Critical migrating neurons in the human brain decline during infancy

José Manuel García Verdugo, full professor of Cell Biology at University of Valencia, together with a University of California research team, has participated in the discovery of new pathways of neurons migrating from lateral ventricles to the prefrontal cortex. The work done in chidren at early ages reveals a new cell pathway which may increase the amount of neurons in regions important for cognitive tasks, emotional processes and spatial perception.

Electron-beam sterilized dialysis membrane may increase risk of thrombocytopenia

Patients who had undergone hemodialysis using dialyzers that had been sterilized with the use of electron beams were more likely to develop thrombocytopenia, according to a study in the October 19 issue of JAMA.

New book investigates what fuels the passion for science

On April 8, 1982, alone in a laboratory, chemist Dan Shechtman looked through an electron microscope and saw an impossible pattern. He had discovered quasicrystals. But his groundbreaking findings were rejected, even mocked, by the scientific establishment for years.

Insight into how powerful anti-HIV antibody grabs hold of the virus

Researchers at The Scripps Research Institute have uncovered the surprising details of how a powerful anti-HIV antibody grabs hold of the virus. The findings, published in Science Express on October 13, 2011, highlight a major vulnerability of HIV and suggest a new target for vaccine development.

Microscopy with helium ions may greatly enhance both surface and sub-cellular imaging

The ability to obtain an accurate three-dimensional image of an intact cell is critical for unraveling the mysteries of cellular structure and function. However, for many years, tiny structures buried deep inside cells have been practically invisible to scientists due to a lack of microscopic techniques that achieve adequate resolution at the cell surface and through the entire depth of the cell.

Two ACS members, editor of JACS to receive nation's highest honors in science and innovation

Peter J. Stang, Ph.D., editor of the Journal of the American Chemical Society (JACS), and American Chemical Society members Jacqueline K. Barton, Ph.D. and Rakesh Agrawal, Ph.D., are among 12 eminent researchers and inventors named by President Obama to receive the nation's highest honors in science and innovation.

Three papers reveal structure and workings of G protein-coupled receptors

Three international teams of scientists, led by researchers at the University of California San Diego, University of Michigan and Stanford University, have published a trio of papers describing in unprecedented detail the structure and workings of G protein-coupled receptors (GPCRs), a large family of human proteins that are the target of one-third to one-half of modern drugs.

Study examines effects of carbon nanoparticles on living cells

A study by researchers from the schools of science and medicine at Indiana University-Purdue University Indianapolis examines the effects of carbon nanoparticles (CNPs) on living cells. This work is among the first to study concentrations of these tiny particles that are low enough to mimic the actual exposure of an ordinary individual.

Electron microscope reveals minute morphology of dendritic trees

Neurons in the brain play a role as an electric wire conveying an electrical signal. Because this electric wire is connected with various joints, various brain functions can occur. A neuron which has dendritic trees on it, receives the signals with many synapses located on those dendritic trees, and carries out functions by combining the received signals.

IBN scientists harness ultrasmall peptides to repair spinal disc damage

New ultrasmall peptides that can be used as building blocks for a wide range of regenerative applications such as spinal disc replacement and cartilage repair have been developed by scientists at the Institute of Bioengineering and Nanotechnology (IBN), the world's first bioengineering and nanotechnology research institute. These peptides spontaneously assemble in water to form hydrogels, which resemble collagen, a major component of connective tissues found in cartilage, ligaments, tendons, bone and skin.

Scientists invent new system that uses magnetism to purify hybrid nanoparticles

A team of Penn State University scientists has invented a new system that uses magnetism to purify hybrid nanoparticles -- structures that are composed of two or more kinds of materials in an extremely small particle that is visible only with an electron microscope.

AMA releases new Current Procedural Terminology codes

Friday September 2, 2011 the AMA released new Current Procedural Terminology (CPT) codes that will be reported by hospitals, physicians and ambulatory centers providing coverage for additional treatment options for cancer patients.

Discovery in rare disease may shed light on common causes of blindness

In a rare eye disease, the retina degenerates because light-receiving cells fail to regenerate, research led by a student at Case Western Reserve University School of Medicine shows.

Study reveals structure of ribosomal assembly intermediate

As part of a joint research effort with the University of Michigan, scientists from the Florida campus of The Scripps Research Institute have for the first time defined the structure of one of the cell's most basic engines, which is required for cell growth, as it assembles from its components.

Flatworms provide new insight into organ regeneration, evolution of mammalian kidneys

Our bodies are perfectly capable of renewing billions of cells every day but fail miserably when it comes to replacing damaged organs such as kidneys. Using the flatworm Schmidtea mediterranea-famous for its capacity to regrow complete animals from minuscule flecks of tissue-as an eloquent example, researchers at the Stowers Institute for Medical Research demonstrated how our distant evolutionary cousins regenerate their excretory systems from scratch.

New insights into cancer-induced intussusceptive angiogenesis

Researchers have gained a new understanding of the way in which growing tumors are fed and how this growth can be slowed via angiogenesis inhibitors that eliminate the blood supply to tumors. This represents a step forward towards developing new anti-cancer drug therapies.
