The U.S. Department of Agriculture's (USDA) Animal and Plant Health Inspection Service (APHIS) announced approval of the first two nonbrowning apple varieties, Arctic Golden and Arctic Granny apples. 

An estimated 285 million people are visually impaired worldwide and age-related macular degeneration alone is the leading cause of blindness among older adults. There may be some new hope, in the form of prototype telescopic contact lenses. 

Eric Tremblay from EPFL in Switzerland says the first iteration of the telescopic contact lens--which magnifies 2.8 times--was announced in 2013. Since then the scientists behind the DARPA-funded project have been fine-tuning the lens membranes and developing accessories to make the eyewear smarter and more comfortable for longer periods of time, and thus more usable in every day life.

Known as the ‘Heart of Voh’ for its proximity to the Voh commune, a mining colony controlled by the French, these Mangrove swamps along the coast of New Caledonia in the southwest Pacific Ocean formed this natural structure, caused by changes in vegetation cover. Photographer Yann Arthus-Bertrand made it famous by using a photograph of the heart on the cover of a book, The Earth from the Air.

This false-color satellite image of the heart-shaped formation was captured by the Korea Aerospace Research Institute’s Kompsat-2 satellite on 1 April 2009.  No undead lichs had to be sent to their final resting place to obtain it. 

Despite the claims of people selling books on ascension into being robots or diet fads, you are not going to live forever.

It used to be life was truly short and now we are in a period where life is much longer but after the age of 65 it is not better, it is instead a slow steady decline toward death.

The goal cannot be to try and live forever, nature has built in too many biological landmines to control that, but to live healthier until we do die. First, we'd have to agree on what this 'successful' aging would look like, without wellness psychobabble.

I’ll demonstrate how to build a simple magnetic optical mount for a cat toy (laser pointer). Though it is simple—that is, there aren’t any fine tuning mechanisms one would find on an optical bench—it is, nonetheless, inexpensive and flexible enough to use for simple optical experiments such as demonstrating the Tyndall effect, .

I used a magnetic chip clip to clamp the laser pointer switch (a press switch) in the on position and attach the laser pointer to the Erector set mount.

Relationships are often interpreted as the outcome of an exchange of goods and services.

Common knowledge says that the sexes want different things from a partner.

These preferences are often reduced to shallow, one-dimensional demands – beauty for men and resources for women. “Opposites attract,” they say. No one asks, “Why did that beautiful, young woman marry that old, old man?” because they already know the answer. He had something she wanted and she had something he wanted.

Researchers have discovered a molecular ‘switch’ that controls replication and transcription of mitochondria DNA, a key finding that could influence the development of targeted therapies for cancer, developmental processes related to fertility and aging. 

Mitochondria are organelles located outside the nucleus of nearly every cell in humans. While most of the cell’s DNA is inside the nucleus, mitochondria maintain their own DNA and contribute a small number of genes that are essential for cellular respiration and energy generation.

Bits of the self have historically been un memoire emotional aides. Cristiana Gasparotto

As Valentine’s Day approaches, many of us will think about sharing a token of our affection.

The ubiquitous card is often teamed with a staple of the season: chocolate, perfume or flowers. These gifts have become accepted expressions of romantic love in Western cultures and yet they often fail to embody a real emotional connection between the giver and recipient.

I read a sad story in the news recently. A Baltimore mother died a week after giving birth to two twin sons, leaving her husband to raise the two boys on his own. 

As tragic as the news was, the reason that it made national headlines was that the mother was 56 years old. Initial reports indicate that her death was the result of a bowel obstruction, not because of the pregnancy, but a lot of the coverage of this story has focused on one question: how old is too old to give birth?

Extreme mechano-sensitive neurons of tactile-foraging ducks fit the bill for touch research.

When we reach out to touch something, our nervous system converts the mechanical input from our fingers contacting an object into an electrical signal in the brain. The process, known as mechanosensation, is one of our fundamental physiological processes, on par with sight and smell. But how it works on a cellular level remains poorly understood, holding back development of effective treatments for mechanosensory disorders like chronic pain.

Now, a team of researchers from the Yale University School of Medicine has identified a new model organism that may help elucidate the cellular mechanisms behind mechanosensation: the ordinary duck.
