Starvation Induces Vacuolar Targeting and Degradation of the Tryptophan Permease in Yeast
In Saccharomyces cerevisiae, amino acid permeases are divided into two classes. One class, represented by the general amino acid permease GAP1, contains permeases regulated in response to theExpand

The Yeast Phosphatidylinositol Kinase Homolog TOR2 Activates RHO1 and RHO2 via the Exchange Factor ROM2
The Saccharomyces cerevisiae phosphatidylinositol kinase homolog TOR2 is required for organization of the actin cytoskeleton. Overexpression of RHO1 or RHO2, encoding Rho-like GTPases, or ROM2,Expand

Carbon isotopic composition of soil CO2 efflux, a powerful method to discriminate different sources feeding soil CO2 degassing in volcanic-hydrothermal areas
Abstract A new method combining measurements of soil CO 2 flux and determinations of the carbon isotopic composition of soil CO 2 efflux was developed in order to qualitatively and quantitativelyExpand

The RHO1‐GAPs SAC7, BEM2 and BAG7 control distinct RHO1 functions in Saccharomyces cerevisiae
In Saccharomyces cerevisiae, the small GTPase RHO1 plays an essential role in the control of cell wall synthesis and organization of the actin cytoskeleton. Several regulators for RHO1 are known,Expand

Excess mortality in Europe following a future Laki-style Icelandic eruption
Historical records show that the A.D. 1783–1784 Laki eruption in Iceland caused severe environmental stress and posed a health hazard far beyond the borders of Iceland. Given the reasonableExpand

Impact of future Arctic shipping on high‐latitude black carbon deposition
[1] The retreat of Arctic sea ice has led to renewed calls to exploit Arctic shipping routes. The diversion of ship traffic through the Arctic will shorten shipping routes and possibly reduce globalExpand

Global volcanic aerosol properties derived from emissions, 1990-2014, using CESM1(WACCM)
Accurate representation of global stratospheric aerosols from volcanic and non-volcanic sulfur emissions is key to understanding the cooling effects and ozone-losses that may be linked to volcanicExpand

Climatic impact of the long‐lasting 1783 Laki eruption: Inapplicability of mass‐independent sulfur isotopic composition measurements
[1] The long-lasting 1783–1784 CE Laki flood lava eruption in Iceland released around 120 Tg of sulfur dioxide into the upper troposphere/lower stratosphere. Northern Hemisphere temperature proxyExpand

Importance of tropospheric volcanic aerosol for indirect radiative forcing of climate
Observations and models have shown that continuously degassing volcanoes have a potentially large effect on the natural background aerosol loading and the radiative state of the atmosphere. We use aExpand

Glucocorticoids promote breast cancer metastasis
Diversity within or between tumours and metastases (known as intra-patient tumour heterogeneity) that develops during disease progression is a serious hurdle for therapy1–3. Metastasis is the fatalExpand
