NASA: New Software Assesses Threats from Asteroids More Accurately

The Jet Propulsion Laboratory (JPL) of the U.S. space agency, NASA, says it has new software that will allow its Center for Near Earth Object Studies (CNEOS) to better assess potential threats posed by asteroids that can come close to Earth. 

In a press release on Monday, NASA astronomers said they have upgraded their impact software, called Sentry, with its next generation, Sentry-II, to better evaluate near-Earth asteroid (NEA) impact probabilities. 

NASA said to date, almost 28,000 NEAs have been found by survey telescopes that continuously scan the sky, making about 3,000 new discoveries per year. But with better technology and newer, bigger telescopes scheduled to come online, that number is expected to multiply quickly, necessitating the software upgrade. 

Contrary to what some might believe, asteroids are extremely predictable celestial bodies that obey the laws of physics and follow knowable orbital paths around the sun, NASA scientists say. Sometimes, when those paths bring those objects closer to Earth’s future position in space, uncertainties in the asteroids’ path raise the possibility of a collision with Earth. 

Navigation engineer Javier Roa Vicens, who had led the development of Sentry-II while working at JPL and recently moved to SpaceX, said the first generation of Sentry was “very capable.” He said that in less than an hour, it could produce the impact probability for a newly discovered asteroid for the next 100 years, what he called “an incredible feat.” 

But JPL scientists say the Sentry-II software can rapidly calculate impact probabilities for all known NEAs, including some special cases not captured by the original Sentry. For example, its calculations consider how the sun’s heat and Earth’s own gravity affect the trajectory of asteroids. 

The scientists say that by systematically calculating impact probabilities in this new way, the impact monitoring system is more robust, enabling NASA to confidently assess all potential impacts with odds as low as a few chances in 10 million. 

Since 2002, the JPL-managed CNEOS, at its headquarters in Southern California, has calculated every known NEA orbit to improve impact hazard assessments in support of NASA’s Planetary Defense Coordination Office.

South African Tech Firm Creates App to Tackle Gender-Based Violence

In the shadows of the coronavirus pandemic, violence against women has been on the rise around the world, including in South Africa, where half of the country’s women report at least one incident of violence in their lifetime. Now, a local tech company has developed an alarm system to help stop the abuse.

A click of a button could save a woman’s life. That’s what South African firm Afri-Tec Technologies hopes to achieve with its alert app.

Gender-based violence has become so rampant during coronavirus lockdowns, President Cyril Ramaphosa has called it the country’s “second pandemic.”

Afri-Tec presents its app as one solution, allowing users to discretely alert friends, family and authorities that they are in danger.

“We’re not saying that our tech or our solution is the silver bullet. But it certainly is one of the pieces of this big puzzle that can make a difference. And I think COVID became a catalyst for a lot of people to adopt, a lot more people to adopt technology. And hence, why we felt creating a technological solution,” says AB Moosa, the CEO of Afri-Tec Technologies. 

The South African Police Service says more than 10,000 people were raped between April and June this year.

Another 15,000 cases of domestic violence were reported in the same period.

Organizations providing support to survivors say those figures don’t paint a full picture as many more cases go unreported.

The lack of data about the crisis is another solution Afri-Tec plans to provide with the information it collects from users.

“We’re also putting AI systems behind our app to be able to then hopefully predict trends of what’s going to happen. So, empower police stations, empower private security, power NGOs, to then be able to have a proactive, rather than reactive response to this challenge,” said Moosa.

People without smartphones can still use the alert system.

The company has designed a panic button that looks like a USB stick as well as a wristwatch that provide the same response.

Social workers say these interventions will make a big difference — but more is still needed.

“We need to target families, ask why is this happening? Is it a tradition? Is it your family history? Is that your background? And if so, how can we change it? And ultimately, we need to pay attention to our children. What are we teaching them?” asks Lisha Stevens, a social worker at the Nisaa Institute for Women’s Development in Johannesburg.

Advocates like Stevens say the public as a whole need to be educated on what gender-based violence is and how to respond to it.

“How do we break the cycle with my attitude, my view of what gender-based violence is? I’m a neighbor, I see this happening. I close my door and I go inside. So, where’s the disconnect that we need to understand?” said Stevens.

Witnesses of violence can report incidents to police, or via a national hotline, or nonprofits — and they can do so anonymously.

If more people intervened, Stevens believes it could be life-changing for victims and help shift the culture so that gender-based violence is no longer the norm.

COVID-19 Disruptions Linked to Rise in Malaria Infections, Deaths

The World Health Organization reports a significant rise in malaria cases and deaths in 2020 due to COVID-19 disruptions in malaria services.

Over the past two decades, global malaria death rates have been cut in half, saving the lives of 10.6 million people. New data gathered by the WHO show COVID-19 has stopped and even reversed the progress made in reducing deaths from this preventable, treatable disease.

The WHO’s World Malaria Report estimates 241 million malaria cases and 627,000 malaria deaths globally have occurred in 2020.This represents an increase of 14 million cases and 69,000 deaths compared to the previous year. WHO links the increase to disruptions of malaria prevention, diagnosis, and treatment services during the pandemic.

Director of WHO’s Global Malaria Program, Pedro Alonso, said the situation could have been far worse. The good news, he said is that the predicted doomsday scenario did not transpire. He notes gloomy projections made in March 2020 of a huge spike in malaria have not materialized.

“One worst case scenario implied a doubling of malaria deaths. So, let me reiterate this, that is not the case. We can call this a success story, even though an extra 47,000 people have died as a consequence of the disruptions,” said Alonso.

The report finds progress in the global fight against malaria remains uneven.

Between 2000 and 2020, WHO has certified 12 countries as being malaria-free. Two countries, China and El Salvador, have achieved this status in 2021, despite the ongoing pandemic.

Since 2015, both cases and deaths have stalled in most of the world’s 93 endemic countries and territories. However, other figures show malaria cases have increased in 32 countries, most in Sub-Saharan Africa and some in South America.

Alonso said the situation remains especially precarious in Africa, where the malaria burden remains unacceptably high. He notes Africa accounts for about 96 percent of global deaths, 80 percent among children under age five.

“At the same time, the pandemic is not over, and the pace of economic recovery is uncertain. Without immediate and accelerated action key 2030 targets of the WHO Global technical strategy will be missed, and additional ground may be lost,” he said.

WHO’s strategy calls for a 90-percent reduction in malaria cases and deaths by 2030.It also presses for the elimination of malaria in at least 35 countries and for the prevention of disease resurgence in all countries that are malaria-free.

Reports: Biden Administration Expected to Announce Diplomatic Boycott of Beijing Winter Games

U.S. news outlets say the Biden administration is expected to announce a diplomatic boycott of the upcoming 2022 Beijing Winter Olympic Games.

A diplomatic boycott means no U.S. officials would attend any events of the Beijing 2022 Games, while still allowing athletes on Team USA to participate.

That would avoid a repeat of 1980, when then-President Jimmy Carter kept U.S. athletes from attending the Moscow Summer Games because of the Soviet Union’s invasion of Afghanistan in late 1979.

CNN was first to report the expected announcement. 

In Beijing Monday, Chinese Foreign Ministry spokesman Zhao Lijian accused U.S. lawmakers who have been pressuring President Joe Biden for a diplomatic boycott of the Games of “grandstanding,” and warned China would take “countermeasures” if Washington were to go through with the boycott. 

Biden said last month he was considering a diplomatic boycott due to criticism of China’s human rights abuses, including the detention of millions of Muslim Uyghurs in Xinjiang province and the crackdown on pro-democracy forces in Hong Kong.

The Beijing Winter Olympics will run from February 4-20. 

Some information in this report came from Reuters and the Associated Press.

Dictionary.com Anoints Allyship Word of the Year for 2021

Allyship, an old noun made new again, is Dictionary.com’s word of the year. 

The look up site with 70 million monthly users took the unusual step of anointing a word it added just last month, though “allyship” first surfaced in the mid-1800s, said one of the company’s content overseers, John Kelly. 

“It might be a surprising choice for some,” he told The Associated Press ahead of Tuesday’s unveiling. “In the past few decades, the term has evolved to take on a more nuanced and specific meaning. It is continuing to evolve and we saw that in many ways.” 

The site offers two definitions for allyship: The role of a person who advocates for inclusion of a “marginalized or politicized group” in solidarity but not as a member, and the more traditional relationship of “persons, groups or nations associating and cooperating with one another for a common cause or purpose.” 

The word is set apart from “alliance,” which Dictionary.com defines in one sense as a “merging of efforts or interests by persons, families, states or organizations.” 

It’s the first definition that took off most recently in the mid-2000s and has continued to churn.  

Following the summer of 2020 and the death of George Floyd, white allies — and the word allyship — proliferated as racial justice demonstrations spread. Before that, straight allies joined the causes of LGBTQ oppression, discrimination and marginalization. 

“This year, we saw a lot of businesses and organizations very prominently, publicly, beginning efforts to promote diversity, equity and inclusion. Allyship is tied to that. In the classroom, there is a flashpoint around the term critical race theory. Allyship connects with this as well,” Kelly said. 

In addition, teachers, frontline workers and mothers who juggled jobs, home duties and child care in lockdown gained allies as the pandemic took hold last year. 

Without an entry for “allyship,” Kelly said the site saw a steep rise in lookups for “ally” in 2020 and large spikes in 2021. It was in the top 850 searches out of thousands and thousands of words this year. Dictionary.com broadened the definition of “ally” to include the more nuanced meaning. The terms “DEI” and “critical race theory” made their debuts as entries on the site with “allyship” this year. 

What it means to be an authentic ally has taken on fresh significance as buzz around the word has grown louder. One of the aspects of allyship, as it has emerged, is how badly it can go. 

Among the examples of how to use the word in a sentence cited by Merriam-Webster is this one written by Native activist Hallie Sebastian: “Poor allyship is speaking over marginalized people by taking credit and receiving recognition for arguments that the unprivileged have been making for their entire lives.” 

As global diversity, equity and inclusion executive Sheree Atcheson wrote in Forbes, allyship is a “lifelong process of building relationships based on trust, consistency and accountability with marginalized individuals and/or groups of people.” It’s not, she said, “self-defined — work and efforts must be recognized by those you are seeking to ally with.” 

Allyship should be an “opportunity to grow and learn about ourselves, whilst building confidence in others,” Atcheson added. 

Among the earliest evidence of the word “allyship,” in its original sense of “alliance,” is the 1849, two-volume work, “The Lord of the Manor, or, Lights and Shades of Country Life” by British novelist Thomas Hall: “Under these considerations, it is possible, he might have heard of Miss Clough’s allyship with the Lady Bourgoin.” 

Kelly did some additional digging into the history of allyship in its social justice sense. While the Oxford English Dictionary dates that use of the word to the 1970s, Kelly found a text, “The Allies of the Negro” by Albert W. Hamilton, published in 1943. It discusses extensively the potential allies of Black people in the struggle for racial equality: 

“What some white liberals are beginning to realize is that they better begin to seek the Negro as an ally,” he wrote. “The new way of life sought by the liberal will be a sham without the racial equality the Negro seeks. And the inclusion of the Negro in the day-to-day work, in the organization, the leadership and the rallying of the support necessary to win a better world, can only be done on the basis of equality.” 

On the other side of allyship, Kelly said, “is a feeling of division, of polarization. That was Jan. 6.” Allyship, he said, became a powerful prism in terms of the dichotomy at a chaotic cultural time during the last two years. 

Other dictionary companies in the word of the year game focused on the pandemic and its fallout for their picks. Oxford Languages, which oversees the Oxford English Dictionary, went for “vax” and Merriam-Webster chose “vaccine.” The Glasgow, Scotland-based Collins Dictionary, meanwhile, plucked “NFT,” the digital tokens that sell for millions. 

While Merriam-Webster relies solely on site search data to choose a word of the year, Dictionary.com takes a broader approach. It scours search engines, a broad range of text and taps into cultural influences to choose its word of the year.
