(Press-News.org) An unprecedented analysis of almost 10,000 Harmful Algal Bloom (HAB) events worldwide over the past 33 years was launched today by UNESCO's Intergovernmental Oceanographic Commission.
The first-ever global statistical analysis examined ~9,500 HABs events over 33 years and found that the harm caused by HABs rises in step with growth of the aquaculture industry and marine exploitation and calls for more research on linkages.
Conducted over seven years by 109 scientists in 35 countries, the study found that reported HAB events have increased in some regions and decreased or held steady in others. A widely-stated view that HABs are on the rise throughout the world, perhaps due to climate change, isn't confirmed.
However, the study, "Perceived global increase in algal blooms is attributable to intensified monitoring and emerging bloom impacts," published in the Nature journal Communications Earth & Environment, creates the world's first baseline against which to track future shifts in the location, frequency and impacts of HABs, which differ depending on which of the 250 harmful marine algae species is involved and where, requiring assessment on a species-by-species and site-by-site basis.
A public webinar on Global HAB Status Report will take place Tuesday Jun 15, 2021 at 1 PM, Paris time. To register: END
UN: More harmful algal bloom impacts emerge amid rising seafood demand, coastal development
UNESCO IOC delivers 1st global assessment report after 7 years' work by 109 experts in 35 countries, creating a baseline to detect and gauge the changing distribution, frequency, and intensity of harmful -- often poisonous -- algal blooms

How COVID-19 wreaks havoc on human lungs
2021-06-08
UPTON, NY--Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have published the first detailed atomic-level model of the SARS-CoV-2 "envelope" protein bound to a human protein essential for maintaining the lining of the lungs. The model showing how the two proteins interact, just published in the journal Nature Communications, helps explain how the virus could cause extensive lung damage and escape the lungs to infect other organs in especially vulnerable COVID-19 patients. The findings may speed the search for drugs to block the most severe effects of the disease.
"By obtaining atomic-level details of the protein interactions we can explain why the damage occurs, and search for inhibitors ...
Experiments show natural selection opposes sexual selection
2021-06-08
Natural selection can reverse evolution that occurs through sexual selection and this can lead to better females, new research shows.
The study - led by the University of Exeter and Okayama University - examined broad-horned flour beetles, whose males have exaggerated mandibles, while females do not.
Male beetles with the largest mandibles win more fights and mate with more females - an example of "sexual selection", where certain characteristics (like a male peacock's tail) improve mating success.
However, having bigger mandibles requires a masculinised body (large head and neck), ...
Scientists can predict which women will have serious pregnancy complications
2021-06-08
Women who will develop potentially life-threatening disorders during pregnancy can be identified early when hormone levels in the placenta are tested, a new study has shown.
Pregnancy disorders affect around one in ten pregnant women. Nearly all of the organ systems of the mother's body need to alter their function during pregnancy so that the baby can grow. If the mother's body cannot properly adapt to the growing baby this leads to major and common issues including fetal growth restriction, fetal over-growth, gestational diabetes, and preeclampsia - a life-threatening high blood pressure ...
Projected acidification of the Great Barrier Reef could be offset by ten years
2021-06-08
New research has shown that by injecting an alkalinizing agent into the ocean along the length of the Great Barrier Reef, it would be possible, at the present rate of anthropogenic carbon emissions, to offset ten years' worth of ocean acidification.
The research, by CSIRO Oceans and Atmosphere, Hobart, used a high-resolution model developed for the Great Barrier Reef region to study the impact of artificial ocean alkalinization on the acidity of the waters in the Great Barrier Reef. The study is based on the use of existing shipping infrastructure to inject a source of alkalinity into the ocean, which could also be considered as an acceleration of the chemical weathering of minerals through natural ...
HKUST-Beijing Tiantan Hospital researchers discover a new cause for the cerebral cavernous malformation
2021-06-08
Researchers from the Hong Kong University of Science and Technology (HKUST) and Beijing Tiantan Hospital have recently uncovered a new gene mutation responsible for the non-familial patients of cerebral cavernous malformation (CCM) - a brain vascular disorder which inflicted about 10~30 million people in the world.
While the mutation of three genes: namely CCM1, CCM2, and CCM3, were known to be a cause of CCM - they mostly targeted patients who has family history in this disorder - which only account for about 20 per cent of the total inflicted ...
Consumers spent less on candy and desserts when shopping online

Orphans and exiles: Research shows the impact of family separation
2021-06-08
BINGHAMTON, N.Y. -- New research from Binghamton University, State University of New York shows the human trauma and family separation that resulted from the Trump Administration's zero tolerance policy on undocumented immigration.
The news reports surrounding the Trump Administration's "zero tolerance" policy on undocumented immigration were stark: children separated from their parents, uncertain whether they would ever see them again.
All told, the official zero tolerance policy lasted only a few months, from April to June 2018. But family separations occurred before and after those dates: at least 5,512 children were separated from their families since July 2017, and 1,142 families were separated ...
Early endeavors on the path to reliable quantum machine learning
2021-06-08
Anyone who collects mushrooms knows that it is better to keep the poisonous and the non-poisonous ones apart. Not to mention what would happen if someone ate the poisonous ones. In such "classification problems", which require us to distinguish certain objects from one another and to assign the objects we are looking for to certain classes by means of characteristics, computers can already provide useful support to humans.
Intelligent machine learning methods can recognise patterns or objects and automatically pick them out of data sets. For example, they could pick out those pictures from a photo database that show non-toxic ...
Super productive 3D bioprinter could help speed up drug development
2021-06-08
A 3D printer that rapidly produces large batches of custom biological tissues could help make drug development faster and less costly. Nanoengineers at the University of California San Diego developed the high-throughput bioprinting technology, which 3D prints with record speed--it can produce a 96-well array of living human tissue samples within 30 minutes. Having the ability to rapidly produce such samples could accelerate high-throughput preclinical drug screening and disease modeling, the researchers said.
The process for a pharmaceutical company to develop a new drug can take up to 15 years and cost up to $2.6 billion. It generally begins with screening tens of thousands of drug candidates in ...
In youth, COVID-19 causes more complications than flu; fatality is rate
2021-06-08
NEW YORK, NY--A new global study of 30-day outcomes in children and adolescents with COVID-19 found that while death was uncommon, the illness produced more symptoms and complications than seasonal influenza.
The study, "30-day outcomes of Children and Adolescents with COVID-19: An International Experience," published online in the journal Pediatrics, also found significant variation in treatment of children and adolescents hospitalized with COVID-19.
Early in the pandemic, opinions around the impact of COVID-19 on children and adolescents ranged from it being no more than the common flu to fear of its potential impact on lesser-developed immune systems. This OHDSI global network study compared the real-world observational data of more ...
