    A stunning explosion of zinc fireworks occurs when a human egg is activated by a sperm enzyme, and the size of these "sparks" is a direct measure of the quality of the egg and its ability to develop into an embryo, according to new research from Northwestern Medicine. The discovery has potential to help doctors choose the best eggs to transfer during in vitro fertilization (IVF), the scientists said. This is the first time the zinc sparks have been documented in a human egg. "This means if you can look at the zinc spark at the time of fertilization, you...

    UCLA scientists inject silicon carbide nanoparticles into a magnesium zinc alloy. The result is a metal with 'record breaking' strength and stiffness-to-weight.Scientists at UCLA have found a new way to inject silicon carbide nanoparticles into a molten alloy of magnesium and zinc, resulting a metal nanocomposite that demonstrates "record levels" of stiffness-to-weight and specific strength, and "superior stability" at high temperatures. Magnesium is already the lightest structural metal, this lab creation maintains its light weight but makes it much stronger. The researchers said they also developed a scalable manufacturing process, opening up a door to lighter and stronger cars, planes,...

    US Ebola Death: Antivirals Submitted by admin on Wed, 10/08/2014 - 13:19 The first U.S. Ebola patient, Thomas Eric Duncan, has died despite being administered the experimental nucleoside-type antiviral pro-drug Brincidofovir.  How is this possible?  Well , the first problem is that Duncan was not treated until it was far too late for antiviral therapy to work.  Let's take this opportunity to look at some nucleoside antivirals, incuding the drug that was administered to Mr. Duncan in Dallas, TX (Brincidofovir).The first thing to know is remember Brincidofovir and Cidofovir were developed to work against dsDNA Viruses, though Ebola is a...

    Greenland's prime minister warned the European Union he could scrap a preliminary deal intended to safeguard the bloc's access to his country's huge mineral resources, saying Brussels has failed to follow through. "I don't understand the behavior of the (European) Commission," leftist Kuupik Kleist said on Wednesday in his office... Kleist's comments to Reuters signal Greenland may be increasingly willing to play off rival powers from Brussels to Beijing that are drawn by its minerals as global warming opens up sea routes and mining prospects. Kleist, who grew up harpooning whales from a remote village in northern Greenland, faces a...

    Scientists in Denmark have compared how organic and non-organic diets affect dietary mineral uptake in humans, focusing on copper and zinc. They found that there is no difference between the two diets when it comes to uptake and how the minerals are processed in the body.Copper and zinc are two essential trace elements with unknown availability in organic verses non-organic diets. Alicja Budek Mark and colleagues at the University of Denmark investigated the content of these elements in non-organic versus all-organic diets fed to 20 men over 12 days. And Mark’s team assessed the in vivo absorption of zinc and...

    A new study has outlined for the first time a biological mechanism by which zinc deficiency can develop with age, leading to a decline of the immune system and increased inflammation associated with many health problems, including cancer, heart disease, autoimmune disease and diabetes. The research was done by scientists in the Linus Pauling Institute at Oregon State University and the OSU College of Public Health and Human Sciences. It suggests that it's especially important for elderly people to get adequate dietary intake of zinc, since they may need more of it at this life stage when their ability to...

    Giving zinc as a supplement along with antibiotics can significantly reduce mortality by lowering treatment failure in children suffering from serious infections such as pneumonia and meningitis, according to a study. The study, reported in the latest issue of the international medical journal, The Lancet, has found that babies who were given zinc supplement were 40 per cent less likely to experience treatment failure and their risk of death was reduced by 43 per cent. The study covered 700 babies aged between seven and 120 days — 352 of them were given zinc supplement along with the standard antibiotics and...

    DURHAM, N.C. – Zinc has been found to play a critical role in regulating communication between cells in the brain, possibly governing the formation of memories and controlling the occurrence of epileptic seizures. A collaborative project between Duke University Medical Center researchers and chemists at the Massachusetts Institute of Technology has been able to watch zinc in action as it regulates communication between neurons in the hippocampus, where learning and memory processes occur – and where disrupted communication may contribute to epilepsy. "We discovered that zinc is essential to control the efficiency of communication between two critical populations of nerve...

    Explanation: Why does this Martian rock have so much zinc? Roughly the size and shape of a tilted coffee-table, this oddly flat, light-topped rock outcropping was chanced upon a few weeks ago by the robotic Opportunity rover currently rolling across Mars. Early last month Opportunity reached Endeavour crater, the largest surface feature it has ever encountered, and is now exploring Endeavour's rim for clues about how wet Mars was billions of years ago. Pictured above and named Tisdale 2, the unusual rock structure was probed by Opportunity last week and is now thought to be a remnant thrown off during...

    Zinc lozenges may shorten common cold duration Depending on the total dosage of zinc and the composition of lozenges, zinc lozenges may shorten the duration of common cold episodes by up to 40%, according to a study published in the Open Respiratory Medicine Journal. For treating the common cold, zinc lozenges are dissolved slowly in the mouth. Interest in zinc lozenges started in the early 1980s from the serendipitous observation that a cold of a young girl with leukemia rapidly disappeared when she dissolved a therapeutic zinc tablet in her mouth instead of swallowing it. Since then over a dozen...

    Taking zinc syrup, tablets or lozenges can lessen the severity and duration of the common cold, experts believe.A review of the available scientific evidence suggests taking zinc within a day of the onset of cold symptoms speeds recovery. It may also help ward off colds, say the authors of the Cochrane Systematic Review that included data from 15 trials involving 1,360 people. Now more work is needed to determine the exact dosing required, they say. Adults catch between two to four colds a year and children up to 10 a year. > There is no proven treatment for the common...

    Consumers should stop using Zicam Cold Remedy nasal gel and related products because they can permanently damage the sense of smell, federal health regulators said Tuesday. The over-the-counter products contain zinc, an ingredient scientists say may damage nerves in the nose needed for smell. The other products affected by the Food and Drug Administration's announcement are adult and kid-size Zicam Cold Remedy Nasal Swabs. The FDA says about 130 consumers have reported a loss of smell after using Matrixx Initiatives' Zicam products since 1999. Shares of the Scottsdale, Ariz.-based company plunged to a 52-week low after the FDA announcement, losing...

Al Gore has profited from zinc mining that has released millions of pounds of potentially toxic substances near his farmstead, but there is no evidence the mine has caused serious damage to the environment in the area or threatened the health of his neighbors. Two massive white mountains of leftover rock waste are evidence of three decades of mining that earned Gore more than $500,000 in royalty payments for the mineral rights to his property.

    PLYMOUTH, Mass. (July 2) - In this village settled by thrifty Pilgrims, you can still buy penny candy for a penny, but tourist Alan Ferguson doubts he'll be able to dig any 1-cent pieces out of his pockets. He rarely carries pennies because "they take up a lot of room for how much value they have." Instead, like so many other Americans, he dumps his pennies into a bucket back home in Sarasota, Fla. Pity the poor penny! It packs so little value that merry kids chuck pennies into the fountain near the candy store, just to watch them splash...

    Zinc may be good for teenagers' brains, according to a paper presented last week at a meeting of the American Society of Nutritional Sciences. In a study led by James Penland of the Agricultural Research Service of the Department of Agriculture, 209 seventh-graders were randomly assigned to one of three groups. The first group received 4 ounces of fruit juice a day containing 20 milligrams of zinc, the second drank the same juice with 10 milligrams of zinc, and the third drank the juice alone with no zinc added. At the beginning and end of the 12-week study, students were...
