AI system can generate novel proteins that meet structural design targets（图）
AI系统 新型蛋白质 可调蛋白质
2023/6/6
MIT researchers are using artificial intelligence to design new proteins that go beyond those found in nature.
Asymmetry in CO2 emissions and removals could skew climate targets
carbon dioxide emissions climate targets carbon dioxide removals
2021/8/4
Changes in climate resulting from carbon dioxide (CO2) emissions into the Earth's atmosphere are not equal to the climate changes from deliberate CO2 removals -- and assuming such a balance could lead...
Survival Of The Least-Fit:Antiviral Drug Selectively Targets The Nastiest Viruses（图）
Survival Of The Least-Fit Antiviral Drug Selectively Nastiest Viruses
2017/11/24
An antiviral drug that inhibits a virus' replication machinery selectively targets the most-aggressive viruses, according to new research that looked at the infection of individual cells by a virus an...
Imagine if a dense thicket didn’t obstruct your path but instead picked you up and shuttled you through the forest. That’s what tightly packed DNA might be doing with important life molecules to get t...
Microbial protein targets: towards understanding and intervention
Microbial protein structure Biochemical analyses
2016/7/29
The symposium will bring together leading expertise in protein structure determination, biochemical characterisation and chemical biology to explore the most recent advances in the understanding
of p...
A comparison between rubble-pile and monolithic targets in impact simulations:Application to asteroid satellites and family size distributions
Asteroids Collisional physics Impact processes Satellites, General
2015/12/25
Collisions are a fundamental process in the creation of asteroid families and in satellite formation. For this reason, understanding the outcome of impacts is fundamental to the accurate modeling of t...
Genome-wide polymorphisms show unexpected targets of natural selection
population genomics natural selection
2015/12/11
Natural selection can act on all the expressed genes of an individual, leaving signatures of genetic differeniation or diversity at many loci across the genome. New power to assay these genome-wide ef...
Performance of a Practical Two-Step Detector for Non-Fluctuating Targets
Practical Two-Step Detector Non-Fluctuating Targets
2015/9/29
In this paper we analyze a two-step detection scheme for use in distributed sensor systems (e.g. statistical MIMO radar). The scheme arises when a data rate restriction forces each of the distributed ...
ASSESSMENT OF SENSOR CHARACTERISTICS OF AN AIRBORNE LASER SCANNER USING GEOMETRIC REFERENCE TARGETS
laser scanning accuracy high resolution point clouds sensor specifi cations
2015/8/13
In order to get an experimental insight on the characteristics of a modern airborne laser scanning system, we carry out
a set of experiments using geometrical targets on an air strip and use differen...
Identification of putative targets of Nkx2-5 in Xenopus laevis using cross-species annotation and microarray gene expression analysis
Microarray analysis Molecular Biology Development
2015/5/25
The heart is the first organ to form during development in vertebrates and Nkx2-5 is the first marker of cardiac specification. In Xenopus laevis, Nkx2-5 is essential for heart formation, but early ta...

The strategy is paying off. At the American Astronomical Society (AAS) meeting in Seattle this week, researchers reported early successes from the All-Sky Automated Survey for Supernova...
Genome-wide analysis for native thyroid hormone targets in developing brain and mechanisms of endocrine disruption at the thyroid hormone receptor
Thyroid hormone fetal brain development interference and signal brain development polychlorinated biphenyls (PCBS)
2014/12/11
Thyroid hormone (TH) plays an important role in fetal brain development. Therefore, exogenous factors that interfere with TH signaling may exert potentially important adverse effects on brain developm...
Nov. 18, 2014 – When a viral infection spread through five genetically identical mice in a row, the virus replicated faster and became more virulent or severe. But when the infection spread one-by-one...
PEBSI - A Monte Carlo simulator for bremsstrahlung arising from electrons colliding with thin solid-state targets
Monte Carlo simulation polarized electrons bremsstrahlung polarization target-thickness effects hard x-ray
2012/5/31
We present a Monte Carlo code dedicated to the simulation of bremsstrahlung arising in collisions of polarized electrons with thin target foils. The program consists of an electron transport algorithm...
