How a doctor in Florida performed surgery on a patient in Africa
A doctor in Florida successfully performed a prostatectomy on a patient in Africa using transcontinental robotic telesurgery.
Dr. Vipul Patel, medical director of the Global Robotic Institute at Orlando's Advent Health, operated on Fernando da Silva, 67, who was diagnosed with prostate cancer in March.
The surgery, performed in June, was a success and marked the first patient in a human clinical trial approved by the Food and Drug Administration for this technology.
Patel used fibre optic cables to bridge the thousands of miles, noting no perceptible delay in control, with a surgical team present with the patient as a backup.
The doctor highlighted the enormous humanitarian implications, suggesting the technology could benefit underserved areas globally and rural communities in the U.S.

One study find say a daily dose of beetroot juice fit get a significant effect on blood pressure. Di study find say just a few weeks of eating some beets a day lead to a fall in average blood pressure of about 5 millimetres of mercury, if maintained, e dey enough to reduce di risk of stroke and heart attack by 10% . Studies don also find say beetroot fit get effect on blood pressure within a few hours of intake. Prof Andy Jones, Professor of Applied Physiology from di University of Exeter wey spend years investigating di effects of beetroot on sport performance explain how di nitrates inside beetroot improve dey improve di blood flow to our lungs and muscles, resulting in a faster delivery of oxygen. "Di potential dey for di muscle to dey receive more oxygen and to distribute dat oxygen within imsef more effectively because of di effects of nitric oxide", e tok.

Prof Peter Weissberg, medical director for di British Heart Foundation, wey bin fund di research, tok say: "e dey support current advice say make we all dey eat plenty of green vegetables. "But we need larger studies in patients to determine if nitrate-rich vegetables dey effective to lower blood pressure over di long term." Also, di nitrates dey water-soluble though, so you need dey careful wen you dey boiling beets. To boil your beets go allow nitrates to come out into di cooking liquid, so you no go get as many benefits.

Rare ducklings hatch at Chester Zoo
A group of rare ducklings have hatched at Chester Maccoa duck is one of Africa's rarest and most endangered duck the first time the species has ever been successfully bred at the say only around 5,000 of the ducks remain in the wild, with the latest surveys finding just 14 individuals in Kenya and fewer than 100 in Tanzania - prompting concern over the future of the conservationists say they hope the successful hatching will lead to more protection for the birds. Maccoa ducks are diving ducks often found in nutrient-rich wetland habitats, like freshwater wetlands and are known for their stiff tails and deep-blue species is listed as endangered on the International Union for the Conservation of Nature's (IUCN) Red List of Threatened degradation, water pollution and climate change have been blamed for the species decline. There are just twelve zoos in the world that look after Maccoa ducks. Andrew Owen, Head of Birds at Chester Zoo, said:"This success gives a real boost to the future of the species... These birds are facing rapid decline in the wild, so every hatchling really does count."
