a detailed study of the man who did all of the above holds the answer. Forget Resveratrol, Tannins Key to Heart Health from Wine argues that wine's beneficial effects on heart health depend more on the traditional vintner's art than on the wonder molecule resveratrol. Either way, a little knowledge about the chemistry of wine can't hurt.read the full account of how researchers obtained this sequence data. Earth-like dunes on Titan. the old saw about humans and chimps sharing 98% of their DNA just isn't so--it's more like 94%.
Firm Develops Revolutionary New Method for Generating Human Embryonic Stem Cells without Harming EmbryosUnfortunately, the firm appears to have made claims that its research doesn't quite support--an event that said as much about hype surrounding new discoveries (and the way they're disseminated) as it said about stem cell research.
soliciting reader feedback in advance of the appearance of a feature story on Lucy's baby in the pages of Scientific American. Our online coverage included a Q&A with the enterprising fossil hunter who found this 3.3-million-year-old girl, as well as a multimedia presentation of the fossils themselves. 50 new species scientists unearthed in Borneo, but what about the new monkey genus (the first in 83 years), the 52 new species of fish, shrimp and coral that showed up in a survey of the seas of New Guinea, the new piranha discovered, along with 12 other new species of fish, in Venezuela, or the Kha-Nyou, a "living fossil" that is a member of a family thought to be extinct for the past 11 million years?regional fishing stocks have collapsed before, so what's to stop global fishing stocks from doing the same? water flowed across the surface of Mars in the past, but scientists were shocked to discover that liquid water exists on Mars today. Whether or not that means life has ever existed on Mars is still up for debate--but if Mars's oceans were as acidic as scientists currently believe, all signs point to no. extremophiles were also discovered in an ultraheated environment as acidic as vinegar, caught in the act of repairing chromosomes after massive doses of radiation, and found use as models of extraterrestrial life for NASA. whether or not dark matter actually exists, but the collision of two clusters--known as the Bullet cluster--revealed the existence of the mythical stuff via a measure of its gravitational lensing.
Six Volunteers in Serious Condition after Receiving a Trial Antibody from Pharmaceutical Company TeGeneroThe attempt to test a "superantibody" on human volunteers highlighted the pitfalls of human testing, even after extensive animal tests. debated for years whether hormone therapy would have a measurable effect on rates of breast cancer--if this finding holds, we can consider that debate settled. metamaterials, and only works in the microwave range of the electromagnetic spectrum.it had to be dropped from the periodic table in 2002 on account of its not existing, but now it's back, and this time for good. (Also worth checking out: How do scientists detect new elements, such as element-118, if they only last milliseconds before disintegrating?)
