During the Space Race, scientists in both the United States and the Soviet Union investigated the concept of ion propulsion. Like many early Space Age proposals, the concept was originally explored by luminaries like Konstantin Tsiolkovsky and Hermann Oberth – two of the “forefathers of rocketry.” Since then, the technology has been validated repeatedly by …

The Milky Way has a missing pulsar problem in its core. Astronomers have tried to explain this for years. One of the more interesting ideas comes from a team of astronomers in Europe and invokes dark matter, neutron stars, and primordial black holes (PBHs). Astronomer Roberto Caiozzo, of the International School for Advanced Studies in …

Small but mighty, lysosomes play a surprisingly important role in cells despite their diminutive size. Making up only 1-3% of the cell by volume, these small sacs are the cell鈥檚 recycling centers, home to enzymes that break dow [url=https://www.nike-dunk.es]dunk nike high[/url] n unneeded molecules into small pieces that can then be reassembled to form new ones.

Here is a simple calculation.The electricity regulator, National Electric Power Regulatory Authority (Nepra), has determined an average electricity tariff of Rs10.49/Kwh for the last fiscal year. To make consumers pay extra, the federal government has levied a few surcharges. F [url=https://www.valela.at]ugg mini[/url] irst, there is a debt servicing surcharge which is Rs0.43/Kwh. Then, there is a tarif [url=https://www.adidassamba.com.de]adidas samba og[/url] f rationalisation surcharge of Rs0.96/Kwh and a Neelum-Jhelum surcharge of Rs0.10/Kwh. Combine these surcharges and they become a total of Rs1.49/Kwh. Consumers then pay an additional sales [url=https://www.stanley-cup.us]stanley store[/url] tax on these surcharges at 17%, which is an extra Rs0.25/Kwh. All in all, consumers pay over and above Rs1.74/Kwh in surcharges alone, which is equivalent to 17% more of what Nepra has determined as the price of electricity. With roughly 74 billion units of electricity sold every year in Pakistan, the federal government generates more than Rs129 billion through levying of surcharges alon

Space travel and exploration was never going to be easy. Failures are sadly all too common but it’s wonderful to see missions exceed expectations. The Japanese Space Agency’s SLIM lunar lander was only supposed to survive a single day but it’s survived three brutal, harsh lunar nights and is still going. The temperatures plummet to …

It’s difficult to actually visualise a universe that is changing. Things tend to happen at snails pace albeit with the odd exception. Take the formation of galaxies growing in the early universe. Their immense gravitational field would suck in dust and gas from the local vicinity creating vast collections of stars. In the very centre …

We are all very familiar with the concept of the Earth’s magnetic field. It turns out that most objects in space have magnetic fields but it’s quite tricky to measure them. Astronomers have developed an ingenious way to measure the magnetic field of the Milky Way using polarised light from interstellar dust grains that align …
