Light helps develop programmable materials
Phys.org - latest science and technology news stories - Hace 4 horas
Light of a certain wavelength can be used to put so-called active materials into motion and control their movement. In the future, this discovery can become significant in widely different areas such as environmental protection, medicine and the development of new materials which can be programmed.

Carta a la UE d’una refugiada siriana
Ara.cat - Portada - Hace 4 horas
Quan vam arribar teníem diners per comprar una mica de menjar. Ara ja se’ns han acabat. Fem hores de cua per un entrepà. Fa poc el meu marit li va dir a un periodista: “La gent n’està tipa. Potser demà tiraran a terra les portes i una riuada de gent traspassarà la frontera”. El periodista li va contestar: “Quantes armes teniu?” Si sabéssim portar armes o volguéssim portar-ne no hauríem fugit de Síria.

Ara.cat - Portada - Hace 4 horas
Potser és que alguna cosa fa pudor de podrit als nostres dies o potser és que el món és massa estret per al nostre esperit, però 'Hamlet' continua tan vigent com al segle XVII i segueix atraient artistes i públic al seu regne teatral. Sales de Madrid, Sevilla i Barcelona -la versió que es pot veure al Teatre Lliure va exhaurir entrades abans de començar- han tornat a un text tan conegut com inabastable per commemorar els 400 anys de la mort de Shakespeare.

El ministre de Justícia, Rafael Catalá, ha assegurat aquest divendres a la tarda en declaracions a Europa Press que Podem és un partit "proper al moviment terrorista etarra" i a l'independentisme català. "Es manifesten com a propers a aquests sentiments", ha recalcat Catalá abans de tancar un acte a la facultat de Dret de la Universitat Nacional d'Educació a Distància (UNED).
Colonise Mars as humanity’s plan B? It’s a dangerous fantasy
New Scientist - Home - Hace 5 horas
Scott Kelly's year in space rekindles hope of Mars as humanity's bolthole. Such ambitions are misguided, say Stephen Cave, Lucianne Walkowicx and Huw Price

Engineered monomeric streptavidin
Latest Science News -- ScienceDaily - Hace 5 horas
A novel streptavidin variant with improved biotin binding characteristics allows stable monovalent detection of biotinylated targets for imaging applications and can be recombinantly fused to introduce a biotin binding tag, report researchers.
Discovery of cellular counting mechanism used for size control in algae with links to cancer genetics
Latest Science News -- ScienceDaily - Hace 5 horas
Cell size is a critical trait for improved yields of algal biofuels, scientists have discovered. Unlike the textbook paradigm of cell proliferation where cells double in size and then immediately split into two new daughters, cells of Chlamydomonas and many of its green algal relatives can enlarge more than ten times in size before they start dividing.
New cause of exceptional Greenland melt revealed
Latest Science News -- ScienceDaily - Hace 5 horas
The energy associated with air temperature and moisture content, rather than radiant energy from the sun, was responsible for more melt during the 2012 exceptional melt episodes on the Greenland Ice Sheet, new research indicates. Using the PROMICE automatic weather station data, they found climate models underestimate the impact of exceptionally warm weather episodes on the ice sheet.
Researcher synthesizes hybrid molecule that delivers a blow to malignant cells
Latest Science News -- ScienceDaily - Hace 5 horas
A new molecule recently developed shows promise for treating breast cancer. The protein/polymer-gold nanoparticle composite, besides being easy to synthesize, can load up with drugs, carry them to malignant cells, and unload them where they can do the most damage with the least amount of harm to the patient.
