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 […]

Read MoreIslamabad: Certain primordial stars – those between 55,000 and 56,000 times the mass of our Sun, or solar masses — may have died unusually. In death, these objects – among the Universe’s first-generation of stars — would have exploded as supernovae and burned completely, leaving no remnant black hole behind. Astrophysicists at the University of […]

Read MoreIslamabad: For decades scientists have believed that galaxy mergers usually result in the formation of elliptical galaxies. Now, for the first time, researchers using ALMA and a host of other radio telescopes have found direct evidence that merging galaxies can instead form disc galaxies, and that this outcome is in fact quite common. This surprising […]

Read MoreIslamabad: Humanity is on the threshold of being able to detect signs of alien life on other worlds. By studying exoplanet atmospheres, we can look for gases like oxygen and methane that only coexist if replenished by life. But those gases come from simple life forms like microbes. What about advanced civilizations? Would they leave […]

Mammals communicate socially through visual, auditory, and chemical signals. The chemical sense is in fact the oldest sense, shared by […]
Read MoreDefining what makes a star “Sun-like” is as difficult as defining what makes a planet “Earth-like.” A solar twin should have a temperature, mass, and spectral type similar to our Sun. We also would expect it to be about 4.5 billion years old. However, it is notoriously difficult to measure a star’s age so astronomers […]
Read MoreThe Earth’s magnetic field flips, every few hundred thousand years or so on average, which means magnetic north becomes magnetic south and vice versa (the planet doesn’t actually turn upside down). New research suggests this change of direction can happen up to 10 times faster than previously thought. That’s big news for scientists studying how […]
