March 27, 2024, 12:55:24 pm Mark says: Shocked Shocked Shocked Shocked  When Hamas spokesman Abu Ubaida began a speech marking the 100th day of the war in Gaza, one confounding yet eye-opening proclamation escaped the headlines. Listing the motives for the Palestinian militant group's Oct. 7 massacre in Israel, he accused Jews of "bringing red cows" to the Holy Land.

September 24, 2017, 10:45:16 pm Psalm 51:17 says: The specific rule pertaining to the national anthem is found on pages A62-63 of the league rulebook. It states: “The National Anthem must be played prior to every NFL game, and all players must be on the sideline for the National Anthem. “During the National Anthem, players on the field and bench area should stand at attention, face the flag, hold helmets in their left hand, and refrain from talking. The home team should ensure that the American flag is in good condition. It should be pointed out to players and coaches that we continue to be judged by the public in this area of respect for the flag and our country. Failure to be on the field by the start of the National Anthem may result in discipline, such as fines, suspensions, and/or the forfeiture of draft choice(s) for violations of the above, including first offenses.”
September 20, 2017, 04:32:32 am Christian40 says: "The most popular Hepatitis B vaccine is nothing short of a witch’s brew including aluminum, formaldehyde, yeast, amino acids, and soy. Aluminum is a known neurotoxin that destroys cellular metabolism and function. Hundreds of studies link to the ravaging effects of aluminum. The other proteins and formaldehyde serve to activate the immune system and open up the blood-brain barrier. This is NOT a good thing."

Be ye not deceived...our blessed hope is eternal life with our Lord and Saviour Jesus Christ IN HEAVEN!

1Co 15:50  Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; neither doth corruption inherit incorruption.
1Co 15:51  Behold, I shew you a mystery; We shall not all sleep, but we shall all be changed,
1Co 15:52  In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.
1Co 15:53  For this corruptible must put on incorruption, and this mortal must put on immortality.
1Co 15:54  So when this corruptible shall have put on incorruption, and this mortal shall have put on immortality, then shall be brought to pass the saying that is written, Death is swallowed up in victory.

Australian scientists said Thursday they had successfully implanted a "world first" bionic eye prototype, describing it as a major breakthrough for the visually impaired.
 Bionic Vision Australia (BVA), a government-funded science consortium, said it had surgically installed an "early prototype" robotic eye in a woman with hereditary sight loss caused by degenerative retinitis pigmentosa.
 
Described as a "pre-bionic eye", the tiny device is attached to Dianne Ashworth's retina and contains 24 electrodes which send electrical impulses to stimulate her eye's nerve cells.
 
Researchers switched on the device in their laboratory last month after Ashworth had fully recovered from surgery and she said it was an incredible experience.
 
"I didn't know what to expect, but all of a sudden, I could see a little flash -- it was amazing," she said in a statement.
 
"Every time there was stimulation there was a different shape that appeared in front of my eye.
 
Penny Allen, the surgeon who implanted the device, described it as a "world first".
 
Ashworth's device only works when it is connected inside the lab and BVA chairman David Penington said it would be used to explore how images were "built" by the brain and eye.
 
Feedback from the device will be fed into a "vision processor" allowing doctors to determine exactly what Ashworth sees when her retina is subjected to various levels of stimulation.
 
"The team is looking for consistency of shapes, brightness, size and location of flashes to determine how the brain interprets this information," explained Rob Shepherd, director of the Bionics Institute which was also involved in the breakthrough.
 
The team is working towards a "wide-view" 98-electrode device that will provide users with the ability to perceive large objects such as buildings and cars, and a "high-acuity" 1,024-electrode device.
 
Patients with the high-acuity device are expected to be able to recognise faces and read large print, and BVA said it would be suitable for people with retinitis pigmentosa and age-related macular degeneration.
 
Penington said the early results from Ashworth had "fulfilled our best expectations, giving us confidence that with further development we can achieve useful vision".
 
"The next big step will be when we commence implants of the full devices," he said.
