He said he'd do it - and he did.


Billionaire, innovator and always the controversial CEO, Elon Musk scratched together over 40 billion dollars and has taken the reigns of social media giant Twitter.


But now that thew deed is done - a lot of people have some concerns about Musk's intentions for the platform and its hundreds of thousands of users.


Will there be an edit button?

Will there finally be an end to 'bots'?

And what about moderation and free speech?


These are all valid and important questions to ask, and that's why Michigan State University's Anjana Susarla penned a recent piece in The Conversation to tackle those topics.



What lies ahead for Twitter will have people talking and reporters covering for the days and weeks to come.  And if you're a journalist looking for insight and expert opinion - then let us help with your stories.

New study reveals how corals teach their offspring to beat the heat

Why this matters: Warming ocean temperatures are causing a phenomenon called coral bleaching, putting corals at a greater risk of starvation, disease and death. This study shows that rice coral, an important reef-building species, passes on thermal resistance to their offspring and avoids coral bleaching. Understanding this is important to building healthier coral reefs and protecting their future. Coral reefs are habitats for nearly a quarter of all marine life, protect coasts from erosion and support the livelihoods of millions. Protecting coral reefs is crucial to preserving the future of our oceans. Plunge into the shallows off the Florida Keys, Hawaiʻi or the Great Barrier Reef in Australia and you are likely to meet a startling sight. Where there were once acres of dazzling coral — an underwater world of dayglo greens, brassy yellows and midnight blues — is now a ghostly landscape, with many reefs seemingly drained of their pigment. Caused by stressful conditions like warming ocean temperatures, coral bleaching is a leading threat to some of our planet’s most diverse and vital ecosystems. Now, a team of researchers has found that some corals survive warming ocean temperatures by passing heat-resisting abilities on to their offspring. The findings, published in the journal Nature Communications, are the result of a collaboration between Michigan State University, Duke University and the Hawaiʻi Institute of Marine Biology, or HIMB, at the University of Hawaiʻi at Mānoa. This work, funded by the National Science Foundation and a Michigan State University Climate Change Research grant, is crucial in the race to better conserve and restore threatened reefs across the globe. Coral reefs are habitats for nearly a quarter of all marine life, protecting coastlines from storms and erosion and supporting the livelihoods of millions of people around the world. Though still alive, bleached corals are at a much higher risk of disease, starvation and eventual mortality. In their latest study, the team explored how resistance to thermal stress is passed down from parent to offspring in an important reef-building species known as rice coral. These findings are helping researchers breed stronger, heat-tolerant generations to better face environmental stress. “The Coral Resilience Lab in Hawaiʻi has developed amazing methods to breed and rear corals during natural summer spawning,” said Spartan biochemist and study co-author Rob Quinn, whose lab takes samples of these corals and generates massive datasets on their biochemistry with instruments at MSU. “This is a true scientific collaboration that can support coral breeding and reproduction to cultivate more resilient corals for the warming oceans of the future.” A colorful crowd The kaleidoscopic of shades we associate with healthy coral is the product of a bustling exchange of resources between a coral animal and its algae partners. When all is well, you might think of this relationship as that of tenants living in a home and paying a bit of rent. In exchange for cozy, sheltered spaces found within the coral tissue as well as nutrients, algae use photosynthesis to produce sugars. These sugars can provide up to 95% of the energy that coral needs to grow and form the sprawling, breathtaking reefs we know. In tropical waters often lacking nutrients, disruptions in this exchange — like those that occur during bleaching events — can be disastrous. When looking at a specimen of coral that’s suffered bleaching, you’re glimpsing a coral that’s “kicked out” its algae, leaving behind a pale skeleton. “Corals are like the trees in an old growth forest; they build the ecosystems we know as reefs on the energetic foundation between the animal and algae,” explained Crawford Drury, an assistant researcher at the Coral Resilience Lab at HIMB and co-author of the study In the waters of Kāneʻohe Bay, the Coral Resilience Lab is spearheading research to best understand this coral reef ecology and the molecular mechanisms driving thermal stress. The lab is likewise pioneering the breeding of thermally resistant coral for experiments and the restoration of reefs, a highly specialized process few labs in the world can achieve. So, while you’d usually be hard pressed to find fresh coral for study in East Lansing, MSU’s partnership with the Coral Resilience Lab has led to a globe-spanning collaboration that closes the gap between field and laboratory. “HIMB and MSU have developed a really amazing partnership. I’m just happy they’ve let me be a part of it. I can’t wait to see what comes out of it next,” said Ty Roach, a visiting faculty at Duke University and lead author of the new study. Heat-resistant hand-me-downs In the wild, rice coral takes on a dizzying array of shapes, from jutting, spiky protrusions to flat, tiered terraces — all identifiable by the tiny grain-like projections that lend the species its name. When samples arrive at MSU, Quinn applies an analytical approach known as metabolomics to understand the complex biochemistry of the organisms. Like a snapshot of life in motion, metabolomics allows researchers to get an idea of what’s occurring within a cell or tissue sample at a precise moment in time. Leveraging advanced instrumentation found in MSU’s Mass Spectrometry and Metabolomics Core, the team searched for biochemical signatures associated with bleaching resistance in their samples. This included analyzing coral sperm, eggs, embryos and larvae, as well as their algal “collaborators.” Through their analyses, the researchers discovered that both coral and algae pass along the biochemical signature of thermal tolerance, and that this tolerance was successfully maintained from parent coral into the next generation. Given rice coral’s method of reproduction and the numerous stages of the coral life cycle, this was an impressive feat. “Corals usually spawn based on the lunar cycle; for our experiment, this means late nights around the summer new moons and months of work rearing coral larvae and juveniles,” said Drury. This summer, Quinn group graduate student Sarah VanDiepenbos had the chance to join Coral Resilience Lab researchers to witness one such nighttime coral spawning and breeding event. “It was such a serene, beautiful experience. The timing is impeccable, as the process only lasts 20 to 30 minutes total,” VanDiepenbos explained. “The coral bundles slowly float upward, trying to find another gamete to combine with once they get to the surface. This release is gradual, so they can have a maximum chance of finding spawn from a different coral,” she added. Tougher genes for warmer seas While many species of corals uptake symbionts from the surrounding seawater, rice coral provide their eggs with algae, handing this relationship down from parent to child. “To have this algae’s thermal tolerance remain through an entire generation and all the stages of coral development, that’s surprising, and promising for the future of coral reefs,” Quinn said, who’s also an associate professor in MSU’s Department of Biochemistry and Molecular Biology. Especially compelling was the fact that the earliest stages of the coral lifecycle, like embryos and larva, showed chemical signatures linked to whether parent organisms were thermally tolerant or not. This means that not only do offspring receive heat-resistant genes, but also beneficial molecules to give them a head start against heat stress. “Some of the most interesting findings from this work is that coral lipid biochemistry is maintained through all stages of development during reproduction,” Quinn said. “Importantly, these lipids come from both the host coral and its algal symbiont, indicating there is crosstalk between them to prepare the next generation to resist bleaching,” he added. In showing how inherited thermal resistance originates from both coral and algae, this research provides deeper insight into the finely tuned, symbiotic microcosm found in corals across the world’s oceans. Most exciting for the team is how these findings are contributing to the science behind the restoration of reefs and the breeding of stronger, more heat-tolerant coral generations. “Our metabolomics research at MSU could support reef restoration efforts at places like the Kāneʻohe Bay by identifying corals that are resistant to bleaching,” Quinn said.

MSU team develops scalable climate solutions for agricultural carbon markets

Why this matters: Builds trust in carbon markets. This science-based baseline system dramatically improves accuracy, helping ensure carbon credits are credible and truly reflect climate benefits. Enables real climate impact by accounting for both soil carbon and nitrous oxide emissions, the approach delivers a full, net climate assessment. Scales across millions of acres. Tested on 46 million hectares in 12 Midwest states, this approach is ready for large-scale adoption, helping farmers transition to regenerative practices with confidence and clarity. New research from Michigan State University, led by agricultural systems scientist Bruno Basso, addresses a major problem in agricultural carbon markets: how to set an accurate starting point, or “baseline,” for measuring climate benefits. Most current systems use fixed baselines that don’t account for the soil carbon changes and emissions that would occur if business-as-usual practices were maintained on fields. Such inaccuracies can distort carbon credit calculations and undermine market trust. “The choice of baseline can dramatically influence carbon credit generation; if the model is inaccurate, too many or too few credits may be issued, calling market legitimacy into question,” said Basso, a John A. Hannah Distinguished Professor in the Department of Earth and Environmental Sciences, the Department of Plant, Soil and Microbial Sciences and the W.K. Kellogg Biological Station at MSU. “Our dynamic baseline approach provides flexible scenarios that capture the comparative climate impacts of soil organic carbon, or SOC, sequestration and nitrous oxide emissions from business-as-usual practices and the new regenerative system.” The research, published in the journal Scientific Reports, covers 46 million hectares of cropland across the U.S. Midwest, provides carbon market stakeholders with a scalable, scientifically robust crediting framework. It offers both the investment-grade credibility and operational simplicity needed to expand regenerative agriculture. Regenerative agriculture and carbon markets Regenerative agriculture includes practices like cover cropping, reduced or no tillage, diversified rotations, adaptive grazing and agroforestry. These methods restore soil health, enhance biodiversity, increase system resilience and help mitigate climate change by building SOC and reducing greenhouse gas emissions. Carbon markets offer a promising financial mechanism to accelerate regenerative transitions. By compensating farmers for verified climate benefits, they can act as either offset markets (for external buyers) or inset markets (within agricultural supply chains). However, the integrity of these markets hinges on reliable, science-based measurement, reporting and verification systems that integrate modeling, field data and remote sensing. A breakthrough multi-model ensemble approach To overcome limitations in traditional modeling, the MSU scientists and colleagues from different institutions in the U.S. and Europe deployed a multi-model ensemble, or MME, framework, using eight validated crop and biogeochemical models across 40,000 locations in 934 counties spanning 12 Midwestern states. The MME avoids model selection bias, lowering uncertainty in soil carbon predictions from 99% (with single models) to just 36% (with the MME). “This is a game changer for carbon markets,” said Basso. “It delivers a level of accuracy and scalability — from individual fields to entire regions — that current systems lack.” The MME platform also enables the creation of precalculated, practice-based dynamic baselines, reducing the burden of data collection and easing participation for producers. Improved mitigation assessments Unlike many approaches that consider only SOC, the MSU lead team’s study evaluates both SOC sequestration and nitrous oxide emissions to determine net climate impact. “This comprehensive assessment ensures that carbon credits represent true climate mitigation,” said Tommaso Tadiello, postdoctoral fellow in MSU’s Department of Earth and Environmental Sciences and co-author of the study. “A practice that increases soil carbon may improve soil health,” added Basso, “but it may not deliver actual climate benefits if it simultaneously increases nitrous oxide emissions. Our method provides a full accounting of the net climate effect.” The research team found that the combination of no-till and cover cropping delivered an average net mitigation of 1.2 metric tons of carbon dioxide-equivalent per hectare annually, potentially abating 16.4 teragrams of carbon dioxide-equivalent across the study area. This research was supported by the Michigan Department of Agriculture and Rural Development, U.S. Department of Energy’s Great Lakes Bioenergy Research Center, National Science Foundation Long-Term Ecological Research, Builders Initiative, The Soil Inventory Project, Generation IM Foundation, Walton Family Foundation, Morgan Stanley Sustainable Solutions Collaborative and MSU AgBioResearch.

Ask the expert: The constituencies who will determine Michigan’s election results

When it comes to how Michigan has voted in modern presidential elections, a majority of voters have voted for the Democratic nominee for president. In recent years, however, Michigan has become more competitive as a key swing state. In 2016, former President Donald Trump won by just over 10,000 voters and in 2020 President Joe Biden won by just over 150,000 voters. After Vice President Kamala Harris replaced President Biden as the Democratic nominee, she has had a thin lead over Trump and, now, many pundits are saying Michigan is a toss-up. For Harris to win the presidency, she likely must carry Michigan and that includes needed margins with key voter groups such as young voters, as well as Arab American and Black voters. Nazita Lajevardi is an associate professor in the Department of Political Science in the College of Social Science. She is an expert in American politics, and her work focuses mainly on issues related to race and ethnic politics, political behavior, voting rights and immigration. Here, she answers questions on key groups of voters and the issues they care about that could determine who wins Michigan — and likely who will win the presidency. Responses and excerpts are from an article published in Brookings. Where does the election stand in the final days? Since Biden stepped down at the end of July, Harris has enjoyed a steady — albeit at times uncomfortably thin — lead over Trump in Michigan. However, polling from the end of September onward suggests that Harris comfortably winning the state on Nov. 5 is not a foregone conclusion. With just three weeks left to go in the 2024 presidential race, the polling website FiveThirtyEight indicates that as of Oct. 24, 2024, Kamala Harris is ahead of Donald Trump in Michigan by only 0.6 points — 47.6 compared to 47.0. This narrowing of the race appears to be closing the gap that Harris gained over Trump in August. Diving deeper into specific polls feeding into these estimates, it becomes clear that while Harris maintained a solid and consistent lead over Trump by between one and up to eight percentage points in the middle half of September, polls from the third week of September onward have either had Trump leading the state, Harris winning the state by a slim margin, or the two of them being evenly split. What issues do Michigan voters care about? A September 2024 New York Times/Siena College poll found that the three issues Michigan voters cared most about were the economy (24%), abortion (17%) and immigration (14%). Trump, for one, has campaigned heavily in recent weeks about two of these three issues. For instance, he has appealed heavily to Michiganders whose jobs were lost to globalization and automation by promising to revive the American car industry and bring back car factories that have closed in recent years. Groups like Duty to America are highlighting Trump’s strengths on illegal immigration by airing ads across Michigan arguing that it has hurt white people who have been “left behind.” And, while Harris, on the other hand, has great strengths on abortion rights, success in the 2022 elections in amending the state constitution to secure the right to abortion and other reproductive health services may have reduced abortion’s importance as a central voting issue in the state. What impact will Black voters have on Michigan’s result? Among Black voters, experts have identified an enthusiasm gap between those who are part of the “Black leadership class” and deeply connected to the Democratic Party and those Black Michiganders without those same connections, who are more working class, poorer, more fatigued, less interested, and therefore more susceptible to sitting out elections. Many Black voters are also deeply concerned about the economy, and as Michigan State University political scientist Meghan Wilson has noted, Harris could attract Black business owners and holders of student debt by discussing plans to infuse capital into small businesses. The Harris campaign appears to agree. Recently, Harris not only unveiled economic proposals appealing to Black voters but also traveled to Detroit to participate in a radio town hall with Charlamagne tha God, whose program The Breakfast Club has a nationwide audience, much of whom is Black. But attention should be paid to one particular effort to stifle Black turnout. Recently, it was revealed that Tom Barrett, a GOP candidate for the U.S. House, ran a newspaper advertisement in the Black-owned newspaper Michigan Bulletin that incorrectly informed the readership, most of whom are Black, to vote on Nov. 6, when Election Day is Nov. 5. What impact will Arab American voters have on Michigan’s result? Harris is in a deeply precarious position vis-à-vis Michigan’s Muslim and Middle East/North Africa, or MENA, electorates. Without a doubt, these groups will have an outsized impact in deciding how Michigan’s 15 electoral college votes will be cast. According to political scientist Youssef Chouhoud, Michigan is home to more than 200,000 Muslim registered voters. Over the past year, Muslims’ support for the Democratic Party has plummeted. In a recent poll fielded between Aug. 25 and Aug. 27, the Council on American Islamic Relations found that Jill Stein is leading Muslim voters in Michigan; 40% of Muslims surveyed in that poll supported Stein, 18% supported Trump and only 12% supported Harris. And, as Harris’ support for Israel remains steadfast while Israel continues its assaults on Gaza and now Lebanon, she has arguably alienated these voters who could have been a reliable source of electoral support for her. What will the role of youth voters be in Michigan’s outcome? Young voters in Michigan present a potential stream of untapped support for the Democratic Party. Though young voters have historically turned out at lower rates than older Americans, young voters in Michigan stand out from their peers. Fifty-four percent of Michiganders 18 to 29 years old voted in the 2020 election, a 20% increase from 2016. In the 2022 midterms, when young voters aged 18 to 29 in Michigan recorded the highest voter turnout in all the country, they demonstrated how impactful their votes were in enshrining abortion and voting rights in the state constitution. That year, about 75% of students who were registered voters at the University of Michigan and Michigan State University cast ballots. This year, however, how successful Harris has been in activating the youth vote remains to be seen. Certainly, young Michiganders are more enthusiastic about her candidacy than they were Biden’s, but recent analyses by Michigan State University political scientist Corwin Smidt indicate that so far youth turnout in Michigan’s November 2024 election lags behind their 2020 levels. What’s more, young voters were a key part of the “uncommitted” coalition who sent a strong message to then presidential nominee Biden over his enabling of the Israeli war in Gaza during the February 2024 primary election. But Harris is making strides to connect with young voters by establishing offices at campuses across the state. Importantly, young voters could not only shape the outcome of the presidential election, but also the partisan balance in Congress, given that young voters at Michigan State University will have the opportunity to cast a ballot in the race for Michigan’s 7th Congressional District, which is among the 26 toss-up districts in the country.
