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.

This is a HSC-SSP image of a massive cluster of galaxies in the Virgo constellation showing numerous strong gravitational lenses. The distance to the central galaxy is 5.3 billion light years, while the lensed galaxies, apparent as the arcs around the cluster, are much more distant. This is a composite image in the g, r, and i band, and has a spatial resolution of about 0.6 arcseconds. Credit: NAOJ/HSC Project

The first massive data set of a “cosmic census” has been released using the largest digital camera on the Subaru Telescope. With its beautiful images now available for the public at large, figuring out the fate of the Universe has come one step closer. Data from the Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP) was released to the public on February 27th, 2017...

This beautiful Hubble image reveals a young super star cluster known as Westerlund 1, only 15,000 light-years away in our Milky Way neighborhood, yet home to one of the largest stars ever discovered. Stars are classified according to their spectral type, surface temperature, and luminosity. While studying and classifying the cluster’s constituent stars, astronomers discovered that Westerlund 1 is home to an enormous star.

Originally named Westerlund 1-26, this monster star is a red supergiant (although sometimes classified as a hypergiant) with a radius over 1,500 tim...

Middle-aged people who experience temporary blood pressure drops that often cause dizziness upon standing up may be at an increased risk of developing cognitive decline and dementia 20 years later, new Johns Hopkins Bloomberg School of Public Health research suggests. The findings suggest that these temporary episodes – orthostatic hypotension – may cause lasting damage, possibly because they reduce needed blood flow to the brain...
