Smallest 3D printed drill in the world maybe  Lance Abernethy, a maintenance engineer from Auckland, New Zealand, 3D printed a cordless drill that measures 0.67 inches (17mm) tall, 0.27 inches (7.5mm) wide, and 0.5 inches (13mm) long and holds a 0.02 inches (0.5mm) twist drill. Not happy with that, he is already working on a smaller version

Hats off to artist +ODEITH Anamorphic Writing , from Portugal.
  Odeith was born in 1976, in Damaia (Portugal). He held a spray can for the first time in the mid 1980s, but it was in the 1990s, when graffiti began its dissemination throughout Portugal and began to leave its Portuguese birthplace, Carcavelos, that the artist had his first contact with graffiti and its movement. His first experiences were sketched on street walls and train tracks and so the passion...

Gentle Alarm
The best alarm app. It is easy to take for granted a basic app we use everyday, specially when it is reliable, highly customizable and easy to use. But Gentle Alarm has these qualities only because it is well done and lots of work went into it.
So kudos to the developers!

“As a human, though, it’s a stark reminder that our choices have consequences, and the door is rapidly closing on our opportunities to choose a different future.” - scientist Katharine Hayhoe of Texas Tech University
Scientists confirm that climate change is stalling a major Atlantic Ocean current, and that could lead to flooding and food shortages.

Very innovative 3D printing method.
 
New revolutionary 3D printing technology inspired by Terminator 2 "...new continuous 3D printer would do away with the layers entirely. Instead, a platform draws the object continuously out of a bath of liquid resin."

SOURCES:

Science - original paper:

Continuous liquid interface production of 3D objects
http://www.sciencemag.org/content/early/2015/03/16/science.aaa2397

Abstract: "Additive manufacturing processes such as 3D printing use time-consuming, stepwise layer-by-layer approaches to object fabrication. We demonstrate the continuous generation of monolithic polymeric parts up to tens of centimeters in size with feature resolution below 100 micrometers. Continuous liquid interface production is achieved with an oxygen-permeable window below the ultraviolet image projection plane, which creates a “dead zone” (persistent liquid interface) where photopolymerization is inhibited between the window and the polymerizing part. We delineate critical control parameters and show that complex solid parts can be drawn out of the resin at rates of hundreds of millimeters per hour. These print speeds allow parts to be produced in minutes instead of hours."

http://phys.org/news/2015-03-revolutionary-3d-technology.html

"A 3D printing technology developed by Silicon Valley startup, Carbon3D Inc., enables objects to rise from a liquid media continuously rather than being built layer by layer as they have been for the past 25 years, representing a fundamentally new approach to 3D printing. The technology, to appear as the cover article in the March 20 print issue of Science, allows ready-to-use products to be made 25 to 100 times faster than other methods and creates previously unachievable geometries that open opportunities for innovation not only in health care and medicine, but also in other major industries such as automotive and aviation.

Joseph M. DeSimone, professor of chemistry at UNC-Chapel Hill and of chemical engineering at N.C. State, is currently CEO of Carbon3D where he co-invented the method with colleagues Alex Ermoshkin, chief technology officer at Carbon 3D and Edward T. Samulski, also professor of chemistry at UNC. Currently on sabbatical from the University, DeSimone has focused on bringing the technology to market, while also creating new opportunities for graduate students to use the technique for research in materials science and drug delivery at UNC and NCSU.

The technology, called CLIP - for Continuous Liquid Interface Production - manipulates light and oxygen to fuse objects in liquid media, creating the first 3D printing process that uses tunable photochemistry instead of the layer-by-layer approach that has defined the technology for decades. It works by projecting beams of light through an oxygen-permeable window into a liquid resin. Working in tandem, light and oxygen control the solidification of the resin, creating commercially viable objects that can have feature sizes below 20 microns, or less than one-quarter of the width of a piece of paper.

"By rethinking the whole approach to 3D printing, and the chemistry and physics behind the process, we have developed a new technology that can create parts radically faster than traditional technologies by essentially 'growing' them in a pool of liquid," said DeSimone, who revealed the technology at a TED talk on March 16 in the opening session of the conference in Vancouver, British Columbia.

Through a sponsored research agreement between UNC-Chapel Hill and Carbon 3D, the team is currently pursuing advances to the technology, as well as new materials that are compatible with it. CLIP enables a very wide range of material to be used to make 3D parts with novel properties, including elastomers, silicones, nylon-like materials, ceramics and biodegradable materials. The technique itself provides a blueprint for synthesizing novel materials that can further research in materials science.
Rima Janusziewicz and Ashley R. Johnson, graduate students in DeSimone's academic lab, are co-authors on the paper and are working on novel applications in drug delivery and other areas.

"In addition to using new materials, CLIP can allow us to make stronger objects with unique geometries that other techniques cannot achieve, such as cardiac stents personally tailored to meet the needs of a specific patient," said DeSimone. "Since CLIP facilitates 3D polymeric object fabrication in a matter of minutes instead of hours or days, it would not be impossible within coming years to enable personalized coronary stents, dental implants or prosthetics to be 3D printed on-demand in a medical setting."

CLIP's debut coincides with the United Nation designating 2015 as the International Year of Light and Light-Based Technologies, which recognizes important anniversaries of scientific advances enabled with light."

Story
Tagline
Gaúcho nas Pradarias (Univ. of Alberta, CFD, openSUSE)
Introduction
Gaúcho from the Brazilian Pampas, I am an engineer and Linux enthusiast. 
Gaúcho dos Pampas brasileiros, sou engenheiro e fã do Linux (e torcedor do Internacional).
(profile cover: Edmonton River Valley by Justin Wondga)

I teach mostly numerical simulation to Mechanical Engineering students. 
I apply computer models to study the winds on Mars, the production of droplets in human cough, and Netzero Energy Houses (houses that produce as much energy as they consume). Check out my university page.

I am also a Christian, more precisely a confessional Lutheran affiliated with the Lutheran Church-Canada. I disagree with Einstein and I believe there is only one way I can live my life: working within the limitations of logic and Physics as though nothing is a miracle (secondary causes), but knowing full well that at the most fundamental and metaphysical level, where the scientific method does not apply and experiments cannot be replicated, everything is a miracle (Primary Cause). And here is why I do Science: Psalm 111:2.

Sou também cristão, mais especificamente luterano confessional. Cresci na IELB e hoje sou membro da LCC. Eu discordo do Einstein e penso que há somente uma maneira de viver minha vida: trabalhando dentro das limitações da lógica e da física, como nada fosse um milagre (causas secundárias), mas tendo a certeza de que, no nível mais fundamental e metafísico, onde o método científico não se aplica e experimentos não são reproduzíveis, tudo é um milagre (Causa Primária). E aqui está porque sou cientista: Salmo 111.2.
