The Bottom Line on Facebook Depression
[1] Facebook, the most popular social media platform, does
not make people more depressed on its own. Instead, what
the research shows is that Facebook – when used as a
surveillance device – leads to a greater risk of feelings of
[5] envy. And the more those feelings of envy increase, the more
likely it is for a person to start feeling depressed.
The key to stopping these feelings is to not use Facebook
primarily as a surveillance method to spy on your family and
friends’ lives. Instead, use it as a social network where you
[10] share your own information, photos and updates, as well as
consume other’s updates and shares.
Healthy use of Facebook will protect you against the
possibility of feeling more depressed after using it. It’s a
simple thing you can try for yourself – especially if you feel
[15] more envious after checking Facebook.

TEXTO:

All for one and one for all is what we all should be.
But instead we go and fight each other.
Now, that wasn’t meant to be.
You know, the sun is there to light the day.
[5] The night is lit by the moon.
If we don’t come together, my brother, it all can end

[very soon.

It’s your world now.
The future is plain to see.
(Sing it, yeah. Sing it, yeah, yeah, yeah.).
[10] Give love right now.
We need the harmony.

Antony’s lines from Act III, Scene 2 of Julius Caesar

[1] Friends, Romans, countrymen, lend me your ears;

I come to bury Caesar, not to praise him.

The evil that men do lives after them;

The good is often interred with their bones;

[5] So let it be with Caesar. The noble Brutus

Has told you Caesar was ambitious:

If it were so, it was a grievous fault,

And grievously has Caesar answered it.

Here, under leave of Brutus and the rest–

[10] For Brutus is an honourable man;

So are they all, all honourable men–

Come I to speak in Caesar’s funeral.

He was my friend, faithful and just to me:

But Brutus says he was ambitious;

[15] And Brutus is an honourable man.

He has brought many captives home to Rome

Whose ransoms did the general coffers fill:

Did this in Caesar seem ambitious?

When the poor have cried, Caesar has wept:

[20] Ambition should be made of sterner stuff:

Yet Brutus says he was ambitious;

And Brutus is an honourable man.

You all did see that on the Lupercal

I thrice presented him a kingly crown,

[25] Which he did thrice refuse: was this ambition?

Yet Brutus says he was ambitious;

And, sure, he is an honourable man.

I speak not to disprove what Brutus spoke,

But here I am to speak what I do know.

[30] You all did love him once, not without cause:

What cause withholds you then, to mourn for him?

O judgment! you are fled to brutish beasts,

And men have lost their reason. Bear with me;

My heart is in the coffin there with Caesar,

[35] And I must pause till it come back to me.

The Americas are Now Measles-Free

The Americas has become the first region in the world to be free of measles, following a 22-year vaccination drive against the disease which continues to infect tens of thousands of people globally, the Pan American Health Organization said on Tuesday.

The milestone was confirmed after no cases of the highly contagious disease originating in the Americas were recorded in at least three years, the PAHO said.

"This is truly a historic deed," said Carissa Etienne, director of the PAHO, which serves as the World Health Organization's (WHO) regional office for the Americas.

Globally, measles remains a leading cause of death among young children in the developing world. About 250,000 people were infected with measles last year, most in Africa and Asia, the PAHO said.

According to the WHO, the virus that can lead to deadly complications like diarrhea, dehydration, respiratory infection and encephalitis kills an estimated 314 people every day.

The last outbreak of measles that originated in the Americas occurred in Venezuela in 2002, PAHO said. But the region was only declared free of measles this year.

Justin Lessler, an epidemiology expert at the Johns Hopkins Bloomberg School of Public Health in Baltimore, said imported cases of measles - which remains widespread in other parts of the world - could still lead to small outbreaks in the Americas. "People still need to be vaccinated to maintain elimination," he said.

Before a separate, worldwide vaccination drive against measles began in the 1980s, the disease caused 2.6 million deaths a year worldwide - 12,000 of them in the Americas, according to PAHO.

Measles is the fifth vaccine-preventable disease to be eliminated in the Americas - after smallpox in 1971, poliomyelitis in 1994, and rubella and congenital rubella syndrome in 2015, the PAHO said.

Stretchable hydrogel can be used as a 'smart bandage' and delivery vehicle for medical devices.

Engineers at MIT have developed an elastic yet sturdy hydrogel material that can be used as flexible, biocompatible wound dressing and as a smart delivery method for drugs or medical devices.

The material was designed to be embedded with medicallyuseful electronics, such as conductive wires, semiconductor chips, LED lights, and temperature sensors, according to a study published online December 7, 2015 in the journal Advanced Materials.

Electronics coated in the hydrogel could be placed not only on the surface of the skin but also inside the body—such as implanted biocompatible glucose sensors or soft, compliant neural probes, the researchers wrote.

“Electronics are usually hard and dry, but the human body is soft and wet. These two systems have drastically different properties,” said lead investigator Xuanhe Zhao, Associate Professor in MIT’s Department of Mechanical Engineering.

Dr. Zhao explained, “If you want to put electronics in close contact with the human body for applications such as health care monitoring and drug delivery, it is highly desirable to make the electronic devices soft and stretchable to fit the environment of the human body. That’s the motivation for stretchable hydrogel electronics.”

Current hydrogels are often brittle and made of degradable biomaterials that don’t last long, he explained. So, his team designed a hydrogel that is not only as flexible as human soft tissues, but can bond strongly to non-porous surfaces such as gold, titanium, aluminum, silicon, glass, and ceramic.

Early dinosaur relative walked like a croc

One of the earliest relatives of dinosaurs had some features we associate today with crocodiles and alligators, a study suggests.

Many palaeontologists have wondered what the earliest dinosaur relatives looked like, as the fossil record in this time period is sparse. Some assumed they walked on two legs, looking a bit like miniature dinosaurs. But the newly described creature walked on four legs like a croc, the journal Nature reports.

The 2-3m (7-10ft) carnivorous animal, unearthed in southern Tanzania, lived some 245 million years ago during the Triassic Period. It pre-dated the earliest dinosaurs. Prof Paul Barrett, one of the authors on the new paper, said: “This is a little animal that we call Teleocrater. It’s not very big...it probably would have weighed about the same as the average family dog.”

Teleocrater rhadinus appeared just after a large group of animals known as archosaurs split into one branch that led to dinosaurs, and another branch that led to today’s alligators and crocodiles. Its anatomy combines features present in the last common ancestor of these groups, such as a crocodilian-like ankle joint, with some features considered characteristic of dinosaurs.

The first fossils belonging to Teleocrater were discovered in 1933 in Tanzania. They were studied at London’s Natural History Museum in the 1950s. But these specimens were missing crucial bones, such as the ankle. Therefore, scientists at the time could not tell whether they were more closely related to crocs or to dinosaurs.

The new specimens were uncovered in the East African country in 2015, resolving some of those outstanding questions. They show that it is one of the earliest members of the archosaur family tree and that it walked like a crocodilian.

Teleocrater, along with other dinosaur relatives, lived across a wide range of different regions, from Russia to India to Brazil. The team’s next steps are to return to southern Tanzania to look for more remains and missing pieces of the Teleocrater skeleton.
