Hurricane season officially begins June 1, and now is the time to get ready for potential storms. Hurricane Preparedness Week, observed May 4 to 10, is a reminder for Louisiana residents to review their emergency plans, strengthen their homes, and prepare their families before a major storm arrives.
“Preparedness saves lives, protects property and reduces recovery time,” said Carol Friedland, director of the LSU AgCenter LaHouse Research and Education Center. “By taking a few proactive steps now, families can be better protected during hurricane season.”
Even though hurricane season does not begin for another month, starting your preparation now can save time and hassle later. The following are good projects you can start in the coming weeks to prepare for severe weather:
Create and practice a family emergency plan and make sure it has updated contact information and evacuation information.
Assemble an emergency supply kit or go through your existing kit to make sure nothing is expired or missing. Update it to make sure your entire family, including your pets, will have supplies during an evacuation. Review insurance coverage and understand flood risks. Some companies or policies have a waiting period before your coverage begins, so contact your agent or representative now. Strengthen your home against high winds and flooding. Do an overview of your home’s exterior and note any areas that look like they need repairs, like patches of missing shingles. Repairing these smaller problems now can reduce the likelihood of your home experiencing more severe damage during a storm. “Taking the time to check your home and yard early and getting bigger projects or repairs started ahead of hurricane season can save you a lot of stress later, especially when materials become harder to find right before a storm,” said Rubayet Bin Mostafiz, assistant director of research at LaHouse.
Don’t wait until a storm is in the forecast. Start preparing today.

As temperatures warm up across Louisiana, so does termite activity. Homeowners may soon begin to notice large swarms of winged insects in and around their homes. These are termite alates, also known as swarming termites.
“Swarming is how termites establish new colonies,” said LSU AgCenter entomologist Aaron Ashbrook. “Seeing swarms around your home doesn’t necessarily mean you have an infestation, but it does mean termites are nearby.”
Alates are the reproductive members of a future termite colony if they can successfully establish. Each spring, usually following a warm rain, these termites leave their established colonies to find new places to nest. Many alates are produced because a low percentage of them are able to establish a colony. After swarming, they shed their wings and pair off to begin new colonies, which is how they end up in homes.
Louisiana’s warm, humid climate makes it an ideal environment for termites, especially the Formosan subterranean termite, one of the most destructive species in the United States. Termites can silently cause thousands of dollars in damage before homeowners know they’re there.
Tips for homeowners: Don’t panic, but don’t ignore it. Seeing swarms outside is common, but if they're inside your home, call a licensed pest control professional. Look for signs. Discarded wings, mud tubes, water stains, moisture buildup, and soft or hollow-sounding wood can all indicate a problem. Reduce moisture. Termites thrive in damp environments and require moist wood to attack structures. Fix leaks and ensure proper drainage around your home. Schedule regular inspections. Annual termite inspections are recommended, especially in high-risk areas like Louisiana. “Termites can cause extensive structural damage to your home that may go unnoticed,” said Carol Friedland, director of LaHouse Research and Education Center. “Early detection and prevention can save homeowners a lot of stress and money.”

BATON ROUGE – Since the Big Bang, the early universe had hydrogen, helium, and a scant amount of lithium. Later, some heavier elements, including iron, were forged in stars. But one of the biggest mysteries in astrophysics is: How did the first elements heavier than iron, such as gold, get created and distributed throughout the universe? A new answer has come from an unexpected place – magnetars.
Neutron stars are the collapsed cores of stars that have exploded. They are so dense that one teaspoon of neutron star material, on Earth, would weigh as much as a billion tons. A magnetar is a neutron star with an extremely powerful magnetic field.
On rare occasions, magnetars release an enormous amount of high-energy radiation when they undergo “starquakes,” which, like earthquakes, fracture the neutron star’s crust. Starquakes may also be associated with powerful bursts of radiation called magnetar giant flares, which can even affect Earth’s atmosphere. Only three magnetar giant flares have been observed in the Milky Way and the nearby Large Magellanic Cloud, and seven from other nearby galaxies.
Astrophysicist Eric Burns and his team of researchers at Louisiana State University in Baton Rouge study magnetars extensively through the observation of gamma-rays. These are the most energetic photons, most famous for turning Bruce Banner into the Incredible Hulk.
Burns joined with researchers at Columbia University and other institutions to see if we could use gamma-rays to understand if magnetar giant flares forge the heaviest elements, and unexpectedly found the smoking-gun signature in decades-old data. The study, led by Anirudh Patel, a doctoral student at Columbia University in New York, is published in The Astrophysical Journal Letters.
“It’s answering one of the questions of the century and solving a mystery using archival data that people had just forgotten about, demonstrating something that occurred when the Universe was younger,” said Burns. “Giant flares should occur just after the first stars died, meaning we have identified what could be the origin of the first gold in the universe.”
How could gold be made at a magnetar? Patel and colleagues, including his advisor Brian Metzger, Professor at Columbia University and senior research scientist at the Flatiron Institute in New York, have been thinking about how radiation from giant flares could correspond to heavy elements forming there. This would happen through a “rapid process” of neutrons forging lighter atomic nuclei into heavier ones.
Protons define the element’s identity on the periodic table: hydrogen has 1 proton, helium has 2, lithium has 3, and so on. Atoms also have neutrons which do not affect identity, but do add mass. Sometimes when an atom captures an extra neutron the atom becomes unstable and a nuclear decay process happens that converts a neutron into a proton, moving the atom forward on the periodic table. This is how, for example, a gold atom could take on an extra neutron and then transform into mercury.
In the unique environment of a disrupted neutron star, in which the density of neutrons is extremely high, something even stranger happens: single atoms can rapidly capture so many neutrons that they undergo multiple decays, leading to the creation of a much heavier element like uranium.
When astronomers observed the collision of two neutron stars in 2017 using NASA telescopes and the gravitational wave observatory LIGO, they confirmed that this event could have created gold, platinum, and other heavy elements. “LIGO tells us there was a merger of compact objects, and Fermi tells us there was a short gamma-ray burst. Together, we know that what we observed was the merging of two neutron stars, dramatically confirming the relationship,” said Burns. But neutron star mergers happen too late in the universe’s history to explain the earliest gold and other heavy elements.
Finding secrets in old data At first, Metzger and colleagues thought that the easiest signature to study from the creation and distribution of heavy elements at a magnetar would appear in the visible and ultraviolet light, and published their predictions. But Burns in Louisiana wondered if there could be a gamma ray signal bright enough to be detected, too. He asked Metzger and Patel to work out what that signal could look like.
Burns looked up the gamma ray data from the last giant flare that was observed, which was in December 2004. He realized that while scientists had explained the beginning of the outburst, they had also identified a smaller signal from the magnetar, in data from ESA (European Space Agency)’s INTEGRAL, a retired mission with NASA contributions. “It was noted at the time, but nobody had any conception of what it could be,” Burns said.
Metzger remembers that Burns thought he and Patel were “pulling his leg” because the prediction from their team’s model so closely matched the mystery signal in the 2004 data. In other words, the gamma ray signal detected over 20 years ago corresponded to what thought it should look like when heavy elements are created and then distributed in a magnetar giant flare.
"This is my favorite discovery I've contributed to,” said Burns. “My colleagues found this signal in the past, but nobody knew what it could be at the time. Once these models were ready, everything fit like a perfect puzzle, which is extremely rare in science."
Researchers supported their conclusion using data from two NASA heliophysics missions: the retired RHESSI (Reuven Ramaty High Energy Solar Spectroscopic Imager) and the ongoing NASA Wind satellite, which had also observed the magnetar giant flare. Other collaborators on the new study included Jared Goldberg at the Flatiron Institute.
Next steps in the magnetar gold rush Patel’s study estimates that magnetar giant flares could contribute about 10% of the total abundance of elements heavier than iron in the galaxy. Since magnetars existed relatively early in the history of the universe, the first gold could have been created this way.
LSU PhD candidate Aaron Trigg, a NASA FINESST (Future Investigators in NASA Earth and Space Science and Technology) fellow, who works with Burns, is responsible for finding more magnetar giant flares to study. “These are gargantuan outbursts of energy from the strongest magnets in the Universe, which are powerful enough to affect Earth’s atmosphere,” said Burns. Trigg’s work will help us better understand these sources.”
NASA’s forthcoming COSI (Compton Spectrometer and Imager) mission can follow up on these results. COSI, a wide-field gamma ray telescope, is expected to launch in 2027 and will study energetic phenomena in the cosmos, such as magnetar giant flares. COSI will be able to identify individual elements created in these events, providing a new advancement in understanding the origin of the elements.
LSU is one of the lead science institutes for COSI. Burns and LSU Assistant Professor Michela Negro have key responsibilities in the mission, and Trigg is working through how best to study giant flares with COSI. These LSU astrophysicists will be growing their research group as they approach launch in 2027.
“I have so many questions about the cosmos and our place in it,” said Trigg. “This research allows me to explore those questions and share the answers with the world.”
