In the on-going search for habitable exoplanets, astronomers have been searching for evidence of how planets orbiting distant stars were created. Although planet Earth’s "test kitchen" has provided a detailed recipe, it hasn’t been clear whether other planetary systems followed the same formula. Now, researchers are reporting evidence that the formula for Earth also applies to terrestrial exoplanets orbiting distant stars.
ONET networking software is for the setup, administration and control of large FT-NIR spectrometer networks. It is a server application accessed via a browser-based Web interface (WebUI), allowing users to set up, administrate and control a network of FT-NIR instruments from a central remote location anywhere in the world.
Although there are a diverse range of applications for predictive analytics in R&D, two common basic requirements are data and insight. Data may be generated by running experiments/analyses, or re-applied from previous work when available. Insights come from application of knowledge — both explicitand tacit. There are a variety of roles for informatics in predictive analytics...
Using an experiment carried into space on a NASA suborbital rocket, astronomers have detected a diffuse cosmic glow that appears to represent more light than that produced by known galaxies in the universe. The researchers say the best explanation is that the cosmic light originates from stars that were stripped away from their parent galaxies and flung out into space as those galaxies collided and merged with other galaxies.

For the first time, scientists have discovered how to produce ultra-thin "diamond nanothreads" that promise extraordinary properties, including strength and stiffness greater than that of today's strongest nanotubes and polymers. The core of the nanothreads is a long, thin strand of carbon atoms arranged just like the fundamental unit of a diamond's structure.
The Alpha Magnetic Spectrometer collaboration has presented its latest results based on analysis of 41 billion particles detected with the space-based AMS detector aboard the International Space Station. The results, presented during a seminar at CERN, provide new insights into the nature of the mysterious excess of positrons observed in the flux of cosmic rays.
North American lions, cheetahs and short-faced bears: Those are just a few fearsome critters from 25,000 years ago paleontologists already might have found in their first excavation of a bizarre northern Wyoming cave in 30 years. Good fossils also come in small packages: Exquisite rodent bones best examined by microscope, or even snippets of genetic material from long-extinct species, could be in their haul.
As turboprop and jet aircraft climb or descend under certain atmospheric conditions, they can inadvertently seed mid-level clouds and cause narrow bands of snow or rain to develop and fall to the ground, new research finds. Through this seeding process, they leave behind odd-shaped holes or channels in the clouds, which have long fascinated the public.
Tandem protein mass spectrometry is one of the most widely used methods in proteomics, the large-scale study of proteins, particularly their structures and functions. Researchers in the Marcotte group at the University of Texas at Austin are using the Stampede supercomputer to develop and test computer algorithms that let them more accurately and efficiently interpret proteomics mass spectrometry data.
The Program Committee has announced a call for papers for the Pittcon 2015 Technical Program. Abstracts are currently being accepted for contributed oral and poster presentations in areas such as, but not limited to, analytical chemistry, applied spectroscopy, life science, bioanalysis, food science, nanotechnology, environmental science and pharmaceutical. The 2015 committee is especially interested in topics relevant to energy and fuels.
This colorful cosmic rainbow portrays a section of Saturn’s beautiful rings, four centuries after they were discovered by Galileo Galilei. Saturn’s rings were first observed in 1610. Despite using his newly created telescope, Galileo was confounded by what he saw: he referred to the peculiar shapes surrounding the planet as “Saturn’s children.”
In a view from high altitude, height can be a difficult thing to gauge. The highest of clouds can appear to sit on a flat plane, as if they were at the same elevation as the ocean or land surface. In this image, however, texture, shape and shadows lend definition to mushrooming thunderheads over the Indonesian island of Flores. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite acquired this image
The Clarity MS Extension control driver for Advion’s expression compact mass spectrometers (CMS) includes both digital control of the detector and digital data acquisition of the detector signal. It also allows performance of all service operations necessary for the detector from the Device Monitor software window.
Scientists are using powerful analytical and imaging tools to study artworks from all ages, delving deep below the surface to reveal the process and materials used by some of the world’s greatest artists. Chemist Richard Van Duyne, in collaboration with conservation scientists at the Art Institute of Chicago, has been using a scientific method to investigate masterpieces by Pierre-Auguste Renoir, Winslow Homer and Mary Cassatt.
Tens of thousands of pot smokers wheezed a sigh of relief when recreational marijuana use was made legal January 1, 2014. Gone is the cottage industry of gray-area physicians rubber-stamping medical prescriptions for a well-informed gaggle of would-be stoners who memorized popular conditions sure to garner approval.
When life on Earth was first getting started, simple molecules bonded together into the precursors of modern genetic material. A catalyst would have been needed, but enzymes had not yet evolved. One theory is that the catalytic minerals on a meteorite’s surface could have jump-started life’s first chemical reactions. But scientists need a way to directly analyze these rough, irregularly shaped surfaces.
Creating surrogate human organs, coupled with insights from highly sensitive mass spectrometry technologies, a new project is on the brink of revolutionizing the way we screen new drugs and toxic agents.
For the first time, the ASACUSA experiment at CERN has succeeded in producing a beam of antihydrogen atoms. Primordial antimatter has so far never been observed in the Universe, and its absence remains a major scientific enigma. Nevertheless, it is possible to produce significant amounts of antihydrogen in experiments at CERN by mixing antielectrons (positrons) and low energy antiprotons produced by the Antiproton Decelerator.
The Pittcon Organizing Committee has announced that Innovative Publishing, producer of Food Labs Conference and publisher of Food Safety Tech eJournal, has signed an agreement for the second year for the co-location of Food Labs Conference to be held in conjunction with Pittcon 2014.
Ah, 30,000 feet and some old Dire Straits on the headphones, and waiting for my warm Heineken. Perfect. Though I enjoy lambasting companies that get it wrong, I’m also quick to stomp my feet and clap my hands when companies get it right. And I’ll do that, I promise, but allow me my fun first.
A new imaging method for analyzing biological samples based on their chemical makeup is set to transform the way medical scientists examine diseased tissue. Researchers at Imperial College London have outlined a recipe for processing mass spectrometry imaging data and building a database of tissue types.
Data Integrity in a Nutshell: Industry must take bold steps to assure the data used for drug quality decisions is trustworthyJanuary 7, 2014 12:31 pm | by Mark E. Newton | Articles | Comments
Regulatory inspectors have started digging much deeper into data, no longer accepting batch release data and supportive testing at face value. Even worse, this effort is justified: they have cited a number of firms for violations of data integrity, a most fundamental bond of trust between manufacturers and the regulators that inspect them. Industry must take bold steps to assure the data used for drug quality decisions is trustworthy...
Data integrity is a current hot topic with regulatory agencies, as seen with recent publications in this magazine, and audit trails are an important aspect of ensuring this in computerized systems. The purpose of this article is to compare and contrast the EU and FDA GMP regulatory requirements for computerized system audit trails.
