An international research team including members from The University of Manchester has shown that a rapidly rotating neutron star is at the core of a celestial object now known as PSR J2039-5617 The international collaboration used novel data analysis methods and the enormous computing power of the citizen science project Einstein@Home to track down the […]

The Venus flytrap (Dionaea muscipula) is a carnivorous plant that encloses its prey using modified leaves as a trap. During this process, electrical signals known as action potentials trigger the closure of the leaf lobes. An interdisciplinary team of scientists has now shown that these electrical signals generate measurable magnetic fields. Using atomic magnetometers, it […]

It was previously thought that collisions between galaxies would necessarily add to the activity of the massive black holes at their centers. However, researchers have performed the most accurate simulations of a range of collision scenarios and have found that some collisions can reduce the activity of their central black holes. The reason is that […]

A remarkable prediction of Einstein’s theory of general relativity — the theory that connects space, time, and gravity — is that rotating black holes have enormous amounts of energy available to be tapped. For the last 50 years, scientists have tried to come up with methods to unleash this power. Nobel physicist Roger Penrose theorized […]

Earth just got 7 km/s faster and about 2000 light-years closer to the supermassive black hole in the center of the Milky Way Galaxy. But don’t worry, this doesn’t mean that our planet is plunging towards the black hole. Instead the changes are results of a better model of the Milky Way Galaxy based on […]

Chemists at Scripps Research have made a discovery that supports a surprising new view of how life originated on our planet.In a study published in the chemistry journal Angewandte Chemie, they demonstrated that a simple compound called diamidophosphate (DAP), which was plausibly present on Earth before life arose, could have chemically knitted together tiny DNA […]

The core mass of the giant exoplanet WASP-107b is much lower than what was thought necessary to build up the immense gas envelope surrounding giant planets like Jupiter and Saturn, astronomers at Université de Montréal have found. This intriguing discovery by Ph.D. student Caroline Piaulet of UdeM’s Institute for Research on Exoplanets (iREx) suggests that […]

It is well known that the expansion of the universe is accelerating due to a mysterious dark energy. Within galaxies, stars also experience an acceleration, though this is due to some combination of dark matter and the stellar density. In a new study to be published in Astrophysical Journal Letters, researchers have now obtained the […]

On a cold winter day in December 2007, a bulldozer flattened nearly 40 acres (16 hectares) of Inner Mongolia’s Tengger Desert. It was the start of a unique experiment: For the first time, scientists would watch Earth’s winds give birth to dunes. Four years later, results from the giant Mongolian sandbox confirmed long-held models of […]

Galaxies begin to “die” when they stop forming stars, but until now astronomers had never clearly glimpsed the start of this process in a far-away galaxy. Using the Atacama Large Millimeter/submillimeter Array (ALMA), in which the European Southern Observatory (ESO) is a partner, astronomers have seen a galaxy ejecting nearly half of its star-forming gas. […]

In a study published in the chemistry journal Angewandte Chemie, they demonstrated that a simple compound called diamidophosphate (DAP), which was plausibly present on Earth before life arose, could have chemically knitted together tiny DNA building blocks called deoxynucleosides into strands of primordial DNA. The finding is the latest in a series of discoveries, over […]

Thousands of scientists gathered in Washington, D.C. Sunday for a five-day conference that has been billed as the “Super Bowl of astronomy.” The 223rd meeting of the American Astronomical Society (AAS) begins Sunday (Jan. 5) and runs through Friday (Jan. 9). Conference organizers are anticipating a big turnout.“We’re expecting more than 3,000 attendees, but probably […]

The Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) is home to many interdisciplinary projects which benefit from the synergy of a wide range of expertise available at the institute. One such project is the study of black holes that could have formed in the early universe, before stars and galaxies […]

Although violent and unpredictable, stellar flares emitted by a planet’s host star do not necessarily prevent life from forming, according to a new Northwestern University study. Emitted by stars, stellar flares are sudden flashes of magnetic imagery. On Earth, the sun’s flares sometimes damage satellites and disrupt radio communications. Elsewhere in the universe, robust stellar […]

By monitoring the cosmos with a radio telescope array, an international team of scientists has detected radio bursts emanating from the constellation Boötes — that could be the first radio emission collected from a planet beyond our solar system.The team, led by Cornell postdoctoral researcher Jake D. Turner, Philippe Zarka of the Observatoire de Paris […]

New digital techniques have allowed researchers to predict structural evolution of the skull in the lineage of Homo sapiens and Neanderthals, in an effort to fill in blanks in the fossil record, and provide the first 3D rendering of their last common ancestor. The study suggests populations that led to the lineage split were older […]

Many genetic mutations in visual pigments, spread over millions of years, were required for humans to evolve from a primitive mammal with a dim, shadowy view of the world into a greater ape able to see all the colors in a rainbow. Now, after more than two decades of painstaking research, scientists have finished a […]

Islamabad: Humans have taken spiders into space more than once to study the importance of gravity to their web-building. What originally began as a somewhat unsuccessful PR experiment for high school students has yielded the surprising insight that light plays a larger role in arachnid orientation than previously thought. The spider experiment by the US […]

Islamabad: Our solar system hosts a cornucopia of worlds, from the hellfire of Venus to the frozen plains of Mars to the mighty winds of Uranus. In that range, the Earth stands alone, with no planet coming close to its life-friendly position near the Sun. Outside our solar system, however, it’s a different story. Observations […]

Islamabad: Astronomers are still searching for a hypothetical “Planet Nine” in the distant reaches of our solar system, but an exoplanet 336 light years from Earth is looking more and more like the Planet Nine of its star system.Planet Nine, potentially 10 times the size of Earth and orbiting far beyond Neptune in a highly […]

Islamabad: Since astronomers confirmed the presence of planets beyond our solar system, called exoplanets, humanity has wondered how many could harbor life. Now, we’re one step closer to finding an answer. According to new research using data from NASA’s retired planet-hunting mission, the Kepler space telescope, about half the stars similar in temperature to our […]

Islamabad: New work led by Carnegie’s Matt Clement reveals the likely original locations of Saturn and Jupiter. These findings refine our understanding of the forces that determined our Solar System’s unusual architecture, including the ejection of an additional planet between Saturn and Uranus, ensuring that only small, rocky planets, like Earth, formed inward of Jupiter. […]

Islamabad: What do mercury levels in dolphins say about mercury levels in humans? Quite a bit, according to a new study by scientists at FAU Harbor Branch, which sheds light on the potential dangers of consuming locally caught seafood. This is the first time that researchers have closed the loop between marine mammal and human […]

Islamabad: The MPG/ESO 2.2-metre telescope at ESO’s La Silla Observatory in Chile has captured a richly colourful view of the bright star cluster NGC 3532. Some of the stars still shine with a hot bluish colour, but many of the more massive ones have become red giants and glow with a rich orange hue. NGC […]

Islamabad: The emergence of life is a mystery. Nevertheless, researchers agree that water is a precondition for life. The first cell emerged in water and then evolved to form multicellular organism. The oldest known single-cell organism on Earth is about 3.5 billion years old. So far, so good. But if life emerged in water, where […]

Islamabad: In a genome comparison conducted by a working group led by molecular biologist Leopold Eckhart of the University Department of Dermatology at MedUni Vienna, it was discovered that genes for important skin proteins arose in a common ancestor shared by humans and turtles 310 million years ago. The study has now been published in […]
