Chemotherapy is extremely valuable in killing cancer cells but also takes surrounding tissue with it. Micro-scaled photovoltaic devices may one day be used to deliver chemotherapeutic drugs directly to tumors, rendering chemotherapy less toxic to surrounding tissue, according to findings presented at the AVS 57th International Symposium&Exhibition in Albuquerque.
I enjoy a good romp in the hay as much as the next space scientist, and I'd love to go to Mars, so it's nice to see that researchers are tackling both issues simultaneously. Further, there are few things as satisfying as a good review article. A review article is one that simply summarizes the current thinking and theories on a topic. In this case, the topic is Sex on Mars.
Israel’s national lottery is all over the news these days because the same numbers (13, 14, 26, 32, 33, and 36) came up
twice during one month.
A journalist called an expert on gambling, Z. Gilula, a professor of statistics in Israel, and asked him about the probability of the same set of numbers being randomly picked twice.
When a NASA rocket slammed into the Moon last fall, scientists knew they would get information about the composition of the lunar soil at the poles that has never been sampled.
The findings from that NASA mission, called LCROSS for Lunar CRater Observing and Sensing Satellite, are out, and they are interesting to say the least.
The emptied upper stage of a rocket crashed into the Cabeus crater near the Moon's south pole last October. A second spacecraft followed to analyze the ejected debris for signs of water and other constituents of the super-chilled lunar landscape.
A numerical model can't help you finish a marathon, that will take a lot of running, but math can at least help you be the most efficient your body can be.
The best part about the night before a marathon is 'carb'ing up' the night before with a healthy pasta dinner but marathoners in training long before that make many mistakes with their diet, assuming "I'm in training" means they can eat twice as much of anything.
A new study in rats says growing up with lots of sisters makes a male less sexy to females, because the sex ratio of a male rat's family while young influences his sexual behavior and therefore how female rats respond to him later.
Early life obviously affects later behavior but how early and how much of an impact and how can it be quantified in a less 'soft' fashion. There are correlation studies that even conclude the position of a fetus in the uterus matters and that a female fetus that spends the pregnancy sandwiched between two brothers grows up to be more masculine because she's been exposed to their hormones.
Lithium-ion batteries are commonly regarded as promising for the cars of the future (at least until hydrogen fuel cells are ready for prime time) but environmentalists interested in electric or hybrid vehicles are concerned about the acid rain caused by battery manufacturing and high replacement cost for the batteries, which will last about the same as a standard car battery but are a terrific expense.
Anthropomorphizing, the process, as Twain might say, of “underestimating the animal by assigning to him human traits,” has had a good year. The reasons range from the continuing dominance of the Obama dog, Bo, on Fox News (Bo: “Socialist or simple anarcho syndiclist?”), to the rise of kitty cat “jammers” for tabby sleepover night. Not kidding. On the sleepover thing.
Astronomers report they have measured the distance to the most remote galaxy and have found that they are seeing it when the Universe was only about 600 million years old (a redshift of 8.6), making those the first confirmed observations of a galaxy whose light is clearing the opaque hydrogen fog that filled the cosmos at this early time.
