A recent advancement in quantum communication technology has seen scientists develop an exceptionally bright light source capable of generating quantum-entangled photons. This innovation holds significant promise for the future of secure and high-speed quantum communications. Published on 24 July in the journal eLight, the study reveals how combining existing technologies has led to the creation

Tensions between Brazil and Elon Musk’s business empire ratcheted up further as the country’s telecoms regulator threatened to sanction his satellite broadband company Starlink hours after its top court stood behind a controversial decision to ban social network X from the country. Brazil’s President Luiz Inacio Lula da Silva also backed the top court’s Judge
Glaciers have long served as nature’s deep freezers, preserving the physical characteristics of past climates and the genetic blueprints of ancient life forms, including viruses. As the planet’s climate continues to shift, scientists are increasingly looking to these frozen archives to understand how pathogens have historically responded to environmental changes. By studying viral genomes extracted
NASA has announced that Boeing’s Starliner capsule, which is currently docked at the International Space Station (ISS), will return to Earth without astronauts on board. The undocking is scheduled for September 6, 2024, at 6:04 p.m. EDT, with the capsule expected to land in White Sands Space Harbor, New Mexico, six hours later. This mission
Archaeologists have uncovered a 2,500-year-old astronomy observatory in Buto, Egypt, believed to be the largest of its kind from the sixth century BCE. The discovery was made during an excavation of a temple complex dedicated to Wadjet, the protector goddess of Lower Egypt. The observatory, which spans a quarter of an acre (850 square metres),
Extreme heat waves are not only a growing threat to humans but also to vital pollinators like bumble bees. A recent study published in the Proceedings of the Royal Society B reveals that heat waves can significantly impair bumble bees’ ability to detect the scents of flowers they depend on for food. This discovery raises
For the first time, scientists have successfully detected and measured an invisible electric field enveloping Earth. This field, known as the ambipolar field, was first theorised over 60 years ago and its discovery marks a significant advancement in our understanding of Earth’s atmospheric dynamics. Glyn Collinson, an astronomer at NASA‘s Goddard Space Flight Center, and
In 2023, scientists discovered subtle ripples in the fabric of spacetime, known as gravitational waves, originating from pulsar timing arrays. These low-frequency waves were initially thought to be the result of a phase transition that occurred shortly after the Big Bang. However, new research has cast doubt on this explanation, suggesting that our understanding of
For the first time in history, a NASA-funded researcher will accompany their experiment on a commercial suborbital rocket. This milestone will take place aboard Blue Origin’s New Shepard suborbital rocket system, which is scheduled to launch no earlier than Thursday, August 29. The experiment, developed by a team from the University of Florida in Gainesville,
A significant portion of the Atlantic Ocean near the equator experienced a rapid and unprecedented cooling over the summer months, leaving scientists puzzled about the cause. While the temperatures in the area have started to climb back to normal levels, the reasons behind this sudden drop remain unclear. The cold patch, which appeared in early
Researchers from IIT Guwahati and the Indian Space Research Organisation (ISRO) have made a surprising discovery that could reshape our understanding of X-ray pulsars. They found that the X-rays emitted by Swift J0243.6+6124, the first known Galactic Ultraluminous X-ray Pulsar, exhibit an unexpectedly low level of polarization. This pulsar, which is located within our galaxy,
Astronomers have achieved a significant breakthrough with new high-resolution images of Polaris, also known as the North Star. Using the CHARA Array located on Mount Wilson in California, researchers have captured unprecedented details of the star’s surface. This is the first time scientists have been able to observe features such as large bright and dark
Recent research reveals that human brains can survive for an astonishingly long time, with some specimens enduring for up to 12,000 years. Alexandra L. Morton-Hayward, a forensic anthropologist at the University of Oxford, led a study that uncovered over 4,400 instances of preserved human brains across various archaeological sites. This finding challenges the notion that
NASA’s Perseverance rover has embarked on a critical phase of its mission on Mars, beginning its challenging ascent towards the summit of Jezero Crater. This marks a new chapter in the rover’s exploration, which has been ongoing since 2021. After spending three and half years studying the crater’s floor—a region that was once submerged under
NASA is grappling with a significant challenge as two US astronauts, Sunita Williams and Barry Wilmore, find themselves stranded aboard the International Space Station (ISS). Initially scheduled for an eight-day mission, their return has now been delayed to February due to technical problems with Boeing’s Starliner spacecraft, which was supposed to bring them back to
A recent study has revealed that SARS-CoV-2, the virus responsible for the COVID-19 pandemic, might be using an unexpected method to infect the brain. Researchers found that mutations in the virus’ spike protein allow it to enter brain cells through a “back door,” a process that might explain the neurological symptoms observed in some COVID-19
Physicists have recently observed an unexpected phenomenon in a superconducting material, potentially pushing the boundaries of what’s possible in this field. The discovery centres on a material typically known as an electrical insulator. In this insulator, researchers found that electrons could pair up at temperatures as high as minus 123 degrees Celsius (minus 190 degrees
Scientists are making significant strides toward potentially adding a new element to the periodic table. Currently, the table includes 118 elements, each with a distinct number of protons in its nucleus. For example, hydrogen has one proton, while oganesson has 118. The quest to explore the limits of atomic physics has led researchers to focus
Two NASA astronauts who flew to the International Space Station (ISS) in June aboard Boeing’s faulty Starliner capsule will need to return to Earth on a SpaceX vehicle early next year, NASA officials said on Saturday, deeming issues with Starliner’s propulsion system too risky to carry its first crew home as planned. Veteran NASA astronauts Butch
New research suggests that peculiar zones in the Earth’s mantle, where seismic waves slow dramatically, may be more common than previously thought. These ultra-low velocity zones (ULVZs) have intrigued scientists for years due to their ability to slow seismic waves by up to 50 percent. Recent findings indicate that these enigmatic features could be present
