The sun is the basis for photosynthesis, but not all plants thrive in strong sunlight. Strong sunlight constrains plant diversity and plant biomass in the world's grasslands, a new study shows. Temperature, precipitation, and atmospheric nitrogen deposition have less impact on plant diversity. These results were published in the Proceedings of the National Academy of Sciences by a research team led by Marie Spohn from the Swedish University of Agricultural Sciences.

From fundamental biological units as tiny as genes to complex societies, ecological systems rely on cooperation. All manner of organisms can benefit from working together to survive in a dog-eat-dog world. "Mutualism is a common example of interspecies cooperation," says Utah State University ecologist Valerie Martin. "Scientists have long studied mutualisms between plants and pollinators, but understanding their origin and maintenance remains a challenge. Curiously, exploitative behaviors—including cheating—are rampant among mutualists and we're trying to understand why."

The nuclear envelope (NE) is a dynamic and selective barrier that organizes genome function and nucleocytoplasmic communication, and its structural deterioration is a hallmark of aging associated with diverse human diseases. Now, researchers from the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences (CAS) have uncovered a previously unrecognized mechanism by which mitochondrial redox signaling preserves the NE structure and delays aging.

The human kidney filters about a cup of blood every minute, removing waste, excess fluid, and toxins from it, while also regulating blood pressure, balancing important electrolytes, activating Vitamin D, and helping the body produce red blood cells. This broad range of functions is achieved in part via the kidney's complex organization. In its outer region, more than a million microscopic units, known as nephrons, filter blood, reabsorb necessary nutrients, and secrete waste in the form of urine.

A new genetic study examines an unusually large hybridization event that followed the Fukushima nuclear accident, when escaped domestic pigs bred with wild boar. The research shows that domestic pig maternal lineages sped up generational turnover, rapidly diluting pig genes. The findings reveal a mechanism likely operating wherever feral pigs and wild boar interbreed.

About a year ago, researchers at the University of Michigan found that the extratropical cyclones that are the biggest drivers of winter weather in the Great Lakes region are warming and trending northward. That means, outside of the northern reaches of the region, residents can expect that their winters will be warmer and wetter on average.

How did the complexity of many organisms living today evolve from the simpler body plans of their ancestors? This is a central question in biology. Take our hands, for example: Every time we type a message on our mobile phone, we are using an evolutionary "masterpiece" that evolved over millions of years. Notably, we typically grasp and manipulate objects with the palm of our hand—its ventral side. The back of our hand, or dorsal side, plays almost no role. This differentiation of our limbs, with a ventral side adapted for contact and a dorsal side protected by nails or toenails, is essential for life on land.

Around the Balkan Peninsula, the African plate is sinking beneath the European plate. A piece of deeply submerged African crust resurfaced 40 million years ago far away from the sinking zone. How this phenomenon of so-called vertical extrusion can be explained and whether the Rhodope mountain range in southern Bulgaria was formed in this way is a matter of scientific debate. Dr. Iskander Muldashev and Professor Thorsten Nagel from the TU Bergakademie Freiberg have now shown how this process works in a recent publication in the journal Geology. The formation of the Rhodopes was only 40 million years ago—the mountain range is therefore 30–50 million years younger than previously assumed.

Methane is a powerful greenhouse gas with strong heat-trapping capabilities. Although there is less methane in the atmosphere than carbon dioxide, the foremost greenhouse gas, researchers attribute 30% of modern global warming to methane. Observations show that methane levels have increased over time, but the factors driving changes in the rate of accumulation remain unclear.

A new smart platform invented by Purdue University researchers to wirelessly monitor subsoil health could change the landscape of agricultural sensing systems. The invention addresses a critical need in agriculture nationwide: the efficient use of water, fertilizers and pesticides. Due to the variability of soil conditions across large fields, applying uniform amounts of these inputs can lead to significant waste, increasing costs for farmers and causing environmental harm if nutrient runoff reaches water systems.

A new study conducted at the Potsdam Institute for Climate Impact Research (PIK) shows that grassland-based grazing systems—currently covering a third of Earth's surface and representing the world's largest production system—will see a severe contraction as global temperatures rise. Depending on the scenario analyzed, 36–50% of the land with suitable climatic conditions for grazing today will experience a loss of viability by 2100, affecting more than 100 million pastoralists and up to 1.6 billion grazing animals.

Many ecologists hypothesize that, as global warming accelerates, change in nature must speed up. They assume that as temperatures rise and climatic zones shift, species will face local extinction and colonize new habitats at an ever-increasing rate, leading to a rapid reshuffling of ecological communities. A new study by researchers at Queen Mary University of London (QMUL) and published in Nature Communications shows this is emphatically not the case.

For many years, the deep ocean has been seen as a nutrient-poor environment where microbes living in the water survive on very limited resources. But new research from the University of Southern Denmark (SDU) challenges that idea. A study led by SDU-biologists at the Department of Biology shows that nutrients might not be so sparse after all in the deep and that microbes have access to a hitherto unknown source of dissolved organic food.

On Friday, Feb. 6, the U.S. Army Corps of Engineers released the final version of its Environmental Impact Statement on Enbridge’s proposed Line 5 tunnel project, starting a 30 day waiting period before making its final decision on whether to grant the pipeline company a permit to move forward with the proposal.

Canada-based Enbridge celebrated the release of the statement as a true milestone, with spokesperson Ryan Duffy praising the six-year review as “thorough, transparent, and science driven.” However, Line 5 opponents argue the final document fails to address several key concerns, including the project’s impacts on Indigenous treaty rights and alternatives for transporting oil outside of the Great Lakes.

The Line 5 tunnel project would replace the segment of dual pipelines operating in the Straits of Mackinac – where Lake Michigan and Lake Huron meet – with a new, single segment housed in a tunnel in the bedrock beneath the lakes.

The 645-mile long pipeline runs from Northwestern Wisconsin, through Michigan where it ends in Sarnia, Ontario. It carries up to 22.68 million gallons of crude oil and natural gas liquids through the Straits of Mackinac each day.

Julie Goodwin, a senior attorney for Earthjustice, which is supporting the Bay Mills Indian Community in its fight against the pipeline, said the final environmental impact statement sets up a predetermined decision to approve the tunnel by failing to consider scenarios where oil is not flowing through the straits.

In its review, the corps looked at four main scenarios: taking no action and allowing the dual pipelines to continue operating, constructing a tunnel beneath the lakebed as Enbridge would prefer, placing a gravel/rock protective cover over the dual pipelines, and replacing the dual pipelines with a new segment installed using horizontal directional drilling under the lakebed.

“The corps had the opportunity, of course, during this environmental review process to look at alternatives that transport oil outside of the Great Lakes region or in different ways. And they just, they never took that opportunity,” Goodwin said.

A 2016 study from the University of Michigan determined more than 700 miles of shoreline in lakes Huron and Michigan would be vulnerable to pollution should Line 5 rupture. A 2018 study published by Michigan State University determined that the economic damage from a Great Lakes oil spill would amount to $5.6 billion dollars.

While the environmental impact statement acknowledges the straits are a profoundly sacred place in the culture, history and spirituality of Anishinaabe Tribal Nations, it does not address the tunnel project’s impact on treaty rights, which grant tribal nations the right to hunt, fish and gather on lands ceded to the federal government.

The corps writes that its review of treaty rights is separate from its review of the project under the National Environmental Policy Act and that it is consulting on a government-to-government basis with federally recognized Tribes to determine if the tunnel project would infringe upon treaty rights. The final finding will be included in its record of decision.

On March 21, 2025, Bay Mills Indian Community alongside the Little River Band of Ottawa Indians, Sault Ste. Marie Tribe of Chippewa Indians, Grand Traverse Band of Ottawa and Chippewa Indians, Match-E-Be-Nash-She-Wish Band of Pottawatomi, and Nottawaseppi Huron Band of the Potawatomi sent a letter to the Army of Corps of Engineers withdrawing their participation as cooperating agencies in drafting the environmental impact statement, due to President Donald Trump’s Administration’s plan to expedite review of the tunnel project.

The Little Traverse Bay Bands of Odawa Indians similarly withdrew from talks with the corps on March 26.

Whitney Gravelle, president of the Bay Mills Indian Community, said it has been frustrating to watch the corps move forward with the environmental impact statement without completing surveys and research on cultural resources and treaty rights.

“That’s one of the reasons we left as a cooperating agency,” Gravelle said. “The corps has disregarded tribes. They’ve disregarded tribal treaty rights, they’ve disregarded cultural resources, and it has just been one of the most dehumanizing processes I have ever participated in.”

The tunnel itself will bore through several cultural sites, archaeological resources and what Anishinaabe consider to be the site of creation, Gravelle said and there are hundreds if not thousands of archaeological sites on the north and south ends of the straits.

“Those burial places are how we understand our history, how we understand our culture, how we understand our trade movements, or where we’re meant to be harvesting, hunting and gathering,” Gravelle said. “To then be told that all of these places can be destroyed and that it doesn’t really matter, what you’re really saying is that our Indigenous lifeways then don’t matter.”

Gravelle emphasized that the impacts from the tunnels construction are not abstract or theoretical, telling Michigan Advance that these places are where parents go to teach their children ceremony on the water, uncles teach their families how to hunt and put food on the table and elders share stories so their community can understand who they are as a people.

“To have those rights limited or overlooked or misunderstood is really undermining the impact that will be felt by generations,” Gravelle said. “Not only by myself, but by my niece, you know, by my children, by the generations that will exist long after I’m gone from this earth.”

In a statement, Sean McBrearty, the campaign coordinator for anti-Line 5 Oil & Water Don’t Mix coalition pointed to several of the environmental impacts included within the assessment.

“The EIS confirms that the tunnel would result in permanent wetland loss and require excavation and removal of roughly 665,000 cubic yards of bedrock from beneath the Straits of Mackinac, the ecological heart of the Great Lakes system,” McBrearty said. “These impacts are not temporary, and they cannot be undone.”

While much of the focus on Line 5 has centered around the Straits of Mackinac, Gravelle noted that concerns about an oil spill stretch the length of the pipeline, which has leaked more than 30 times over its lifespan, spilling more than 1 million gallons of oil.

However, Gravelle and several other pipeline opponents emphasized that a permitting decision from the Army Corps of Engineers does not give Enbridge a green light to move forward with the project, as the Michigan Department of Environment, Great Lakes and Energy has yet to decide on a Clean Water Act permit for the project. The Sierra Club and Oil and Water Don’t Mix have already called on Gov. Gretchen Whitmer to block the project from moving forward.

“All eyes are really turning to Governor Whitmer,” Goodwin said. “She has two choices to either cave to the Trump administration’s agenda and their friends in the oil industry, or stand up for Michigan and protect the Great Lakes.”
