Past river activity in northern Africa reveals multiple Sahara greenings

The analysis of sediment cores from the Mediterranean Sea combined with Earth system models tells the story of major environmental changes in North Africa over the last 160,000 years

Large parts of today’s Sahara Desert were green thousands of years ago. Prehistoric engravings of giraffes and crocodiles testify to this, as does a stone-age cave painting in the desert that even shows swimming humans. However, these illustrations only provide a rough picture of the living conditions. Recently, more detailed insights have been gained from sediment cores extracted from the Mediterranean Sea off the coast of Libya. An international research team examined these cores and discovered that the layers of the seafloor tell the story of major environmental changes in North Africa over the past 160,000 years.

An AI saw a cropped photo of AOC. It autocompleted her wearing a bikini.

Language-generation algorithms are known to embed racist and sexist ideas. They’re trained on the language of the internet, including the dark corners of Reddit and Twitter that may include hate speech and disinformation. Whatever harmful ideas are present in those forums get normalized as part of their learning.

Researchers have now demonstrated that the same can be true for image-generation algorithms. Feed one a photo of a man cropped right below his neck, and 43{0ab330907ab55d1d247a5e46cbfc213f668b37838ccb2fc637c3c0da5f4ad964} of the time, it will autocomplete him wearing a suit. Feed the same one a cropped photo of a woman, even a famous woman like US Representative Alexandria Ocasio-Cortez, and 53{0ab330907ab55d1d247a5e46cbfc213f668b37838ccb2fc637c3c0da5f4ad964} of the time, it will autocomplete her wearing a low-cut top or bikini. This has implications not just for image generation, but for all computer-vision applications, including video-based candidate assessment algorithms, facial recognition, and surveillance.

Okta SaaS report finds Office 365 wins the cloud — sort of

Each year Okta processes millions of SaaS logons via its authentication system. It kindly aggregates that data to find the most popular apps and publishes an annual report. This year it found that the most popular tool by far was Microsoft Office 365.

It’s worth noting that while app usage popularity varied by region, Office 365 was number one with a bullet across the board, whether globally or when the report broke it down by geographic area. That wasn’t true of any other product in this report, so Office 365 has extensive usage across the world (at least among companies that use Okta).

But as with everything cloud, it’s not a simple matter to say that because lots of people signed onto Office 365, Microsoft is the clear winner in a broader sense. In reality, the cloud is a complex marketplace, and just because people use one tool doesn’t … Read more

New ion trap to create the world’s most accurate mass spectrometer

Credit: Evgeny Nikolaev and Anton Lioznov/Skoltech

Mass spectrometers are widely used to analyze highly complex chemical and biological mixtures. Skoltech scientists have developed a new version of a mass spectrometer that uses rotation frequencies of ionized molecules in strong magnetic fields to measure masses with higher accuracy (FT ICR). The team has designed an ion trap that ensures the utmost resolving power in ultra-strong magnetic fields. The research was published in the journal Analytical Chemistry.

The ion trap is shaped like a cylinder made up of electrodes, with electric and magnetic fields generated inside. The exact masses of the test sample’s ions can be determined from their rotation frequencies. The electrodes must create a harmonized field of a particular shape such that the ions rotate predictably. A trap with such a field is called a Dynamically Harmonized Cell (DHC).

The DHC was invented in 2011 by Evgeny Nikolaev, a

Meet Smash Ventures, the low-flying outfit that has quietly funded Epic Games among others

 

When in 2018, Smash Ventures showed up as an investor in a $1.25 billion round for Epic Games — reportedly the largest ever investment in a video game company at the time — it was the first time many had heard of the investing outfit.

When the brand showed up again last summer in an even bigger round for Epic —  last August, the games giant announced $1.78 billion in fresh funding at a post-money equity valuation of $17.3 billion — a diner near Epic’s Cary, North Carolina headquarters that sells “smash waffles” started getting calls from reporters, says Eric Garland, who used to lead venture and growth deals for The Walt Disney Company after selling his company, BigChampagne, to Live Nation in 2011.

“Some reporters really turned over rocks,” he says.

Garland knows this, he says, because he cofounded Smash Ventures with Evan Richter, a former member of … Read more

For years, I’ve tried to work my way back into the middle class

 

Early this winter, I took a long walk in the Salt Lake City park in which I had been arrested for bathing in a river when I was homeless.

About 30 minutes into that walk, I stood across from the park’s granite meditation temple, thinking: Three and a half years ago, I slept under that building’s awning.

I can still feel how hard that temple’s cold stone floor was; I remember how people strolled by my bed of cardboard and clothes and stared with what struck me as a combination of concern, contempt, and pity. Now I see that these are also the lenses through which I have often judged my own progress in my new, not-yet-middle-class life.

These days, I often wonder: Am I really doing as well as I should be after all this time? How did I ever allow myself to fall so far? Trying to Read more

FGM safeguarding policies are alienating UK’s African diaspora communities

Credit: United Nations

AHEAD of tomorrow’s International Day of Zero Tolerance for Female Genital Mutilation, by the United Nations, FORWARD, the leading African women-led organisation working to end violence against women and girls, and the University of Huddersfield have published new research that documents how the stringent, targeted, FGM safeguarding measures introduced since the 2014 Girl Summit are causing distress and mistrust amongst African diaspora communities in Bristol, and potentially across the country.

The research reveals first-hand evidence documenting how FGM safeguarding policies are leaving families feeling racially profiled, criminalised and stigmatised. To access the full study report, please follow this link: https://www.forwarduk.org.uk/forward-publications/fgm-safeguarding-bristol-study/.

Over the latter half of the last decade, the UK government intensified its response to FGM, giving FGM a ‘special’ status within national safeguarding, going far beyond the UK’s regulatory approach to other forms of child abuse.

This includes the introduction of FGM Mandatory Reporting Duty, the

Predictive policing is still racist—whatever data it uses

It’s no secret that predictive policing tools are racially biased. A number of studies have shown that racist feedback loops can arise if algorithms are trained on police data, such as arrests. But new research shows that training predictive tools in a way claimed to lessen bias has little effect.

Arrest data biases predictive tools because police are known to arrest more people in Black and other minority neighborhoods, which leads algorithms to direct more policing to those areas, which leads to more arrests. The result is that predictive tools misallocate police patrols: some neighborhoods are unfairly designated crime hotspots; others are underpoliced.

In their defence, many developers of predictive policing tools say that they have started using victim reports to get a more accurate picture of crime rates across different neighborhoods. In theory victim reports should be less biased because they aren’t affected by police prejudice or … Read more
