Researchers hypothesize a fifth force of nature that could explain the intricate relationship between dark matter and dark energy, suggesting a revolutionary expansion of the Standard Model of physics.

Could a new, fifth force of nature help answer some of the biggest mysteries about dark matter and dark energy? Scientists are actively exploring the possibility.

The Standard Model of physics is widely regarded as one of the greatest achievements in modern science. It describes the universe’s four known forces — gravity, electromagnetism, and the strong and weak nuclear forces — as well as a diverse array of fundamental particles and their interactions. By many measures, it stands as one of the most successful scientific theories in history.

Scientists Solve Long-Standing DNA Machinery Mystery https://lifeboat.com/blog/2025/01/scientists-solve-long-standing-dna-machinery-mystery https://lifeboat.com/blog/2025/01/scientists-solve-long-standing-dna-machinery-mystery#respond Sun, 26 Jan 2025 16:23:20 +0000 https://lifeboat.com/blog/2025/01/scientists-solve-long-standing-dna-machinery-mystery

SMC proteins can reverse direction, reshaping DNA

DNA, or deoxyribonucleic acid, is a molecule composed of two long strands of nucleotides that coil around each other to form a double helix. It is the hereditary material in humans and almost all other organisms that carries genetic instructions for development, functioning, growth, and reproduction. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Scientists Recreate the Conditions That Sparked Complex Life https://lifeboat.com/blog/2025/01/scientists-recreate-the-conditions-that-sparked-complex-life https://lifeboat.com/blog/2025/01/scientists-recreate-the-conditions-that-sparked-complex-life#respond Sun, 26 Jan 2025 16:23:01 +0000 https://lifeboat.com/blog/2025/01/scientists-recreate-the-conditions-that-sparked-complex-life

Examples of endosymbiosis are everywhere. Mitochondria, the energy factories in your cells, were once free-living bacteria. Photosynthetic plants owe their sun-spun sugars to the chloroplast, which was also originally an independent organism. Many insects get essential nutrients from bacteria that live inside them. And last year researchers discovered the “nitroplast,” an endosymbiont that helps some algae process nitrogen.

So much of life relies on endosymbiotic relationships, but scientists have struggled to understand how they happen. How does an internalized cell evade digestion? How does it learn to reproduce inside its host? What makes a random merger of two independent organisms into a stable, lasting partnership?

Now, for the first time, researchers have watched the opening choreography of this microscopic dance by inducing endosymbiosis in the lab. After injecting bacteria into a fungus—a process that required creative problem-solving (and a bicycle pump)—the researchers managed to spark cooperation without killing the bacteria or the host. Their observations offer a glimpse into the conditions that make it possible for the same thing to happen in the microbial wild.

Einstein’s Theory Faces Its Heaviest Challenge Yet — and It Still Holds Up https://lifeboat.com/blog/2025/01/einsteins-theory-faces-its-heaviest-challenge-yet-and-it-still-holds-up https://lifeboat.com/blog/2025/01/einsteins-theory-faces-its-heaviest-challenge-yet-and-it-still-holds-up#respond Sun, 26 Jan 2025 06:23:39 +0000 https://lifeboat.com/blog/2025/01/einsteins-theory-faces-its-heaviest-challenge-yet-and-it-still-holds-up

Researchers at the Large Hadron Collider tested whether top quarks, the most massive known elementary particles, comply with Einstein’s theory of relativity.

Despite theories suggesting potential deviations at high energies, the experiments confirmed that Lorentz symmetry remains intact, offering no evidence of variation in particle behavior due to the experiment’s orientation or the time of day.

Lorentz Symmetry and Relativity.

A single-shot trick can boost the signal strength of tin-based qubits https://lifeboat.com/blog/2025/01/a-single-shot-trick-can-boost-the-signal-strength-of-tin-based-qubits https://lifeboat.com/blog/2025/01/a-single-shot-trick-can-boost-the-signal-strength-of-tin-based-qubits#respond Sun, 26 Jan 2025 06:23:25 +0000 https://lifeboat.com/blog/2025/01/a-single-shot-trick-can-boost-the-signal-strength-of-tin-based-qubits

However, until now, “measuring this qubit’s spin was like trying to pick up a very, very weak light signal, like trying to squint at some dim light to determine whether the qubit was spin-up or spin-down,” Eric Rosenthal, a postdoctoral scholar at Stanford University, said.

This is where a new study from Rosenthal and his team can make a big difference. They have figured out a way to measure the spin of tin-based qubits with 87 percent accuracy, enhancing the strength of signals from these qubits to a great extent.

A tin vacancy qubit is formed when two carbon atoms in a diamond are replaced by a single tin atom. This tin center has exceptional optical properties as it emits photons in the telecom wavelength range, which is highly suitable for quantum communication applications.

Scientists Discover Promising Molecule That Restores Cognitive Function in Early Alzheimer’s https://lifeboat.com/blog/2025/01/scientists-discover-promising-molecule-that-restores-cognitive-function-in-early-alzheimers https://lifeboat.com/blog/2025/01/scientists-discover-promising-molecule-that-restores-cognitive-function-in-early-alzheimers#respond Sat, 25 Jan 2025 20:23:53 +0000 https://lifeboat.com/blog/2025/01/scientists-discover-promising-molecule-that-restores-cognitive-function-in-early-alzheimers

A study by the University of the Basque Country (UPV/EHU) demonstrates that the drug WIN55,212–2 protects the brain and reverses early cognitive damage caused by dementia, while also explaining its mechanism of action.

Over two decades of research conducted by the Neurochemistry and Neurodegeneration group at UPV/EHU, led by Dr. Rafael Rodríguez-Puertas, has uncovered a promising pathway for developing therapies aimed at improving memory in cases of cognitive impairment caused by neurodegenerative diseases like Alzheimer’s.

Alzheimer’s disease is a progressive neurological disorder that primarily affects older adults, leading to memory loss, cognitive decline, and behavioral changes. It is the most common cause of dementia. The disease is characterized by the buildup of amyloid plaques and tau tangles in the brain, which disrupt cell function and communication. There is currently no cure, and treatments focus on managing symptoms and improving quality of life.

Clocking nature’s heaviest elementary particle: CMS tests whether top quarks play by Einstein’s rules https://lifeboat.com/blog/2025/01/clocking-natures-heaviest-elementary-particle-cms-tests-whether-top-quarks-play-by-einsteins-rules https://lifeboat.com/blog/2025/01/clocking-natures-heaviest-elementary-particle-cms-tests-whether-top-quarks-play-by-einsteins-rules#respond Sat, 25 Jan 2025 20:23:00 +0000 https://lifeboat.com/blog/2025/01/clocking-natures-heaviest-elementary-particle-cms-tests-whether-top-quarks-play-by-einsteins-rules

In the first study of its kind at the Large Hadron Collider (LHC), the CMS collaboration has tested whether top quarks adhere to Einstein’s special theory of relativity. The research is published in the journal Physics Letters B.

Along with , Einstein’s special theory of relativity serves as the basis of the Standard Model of particle physics. At its heart is a concept called Lorentz symmetry: experimental results are independent of the orientation or the speed of the experiment with which they are taken.

Special relativity has stood the test of time. However, some theories, including particular models of string theory, predict that, at very high energies, special relativity will no longer work and experimental observations will depend on the orientation of the experiment in space-time.
