New model gives hands-on help for learning the secrets of molecules

New model gives hands-on help for learning the secrets of molecules
2012-08-24
(Press-News.org) For biology researchers, the complex world of molecular proteins – where tens of thousands of atoms can comprise a single protein – may be getting clearer with the help of a new soft, transparent, and squishy silicone model they can hold in their hands. Its advantage over traditional computer and solid models is that it is mostly transparent and easy to manipulate, which will help researchers more intuitively understand protein structures, positions, and interactions. The models will enable researchers to quickly and collaboratively see, touch, and test ideas about molecular interactions and the behavior of proteins. These insights are keys to innovation in drug design because they help generate discussion about what a particular molecular surface might be like and how a protein is shaped and structured. The models also allow researchers to simulate docking maneuvers involving molecules known as ligands and their partners, a chemical binding step that can turn a biological process on or off.

This boost to molecular modeling comes from Masaru Kawakami, Ph.D., a biophysicist researcher at JAIST (Japan Advanced Institute of Science and Technology) in Ishikawa, Japan. It appears in the current issue of the American Institute of Physics (AIP) journal Review of Scientific Instruments. "Because my new model is soft, users can deform the model and experience ligand binding or protein-protein association, which has never been possible with other physical molecule models", said Kawakami. "I believe my model would be an effective discussion tool for the classroom or laboratory to stimulate inspired learning."

Article: "A soft and transparent handleable protein model" is published in Review of Scientific Instruments.

Modeling metastasis

Modeling metastasis
2012-08-24
Cancer metastasis, the escape and spread of primary tumor cells, is a common cause of cancer-related deaths. But metastasis remains poorly understood. Studies indicate that when a primary tumor breaks through a blood vessel wall, blood's "stickiness" tears off tumor cells the way a piece of tape tears wrapping paper. Until now, no one knew the physical forces involved in this process, the first step in metastasis. Using a statistical technique employed by animators, scientists created a new computer simulation that reveals how cancer cells enter the bloodstream. The researchers ...

The end of an era? Branding horses does not enable them to be identified

2012-08-24
There are many reasons why it is important to be able to identify farm animals, horses and small companion animals. Unique identification marks are essential for ensuring the correctness of breeding programmes, for preventing the spread of disease and for eliminating the possibility of deceit in competitions or when animals are sold. The traditional method of marking larger farm animals relies on branding with hot irons or on ear-tagging but this is deemed inappropriate for use on dogs and cats, which are identified by the implant of a microchip transponder. Until recently, ...

Astrocytes control the generation of new neurons from neural stem cells

Astrocytes control the generation of new neurons from neural stem cells
2012-08-24
Astrocytes are cells that have many functions in the central nervous system, such as the control of neuronal synapses, blood flow, or the brain's response to neurotrauma or stroke. Reduces brain tissue damage Prof. Pekny's laboratory together with collaborators have earlier demonstrated that astrocytes reduce the brain tissue damage after stroke and that the integration of transplanted neural stem cells can be largely improved by modulating the activity of astrocytes. Generation of new neurons In their current study, the Sahlgrenska Academy researchers show how astrocytes ...

Researchers describe new molecular interactions behind the inhibition of TGF beta-signaling

2012-08-24
This press release is available in Spanish. Researchers headed by Maria Macias an ICREA researcher at the Institute for Research in Biomedicine (IRB Barcelona) and Joan Massagué, a Howard Hughes Medical Institute investigator at Memorial Sloan-Kettering Cancer Center (MSKCC) in New York, have identified a new molecular mechanism that plays a crucial role in the control of the activation of certain genes associated with cancer. Through detailed structural and biochemical studies, the researchers identified a key domain present in a family of proteins called Smads, whose ...

Southampton physicists join search for hidden magnetic states

Southampton physicists join search for hidden magnetic states
2012-08-24
Physicists from the University of Southampton were among the first researchers to use the new high magnetic-field beamline at Diamond Light Source, the UK's national synchrotron facility, to search for 'hidden magnetic states'. If found, they will provide important confirmation of a theoretical model, which could have important applications in magnetic data storage. Diamond's new I10 Beamline for Advanced Dichroism Experiments (BLADE) beamline, which has 300,000 times the strength of the earth's magnetic field, is providing them with the tools for the search. The beamline ...

Working class prefers comedy and the intellectual class goes for drama

Working class prefers comedy and the intellectual class goes for drama
2012-08-24
A study enjoying Spanish participation has analysed the theatre demand of society according to the socioeconomic status of the different types of the viewing public. The results were that the theatre is not just enjoyed by the intellectual classes. While they do prefer drama, the working class opts for comedy and the wealthier are swayed by reviews. Theatre arts are loss-making services that require subsidies to stay afloat. This type of practice has frequently come under fire as it is thought that theatre is consumed mainly by society's economic elite. A study published ...

NASA spots heavy rainfall in Tropical Storm Isaac

NASA spots heavy rainfall in Tropical Storm Isaac
2012-08-24
NASA's Tropical Rainfall Measuring Mission satellite, known as TRMM has been monitoring the rainfall rates within Tropical Storm Isaac as the storm entered the eastern Caribbean Sea. After becoming a tropical storm in the central Atlantic on August 21, Isaac continued tracking westward and entered the eastern Caribbean early on the evening of Aug. 22 with the ill-defined center passing just south of Guadeloupe in the Leeward Islands. Since becoming a tropical storm, Isaac has shown little change in intensity, but the National Hurricane Center expects that to change ...

Tropical Storm Tembin crossed over Taiwan, back over water

Tropical Storm Tembin crossed over Taiwan, back over water
2012-08-24
NASA's Aqua satellite captured an image of Tropical Storm Tembin after it made a quick track across southern Taiwan and re-emerged over the open waters of the Philippine Sea. On Aug. 24 at 05:15 UTC (12:15 a.m. EDT), NASA's Aqua satellite flew over Tropical Storm Tembin and the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument captured a visible image of the storm after it had crossed southern Taiwan and re-emerged into the waters of the Philippine Sea. After Tembin interacted with the land, the storm's eye was no longer visible. The storm has also become ...

Native plants in urban yards offer birds 'mini-refuges'

Native plants in urban yards offer birds mini-refuges
2012-08-24
Yards with plants that mimic native vegetation offer birds "mini-refuges" and help to offset losses of biodiversity in cities, according to results of a study published today in the journal PLOS ONE. "Native" yards support birds better than those with traditional grass lawns and non-native plantings. Researchers conducted the study through the National Science Foundation's (NSF) Central Arizona-Phoenix Long-Term Ecological Research (LTER) site, one of 26 such sites around the globe in ecosystems from coral reefs to deserts, from forests to grasslands. "To a desert ...

Regina, August 15, 2012 – Only two per cent of Canadians believe climate change is not occurring, a new important survey released today by IPAC-CO2 Research Inc. concluded. The survey comes on the heels of Alberta Premier Alison Redford's recent push for ...
