Diblock copolymer micellar nanoparticles decorated with annexin-A5 proteins

One of the banes of modern cancer therapy is that clinicians and patients must often wait months before they can tell if a given treatment is working.

Self-illuminating quantum dots for in vivo imaging

Quantum dots have already proven themselves as powerful imaging probes that can enable researchers to track disease-related molecules inside cells and even within the body.

Scientists develop piezoresponse force microscopy

A seminal early event in the history of nanotechnology was the development of the atomic force microscope (AFM), which used a nanoscale cantilever to image solid materials at the atomic level.

Human hair follicles found to be a new source of adult stem cells

Researchers at the University of Pennsylvania School of Medicine have isolated a new source of adult stem cells that appear to have the potential to differentiate into several cell types.

World-first stem cell research may help male infertility

Scientists have shown for the first time that sperm grown from embryonic stem cells can be used to produce offspring.

Mice sperm grown in a lab produces baby mice

In ground breaking research scientists have for the first time produced mice using sperm grown in the laboratory from embryonic stem cells.

How the brain rewires after lesions

Scientists from Bochum investigate the reorganizational capacity of the adult brain.

New polymer-lipid hybrid nanoparticle

A novel combination of lipids, a negatively charged polymer, and the anticancer drug doxorubicin has yielded a new nanoparticle that can kill breast cancer cells that are normally resistant to this drug.

Buckyballs deliver multiple drugs simultaneously to tumors

Combining a monoclonal antibody known to target melanoma tumors with multiple C60 buckyballs, researchers at Rice University and the University of Texas M. D. Anderson Cancer Center have developed a new way to deliver multiple drugs simultaneously to tumors.

Fly research sheds light on sleep regulation and its role in memory

Researchers at the University of Pennsylvania School of Medicine have discovered that a brain region previously known for its role in learning and memory also serves as the location of sleep regulation in fruit flies.

Scientists watch the behavior of a single gene in real time

Scientists at the Albert Einstein College of Medicine of Yeshiva University have observed for the first time that gene expression can occur in the form of discrete "pulses" of gene activity.

Scientists reveal two paths of neurodegeneration

Wiring the developing brain is like creating a topiary garden. Shrubs don't automatically assume the shape of ornamental elephants, and neither do immature nerve cells immediately recognize the "right" target cell.

Research explains how pathogenic bacteria evolved over millions of years

Bacteria like Salmonella have a complicated immune system that helps them recognize and isolate foreign DNA trying to invade their cell membrane, according to a University of Washington-led study in the June 8 issue of Science Express.

Scientists describe elaborate system of gene control triggered by chemical damage to DNA

Scientists describe for the first time a web of inter-related responses that cells use to avoid becoming diseased or cancerous after being exposed to a powerful mutagen.

Humans are a cocktail of bacteria and human cells

Gene experts after studying the DNA of hundreds of different kinds of bacteria in the human gut have reached the conclusion that the human race may not be quite as human as we may think.
