Today's Science News
Understanding of how mosquitoes find a host
The potentially deadly yellow-fever-transmitting Aedes aegypti mosquito detects the specific chemical structure of a compound called octenol as one way to find a mammalian host for a blood meal.Saving Peak District moorlands
Seventy-five per cent of the world's heather moorlands are in the UK. Several organisations in the Peak District National Park are trying to restore and conserve the moorland habitat.Delicious new all-oat or all-barley breads
Researchers want to develop new and tasty whole-grain oat or barley breads that offer antioxidants, fibre, and other components in an array different from that found in today's whole-wheat breads.
Pharmacology
Mechanism behind Ritalin leaning boost
Doctors treat millions of children with Ritalin every year to improve their ability to focus on tasks, but scientists now report that Ritalin also directly enhances the speed of learning.GE Healthcare Launches Biacore 4000
GE Healthcare is launching Biacore 4000, a powerful solution for large-scale, label-free molecular interaction analysis in drug discovery, from early screening to characterisation.Unique family of anti-cancer compounds
Scientists have streamlined the process for synthesising a family of compounds with the potential to kill cancer and other diseased cells, and have found that they represent a unique category of anti-cancer agents.
Nanotechnology
World-leading nanoscience institutes join forces
Two of the world's leading nanoscience institutes have entered into an agreement for research collaboration and educational exchange in nanoscience and nanotechnology.Nanoparticles target and kill cancer cells
Another weapon in the arsenal against cancer: Nanoparticles that identify, target and kill specific cancer cells while leaving healthy cells alone.Designer nano luggage to carry drugs
For the first time, scientists have succeeded in growing empty particles derived from a plant virus and have made them carry useful chemicals.
Environment
Grant ensures a sustainable future for software
A sustained future for this valuable resource has now been assured thanks to a multi-million pound grant from Engineering and Physical Sciences Research Council, which will establish the UK's Software Sustainability Institute.Shore thing for sea shell scientists
Scientists have made synthetic 'sea shells' from a mixture of chalk and polystyrene cups - and produced a tough new material that could make our homes and offices more durable.Sources of pollution in waterways
Polycyclic aromatic hydrocarbons are components of petroleum products such as gasoline, coal, and oil. They are also produced as by-products of the combustion of fuels including petroleum and fire wood.
Biotechnology
Bone marrow can harbour HIV-infected cells
Scientists have identified a new reservoir for hidden HIV-infected cells that can serve as a factory for new infections.Novel approach to prostate cancer treatment
Researchers in Canada have detected a novel oncolytic viral therapy against prostate cancer with use of a virus called the reovirus, according to study results.Periodontal pathogens enhance HIV-1
Although oral co-infections are highly prevalent in HIV-1 patients and appear to positively correlate with viral load levels, the potential for oral bacteria to induce HIV-1 reactivation in latently infected cells has received little attention.
Genetics
Eggshell of extinct giant bird unlocks key to ancient DNA
Ancient DNA from the fossil eggshell remains of the extinct elephant bird, has been successfully extracted thanks to help from a University of Sheffield expert - marking a world-first for archaeology and genetics.A fingerprint for genes
Cells may not have a mouth, but they still need to ingest substances from the external environment. If endocytosis is affected, it can lead to a variety of diseases.Food allergy linked to master gene
Scientists have identified a region of a human chromosome that is associated with eosinophilic esophagitis, a recently recognised allergic disease.
