Planetary exploration missions on the surface of Mars are carried out with great care. Communication delays between Earth and robotic spacecraft can range from 4 to 22 minutes, adding further constraints due to limited data transmission capacity. This requires scientists to carefully plan each step in advance. The rover is also designed to conserve energy and avoid danger, moving slowly over rough terrain. Most only move a few hundred meters a day, which limits the amount of terrain they can explore and makes it difficult to collect extensive geological data. Researchers sought new strategies designed to overcome these limitations. They…
The public’s concerns about the ubiquitous man-made chemicals known as per- and polyfluoroalkyl substances (PFAS) are finally reflected in bipartisan legislation in the Virginia General Assembly. Several different bills are currently awaiting action from Gov. Abigail Spanberger by April 13th. These include requirements for industrial users to test wastewater for PFAS and for wastewater treatment plants to test sludge for the presence of these contaminants before applying it to agricultural land. The enactment of the law does not mean that the problem of the notorious “eternal chemicals” that accumulate in the body and cause various diseases has been solved. neurological…
Supporters of a bill to regulate “plug-in solar” in New Hampshire believe the device would democratize access to the Granite State’s shining solar energy in a time of energy uncertainty. But they also said they wanted to tread carefully to avoid potentially dangerous pitfalls. “What the sponsors of this bill really mean is to give people who don’t have community solar coverage, who don’t own a home, or who can’t afford heavy rooftop solar, the opportunity to generate electricity and save money,” he said. Dover Democratic Sen. David Watterson monday. Also known as “portable solar,” this device consists of a…
Although quantum computers have great promise, they are still far from reliable. Their biggest weakness is instability, which quickly corrupts the information they process. Researchers around the world, including a research team in Norway, are working to solve this problem. “In quantum computers, information is transmitted and stored using so-called quantum bits (qubits). However, quantum information can be quickly lost,” said Professor Jeroen Danon from the Department of Physics at the Norwegian University of Science and Technology (NTNU). Why do quantum computers lose information? A key challenge is understanding exactly how quickly this information disappears. Without that knowledge, it is…
New evidence suggests that common viral infections may shape dementia risk, while vaccination and antiviral therapy may offer a surprising route to prevention. Research: Does herpesvirus contribute to dementia? Insights from infections, antiviral treatments, and vaccinations.

In 2023, scientists detected subatomic particles called neutrinos hitting Earth at energy levels that seemed impossible. No known cosmic process can generate so much energy. The particles carried about 100,000 times more energy than anything ever produced by the Large Hadron Collider, the most powerful particle accelerator on Earth. Now, physicists at the University of Massachusetts Amherst think they may have found an explanation. Their ideas involve the explosive death of a rare type of black hole known as a “subextremal primordial black hole.” Clues to the deepest secrets of the universe In a study published in physical review letterresearchers…
The United States could face foreign attacks, food shortages and agricultural “devastation” if the U.S. Supreme Court rules against Monsanto in a high-profile case over pesticide regulation scheduled for argument later this month, according to a series of legal briefs supporting Monsanto. By contrast, opponents’ legal briefs warn that if the court sides with Monsanto, consumers will be stripped of their right to sue if they develop cancer or other serious illnesses caused by exposure to dangerous chemicals. They warn that companies will be able to hide the risks of their products with little accountability. A high-profile case before the…
A famous 300 million-year-old fossil once believed to be the oldest octopus ever discovered has been reclassified after new analysis reveals it to be something entirely different. This specimen was even included in the Guinness Book of World Records, but scientists now say this distinction is based on a misunderstanding. This confusion goes back to events that occurred long before fossils were formed. The animal’s body changed hundreds of millions of years ago as it decomposed, and later began to resemble an octopus when it was preserved in rock. Revealing hidden teeth with advanced image processing The researchers used state-of-the-art…
Researchers have developed a powerful new method to map how brain cells are connected by tagging neurons with molecular ‘barcodes’. Using this technique, they were able to graph thousands of neural connections in the mouse brain with incredible speed and detail. This method has the potential to improve our understanding of how complex brain networks are organized and how they function. It may also shed light on what’s wrong with neurological diseases and how diseases like Alzheimer’s disease develop over time. “When you design a computer, you need to know the circuitry of the central processing unit. If you don’t…
Every second, countless electrical charges pass through the human body. These subtle signals are essential to life. They facilitate communication between cells, enable energy production, and support metabolism. None of these work without the carefully controlled movement of charge across the cell membrane and within the cell. In many ways, charge transport serves as a fundamental control system in biology. Phosphoric acid (H3PO4) and related compounds are present almost ubiquitously in biological systems. They are important components of DNA and RNA, part of cell membranes, and the center of ATP, the molecule that stores and transfers energy within cells. These…
