Boston Dynamics robot dog already knows how to shepherd sheep and control crops

A promotional video from Boston Dynamics has shown the potential of his robotic dog, Spot, to perform in the agricultural industry due to software from the robotic company Rocos, which is collaborating with Boston Dynamics to find ways to remotely control these robots, according to Business Wire.

The importance of Spot to farmers could translate into the robot monitoring the fields throughout the day, controlling crop growth or fruit maturation—all remotely—sciencealert ScienceAlertsays.

“Our customers are increasing their human workforce to automate physical processes that are often boring, dirty or dangerous,” explained Rocos CEO David Inggs..

One of Spot’s particular benefits is his agility: the robotic dog is able to traverse all kinds of terrain, something impossible for a robot on wheels. He is also known for his ability to rise again if he stumbles and falls.

One of the robot’s last exploits was the patrol of Singapore’s Bishan-AngMo Kio  Park, to inform residents by loudspeaker about the need to maintain the two-metre social estrangement. 

Diabetic retinopathy

The retina is the layer of the bottom of the eye that receives the luminous stimuli and perceives the images that will be sent to our brain. As in other chronic complications of diabetes mellitus, the presence of elevated blood glucose levels for many years causes alterations in the blood vessels of the retina that cause damage to this important eye tissue.

These vascular alterations make it difficult to supply oxygen to the retina, in which microneurysms, bleeding, as well as lipid and protein leakage from within damaged capillaries occur. This occurs primarily when diabetes is not properly controlled and is called diabetic retinopathy.

These changes are progressive and the lack of oxygenation of the retina stimulates the growth of more vessels that try to fill the deficit of blood supply. The appearance of these new vessels (a phase called proliferating diabetic retinopathy) can cause irreversible damage to the retina.

On the other hand, damage to the capillaries of the central part of the retina, the macula, can cause a leak of fluid into the retinal tissue (diabetic macular oedema) that leads to significant decrease in the patient’s vision.

Therefore, the key to the management of diabetic retinopathy is an early diagnosis, since treatment is effective in the early stages, and significant complications can be prevented. For this reason, periodic reviews are critical.

What are the usual symptoms?

Changes in diabetic retinopathy do not usually initially affect the central portion of the retina (the macula) and therefore do not result in a decrease in visual acuity, going unnoticed by the patient.

Conversely, in cases where macular oedema develops, the patient experiences a significant decrease in vision as well as distortion of images.

Diabetic retinopathy can evolve over years without being detected by its carrier, and even present at the time of diabetes diagnosis. That’s why specialized regulated follow-up is the only way to detect and treat your complications early.

The most common symptoms are:

Asymptomatic in early stages.

Decreased visual acuity.

Distortion of images.


¿Qué debe saber sobre la diabetes y la nutrición?

El páncreas es un órgano del cuerpo que produce una hormona llamada insulina. La insulina es el ayudante, o la “clave” que permite el azúcar, o glucosa, en las células del cuerpo, donde se almacena o se utiliza para la energía.

La diabetes es una enfermedad del páncreas. Con la diabetes tipo 1, el cuerpo no produce insulina. Con la diabetes tipo 2, el cuerpo no produce suficiente insulina ni usa insulina adecuadamente, también llamada resistencia a la insulina.

Los alimentos que comemos o bebemos se descomponen en un simple azúcar llamado glucosa. La glucosa proporciona la energía que su cuerpo necesita para las actividades diarias. Sin insulina, la glucosa no puede entrar en las células del cuerpo para su uso como energía. Cuando la glucosa no puede entrar en las células, permanece en la sangre. Demasiada glucosa en la sangre se llama “azúcar en la sangre alto” o diabetes. El A1C es una prueba que mide el nivel promedio de glucosa en sangre de una persona en los últimos dos a tres meses. El objetivo es tener un nivel por debajo del 7%.

¿Cuáles son algunos objetivos para una alimentación saludable?

Coma comidas y refrigerios a horas regulares todos los días. No se salte las comidas.

Coma alimentos con carbohidratos en cada comida y refrigerio, pero mantenga las porciones pequeñas para controlar el azúcar en la sangre.

Lea las etiquetas de los alimentos y conozca el tamaño de las porciones para contar los carbohidratos.

Elige alimentos ricos en fibra como panes integrales, cereales, pasta, arroz integral, frutas y verduras. Estos alimentos se digieren más lentamente, lo que ayuda a controlar el azúcar en la sangre.

Coma de dos a tres porciones (tamaño de porción 2-3 onzas) de alimentos proteicos por día.

Coma una variedad de alimentos para obtener todos los nutrientes que necesita.

Coma alimentos con menos azúcar y grasa.

Beba bebidas sin azúcar y sin calorías.

Bajar de peso si tiene sin sobrepeso reduciendo el tamaño de las porciones.

Planifique 30 minutos de ejercicio aeróbico de intensidad moderada a vigorosa al menos cinco días a la semana, junto con dos a tres sesiones de entrenamiento de resistencia al peso. Siempre consulte a su médico antes de comenzar una rutina de ejercicios.

¿Qué debes saber sobre diabetes y carbohidratos?

10 guidelines for managing stress during confinement

Avoid over information

The time we spend listening to or watching the news, conversational topics related to coronavirus, or the tireless avalanche of information through social media contributes to increasing fears. Therefore, we must limit the time spent talking and receiving information, choosing official sources of information and limiting our use of technologies  as well as television to find moments of disconnection and thus take care of ourselves emotionally, thus reducing our degree of discomfort.

Set up routines

We must set a schedule to work, eat, perform some sport at home as well as, to allocate  free time to share with family from home or with friends through social networks or videoconference. It is important to be able to maintain routines despite the situation, whether we live alone or as a family, the schedules will help us to adapt better to the situation.

Maintaining social contacts

Sverding some of our time talking to family and friends either over the phone or through social media makes the feeling of loneliness less. Sharing moments, taking an interest in the health of our loved ones, and chatting in a relaxed way about topics unrelated to Covid-19 brings a sense of unity and mutual support.


Through physical exercise we secrete endorphins, a hormone that contributes to improving our mood and our overall well-being.  Therefore, it is important that every day we spend part of our time to physical activity. Today, we have countless online videos and tutorials to be able to spend our time on that exercise that we like and motivate. It can be a fun activity to do with family or even by video call with friends.

Healthy diet

Having good eating habits in times of confinement is also important. Sometimes staying at home for a long time can lead to more eating between hours. Planning a weekly menu will help avoid emotional hunger.

Hygiene and personal care

Hygiene habits should not be neglected by the fact that you do not have to leave home and go to work or meet friends. It’s easy to fall into the temptation to go in your pajamas or clothes to be home by not having to go to work or meet friends. Aseasm helps normalize an unusual situation.

Boost creativity

Beyond the time spent on telework, there are many free hours that we have to spend at home without the possibility of going out on the street. Boredom is a fantastic ally of creativity. Dedicate a few hours of the day to let the imagination fly by making crafts, writing, drawing, playing an instrument, playing… will make us discover a part of us that in our usual routines often has no place for lack of time.

Propose some challenges

Why not, take advantage of the confinement situation to pose some challenges or tasks that we always think we don’t have time to do. We all have a small list of to-dos or activities that our busy day-to-day keeps us from doing. Start a book, order, fix something from home… will help you feel that time passes faster and we are making the most of the time.

Sense of humor

Laughing helps you relax and  therefore our anxiety levels will be reduced. Using our sense of humor helps you cope with our stress. A sense of humor can help us relativize the situation and temporarily disconnect from the concern around Covid-19.

Ask for help

If despite the proposed indications you feel that you find it difficult to manage your discomfort. At ITAE Psychology we have a team of psychologists who are experts in stress and anxiety management who can help you.

Cognitive performance, a key factor in lupus

A significant percentage of lupus patients suffer cognitive dysfunction without having had neurological damage associated with the disease. This is a factor to consider in the approach and follow-up.

The main neurological damage associated with systemic lupus erythematosus are strokes, seizures and psychotic outbreaks. However, between 20 and 40 percent of patients with rheumatological disease develop cognitive dysfunction once these causes are ruled out. A team of researchers from the Gregorio Marañón Hospital in Madrid has selected a group of patients to determine the impact of cognitive dysfunction on these patients without apparent neurological injuries.

The conclusions of the work have been published in the journal European  Neurology. Among the authors of this study are the head of Rheumatology Service, Luis Carreño, the rheumatologist Javier López-Longo, the neurologist Javier Olazarán, the neuropsychologist Isabel Cruz and the specialist in Nuclear Medicine  Angel  Bittini,all from the center of Madrid.

Javier Olazarán has stated that “we selected 31 women with lupus from the hospital’s Rheumatology office who had no major brain damage associated with the disease. We performed a battery of neuropsychological tests collecting data on attention, executive functions, memory, visospatial area, language, reasoning and processing speed; from this information we established a few cut-off points for a control group of women of similar characteristics without relevant neurological disease.”

The criteria chosen to determine which women with lupus had cognitive dysfunction were to perform below the fifth percentile in at least two of the tests performed.

López-Longo points out that selected patients were under 50 years old to avoid the influence on age-linked cognitive decline.

“To determine what cognitive dysfunction was due to, we conducted a simple correlation study with various biological markers, such as time of evolution, tissue damage, disease activity, various types of antibodies, and drugs administered; we found that it was not clearly associated with any of these variables, but women with cognitive dysfunction did have a clearly lower working situation than those who did not have the impairment,” Olazaran says.

The impact on the socioeconomic situation of cognitive dysfunction due to non-neurological causes is an element to consider in the approach to lupus: “Cognitive performance should be taken into account in the study and treatment of these patients, even if they have never had significant neurological manifestations,” concludes the neurologist.

Babys born by surrogacy that have not been claimed in Ukraine

The image strikes: dozens of children are in their cots, in a hotel room in Ukraine, waiting for their parents to take them.

But they’re not children whose parents are in the next room.

They are babies born by surrogacy (or surrogate bellies) and who due to the cancellation of flights around the world by the pandemic of the covid-19, their adoptive parents, residing abroad, have not been able to travel to the European country to claim them.

“My son was born weeks ago but I haven’t been able to meet him yet”: the Argentinian couple who can’t go to Ukraine to pick up their baby

“We came to this because our borders are closed and the (Ukrainian) foreign minister decided not to allow foreigners to enter Ukraine, not even those who have a baby born here,” Denis Herman, a medical centre lawyer, told BBC.

The practice of surrogacy or surrogacy is criticized by several sectors that indicate that this is a form of economic exploitation of women. In countries such as India, Nepal or Thailand it has been banned.

In Ukraine this practice is legal and staff of the UN Commission on Human Rights noted that the place is in perfect condition to provide care to minors pending their parents’ pick-up.

A nurse cares for a guide dog for weeks along with its owner admitted to his hospital amid covid-19

A Vietnam War veteran and his labrador ended up in a Nevada hospital in March and after the coronavirus facility closed, they were unable to receive visitors.

American nurse Barbara Borbeck  has for weeks cared for a guide dog that ran out of care at  Southern  Hills Hospital in Las Vegas, Nevada, where he works and was quarantined by the coronavirus crisis.

Vietnam War veteran Joe Tasbywas admitted for lung disease and heart arrhythmia in mid-March accompanied by his lazarillo dog,  Cupid. At the time, he did not think that his stay could last much longer than “two or three days,” he confessed to CBS News.

Although he had visitors at first and his daughter would help him walk Cupid  and feed him, after the hospital closed all visits suddenly ceased and then when Barbara gave her a hand. The nurse walked the dog near the hospital every time it was her turn and made sure she didn’t miss food and ‘chuches’ for nearly three weeks.

Cupid came to be very fond of him and expected the arrival of his assistant at the door every day. Barbara even once drove 40 minutes before her shift to go to a store where there was  Cupid’s special meal she hadn’t been able to find in nine nearby stores.

“That she took the time to find a particular type of a particular brand of food was extraordinary,” Tasby told CBS News. “How do you really express gratitude when someone steps forward and does so much for you at a time when it would be really difficult, almost impossible for me to do it?” he asked.

During his time at CupidHospital, for his part, he also helped the staff and took turns performing the work of a therapy dog in different departments. Barbara explained that by the coronavirus closure the therapy dogs could no longer frequent the site, and the labrador turned out to be the only dog available.

Joe and Cupid  were discharged on April 1 after spending 21 days in hospital. The nurse followed them to the car from the main entrance. “It’s lucky to meet someone who’s in the right place, at the right time, doing the right thing. And that’s Barbara,”  tasbysaid, who finds no way to thank him and show him how much he appreciates everything he did for the two of them.

Miami Millionaires

It is known that accessing a good quality of life in Miami has its cost; and high. But, the natural advantages offered by the paradise city makes it year after year one of the cities selected by millionaires from all over the world, to buy luxury residences and access the comfortable and extravagant life of Miamense.

A report made annually by the real state company that specializes in selling luxury residences  Christie’s  International stipulated that in 2015 more than 45% of luxury property sales in Miami were made by foreign millionaires.

Miami ranks nationally best-selling, in second place behind New York City. Within this statistic are properties that are quoted above one million dollars.

In the 1980s the city is located in the center of tourism service worldwide. Over the next decade, celebrities such as Madonna, Julio Iglesias, Gloria and Emilio Estefan, Susana Gimenéz,Sylvester Stallone, Ricky Martin, have been residents of the city. At that time the favorite places were  Indian  GreekAvenue,  Star  Island, North Bay Road and  Bal  Harbour..

Today, extremely luxury real estate developments, are sold in pre-construction  almost entirely a year of being launched. That is why it is common to see in Miami so many stars from all professional fields, and the advantage, is to be in the city of the sun without bodyguards, custodians, only enjoying the good life and the misvagances miamenses.

MusiciansRicky Martin, Shakira and Lenny  Kravitz  have their waterfront mansions in the city, located on North Bay Road. Actor Matt Damon, Nicolas Cage and actress Susana Giménez have her mansion in  Venetian  Isles very close to Miami Beach. The phone diva after moving in 2013 from Fisher Isles, one of the most expensive islands to live in the world, decided to buy a beautiful residence in a unique place.

Of all that way, the driver is surrounded by Hollywood actors, NBA players and Latino artists. In this area, the houses are quoted from $4 million to 7 million, almost all have private moorings and paradisiacal landscapes.

A luxury apartment in the exclusive Asia building (East style, with a privileged view of BiscayneBay), is worth $2.5 million, on average. Brickell Key Island also has restricted access, each building has private security, according to BAE.

According to a survey by Forbes magazine, Miami is listed as the hemispheric center for global investment. In addition, the South Florida city is shaping up as the city of the future as its development, profitability and sustainability of businesses over the past few years, have positioned it as the best destination for investment.

Most investors are Latinos and Europeans who decide to move their assets in the city of Miami, because for every dollar they invest in a business, it produces medium- and long-term profits. Another feature that this niche has in the market, is that the investor comes with cash, immediately reviving the local market.

The effects of diabetes on the heart

he functions of the heart in a human organism make it absolutely indispensable for life, because it is still the most important muscle in the body. For this reason, it is essential to carry out care for the pumping machine, which is also exposed to severe metabolic diseases, such as diabetes, a disorder that affects millions of people internationally, some 300 million  people according to estimates, although this figure could rise to 435 million by 2035 according to medical forecasts.

The reason diabetes is one of the main threats of the heart system responds to the disease being able to produce or respond optimally to the hormone insulin, essential for converting glucose, so-called blood sugar, into energy. The energy of the food consumed, therefore, cannot be used by the body, so that cells are damaged by this absence of energy transfer. Glucose is not assimilated by cells, the amount of glucose in the blood rises and hyperglycemia and diabetes are generated.

The lower circulation, the higher blood pressure

The problems that diabetes creates in the proper functioning of the heart begin with high rates of so-called bad cholesterol and few levels of good cholesterol, at the same time as triglycerides  – a type of fat found in the blood – also increase. This combination hardens the arteries in a process called atherosclerosis, which is forged when fats, cholesterol and other harmful substances accumulate in arterial channels and block blood flow.

Since it cannot pass ordinaryly, the heart, lungs and kidneys do not receive the same amount of blood and their functioning is not conventionally performed, in addition to increasing blood pressure. This extra amount of blood glucose causes excessive thickness and increases the chances of clots more easily occurring and smaller blood vessels weakening. These clots are semi-solid masses of blood whose appearance can alter circulatory flow.

In addition to these harmful effects, this clotting can come from arterial damage that causes your plaque to shed and cause these obstacles to the passage of blood, to the point that if it occurs in one of the arteries of the heart a heart has a heart attack. In case other arteries are blocked throughout the entire anatomy, this harmful phenomenon is called embolism.

Diabetes not only directly impacts heart function, but also decreases your body’s ability to fight infections or pathogens and heal wounds. This inefficiency means that infections are longer lasting and wounds take longer to heal.

Those affected by diabetes

Although the 300 million diabetics worldwide do not meet uniform standards, medical studies on this disease have shown that there is an inherited genetic predisposition, as it can be passed down from generation to generation. However, people who suffer from obesity are more susceptible to this disorder, as there are certain fats that inhibit the already developed interaction between insulin and glucose.

According to a study by the Spanish Heart Foundation on the relationship between this muscle and diabetes, people suffering from the disease should follow guidelines of fundamental dietary routines to best alleviate the effects of diabetes. With regard to sweeteners, sugar or honey are not recommended because they raise the blood glucose level and its high fattening caloric level; with saccharin, meanwhile, moderate consumption is allowed and never more than 10-12 tablets daily.

Alcoholic beverages are also not well received, since their high volume of calories adds to the emergence of triglycerides,thus being especially prohibited for those with high cholesterol records. Soft drinks, with a high presence of inadequate sweeteners among their ingredients, are also not positive. The same goes for tobacco, one of the great enemies of heart health. As for salt, although it does not significantly influence the effects of diabetes, unless you are a hypertensive person. In older age, a low-sodium diet is improving for the cardiovascular system.

The characteristics of diabetes and its effects on the heart mean that the recommended instructions to alleviate its effects and prevent serious problems go through a healthy diet and with a reduced presence of sugars and fats, as well as include to the routine a few patterns of physical exercise in search of weight loss, since obesity is a risk factor for diabetics. Regular assistance to medical specialists to monitor the evolution of the body, cholesterol and blood circulation is also essential to work day by day against this disease and maintain a firm health.
