This service allows to identify where the international space station is. An alert is received when it is visible from the user’s location so that the user can identify it. You can also see the Chinese stations Tiangong 1 and Tiangong 2. The remains of the first could fall to Earth at any time and, in fact, there is an alert for the damage it could cause. Available for iOS and Android.

3. Space Images

The app was developed by the Jet Propulsion Laboratory, a center responsible for developing unmanned spacecraft for NASA. It has informative images and data about planets, moons, galaxies and more. The photos can be downloaded to the device.

4. Exoplanet

It is an interactive catalog of all known exoplanets. The application was developed by a professional astronomer who is responsible for keeping it updated. Every time a finding occurs, a notification is received. It integrates a map of augmented reality, that is, it is enough to point the phone at the sky to identify the location of an exoplanet. It is available for iOS.

5. Star map

It allows to identify stars and constellations in a similar way to Star Map. It is also possible to recognize and learn about the different planets of the solar system and other galaxies, as well as see satellites and other celestial objects. It is available for iOS and Android.

7. Star Tracker

This tool is a guide to explore space. Like some of the other apps mentioned above, Star Tracker is used to using the cell phone as a kind of “digital telescope.” Just point the phone’s camera at the sky to see and learn about different constellations.

Baby is born the world’s first automated vitrified egg

The world’s first baby born from an automated vitrified egg, preserved by cryopreservation, came to the world in a clinic in Barcelona, Spain.

The baby was born on September 29 completely healthy, with 2.2 kilograms of weight and 46 centimeters of height, by normal delivery after 37 weeks of gestation, informed the Reproductive Medicine Service of the clinic Dexeus Mujer, whose experts managed to make this advance assisted reproduction.

Glazing is an ultra-fast cryopreservation system that reduces the time and risk of ice crystal formation, and could only be done manually up to now.

“This birth confirms the viability of this new technology, which has been on the market for only a year and is currently only incorporated by some hospitals,” explained the head of the Biology Section of the Reproductive Medicine Service of the Barcelona clinic, Montse Boada. and assisted reproduction clinics from around the world. ”

The head of the cryopreservation laboratory at the clinic, Miquel Solé, explained that “vitrification is an ultra-fast cryopreservation system that reduces the time and risk of ice crystal formation, offering a high survival rate after devitrification. of oocytes, currently around 85%. ”

The first time successful embryo cryopreservation occurred in 1983, but the introduction of oocyte cryopreservation into the clinical application only occurred in 2005.

So far, the vitrification process has always been done manually, so that the person in charge of preparing the samples and performing the different steps of vitrification until their storage in liquid nitrogen at -196ºC should be a specialist embryologist.

“It’s a job in which you have to be very strict and experienced to have a good result,” said Solé.

The novelty of this new system, called GAVI, is that it allows the exposure of the biological material, in this case, the oocytes, to the cryoprotectants to occur in an automated way and in a hermetically sealed device, avoiding the direct contact of the oocytes with the liquid nitrogen.

“The automation of the GAVI system reduces the possible risk of contamination and minimizes the small variations that may occur in manual protocols.” Reproductive Medicine of Dexeus Woman.


Denver Public Schools to Protect Immigrant Students in US

Within superintendent schools, 56% of the 91,000 students are Hispanic. Another 20% belong to other minorities.

The Denver Public Schools Superintendent announced Friday that the city’s institutions will be “safe and accepting places” for all students, including illegal immigrants.

“In light of recent local and national immigration and refugee events, the Denver Public Schools Superintendent has decided to respond to the fear and uncertainty that many of our students and families are feeling,” said Lisa Flores, a member of the board.

In addition to the idea of ​​building a wall on the Mexican border, US President Donald Trump has begun operations in several regions of the country and has threatened to reduce the transfer of resources from cities that refuse to cooperate with immigration authorities.

The Denver schools resolution emphasizes that the activities of federal immigration agents at school institutions or buses interfere with the constitutional rights of students, including the right not to be subjected to unreasonable detention or magazines, and to free public education.

“There is great strength and solidarity in being together as a community to protect the rights of our students,” said Flores.

Within superintendent schools, 56% of the 91,000 students are Hispanic. Another 20% belong to other minorities.

Since the November 2016 election, Denver’s United Parents and Young People organization has collected more than 1,000 signatures to call for schools to be declared “sanctuaries” for students and families who are at risk of deportation.

Therefore, the Denver Public Schools Superintendency will not collect information about the students’ immigration status and will not pass it on to the federal government without a court order, according to the resolution.

Increased exposure to sunlight influences high incidence of skin cancer

According to a specialist, people are now more exposed to the sun, less clothing, sun-less, and getting sunnier

More exposure to sunlight influences skin cancer to kill one person every 52 minutes in the world, said dermatologist Rodrigo Roldán Marín, head of the Oncodermatology Clinic at the Faculty of Medicine of the National Autonomous University of Mexico (UNAM) ).

The specialist explained that we are all susceptible to suffer from this disease. “We must stop believing that it is an exclusive subject of blue-eyed blond individuals. It affects black and dark people, and yet little is known about it, “he said in a statement.

According to Marin, every year more cases of skin cancer than breast, prostate, lung, and colon are recorded together, and this is influenced by a cultural change.

“Today we have unusual practices in past centuries that expose us to one of the most important environmental carcinogens: sunlight,” he said.

The expert said that today people are exposed more to the sun, with less clothing, without sunscreen and increasingly earlier.

In Mexico, he said, new cases of skin cancer are detected each year; however, there is a lack of prevention culture and this is because the disease is minimized.

“The sun causes progressive and accumulated damage and the rays received today will have repercussions two, three or four decades later, so we should promote protection habits among children and teach them how to use sunscreen.”

Marin explained that it is necessary to take into account that basal cell carcinoma is the most common cancer among humans, one in five will develop it, “and if we add that the skin is our largest organ, it is inexplicable not to take care enough”.

The expert said that much research still needs to be done about it because although the characteristics of skin cancer in white people are well known, it is necessary to sink in what happens to other characteristics.

“For example, Australia is the country with the highest incidence of melanoma because it is in the geographic region most exposed to the sun; so an Australian can generate between three and four melanomas in his life and survive, “he said.

However, Marin detailed that if a Mexican develops a melanoma, he is very likely to die due to this.

“This has to do with genetics, and although we’re not sure why, it appears that darker, though more protected, skin develops cancer in more aggressive variants when it contracts.”

The specialist said that general practitioners should be instructed to use the dermatoscope, a pocket-sized microscope, in order to detect this disease in a timely fashion.

“This would not only significantly increase the diagnostic accuracy of skin cancer variants (such as melanoma, basal cell or squamous cell carcinomas), but it would improve our reference and counter-reference system by detecting tumors in preterm infants,” he concluded.
