Tracing unique cells with mathematics Posted: 23 Jan 2014 04:56 AM PST Stem cells can turn into heart cells, skin cells can mutate to cancer cells; even cells of the same tissue type exhibit small heterogeneities. Scientists use single-cell analyses to investigate these heterogeneities. But the method is still laborious and considerable inaccuracies conceal smaller effects. Scientists have now found a way to simplify and improve the analysis by mathematical methods. |
Carbon dioxide paves the way to unique nanomaterials Posted: 23 Jan 2014 04:56 AM PST In common perception, carbon dioxide is just a greenhouse gas, one of the major environmental problems of mankind. For Warsaw chemists CO2 became, however, something else: a key element of reactions allowing for creation of nanomaterials with unprecedented properties. |
Molecules as circuits? Miniaturization of electronic devices Posted: 23 Jan 2014 04:55 AM PST Silicon-based electronics has certain limits, in the physical sense of the word: this type of circuit can never become "nano" because of the physical laws governing the flow of electrons. This imposes a halt to the process of miniaturization of electronic devices. One of the possible solutions is to use molecules as circuits, but their poor conduction capabilities make them unlikely candidates. There is, however, a possible way around this, which was investigated in a recent article. |

Computer simulation of blood vessel growth Posted: 22 Jan 2014 05:20 PM PST Bioengineers showed that tiny blood vessels grow better in the laboratory if the tissue surrounding them is less dense. Then the researchers created a computer simulation to predict such growth accurately – an early step toward treatments to provide blood supply to tissues damaged by diabetes and heart attacks and to skin grafts and implanted ligaments and tendons. |
Athletes' performance declines following contract years Posted: 22 Jan 2014 02:06 PM PST A professor has determined that the contract year performance boost is real, but they caution team managers and coaches that it might be followed by a post-contract performance crash -- a two-year pattern they call the "contract year syndrome." |
Image or reality? Leaf research needs photos, lab analysis Posted: 22 Jan 2014 12:39 PM PST Every picture tells a story, but the story digital photos tell about how forests respond to climate change could be incomplete, according to new research. A new study shows that the peak in forest greenness as captured by digital pictures does not necessarily correspond to direct measures of peak chlorophyll content in leaves, which is an indicator of photosynthesis. The research has significant implications for how scientists use digital photos to study forest canopies. |
White, green or black roofs? Report compares economic payoffs Posted: 22 Jan 2014 10:44 AM PST Looking strictly at the economic costs and benefits of three different roof types -- black, white and "green" (or vegetated) -- researchers have found in a new study that white roofs are the most cost-effective over a 50-year time span. While the high installation cost of green roofs sets them back in economic terms, their environmental and amenity benefits may at least partially mitigate their financial burden. |
Live feed device monitors drugs in bloodstream in real time Posted: 22 Jan 2014 10:43 AM PST A device that can monitor the levels of specific drugs as they flow through the bloodstream may soon take the guesswork out of drug dosing and allow physicians to tailor prescriptions to their patients' specific biology. The biosensor combines engineering and biochemistry and has far-reaching potential. |
Researcher finds anonymity makes a difference with online comments Posted: 22 Jan 2014 10:43 AM PST In a newly published study, a researcher outlines a significant correlation between anonymity and civility. |
'Space cops' help control traffic in space Posted: 22 Jan 2014 10:42 AM PST Scientists are using mini-satellites that work as "space cops" to help control traffic in space. |
Toward fixing damaged hearts through tissue engineering Posted: 22 Jan 2014 10:41 AM PST In the US, someone suffers a heart attack every 34 seconds -- their heart is starved of oxygen and suffers irreparable damage. Engineering new heart tissue in the laboratory that could eventually be implanted into patients could help, and scientists are reporting a promising approach tested with rat cells. |
Laser scientists create portable sensor for nitrous oxide, methane Posted: 22 Jan 2014 10:41 AM PST Scientists have created a highly sensitive portable sensor to test the air for the most damaging greenhouse gases. |

Posted: 22 Jan 2014 06:24 AM PST Innovative electrodes allow new computer memory technologies to be compatible with existing circuitry. The computing industry faces constant demands to provide faster access to data and reduce power consumption. As current memory systems cannot meet these demands indefinitely, it is essential to develop entirely new technologies. One strong contender is resistive random access memory (RRAM), which stores binary information by switching a dielectric material between conducting and non-conducting states. |
Engineer converts yeast cells into 'sweet crude' biofuel Posted: 22 Jan 2014 06:19 AM PST A chemical engineer has developed a new source of renewable energy -- a yeast cell-based platform for producing biodiesel, which he has dubbed "sweet crude." The key to this platform is regular table sugar. It has the potential for industry scalability without the environmental costs of other biofuels. |
Faster testing of new pharmaceuticals Posted: 22 Jan 2014 06:16 AM PST To improve medical treatment, researchers test new drug ingredients on biological cells. By combining two microscopy techniques, the time required for testing can be reduced by 50 to 80 percent, and far fewer measurements are needed. |
New web-based course to prevent excessive weight gain may improve health in young adults Posted: 22 Jan 2014 06:14 AM PST The transition from adolescence to adulthood presents individuals with many challenges. Perhaps none are as important as those relating to health and quality of life. Being mildly to moderately overweight during this period substantially increases the likelihood of obesity at age 35 to 37. To prevent weight gain and promote healthy decision making, researchers developed a tailored, theory-based, web-delivered course to prevent excessive weight gain in young adults. |
