Modern-day slavery: an explainer
Photograph: Mario Tama/Getty
What is modern-day slavery?
About 150 years after most countries banned slavery –
Brazil was the last to abolish its participation in the transatlantic
slave trade, in 1888 – millions of men, women and children are
still enslaved. Contemporary slavery takes many forms, from
women forced into prostitution, to child slavery in agriculture
supply chains or whole families working for nothing to pay
off generational debts. Slavery thrives on every continent and
in almost every country. Forced labour, people trafficking,
debt bondage and child marriage are all forms of modern-day
slavery that affect the world’s most vulnerable people.
How is slavery defined?
Slavery is prohibited under the 1948 Universal Declaration
of Human Rights, which states: “No one shall be held in slavery
or servitude: slavery and the slave trade shall be prohibited in
all their forms.”
Definitions of modern-day slavery are mainly taken
from the 1956 UN supplementary convention, which says:
“debt bondage, serfdom, forced marriage and the delivery
of a child for the exploitation of that child are all slavery-like
practices and require criminalisation and abolishment”. The
1930 Forced Labour Convention defines forced labour as “all
work or service which is exacted from any person under the
menace of any penalty and for which the said person has
not offered himself voluntarily”. As contemporary systems of
slavery have evolved, new definitions, including trafficking and
distinguishing child slavery from child labour, have developed.
How many people are enslaved across the world?
Due to its illegality, data on modern-day slavery is difficult
to collate. The UN’s International Labour Organisation (ILO)
estimates that about 21 million people are in forced labour
at any point in time. The ILO says this estimate includes
trafficking and other forms of modern slavery. The only
exceptions are trafficking for organ removal, forced marriage
and adoption, unless the last two practices result in forced
labour. The ILO calculates that 90% of the 21 million are
exploited by individuals or companies, while 10% are forced
to work by the state, rebel military groups, or in prisons under
conditions that violate ILO standards. Sexual exploitation
accounts for 22% of slaves.

BACTÉRIA DE HOSPITAL FICA RESISTENTE
AO ÁLCOOL PARA LIMPEZA DAS MÃOS
Uma espécie bacteriana multirresistente, causadora de infecções hospitalares, está se tornando cada vez mais tolerante ao álcool usado para lavagem das mãos. A conclusão foi obtida a partir de amostras colhidas em dois hospitais australianos. A análise do material sugere que a espécie Enterococcus faecium está se adaptando a uma das ferramentas mais baratas e populares empregadas no combate a infecções em instituições de saúde. As infecções por E. faecium aumentaram, apesar do uso de desinfetantes à base de álcool, e atualmente representam uma das principais causas de infecções em hospitais.

SWEDISH CROWN JEWELS: SPEEDBOAT THIEVES STEAL PRICELESS TREASURES
Police in Sweden have launched a manhunt after thieves swiped some of the country’s crown jewels from a cathedral and escaped by speedboat. Two priceless crowns and an orb belonging to a 17th century king and queen were taken at around midday on Tuesday in Strängnäs, near Stockholm. Witnesses said they saw two men running from the cathedral, which was open to the public and hosting a lunch fair. They were seen motoring off into Lake Malaren, and have not been seen since.

HOW TO SPLIT THE CHECK WITHOUT THE ACCUSATIONS AND AWKWARDNESS
The stresses and frustrations of check-splitting are not exclusive to 20-somethings, but they seem to hit this subset of diners harder, and with more frequency, than other groups. Everyone, it seems, has a story of dining out in their 20s and getting stuck with the tab. The best way to handle these difficult splits is to notify your server ahead of time – just tell your server that you want individual checks.

A CENSUS QUESTION THAT COULD
CHANGE HOW POWER IS DIVIDED IN AMERICA
‘Is this person a citizen?’ The answer could mean less representation for populous states and big cities.
A citizenship question on the 2020 census has already drawn challenges from states that fear an undercount of immigrants and a loss of federal funds. But demographers say there could be even deeper consequences. The question could generate the data necessary to redefine how political power is apportioned in America.

Avoiding Aggressive Driving
The amount of aggressive driving is increasing on our roads. Some of the signs of an aggressive driver include a person who changes lanes abruptly to pass a slower driver, a driver who tailgates in an attempt to get another driver to speed up, and a driver who curses at other drivers. They put themselves and others at risk on the roads. A variety of studies have revealed certain traits common in aggressive drivers. If a person is ever pursued by an aggressive driver, he or she should ask someone in the car to call 911 or drive to a nearby police station. […] Finally, people who engage in aggressive driving behaviors take the chance of injuring or killing themselves and other drivers.

Student on Homesickness
When the homesickness hits, I usually get lazy and tired and just feel like going home and sleeping. I miss the safety of my family and the comfort of home, but most of all I miss my mother and just being able to talk to her whenever I want.
The homesickness usually hits when I feel out of place, or when I hear a song, or see something that reminds me of them. Usually, when I Skype them, it makes me feel worse because I can see them and talk to them, but I can't be with them.

The President is Missing
By Bill Clinton and James Patterson
When Tom Wolfe noted that “the problem with fiction” is that “it has to be plausible,” he may have had efforts
like this one in mind. Bill Clinton and James Patterson’s ambitious and wildly readable new novel, “The
President Is Missing,” arches more closely toward plausibility in its geopolitical subplots — threats against
the Saudi king, malicious Russian meddling in world affairs — than its main story line of a president who
ditches his handlers and goes rogue from the White House, convinced he is the only one who can foil a huge
cyberterror plot.
The book opens with a charged scene in which President Jonathan Duncan is participating in a mock
hearing to prepare for a congressional inquiry investigating the botched attempt to capture a terrorist. When
the president loses his temper, he vindicates the advisers who have cautioned him not to appear before the
actual committee. It’s a satisfying outcome for the former senior staffer in me — but unrealistic, considering
the picture of the president that unfolds on the subsequent pages.

In a letter to federal lawmakers, the tech giant insisted that iPhones do not listen to what users are saying

"iPhone doesn't listen to consumers except to recognize the clear, unambiguous audio trigger 'Hey Siri,'"

BRAZIL: JUDGE SHUTS BORDER TO VENEZUELAN
MIGRANTS FLEEING HUNGER AND HARDSHIP
Judge says entry of immigrants suspended until
conditions for ‘humanitarian reception’ are created –
activists called it ‘absurd’
A judge in Brazil has blocked Venezuelans from entering the
border state of Roraima as local authorities harden their stance
against the flood of migrants fleeing hunger and hardship in their
home country.
Judge Helder Barreto said he had suspended the entry of
Venezuelan immigrants until the conditions for a “humanitarian
reception” are created but activists working with migrants
attacked it as “absurd”.
Sister Telma Lage from the non-profit Migration and Human
Rights Institute, which helps vulnerable migrants in Roraima’s
capital Boa Vista, said the judge had overstepped his authority. “[Venezuelans] are entering Brazil and seeking refuge
because of the vulnerable situation they find themselves in,” she
said. “What we fear is the lack of options for those near to the
border.”
Since 2015, more than 56,000 Venezuelans have sought
refuge or residency in Brazil amid continuing political turmoil and
economic collapse in their home country. […]
But the flood of migrants has severely stretched health and
education services in the poor state of Roraima.

Pluto should be reclassified as a planet, experts say
The reason Pluto lost its planet status is not valid, according
to new research from the University of Central Florida in
Orlando. In 2006, the International Astronomical Union (IAU), a
global group of astronomy experts, established a definition of a
planet that required it to "clear" its orbit, or in other words, be the
largest gravitational force in its orbit. […]
Metzger, who is lead author on the study, reviewed scientific
literature from the past 200 years and found only one publication
-- from 1802 -- that used the clearing-orbit requirement to
classify planets, and it was based on since-disproven reasoning.
"It's a sloppy definition," Metzger said of the IAU's definition.
"They didn't say what they meant by clearing their orbit. If you
take that literally, then there are no planets, because no planet
clears its orbit." […]
Metzger said that the definition of a planet should be based
on its intrinsic properties, rather than ones that can change, such
as the dynamics of a planet's orbit. "Dynamics are not constant,
they are constantly changing," Metzger said. "So, they are not
the fundamental description of a body, they are just the
occupation of a body at a current era."
Instead, Metzger recommends classifying a planet based on
if it is large enough that its gravity allows it to become spherical
in shape. "And that's not just an arbitrary definition, Metzger
said. "It turns out this is an important milestone in the evolution
of a planetary body, because apparently when it happens, it
initiates active geology in the body."
