Better understanding of membrane fusion

Cells constantly swap cargo bound in vesicles, miniscule membrane-enclosed packages of proteins and other chemicals. Before the swap can take place, the vesicle membrane must fuse with another membrane, creating channels packages can pass through.

Mapping rhesus macaque genome helps illuminate what makes us human

Researchers have sequenced the genome of the relatively ancient rhesus macaque ( Macaca mulatta ), providing perspective into how humans are genetically different from our primate relatives.

New device to test for proteins that play important role in human health and disease

A new technology developed at the University of Toronto is revealing biochemical processes responsible for diseases such as cystic fibrosis and could one day pave the way for pharmaceutical applications.

Macaque genome analysis will improve scientists' ability to identify human genes involved in diseases

Cornell experts in computational biology and bioinformatics have made key contributions to the analysis of the genome of the rhesus macaque, better known as the rhesus monkey.

Bacteria can barge inside immune cells

Immune cells that are the body's front-line defense don't necessarily rest quietly until invading bacteria lock onto receptors on their outside skins and rouse them to action, as previously thought. In a new paper, University of Michigan scientists describe their findings that bacteria can barge inside these guard cells and independently initiate a powerful immune response.

Scientists discover key player in embryonic muscle development

Muscle fibers are large cells that contain many nuclei. They begin, like all animal cells, as naive embryonic cells. These cells differentiate, producing intermediate cells called myoblasts that are now destined to become muscle.

Analysis of Rhesus monkey genome provides new clues to primate biology

An international consortium of researchers has published the genome sequence of the rhesus macaque monkey and aligned it with the chimpanzee and human genomes.

How size matters in the retention of nanomaterials in tissue

Tiny, biodegradable particles filled with medicine may also contain answers to some of the biggest human health problems, including cancer and tuberculosis.

Antibiotic stress, genetic response and altered permeability of E. coli

Bacterial infections caused by Gram-negative bacteria such as Escherichia coli are frequently resistant to two or more antibiotics (multi-drug resistant).

One cornea can treat three persons' eye disease

A new study from India has found that one donated cornea may have the potential to treat three people with eye damage or disease.

One donor cornea may be divided and transplanted into multiple patients with eye disease

Recent developments have allowed ophthalmologic surgeons to move from transplanting the entire cornea in every patient to more focused operations that involve removing and replacing only the diseased or damaged portion of the cornea.

New regulatory mechanism for critical protein signaling domain

The study is being published in Science Express, an advanced online edition of the journal Science, on April 5. It will appear in the print version of Science later this spring.

Scientists solve puzzle of osteoclasts

Breaking down bone is a tough job. Yet, our bones undergo remodeling every day of our lives, as old material is cleared away so that new bone can form.

Polymers show promise for gene delivery

Virginia Tech polymer scientists have developed a new family of gene vectors , novel polymers that can ferry genetic material across the cell membrane so that it can be incorporated into the machinery of the cell.

New understanding of the mechanics of hearing

Modern hearing aids, though quite sophisticated, still do not faithfully reproduce sound as hearing people perceive it.

Breast-feeding exclusively lowers risk of vertical HIV transmission to children in developing countries

HIV-positive women in developing countries could reduce the risk of transmitting the virus to their infants if they exclusively breast-feed rather than supplement breast milk with formula, animal milk or solid food, according to a study published in the March 31 edition of the Lancet, Reuters reports.

Scientists uncover bacterial cloaking

Scientists have uncovered the workings of a method bacteria responsible for diseases such as meningitis and blood disorders use to hide from the body's immune system.

Breastfeeding significantly reduces risk of HIV transmission from mother to child

A study by scientists at the Africa Centre for Health and Population Studies, South Africa, has shown that exclusive breastfeeding can significantly reduce the risk of HIV transmission from mother to child in infants aged under six months when compared to those also given solid foods or replacement feed (i.e. formula milk).

Scientists create small molecules to probe proteins deep inside cell membrane

Proteins, which form much of the molecular machinery required for life, are the targets of most drug molecules.

Iron nanoparticles exhibit toxic effects on neuronal cells

Researchers at UC San Diego have discovered that iron-containing nanoparticles being tested for use in several biomedical applications can be toxic to nerve cells and interfere with the formation of their signal-transmitting extensions.
