Marquis Who's Who Recognizes Steven M. Stanley for Expertise in Paleontology

UNIONDALE, NY / ACCESS Newswire / February 4, 2025 / Marquis Who's Who honors Steven M. Stanley, PhD, for his expertise in paleontology. Dr. Stanley is a leading authority in paleontology and an acclaimed author, focusing his career on evolutionary biology and education. Now a research professor at Florida State University, Dr. Stanley's contributions to science are widely recognized and his latest work, 'T. Rex, Darwin and Adventures Out West,' further exemplifies his ability to inspire both within and beyond the scientific community.
'Writing this novel was a way to engage with a broader audience and share the excitement of discovery that has driven my career in paleontology,' Dr. Stanley explains. His previous works, such as 'Children of the Ice Age' and 'The New Evolutionary Timetable,' have been lauded for their depth and accessibility, with 'The New Evolutionary Timetable' earning a nomination for an American Book Award.
Dr. Stanley's passion for science began early in life. Growing up on 24 acres of river land, he developed an interest in collecting rocks and minerals, which later led him to study geology at Princeton University, where he graduated summa cum laude. He went on to earn a PhD from Yale University in 1968. His doctoral dissertation, 'Relation of Shell Form to Life Habits in the Bivalvia (Mollusca),' remains a seminal work in the study of skeletal morphology and continues to be cited nearly 50 years after its publication.
At age eight, 'The First Book of Stones' motivated Dr. Stanley to collect rocks and minerals. At 15, a famous medical researcher invited him for a month of mineral collecting in Colorado. The next summer, he collected minerals in northern Michigan. Dr. Stanley became the youngest full professor at Johns Hopkins University at 32 years old, where he founded and chaired a part-time evening master's program in environmental sciences and policy. Since 1972, he has been a research associate at the Smithsonian Institution, where he maintains a laboratory for ongoing research.
In 'T. Rex, Darwin and Adventures Out West,' Dr. Stanley weaves a narrative rich in scientific detail and human drama. The story, which at one point becomes a mystery, follows a group of college students and their professors on a journey that challenges their understanding of the world around them. 'The novel allowed me to explore themes of adventure, discovery and the bonds that form through shared experiences,' he adds.
Dr. Stanley is renowned for his contributions to evolutionary biology, particularly his work on the theory of punctuated equilibria and the magnesium/calcium ratio in seawater. These studies have significantly advanced the understanding of marine life's history and evolutionary processes.
Dr. Stanley's textbook 'Principles of Paleontology,' co-authored with David Raup, transformed paleontology education in the U.S. and abroad. His historical geology text 'Earth System History,' now in its seventh edition, has been used by approximately half a million students.
Dr. Stanley's work has earned him numerous accolades, including the Penrose Medal, which is the highest award of the Geological Society of America, for eminence in pure research, and the Mary Clark Thompson Medal from the National Academy of Sciences. His influential book, 'Macroevolution: Pattern and Process,' remains widely cited in both biology and paleontology. Dr. Stanley attributes his success to deductive reasoning, creativity and a willingness to embrace controversy.
In 'T. Rex, Darwin and Adventures Out West,' Dr. Stanley's unique perspective as a scientist and storyteller shines through, making it a must-read for anyone interested in the intersection of science and literature. Looking ahead, Dr. Stanley plans to write another textbook.

Adolore BioTherapeutics Announces Publication Demonstrating Biosafety and Efficacy of Kv7 Activating rdHSV-CA8* Analgesic Gene Therapy for Chronic Pain via the Intra-Articular Route in Mice

Findings highlight the advantages of Adolore's approach for the delivery of proprietary gene therapy directly to specialized pain-sensing peripheral nerves (nociceptors) that mediates profound analgesia with the potential to address the great unmet need for non-opioid chronic pain therapies Data further supports the clinical-translational value of Adolore's proprietary non-opioid analgesics for treating chronic non-cancer pain These data support the Company's continuing efforts to progress with IND-enabling studies of ADB-102 gene therapy for the treatment of osteoarthritis (OA) chronic knee pain. DELRAY BEACH, FL / ACCESS Newswire / June 15, 2025 / Adolore BioTherapeutics ("Adolore" or the "Company"), a biotechnology company focused on developing breakthrough opioid-free gene therapy treatments for chronic pain and neurological disorders, today announced the publication of its manuscript titled, "Biosafety and Efficacy of Kv7 Activating rdHSV-CA8* Analgesic Gene Therapy for Chronic Pain Via the Intra-Articular Route in Mice1," in the peer-reviewed journal, Molecular Therapy. Roy Clifford Levitt, MD, Clinical Professor at the University of Miami, Principal Investigator and Program Director of the NIH, NINDS, HEAL Award supporting ADB-102 development for the treatment of chronic knee pain due to OA, and Founder & Executive Chairman of Adolore BioTherapeutics, published biosafety and efficacy data from preclinical studies of Adolore's gene therapy expressing a human carbonic anhydrase-8 variant peptide (CA8*). In model systems, replication-defective, disease-free, herpes simplex virus (rdHSV) gene therapy expressing an analgesic carbonic anhydrase-8 (CA8*) peptide variant corrects somatosensory hyperexcitability by activating Kv7 voltage-gated potassium channels, produces profound, long-lasting analgesia and treats chronic pain from knee OA. In these studies, we provide the first non-Good Laboratory Practices (GLP) biosafety, efficacy, biodistribution, shedding, and histopathology examination of this rdHSV-CA8* via the intra-articular knee route of administration. Naive mice were examined for clinical safety, distribution of virus across all major tissues, knee histopathology, and analgesic efficacy. We observed no signs of persistent toxicity or histopathology, viral genomes remained where they were injected, and there was no evidence of shedding. Profound analgesia persisted for >6 months without functional impairments. These initial biosafety and efficacy data support further development of rdHSV-CA8* for treating chronic knee pain due to moderate-to-severe OA. Dr. Levitt, commented, "Kv7 voltage-gated potassium channel activators, like rdHSV-CA8* open these channels and hyperpolarize nociceptors making them less excitable to produce profound analgesia. Kv7 activators are well-known to produce potent non-opioid-based analgesia in many human chronic pain conditions. While Kv7 openers are no longer available due to off-target adverse events related to systemic administration, they have been successfully translated from animal models to human chronic pain conditions. Bolstered by our substantial body of published data, we continue to develop our innovative approach to address the significant serious unmet need for safe and effective locally acting pain therapies to replace opioids. Our preclinical data strongly support continued preclinical development toward an IND and clinical studies of ADB-102." The Company's lead development program for the treatment of chronic pain in knee osteoarthritis is fully funded by a UG3/UH3 grant awarded to the University of Miami by NIH/NINDS HEAL program to support all formal pre-clinical GLP/GMP/GCP development work through a first-in-human study of ADLR-1l01 in patients expected to commence in 2026. 1 Levitt et al., Biosafety and efficacy of Kv7 activating rdHSV-CA8* analgesic gene therapy for chronic pain via the intraarticular route in mice, Molecular Therapy (2025), About Carbonic Anhydrase-8 (CA8*) Gene Therapy CA8* (variants of naturally occurring human carbonic anhydrase-8 analgesic peptides) gene therapies are a novel class of neuronal calcium channel inhibitors that activate Kv7 voltage-gated potassium channels and are administered locally and long-acting. Oral small molecule pain therapeutics that activate Kv7 voltage-gated potassium channels demonstrated proven analgesic efficacy before they were removed from the market due to severe adverse events related to systemic exposure and their metabolism. CA8* gene therapy provides versatile dosing regimens and routes of administration, including intra-articular, intra-neuronal (nerve block), and intradermal injection. This non-opioid CA8* mechanism-of-action addresses neuropathic, inflammatory, and nociceptive pain, which applies to a broad range of chronic pain indications and neurological disorders. These conditions include osteoarthritis, lower back, and cancer pain; diabetes and other forms of peripheral neuropathy; as well as rare pain conditions such as erythromelalgia, a heritable chronic pain condition and epilepsy and hearing loss. About Adolore BioTherapeutics, Inc. Adolore BioTherapeutics, Inc., is a biotechnology company focused on developing novel therapies for treating chronic pain using a revolutionary intra-cellular replication-defective HSV (rdHSV) drug delivery platform that is disease-free, non-toxic, and permits localized peripheral nervous system delivery of proprietary biotherapeutics. This rdHSV gene therapy technology incorporates an established re-dosing strategy and an excellent safety profile. HSV vectors are known for their stability and prolonged gene expression, providing an excellent basis for the long- term treatment of chronic pain conditions and neurological disorders. Our best-in-class CA8* programs are long-acting, locally administered gene therapies that are opioid-free Disease-Modifying Anti-Pain therapies (DMAPs) designed to treat many forms of chronic pain, epilepsy and hearing loss. Leveraging its innovative gene therapy vectors expressing CA8* analgesic peptides (ADLR-1001), Adolore is currently advancing two preclinical development programs: ADB-101 for the treatment of patients' chronic pain caused by erythromelalgia, an orphan disease, and ADB-102, their lead program for the treatment of patients with chronic pain caused by knee OA. Based on substantial compelling preclinical data generated to date, the Company is progressing these programs toward IND filings and first-in-human clinical studies. Adolore has two additional programs: ADB-104 for Drug-Resistant Refractory Focal Epilepsy and ADB-105 for Acute Severe Hearing Loss.

Scientists discover ‘dragon prince' dinosaur, the T. Rex's missing ancestor

Tyrannosaurus rex is a carnivorous icon. Exceeding 40 feet in length and nine tons, the bone-crushing giant stands out as the largest and last of its meat-eating family. Now a new and far smaller tyrannosaur is filling in the famous dinosaur's evolutionary backstory. The newest addition to the tyrannosaur family tree is named Khankhuuluu mongoliensis, which translates to 'dragon prince from Mongolia.' Described this week in the journal Nature, the dinosaur has been identified for the first time from two partial skeletons that include skull bones, vertebrae, part of the hips, and limb bones. Altogether, the pieces reveal a slender tyrannosaur that roamed Cretaceous Mongolia about 86 million years ago and was about 13 feet long—or about the size of juvenile T. rex that would stalk North America 20 million years later. In fact, Khankhuuluu even looked like a juvenile of later, larger tyrannosaurs, with round eye sockets, blade-like teeth, and long, shallow jaws better suited to biting fast rather than hard. (​T. rex had lips, upending its enduring pop culture image.) Khankhuuluu does more than simply add another dinosaur to the ever-growing roster of dinosaurs. 'Khankhuuluu gives us the origin story of tyrannosaurs,' says University of Calgary paleontologist and study co-author Darla Zelenitsky. In the early 1970s, Mongolian paleontologist Altangerel Perle found a pair of partial tyrannosaur skeletons in the eastern part of the country. The bones seemed similar to a small tyrannosaur that had been named before, Alectrosaurus. But when University of Calgary paleontologist and study co-author Jared Voris studied the bones during a research trip to Mongolia in 2023, he soon realized that the bones did not belong to Alectrosaurus at all. The bones from the two skeletons belonged to a new form of tyrannosaur that had been waiting to be discovered in collections for half a century. 'It had features like a hollow air chamber in side its nasal bone, which no other tyrannosaur species has,' Voris says. The fossils deserved a new name and have been recategorized as Khankhuuluu. Voris has found tyrannosaurs hiding in plain sight before. In 2020, Voris and colleagues named the 80 million-year-old tyrannosaur Thanatotheristes from bones assigned to another species found in Alberta. ("Reaper of Death" tyrannosaur discovered in Canada.) The finds are part of a burgeoning array of tyrannosaur discoveries. Instead of a simple line of evolution from early tyrannosaurs to T. rex, paleontologists have uncovered a wildly branching evolutionary bush of different tyrannosaur subgroups that came and went through the Cretaceous. The glut of new tyrannosaur species is allowing experts to piece together how big tyrannosaurs, including the gigantic T. rex, evolved and spread across vast stretches of the planet. When compared to other tyrannosaurs, the researchers found that Khankhuuluu is a close relative of the broader group of tyrannosaurs that include Gorgosaurus from Alberta, the bumpy-snouted Alioramus from Mongolia, and the iconic T. rex. The new family tree, as well as where the fossils were uncovered, create an updated picture of how tyrannosaurs evolved over 20 million years.'It is a pivotal species in understanding the evolutionary success of T. rex and its relatives,' says University College London paleontologist Cassius Morrison, who was not involved in the new study. In particular, the new analysis reveals how tyrannosaurs evolved into many different species as the carnivores wandered into new around the time of Khankhuuluu, Voris and colleagues propose, such small, slender tyrannosaurs were dispersing from prehistoric Asia into North America over a land bridge. 'Tyrannosaurs evolved into those giant apex predators and diversified very rapidly across North America,' Voris says, the first of what Zelenitsky calls 'two explosions of tyrannosaurs.' Some of the predators remained slender and chased smaller prey while others became bulkier and hunted larger dinosaurs, and they roamed habitats from southern California to New Jersey. (See how these fierce dinos evolved in our pages over 100 years.) The new study suggests, however, that the direct ancestors of T. rex, did not evolve in North America. Voris and colleagues propose that around 79 and 78 million years ago at least one lineage of tyrannosaurs ventured back into Asia. The researchers know this because of the close relationship of two tyrannosaur groups that at a glance might seem very different. When tyrannosaurs returned to Asia during this period and underwent their second explosion, one group was relatively slender and had long snouts decorated with small horns, like the 'Pinocchio' dinosaur Qianzhousaurus. The other group began to grow larger, with deep skulls adept at crushing bones, like Tarbosaurus. T. rex evolved from ancestors in the second group, a lineage of bone-crushers that once again crossed the land bridge back into North America between 73 and 67 million years ago—making T. rex a new form of predator that arrived from another continent. 'The new analysis provides strong support that the ancestors of T. rex evolved from a group of tyrannosaurs that ventured back to Asia after they had undergone an evolutionary radiation in North America,' Morrison says. Ultimately, the study suggests that the rise of one of Earth's largest carnivores was due to a back-and-forth between North America and Asia that took place over a period of 20 million years. Had a devastating asteroid impact not abruptly ended the Cretaceous 66 million years ago, tyrannosaurs would have undoubtedly kept changing.

Scientists discover ‘dragon prince' dinosaur, the T. Rex's missing ancestor

Khankhuuluu mongoliensis was slender with features like no other member of the tyrannosaur family tree. This illustration depicts how the slender Khankhuuluu mongoliensis may have appeared as it roamed Mongolia during the Cretaceous period. The newest addition to the tyrannosaur family, the discovery of this "dragon prince from Mongolia" sheds light on the origins of Tyrannosaurus rex. Illustration by Julius Csotonyi Tyrannosaurus rex is a carnivorous icon. Exceeding 40 feet in length and nine tons, the bone-crushing giant stands out as the largest and last of its meat-eating family. Now a new and far smaller tyrannosaur is filling in the famous dinosaur's evolutionary backstory.

'Khankhuuluu gives us the origin story of tyrannosaurs,' says University of Calgary paleontologist and study co-author Darla Zelenitsky. Comparing the fossils of mature Khankhuuluu (a, d, g) with fossils of mature Gorgosaurus (c, f, i) and juvenile Gorgosaurus (b, e, h) provides new insights into the evolutionary lineage between the smaller-bodied tyrannosauroids, such as Khankhuuluu, and the larger eutyrannosaurians like Gorgosaurus and Tyrannosaurus. Silhouettes compare the sizes of Khankhuuluu (left) with a juvenile (right) and adult (middle) Gorgosaurus. Scale bars, 5 cm (individual elements) and 1 m (silhouette). Illustration by Voris et al.
