How Tissues Could Last Forever

very excited. His ‘induced pluripotent stem cells’ (iPSC) opened the prospect for tissue regeneration without the ethical drawbacks of embryonic stem cells. In essence, Yamanaka took differentiated cells and “de-differentiated”...

Solutions Come from Freedom and Ingenuity, Not Government

...living cells use metallic cofactors, a team employed magnesium into its electrocatalyst. “This study indicates that the rational materials design can help to fabricate highly active electrocatalysts based on main...

Good Science Bears Good Fruit

...cells are inspired by nature (Phys.org). Scientists at the Norwegian Institute of Technology studied molecules in photosynthesizing plants, and created “organic” solar cells based on what they found. “The researchers...

Design Language Works in Biology

...release from North Carolina State University about the stem cells in roots. Mick Kulikowski titled his article, “‘Conductor’ Gene Found in Plant Root Stem Cell ‘Orchestra’.” The question before researchers...

Resiliency of Body Amazes Health Workers

...fall for expensive ballot initiatives, might well remember the tear-jerking commercials by Christopher Reeve hoping that embryonic stem cells would cure his paralysis that occurred when he fell off a...

Ethical Stem Cells Becoming Easier to Make and Use

Regenerative medicine is on the march, thanks to recent advances in stem cells. These are not the stem cells derived from human embryos, with all the ethical problems they entail....

Extreme Fine Tuning in Body Cells, Part 2

Here are two examples of an ultra-fine balance between function and disease inside the cells of our body’s sensory cells (Part 2). Microtubules A finely-tuned balance exists in our cells...

Extreme Fine Tuning in Body Cells, Part I

Here are two examples of an ultra-fine balance between function and disease inside the cells of our body’s sensory cells (Part 1 of 2). Hearing We learn in school how...

Words of Wisdom from Wildflowers

...conditions prevail. c. Macroscopic structures are intricate: anthers, pollen, pistils, ovules, corollae, circulatory system, colors, shapes to match insect pollinators. d. Microscopic processes are mind-boggling: DNA code, mitosis, meiosis, defense,...

More Wonders to Be Thankful For

...basis of how cells position themselves in the multicellular aggregate according to cell type. Once seen as nerve cells’ foot soldier, the axon emerges as decision-maker (Science Daily). Even cells...

Wonders of the Equipment in Your Head

...cells, in the motor cortex began to send out signals to cancel out the firing of neurons in the auditory cortex that make us aware of the sound. This process...

Stem Cells Back in the News with New Hopes and Discoveries

Scientists seem more wary about discussing embryonic stem cells than they used to be. This article never uses the term. It names them “hES” cells instead (human embryonic stem cells)...

The Frantic Determination of Some Scientists to Discover Life Elsewhere

...could organize the ingredients into cells? And what force could endow the cells with life? And could we expect undirected evolution to once again bring about anything on the level...

What Your Cells Do For You

...blood cells to seal off a wound quickly before reconstruction of the tissue begins. Scientists have found that a protein film forms rapidly over a wound as part of the...

OOL Cells Are DOA

...the Origins of Life (Astrobiology Magazine). Protein nanomachines are anything but simple. They were essential for the first living cells, but so was DNA. A cell could not survive without...
