6:26 AM | Gastronomía en el límite (III): Picante extremo
De nuevo comenzamos con un vídeo que nos sirve de introducción para esta nueva entrega de la serie sobre experiencias gastronómicas en el límite.Como acabáis de ver, el conocido chef Gordon Ramsay se va a la India y se atreve a probar un cachito de Bhut Jolokia, uno de los pimientos más picantes del mundo. Y lo hace en el marco de un concurso que consiste en ver quién se come más pimientos en menos tiempo. Y él, como casi […]

6:19 AM | Programming in the Life Sciences #17: The Open PHACTS scientific questions
Data needs for answering the scientific questions. Fromthe paper discussed in this post (Open Access).I think the authors of the Open PHACTS proposal made a right choice in defining a small set of questions that the solution to be developed could be tested against. The questions being specific, it is much easier to understand the needs. In fact, I suspect it may even be a very useful form of requirement analysis, and makes it hard to keep using vague terms. Open PHACTS has come up with 20 […]

7:26 PM | Telling True Stories That People Will Want to Read
How do you tell a good story about a fish that’s too boring to eat? And why would you even want to try? I found out why you’d want to cook this fish up into a story when I attended a workshop this week called “How to Write Good Stories about Science and Society.” One of the high points was listening to David Schleifer, a sociologist who partnered with writer Alison Fairbrother to tell the story of menhaden, a fish critical to the Atlantic’s ecosystem. Sounds like […]

6:59 PM | 'Direct writing' of diamond patterns from graphite a potential technological leap
What began as research into a method to strengthen metals has led to the discovery of a new technique that uses a pulsing laser to create synthetic nanodiamond films and patterns from graphite, with potential applications from biosensors to computer chips.

4:27 PM | Carl Sagan y Hermann Muller
Hermann J. Muller | FuenteHermann J. Muller (1890-1967) fue un destacado biólogo y experto en genética que ha pasado a la posteridad por sus trabajos sobre los efectos fisiológicos y genéticos de la radiación ionizante (mutagénesis por aplicación de rayos X). Estudió en la Universidad de Columbia, donde tuvo como mentor a Thomas H. Morgan, impartió clases en la Universidad de Texas hasta mediados de los años 30 como […]

4:06 PM | The Most Unexpected Mention of EPR You'll See This Week
In the middle of a very interesting, poignant and not-too-surprising article about people struck by lightning:Over the past three decades, Cooper has written articles on lightning safety, helped set up websites for survivors, and published many academic papers. A link on her UIC page points visitors to most of her work on the topic, including studies with esoteric titles such as “Electron Paramagnetic Resonance Spectroscopic Evidence of Increased Free Radical Generation and Selective […]

3:15 PM | Shape of things to come in nanoparticle platelet mimicry
For the first time, researchers have been able to integratively mimic the shape, size, flexibility and surface chemistry of real blood platelets on albumin-based particles. The platelet mimics halt bleeding in mouse models 65 percent faster than nature alone.

2:55 PM | Breaking down BPA and similar pollutants with sunlight, nanoparticles and graphene
Many pollutants with the potential to meddle with hormones are already common in the environment. In an effort to clean up these pollutants found in the soil and waterways, scientists are now reporting a novel way to break them down by recruiting help from nanoparticles and light.

2:43 PM | Is breast best?
Is it oversharing to tell you I wasn’t breastfed as an infant? Tough. I don’t feel that being bottlefed formula milk did me any harm. Breastfeeding is natural but it’s not always possible for new mothers and the push from the healthcare workers for breast is best waxes and wanes as any social fashion. There […]Is breast best? is a post from the science blog of science journalist, photographer and musician David Bradley Subscribe to our Email Newsletter

1:34 PM | Fully 3D-printed quantum dot LEDs
Researchers have demonstrated that they can print interwoven structures of quantum dots, polymers, metal nanoparticles, etc, to create the first fully 3D printed LEDs, in which every component is 3D printed. At the fundamental level, 3D printing should be entirely capable of creating spatially heterogeneous multi-material structures by dispensing a wide range of material classes with disparate viscosities and functionalities, including semiconducting colloidal nanomaterials, elastomeric […]

10:33 AM | Are we entering the nano era?
Modern hard drives only require an area of a few square nanometers for each bit of information. To protect ourselves from sunburn we use sunscreens that contain nanoparticles of titanium dioxide or zinc oxide. Is this the beginning of the nano era? Younan Xia from Georgia Institute of Technology pursues this question in his editorial.

8:08 AM | New study supports the use of a POSS molecule to strengthen aluminum alloys in automobiles
The study results show that TriSilanol POSS, created by silanol bonds at the corners of the POSS molecule, increased both the strength and toughness of A4047 and A359 aluminum alloys. In the A359 sample where POSS was added, elongation to failure increased from 23% to 250% over the control sample. According to the authors, these results hold great promise for the automotive industry.

4:52 AM | Strange Cover Art
A small part of me remembers a time before journal articles could all be accessed online. Back then, the cover art -- a creative expression of some of the newly-reported research between the covers -- could swing you towards one journal over another as you milled around the musty library stacks.Source: Wiley-VCH, c. 2014 / ACIEdoi: 10.1002/anie.201409223Nowadays, we've lost some of that artistic tradition, save for notable standouts Nature Chemistry and Angewandte Chemie. Hence, my […]
