This year’s election of new members to the American Academy of Arts and Sciences maintains a commitment to honoring excellence that began more than 240 years ago. In 1780, the Academy’s founders – including John Adams and John Hancock – envisioned an organization that would recognize accomplished individuals and engage them in addressing the greatest challenges facing the young nation. The first members elected to the Academy in 1781 included Benjamin Franklin and George Washington.
Today, the Academy continues to be both an honorary society, electing new members from the non-profit, private, and public sectors, and an independent policy organization with initiatives in the arts, democracy, education, global affairs, and science.
When announcing this year’s new members, Academy President David W. Oxtoby said, “With the election of these members, the Academy is honoring excellence, innovation, and leadership and recognizing a broad array of stellar accomplishments. We hope every new member celebrates this achievement and joins our work advancing the common good.”
The nearly 270 members elected in 2023 are drawn from academia, the arts, industry, policy, research, and science, and include more than 40 International Honorary Members (IHM) from 23 countries.

Screening Against Pathological Neuronal Firing
Phenotypic screening using stem cell-derived human cells is a powerful new tool for drug discovery. By simultaneously measuring the effects of thousands of compounds on disease-specific cellular phenotypes, such as cell death or axon degeneration, we can discover new targets through the screening compounds’ known biological activities and use this as a start to introduce new treatments. In many neurological disorders, neuronal excitability is altered and contributes to disease onset and progression. If a new screening platform can be designed to measure neuronal excitability in a high-throughput manner, we can then expand the drug development process to discover ways to reverse such pathological phenotypes.

Disease Characteristics of Dopaminergic Neurons in Neurodevelopmental and Neuropsychiatric Disorders
Maria Sundberg shares new research from the lab of Mustafa Sahin on the role of a small piece of chromosome 16, called the 16p11.2 locus, in disease phenotypes of dopaminergic neurons. The team identified that RhoA pathway activation led to network dysfunction in 16p11.2 deletion neurons. Its inhibitor, Rhosin, rescued the hyperactivity of these neuronal networks. In the future, the RhoA pathway and its inhibitors may serve as potential therapeutic targets.

The Brain’s Wiring Technicians
From the bark of a puppy to the patter of rain against the window, our brains receive countless signals every second. Most of the time, we tune out inconsequential cues—the buzz of a fly, the soft rustle of leaves in the tree—and pay attention to important ones—the sound of a car horn, a bang on the door. This allows us to function, navigate and, indeed, survive in the world around us.

Awakening a Dormant Drive
The drives to eat, drink, and sleep are with us from birth until death. The motivation to mate stands apart in that it emerges later in life. This is true in many animals, including flies. Where does mating drive come from? Is it generated by new wiring, or was it there all along, lying dormant? While neuroscience has long assumed the former, we find evidence for the latter.

A Case of Mistaken Identity Leads to the Discovery of a Potent Agent for CNS Repair
The optic nerve conveys visual information from the eye to the brain. Unfortunately, like other pathways in the central nervous system (CNS), the optic nerve cannot regenerate when injured, resulting in lifelong blindness for victims of traumatic or ischemic damage to this pathway or in degenerative diseases such as glaucoma. Over the past 20 years or so, our lab and others have identified ways to stimulate retinal ganglion cells (RGCs), the nerve cells in the eye that convey visual signals to the brain, to begin regenerating injured axons back the brain.

Tau PTM Profiles Identify Patient Heterogeneity and Stages of Alzheimer’s Disease
Alzheimer’s disease (AD) is associated with aging and results in devastating disability and diminished quality of life; its occurrence will reach epidemic proportions by 2050 if not abated. The pathological hallmarks of AD are the two proteins β-amyloid (Aβ) and Tau. Aβ forms extracellular plaques (Glenner and Wong, 1984; Masters et al., 1985), whereas Tau forms intracellular neurofibrillary tangles (NFTs) (Grundke-Iqbal et al., 1986; Kosik et al., 1986; Wood et al., 1986). Although many studies have shown the importance of Aβ, therapeutic efforts targeting Aβ have not been successful, shifting the focus to Tau.

New strategies for restoring myelin on damaged nerve cells
Loss of myelin — the fatty substance that surrounds the axons of nerve cells — is one of the reasons nerve cells fail to recover after injury and in some diseases. Myelin acts like insulation, covering the long axon threads that enable high-speed communication between neurons. Without myelin, the neurons may not be able to coordinate well, leading to less than optimal function. In new research from the laboratory of Zhigang He, PhD, of the F.M. Kirby Neurobiology Center, scientists discovered a two-pronged approach to restore myelin on regenerated axons in a mouse model of optic nerve injury. Their findings may have implications for disease associated with myelin loss, like multiple sclerosis (MS).

To Make Mini-Organs Grow Faster, Give Them a Squeeze
The closer people are physically to one another, the higher the chance for exchange, of things like ideas, information, and even infection. Now researchers at MIT and Boston Children’s Hospital have found that, even in the microscopic environment within a single cell, physical crowding increases the chance for interactions, in a way that can significantly alter a cell’s health and development.

Scar-free healing after spinal cord injury relies on specialized cells
One of the reasons people rarely recover from spinal cord injury is the scar tissue that develops, preventing nerve cells from reconnecting. But a new study from Zhigang He, PhD, of the F.M. Kirby Neurobiology Center at Boston Children’s Hospital, demonstrated a way to minimize scar cell formation in adult mice after a spinal cord injury. The study, published in Nature, offers insights for new approaches to treating spinal cord injuries.

X-Ray Vision: a New Imaging Approach for Large-Scale Connectomics
A major quest in neuroscience is to chart all of the neurons in the brain and their synaptic connections. Such a map, called a connectome, reveals how information can flow in neuronal circuits. Obtaining connectomes is challenging because it requires imaging large volumes with high resolution. Electron microscopy (EM) is often used for high resolution imaging, but typically only records a microscopic field of view. Thanks to recent efforts to automate and speed up EM, it is now feasible to image a complete fruit fly brain, but human or even mouse brains are still way too large for comprehensive EM imaging.

Pain neurons activate immune cells, opening new treatment possibilities
For a long time, pain and inflammation were thought to be two separate biological responses. But new research by Dr. Clifford Woolf of Boston Children’s Hospital and international collaborators suggests that the same sensory neurons that produce pain also trigger inflammation. And they do so by activating cells of the immune system, a relationship never described before.

Visual Responses of Retinal Axons are Selectively Shaped by Arousal
Our perception of the outside world can vary greatly depending on the state of our brain. If we are interested in a picture, even grainy details will not escape our eyes. When we doze off in a boring lecture, we may lose track of what is shown on the whiteboard, yet we can be quickly woken up by a sudden movement in front of us. The ability to flexibly filter visual information has long been thought to largely occur at late stages of processing, at the level of sensory cortex. However, earlier stages of visual processing such as the thalamus receive a variety of projections from the cortex and from neuromodulatory systems which can carry information of the brain states.

Optimized Signal Flow through Photoreceptors Supports the High-Acuity Vision of Primates
The fovea is a neural specialization that endows humans and other primates with the sharpest vision among mammals. This performance originates in the foveal cones, which are extremely narrow and long to form a high-resolution pixel array. Puzzlingly, this form is predicted to impede electrical conduction to an extent that appears incompatible with vision. Dr. Michael Do and his lab observe the opposite: signal flow through even the longest cones (0.4-mm axons) is essentially lossless.

Antisense Oligonucleotides for the Treatment of Usher Syndrome
The lab of Dr. Geleoc, at Boston Children’s Hospital, investigates the function of several hair cell genes associated with hearing loss including Usher syndrome and develops and assesses novel therapies to protect or restore auditory function. In collaboration with Dr. Lentz from Louisiana State University, she assessed the local use of short antisense oligonucleotides (ASO-29) which can alter translation and correct for mutations such as the Acadian USH1C splicing mutation (Lentz et al. Hum. Genet. 2005). The team assessed three different local applications of the ASO agent and demonstrated that intracochlear injection led to unprecedented recovery of auditory and vestibular function.

Base Editing Gene Therapy Restores Hearing in Mice
Current treatments for hearing loss focus on amplifying sound, rather than targeting the cause of the disease. Now, a team of researchers report the use of base editors to treat Baringo mice—a mouse model of recessive genetic deafness caused by a point mutation in the transmembrane channel-like 1 gene Tmc1.

Regenerative medicine could pave the way to treating baldness
When hair follicles were first generated from stem cells that had been isolated from adult mouse skin, Jay Leno — a former host of US talk show The Tonight Show — joked that scientists “cured baldness … at least in mice”. Sixteen years on, the current host will have the opportunity to mention that scientists have ‘cured’ baldness in humans, now that Lee et al., writing in Nature, have regenerated hair follicles from human stem cells.

Internal brain timers linked with motivation and behavior
Time can be measured in many ways, but what about the sexual behavior of a fruit fly? In collaboration with the lab of Dragana Rogulja, PhD at Harvard Medical School, Crickmore shows that the mating behavior of fruit flies is not haphazard. Instead, motivation and behavior are under the control of neurons that track time.
