The measures taken during the COVID-19 pandemic limited the access of citizens to natural objects. It is still unexplored, what consequences this had for the residents and what conclusions should be drawn for more effective urban planning. RUDN University scientists with colleagues from Australia and Germany studied how the restrictions associated with COVID-19 affected the use of blue and green infrastructure by citizens in Moscow (Russia) and Perth (Australia), and what consequences this had for their health.
Astronomers have designed and trained a computer program which can classify tens of thousands of galaxies in just a few seconds, a task that usually takes months to accomplish.
In research published today, astrophysicists from Australia have used machine learning to speed up a process that is often done manually by astronomers and citizen scientists around the world.
The Mid-infrared lasers (MIR) with high peak power and high repetition rate operating in the range of 2.7~3 μm have important application in laser surgery and optical parametric oscillator (OPO).
A recent study conducted by SUN Dunlu's research group at the Hefei Institutes of Physical Science(HFIPS) of the Chinese Academy of Sciences (CAS) achieved high power, high efficiency and quasi-continuous mid-infrared laser in the free running and langasite [La3 Ga5 SiO14 (LGS)] Q-switched modes by using the Er3+ ions-doped YAP crystals as laser gain medium.
In 2016, researchers from the EDDyLab - Evolution & Diversity Dynamics Lab - at the University of Liège (Belgium) proposed a new definition of the geological boundary between the Devonian and Carboniferous periods (359 million years). This new definition has been tested by hundreds of researchers around the world and the results are now compiled in a special issue of the journal Palaeodiversity & Palaeoenvironments.
Scientists from Tohoku University and the University of Maryland have pinpointed the strong magnetic field of the early sun as the reason behind the radial variation of rock and metal in rocky planets' cores. This magnetic field, which pulled small iron grains inward, explains Mercury's big iron core and why Mars has so little iron in its core.
The details of their research were published in the journal Progress in Earth and Planetary Science on July 5, 2021.
The study is the first on epidemiology and causes of traumatic brain injury in over 20 years. The research team reports in the journal BMJ Open of 4 June 2021.
Falling and cycling without a helmet are common causes
Together with their multifaceted action mechanisms, activation-induced cytidine deaminase (AID) and so-called APOBEC proteins are important factors in the body's immune response and offer fast and effective protection against a large number of DNA and RNA viruses. The task of AID is to strengthen the human immune response, while APOBECs are able to block the virus.
Sleep deprivation - from lifestyle choices, pandemic stress, or late-night computer study - can quickly lead to loss of energy and function during the day and even feelings of anger and depression, an Australian sleep institute study has shown.
The study, led by Flinders University, asked 34 health teenagers (20 males) aged between 15 and 17 to spent 10 days and nine nights in a specially designed sleep centre.
Dysmenorrhea, that is, frequent severe and painful cramps during menstruation from abnormal contractions of the uterus, is the most common of all gynecological disorders. It affects between 16-91% of girls and women of reproductive age, of whom 2%-29% have symptoms severe enough to restrict their daily activity. Now, for the first time, researchers from China Medical University Hospital in Taiwan have shown that long-term exposure to air pollutants such as nitrogen and carbon oxides and fine particulate matter greatly raises the risk of developing dysmenorrhea.
A study led by University of Barcelona researchers and carried out together with more than 1,650 students and their family members from 18 educational centres in Barcelona shows that citizen science is a valid approach able for doing high quality science, and in this case, able to provide nitrogen dioxide values with an unprecedented resolution and to assess the impact of the pollution in the health of their inhabitants.
Although hypomorph mammals (or equids) are currently represented by only one genus ('Equus') and just a handful of species of horses, donkeys and zebras, they were more diverse during the Eocene epoch (between 56 and 33.9 million years ago). One of the most widespread groups in Europe, which was an archipelago at that time, were the palaeotheriidae, named after the genus 'Palaeotherium', described in 1804 from fossils originating in the quarries of Montmartre (Paris) by the famous French naturalist George Cuvier.
Big hydropower plants are an important source of clean and cheap electricity for many countries in Southeast Asia. However, dams harm the environment and have dire consequences on local communities. Building more dams would therefore pose major trade-offs between electricity supply and environmental protection.
TAMPA, Fla. (July 6, 2021) - All it takes is three consecutive nights of sleep loss to cause your mental and physical well-being to greatly deteriorate. A new study published in Annals of Behavioral Medicine looked at the consequences of sleeping fewer than six hours for eight consecutive nights - the minimum duration of sleep that experts say is necessary to support optimal health in average adults.
Announcing a new article publication for BIO Integration journal. In this article the authors Daowei Lin, Zhixiao Han, Yanni Fu, Xiaoqiu Zhu, Jin Li, Hui Xu, Jing Wen, Fei Wang and Mingyan Guo from Sun Yat-sen University, Guangdong, China, The First Affiliated Hospital of Zhengzhou University, Zhengzhou, Henan, China and University of Virginia, Charlottesville, VA, USA discuss how interscalene brachial plexus block combined with general anesthesia attenuates stress and inflammatory response in arthroscopic shoulder surgery.
Historically most scientists thought that once a satellite galaxy has passed close by its higher mass parent galaxy its star formation would stop because the larger galaxy would remove the gas from it, leaving it shorn of the material it would need to make new stars. However, for the first time, a team led by the researcher at the Instituto de Astrofísica de Canarias (IAC), Arianna di Cintio, has shown using numerical simulations that this is not always the case.
