A researcher at the UPV/EHU-University of the Basque Country proposes analysing characteristics such as the location and visibility of Palaeolithic works to try to deduce their purpose Blanca Ochoa, a researcher in the UPV/EHU’s department of Geography, Prehistory and Archaeology, proposes analysing the spaces in which the artistic figures of the Palaeolithic are represented to try and deduce the purpose of these expressions. In her study she observed chronological differences in the location of the drawings and engravings, which could indicate that the function and meaning of cave art gradually changed throughout the Upper Palaeolithic.

Malaria is one of the world’s most serious infectious diseases and affects more than 200 million people each year. Scientists at the University of Oslo have examined the bark from two African trees and found substances that can kill both the mosquitoes that transmit malaria, and the parasite itself.

Researchers have discovered minerals from 43 meteorites that landed on Earth 470 million years ago. More than half of the mineral grains are from meteorites completely unknown or very rare in today’s meteorite flow. These findings mean that we will probably need to revise our current understanding of the history and development of the solar system.

A Hokkaido University researcher has successfully developed a method to accurately manipulate gene expression by light illumination and demonstrated its usability by creating double-headed zebrafish.

It has been difficult to freely manipulate the timing and duration of gene expression using existing gene manipulation technologies, which depend on organism’s gene regulating mechanism. In recent years, methods using light to regulate gene expression have been developed, but deemed insufficient to manipulate embryonic development. This is due to a time lag of several hours that occurs from light irradiation to the start/cessation of protein production. Existing photocontrol technologies also require genetic modification, a process that is not only time-consuming but also strictly regulated by the Cartagena Protocol.

More than 100 billion micrometeorites (MMs) fall to Earth each year. Until now, scientists believed that these particles could only be found in the cleanest environments, such as the Antarctic. In their new paper for Geology, M.J. Genge and colleagues show that, contrary to that expectation, micrometeorites can be recovered from city rooftops (for this example, primarily in Norway) and that, unlike those from the Antarctic, they are the youngest collected to date.

Assessing the Potential of Insects as Food and Feed in assuring Food Security 23-25 January, FAO, Rome
Mark Smulders, Senior Economist Agricultural Development Economics Division FAO - Rome

What is food security?
•Food security as a development objective
•Food security and nutrition – underlying concepts
•Consultation themes and “assuring food security”
