Reducing uncertainties in climate models
BJ Soden, WD Collins, DR Feldman - Science, 2018
Radiative forcing is a fundamental quantity for understanding both anthropogenic
and natural changes in climate. It measures the extent to which human activities
[such as the emission of carbon dioxide (CO 2), see the image] and natural events …





Transcriptome mapping in the 3D brain
S Mao - 2018
In eusocial insects, the vast majority of individuals sacrifice their reproductive
potential to support the reproductive queen. Although this system has evolved
repeatedly, there is still much debate surrounding its origin. Working with seven …




Phase separation and gene control
S Mao - 2018
In eusocial insects, the vast majority of individuals sacrifice their reproductive
potential to support the reproductive queen. Although this system has evolved
repeatedly, there is still much debate surrounding its origin. Working with seven …




Paul D. Boyer (1918–2018)
DS Eisenberg - Science, 2018
On 2 June, 2 months before his 100th birthday, Paul Boyer died peacefully,
surrounded by family, including Lyda, his wife of nearly 79 years. Paul was deeply
admired by his students, colleagues, and friends for his many talents. He was skilled …




Ghost dunes spotted on Mars
KT Smith - Science, 2018
Peutz–Jeghers Syndrome (PJS) causes benign polyps in the gut and a higher risk of
several cancers caused by mutations in the tumor suppressor gene STK11, which
encodes liver kinase B1 (LKB1). LKB1's role in this disease is thought to be related to …




Improved characterization of methane emissions from the US oil and gas supply chain
RA Alvarez, D Zavala-Araiza, DR Lyon, DT Allen… - 2018
The contribution of the US oil and natural gas supply chain to global methane
emissions–an important factor in climate warming–was estimated using ground-
based measurements and validated with region-wide aircraft measurements in areas …




Dynamic condensates activate transcription
AJ Plys, RE Kingston - Science, 2018
Every aspect of human function, from proper cell differentiation and development to
normal cellular maintenance, requires properly timed activation of the necessary
genes. This requires transcription of genomic DNA into messenger RNA (mRNA) …




A quantum future awaits
JM Taylor - 2018
A century ago, the quantum revolution quietly began to change our lives. A deeper
understanding of the behavior of matter and light at atomic and subatomic scales
sparked a new field of science that would vastly change the world's technology …




Nature's riverkeepers
S Boon - 2018
Researchers have calculated that between 15 million and 250 million beaver ponds
once covered North America. A booming 19th-century trade in beaver pelts, along
with a loss of habitat due to settlement, almost wiped them out. Beaver populations …




Neurotechnology to address big questions
T Knöpfel - Science, 2018
Emotions, cognition, and consciousness emerge with the processing of neuronal
information provided by memory readouts and senses. How this actually works
seemed for a long time to be a question too big to ask. Advances in neuroscience …

Liquid water on Mars
A Diez - Science, 2018
Without water, no form of life as we know it could exist. There is therefore great
interest in detecting liquid water on other planets of our Solar System. Landforms
such as dry river valleys and lakes show that liquid water must have been present on …




Hydrocarbon synthesis with vinyl cations
SH Kennedy, DA Klumpp - Science, 2018
Hydrocarbons—substances composed of carbon and hydrogen—are central to many
industrial processes, including fuel preparation, polymer manufacturing, and the
synthesis of feedstock chemicals (1). Many biosynthetic pathways also involve …

Colder Siberian winters in a warming world
K Hodges - 2018
In eusocial insects, the vast majority of individuals sacrifice their reproductive
potential to support the reproductive queen. Although this system has evolved
repeatedly, there is still much debate surrounding its origin. Working with seven …




[PDF] Response to Comment on “An excess of massive stars in the local 30 Doradus starburst”
FRN Schneider, H Sana, CJ Evans, JM Bestenlehner… - Science, 2018
Farr and Mandel reanalyze our data, finding initial mass function slopes for high-
mass stars in 30 Doradus that agree with our results. However, their reanalysis
appears to underpredict the observed number of massive stars. Their technique …




AAAS S&T Policy Forum explores US competitiveness, now and in the future
AQ Hoy - Science, 2018
The US scientific research and development enterprise stands at a critical juncture
that requires the convergence of basic research and commercial applications to
more quickly deliver benefits of nextgeneration technological innovation, said Arati …




Let your stars shine
V Sung - Science, 2018
A few months ago, one of my fellow graduate students was offered an incredible
career-building opportunity. His efforts on a student-led campaign to increase federal
funding for basic research had led to an invitation to speak on a conference panel …
