A fly's tiny brain may hold huge human benefits
Before swatting at one of those pesky flies that come out as the days lengthen and the temperature rises, one should probably think twice. view more (2008-03-25)
BIOTECHNICA 2003: At the Pulse of the Chip Lab
The clinical and industrial analytics as well as diagnostics show an increasing demand for more sensitive and more rapid detection methods using smallest sample volumes. Within the BMBF joint project "MODULAB" a „chip-based-lab" construction kit is developed in which all the necessary working steps can be performed in separate... view more... (2003-10-07)
High-pressure chemistry in ultra small pressure cooker
Small, clever process technology is essential for the future, but is it possible? Dutch-sponsored researcher Fernando Benito López investigated the possibilities of the so-called lab-on-a-chip: microreactor chips in which chemical reactions can take place under (high) pressure. view more (2007-04-16)
Experts research world-first tests for allergic reactions to medication
It is estimated that up to 10,000 UK hospital patients each year suffer an allergic reaction to anaesthetics, and that one in every 100-200 consumers of penicillin has an allergic response to it. Allergic reactions to fairly common medications generally occur unexpectedly and often within minutes of drug administration, but there are few... view more... (1999-05-24)
Wastewater produces electricity and desalinates water
A process that cleans wastewater and generates electricity can also remove 90 percent of salt from brackish water or seawater, according to an international team of researchers from China and the U.S. view more (2009-08-07)
Enzymatic reaction rate surprises researchers
Enzymatic reactions, which are crucial in biological processes, can occur much faster than previously thought possible, as researchers at the biophysics department of the Faculty of Exact Sciences of the Vrije Universiteit Amsterdam have discovered. Their findings were published on line on 5 May in Nature Structural Biology (www.nature.com/nsb).... view more... (2003-05-07)
Some masks used in children's asthma treatment not effective, research shows
Some face masks commonly used to help young children inhale asthma medicine are not effective, according to a new study by researchers from Wake Forest University School of Medicine. view more (2006-02-06)
New Type Of Reactor Developed For Cleaner, Safer Chemical Processing
Scientists in the UK are using an unusual form carbon dioxide in a new type of reactor capable of carrying out commercially important chemical processes which could be cheaper, safer and cleaner than their conventional counterparts. The work, reported in this month’s EPSRC Newsline is being carried out at the University of Nottingham led by... view more... (2001-02-05)
Possible genetic basis for alcohol abuse discovered
Alcoholism seems to have its roots at least partly in the genes. How genetic factors contribute to alcohol abuse is still an important question to be solved. There are hints that the body produces an opiate-active compound that may enhance alcohol addiction. New studies at the University of Bonn suggest that a gene is at least partly responsible... view more... (2001-04-18)
A MANAGEMENT PLAN FOR PATIENTS WITH NUT ALLERGIES (pp 87, 111)
In this week’s issue of THE LANCET, researchers from Cambridge, UK, report the success of a newly designed management strategy for people with potentially fatal allergies to peanuts and other nuts. Despite the high level of media attention given to nut allergies, little is known about the clinical features of such disorders, and strategies... view more... (2001-01-11)
Space technology disposes of sludge
Research funded by the European Space Agency into ways of feeding future astronauts on missions to Mars is about to find a very down-to-earth application - how to dispose of the sewage sludge left over after wastewater treatment. The MELISSA (Micro-Ecological Life Support Alternative) project, which ESA is funding in companies and research... view more... (2002-05-15)
Shedding light on cancer cells
Scientists label cells with coloured or glowing chemicals to observe how basic cellular activities differ between healthy and cancerous cells. Existing techniques for labelling cells are either too slow or too toxic to perform on live cells. view more (2009-09-25)
New device allows safe and fast access to Large Space Simulator
A new 'specimen access device' (SPAD) to allow safe and fast access to spacecraft being tested in the Large Space Simulator chamber is now fully operational at ESA's Test Centre. The SPAD is basically a customised crane, carrying a basket to move an operator inside the Large Space Simulator (LSS). The LSS is a huge chamber at ESA's European... view more... (2005-03-22)
Canberra parents lack allergy awareness: Study
Nearly four per cent of ACT kindergarten children have a peanut allergy and while the region's schools are well prepared to cope with this, some parents are taking inappropriate action when dealing with their child's allergy, according to a new study. view more (2009-03-17)
New nano device detects immune system cell signaling
Scientists have detected previously unnoticed chemical signals that individual cells in the immune system use to communicate with each other over short distances. view more (2008-09-04)
Batch control makes chemical reactions easier to manage
Two Dutch researchers have developed a method for managing so-called batch productions. During a batch production, substances react in a reactor vessel according to a certain recipe to produce an end product. After the reaction the reactor is emptied and a new reaction with the same recipe is started. Chemist Eric van Sprang and chemical engineer... view more... (2004-04-13)
University of Pennsylvania Chemists Reinvent the Science and Industry of Making Plastics
Chemists at the University of Pennsylvania have created a new process for free radical polymerization, the chemical reaction responsible for creating an enormous array of everyday plastic products, from Styrofoam cups to PVC tubing to car parts. view more (2006-10-13)
Microbes turn electricity directly to methane without hydrogen generation
A tiny microbe can take electricity and directly convert carbon dioxide and water to methane, producing a portable energy source with a potentially neutral carbon footprint, according to a team of Penn State engineers. view more (2009-03-31)
Solution to elusive problem
Scientists at the University of Leicester are on the way to solving a problem that has long beset chemists trying to study chemical reactions. To establish reaction mechanisms the observation of reaction intermediates is vital, but they are incredibly short-lived under normal conditions, and therefore difficult to detect. Freezing... view more... (2003-01-21)
Students with food allergies often not prepared
College students with food allergies aren't avoiding the foods they know they shouldn't eat. Students of all ages are not treated with potentially life-saving epinephrine as often as they should be. And instructors, roommates and friends often are not aware of what to do if a food-allergic student has a reaction. view more (2008-08-06)
