Combating Antibiotic-Resistant Bacteria — Dr. Erin Duffy, Ph.D., Chief of Research & Development, and Kevin Outterson, ESQ., Executive Director, CARB-X.

The Combating Antibiotic-Resistant Bacteria Biopharmaceutical Accelerator (CARB-X — https://carb-x.org/) is a global non-profit partnership accelerating antibacterial products to address drug-resistant bacteria, a leading cause of death around the world. 1.27 million deaths worldwide were attributed to resistant bacterial infections in 2019.

Targeting Root Causes Of Diseases And Aging — Dr. Andrew Adams, Ph.D., Vice President, Neurodegeneration Research; Co-Director, Lilly Institute for Genetic Medicine, Eli Lilly.

Dr. Andrew Adams, Ph.D. is Vice President of Neurodegeneration Research at Eli Lilly (https://www.lilly.com/) and Co-Director of their new Lilly Institute for Genetic Medicine (https://lilly.mediaroom.com/2022-02-22-Lilly-Announc…ort-Site), a $700 million initiative to establish an institute for researching and developing genetic medicines, specifically acting at the nucleic acid level, to advance an entirely new drug class that target the root cause of diseases, an approach that is fundamentally different than medicines available today.

Deep learning–based language models, such as BERT, T5, XLNet and GPT, are promising for analyzing speech and texts. In recent years, however, they have also been applied in the fields of biomedicine and biotechnology to study genetic codes and proteins.

Circa 2021

As described above, molecular therapeutics enabling expression of a truncated dystrophin have been far developed. However, an unprecedented opportunity to correct the disease-causing mutation has arisen with the advent of Crispr-Cas9 technology (Fig. 1).

Since the generation of a Cas9-transgenic mouse [28], which allowed for pinpoint gene alterations specifically in organs targeted by AAVs encoding for the corresponding guide RNAs (gRNAs), it became clear that the inevitable course of inherited diseases might be altered by Cas9-mediated correction. Although certain limitations were unmasked early on, such as the preference of non-homologous end-joining (NHEJ) over homology-directed repair (HDR) upon enzymatic cleavage of the double stranded DNA by Cas9, or the packaging capacity of AAVs, muscular dystrophies seemed an ideal target for genome editing. DMD mutations inducing Duchenne muscular dystrophy (DMD) seemed particularly well suited, since internal truncations of the protein may lead to a shortened but stable protein with partial functional restitution and a milder disease progression, as seen in the allelic Becker muscular dystrophy (BMD).

Death Valley brings the heat, but there are other hot spots on this sweltering planet.

Summers can be hot in Death Valley, California. In fact, it is likely the hottest place on Earth—ever. Especially on Sunday, August 16 and—again—on June 17, 2021. The mercury spiked to a sweltering 130 degrees Fahrenheit in the national park, drawing crowds of tourists who flocked to take pictures with the park’s digital thermometer.

The brain is inarguably the single most important organ in the human body. It controls how we move, react, think and feel, and enables us to have complex emotions and memories. The brain is composed of approximately 86 billion neurons that form a complex network. These neurons receive, process, and transfer information using chemical and electrical signals.

Learning how neurons respond to different signals can further the understanding of cognition and development and improve the management of disorders of the brain. But experimentally studying neuronal networks is a complex and occasionally invasive procedure. Mathematical models provide a non-invasive means to accomplish the task of understanding neuronal networks, but most current models are either too computationally intensive, or they cannot adequately simulate the different types of complex neuronal responses. In a recent study, published in Nonlinear Theory and Its Applications, IEICE, a research team led by Prof. Tohru Ikeguchi of Tokyo University of Science, has analyzed some of the complex responses of neurons in a computationally simple neuron model, the Izhikevich neuron model.

“My laboratory is engaged in research on neuroscience and this study analyzes the basic mathematical properties of a neuron model. While we analyzed a single neuron model in this study, this model is often used in computational neuroscience, and not all of its properties have been clarified. Our study fills that gap,” explains Prof. Ikeguchi. The research team also comprised Mr. Yota Tsukamoto and Ph.D. student Ms. Honami Tsushima, also from Tokyo University of Science.

Imagine a future in which you could 3D-print an entire robot or stretchy, electronic medical device with the press of a button—no tedious hours spent assembling parts by hand.

That possibility may be closer than ever thanks to a recent advancement in 3D-printing technology led by engineers at CU Boulder. In a new study, the team lays out a strategy for using currently-available printers to create materials that meld solid and liquid components—a tricky feat if you don’t want your robot to collapse.

“I think there’s a future where we could, for example, fabricate a complete system like a robot using this process,” said Robert MacCurdy, senior author of the study and assistant professor in the Paul M. Rady Department of Mechanical Engineering.

Summary: The Izhikevich neuron model allows the simulation of both periodic and quasi-periodic responses in neurons at lower computational cost.

You read that right, a hologram doctor.

It’s not science fiction: Hologram doctors beamed to space to visit astronauts.

In 2021, a team of hologram doctors was “holoported” to space to visit astronauts living aboard the International Space Station, NASA has revealed in a new post. The hologram teams, led by NASA flight surgeon Dr. Josef Schmid and Fernando De La Peña Llaca, CEO of software provider Aexa Aerospace, were the first humans to ever be “holoported” from Earth to space.
