The research, led by PhD candidate Adelle Goodwin from the Monash School of Physics and Astronomy will be featured at an upcoming American Astronomical Society meeting this week before it is published in Monthly Notices of the Royal Astronomical Society. Adelle leads a team of international researchers, including her supervisor, Monash University Associate Professor Duncan Galloway, and Dr David Russell from New York University Abu Dhabi.
Every species in nature is equipped with a strategy to survive in response to danger. Plants, too, have innate systems that are triggered in response to threats, such as insects feeding on them. For example, some plants can recognize "herbivore danger signals" (HDS), which are specific chemicals in oral secretions of insects. This activates a cascade of events in the plant's physiological defense machinery, which leads to the plant developing "immunity" against the predator. However, despite considerable research, exactly how plants recognize these signals has remained a bit of a mystery.
Berkeley -- Living near active oil and gas wells may put pregnant people at higher risk of having low birth weight babies, especially in rural areas, finds a new study of birth outcomes in California.
Tokyo, Japan - Researchers at the Institute of Industrial Science, The University of Tokyo (UTokyo-IIS) used artificial intelligence to rapidly infer the excited state of electrons in materials. This work can help material scientists study the structures and properties of unknown samples and assist with the design of new materials.
A research team led by Kobe University Graduate School of Medicine's Professor OGAWA Wataru (the Division of Diabetes and Endocrinology) and Project Associate Professor NOGAMI Munenobu (the Department of Radiology) has discovered that metformin, the most widely prescribed anti-diabetic drug, causes sugar to be excreted in the stool.
Cholesterol levels are declining sharply in Western nations, but rising in low- and middle-income nations - particularly in Asia, suggests the largest ever study of global cholesterol levels.
The new study, by hundreds of researchers from across the world, was led by Imperial College London and published in the journal Nature.
The research used data from 102.6 million individuals and examined cholesterol levels in 200 countries, across a 39-year time period, from 1980 to 2018.
From the ground, it's impossible to tell that the plateau underfoot is something extraordinary. But from the sky, with laser eyes, and beneath the surface, with radiocarbon dating, it's clear that it is the largest and oldest Mayan monument ever discovered.
Located in Tabasco, Mexico, near the northwestern border of Guatemala, the newly discovered site of Aguada Fénix lurked beneath the surface, hidden by its size and low profile until 2017. The monument measures nearly 4,600 feet long, ranges from 30 to 50 feet high and includes nine wide causeways.
Living in an essentially zero-gravity environment, many deep-sea animals have evolved soft, gelatinous bodies and collect food using elaborate mucus filters. Until now, studying these delicate structures has been virtually impossible. A new study published in the journal Nature describes a unique laser-based system for constructing 3D models of diaphanous marine animals and the mucus structures they secrete.
What The Study Did: The immunologic features of mild and moderate COVID-19 in pediatric patients is described and compared in this case series.

MADISON -Using the Wisconsin H-Alpha Mapper telescope, astronomers have for the first time measured the Fermi Bubbles in the visible light spectrum. The Fermi Bubbles are two enormous outflows of high-energy gas that emanate from the Milky Way and the finding refines our understanding of the properties of these mysterious blobs.
Canadian scientists have achieved a first in the study of telomerase, an essential enzyme implicated in aging and cancer.
In today's edition of the prestigious journal Molecular Cell, scientists from Université de Montréal used advanced microscopy techniques to see single molecules of telomerase in living cells.
What The Study Did: Epidemiology, clinical and laboratory features of 50 children hospitalized with COVID-19 in New York are examined in this case series.
Authors: Philip Zachariah, M.D., M.Sc., of Columbia University Irving Medical Center in New York, is the corresponding author.

A cautious approach to easing lockdown restrictions that reduces the risk of later lockdowns may be better for the global supply chain in the long run, according to a new modelling study led by UCL and Tsinghua University.
The paper, published today in Nature Human Behaviour, is the first peer-reviewed study to comprehensively assess potential global supply chain effects of Covid-19 lockdowns, modelling the impact of lockdowns on 140 countries, including countries not directly affected by Covid-19.
A joint team, while exploring phase diagrams in dense H2-HD-D2 mixtures, has reported a new discovery in which they found counterintuitive effects of isotopic doping on the phase diagram of H2-HD-D2 molecular alloy.
This work was conducted by a research team at the Institute of Solid State Physics, Hefei Institutes of Physical Science collaborating with researchers from the Center for High Pressure Science & Technology Advanced Research and University of Edinburgh. It was published in PNAS on 2 June, 2020.
A new mobile app can help clinicians determine which patients with the novel coronavirus (COVID-19) are likely to have severe cases. Created by researchers at NYU College of Dentistry, the app uses artificial intelligence (AI) to assess risk factors and key biomarkers from blood tests, producing a COVID-19 "severity score."
Current diagnostic tests for COVID-19 detect viral RNA to determine whether someone does or does not have the virus--but they do not provide clues as to how sick a COVID-positive patient may become.
