    The idea of terraforming Mars – aka “Earth’s Twin” – is a fascinating idea. Between melting the polar ice caps, slowly creating an atmosphere, and then engineering the environment to have foliage, rivers, and standing bodies of water, there’s enough there to inspire just about anyone! But just how long would such an endeavor take, what would it cost us, and is it really an effective use of our time and energy? Such were the questions dealt with by two papers presented at NASA’s “Planetary Science Vision 2050 Workshop”...

    Biodegradable Packages will keep your Food Fresh

    Active packaging extends food's shelf life

    Active packaging extends food’s shelf life

    KTU researchers are creating biodegradable food packaging materials, which, in addition, will also keep food fresh for longer. This innovation would solve 2 problems at once: assist in cutting down packaging waste and in reducing the number of food-borne illnesses. On average a European country citizen produces around 160 kilos of packaging waste; ~19% of which is plastic. “Food packaging is mainly made from various plastics, which are being produced from non-renewable sources and are non-biodegradable. Also, it is not always possible to recycle them as leftovers from food amount to almost 50% of the packaging waste,” says Paulius Pavelas Danilovas, KTU.

    Headed by Danilovas, the team of researchers at the KTU Department of Polymer Chemistry and ...

    Flashy 1st images arrive from NOAA’s GOES-16 Lightning Mapper

    March 7, 2017, Categories  Astronomy/Space, Environment/Geology

    This is one hour of GOES-16's Geostationary Lightning Mapper (GLM) lightning data from Feb. 14.

    This is one hour of GOES-16’s Geostationary Lightning Mapper (GLM) lightning data from Feb. 14, when GLM acquired 1.8 million images of the Earth. It is displayed over GOES-16 ABI full disk Band 2 imagery. Brighter colors indicate more lightning energy was recorded; color bar units are the calculated kilowatt-hours of total optical emissions from lightning. The brightest storm system is located over the Gulf Coast of Texas, the same storm system in the accompanying video. This is preliminary, non-operational data. Credits: NOAA/NASA

    Detecting and predicting lightning just got a lot easier...

    Lake Towuti, Indonesia. (A) Regional context for Lake Towuti on the island of Sulawesi in Indonesia. Red box indicates approximate location of part B. Background is the Ocean base map from ESRI et al. (2015). (B) Generalized geologic map of Lake Towuti and the surrounding area showing the dominance of ultramafic material. Map is modified from Costa et al. (2015). (C) Bathymetry of Lake Towuti showing the location of the two analyzed sediment cores at the distal margins of the Mahalona River delta (white dots labeled 4 for TOW4 and 5 for TOW5). River inputs are shown in thin blue lines, with the Mahalona River shown as a thick blue line. Credit: Goudge et al. and GSA Bulletin
