Is the universe a computer simulation?

 Mathematical proof debunks the idea that the universe is a computer simulation

It's a plot device beloved by science fiction: our entire universe might be a simulation running on some advanced civilization's supercomputer. But new research from UBC Okanagan has mathematically proven this isn't just unlikely—it's impossible. Dr. Mir Faizal, Adjunct Professor with UBC Okanagan's Irving K. Barber Faculty of Science, and his international colleagues, Drs. Lawrence M. Krauss, Arshid Shabir and Francesco Marino have shown that the fundamental nature of reality operates in a way that no computer could ever simulate. Their findings, published in the...Read more...

Book: Legal Impacts to Airports from State Legalization of Cannabis

 Airports, while physically located within individual states, operate as instruments of commerce subject to federal jurisdiction as part of the national transportation system. This duality, requiring airports to navigate multiple layers of laws and regulations, is particularly significant in the context of cannabis, where some states have legalized the substance for certain uses while federal law continues to prohibit it.

Understanding "Magnetic Reconnection”

 NASA’s newest mission, TRACERS, soon will begin studying how Earth’s magnetic shield protects our planet from the effects of space weather. Short for Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites, the twin TRACERS spacecraft lifted off at 2:13 p.m. EDT on July 23 aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California. “NASA is proud to launch TRACERS to demonstrate and expand American preeminence in space science research and technology,” said acting NASA Administrator Sean Duffy. “The TRACERS satellites will move us forward in decoding space weather and further our understanding of the connection between Earth and the Sun. This mission will yield breakthroughs that will advance our pursuit of the Moon and, subsequently, Mars.” Riding along with TRACERS were the Athena EPIC (Economical Payload Integration Cost), PExT (Polylingual Experimental Terminal), and REAL (Relativistic Electron Atmospheric Loss) missions—three small satellites to demonstrate new technologies and ...

Book: Cybercrime Classification and Measurement

 Cybercrime poses serious threats and financial costs to individuals and businesses in the United States and worldwide. Reports of data breaches and ransomware attacks on governments and businesses have become common, as have incidents against individuals (e.g., identity theft, online stalking, and harassment). Concern over cybercrime has increased as the internet has become a ubiquitous part of modern life. However, comprehensive, consistent, and reliable data and metrics on cybercrime still do not exist - a consequence of a shortage of vital information resulting from the decentralized nature of relevant data collection at the national level. Cybercrime Classification and Measurement addresses the absence credible cybercrime data and metrics. This report provides a taxonomy for the Federal Bureau of Investigation for the purpose of measuring different types of cybercrime, including both cyber-enabled and cyber-dependent crimes faced by individuals and businesses, and considers the needs for its periodic revision. This report was mandated by the ... Read more...

Book: Blueprint for a National Prevention Infrastructure for Mental, Emotional, and Behavioral Disorders

 Mental, emotional, and behavioral (MEB) disorders, including mental illness and substance use disorders, affect every U.S. population group, community, and neighborhood. Existing infrastructure focuses more on responding to MEB crises, through treatment and recovery, rather than preventing them through evidence-based policy approaches and programs. Prevention services that do exist are insufficiently funded and fragmented. Blueprint for a National Prevention Infrastructure for Mental, Emotional, and Behavioral Disorders focuses on building and sustaining a comprehensive prevention infrastructure for MEB disorders as a whole. Conclusions and recommendations of this report focus on closing research gaps, supporting an MEB disorder prevention workforce, ensuring adequate data to support prevention and reporting, establishing clear governance, securing sustainable funding, and ...

The Mystery of How Many People Are on Medicaid

 If you have been following the debate about Medicaid cuts, you know it’s a giant program, America’s largest in terms of the number of people it covers. But you may be confused about how many people Medicaid actually covers. Is it 71 million Americans, the number most commonly used in The New York Times and many press reports? Or 83 million Americans, a number Medicaid experts like us and some others frequently use? There are other numbers too, and other ways of thinking about the reach of the program. On the chance that others are confused by the different Medicaid counts, let me clear this up. The 71 million number comes from CMS administrative data (meaning program data reported from the states, not self-reported survey data). It doesn’t include the closely connected CHIP program in the 71 million count. It’s also the most recent data (2025). However, this count excludes people who get Medicaid coverage for some—but not all—Medicaid-covered services, such as for family planning. During the pandemic and the unwinding of the continuous enrollment provision, these data were updated regularly and helpful to track changes during a time of ... Read more...

Structural analysis of full-length human transmembrane protein 94 argues against its classification as a P-type Mg2+ ATPase

 In 2018, transmembrane protein 94 (TMEM94) garnered significant attention due to the correlation observed between biallelic loss-of-function variants in TMEM94 and neurodevelopmental delay, congenital heart defects, as well as distinctive facial dysmorphism1. This newly described disorder was named intellectual developmental disorder with cardiac defects and dysmorphic facies (IDDCDF)2. Notably, all mutations identified in TMEM94 were predicted to result in truncated proteins lacking the highly conserved C-terminal domain and exhibited a significant decrease in TMEM94 expression1. Recently, it has been reported that TMEM94 may also be implicated in overgrowth-intellectual disability3 and pancreatic adenocarcinoma4. Despite some advancements in the pathological aspect, the structural and functional mechanisms of TMEM94 remain enigmatic. Recently, TMEM94 was identified as the long-awaited endoplasmic reticulum (ER) Mg2+ ATPase and plays an indispensable role in facilitating Mg2+ uptake into the ER. Consequently, to reflect its newfound function, TMEM94 has been officially renamed as ER magnesium ATPase (ERMA)5. However, several scientists have challenged these findings through bioinformatic analysis6. The determination of whether TMEM94 is a distinct P-type ATPase or not necessitates further...Read more...

DARPA smashes wireless power record, beaming energy more than 5 miles away

 The U.S. military has set a new record for wireless power transmission, beaming a laser carrying more than 800 watts of power across a distance of 5.3 miles (8.6 kilometers). The test, performed by the U.S. military's Defense Advanced Research Projects Agency (DARPA) as part of its Persistent Optical Wireless Energy Relay (POWER) program, is a key step toward unlocking the near-instant beaming of power. It also smashes previous records set by the POWER program, which previously beamed 230 watts across 1 mile (1.7 km) for 25 seconds, and a smaller, undisclosed amount of power as far as 2.3 miles (3.7 km).

Decline of Christianity in the U.S. has slowed, may have leveled off

 After many years of steady decline, the share of Americans who identify as Christians shows signs of leveling off – at least temporarily – at slightly above six-in-ten, according to a massive new Pew Research Center survey of 36,908 U.S. adults. The Religious Landscape Study (RLS) is the largest single survey the Center conducts, aiming to provide authoritative figures on the size of U.S. religious groups because the U.S. census does not collect that information.

How Americans view Elon Musk and Mark Zuckerberg

 Americans’ views of two prominent tech executives – Elon Musk and Mark Zuckerberg – tilt more negative than positive. Musk is a deeply polarizing figure, with Republicans largely viewing him favorably and Democrats largely unfavorably. By contrast, views of Zuckerberg are less polarized, with majorities in both parties viewing him unfavorably.

Just over half of U.S. adults (54%) say they have an unfavorable view of Musk, including 36% who have a very unfavorable opinion of him. About four-in-ten (42%) express a favorable view, including 11% who are very favorable, according to a Pew Research Center survey conducted Jan. 27-Feb. 2, 2025. Read more...

Kidney function is associated with the rate of cognitive decline in the elderly

 In mixed-effects models adjusted for age, sex, and education, a lower eGFR at baseline was associated with a more rapid rate of cognitive decline (estimate 0.0008, SE <0.001, p = 0.017). The increased rate of cognitive decline associated with a 15-mL/min/1.73 m2 lower eGFR at baseline (approximately 1 SD) was similar to the effect of being 3 years older at baseline. Impaired kidney function at baseline was associated with a more rapid rate of cognitive decline (estimate −0.028, SE <0.009, p = 0.003). The increased rate of cognitive decline associated with impaired kidney function at baseline was approximately 75% the effect of ApoE4 allele on the rate of cognitive decline. Baseline kidney function was associated with declines in semantic memory, episodic memory, and working memory but not visuospatial abilities or ... Read more...

The link between local news coverage and Americans’ perceptions of crime

For most of the past three decades, Americans have said crime is rising in the United States, even though official statistics show a dramatic decrease in crime during that span. In 23 of 27 Gallup surveys conducted since 1993, at least 60% of Americans have said there is more crime in the U.S. than there was the year before. But this perception is at odds with the data: Since 1993, the nation’s violent crime rate has plunged by nearly half, while the property crime rate has fallen even more steeply, according to the FBI. Put another way, Americans were about twice as likely to be the victim of a violent crime in 1993 as in 2022. There are many possible reasons why Americans might believe crime is on the rise in the U.S., even when government statistics show the opposite. But a new Pew Research Center survey examines one potential factor shaping public perceptions: local news coverage about crime. The survey is from the Pew-Knight Initiative, a research program funded jointly by The Pew Charitable Trusts and the John S. and James L. Knight Foundation. Here are some of the key findings from the...Read more...

At what age do we age the most?

 Humans age dramatically at two key points in their life, study finds

Scientists have found that human beings age at a molecular level in two accelerated bursts – first at the age of 44, and then again at 60. In a study published in the journal Nature Aging, scientists at Stanford University and Nanyang Technological University in Singapore followed 108 participants over several years to observe aging changes in their molecules — RNA, proteins and participants’ microbiomes. The scientists found that human aging does not happen in a gradual, linear way. Rather, the majority of the molecules they studied showed accelerated, non-linear changes at the ages of 44 and 60.

Xiaotao Shen, an assistant professor in microbiome medicine at Nanyang Technological University and first author of the study, told CNN that the results show “we are not becoming old gradually.” Some points in time are particularly important for our aging and health, he added. For example, the ability to metabolize caffeine notably decreases – first around the age of 40 and once more around 60. Components involved in metabolizing alcohol also diminish, particularly around the age of 40, Michael Snyder, chair of the department of genetics at Stanford and an author of the study, told CNN, referring to the two waves of...Read more...

Unlocking the Promise of Digital Twins

 Imagine a hospital where a doctor is reading test results from two cancer patients. One is a 62-year-old woman, who sits in the exam room waiting to discuss her treatment options. The other is her virtual representation — a set of simulations and models that mimic the patient and the tumor. Together, the real-world patient, her virtual counterpart, and the flow of information between the two form a system called a digital twin.

Results from imaging or lab tests on the patient update the virtual representation, which feeds into simulations of how the patient’s body might respond to different potential therapies. Doctors could use such insights to minimize invasive testing on already weary and sick patients, and to develop personalized care plans that avoid unnecessary treatments — simultaneously making patients’ lives easier, optimizing the outcomes, and reducing health care costs. Over the past several years, advancements in digital twin technologies — which use modeling and simulation to create a virtual representation that mimics the structure, context, and behavior of its physical counterpart — means this scenario is coming closer to being realized. Going beyond traditional simulation and modeling, digital twins feature bidirectional feedback — think of it as a continuous back and forth chatter — between their virtual and...Read more...

Basic income can double global GDP while reducing carbon emissions, analysis suggests

 Giving a regular cash payment to the entire world population has the potential to increase global gross domestic product (GDP) by 130%, according to a new analysis published June 7 in the journal Cell Reports Sustainability. Researchers suggest that charging carbon emitters with an emission tax could help fund such basic income programs while reducing environmental degradation. "We are proposing that if we can couple basic income with environmental protection, we can save two birds with one stone," says first author U. Rashid Sumaila of the University of British Columbia in Vancouver. Sumaila has been working on ending harmful fishery subsidies worldwide, but many people who rely on fisheries for their livelihoods, especially those in developing countries, say they...Read more...

Texas passes a bill becoming the first state in the nation to make Juneteenth an official state holiday

 A celebration that has persisted for over a century receives its first official recognition on June 7, 1979, as the Texas Legislature passes a bill declaring Juneteenth a state holiday. The annual June 19 celebration of the Emancipation Proclamation—not the announcement itself, but the arrival of the news of the proclamation in Texas—is now officially observed in almost all 50 states. President Abraham Lincoln’s Emancipation Proclamation officially freed the enslaved peoples of the rebellious Southern states on New Year’s Day of 1863, but the order only applied to territories currently held by the Confederacy. Southerners did not recognize Lincoln’s authority, and in many cases slaveowners and whites simply withheld the news from enslaved people. The wait was especially long in Texas, where news of...Read more...

New rare 'green bean' galaxy discovered

 Astronomers from New Mexico State University (NMSU) and elsewhere report the discovery of a new galaxy of a rare class, dubbed "green bean." The finding, made with the Karl G. Jansky Very Large Array (VLA), was presented in a research paper published May 29 on the preprint server arXiv.

The so-called "green beans" are very rare active galaxies glowing green under the intense radiation from the region around a central black hole. To date, only 17 such galaxies have been identified by the Sloan Digital Sky Survey (SDSS). Astronomers suppose that their rare occurrence is due to the fact that these sources may be experiencing a short-lived phase in their evolution.

Now a team of astronomers, led by NMSU's Kelly N. Sanderson, has detected another galaxy of this rare type. Using VLA, they have observed a source in the sky with extended radio emission, designated RGZ J123300.2+060325. Previous studies of this source, which is at a redshift of approximately 0.3, suggested that it may be a...Read more...

How the Southern economic model denies prosperity to all

Summary: The Southern economic development model has failed to create shared prosperity in the region. In fact, this model was deliberately designed to do the opposite—to extract the labor of Black and brown Southerners as cheaply as possible. This report examines the racist roots of the model and provides the necessary context to challenge the enduring racial hierarchy in the South. 

Many states across the Southern United States utilize an economic development model that prioritizes business interests and the wealthy over ordinary citizens. This model—which we refer to as the “Southern economic development model”—is defined by low wages, low taxes, few regulations on businesses, few labor protections, a weak safety net, and fierce opposition to unions. This model is marketed as the way to attract businesses into the region, with the implicit promise that this will generate an abundance of jobs and shared economic prosperity for all Southerners.

In reality, this economic development model is fundamentally flawed as a strategy for improving living conditions for most Southerners. In fact, the Southern economic development strategy was never designed to help the vast majority of working Southerners; rather, it reflects efforts to ensure continued access to the cheap labor of Black people following emancipation, and that of Black and brown people more generally today. 

In this report, we describe the Southern economic development model in detail and document the historical evolution of various components of the model. We show how politicians and the wealthy across the South have used racism and drawn on notions of white supremacy to divide the population along racial, ethnic, nativist, and economic lines. This has prevented Southerners from coming together in solidarity to demand policies that would uplift everyone in the...Read more...
