Scientists have discovered a super-Earth, named TOI-715 b, located within the “conservative” habitable zone of a nearby red dwarf star.
This revelation has ignited the astronomical community with the potential of uncovering conditions that are suitable for life a mere 137 light-years from Earth.
The research, led by Georgina Dransfield at the University of Birmingham, represents a significant step forward in our quest to understand the conditions under which life might arise.
The British Antarctic Survey (BAS) said successful tests would allow the drones to undertake research such as surveying marine ecosystems and studying glaciers, while reducing CO2 emissions by approximately 90%.
The Windracers Ultra UAV (uncrewed aerial vehicle) is a twin-engine, 10-metre aircraft that can carry up to 100kg of cargo or sensors for distances of 1,000km and does not require a human pilot to take off, fly or land as it is equipped with a sophisticated autopilot system.
Unlike piloted Twin Otter aircraft, which are costly to operate and face logistical challenges in the extreme environment, the BAS said the “groundbreaking” unmanned drones are safer and “could enable dramatic increases in flight time”
An international team of astronomers have found a new and unknown object in the Milky Way that is heavier than the heaviest neutron stars known and yet simultaneously lighter than the lightest black holes known.
Using the MeerKAT Radio Telescope, astronomers from a number of institutions including The University of Manchester and the Max Planck Institute for Radio Astronomy in Germany found an object in orbit around a rapidly spinning millisecond pulsar located around 40,000 light years away in a dense group of stars known as a globular cluster.
Using the clock-like ticks from the millisecond pulsar they showed that the massive object lies in the so-called black hole mass gap.
But one question intrigued scientists: “What happens if fluid is sucked in through the arms: Does the device rotate, in what direction, and why?”
High-tech experiment to understand the fluid dynamics
In this new study, researchers from New York University conducted tests to better understand the dynamics of flowing fluids and their impact on sprinkler structures.
Most approved gene therapies today, including those involving CRISPR-Cas9, work their magic on cells removed from the body, after which the edited cells are returned to the patient.
This technique is ideal for targeting blood cells and is currently the method employed in newly approved CRISPR gene therapies for blood diseases like sickle cell anemia, in which edited blood cells are reinfused in patients after their bone marrow has been destroyed by chemotherapy.
A new, precision-targeted delivery method for CRISPR-Cas9, published in the journal Nature Biotechnology, enables gene editing on very specific subsets of cells while still in the body—a step toward a programmable delivery method that would eliminate the need to obliterate patients’ bone marrow and immune system before giving them edited blood cells.
A collaborative group of researchers has potentially developed a means of controlling spin waves by creating a hexagonal pattern of copper disks on a magnetic insulator. The breakthrough is expected to lead to greater efficiency and miniaturization of communication devices in fields such as artificial intelligence and automation technology.
Details of the study were published in the journal Physical Review Applied on January 30, 2024.
In a magnetic material, the spins of electrons are aligned. When these spins undergo coordinated movement, they generate a kind of ripple in the magnetic order, dubbed spin waves. Spin waves generate little heat and offer an abundance of advantages for next-generation devices.
Ancient concepts of the relational interdependence of humans and nature are being revived.
Basic biology textbooks will tell you that all life on Earth is built from four types of molecules: proteins, carbohydrates, lipids, and nucleic acids. And each group is vital for every living organism.
But what if humans could actually show that these “molecules of life,” such as amino acids and DNA bases, can be formed naturally in the right environment? Researchers at the University of Florida are using the HiPerGator—the fastest supercomputer in U.S. higher education—to test this experiment.
HiPerGator—with its AI models and vast capacity for graphics processing units, or GPUs (specialized processors designed to accelerate graphics renderings)—is transforming the molecular research game.
