Direct exoplanet investigation using interstellar space probes

, 2017
Experience in exploring our own solar system has shown that direct investigation of planetary bodies using space probes invariably yields scientific knowledge not otherwise obtainable.

Probing the structure of space-time with cosmic rays [PDF]

Physical Review D, 2000
We discuss on general grounds the possibility of testing specia relativity and the underlying small scale structure of space-time by studying the interactions of Cosmic Rays (CR) with universal diffuse background radiation.The interactions we consider are the ones characterized by well defined energy thresholds whose energy position can be predicted on

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

A Demonstration of Interstellar Navigation Using New Horizons

The Astronomical Journal
As NASA’s New Horizons spacecraft exits the solar system bound for interstellar space, it has traveled so far that the nearest stars have shifted markedly from their positions seen from Earth. We demonstrated this by imaging the Proxima Centauri and Wolf

Prediction of Dynamic Plasmapause Location Using a Neural Network

Space Weather, 2021
As a common boundary layer that distinctly separates the regions of high‐density plasmasphere and low‐density plasmatrough, the plasmapause is essential to comprehend the dynamics and variability of the inner magnetosphere.

Probing Protein Fold Space with a Simplified Model [PDF]

Journal of Molecular Biology, 2008
We probe the stability and near-native energy landscape of protein fold space using powerful conformational sampling methods together with simple reduced models and statistical potentials. Fold space is represented by a set of 280 protein domains spanning all topological classes and having a wide range of lengths (33-300 residues) amino acid ...

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Instrumenting the city: developing methods for observing and understanding the digital cityscape [PDF]

, 2006
We approach the design of ubiquitous computing systems in the urban environment as integral to urban design. To understand the city as a system encompassing physical and digital forms and their relationships with people’s behaviours, we are developing ...

Probing chemical space with alkaloid-inspired libraries [PDF]

Nature Chemistry, 2014
Screening of small-molecule libraries is an important aspect of probe and drug discovery science. Numerous authors have suggested that bioactive natural products are attractive starting points for such libraries because of their structural complexity and sp 3 -rich character.
