Study shows role of depression in the ongoing tobacco epidemic

A study by Columbia University's Mailman School of Public Health found that depression significantly increased in the US from 2005 to 2013 among current, former, and never smokers. The prevalence of depression is consistently higher among smokers, but the rate of increase was more prominent among former and never smokers.

Inactivity, excess weight linked to hard-to-treat heart failures

Research from UT Southwestern Medical Center found that inactivity and excess weight are strongly associated with heart failure with preserved ejection fraction, which has a poor five-year survival rate of around 30-40%. Increasing physical activity levels and reducing weight may be crucial for combating this growing disease.

Modern housing associated with reduced malaria risk in sub-Saharan Africa

A study published in PLOS Medicine found that modern houses with metal roofs and finished walls are associated with a reduced risk of malaria in children under age 5. The researchers analyzed data from 29 surveys in 21 African countries and found a significant correlation between improved housing conditions and lower malaria rates.

Cars and chlamydia killing Queensland koalas

A University of Queensland-led study found that cars and chlamydia were the top causes of a 80% decline in south-east Queensland koalas over two decades. At least a quarter of healthy, breeding koalas died from car accidents, while half the population was affected by multiple diseases or health problems.

A better way to swallow

A Pittsburgh engineer has received a $549,139 NSF CAREER Award to create a new screening method for swallowing disorders. The technology uses high-resolution vibration and sound recordings to diagnose dysphagia, allowing doctors to identify silent aspirators more accurately.

UTHealth study outlines framework for identifying disease risk in genome sequence

Researchers at UTHealth have developed a framework to analyze genome sequences and identify genetic variations that raise or lower disease risk. The study used genomic data from over 3,000 individuals and identified genes related to blood lipid levels, white blood cell count, and heart attack diagnosis.

Astrophotography as a gateway to science

UC Riverside scientists created astrophotography classes for non-science students, resulting in improved understanding of telescopes and cameras, as well as renewed interest in astronomy. The cost-effective courses also encouraged students to take up astrophotography as a hobby, opening the path to future amateur astronomers.

Analysis examines characteristics of users of online infidelity matchmaking

Researchers studied data from Ashley Madison to identify key characteristics of its users. Income proved to be a significant factor, indicating the service behaves like a luxury good. Religiosity also showed a notable correlation with user spending rates, decreasing by 18% for every additional religious congregation per 1,000 people.

Report proposes standards for sharing data and code used in computational studies

A new report by University of Illinois professors recommends standardizing sharing of data sets and software code to improve reproducibility in computational research. The recommendations include documenting digital objects, making datasets and workflows accessible, and implementing reproducibility checks before publication.

What to do with the data?

Researchers are preparing to tackle an onslaught of petabytes of complex data from sophisticated experiments, including CERN's Large Hadron Collider. To keep up with the challenge, experts propose developing exascale supercomputers and smarter networks, as well as reengineering software to adapt to future hardware developments.

Report reassesses variations in global warming

Experts reassess temperature trends, finding that global warming slowed less from 1998 to 2012, peaking in 2016 at a level around 1.5ºC above its level early in the Industrial Revolution. Global temperatures remain high due to exceptionally low sea-ice extent in both hemispheres.
