Big Science: Lean to the Left

...even after birth in some cases, and expect taxpayers to pay for it. Additionally, they want no restrictions on the use of aborted human tissue and embryonic stem cells for...

Blood Cells Act as Multi-Purpose Truckers

tissues where they differentiate into macrophages (cells that engulf and destroy pathogens and apoptotic cells) or dendritic cells (cells that process antigen material and present it on the cell surface...

Our Senses Did Not Evolve

...cochlear outer hair cells (PNAS). This Darwin-free research paper describes wonders in the inner ear, and how failure of particular links between hair cells can lead to deafness. The fine-tuning...

Research on Embryonic Stem Cells Takes Dangerous Turns

...respect. Embryonic Stem Cells: Pushing the Ethical Envelope It’s been awhile since we reported on embryonic stem cells (ESC). Unlike adult stem cells (ASC) and induced pluripotent stem cells (iPSC),...

Epigenetics Complicates Evolutionary Theory

...Epigenetics). The same stem cells in bone marrow differentiate into red blood cells (RBCs, also called erythrocytes), white blood cells, and platelets. How does that happen? Before looking into the...

Botanical Marvels: How Plants Catch Light and Take Flight

...on Earth.” How Plants Stay Young At the tip of a plant stem, and along points where branches develop, there are clusters of stem cells. When these stem cells divide,...

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

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
