Every mosquito has a type — and you may not be it

Study debunks the “mosquito magnet” myth — and lays groundwork for next generation of repellents to fight dengue, Zika and West Nile 

MIAMI, Aug. 7, 2026 /PRNewswire/ — There is no such thing as a universal mosquito magnet.

In a new study published in iScience, Florida International University (FIU) researchers pitted 119 human volunteers against three of the world’s most dangerous mosquito species and found that not one person was attractive to all three. Every species had its own type. Attraction was largely driven by chemistry — an individual’s body chemistry.

This single finding could reshape how the world fights mosquito-borne disease. Because each species decodes human scent differently, the results could help scientists develop next-generation, species-specific repellents.

“Isolating the components of human odor that attract or repel mosquitoes could lead to novel strategies to combat vector-borne diseases,” said Matthew DeGennaro, a neurogeneticist who leads the research team and directs the Biomolecular Sciences Institute at FIU, Miami’s state university. 

The three species studied — Aedes aegypti, Aedes albopictus (Asian tiger mosquito) and Culex quinquefasciatus (southern house mosquito) — together spread yellow fever, dengue, Zika, West Nile and other diseases. The study, led by Ph.D. student Kaylee Marrero, is the first to directly compare how multiple mosquito species respond to the same people. 

“We didn’t expect the species to prefer different people when we started the study,” Marrero said. “Each species having a distinct microbial signature that they use as a cue was so surprising to me.” 

Each species had a distinct set of turn-ons and turn-offs: 

Aedes aegypti preferred people wearing no added scent whose skin lacked certain volatile compounds. These daytime feeders showed a slight preference for men over women. Aedes albopictus (Asian tiger) was drawn to elevated ketones and plant-like volatile compounds naturally secreted by skin. Like Aedes aegypti, it feeds during the day. Culex quinquefasciatus (southern house) fed after dark and keyed in on the skin microbiome — the microscopic ecosystem of bacteria, fungi and microbes naturally living on people’s skin. Some bacterial families were a green light to feed; others drove the mosquitoes away. 

Human scent is a complex space of more than 1,000 volatile organic compounds, many still uncharacterized. Rather than agreeing on who was most attractive, each species consistently favored a different subset of people — evidence that the species have evolved distinct ways of sensing humans. Alongside the preference tests, the team collected odor and microbiome samples to identify which compounds and bacteria were present, and at what levels. 

“This connected so well with the differences in skin bacteria and odors,” DeGennaro said. “It is clear to me now that our skin microbiomes define our human odor signature. Each species found its own way to decode that signature.” 

By mapping these species-specific chemical cues, the FIU team is laying the groundwork for repellents and public health strategies tailored to the mosquito that matters most in a given region.

University of Phoenix research chair presents pilot findings on AI-assisted empathy at 2026 American Psychological Association convention

Published

Dr. Rodney Luster shares early findings and ethical considerations for using generative AI as an adjunct to psychotherapy and counselor training.

PHOENIX, Aug. 7, 2026 /PRNewswire/ — Rodney Luster, PhD, University research chair and chair of the Center for Leadership and Entrepreneurial Research (CLER) in the University of Phoenix College of Doctoral Studies, presented pilot research examining the potential use of generative artificial intelligence to support structured empathy practice at the 2026 American Psychological Association annual convention.

Luster’s virtual poster, “In-Session AI Reflection and Empathy: Pilot Findings and Practice Implications,” will be presented August 8 as part of the Society for the Advancement of Psychotherapy, Division 29 virtual poster session. The study explored whether professionally facilitated engagement with researcher-constructed AI personas could provide a repeatable environment for practicing perspective-taking, emotional labeling, validation and repair-oriented communication.

Key points from the pilot study include:

Ten adults completed two facilitated AI-persona encounters and pre- and post-experience empathy assessments.Mean empathy assessment scores increased from 23.10 to 25.80, with nine of 10 participants recording higher post-experience scores.The research emphasizes that generative AI should be considered an adjunctive process tool, not a standalone intervention or substitute for instructors, supervisors, clinicians or human relationships.The exploratory findings demonstrate feasibility and a promising association, not evidence that AI independently caused lasting changes in empathy.

“Empathy is central to effective counseling, yet it can be difficult to practice and assess consistently,” Luster said. “This small pilot explored whether professionally facilitated AI personas could offer a repeatable, transcript-rich environment for structured rehearsal and reflection. The goal is not to replace instructors, supervisors or human relationships, but to examine how AI might responsibly support the work they already do.”

Pilot study explores structured empathy practice

Generative AI is increasingly used by individuals to reflect on interpersonal conflict and emotional distress, but clinicians and counselor educators have limited research-based guidance on whether AI-facilitated reflection can support processes associated with therapeutic change.

The pilot study examined structured interactions with AI personas created by the researchers to present participants with complex relational experiences. Participants were guided to consider multiple viewpoints, identify and label emotions, respond with curiosity and validation, and develop language oriented toward relational repair.

Participants completed an eight-item empathy self-assessment before and after the experience. Researchers also reviewed the interaction transcripts for indicators such as perspective taking, empathic concern, emotional labeling, continuity tracking, curiosity and meaning-making.

The transcripts allowed researchers to examine not only participants’ final responses, but also how their communication developed throughout each interaction. According to the pilot findings, progression appeared to depend on accumulated relational safety rather than a single “correct” response.

Early findings suggest potential for guided reflection

Mean empathy scores increased by 2.70 points, from 23.10 before the facilitated experiences to 25.80 afterward. The study reported a within-person effect size of dz = 0.89, and nine of the 10 participants increased their assessment scores.

Nine participants also reached the third level of the researchers’ relational progression framework, which represented disclosure of an underlying emotional wound. Qualitative findings included:

Greater emotional clarityIncreased openness to alternative perspectivesReduced certainty in hostile interpretations of another person’s actionsGreater readiness to use repair-oriented languageIncreased recognition of emotional meaning across an interaction

The results are preliminary. The small pilot did not include a control group, and the findings should not be interpreted as proof that AI caused durable changes in empathy. Participant expectations, the facilitation process and other factors may have contributed to the observed changes.

Ethical use depends on clinician oversight

Luster’s presentation placed significant emphasis on the ethical and professional guardrails required when integrating generative AI into psychotherapy or counselor preparation.

The proposed implementation framework maintains that clinicians, instructors and supervisors must retain responsibility for interpreting AI-generated material and determining how, or whether, it should be incorporated into an individual’s treatment or learning experience.

Considerations outlined in the presentation include:

Providing clear informed-consent languageProtecting client privacy and confidentialityEstablishing appropriate therapeutic and instructional boundariesDocumenting the use of AI-assisted exercisesPreserving client autonomyReviewing AI-generated output rather than accepting it uncriticallyRecognizing circumstances in which AI-assisted activities may be inappropriate

The presentation identified potential contraindications involving high-acuity situations, paranoia or impaired reality testing, heightened suggestibility and increased privacy vulnerability. These guardrails reinforce the study’s central position that generative AI should strengthen rather than replace human relationships and professional judgment.

Implications for research and practice

The pilot suggests that professionally facilitated AI personas may offer a structured setting for rehearsing difficult conversations, receiving immediate relational feedback and reviewing detailed transcripts with an instructor, supervisor or clinician.

Potential applications identified in the presentation include guided reflection involving relationship rupture, workplace conflict, values-based decision-making and supervised counselor empathy practice. The approach may allow participants to practice communication responses repeatedly before applying them in interpersonal or professional settings.

Further research is needed to determine whether the findings can be replicated and whether observed changes continue over time. Recommended next steps include studies with larger and more demographically diverse samples, controlled comparisons, independent validation of the researchers’ relational progression framework and assessment of outcomes across different participant and clinical populations.

Happiest Baby Announces Voluntary Recall for Extra-Small and Extra-Large SNOO Sack Accessories

Published

on

By

LOS ANGELES, Aug. 7, 2026 /PRNewswire/ — Today, Happiest Baby announced a voluntary recall of its extra-small (XS) and extra-large (XL) SNOO Sacks®. This action follows a communication from the U.S. Food and Drug Administration (FDA), advising Happiest Baby that the Company needed to obtain FDA’s premarket authorization for those two sizes.

Out of an abundance of caution, customers are asked to discontinue use and discard their XS and XL SNOO Sacks.

This recall does not include the SNOO Smart Sleeper or the small, medium, and large SNOO Sacks. SNOO Smart Sleeper® and the small, medium, and large SNOO Sacks received FDA

De Novo authorization in 2023. In addition, it does not affect any Sleepea® swaddle sacks, including XS and XL Sleepeas. (Sleepea sacks have no wings and are only designed for use outside of a SNOO.)

The XS and XL SNOO Sacks were launched after the original FDA De Novo submission and, as a result, were not part of the FDA review.

Note: The XS SNOO Sack is ¾” narrower and 2″ shorter than the FDA-authorized small size sack. The XL SNOO Sack is ½” wider and 3″ longer than the FDA-authorized large size sack. The FDA stated that these changes could result in a fit that was too loose or too tight. Happiest Baby has not received any reports of injury in connection with the use of XS or XL SNOO Sacks.

Anyone who purchased an XS or XL SNOO Sack, in the U.S. from Happiest Baby’s website can apply for a refund or exchange for a small, medium, or large SNOO Sack by visiting http://happiestbaby.com/xs-xl-support. Customers who purchased an XL SNOO Sack from Amazon should contact Amazon directly (888-280-4331).

Happiest Baby remains committed to meeting the highest standards for quality, safety, and family wellbeing. SNOO remains the first and only baby bed granted FDA De Novo authorization for keeping babies safely positioned on the back—all naps, all night.
