The multi-year debate over the conservation of the Bears Ears and Grand Staircase-Escalante National Monuments has focused on the tension between preserving the history and culture of the Indigenous peoples who have inhabited the region for centuries, and the efforts to exploit natural resources.

But on Friday, President Joe Biden gave the monuments new meaning when he restored their original boundaries in southern Utah and highlighted public lands as a tool in the fight against the climate.

White House climate adviser Gina McCarthy linked global warming to the president’s commitment to conservation as she opened the White House ceremony in which Biden signed proclamations restoring boundaries , which former President Donald Trump had cut back to pave the way for fossil fuel exploration.

Sitting at an ornate wooden desk on the North Lawn, Biden also signed a proclamation restoring the Northeast Canyons and Seamounts National Monument in the Atlantic Ocean, southeast of Cape Cod, which had was designated in 2016, but was then reopened to commercial fishing by Trump in 2020.

McCarthy, who led the US Environmental Protection Agency in the Obama administration, said these protections harness the power of soil, trees and water to build resilience against climate impacts facing the world. is already facing.

“Taking advantage of these natural climate solutions will protect public health,” she said. “They will protect us against climate impacts. “

The signing came as Biden prepares to attend next month’s annual United Nations climate change conference in Scotland with virtually empty hands as most of his climate agenda remains in limbo, caught up in a battle of $ 3.5 trillion on a spending plan that would expand the social safety net and implement a first-ever U.S. greenhouse gas reduction policy in time to avoid the worst damage from global warming.

At Friday’s ceremony, the president quoted scientists who believe that protecting and restoring natural lands and water can “provide nearly 40% of the solution to climate change.” And he underscored his goal of halving U.S. emissions by 2030 and bringing the country back to net zero emissions by 2050.

“Achieving these ambitious goals will require nature itself to be a player,” he said, before signing the proclamations that restore more than 2 million acres to Utah monuments.

Utah’s Republican political leaders denounced the move. During Trump’s presidency, they lobbied the administration to downsize the Grand Staircase-Escalante National Monument, created by President Bill Clinton in 1996, and Bears Ears, which President Barack Obama created in 2016 at the behest of the five tribes with the deepest ties to the region’s rich cultural and natural history.

Now they condemn Biden’s decision to reverse the Trump-era borders that reopened access to the abundant deposits of coal, uranium, oil and gas that lie beneath the severely cut landscape. blast of red rock.

Redge Johnson, executive director of Utah’s Public Lands Policy Coordinating Office, pointed out that by refusing to work with Congress on monuments, the Biden administration may also have restricted some important climate tools.

Uranium deposited in and around Bears Ears could help fuel US nuclear reactors. The lithium reserves could be used there for the batteries needed for the transition to renewable energies. Forest treatments which are now prohibited by monument rules could have prevented forest fires and their emissions.

“We missed an opportunity there,” Johnson said.

In the nearly four years that the Trump administration has rewritten the resource management plans that dictate how land can be developed, the rush to mine for coal or tap into oil and gas reserves has failed. is never materialized.

In March, the Utah Geological Survey detailed the average opportunities for fossil fuel development within the original boundaries of the two monuments. There have been no new applications for permits to drill for oil and gas at Bears Ears, according to the report, and 300 oil and gas wells that had been drilled or proposed before the monument boundary controversy have remained. inactive. None have been active since 1992.

The original Grand Staircase-Escalante National Monument, where the Kaiparowits Plateau holds 58.5% of Utah’s coal reserves, has “high” potential reserves, state geologists said.

Steve Bloch, a lawyer for the Southern Utah Wilderness Alliance, who has fought downsizing in federal court, said the energy claims were so distant that they were unlikely to ever pay off. But conservation groups were concerned, as doors remained open to fossil fuel development on about 2 million acres that had once been protected by monuments.

“Under Trump, and as part of the ‘energy domination’ program, we had every reason to believe that there would be a new coal mine in the Grand Staircase, whether they would tackle the tar sands or the shale. bituminous or that there would be speculation the extraction of uranium or the leasing of oil and gas, ”he said.

The new proclamations put an end to these risks because the statute of monument prohibits any new development on public lands.

For long-term climate protection, this restriction could prove important, according to Laura Hilberg of EcoAdapt, who produced a report for SUWA a year ago detailing the potential for climate mitigation and adaptation of extended protection of nature in Utah.

“There are a lot of greenhouse gases that would not be released into the atmosphere if all the oil, gas and coal in those areas were kept in the ground,” said Hilberg, a scientist at the climate adaptation.

Ultimately, the border restores seem to underscore a message that tribal advocates brought to the negotiating table when they first pitched their Bears Ears idea to the Obama administration. For the indigenous peoples of the region, every landscape is part of the natural world upon which all life and everyone depends.

Home Secretary Deb Haaland, a Laguna Pueblo citizen whose ancestors lived in the area, appeared to have the idea in mind during Friday’s signing ceremony. Her voice trembling with emotion, she said, “This is a place that must be protected in perpetuity for every American and every child in the world.”

There is no better way to learn how to protect the earth’s natural wonders than by exploring. Just ask Jordan Elliot-Murray, a nature lover with the utmost respect for the marine and terrestrial environment. To gain the scientific knowledge, skills and practical experience necessary to launch a rewarding career, she decided to pursue a BSc (Hons) Ocean Science and Marine Conservation at the University of Plymouth.

In just her second week, Elliot-Murray realized that the university’s approach to education –– “learn by doing” –– was true. Life jacket and all, she ended up at sea, aboard the RV Falcon Spirit –– a 14-meter science catamaran –– which is used, alongside a fleet of smaller boats, for practical work in group and individual project work. His class was on their way to collect water samples. Ashore, they surveyed local beaches to assess storm erosion.

“The amount of technology, equipment and opportunities they have is incredible,” she says. “This is only our second week in Plymouth and we are already on boats, we are already at the ferry station and we are already having a fantastic time.”

In the face of increasing coastal erosion, pollution and threatened ecosystems, the School of Biological and Marine Sciences at the University of Plymouth is fighting to highlight the importance of the world’s oceans as a precious natural resource . To train students to become protectors of marine environments, the top-ranked university offers an educational experience of a lifetime that steadily extends beyond classrooms and UK borders.

Experiences like Elliot-Murray’s are the norm, as are trips to the Caribbean, Portugal, South Africa, Sweden, France, etc. In Plymouth itself, a natural laboratory, students have access to the Marine Station, a historic £ 4.65million development located on the shores of Plymouth Sound – the UK’s first national marine park.

It is no coincidence that this natural laboratory has one of the highest concentrations of world-class marine institutions, which, in addition to the university, includes: the Plymouth Marine Laboratory, the Marine Biological Association and the National Marine Aquarium. The teaching and research of the University benefit from close links between all these organizations. The University of Plymouth is also unique in offering its students the opportunity to obtain the HSE Professional SCUBA certification in addition to their degree.

New research by SFU archaeologists could help forensic teams in their work to estimate the age of child remains found during archaeological work or in criminal investigation cases. Their study is published in the journal International forensic sciences.

Although age is usually determined by dental records or other methods, such as measuring the long bones of the upper or lower extremities, these methods may not always be possible, especially in the case of young children. The researchers turned to another approach: measuring the skull and mandibular bones, located in the skull.

For their study, the researchers measured these bones in the skeletal remains of children of known sex and age from the collections of the Natural History Museums in Lisbon, Portugal and London, UK. The bones were from 185 children from birth to 12.9 years old who lived between 1700 and 1900. The measurements have been shown to provide a valid and comprehensive approach to estimating the age of juveniles.

According to SFU forensic anthropologist Hugo Cardoso, age, combined with gender, background and other skeletal characteristics, helps determine who the child might be from a list of potential candidates. . Families can then provide a DNA sample to confirm the identity of the child whose remains have been found, resulting in the family being shut down.

“It is important to estimate the age of the child’s remains, as it helps with identification, especially in criminal investigations,” says Deanna Smith, study leader, master’s student in archeology at SFU and member of the Wikwemikong First Nation. Determining the age of the remains can help narrow the pool of possibilities from a list of hundreds of missing children of varying ages, for example.

Researchers assist in a variety of situations where identification of remains is sought, from criminal investigations to cases where medical records are insufficient to estimate age. “As physical anthropologists, we are often called upon to identify found human remains, which are then subjected to a forensic investigation into the death,” explains Cardoso, chairman of the Department of Archeology and co-director of the Center for Forensic Research.. “We are also involved in the study of remains intentionally found in archaeological projects, such as the excavation of a prehistoric or historic cemetery.”

Cardoso adds that in other archaeological contexts, the excavation of cemeteries can provide a snapshot of the entire population in a certain period of time and in a certain geographic area, allowing researchers to learn more about how which people lived in the past, and age determination is a key factor. “Estimating age can help researchers reconstruct population demographics and better understand aspects of nutrition, health and stress during growing years. “

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is associated with a high overall risk of morbidity and mortality in patients with co-morbidities. In COVID-19 patients, hypertension, obesity and diabetes mellitus were found to be the most common comorbidities

The majority of patients who have been infected with SARS-CoV-2 test negative 14 days after the initial infection, while some patients may remain RNA positive for months. The recent emergence of re-infections, vaccine discovery, and VOC variants of concern, such as the Delta variant, with increased viral titers observed, underscores the clinical imperative to interpret positive SARS results. CoV-2 from the same person.

The current gold standard test for SARS-CoV-2 is the RT-PCR clinical diagnostic test, however, this test is not quantitative. The Ct values ​​obtained from the RT-PCR test are inversely correlated with the amount of RNA present in a sample, but they are influenced by the characteristics of the sample, the patient and the diagnostic test.

In a new study, a collaboration of researchers from various institutes described the natural history of the SARS-CoV-2 test, which includes Ct values ​​in patients who had tested positive multiple times, before the emergence of VOCs. in the deployment of the vaccine. In addition, the authors analyze the timescale of positivity and clinical characteristics of the patient population with prolonged positivity for SARS-CoV-2.

A pre-printed version of this study, which is yet to be peer reviewed, is available on the website medRxiv* preprint server.

Characteristics of diagnostic tests for patients with multiple positive tests for SARS-CoV-2

Of the 207 patients who had multiple positive tests in this study and who did not display prolonged positivity, 17 showed patterns of intermittent positivity due to having at least one negative test between their first and last positive test. This intermittent positivity was observed three times more among the 57 patients who displayed prolonged positivity in this study.

RT-PCR Ct values ​​generally decrease over time, but varying rates of decline were observed in patients in this study. Of the patients who had shown prolonged positivity, 123 had available Ct values, obtained from their first and last positive tests.

Among these patients, the final positive tests were above the median of 9.8 cycles compared to the first positive test, indicating that lower amounts of RNA were detected. However, 11 of these patients had higher amounts of RNA in their last positive test compared to their first.

Overall, final positive tests ranged from 22.5 fewer cycles to 31.8 more cycles, with final positive tests near the limit of detection (> 35) for 21 patients. The first and last test Ct data were available for 36 of the patients who had prolonged positive tests. The final positive tests were a median 14 cycles higher than the first positive tests.

Unlike patients without prolonged positivity, there were no patients with prolonged positivity who had lower terminal test Ct values ​​than their first positive test.

Of the prolonged positive patients, 33 had positive tests near the limit of detection (> 35Ct), which is consistent with the decline of viral DNA over time. However, after the first positive test, on day 40, 5 patients still had Ct values ​​<35, and one patient was positive, with a Ct value <35 109 days after the initial positive test.

Implications

Results from 8% of patients showing intermittent positivity with multiple positive tests for SARS-CoV-2 prior to sustained VOC transmission suggest that sample quality plays an important role in Ct results.

Interestingly, a prolonged positive patient was three times more likely to display intermittent positivity. Thus, intermittent negative results in some patients may be due to therapeutic interventions, varying excretion dynamics, among other variables, which should be explored in future studies.

As the pandemic continues to progress and as VOCs capable of higher titers and vaccine advances such as the Delta variant become more prevalent, information on longitudinal testing with variability in CT values ​​will be more accessible for a larger number. of patients.

Due to the addition of new circulating variants, it will become essential to keep in mind the possibility of variable excretion at any stage of infection and to be careful in interpreting the values. Ct as proxy measures of severity and infectivity.

There is an urgent need for diagnostic tests to be developed and deployed that can distinguish between reinfection and prolonged shedding, which will provide insight into infectivity and aid in future stages of the pandemic.

The importance of network security should never be underestimated. In today’s world, there is no room to be lax when it comes to network security.

This is what the growing number of large-scale cyber attacks which are more and more widespread.

Here we highlight the capabilities of several major network security providers through case studies in all industries:

4 network security case studies

1. Network security: Palo Alto Networks

Palo Alto Networks is a global cybersecurity company serving the network security needs of many customers. They also need these same services. They have, for example, deployed zero trust internally to ensure the protection of their digital sphere. To do this, they used a five-step strategy that involved the following:

  1. Define the protection surface
  2. Map transaction flows
  3. Building a zero trust architecture
  4. Create a zero trust policy
  5. Monitor and maintain

By implementing this zero confidence solution, Palo Alto Networks has joined the companies they serve to secure their network.

2. Internet Service Provider (ISP): NexusOcean

NexusOcean provides internet services to offshore energy and shipping companies. Their service must be reliable and secure. To ensure the security of its network, NexusOcean has integrated Fortinet’s Secure SD-WAN into its offer. With this configuration, they are able to offer customized security capabilities to protect clients’ network traffic. This is all the more important as ships are increasingly vulnerable to cyber attacks, including the engine room and navigation equipment. Fortinet’s SD-WAN solution, combined with FortiManager and FortiAnalyzer, provides fast Internet access that meets highest maritime standards for network security.

3. Sports: Major League Baseball (MLB)

Major League Baseball goes above and beyond to ensure fans a fast, stable and secure streaming experience. MLB has partnered with Okta to make it a possibility, using solutions such as a zero trust framework. Additionally, with Okta’s technology, Major League Baseball is able to have a consistent layer of security throughout the organization. By working with Okta and implementing its Zero Trust Framework, MLB not only improved safety at all associated baseball clubs, but was also able to deliver a more streamlined customer experience. They were also able to free up development resources which can now be dedicated to other development issues.

4. Museums: Natural history museum

The Natural History Museum in the UK is one of Britain’s most popular tourist attractions and a major operation. In the past, their approach to security was disjointed and they needed a solution to unite everything related to privacy. With by OneTrust Technology and services, they have been provided with a centralized access point for critical data protection tasks. The museum is now able to access tasks, such as record keeping and assessments, from a central hub. Additionally, employees better understand the importance of privacy in their roles, which helps improve privacy compliance and network security at all levels.

By Theresa Waldrop

Google honored María de los Ángeles Alvariño González with a Doodle on Sunday, the 105th birthday of the marine research biologist “widely regarded as one of the most important Spanish scientists of all time,” Google said.

Alvariño discovered 22 new species of zooplankton and published more than 100 scientific papers, according to Google and the scientist’s biographies.

The Spanish Institute of Oceanography (IEO) appointed her as a marine biologist in 1952, although only men were accepted into the institute at the time, due to her impressive work at the university, Google said.

Born in Serntes on the Spanish coast, Alvariño developed a love for natural history early on, encouraged by her parents to read her doctor’s books on zoology, according to Encyclopedia of World Biography.

Her father did not support her wish to become a doctor herself, and Ángeles Alvariño continued to study natural sciences at the University of Madrid, according to the biography.

A scholarship from the British Council took her to the Marine Biological Laboratory in Plymouth, England, to study zooplankton, including jellyfish.

The scholarship “enabled her to become the first woman to work as a scientist aboard a British research vessel,” Google wrote.

She continued her research with a Fulbright Fellowship in the United States and became a United States citizen in 1966, according to the encyclopedia’s biography.

“Today, Ángeles Alvariño is the only Spanish scientist in 1,000 in the Encyclopedia of Scientists of the World,” Google wrote, “and a modern research vessel in the IEO fleet bears his name.”

Alvariño died in 2005.

These mysterious animal burrows seem to pre-date animals.

Scientists have just solved a 50-year-old geological conundrum: the mystery of ancient animal tracks dating back to an era prior to the evolution of animals on Earth.

The traces in question are embedded in quartzite rock, discovered at Mount Barren in southwest Australia, and they closely resemble the burrows that crustaceans dig in the sand. The only problem is that the rock would have solidified from the sand about 600 million years before the appearance of animal life.

It seemed that either the animals were digging much earlier than previously thought, or some species had developed teeth capable of gnawing at solid rock. And no explanation was particularly plausible.

“Quartzite is as hard as concrete and impossible for burrowing animals to penetrate,” says paleontologist Bruce Runnegar of the University of California, Los Angeles (UCLA). “The tracks should therefore have been made while the sand was still loose.”

“But the sand was deposited 1.7 billion years ago – a billion years before the first animals appeared in the fossil record, and its transformation into quartzite occurred over 1 , 2 billion years old, much earlier than the oldest animal fossils, which are less than 0.6 billion years old. “

A new study provides an explanation: The sand that formed the burrows is actually much younger than much of the quartzite that surrounds it. The trace fossils are now believed to be around 40 million years old, made in the Eocene epoch.

The mysterious terriers were first described in an article in 1977, but the team decided to revisit them using some of the latest technology.

Using a variety of radioactive materials and scanning techniques, including scanning electron microscopy, the researchers were able to more accurately identify the age of the animals’ burrows. Further investigation revealed that the first breaks in the rock were made at surface level.

What appears to have happened is that inclement weather and flooding opened a window of opportunity for burrowing creatures to explore the rock, which then hardened again. Similar geological processes have been observed elsewhere – in the stones of Stonehenge, for example, and quartzite caves in Venezuela.

“The age turned out to be over a billion years younger than the encompassing quartzite,” says geologist Birger Rasmussen of the University of Western Australia. “So the burrows could have been dug by animals.”

The team believe it is likely that the animals in question were crustaceans, invading southwest Australia following the expansion of the Southern Ocean at the time. The contemporary climate would have been humid and temperate to tropical.

Fossil traces like these – so named because they show the activity of animals rather than the animals themselves – are among the oldest evidence of complex life on our planet that scientists have.

Wherever they are found, fossils can tell us more about when organisms evolved to become more sophisticated and how certain species began. Part of this means that the dates are as precise as possible.

“These traces of fossils in ‘bad’ rocks have been a mystery for half a century,” says paleontologist Stefan Bengtson of the Swedish Museum of Natural History. “We are happy to have been able to demonstrate geological processes that solve this puzzle.”

The research was published in PNAS.

Dr. Priscilla Croswell Grew, a geologist who has held numerous positions at the University of Nebraska-Lincoln, was recently honored at the 121st State Conference of the Daughters of the American Revolution in Michigan. State Regent Kelly VanWormer presented her with the NSDAR Women in American History Award.

Grew has been a member of the DAR for 47 years. Her original chapter is the Lucy Wolcott Barnum chapter in Adrian, Michigan, where her family has deep roots. His grandfather, Charles M. Croswell of Adrian, was Michigan’s 17th Governor from 1877 to 1881. His second wife, Elizabeth Musgrave, paved the way for him to attend Bryn Mawr College and earn a degree in geology. She then obtained a doctorate from the University of California-Berkeley. The old family home was donated by Elizabeth Musgrave Croswell to Chapter Lucy Wolcott Barnum.

Grew has had a long and varied career, although it all has to do with his love for geology. She started as an assistant professor at Boston College, where she participated in a research excursion to Lake Baikal in Siberia. She was the first woman to visit the region. She then moved to California, where she applied geoscience to public policy and worked with earthquake and landslide risk mitigation and geothermal energy. In 1977, she became director of the California Department of Conservation and later commissioner of the California Public Utilities Commission. Continuing with geology, she was director of the Minnesota Geological Survey, which conducted research on Precambrian and glacial geology, groundwater, and mineral resources.
