At the Julius Kühn Institute, the Federal Research Institute for Cultivated Plants in Germany, a young working group is trying to specifically modify the genetic material of plants, through genome editing. In this way, they also want to investigate possible risks of this technology. LAB Worldwide visited the team for one day.

Extremely sensitive analytical instruments capable of assaying analytes in the femtogram range have meanwhile become standard equipment in many laboratories. But their accuracy in analysis of drinking water is decisively influenced by the right choice of syringe filter unit, as described in this article.

Life sciences laboratories are another area in which plastic waste can be reduced. Approximately 5.5 million tons of plastic waste are produced every year in life sciences laboratories alone, including items like pipette tips, nitrile gloves, cell culture flasks. In the age of global waste pollution and the ubiquity of plastic in the world around us, this is definitely too much. It can’t all be changed, but improvements are possible in some areas.

Women can turn to a variety of methods to determine the best time in their menstrual cycle for conception. Volatile biomarkers have proven useful indicators in other contexts and now, the analysis of biogenic VOCs has been shown to provide insights on female fertility.

The determination of moisture in cured cannabis is an indicator of microbial contamination, a key variable used to calculate other constituent results on a dry basis and required for the pressing process of extracting CBD oil from cannabis. Thermogravimetric moisture determination can provide valuable services here.

Whether employed in basic research or the production of biopharmaceuticals, monoclonal antibodies are used in an exceptionally wide range of applications. Until now, harvesting of mammalian cell cultures used to be time-consuming, especially at laboratory scale, and usually involved a centrifugation step. A new diatomaceous earth-based filtration solution now improves and accelerates this process significantly.

Dr. Thomas Schinecker talks about demographic change, health policy and how increasing complexity can be managed for the benefit of patients, physicians, laboratories and the health care system. The interview was conducted by Dr. Ilka Ottleben from the LP editorial team.

Artificial intelligence and 80,000 ancient Chinese poems show that constraint poetic structures aid poetry appreciation

Food testing laboratories need reliable data management systems in order to comply with the ever increasing regulatory requirements. LIMS platforms play an important role in terms of compliance with HACCP and ISO 17025 as well as in the implementation of comprehensive security mechanisms.

Carbohydrates are the most abundant class of biomolecules. But — their analysis is not always trivial. This article describes how electrolytic and highly automated inline eluent generation can be successfully applied to carbohydrate separations using HPAEC in combination with PAD.

Much better treatment options now exist for many illnesses compared to what was available ten years ago. Their effectiveness depends, however, on early detection. Laboratory diagnostics create a highly dynamic bond between scientific progress and medical applications.

Heating mantles are supposed to enable the user to heat liquids safely and quickly – even in cases of (accidental) misapplication. This is now taken into account by a modified EN Standard. And it is of great importance for users to know: a violation may have unexpected consequences

For some years, an active substance from the leaves of an ornamental plant has been regarded as a possible forerunner of a new group of potent drugs. So far, however, it has been very laborious to manufacture it in large quantities. That could now change: Researchers at the University of Bonn have identified a bacterium that produces the substance and can also be easily cultivated in the laboratory.

Heavy metal contamination in food and water poses a threat to humans and animals. The toxicity of elements such as chromium, mercury and arsenic varies depending on their oxidation state. Food analysis is a very effective method for positively identifying the oxidation state.

Ultimately, every analysis relies on detection, and in most cases one of the many spectroscopic procedures is used for this. What is happening in this extremely wide-ranging field, and what trends are hot right now?

Food is both a basic need and a valuable asset. In Germany, food manufacturers must meet high requirements in terms of safety and product quality. Read about the important contribution microscopic techniques make in quality control and R&D.

Fibre determination is in particular important for the analysis of animal feed. Therefore it reproduces the steps of the digestive process in an animal’s stomach. A new method makes dissolving and filtering the components significantly easier and ensures more reliable, reproducible analysis results.

Employees in a laboratory often have to handle hazardous or easily ignitable substances. What benefits can networked solutions for storage of hazardous substances bring and what do the technical solutions look like in detail?

To clarify whether and when a handgun was fired, forensic scientists search for and analyze Gunshot Residue (GSR) deposits. One highly interesting aspect of GSR is the presence of volatile organic chemical residues, which can offer clues as to when a weapon was fired. An innovative extraction technique based on Headspace Sorptive Extraction (HSSE) and Gerstel Twister has now been shown to extract additional information from spent cartridges.

From morning rush-hour urban air-pollution to ship diesel emissions — organic particulate matter directly affects air quality and health while its analysis is still challenging. A new technological solution for PTR-TOFMS shall now find a remedy.
