehir, her boyfriend, was not a suspect, then: his claims of not being able to phone her and rushing to her house had been verified. He said lights were turned off downstairs. Why would you turn the lights off if you were going upstairs to kill yourself?

A very strange thing was that the knife had been plunged through her pyjamas. One would have pushed the pyjamas aside to get it over with. Her death was well planned: a note was on a running computer with a copy on the desk and another addressed to her children telling then they were left nothing. Cases of such vigorous preparation are rare.

John Hehir behaved in a peculiar manner. During the drive to Mahlo's home on the night of her death he phoned for an ambulance before he reached the house. Soon after he returned, then took a bike and a USB drive. Hehir had a will in his possession which left him her house but not her investment properties. The "real" will was located on the computer leaving everything to her children and parents. Unfortunately, the computer will is not valid.

Justice Philip McMurdo dismissed the family's claim. There has never been an inquest into the death. It shows how stupid police and judges are in cases like this. John Michael Hehir has never been charged.

Hangover Cure - Pears

Apparently, Australia has found a cure for hangover. This does come from a reputable source - CSIRO. Symptoms of hangover are headache, dry mouth, nausea, sweating, sore stomach, and drowsiness. Just why we suffer is not known. No specific chemical has been isolated as causal.
Pear cider cures hangover
The "cure" seems to be too easy - you eat pears! This fruit has other benefits: it is anti-inflammatory, lowers cholesterol and relieves constipation. A variety grown in Korea attacks aldehyde dehydrogenase (ALDH) and alcohol deydrogenase (ADH) which are involved in metabolizing alcohol. Pears must be consumed before imbibing to have the curative effect. Whether it just stops alcohol from being absorbed is not yet known. It if it does this, then it would not be much use.

Alcohol depletes the body's vitamin and mineral resources. Time is needed to get the correct balance back. This means an instant "cure" will not be possible. Blocking alcohol is possible though. Pears may do this. You can eat pears and drink, or choose not to drink in the first place.
