Computer uses light to control ‘cyborg’ bacteria
A computer automatically controls the growth of new “cyborg” bacteria, report researchers. Two interfaces link machine and organism: the computer communicates with red and green light, which the...
View ArticleCell culture chip could replace some animal tests
A new cell culture method could let scientists forgo certain tests on animals in the future. A team led by scientists from the department of biosystems at ETH Zurich in Basel developed the cell culture...
View ArticleThickness of new coating changes its color
New materials with a network-like structure create a full spectrum of intense colors and highly scratchproof coating for metals. The lower layer of the designer material is a metallic network...
View ArticleWhy big data can’t predict the next armed conflict
The expectation that big data alone will be enough to predict armed conflict is unrealistic, according a recent Science essay coauthored by Lars-Erik Cederman, professor of international conflict...
View ArticleBirds don’t carry seeds far enough to save rainforest
In order to restore tropical rainforests, it is not enough to simply set up protected areas and leave them alone, research in an Indian rainforest shows. Leaving degraded and logged areas of tropical...
View ArticleMake ceramics with a press instead of a kiln
Making ceramic materials like cement, bricks, bathroom tile, and porcelain, normally requires lots of heat—kilns used to fire the materials get to temperatures well over 1800º F. A new method, by...
View ArticleLiquids in thin battery could cool stacks of computer chips
A newly designed “flow” battery could make it possible to stack computer chips like pancakes to save space and energy. The battery, only around 1.5 millimeters thick, uses two liquid electrolytes to...
View ArticleWatch 4D-printed object become a sturdy dome
A new construction principle makes it possible to print flat objects and to unfold them three-dimensionally later. 4D printing creates moveable and shape variable objects such as flat components that...
View ArticleTourist pics and YouTube create 3D model of city
A new technology platform uses algorithms to create 3D city models from image and video data. The platform, known as “VarCity”, is so versatile that it can use, evaluate, and automatically combine all...
View ArticleLittle daggers let bacteria live inside amoeba
New research reveals how a recently discovered bacterium survives—and thrives—inside predatory amoebae. Hungry amoebae hunt bacteria: they catch them with their pseudopodia and then absorb and digest...
View ArticleTeam discovers how bacterium runs on methanol from leaves
New research identifies the genes that a bacterium needs to live on methanol. The work could offer chemists clues to making small carbon molecules into larger ones–something bacteria learned long ago....
View ArticleBreath sensor tells you when you’re burning fat
Scientists have developed a breath sensor that can detect when the body is burning fat. Experts advise anyone looking to shed extra pounds to eat less and exercise more. One way is with endurance...
View ArticleHear the ‘minimalist’ way baby birds learn songs
Songbirds are minimalists when it comes to learning a new song, research shows. The birds’ learning strategy resembles the methods that computer scientists use for document comparison. For a songbird,...
View ArticleHow do brains drain? Not how textbooks say
Scientists have disproved a decades-old orthodoxy: Cerebrospinal fluid does not leave the cranial cavity via blood vessels, but instead through the lymphatic system. This finding has far-reaching...
View ArticleHow certain quantum dots shine so brightly
Researchers have found an explanation for why a certain class of quantum dots shines with such incredibly bright colors. The nanocrystals in question contain caesium lead halide compounds arranged in a...
