It's possible to predict some violent public protests by tracking social media posts on moral outrage over a triggering event. Tracy Le Blanc/Pexels

Every grade school teacher knows that student conduct can get out of hand, fast, when a group of kids eggs on one individual. Time-outs are a testimony to the power of isolating one 10-year-old from a choir of buddies.

Social media plays a role similar to a gang of hyped-up grade schoolers, providing a community that can express collective disapproval of people or events. When this disapproval has a moral cast ⁠— for example, after a police shooting or the removal of a statue ⁠— the social network's particular characteristics are key predictors about whether that disapproval will turn violent.

There is a word for the way group support of a belief system makes it seem worth fighting for: moralization. Tracking social network activity now makes it possible to measure the chances for an individual belief to become moralized by a group ⁠— a phenomenon known as moral convergence.

In a recent study in Nature, Rice Business professor Marlon Mooijman, then at the Kellogg School of Management, joined a team that analyzed when and how violence erupts in protests. In a series of observation and behavior experiments that mixed psychology, organizational theory and computer science, they accurately predicted how violence is influenced by group discussion of moral views on social media.

The researchers started by studying the number and content of tweets linked to the Baltimore riots in 2015, after the death of Freddie Gray in police custody. The researchers then compared these tweets with the number of arrests in a given time frame, using a methodology developed by Marlon Mooijman and Joe Hoover from the Brain and Creativity Institute at the University of Southern California.

To analyze the tweets responding to Gray's death, they first separated them into two sets: Those with moral commentary and those without moral judgments.

Next, the researchers tracked whether tweets with moral content increased on days with violent protests. Violence was measured using the number of police arrests, which the researchers compared with the specific time frames of moral tweets.

There was no major difference in the overall tweet traffic discussing Freddie Gray's death on days with violent protests and on peaceful days. The number of moralizing tweets, however, clearly correlated with episodes of violent protests, rising to nearly double the moralizing tweets on days with no violence.

This raised a provocative question. Were morally ⁠— based tweets a response to the events of the day ⁠— or were they somehow driving the violence?

To find out, Mooijman and Hoover worked with computer scientists Ying Lin and Jeng Ji of Rensselaer Polytechnic Institute and Morteza Dehghani of the University of Southern California to develop algorithms that could establish mathematical probabilities for the results.

For every single-unit increase in moral tweets over a 4-hour period, the researchers found, there was a .25 corresponding increase in arrests.

The researchers then tried to measure the effect similar moral views ⁠— such as a social media page with self-selected members of a similar political affiliation ⁠— had on violence during protests.

To do so, they set up a second study, which measured participant reactions to the protestors of a far-right rally in Charlottesville, Virginia in 2017. Participants ranked their level of agreement over the morality of protesting the rally.

There was a direct relationship between believing a protest action was moral, the researchers found, and finding violence at that protest acceptable. This relationship held true throughout the study, regardless of political orientation.

The researchers' next goal was to identify the impact of exposure to people of like beliefs. To do this, participants rated their feelings when they were told that most people in the U.S. shared their views. While the intensity of participants' moral views created the potential for violence, the researchers found, violence resulted when only actively validated by others with similar views.

Having one's moral outrage supported by others on social media, the professors concluded, may explain the spike in violence in recent protests.

While respect for privacy remains critical, governments and law enforcement can use the social media trend to pinpoint the moments when moral outrage can turn deadly. Perhaps most importantly, however, the research also suggests practical tactics for calming violent tendencies before they get out of control. To reduce real-life protest violence, they wrote, it's critical that social media sites include a variety of voices. It's another reason, if any were needed, that a bit of judicious exposure to other views is healthy for everyone.

Rice University research shows the importance of coworker and leadership trust within businesses

Houston Voices

While U.S. soldiers battled in Vietnam, inside the White House, President Lyndon Johnson grew increasingly suspicious of those closest to him. The legendary political dealmaker now believed that any opposition to the war was part of a conspiracy against him; aides who questioned his policy might be part of it. According to research using newly available interviews and telephone transcripts, Johnson's distrust may have been triggered by the very experience of being in power.

But how, exactly? In a recent paper, Rice Business professor Marlon Mooijman and a team of colleagues delve deeply into the interaction of power and trust, seeking answers about when and why wielding power degrades leaders' belief in those around them.

The question has deep implications not only in politics, but also in business. "Managers must trust employees' willingness to comply with instructions and keep the company's best interest in mind," Mooijman notes. Without that trust, past research shows, workplace productivity, reciprocity and cooperation break down. Leaders who successfully craft trusting bonds with their coworkers and employees, on the other hand, are more effective than those who don't.

To learn why leaders might abandon that trust, Mooijman's team set up four studies. First, though, they had to establish a working definition of trust. Trust, they proposed, is the willingness to be vulnerable to another party's actions, based on the expectation that the other party will perform a specific action important to the truster — even without the truster's ability to monitor or control the activity. Essential to a trusting relationship: the expectation of the other party's goodwill, and the willingness to expose themselves to possible exploitation if that goodwill fails.

Whether you work in an indie coffee shop or a giant software company, most workers can name a leader who lacks that kind of trust. Many also have had the good luck of a leader who isn't lacking in that department. The difference between such managers, Mooijman's team found, may be the stability of their power.

There are plenty of reasons for wanting to keep power, obviously. In relationships, power holders are able to disregard others' wishes and pursue their own. Within the individual, power boosts self-esteem and encourages behaviors such as expressing amusement and happiness. Less obvious, however, is the effect of fearing a loss of power. Leaders whose power feels unstable experience this physically, with changes in heart rate and blood pressure. They have a heightened awareness of colleagues they perceive as threats, and are more prone to divide coworkers and disrupt their alliances.

When power holders or leaders perceive their power to be unstable, it's that prospect of power loss that erodes their trust in those around them, even helpful and often unsuspecting colleagues. So strong is this effect that it occurs even when the loss of power comes with an economic benefit, Mooijman notes. "Unstable power decreases trust," the team found, "regardless of whether we provided participants with a justification of their unstable position."

To reach their conclusions, Mooijman's team first surveyed 206 participants assembled through Amazon's Mechanical Turk software. Each participant was randomly assigned a power ranking (high or low) and asked to imagine being a VP of sales at a mid-sized firm. Some were told that as part of a productivity initiative they would be reassigned to other divisions. The participants were then asked to rank their perception of their power at their firm and their perception of their job stability there. Regardless of whether their job reassignment was explained or not, the researchers found, the participants who perceived their jobs — that is, their power — to be unstable showed more mistrust of their coworkers.

A final study, a field experiment with real life managers and subordinates, reinforced these findings. Managers in positions of relatively high power who perceived their jobs were unstable were more prone to voice distrust about their subordinates.

While instability is built into political careers, Mooijman's findings have practical implications in other industries. For example, the common practice of moving workers between departments, meant to build insight and productivity, may backfire. Instead of strengthening team spirit, the strategy will likely foment distrust. Similarly, at high levels of power, emphasizing job instability with tactics such as high-stakes, winner-take-all performance metrics might be counterproductive.

Power doesn't always erode trust, the researchers found. Leaders who felt their power was secure didn't show the same level of suspicion as those who felt their roles were insecure. But when power seems fragile, the research revealed, even the most seasoned leaders are prone to abandon trust in their colleagues and see work as a battlefield.

Houston researchers make headway on affordable, sustainable sodium-ion battery

Energy Solutions

A new study by researchers from Rice University’s Department of Materials Science and NanoEngineering, Baylor University and the Indian Institute of Science Education and Research Thiruvananthapuram has introduced a solution that could help develop more affordable and sustainable sodium-ion batteries.

The findings were recently published in the journal Advanced Functional Materials.

The team worked with tiny cone- and disc-shaped carbon materials from oil and gas industry byproducts with a pure graphitic structure. The forms allow for more efficient energy storage with larger sodium and potassium ions, which is a challenge for anodes in battery research. Sodium and potassium are more widely available and cheaper than lithium.

“For years, we’ve known that sodium and potassium are attractive alternatives to lithium,” Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor of Engineering at Rice, said in a news release. “But the challenge has always been finding carbon-based anode materials that can store these larger ions efficiently.”

Lithium-ion batteries traditionally rely on graphite as an anode material. However, traditional graphite structures cannot efficiently store sodium or potassium energy, since the atoms are too big and interactions become too complex to slide in and out of graphite’s layers. The cone and disc structures “offer curvature and spacing that welcome sodium and potassium ions without the need for chemical doping (the process of intentionally adding small amounts of specific atoms or molecules to change its properties) or other artificial modifications,” according to the study.

“This is one of the first clear demonstrations of sodium-ion intercalation in pure graphitic materials with such stability,” Atin Pramanik, first author of the study and a postdoctoral associate in Ajayan’s lab, said in the release. “It challenges the belief that pure graphite can’t work with sodium.”

In lab tests, the carbon cones and discs stored about 230 milliamp-hours of charge per gram (mAh/g) by using sodium ions. They still held 151 mAh/g even after 2,000 fast charging cycles. They also worked with potassium-ion batteries.

“We believe this discovery opens up a new design space for battery anodes,” Ajayan added in the release. “Instead of changing the chemistry, we’re changing the shape, and that’s proving to be just as interesting.”

TMC med-tech company closes $2.5M series A, plans expansion

fresh funding

Insight Surgery, a United Kingdom-based startup that specializes in surgical technology, has raised $2.5 million in a series A round led by New York City-based life sciences investor Nodenza Venture Partners. The company launched its U.S. business in 2023 with the opening of a cleanroom manufacturing facility at Houston’s Texas Medical Center.

The startup says the investment comes on the heels of the U.S. Food and Drug Administration (FDA) granting clearance to the company’s surgical guides for orthopedic surgery. Insight says the fresh capital will support its U.S. expansion, including one new manufacturing facility at an East Coast hospital and another at a West Coast hospital.

Insight says the investment “will provide surgeons with rapid access to sophisticated tools that improve patient outcomes, reduce risk, and expedite recovery.”

Insight’s proprietary digital platform, EmbedMed, digitizes the surgical planning process and allows the rapid design and manufacturing of patient-specific guides for orthopedic surgery.

“Our mission is to make advanced surgical planning tools accessible and scalable across the U.S. healthcare system,” Insight CEO Henry Pinchbeck said in a news release. “This investment allows us to accelerate our plan to enable every orthopedic surgeon in the U.S. to have easy access to personalized surgical devices within surgically meaningful timelines.”

Ross Morton, managing Partner at Nodenza, says Insight’s “disruptive” technology may enable the company to become “the leader in the personalized surgery market.”

The startup recently entered a strategic partnership with Ricoh USA, a provider of information management and digital services for businesses. It also has forged partnerships with the Hospital for Special Surgery in New York City, University of Chicago Medicine, University of Florida Health and UAB Medicine in Birmingham, Alabama.

2 Houston suburbs named among 10 best places to live by U.S. News & World Report

Where to Live

The Houston suburbs of Pearland and League City have landed among the top 10 best places to live in 2025, according to U.S. News & World Report.

New for the 2025-2026 "Best Places to Live in the U.S." rankings, U.S. News expanded its coverage from 150 to 250 U.S. cities, and updated its methodology to examine each city based on five livability indexes: Quality of life, value, desirability, job market, and net migration.

Pearland ranked No. 3 nationwide, earning a 7.0 score alongside No. 1-winning Johns Creek, Georgia and No. 2 winner Carmel, Indiana.

Pearland also landed on top of U.S. News separate rankings of the best places to live in Texas for 2025-2026.

Some facts about Pearland that put it at the top of the list include its median household income ($115,504), its median home values ($319,753), and its bustling population of nearly 124,000 residents.

Housing costs in Pearland are extremely attractive compared to other places in the country, as the national average home is worth over $370,000. It's no wonder this Houston neighbor has been adding more high-income households than many other places in Texas.

Pearland's population is a healthy mix of young individuals and families, with 29 percent of residents under 20 years old and 36 percent of the population between the ages of 20-44. Nearly a quarter of Pearland's population is between 45-64-years-old, while only 12 percent of residents are over 65, the report says.

Pearland's reputation as one of the safest cities in America is also boosting its community appeal.

"Finding a community to be part of can play a major role in making a place feel like home," U.S. News said. "If you’re a parent with young children, you may want to live in a neighborhood with other people in that phase of life. If you’re a professional moving to a hot job market for your field, you may want to live in an apartment close to the office or within walking distance of friends and colleagues."

Pearland also enjoys a better job market than other cities, the report added. Pearland's unemployment rate as of 2023 was only 3.6 percent, lower than the national average unemployment rate of 4.5 percent.

However, if people are looking for a public transportation-friendly city, they may need to look elsewhere. Almost all commuters in Pearland drive to their workplaces, making access to a vehicle absolutely necessary for living in the suburb. Pearland's 31.2-minute average commute time is also 9.2 minutes higher than the national average, U.S. News said.

Other Houston-area suburbs

League City ranked three spots behind Pearland as the 6th best place to live in the U.S., and No. 2 in Texas. The city boasts a median household income of $120,670, and affordable median home values at $327,511.

Workers in League City also predominantly rely on vehicles for their daily commutes, and only 3.7 percent of the population use public transport to get to work. Commuters spend an average time of 27.5 minutes driving to work, U.S. News determined.

More than half (63.5 percent) of all League City residents are married, and 54 percent of the population are between the ages of 25 and 64-years-old.

Here's how other Houston-area cities faired among the top 100:

  • No. 16 – Sugar Land
  • No. 44 – The Woodlands
  • No. 45 – Katy
  • No. 67 – Missouri City
  • No. 73 – Spring

Houston drops out of the top 100

Though Houston proper made substantial improvements to land among the top 100 best places to live in U.S. News' 2024-2025 report, the city has once again plummeted toward the bottom of the list for 2025-2026.

Houston slumped to No. 381 this year, and only ranked No. 63 in the statewide comparison, showing that the city has lost its charm in favor of its appealing suburban neighbors.

The top 10 best places to live in the U.S. are:

  • No. 1 – Johns Creek, Georgia
  • No. 2 – Carmel, Indiana
  • No. 3 – Pearland, Texas
  • No. 4 – Fishers, Indiana
  • No. 5 – Cary, North Carolina
  • No. 6 – League City, Texas
  • No. 7 – Apex, North Carolina
  • No. 8 – Leander, Texas
  • No. 9 – Rochester Hills, Michigan
  • No. 10 – Troy, Michigan
