11:00 AM | 9103 Picoammeter Actuel Update: Micro Window Display
The Problem: Using Actuel to control and measure current with the 9103 Picoammeter takes up valuable screen real estate: Actuel is RBD’s Windows application for controlling the 9103 USB Picoammeter. It also provides features like measuring, recording, and graphing current. Although the … Continue reading → The post 9103 Picoammeter Actuel Update: Micro Window Display appeared first on RBD TechSpot.

11:00 AM | Fear Bola and Duct Tape...
"Sell the fear": it was the instruction I received in a very uneventfully short career as a sales representative for an electronics security firm. Part of the memorized script I recited that entailed sharing horrid crime stats to wearied prospective buyers was "how did that make you feel?" It was of course, supposed to make you feel afraid, very afraid...for your lives and reaching for your checkbooks. At an appointment scheduled through the office, before I could launch into my memorized […]

10:30 AM | Slack for science
Is Slack.com the right collaborative tool for science? I have just start to test its capabilities.  My hope is that it will combine many platforms and separated tools into one organic, searchable and multi-platform service. For scientific research I now use Dropbox for file sharing, Googledocs and Sharelatex for article writing, Papers for article management, Evernote […]

10:02 AM | Researcher develop economical process for micro energy harvesting
The trend toward energy self-sufficient probes and ever smaller mobile electronics systems continues unabated. They are used, for example, to monitor the status of the engines on airplanes, or for medical implants. They gather the energy they need for this from their immediate environment - from vibrations, for instance. Researchers have developed a process for the economical production of piezoelectric materials.

8:58 AM | “I fight monsters. I can’t fight physics.”
Sometimes this blog languishes a little because I don’t know what to write. I’ve got a stock of articles written, but it’s hard to know what’s topical and others will find interesting, so I don’t post a lot of what I write. Sometimes, though, things become topical and I get the excuse I wanted to […]

8:38 AM | Direct chemical contrast in STM imaging becomes available with new technique
Researchers have demonstrated a new imaging technique that is a marriage between two powerful methods and it promises simultaneous spatial and elemental information of the samples down to the atomic scale. By combining scanning tunneling microscopy (STM) with synchrotron X-ray microscopy, there is now an instrument (SX-STM) that has the potential to perform all the applications of STM and X-rays in a single setting at the ultimate atomic limit.

8:25 AM | New nanodevice to improve cancer treatment monitoring
In less than a minute, a miniature device can measure a patient's blood for methotrexate, a commonly used but potentially toxic cancer drug. Just as accurate and ten times less expensive than equipment currently used in hospitals.

8:00 AM | Don’t Tell Me My Love is Wrong!
Doing Elitism Wrong This kind of cheap, lazy elitism ticks me off. It says nothing about why science is hard to understand, and it doesn’t even get the frustrations of the job right. I mean, “collecting data”? “Dense research articles”? Neither of those necessarily implies tedium or drudgery. Shockingly, not everything which requires patience and [...]

4:00 AM | ZTF, si apre l’era della ‘cinematografia celeste’
Grazie ad un finanziamento di 9 milioni di dollari della National Science Foundation (NSF) e di altri fondi provenienti dalla collaborazione Zwicky Transient Facility (ZTF), gli scienziati dell’osservatorio Palomar del Caltech stanno costruendo una nuova fotocamera che sarà in grado di monitorare l’emisfero settentrionale in una sola notte alla ricerca di supernove, buchi neri, asteroidi vicini alla Terra e […]

6:53 PM | Over the Moon with China and Luxembourg
Predicting the future, especially of something subject to the winds of political misfortune as space exploration, is problematic. However, it’s a safe bet it won’t look like it did during the first few decades. More nations than ever are interested in sending spacecraft into orbit and beyond (including crewed spaceships), and privately-owned companies are taking […]

5:51 PM | La máquina de Turing
A principios de 1936, un joven Alan Turing terminó un artículo que sentó en gran parte las bases de lo que sería un ordenador actual. Para resolver el Entscheidungsproblem, uno de los problemas que traían de cabeza a los matemáticos de la época, Turing ideó un sorprendente experimento mental. Había nacido la máquina de Turing. Alan empezó […]

Il premio Nobel venne assegnato per la prima volta nel 1901 a seguito delle ultime disposizioni testamentarie di Alfred Nobel, chimico e filantropo nonché inventore della dinamite.Il premio è diventato ben presto uno dei più prestigiosi al mondo e, nell'ambito della fisica, il primo a riceverlo fu lo scopritore dei raggi X, il tedesco Wilhelm Conrad Röntgenin riconoscimento dello straordinario servizio reso per la scoperta delle importanti radiazioni che in seguito […]

2:31 PM | Regge theory
http://t.co/alaasqcHwl @ulaulaman says #goodbye to #TullioRegge In quantum physics, Regge theory is the study of the analytic properties of scattering as a function of angular momentum, where the angular momentum is not restricted to be an integer but is allowed to take any complex value. The nonrelativistic theory was developed by Tullio Regge in 1957.Following Chew and Frautschi (pdf), the key papers by Tullio Regge are: Regge T. (1959). Introduction to complex orbital momenta, Il Nuovo […]

3:40 AM | Heating from Cosmic Chaos
Irina Zhuravleva We are pleased to welcome Irina Zhuravleva as a guest blogger today. Irina is the first author of a new paper describing a crucial role of gas turbulence in interaction between supermassive black holes and hot gas in galaxy clusters, the subject of our latest press release. Irina studied theoretical astrophysics in the department of mathematics and mechanics at Saint Petersburg State University in Russia, followed by a PhD in astrophysics at Max Planck Institute for […]

3:21 AM | NASA's Chandra Observatory Identifies Impact of Cosmic Chaos on Star Birth
These two Chandra images of galaxy clusters - known as Perseus and Virgo - have provided direct evidence that turbulence is helping to prevent stars from forming. These new results could answer a long-standing question about how these galaxy clusters keep their enormous reservoirs of hot gas from cooling down to form stars, as discussed in our latest press release [link to PR]. Galaxy clusters are the largest objects in the Universe held together by gravity. They contain hundreds or thousands […]
