New Dartmouth smartphone app reveals users' mental health, performance, behavior
Dartmouth researchers and their colleagues have built the first smartphone app that automatically reveals college students' mental health, academic performance and behavioral trends. In other words, your smartphone knows your state of mind -- even if you don't -- and how that affects you. The StudentLife app, which compares students' happiness, stress, depression and loneliness to their academic performance, also may be used in the general population -- for example, to monitor mental health, trigger intervention and improve productivity in workplace employees.

Pupil size shows reliability of decisions
The precision with which people make decisions can be predicted by measuring pupil size before they are presented with any information about the decision, according to a new study published in PLOS Computational Biology this week.

World population to keep growing this century, hit 11 billion by 2100
The chance that world population in 2100 will be between 9.6 billion and 12.3 billion people is 80 percent, according to the first such United Nations forecast to incorporate modern statistical tools.

Ebola outbreak 'out of all proportion' and severity cannot be predicted
A mathematical model that replicates Ebola outbreaks can no longer be used to ascertain the eventual scale of the current epidemic, finds research conducted by the University of Warwick. Dr. Thomas House, of the University's Warwick Mathematics Institute, developed a model that incorporated data from past outbreaks that successfully replicated their eventual scale.

The science behind swimming

Nature: New drug blocks gene driving cancer growth
When active, the protein called Ral can drive tumor growth and metastasis in several human cancers including pancreatic, prostate, lung, colon and bladder. Unfortunately, drugs that block its activity are not available. A study published today in the journal Nature uses a novel approach to target the activation of these Ral proteins.

Decoding 'sweet codes' that determine protein fates
The research group lead by Professor Koichi Kato of the Institute for Molecular Science, National Institutes of Natural Sciences developed a methodology for quantitatively describing the dynamic behaviors of complicated sugar chains in solution at atomic resolution by combining a sophisticated NMR spectroscopic approach with an ingenious molecular dynamics simulation technique. This study has just been published in Angewandte Chemie International Edition (published online on Sept.4, 2014).

Getting hot and wet in Vermont
A fundamental challenge of climate change forecasting is how to bridge the gap between global-scale models and local impacts. A new study -- the first-of-its kind for the Lake Champlain region -- bridges this gap and forecasts that northern Vermont and southern Quebec by 2100 will get eight degrees Fahrenheit hotter; Burlington, Vt., will experience 10 more days in July above 90; and ski resorts will see 50 percent less snowfall.

National Renewable Energy Laboratory updates cetane data used for development of energy efficient fuels and engines
The Energy Department's National Renewable Energy Laboratory has released a long-anticipated update to the source-of-record for cetane number data. This information is vital to the development of new, energy-efficient, low-carbon fuels and compatible engines. Researchers, as well as members of the engine, vehicle, and fuel industries, rely on these numbers to target compounds for development of new fuels capable of greater energy efficiency, cleaner emissions, and maximum performance in diesel engines.

Nano-pea pod model widens electronics applications
Periodic chain-like nanostructures are widely used in nanoelectronics. Typically, chain elements include the likes of quantum rings, quantum dots, or quantum graphs. Such a structure enables electrons to move along the chain, in theory, indefinitely. Now, a new study, published in EPJ B, identifies ways of disturbing the periodicity of a model nanostructure to obtain the desired discrete energy spectrum with localized electrons.

Most accurate measures of gene expression
RNA-sequencing data analysis method BitSeq developed by Academy Research Fellow Antti Honkela's, Univeristy of Helsinki, research group and University of Manchester researchers has been found to be the most accurate gene transcript expression estimation method in a large international assessment. The method is based on probabilistic modelling which can capture the uncertainty related to the measurements.
