Newly discovered molecule could deliver drugs to treat diseases

Kansas State University researchers have designed molecules that may be capable of delivering drugs inside the body. For the first time, researchers have created membrane-bound vesicles formed entirely of polypeptides. The vesicles could serve as a new drug delivery system to safely treat cancers and neurodegenerative diseases.

Bone grown from human embryonic stem cells

Researchers at the New York Stem Cell Foundation Laboratory have grown bone grafts from human embryonic stem cells for use in research and potential therapeutic application. This is the first example of deriving bone cell progenitors from human embryonic stem cells in large quantities for repair of centimeter-sized defects.

First gene therapy successful against aging-associated decline: Mouse lifespan extended up to 24% with a single treatment

Inducing cells to express telomerase, the enzyme which extends the telomeres (ends of linear chromosomes) also extends the lifespan of mice. This study shows that life extension is actually a doable thing and could improve the health span of us!

Many studies have shown that you can increase lifespan of many species, including mammals, by acting on specific genes, but that usually involves altering genes in embryos. Not something to be done with humans.

The genes behind human intelligence also made us vulnerable to autism

While the genetic cause(s) of autism are still mostly unknown, the most common single-gene cause is Fragile X Syndrome. Fragile X Syndrome accounts for 5% of autism cases and involves errors on the X chromosome that disrupt normal brain development.

Fragile X Syndrome prevents the production of FMRP, an important brain protein needed to activate the NOS1 gene. The NOS1 gene product is found throughout the developing human brain, especially in guiding the maturation of the speech, language, and decision-making centers.

Kansas State University biologist seeks to understand the world's flora

Since the time of Darwin, biologists have sought to understand the evolution of plant species. Joseph Craine, grassland ecologist and research assistant professor of biology at Kansas State University, publishes "Resource Strategies of Wild Plants" in his ongoing work to understand how ecological forces have shaped the world's flora.

Bright future for alternative energy with greener solar cells

Research at Kansas State University's Department of Chemistry is improving dye-sensitized solar cells. This type of solar cell uses a dye to help generate energy from sunlight. By creating a less toxic dye and combining it with a bacteria, the solar cells are less toxic to the environment and living organisms.

Plant diversity is key to maintaining productive vegetation

Plant diversity yields higher productivity in prairie and forest stands. Every additional species in a plot contributed to an increase in soil fertility and biomass production over a 14-year period.

While the research study used long-lived prairie plants, it also is a model system for all vegetation, whether prairie, forest, or row crop.

Drug-Resistant Bacteria Found in 4-Million-Year-Old Cave

"Deep in the bowels of a pristine New Mexico cave, microbiologists have discovered nearly a hundred types of bacteria that can fight off modern antibiotic drugs."

Even though they have been isolated thousands of feet below the Earth's surface for millions of years, these bacteria exhibit resistance to antibiotic drugs, even newer, synthetic derivatives.

The discovery serves as an intriguing lead in the quest to understand how drug-resistant diseases emerge. It is now hypothesized that "drug resistance" genes may have evolved millions of years ago to confer resistance to other, naturally occurring substances.

How to use vegetables as mood lighting

Pickle, the perfect condiment and accent light! Some cool physics explains how this humble side-dish also conducts electrons and generates light.

Meteorites reveal another way to make life's components

Some of the simplest building blocks of life, amino acids used to build proteins, can be made chemically in space with no living cells involved. Originally thought to only occur in low-temperature chemical reactions, scientists at NASA have shown that the same building blocks can be made under high temperature conditions.

Fanciful photos reveal the whimsical secret lives of ants

Andrey Pavlov's photographs imagine how ants might spend their free time, in lightly fantastical scenes. Although his photos are obviously staged, he uses real ants.

Effects of environmental toxicants reach down through generations

A Washington State University researcher has shown that a variety of chemicals have negative effects on the exposed animal and the next 3 generations of its offspring. That's right, the great-grandchildren still are affected.

While the lettering of the DNA sequence is unchanged, modifications to the nucleic acid letters (nucleotides) affect how the gene is turned on or off.
