Arctic Space Centre in Finland provides answers to hot arctic
questions - Finnish Meteorological Institute - 03 April 2017
What does the Arctic region's snow cover look like today? How
thick was the ice that covered the Arctic Ocean in January?
Will we see the Aurora Borealis in the near future? The Finnish
Meteorological Institute's Arctic Space Centre will provide
answers to all these questions and many others.
April’s Hits Parade - Top 5
Our most read news releases in April 2017
1.No democracy without women’s rights release from
University of Gothenburg - 11 April 2017
Why did the Arab spring fail? Despite a number of revolutions
in the Arab world, in the end only Tunisia emerged as a
functioning democracy. Results from an interdisciplinary
research project at the University of Gothenburg indicate that
the problem might be traced partially to the lack of women’s
civil rights in the region.
2. Radboud university medical center connects first click-on arm
prosthesis to nerves - Radboud University Nijmegen Medical
Centre - 25 April 2017
The first patient in the Netherlands received his click-on robotic
arm. By means of a new technique, this robotic arm is clicked
directly onto the bone. A unique characteristic of this prosthesis
is that it can be controlled by the patient's own thoughts.
Worldwide, there are only a handful of patients with such a
prosthesis.
3. How do you eat your chocolate bunny? Vast majority prefer to
start with the ears - Wiley - 04 April 2017
New research carried out online has found that 59% of 28,113
respondents preferred to eat chocolate rabbits starting with the
ears, 33% indicated that they had no starting point preference,
and 4% indicated that they started with the tail or feet.
4. Solar cell design with over 50% energy-conversion efficiency Kobe University - 25 April 2017
Solar cells convert the sun’s energy into electricity by converting
photons into electrons. A new solar cell design could raise the
energy conversion efficiency to over 50% by absorbing the
spectral components of longer wavelengths that are usually lost
during transmission through the cell. These findings were
published on April 6 in the online edition of Nature
Communications.
5. Scientists develop a novel electronic system that detects a
driver’s symptoms of fatigue and prevents traffic accidents University of Granada- 18 April 2017
Researchers from the University of Granada (UGR) and the
Polytechnic University of Valencia (UPV) have designed a new
low-cost system that detects the drivers’ symptoms of fatigue and
distraction and helps preventing possible traffic accidents. The
system comprehends four sensors (body temperature, hand
pressure at the wheel, a light sensor in the headset, and a
collision and sudden braking detector), as well as a buzzer that
emits an acoustic signal when it detects symptoms of fatigue.

Le gisement de la Noira à Brinay (Cher): le site Acheuléen le plus
ancien du Nord-Ouest de l’Europe - 06 April 2017 - CENIEH
Une équipe scientifique française du Département de Préhistoire
du Muséum national d’Histoire naturelle, menée par Jackie
Despriée, et dont est membre Davinia Moreno, geochronologue du
Centro Nacional de Investigación sobre la Evolución Humana
(CENIEH), vient de publier dans la revue Quaternaire deux articles
sur le gisement de la Noira. Ce site, localisé dans la vallée du
Cher, dans la région Centre-val de Loire en France, a livré des
preuves les plus anciennes de la présence de la culture
acheuléenne dans le Nord-Ouest de l’Europe.

Dionaea: Wie die Verdauung in Gang kommt - 20 April 2017 Julius-Maximilians-Universität Würzburg, JMU
Die Venusfliegenfalle (Dionaea muscipula) gehört zu den
Pflanzen, die sich von Tieren ernähren. Mit ihren Klappfallen
fängt sie Insekten, mit einem Verdauungssekret aus
Drüsenzellen löst sie ihre Beute auf und verleibt sich die
freigesetzten Nährstoffe ein.
Die Absonderung eines Verdauungssaftes aus Drüsen ist schon
seit Darwins Zeiten als Tatsache gesetzt. Doch gemessen und
analysiert wurde dieser Vorgang erst jetzt: Ein internationales
Forschungsteam unter Leitung des Biophysikers Rainer Hedrich
von der Universität Würzburg stellt die Ergebnisse im Journal
PNAS vor.
Venusfliegenfalle: Die Innenseite der Fallen ist mit roten
Drüsen bestückt (a), die nach dem Beutefang wie ein
pflanzlicher „Magen“ funktionieren. Dabei entlassen die
Drüsen ein Verdauungssekret. Diese Sekretion konnte erstmals
auf Vesikel-Ebene an Pflanzen gezeigt werden (b). Die
modellhafte Darstellung (c) zeigt, dass aktivierte Drüsen
Kalzium (Ca2+) aufnehmen, was die Jasmonat-Signalkette in
Gang setzt und zur Sekretion von Salzsäure (HCl) und
Verdauungsenzymen führt. (Bild: Sönke Scherzer/Dirk Becker)
Better quality relationships associated with reduced
dementia risk - 28 April 2017 - University of East Anglia
Positive social support from adult children is associated
with reduced risk of developing dementia, according to a
new research published today.Conversely, negative social
support is linked with increased risk, according to the 10year follow-up study carried out by a team of researchers
from the University of East Anglia (UEA), University College
London (UCL), London Metropolitan University and the
University of Nottingham.
La "memoria" ambiental se transmite hasta 14 generaciones
- 20 April 2017 -Centre for Genomic Regulation
El impacto en cambios ambientales se puede transmitir en
los genes de hasta 14 generaciones - el máximo tiempo
visto hasta ahora en animales- según un estudio del Centro
de Regulación Genómica (CRG) en Barcelona, del Instituto
de Investigación contra la Leucemia Josep Carreras y el
Instituto de Investigación Germans Trias y Pujol en el
campus Can Ruti de Badalona.Estos nuevos resultados,
publicados en la revista Science, son la muestra más
duradera de la preservación de un cambio ambiental en la
memoria a lo largo de generaciones nunca observada hasta
ahora.
