Taking evolution's temperature: Researchers pinpoint the energy it takes to make a species
Writing this week in the Proceedings of the National Academy of Sciences, scientists say higher temperatures near the equator speed up the metabolisms of the inhabitants, fueling genetic changes that actually lead to the creation of new species.   view more (2006-06-01)

Chemical coffee maker promises purer medicines
Their method uses pressurised carbon dioxide as a solvent, because it allows chemical reactions which usually create a mixture of products to produce only one. Project leaders Chris Rayner and Tony Clifford believe it could change the way pharmaceuticals are manufactured in the future. "If the... view more (1999-03-15)

ETH Project with Costa Rica Set up for Drug Discovery
Nature produces highly interesting substances, which for years have met with great scientific interest. Chance, such as is used for instance in combinatorial chemistry for the synthesis of compounds, cannot replace the intelligence of nature, especially not in terms of the structural diversity of... view more (2003-05-19)

Focus on functional materials development shortchanges opportunities for discovery
The current research focus on "functional polymers" can overlook the opportunity for important discoveries that can arise from basic research on how things work, said a distinguished chemist.   view more (2006-09-11)

Novel mechanism for DNA replication discovered
Since the discovery of the structure of DNA by James Watson and Francis Crick in 1953, the paradigm for DNA replication has stated that the DNA itself codes for the appropriate pairings for replication.   view more (2005-09-30)

Bad cholesterol inhibits the breakdown of peripheral fat
he so called bad cholesterol (LDL) inhibits the breakdown of fat in cells of peripheral deposits, according to a study from the Swedish medical university Karolinska Institutet. The discovery reveals a novel function of LDL as a regulator of fat turnover besides its well-established detrimental... view more (2008-11-20)

Brewing up potential anti-cancer drugs from green tea
Drinking green tea has a protective effect against some forms of cancer but drinking large amounts can increase the risk of birth defects such as spina bifida - according to previous epidemiological studies.   view more (2005-03-14)

Quantum dots reviewed — Could these nanoparticles hold the cure to cancer?
The worlds of medical and biological research are abuzz with the promises offered by nanoparticles known as semiconductor quantum dots. These Quantum Dots (QDs) have unique optical and electronic properties that make them suitable for breakthrough treatments such as the detection and destruction of... view more (2006-09-15)

Tuberculosis drug shows promise against latent bacteria
A new study has shown that an investigational drug (R207910, currently in clinical trials against multi-drug resistant tuberculosis strains) is quite effective at killing latent bacteria. This revelation suggests that R207910 may lead to improved and shortened treatments for this globally prevalent... view more (2008-09-15)

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... view more (2001-04-18)

Wound Healing - Discovery Of A New Therapeutic Strategy Against Hypertrophic Scarring
Wound healing appears generally a banal event, but in a certain proportion of cases it evolves inappropriately in hypertrophic scars resulting in skin and organ deformations. This is due to an excess of wound contraction, a phenomenon that generally helps to close the wound. Hypertrophic scarring... view more (2002-05-13)

New synthetic self-assembling macromolecules mimic nature
We take "self-assembly" for granted when it is carried out by the biopolymers which are our hair, teeth, or skin. But when scientists devise new ways for molecules to self assemble into new materials, it is an important achievement.   view more (2007-03-20)

Stress causes parodontis
Under stress, major proteins get actively destroyed in the parodentium. According to biologists' data, chronical stress inhibits the osseous tissue maturing process and intensifies decomposition of collagen protein and proteoglycans with the animals non-resistant to stress. Stress intensifies... view more (2003-09-26)

Nanotechnology for Space Applications
Ever more fastidious missions for the scientific investigation of space as well as the increasing use of satellite-based services require the development of more efficient, more economical and more resistant space technologies and systems in the future. A study of the VDI Technology Center on... view more (2003-04-14)

New peptide antibiotic isolated from American oyster
North Carolina Sea Grant researchers have isolated a new peptide antibiotic from the American oyster that may have implications for managing many diseases in oysters.   view more (2005-11-30)

Growing tiny carbon nanotube wires to connect computer chips of the future
Computers and electronic devices of the future will utilise technologies not currently available.   view more (2007-11-26)

Large burns open up a can of worms
Large burns can trigger cardiac problems and enhanced inflammatory and hypermetabolic responses in patients, a study in the online open access journal Critical Care suggests. Effective treatments may need to focus on these multiple aspects.   view more (2007-08-23)

Scientists crack 40-year-old DNA puzzle and point to 'hot soup' at the origin of life
A new theory that explains why the language of our genes is more complex than it needs to be also suggests that the primordial soup where life began on earth was hot and not cold, as many scientists believe.   view more (2005-08-03)

University of Kent bioscientists receive grant to research novel cancer treatment
Dr Phil Blower and Dr Dan Lloyd from the Department of Biosciences at the University of Kent - together with Dr Paul Marsden at the St Thomas' Hospital Clinical PET Centre in London - have been awarded £347,906 from the Engineering and Physical Sciences Research Council and the Medical... view more (2004-03-16)

Caught in Flight
Chemists are very interested in unusual molecules that are made from atoms of a single element. For example, fullerenes ("buckyballs") and nanotubes, made of pure carbon, are generating a lot of excitement among materials scientists. If all were as it should be, the element phosphorus should be... view more (1999-11-24)

Novel approach for rapid identification and development of malaria vaccines
Malaria is the world's most frequent parasitic disease, affecting more than 100 countries in the tropical zones, mostly in Africa, and 40% of the world population, with more than a million deaths per year.   view more (2007-07-25)

£11.5m for new structural proteomics research programmes
BBSRC has announced two new research programmes that together will receive £11.5m under the Structural Proteomics of Rational Targets Initiative (SPoRT). The Membrane Protein Structure Initiative (MPSI), a consortium of experienced membrane research groups at universities and institutes... view more (2004-06-17)

Researchers discover how antibiotic inhibits bacterial growth
Researchers at the University of Illinois at Chicago, in collaboration with research teams from Pharmacia & Upjohn and Pfizer, have discovered precisely how the antibiotic linezolid inhibits bacterial growth.   view more (2007-05-11)
