Developing Cohesive, Domestic Rare Earth Element (REE) Technologies

Posted by in categories: bioengineering, biological

Program aims to fortify supply chain by utilizing bioengineering approaches to facilitate REE separation and purification.


Rare Earth Elements (REEs) are a group of 17 similar metals that are critical material components of many DoD systems, including lasers, precision-guided weapons, magnets for motors, and other devices.1 Although the U.S. has adequate domestic REE resources, its supply chain is vulnerable due to dependence on foreign entities for separation and purification of these elements. “Biomining,” an approach that uses microbes to extract or separate target metals like gold or copper from a variety of sources is not yet useful for REEs because of poor specificity and selectivity of the microbes for REEs. The Environmental Microbes as a BioEngineering Resource (EMBER) program aims to leverage advances in microbial and biomolecular engineering to develop a scalable bio-based separation and purification strategy for REEs using under-developed domestic sources.

“The EMBER program will aim to fill a critical DoD supply chain gap” stated Dr. Linda Chrisey, EMBER program manager. “The program will target the development of bioengineered organisms/biomolecular approaches for REE purification, then translate these to practical biomining modules (e.g., biosorbent, biofiltration) that can be integrated with domestic REE sources.”

Synthetic Biology Enables Microbes To Build Muscle Fibers That Are Tougher Than Kevlar

Posted by in categories: bioengineering, biological

No animals were harmed in the production of the synthetic muscle fibers, which are tougher than Kevlar.

Would you wear clothing made of muscle fibers? Use them to tie your shoes or even wear them as a belt? It may sound a bit odd, but if those fibers could endure more energy before breaking than cotton, silk, nylon, or even Kevlar, then why not?

Don’t worry, this muscle could be produced without harming a single animal.

The fungal mind: on the evidence for mushroom intelligence

Posted by in categories: biological, neuroscience

Mushrooms and other kinds of fungi are often associated with witchcraft and are the subjects of longstanding superstitions. Witches dance inside fairy rings of mushrooms according to German folklore, while a French fable warns that anyone foolish enough to step inside these ‘sorcerer’s rings’ will be cursed by enormous toads with bulging eyes. These impressions come from the poisonous and psychoactive peculiarities of some species, as well as the overnight appearance of toadstool ring-formations.

Given the magical reputation of the fungi, claiming that they might be conscious is dangerous territory for a credentialled scientist. But in recent years, a body of remarkable experiments have shown that fungi operate as individuals, engage in decision-making, are capable of learning, and possess short-term memory. These findings highlight the spectacular sensitivity of such ‘simple’ organisms, and situate the human version of the mind within a spectrum of consciousness that might well span the entire natural world.

Before we explore the evidence for fungal intelligence, we need to consider the slippery vocabulary of cognitive science. Consciousness implies awareness, evidence of which might be expressed in an organism’s responsiveness or sensitivity to its surroundings. There is an implicit hierarchy here, with consciousness present in a smaller subset of species, while sensitivity applies to every living thing. Until recently, most philosophers and scientists awarded consciousness to big-brained animals and excluded other forms of life from this honour. The problem with this favouritism, as the cognitive psychologist Arthur Reber has pointed out, is that it’s impossible to identify a threshold level of awareness or responsiveness that separates conscious animals from the unconscious. We can escape this dilemma, however, once we allow ourselves to identify different versions of consciousness across a continuum of species, from apes to amoebas. That’s not to imply that all organisms possess rich emotional lives and are capable of thinking, although fungi do appear to express the biological rudiments of these faculties.

What’s next for lab-grown human embryos?

Posted by in categories: biological, genetics

As work in real and model embryos movesforward, scientists are keen to know how similar the two really are. Finding out how models differ in their molecular details, and how their cells behave, is the main reason researchers wish to push beyond 14 days in real embryos. “We can learn a lot from a model,” says Jesse Veenvliet, a developmental biologist at the Max Planck Institute of Molecular Cell Biology and Genetics in Dresden, Germany. “But it’s important to know where it goes wrong.”


Researchers are now permitted to grow human embryos in the lab for longer than 14 days. Here’s what they could learn.

Scientists discover quantum mechanical switching in ferritin structures similar to those found in neural tissue

Posted by in categories: biological, neuroscience, particle physics, quantum physics

Quantum mechanics generally refers to the wave-like properties of things that are commonly considered to be particles, such as electrons. This article discusses evidence of a quantum mechanical switching function that is performed by strictly biological structures—ferritin protein layers that are found in cells including neural tissue.

Many scientists are investigating quantum biology, which is the application of quantum mechanics to investigate biological functions. It has recently been used to answer a number of previously unanswered questions, such as the mechanisms behind photosynthesis and the way birds can perceive magnetic fields. These quantum biological effects generally involve electrons hopping or tunneling over distances of several nanometers, behavior that is incompatible with particles but which makes sense with waves.

Synthetic biology enables microbes to build muscle

Posted by in categories: bioengineering, biological, chemistry

Would you wear clothing made of muscle fibers? Use them to tie your shoes or even wear them as a belt? It may sound a bit odd, but if those fibers could endure more energy before breaking than cotton, silk, nylon, or even Kevlar, then why not?

Don’t worry, this muscle could be produced without harming a single animal.

Researchers at the McKelvey School of Engineering at Washington University in St. Louis have developed a synthetic chemistry approach to polymerize proteins inside of engineered microbes. This enabled the microbes to produce the high molecular weight muscle protein, titin, which was then spun into fibers.

400-Million-Year-Old Fossils Reveal How the First Roots Evolved

Posted by in categories: biological, climatology, evolution, sustainability

A plant fossil from a geological formation in Scotland sheds light on the development of the earliest known form of roots. A team led by researchers at GMI – the Gregor Mendel Institute of Molecular Plant Biology of the Austrian Academy of Sciences, the University of Edinburgh, and the University of Oxford realize the first 3D reconstruction of a Devonian plant based exclusively on fossil evidence. The findings demonstrate that the appearance of different axis types at branching points resulted in the evolution complexity soon after land plants evolved sometime before 400 million years ago. The results are published in eLife.

New research demonstrates how the oldest known root axed developed more than 400 million years ago. The evolution of roots at this time was a dramatic event that impacted our planet and atmosphere and resulted in transformative ecological and climate change.

Sony’s head of AI research wants to build robots that can win a Nobel Prize

Posted by in categories: biological, robotics/AI

AI and Machine Learning systems have proven a boon to scientific research in a variety of academic fields in recent years. They’ve assisted scientists in ripe for cutting-edge treatments, of potent and, and even. Throughout this period, however, AI/ML systems have often been relegated to simply processing large data sets and performing brute force computations, not leading the research themselves.

But Dr. Hiroaki Kitano, CEO of Sony Computer Science Laboratories, “hybrid form of science that shall bring systems biology and other sciences into the next stage,” by creating an AI that’s just as capable as today’s top scientific minds. To do so, Kitano seeks to launch the and.

“The distinct characteristic of this challenge is to field the system into an open-ended domain to explore significant discoveries rather than rediscovering what we already know or trying to mimic speculated human thought processes,” Kitano. “The vision is to reformulate scientific discovery itself and to create an alternative form of scientific discovery.”

Trapped-ion crystal makes an ultra-precise quantum sensor

Posted by in categories: biological, cosmology, quantum physics

Physics World


An ultra-precise quantum sensor based on trapped beryllium ions is up to 20 times better at detecting weak electric fields than previous atomic devices. By introducing entanglement between the collective motion of the ions and their electronic spin, a collaboration led by the US National Institute of Standards and Technology (NIST) demonstrated that the ion displacement sensitivity in the presence of an electric field was an order of magnitude greater than for classical protocols with trapped ions. With further improvements, the technology could even be used in the search for dark matter.

Quantum sensors can detect and measure signals that are undetectable with their classical counterparts. They are thus a promising tool in many areas of fundamental science, including biological imaging as well as physics. Of the many different systems being pursued as quantum sensors, trapped ions could be particularly favourable due to experimenters’ precise control over their parameters and their ability to introduce entanglement into the system.
