Gulf of Mexico oil activity endangers Rice's whale, NOAA finds

E&E News21-05-2025

NOAA Fisheries has determined that oil and gas activities in the Gulf of Mexico could drive Rice's whale to extinction, unless regulators take new precautionary measures.
The agency released its revised biological opinion Tuesday, one day before a court-ordered deadline. The 677-page biological opinion replaces the old analysis, which a federal judge tossed out in 2024 for violating the Endangered Species Act.
There are only a few dozen Rice's whales left in the Gulf, which is their only habitat. NOAA Fisheries said its proposal, if followed, would make lethal vessel strikes 'extremely unlikely to occur' and would therefore sufficiently protect the species.

Valvular regurgitation: What You Need to Know

Valvular regurgitation is when blood flows backward through the chambers of your heart. It can be mild and not cause symptoms, or it can be life threatening. Your heart is a muscular organ that contains four chambers. Blood flows between these chambers and your lungs in a set pattern to distribute oxygen-containing blood to every organ in your body. Your heart also contains four valves that control blood flow through its chambers. Valvular regurgitation occurs when blood moves backward through one of these valves. The severity depends largely on the amount of blood that backflows and whether or not it is causing symptoms or other problems. Minor cases might not cause symptoms, whereas more severe cases may lead to issues such as shortness of breath or heartbeat abnormalities. Read on to learn more about valvular regurgitation, including types, potential symptoms, and causes. Types of valvular regurgitation Valvular regurgitation is named after the valve through which blood backflows through. Types include: Tricuspid valve regurgitation: Your tricuspid valve is found between your right atrium and right ventricle. Tricuspid valve regurgitation is characterized by the backflow of blood into your right atrium. Pulmonary valve regurgitation: Your pulmonary valve separates your right ventricle from the blood vessels supplying your lungs. Regurgitation can cause blood to flow back into your right ventricle from these blood vessels. Mitral valve regurgitation: Your mitral valve is found between your left atrium and left ventricle. Mitral valve regurgitation is characterized by the backflow of blood into your left atrium. Aortic valve regurgitation: The aortic valve is found between your left ventricle and your aorta, the large blood vessel that carries blood away from your heart. Aortic valve regurgitation causes blood to flow back into your left ventricle from your aorta. The most common type is mitral valvular regurgitation. What are the symptoms of valvular regurgitation? Symptoms of valvular regurgitation can range from non-apparent to severe. If your condition is caused by another condition, such as heart failure, your symptoms may get progressively worse over time. Symptoms may include: irregular heartbeat (arrhythmia) shortness of breath, which might be worse when lying flat new or worsening heart palpitations, which can cause heart: pounding fluttering whooshing swelling around your feet or ankles coughing feeling faint fatigue chest pain It's important to see your doctor if you experience any of these symptoms. Severe cases can lead to complications such as: heart failure arrhythmia (irregular heart rhythm) sudden cardiac arrest blood clots stroke pulmonary hypertension What are the causes of valvular regurgitation? Valvular regurgitation can develop due to congenital heart problems present from birth or develop secondary to other conditions affecting your heart. Tricuspid valve regurgitation: In adults, tricuspid regurgitation is usually secondary to other heart problems, such as cardiomyopathies. Cardiomyopathy is a disease of your heart muscle, and coronary artery disease is when plaque builds up in the blood vessels in your heart and restricts blood flow. Pulmonary valve regurgitation: The leading causes of pulmonary valve regurgitation in adults are pulmonary hypertension or congenital heart defects. Pulmonary hypertension is high blood pressure in the blood vessels connecting your heart and lungs. Mitral valve regurgitation: Primary mitral valve regurgitation can develop due to congenital heart defects, infections, and complications such as rheumatic heart disease, or connective tissue disorders such as Marfan syndrome or lupus. Secondary mitral valve regurgitation can develop due to conditions such as congestive heart failure or atrial fibrillation. Aortic valve disease: The two most common causes of aortic regurgitation are dilated aorta and bicuspid aortic valve. Calcified aortic stenosis is when your aortic valve thickens and narrows due to calcium buildup. How is valvular regurgitation treated? The treatment for valvular regurgitation depends on the underlying cause and severity. Mild cases might not need any treatment, but your doctor may still want to follow up regularly to ensure your condition doesn't progress. More severe cases may require medications or surgery to prevent and manage complications and symptoms. Medications Doctors may prescribe people with valvular heart disease many types of medications, such as the following: angiotensin converting enzyme (ACE) inhibitors or angiotensin II receptor blockers to open your blood vessels anti-arrhythmic medications to restore your heart rhythm antibiotics to prevent infections anticoagulants to reduce the risk of blood clots beta-blockers to help your heart beat slower diuretics to reduce the amount of fluid in your body vasodilators to reduce your heart's workload Surgery Severe cases of valvular regurgitation may require valve repair or valve replacement. These procedures may be performed through open-heart surgery or minimally invasive procedures, where your surgeon makes the repair or replacement through a small incision and special tools. These noninvasive procedures are catheter-based therapies. A cardiologist inserts the catheter into the blood vessels to reach the heart. Learn more about valve replacement surgery. Frequently asked questions Here are some frequently asked questions people have about valve regurgitation. What is meant by valve regurgitation? Valvular regurgitation is when a valve in your heart doesn't close completely, and blood flows backward into one of the chambers of your heart. It can also occur if blood flows back from the blood vessels leaving the heart, such as the aorta or pulmonary artery, back into the heart.

It can also occur if blood flows back from the blood vessels leaving the heart, such as the aorta or pulmonary artery, back into the heart. What is the life expectancy of a person with valvular regurgitation? The life expectancy for people with valvular regurgitation depends on factors such as the severity and other medical conditions. The life expectancy for people with valvular regurgitation depends on factors such as the severity and other medical conditions. How serious is valve regurgitation? If valve regurgitation is left untreated, it can be a serious problem, potentially leading to heart failure. It's important to seek medical attention if you suspect you may have heart valve regurgitation and follow up with any recommended treatment plans and tests.

Hundreds of scientists gather in Milwaukee to confront Great Lakes resilience challenges

Amid drastic cuts to science programs, grants and funding, Great Lakes scientists are converging in Milwaukee this week to talk about resilience – not just in the lakes, but science itself. More than 600 scientists from the U.S. and Canada are attending the International Association for Great Lakes Research week-long conference at Baird Center. The theme is creating Great Lakes resilience, which includes hundreds of presentations that cover topics like harmful blue-green algae blooms, coastal erosion, climate change and Indigenous knowledge. Rebecca Klaper, dean of the University of Wisconsin-Milwaukee School of Freshwater Sciences, said the conference is a way for scientists to talk about patterns, changes and solutions across the lakes. It's the first time in four decades the international conference is in Milwaukee. The conference rotates each year to a different city across the Great Lakes region, alternating between the U.S. and Canada. Harvey Bootsma, associate dean of UW-Milwaukee's School of Freshwater Sciences, said Milwaukee's deep connection to Lake Michigan and its three rivers made it a natural choice. He added that having one of the only graduate schools dedicated to freshwater science also helped draw the conference to the city. While the conference focuses on collaboration, growing uncertainty around Great Lakes research is top of mind for many as the Trump administration's proposed federal budget includes drastic cuts to science funding and programs. For instance, the National Oceanic and Atmospheric Administration, or NOAA, which supports a lot of research and long-term monitoring efforts in the Great Lakes, could see 25% of its budget cut from the proposed federal bill. Staffing cuts at the agency's Great Lakes lab in Michigan has already left much of the region's science efforts in limbo.

Klaper said many grants that support Great Lakes research have already been canceled. Universities are in a period of transition as they navigate how to adapt to shifting funding landscapes, Bootsma said. At the School of Freshwater Sciences, half of the revenue comes from overhead tied to research grants – money that supports basic operations like building maintenance. Losing that funding, he said, would have serious budget implications. "The current administration is driving science out of the U.S.," said Stephen Carpenter, the director of limnology at UW-Madison, adding that proposed budget cuts could slow U.S. progress as a leading nation in science. Despite funding concerns, researchers remain committed to protecting the Great Lakes. For many, the conference offers not just research opportunities, but inspiration and connection. Even with funding concerns, Kenneth Anderson, a post-doctoral researcher at Kent State University in Ohio, said he's motivated to keep his research going. 'As long as there are opportunities out there, we're going to be looking for ways to pursue them," Anderson said. More: Invasive mussels drastically altered the Great Lakes.
