The good news for Volkswagen is that it delivered almost 7.5 million vehicles to customers during the first three quarters of 2015. The bad news is that 8.5 million of VW’s cars will most likely be subject to a mandatory recall — and that’s just in Europe.

The fallout from the Volkswagen emissions scandal continues to reverberate, four weeks after revelations about the installation of “defeat device” software in diesel-powered cars slammed the newswires. Now, the world’s largest automaker is facing a global public relations crisis. This includes its home base: 2.8 million of the recalled vehicles were sold in Germany.

Un nuevo estudio ha encontrado que los vientos fuertes están removiendo grandes cantidades de nieve de la Antártida, lo que podría aumentar las estimaciones de lo que el continente podría contribuir a elevar el nivel del mar. Hasta ahora, los científicos habían pensado que la mayor parte de la nieve arrastrada por el viento era simplemente depositada en otras partes de la misma superficie. Sin embargo, el nuevo estudio muestra que en ciertas partes, llamadas zonas de socavación, casi el 90 %, aproximadamente 80 mil millones de toneladas por año son eliminadas en lugar de ser vaporizadas. El hallazgo significa que los científicos deben ajustar sus modelos de cuánta masa está perdiendo la Antártida, y lo mucho que puede perder en el futuro. El estudio aparece esta semana en la revista Geophysical Research Letters.

Los científicos han predicho que la aparición de crecimiento de las plantas de primavera se desplazará por una mediana de tres semanas antes, durante el próximo siglo, como resultado del aumento de las temperaturas globales.

New research by Dana-Farber Cancer Institute scientists raises the prospect of cancer therapy that works by converting a tumor's best friends in the immune system into its gravest enemies.

In a study published in the journal Science, an international collaboration of investigators from Dana-Farber, Harvard Medical School, Boston Children's Hospital, and the University of Strasbourg uncovered a mechanism that allows key immune system cells to keep a steady rein on their more belligerent brother cells, thereby protecting normal, healthy tissue from assault. The discovery has powerful implications for cancer immunotherapy researchers say: by blocking the mechanism with a drug, it may be possible to turn the attack-suppressing cells into tumor-attacking cells.

A global ocean lies beneath the icy crust of Saturn's geologically active moon Enceladus, according to new research using data from NASA's Cassini mission. 

Researchers found the magnitude of the moon's very slight wobble, as it orbits Saturn, can only be accounted for if its outer ice shell is not frozen solid to its interior, meaning a global ocean must be present. 

The finding implies the fine spray of water vapor, icy particles and simple organic molecules Cassini has observed coming from fractures near the moon's south pole is being fed by this vast liquid water reservoir. The research is presented in a paper published online this week in the journal Icarus.
