From snowflakes to the leaves on a tree, objects in nature are made of irregular molecules called fractals. Scientists now have created and captured an image of the largest man-made fractal molecule at the nanoscale.
The molecule, developed by researchers at the University of Akron, Ohio University and Clemson University, eventually could lead to new types of photoelectric cells, molecular batteries and energy storage, according to the scientists, whose study was published onl
Pollution clouds in region appear to ’mask’ aspects of South Asian climate, leading to drought and other impacts
A new analysis by scientists at Scripps Institution of Oceanography at the University of California, San Diego, has produced surprising results showing how air pollution, global warming-producing greenhouse gases and natural fluctuations in the climate may have a range of significant consequences on the world’s most populous region.

The Tuva reindeer quantity has fallen down to the critical level, but the population still preserves sufficient genetic diversity. Such conclusion has been made by specialists of the Vavilov Institute of General Genetics, Russian Academy of Sciences, who worked at the deer-raising farms in the Todzhinski Region, Tuva. Control over genetic markers and well thought-out breeding system will help to protect the most southern domestic reindeer population from degeneration. The researchers assessed geneti
Specialists of the Institute of Maritime Biology, Far-Easernt Branch, Russian Academy of Sciences, and Primorsky (Maritime) Production and Acclimatization Station of the Federal State Administration Primorrybvod suggest that maritime scallop should be acclimatized in low-populated waters of the Barents and White Seas. The new region suits in all respects for the Far-Eastern shellfish, which is able to feed both people and maritime inhabitants.
Northern waters of the Atlantic and P
Researchers of the Institute of Ecological Problems of the North, Ural Branch, Russian Academy of Sciences, and the Schmidt Institute of Physics of Earth, Russian Academy of Sciences, have developed technology that allows to register nanoearthquakes – seismic events of minimal possible magnitudes (-4, -5). Registration of such events allows to quickly and accurately make up seismic activity maps of small-scale territories.
Investigation of seismic activity in quiet areas (including rev
A revolutionary breath analysis machine is going on trial in a clinical environment for the first time. The invention of Professor David Smith and Professor Patrik Spanel from Keele University’s Institute for Science and Technology in Medicine, in Staffordshire, is a revolutionary technique known as SIFT-MS, which works by measuring trace gases or metabolites present in the breath.
It is so sensitive that it is capable of detecting a single molecule amid several billion molecules of air,
BIODIVERSITY of our planet is being increasingly degraded by human activity – but to what extent and at what speed?
Scientists at Manchester Metropolitan University and the Open University are taking part in the widest study yet of the impacts of nitrogen emissions from transport, industry and agriculture on plant species loss in Western Europe.
Over the next three years, research teams will set out to determine the time factor of species loss and its relationship to
Asterion Ltd (“Asterion”), a Sheffield, UK-based drug development company and part of the Biofusion portfolio, announces today that it has raised £355k to progress its novel therapies for hormone-related diseases. Biofusion plc (“Biofusion”), the University Intellectual Property (IP) commercialisation company, led the round, investing £250k. The White Rose Technology Seedcorn Fund (“WRTSF”), the venture capital fund owned by the Universities of Leeds, Sheffield and York, invested £105k. Following
Researchers of the University of Jaen, Almeria and Granada, who belong to the group “Nuevas Tecnologías aplicadas a la Investigación” (CTS-107, new technologies applied to research) led by Dr. Antonia Aránega, in collaboration with the University of Malaga, are working on the recovery of cartilaginous microlesions in elite sportspeople using adult and embryonic stem cells.
This one-year long project, called ‘Optimización de las condiciones y medios de cultivo de células madre con finalidad
An international team of astronomers released today (15 May) new results on the Cosmos, based on the largest map of the heavens ever produced.
This massive atlas emphatically confirmed recent findings that the Universe is full of ’dark energy’, a mysterious substance that makes up three-quarters of our Universe, together with ’dark matter’ which accounts for most of the remaining quarter. Understanding this composition is now one of the most important problem
In the past decade, the oyster population in New Hampshire’s Great Bay estuary has plummeted by 90 percent, due to the 1995 arrival of the oyster disease MSX. The previous century saw a slower but equally devastating demise of oysters from exuberant overharvesting. “We have seen local extinction on some reefs,” says Ray Grizzle, research associate professor at the University of New Hampshire’s Jackson Estuarine Laboratory.
Now Grizzle is working to bring oysters back to Grea
Scientists at UCSF, Celera Genomics and The Cleveland Clinic have discovered two gene variants associated with a significantly increased risk for early heart attack, or myocardial infarction (MI).
One of the genes, known as VAMP8, normally expresses a protein essential for early stages of clotting. When clotting occurs in a coronary blood vessel, it can lead to heart attack. Knowing gene mutations that increase heart attack risk can help identify people at risk and clarify molecul
Scientists have discovered that migrating dragonflies and songbirds exhibit many of the same behaviors, suggesting the rules that govern such long-distance travel may be simpler and more ancient than was once thought.
The research, published in the May 11 Biology Letters, is based on data generated by tracking 14 green darner dragonflies with radio transmitters weighing only 300 milligrams — about a third as much as a paper clip. Green darners are among the 25 to 50 species of d
Researchers from Delft University of Technology’s Kavli Institute of Nanoscience have discovered how to use the motors of biological cells in extremely small channels on a chip. Based on this, they built a transport system that uses electrical charges to direct the molecules individually. To demonstrate this, the Delft researchers sorted the individual molecules according to their color. Professor Hess of the University of Florida has called the Delft discovery “the first traffic control system in
Analysis finds statins succeed where it matters most—in improving survival
Patients who begin aggressive statin therapy while in the hospital for acute coronary syndromes (ACS) have a significantly greater chance of long-term survival, according to an analysis reported at the Society for Cardiovascular Angiography and Interventions (SCAI) 29th Annual Scientific Sessions in Chicago, May 10–13.

Plant and animal breeders have long used hybridization to transfer useful traits between species. But does the same process happen without human aid? In a new study in the June issue of American Naturalist, Kenneth D. Whitney (Indiana University and Rice University), Rebecca A. Randell (Indiana University), and Loren H. Rieseberg (Indiana University), explore how spontaneous hybridization – known as adaptive trait introgression – has a vital impact on adaptation and evolutionary diversification.
