Tähtienvälistä pölyä ja vuosittaisia supernovaräjähdyksiä
Suurimman osan ajasta tähdet ovat tasapainossa tähden omaan energiantuotantoon perustuvan paineen ulospäin työntämän voiman ja tähden oman massan sisäänpäin vetävän painovoiman välillä. Tähtien energiantuotannon lähde on ydinfuusio, jossa kevyemmät alkuaineet muuttuvat raskaammiksi, kuten vety heliumiksi, vapauttaen energiaa tähden ytimessä. Massiivisimmissa … Continue reading
Biomimicry: A fairway to seek sustainable solutions for a better world
Biomimicry is “Innovation Inspired from Nature.” It is nothing but learning from nature or taking design ideas from nature. It is a new way of inventing by looking at the natural world for inspiration. When I was in school and … Continue reading
Medicinal Chemistry: an essential field in dire need of dedicated experts

Embracing the New Year in the Midst of Seasonal Darkness

Lignin – the new petroleum?
The world has been heavily dependent on fossil geo-resources for its scientific exploration and material progress, so far. Due to fast depletion, non-renewability, and increased carbon foot prints of fossil geo-resources, there is a need for technological maneuvers to combat … Continue reading

NOT, ketterä teleskooppi, kirjoittajana Erkki Kankare
Covid-19 pandemian aikana sosiaalisten lähikontaktien vähentäminen on tärkeää koronaviruksen leviämisen ehkäisemiseksi.

Tutkijoille koronavirukseen liittyvät rajoitukset vaikuttavat tutkimusaineiston hankintaan … Continue reading
