A blood moon is coming

Posted by in categories: biotech/medical, space

On Friday 27 July there will be a total lunar eclipse, also known as a blood moon. The blood moon occurs when the sun, Earth and moon align perfectly, putting the moon in the Earth’s shadow. The red colouring is a result of sunlight refracting through the Earth’s atmosphere.

Beyond silicon: $1.5 billion U.S. program aims to spur new types of computer chips

Posted by in categories: computing, military, nanotechnology, particle physics, policy

Silicon computer chips have been on a roll for half a century, getting ever more powerful. But the pace of innovation is slowing. Today the U.S. military’s Defense Advanced Research Projects Agency (DARPA) announced dozens of new grants totaling $75 million in a program that aims to reinvigorate the chip industry with basic research into new designs and materials, such as carbon nanotubes. Over the next few years, the DARPA program, which supports both academic and industry scientists, will grow to $300 million per year up to a total of $1.5 billion over 5 years.

“It’s a critical time to do this,” says Erica Fuchs, a computer science policy expert at Carnegie Mellon University in Pittsburgh, Pennsylvania.

In 1965, Intel co-founder Gordon Moore made the observation that would become his eponymous “law”: The number of transistors on chips was doubling every 2 years, a time frame later cut to every 18 months. But the gains from miniaturizing the chips are dwindling. Today, chip speeds are stuck in place, and each new generation of chips brings only a 30% improvement in energy efficiency, says Max Shulaker, an electrical engineer at the Massachusetts Institute of Technology in Cambridge. Fabricators are approaching physical limits of silicon, says Gregory Wright, a wireless communications expert at Nokia Bell Labs in Holmdel, New Jersey. Electrons are confined to patches of silicon just 100 atoms wide, he says, forcing complex designs that prevent electrons from leaking out and causing errors. “We’re running out of room,” he says.

How giant neurons in the brain stimulate consciousness, awareness and cognition

Posted by in categories: habitats, neuroscience

A fascinating study from scientists at Rockefeller University has shed new light on a deep brain mechanism that can stimulate awareness and cognition. The research homes in on a collection of giant neurons in the brain that seem to be able to modulate stimulation of the entire central nervous system.

Mice Reprogram Gut Tissue to a Fetal State to Heal Injury

Posted by in categories: biotech/medical, genetics, life extension, neuroscience

A new study shows that mice reprogram their gut tissues to repair injury rolling them from an aged state back to a more fetal-like one.


Getting old is one thing; getting old in a healthy way is another. Many elderly people suffer from all kinds of diseases and disorders, ranging from cardiovascular problems and diabetes to Alzheimer’s and Parkinson’s disease. Wouldn’t it be nice if we could keep the body young as we grow older to prevent disease associated with old age? For instance, would it be possible to slow down or reverse the aging processes in the cells of our body?

This question has gained a lot of interest from scientists, and their research has led to the discovery of the important role that the shortening of telomeres, the protective caps on our DNA, plays in aging. While this has been described in recent posts on the LEAF blog, I would like to address another mechanism that has seen an interesting leap forward, more or less by accident: rejuvenation of tissue.

Artificial intelligence saves water for water users associations

Posted by in categories: climatology, robotics/AI, sustainability

Agriculture uses 70 percent of the water in the world, and this appears to be an upward trend regarding water needs. As the demand in other industry sectors is also increasing, and the effects of climate change exacerbate water shortages, water saving measures have become an unavoidable challenge for maintaining the sector and preserving life.

Agronomy researcher Rafael González has developed a model to predict in advance the that users will need each day. This tool came about from a drive to ally with water resource sustainability.

The model applies artificial intelligence techniques including fuzzy logic, a system used to explain the behavior of decision making. It also mixes variables that are easier to measure, like agroclimatic ones or the size of the plot of land to be watered, with other more complicated variables, like traditional methods in the area and holidays during watering season.
