New analysis: Kaepernick was denied his “right to work” because he, like other Black male athletes before him, challenged structural racism and white supremacy
2023-06-23
A nascent literature is emerging that analyzes the case of Colin Kaepernick who was “locked out” of the National Football League (NFL) beginning in 2017 because he chose to protest police brutality, systemic racism, and white supremacy. Using status expectations states theory and prototypicality theory, this research re-conceptualizes Kaepernick’s lock-out as an infringement on his right to work. First, researchers utilize a modified case-study approach comparing his experiences to those of six other Black male athletes who were “locked out.” Second, researchers utilize data and “matched cases” to demonstrate empirically ...
All the immunity, none of the symptoms
2023-06-23
LA JOLLA (June 23, 2023)—Worldwide, more than a million deaths occur each year due to diarrheal diseases that lead to dehydration and malnutrition. Yet, no vaccine exists to fight or prevent these diseases, which are caused by bacteria like certain strains of E. coli. Instead, people with bacterial infections must rely on the body taking one of two defense strategies: kill the intruders or impair the intruders but keep them around. If the body chooses to impair the bacteria, then the disease can occur without the diarrhea, but the infection can still be transmitted—a process called asymptomatic carriage.
Now, Salk scientists have found that ...

Drug decelerates bacterial race to antibiotic resistance
2023-06-23
A team of researchers at Baylor College of Medicine is gaining ground in their search for solutions to the global problem of bacterial antibiotic resistance, which was responsible for nearly 1.3 million deaths in 2019.
The team reports in the journal Science Advances a drug that, in laboratory cultures and animal models, significantly reduces the ability of bacteria to develop antibiotic resistance, which might prolong antibiotic effectiveness. The drug, called dequalinium chloride (DEQ), is a proof-of-concept for evolution-slowing drugs.
“Most people with bacterial infections ...

The force of blows to the head, not just how many, raises likelihood of CTE
2023-06-23
For years, researchers studying chronic traumatic encephalopathy, or CTE, believed the primary cause of it was repetitive hits to the head, whether or not those hits caused concussions. They believed the more frequently that a person sustained head blows, the more likely they were to develop neurological and cognitive struggles later in life.
A new collaborative study conducted by researchers at Boston University, Mass General Brigham, and Harvard Medical School—using brains donated to BU’s ...

Researchers show how a tumor cell’s location and environment affect its identity
2023-06-23
Using 3-D models of ovarian cancer tumors, scientists found differences in gene activity based on where a cell is in a tumor, demonstrating how a cell’s location and environment in a cancerous tumor can strongly influence which genes are active and the cell’s role in the cancer’s biology. More specifically, the team co-led by researchers at the National Center for Advancing Translational Sciences (NCATS), part of the National Institutes of Health, showed that gene activity in cells at or near a tumor’s surface differed from that of cells closer to the tumor center.
The approach pairs the use of a technology to reveal the genetic activity of single ...

How popular steroids could mess up some cancer treatments
2023-06-23
Immunotherapy is among the newest and most potent weapons against cancer. It prompts the immune system to recognize tumors as intruders in the body and attack. But not all patients respond well to immunotherapy. Why? Scientists aren’t always sure.
Sometimes, immunotherapy patients experience side effects that steroids called glucocorticoids (GCs) can treat. GCs are often used to regulate the immune response in conditions such as asthma, Crohn’s disease, and even COVID-19. Yet just how they work is also a mystery.
Now, Cold Spring Harbor Laboratory (CSHL) researchers may be closer to answering both questions. Their new research indicates GCs may indirectly lead ...
Treatment for opioid use disorder varies widely among states, study finds
2023-06-23
Despite a national opioid overdose epidemic supercharged by a surge of illicit fentanyl, new research from Oregon Health & Science University reveals wide discrepancies among U.S. states in effectively treating opioid use disorder among people covered by Medicaid.
The study, published today in the journal JAMA Health Forum, found that in many states, fewer than half of people diagnosed with opioid use disorder received proven medications to treat it.
“We fail people by not providing adequate treatment to people with opioid use disorder enrolled in Medicaid,” said lead author Stephan Lindner, Ph.D., associate professor in ...
Patterns, characteristics of nicotine dependence among adults with cigarette use
2023-06-23
About The Study: There were significant reductions in nicotine dependence prevalence from 2006 to 2019 among U.S. adults with cigarette use and all examined subgroups 26 years and older. Adults 50 years and older (especially those with major depressive episode and/or substance use disorder) had the highest nicotine dependence prevalence compared with other age groups, highlighting the importance of assisting with smoking cessation efforts and addressing nicotine dependence for this older population. Evidence-based tobacco cessation strategies tailored to age and comorbidities are ...
Characteristics of medical evacuation by train in Ukraine
2023-06-23
About The Study: The findings of this study suggest that medical evacuation in a war zone by converted trains is possible and can improve access to health care for war-affected patients. The presence of intensive care capacity on board allows for transport of more severely ill or injured individuals. However, the target population should not be limited to trauma patients, as health care institutions affected host a much broader population whose needs and urgency for evacuation may change over time.

Global warming accelerates CO2 emissions from soil microbes
2023-06-23
The rise in atmospheric carbon dioxide (CO2) concentration is a primary catalyst for global warming, and an estimated one fifth of the atmospheric CO2 originates from soil sources. This is partially attributed to the activity of microorganisms, including bacteria, fungi, and other microorganisms that decompose organic matter in the soil utilizing oxygen, such as deceased plant materials. During this process, CO2 is released into the atmosphere. Scientists refer to it as heterotrophic soil respiration.
Based on a recent study published in the scientific journal Nature Communications, a team of researchers from ...
