"I am deeply honored to step into the CEO role at ASTRO to help advance our wonderful specialty,” said Dr. Kavadi. “I do not take the challenge of leaving my current role in community cancer care to lead a national organization lightly. I recognize that I will step into the role succeeding Laura Thevenot, who has led the organization with skill and distinction for the past 22 years. I know I will be at the helm of a healthy, thriving organization, and I am committed to fostering further collaboration, scientific advancement and excellence within our specialty. I am also pleased to be able to work alongside the dedicated ASTRO staff with whom I’ve had the pleasure of working with during my time as a committee volunteer and Board member. I look forward to their continued engagement to ensure we best serve our members."

Dr. Kavadi obtained his MBA from The Wharton School, his medical degree from Harvard Medical School and his bachelor’s degree in biochemistry from Rice University. He completed his radiation oncology training at the University of Texas MD Anderson Cancer Center, where he was chief resident and served on the faculty.

Dietary sucrose determines activity of lithium on gene expression and lifespan in drosophila melanogaster

Dietary sucrose determines activity of lithium on gene expression and lifespan in drosophila melanogaster
  “[...] we found that, in female D. melanogaster, the life-prolonging effect of dietary lithium is dependent on the actual sucrose content of the medium.” BUFFALO, NY- June 19, 2024 – A new research paper was published in Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science) Volume 16, Issue 11, entitled, “Dietary sucrose determines the regulatory activity of lithium on gene expression and lifespan in Drosophila melanogaster.” The amount of dietary sugars and the administration of lithium both impact the lifespan of the fruit fly Drosophila melanogaster. It is noteworthy that lithium ...

Assessment of CEA, CA-125, and CA19-9 as adjuncts in non-small cell lung cancer management

Assessment of CEA, CA-125, and CA19-9 as adjuncts in non-small cell lung cancer management
“[...] these inexpensive, widely available tests with rapid turnaround times and relatively short half-lives (CEA, CA-125, and CA19-9) are perfectly situated to serve as adjunctive clinical tools in the management of NSCLC.” BUFFALO, NY- June 20, 2024 – A new research paper was published in Oncotarget's Volume 15 on June 13, 2024, entitled, “Assessment of serum tumor markers CEA, CA-125, and CA19-9 as adjuncts in non-small cell lung cancer management.” Conventional tumor markers may serve as adjuncts in non-small cell lung cancer ...

Iron meteorites hint that our infant solar system was more doughnut than dartboard

Key takeaways Iron meteorites are remnants of the metallic cores of the earliest asteroids in our solar system. Iron meteorites contain refractory metals, such as iridium and platinum, that formed near the sun but were transported to the outer solar system.  New research shows that for this to have happened, the protoplanetary disk of our solar system had to have been doughnut-shaped because the refractory metals could not have crossed the large gaps in a target-shaped disk of concentric rings. The paper suggests that the refractory metals moved outward ...

Anti-trust regulators should consider their options carefully when start-ups are acquired, new study suggests

June 20, 2024 Anti-Trust Regulators Should Consider Their Options Carefully When Start-Ups are Acquired, New Study Suggests Less Blunt Options than Banning Acquisitions May Help Preserve Innovation and Competition Toronto - Promoting a competitive marketplace has been the main focus for regulators concerned with “killer acquisitions” -- when big companies swallow small startups to eliminate a potential rival. But researchers and other observers point out that blocking these purchases puts something else important at risk – innovation. Startups are sometimes driven to come up with a new process or product precisely because ...

Family conditions may have more of an impact on upward social mobility than gender inequality

Family conditions—specifically, how similar one’s social status and background is to one’s parents’ status—may play a bigger role in determining how easily an individual can shift into a wealthier socioeconomic class than gender inequality, according to a study of 153 countries published June 20, 2024 in the open-access journal PLOS ONE by Khanh Duong from Maynooth University, Ireland. As global inequality increases, researchers have found that countries with higher levels of income inequality tend to experience lower rates of class mobility (in other words, individuals in a lower socioeconomic ...

In two separate clinical studies, combined immunotherapy approach enhances cancer patient response

Because not all cancer patients respond to a leading type of cancer immunotherapy drug, known as an immune checkpoint inhibitor, scientists explored whether adding janus kinase (JAK) inhibitors – drugs that treat chronic inflammation – could help. In two separate clinical studies, researchers found that adding JAK inhibitors did improve patients’ responses to cancer checkpoint inhibitor immunotherapies. “Aside from the exciting findings of the early phase trials reported by [both groups], they provide a great deal of data with complex analyses of immune ...

Airborne mapping reveals roles for biogenic sources and temperature in air pollution emissions in Los Angeles

Airborne observations over California have revealed that biogenic sources of volatile organic compounds (VOCs) – blooming trees and growing plants – dominate summertime air pollutant formation in Los Angeles, in a way that increases with temperature. Future air pollution regulations thus need to consider that only 40% of urban VOC emissions (those not tied to biogenic sources) can be mitigated through regulations, say the authors. Ambient air pollution – the fourth-leading global ...

Old bombs reveal new insights: Plants store more carbon, but for a shorter time frame, than we thought

Analysis of radiocarbon produced during nuclear bomb testing in the 1960s suggests that current Earth system models underestimate carbon uptake into terrestrial vegetation and soils. But, say the study’s authors, this storage is more short-lived than previously thought. The findings suggest that anthropogenic carbon dioxide will not reside as long in the terrestrial biosphere as models currently predict. Accurate climate predictions, crucial for developing effective climate policies, require a robust representation of the global carbon cycle. It’s thought that vegetation and soils account for taking up approximately 30% of anthropogenic carbon dioxide (CO2) ...

The time it takes a person to decide can predict their preference

The time it takes a person to decide can predict their preference
Researchers led by Sophie Bavard at the University of Hamburg, Germany, found that people can infer hidden social preferences by observing how fast others make social decisions. Publishing June 20th in the open-access journal PLOS Biology, the study shows that when someone knows the options being considered by another person, and they know how long it takes them to reach their decisions, they can use this information to predict the other person’s preference, even if they do not know what the actual choices were. How do we know what someone’s social preferences ...
