ALMA captures distant colliding galaxy dying out as it loses the ability to form stars

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.

Discovery boosts theory that life on Earth arose from RNA-DNA mix

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 […]

The upside of volatile space weather

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 […]

About half of Sun-like stars could host rocky, potentially habitable planets

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 […]

Where were Jupiter and Saturn born?

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.

Turtles and dinosaurs: Scientists solve reptile mysteries with landmark study on the evolution of turtles

A team of scientists, including researchers from the California Academy of Sciences, has reconstructed a detailed “tree of life” for turtles. The specifics of how turtles are related — to one another, to other reptiles, and even to dinosaurs — have been hotly debated for decades. Next generation sequencing technologies in Academy labs have generated […]

Research identifies ‘volume control’ in the brain that supports learning and memory

A “molecular volume knob” regulating electrical signals in the brain helps with learning and memory, according to a Dartmouth study.The molecular system controls the width of electrical signals that flow across synapses between neurons. The finding of the control mechanism, and the identification of the molecule that regulates it, could help researchers in their search […]

Lung-on-chip provides new insight on body’s response to early tuberculosis infection

Scientists have developed a lung-on-chip model to study how the body responds to early tuberculosis (TB) infection, according to findings published today in eLife. TB is a disease caused by the bacterium Mycobacterium tuberculosis (M. tuberculosis) and most often affects the lungs. The model reveals that respiratory system cells, called alveolar epithelial cells, play an […]

NTC countering massive cyber-attacks daily: Viqar Rashid Khan

Islamabad: Managing Director National Telecommunication Corporation (NTC) Viqar Rashid Khan has said that around 0.8 million attempts of cyber-attacks on internet consumers are successfully countered every day in Pakistan. In an interview, he said NTC successfully countered 250 million cyber-attacks mainly from Israel and India.“Due to deadly virus, it is dangerous and difficult to hold […]

How water fled the red planet

Islamabad: Mars once had oceans but is now bone-dry, leaving many to wonder how the water was lost. University of Arizona researchers have discovered a surprisingly large amount of water in the upper atmosphere of Mars, where it is rapidly destroyed, explaining part of this Martian mystery. Shane Stone, a graduate student in the UArizona […]

18 reserve astronauts selected for China’s manned space program

Beijing: China’s manned space program has entered the mission preparation stage with the selection of a new group of 18 reserve astronauts. According to the China Manned Space Agency (CMSA), the reserve astronauts, including one female, have been selected recently from 2,500 candidates. Among them are seven spacecraft pilots, seven space flight engineers and four […]

Parallel universes really exist

Islamabad: Griffith University academics are challenging the foundations of quantum science with a radical new theory based on the existence of, and interactions between, parallel universes. In a paper published in the journal Physical Review X, Professor Howard Wiseman and Dr Michael Hall from Griffith’s Centre for Quantum Dynamics, and Dr Dirk-Andre Deckert from the […]
