Deep learning: A new engine for ecological resource research
Deep learning is driven by big data, which brings new opportunities for target classification, detection, semantic segmentation, instance segmentation, and regression in ecological resource research. However, there are still great challenges in the standardization and sharing of data, the universality and interpretability of algorithms, and the enrichment and intelligence of applications. A recent study clarified the aforementioned frontier issues, which was published in the 'Science China Terrae' journal. (2020-05-21)

Hungry galaxies grow fat on the flesh of their neighbours
Galaxies grow large by eating their smaller neighbours, new research reveals. Exactly how massive galaxies attain their size is poorly understood, not least because they swell over billions of years. But now a combination of observation and modelling from researchers led by Dr Anshu Gupta from Australia's ARC Centre of Excellence for All Sky Astrophysics in 3 Dimensions (ASTRO 3D) has provided a vital clue. (2020-04-22)

T2K insight into the origin of the universe
Lancaster physicists working on the T2K major international experiment in Japan are closing in on the mystery of why there is so much matter in the universe, and so little antimatter. The Big Bang should have created equal amounts of matter and antimatter in the early universe. One of the greatest challenges in physics is to determine what happened to the antimatter, or why we see an asymmetry between matter and antimatter. (2020-04-15)

Why didn't the universe annihilate itself? Neutrinos may hold the answer

SHAPEIT4: An algorithm for large-scale genomic analysis
The examination of Haplotypes makes it possible to understand the heritability of certain complex traits. However, genome analysis of family members is usually necessary, a tedious and expensive process. Researchers (UNIGE/ UNIL/SIB) have developed SHAPEIT4, a powerful computer algorithm that allows the haplotypes of hundreds of thousands of unrelated individuals to be identified very quickly. Results are as detailed as when family analysis is per¬formed. Their tool is available online under an open source license. (2019-12-20)

Carbon cocoons surround growing galaxies far beyond previous beliefs
Researchers have discovered gigantic clouds of gaseous carbon spanning more than a radius of 30,000 light-years around young galaxies using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile. This is the first confirmation that carbon atoms produced inside of stars in the early Universe have spread beyond galaxies. No theoretical studies have predicted such huge carbon cocoons around growing galaxies, which raises questions about our current understanding of cosmic evolution. (2019-12-17)

Cannabis reduces headache and migraine pain by nearly half
Inhaled cannabis reduces self-reported headache severity by 47.3% and migraine severity by 49.6%, according to a recent study by Washington State University researchers published in the Journal of Pain. The study also found no evidence that cannabis caused 'overuse headache,' a pitfall of more conventional treatments. The researchers did see patients using larger doses of cannabis over time, indicating they may be developing tolerance to the drug. (2019-11-25)

Not all hypertension drugs are created equal, reports big-data study
For those with extremely high blood pressure, or hypertension, there are many initial medication options -- so many that it can be hard to know which one to use. Now, a Yale-coauthored paper in Lancet provides more information about the relative safety and effectiveness of different hypertension drugs in order to inform this critical treatment decision. The study reveals that angiotensin converting enzyme (ACE) inhibitors may not be the best choice for initial treatment. (2019-10-25)
