The levels of greenhouse gases in the atmosphere, the main driver of climate change, have hit a new record high, the UN said Thursday, warning that the time to act was running out. Ahead of the COP 24 climate summit in Poland next month, top United Nations officials are again trying to raise the pressure on governments to meet the pledge of limiting warming to the less than two degrees Celsius, enshrined in the 2015 Paris accord.

Asthmabegins with an inflammation in the lungs. The airways inside the lungs swell up, obstructing the airflow, which impedes gas exchange in the lungs. Especially exhaling becomes difficult for patients. Carbon-dioxide-enriched air in the lungs can no longer be properly discharged. The patients feel difficulty in breathing while the stimulus — the desire to get fresh oxygen into the lungs — becomes stronger and stronger. However, when they inhale, they cannot ventilate the lungs properly because the stale air in the lungs has not been completely released yet. This leads to dyspnea, a vicious circle which the patients can only break out of through conscious and calm exhalation excercises. Graph: How asthma develops What to do in the event of an asthma attack? It s important to keep calm. The patient should sit upright and place their forearms on their thighs. When standing, they should adopt a broad-legged, forward-leaning "goalkeeper position." This helps them to use all the auxiliary breathing muscles in the shoulder, chest and back area.

Uncomfortable for your boss and uncomfortable for you, workplace feedback is often associated with the classic dread one experiences before a visit to the dentist. In the same way that staring numbly into the abyss of the dentist s ceiling while getting cavities filled is essential to the vitality of a pearly white smile, feedback is essential to the vitality of a successful career.

RTS,S is also limited because it s protective effect decreases considerably within four years. This is because the vaccine uses a single protein of the malaria pathogen Plasmodium falciparum (which occurs most frequently in Africa) to direct the immune system against the parasite. However, an immune reaction to only one protein of the pathogen also means that the immune system repeatedly allows intruders to invade and malaria gets through anyway. In addition to Plasmodium falciparum, there are other malaria pathogens against which the RTS,S vaccine does not work.

At the age of 20, many people still don t know exactly what they want to do with their lives. The same seems to apply to sexual orientation. This, at least, is a result of a survey of almost 7,000 American students. They were interviewed three times about their sexual preferences between 1995 and 2009: as teenagers, in their early twenties and in their late twenties. Especially for young women, the early twenties are a sexually dynamic time. In contrast to young men, out of whom 90 percent said that they were heterosexual, only two thirds of young women would place themselves in this category. Ten percent felt they were mostly heterosexual and 7.5 percent epressed a clear interest in both sexes.

How do you manage the trick of feeding school children better and at a lower cost? How do you count the number of mangoes on your farm so that you get a fair price? And what’s a clever-but-cheap way for a farmer to cut down his irrigation bill? Agriculture in sub-Saharan Africa may have the image of relentless toil and low productivity, but experts say new tech is changing the picture.

Infants less than a year old should not be exposed to electronic screens, the World Health Organization (WHO) said on Wednesday. Issuing its first such guidelines, the United Nations health agency said that older children, aged two to four, should be limited to one hour per day sedentary screen time. The guidelines also covered sleep and exercise. Among the findings were that: Infants under one should interact in floor-based play — or "tummy time" — for at least an hour each day and avoid all screens.

President Abdel Fattah al-Sisi delivered a speech on Saturday during the Belt and Road forum in the presence of the Chinese president and a number of heads of states and governments, stating that Egypt seeks to become a regional digital hub for data transmission between Asia, Europe and Africa, as it is one of countries with the highest number of maritime cables globally. Egypt seeks to attract more direct investments in this field, with the aim of maximizing economic exploitation and generating job opportunities offered by the digital economy, as bridging the digital divide between developed and developing countries, he said.

It might sound like a sci-fi fantasy, but scientists are determined that one day we ll be able to 3D-print vital organs, like the heart, kidney or liver, to use in transplants. Cardiovascular disease and stroke kill more people globally than anything else, according to the World Health Organization, and synthetic organs could help enormously in overcoming issues of organ shortage and the risks of patients bodies rejecting them.

Britain’s privacy regulator wants to stop kids from being able to “like” posts on Facebook and other social media sites as part of tough new rules it’s proposing to protect children’s online privacy. Under the draft rules, which were released for consultation on Monday , tech companies would not be allowed to use “nudge techniques” that encourage children to keep using a site.

Using an ultrasensitive scanning technique, researchers can detect signs of Alzheimer s disease in the tiny blood vessels at the back of the eye, according to a new report. Duke University researchers found that these small retinal blood vessels were altered in patients with Alzheimer s disease, but in not in those with mild cognitive impairment (MCI) or those with no signs of mental decline.

Is the dream of one global internet still alive? Increasingly, moves by governments to filter and restrict content are threatening to fragment the system created with the promise of connecting the world with a largely unified body of content. China for years has walled off some western services, and the fragmentation may be accelerating with regulations being imposed elsewhere, say analysts.

Compared with dogs, the human sense of smell is pathetic: The animals smell 10,000 to 100,000 times better than we do. They can sniff out not only drugs and explosives, but also cancer. However, in previous studies, the accuracy of the animals left something to be desired. There s a new US study out that claims an amazingly high hit rate. Three beagles are said to have identified 96.7 percent of lung cancer in blood samples. The dogs detected the healthy control in 97.5 percent of the cases. Only a fourth dog in the group, Snuggles, had no desire at all for the job.

For a long time it has been assumed that it is only a woman s age that matters when it comes to having children, as her fertility begins to decline in her 30s and 40s and she then reaches menopause in her 40s or 50s. However, research over the past few years has illuminated that a father s age matters, too, when it comes to both fertility and a child s development. A recent study in the journal Biological Psychiatryreaffirms the link between advanced paternal age and schizophrenia and reveals that specifically the risk of early-onset schizophrenia increases in the offspring of older fathers. This severe form of schizophrenia occurs before the age of 18 and is associated with more genetic abnormalities.
