America is experiencing a crisis of expertise—one that has worsened since the COVID-19 pandemic and shows little sign of abating. A nationally representative survey conducted by the Survey Center on American Life finds that a growing number of Americans are distrustful of scientific and medical experts. This phenomenon cuts across demographic lines but is most acute among Republicans and evangelical Christians. It has implications for a wide range of scientific and medical fields—including climate change, public health, and artificial intelligence (AI)—posing significant challenges to public decision-making and democratic debate.
In a study on the prevalence of attention-deficit/hyperactivity disorder (ADHD) and its association with crash risk among older adult drivers, researchers at Columbia University Mailman School of Public Health found that older adult drivers with ADHD are at a significantly elevated crash risk compared with their counterparts without ADHD. Outcomes included hard- braking events, and self-reported traffic ticket events, and vehicular crashes.
Until now research on ADHD and driving safety was largely limited to children and young adults, and few studies assessed the association of ADHD with crash risk among older adults. The results are published online in JAMA Network Open.
The novel class of optical modulators can make data transfer over optical fiber communication faster and more efficient.
Whether you’re battling foes in a virtual arena or collaborating with colleagues across the globe, lag-induced disruptions can be a major hindrance to seamless communication and immersive experiences.
That’s why researchers with UCF’s College of Optics and Photonics (CREOL) and the University of California, Los Angeles, have developed new technology to make data transfer over optical fiber communication faster and more efficient.
The World Health Organization has recommended a shot called R21 to prevent the disease in children.
The World Health Organization (WHO) has endorsed a second malaria vaccine to protect children against the deadly disease, which killed 619,000 people in 2021.
Researchers say that the vaccine, known as R21, is easier to make than the first-approved malaria vaccine, called RTS,S, and will be cheaper per dose.
Large study found three genes strongly linked to vegetarianism.
From Impossible Burger to “Meatless Mondays,” going meat-free is certainly in vogue. But a person’s genetic makeup plays a role in determining whether they can stick to a strict vegetarian diet, a new Northwestern Medicine study has found.
The findings open the door to further studies that could have important implications regarding dietary recommendations and the production of meat substitutes.
The development of attosecond pulses of light allowed researchers to explore the frame-by-frame movement of electrons.
To catch a glimpse of the subatomic world’s unimaginably fleet-footed particles, you need to produce unimaginably brief flashes of light. Anne L’Huillier, Pierre Agostini and Ferenc Krausz have shared the 2023 Nobel Prize in Physics for their pioneering work in developing the ability to illuminate reality on almost inconceivably brief timescales.
Rishi Sunak is considering introducing some of the world’s toughest anti-smoking measures that would in effect ban the next generation from ever being able to buy cigarettes, the Guardian has learned.
Whitehall sources said the prime minister was looking at measures similar to those brought in by New Zealand last December. They involved steadily increasing the legal smoking age so tobacco would end up never being sold to anyone born on or after 1 January 2009.
Researchers publicly call out theory that they say is not well supported by science, but that gets undue attention.
A letter, signed by 124 scholars and posted online last week1, has caused an uproar in the consciousness research community. It claims that a prominent theory describing what makes someone or something conscious — called the integrated information theory (IIT) — should be labelled “pseudoscience”. Since its publication on 15 September in the preprint repository PsyArXiv, the letter has some researchers arguing over the label and others worried it will increase polarization in a field that has grappled with issues of credibility in the past.
