A man has had a microchip implanted in his brain to help him overcome his addiction to pain medication.
With a history of overdoses, Gerod Buckhalter has struggled for more than decade with addiction to opioids and benzodiazepine for more than a decade.
But the 33-year-old has now been implanted with a Deep Brain Simulation (DBS) chip. Placed in the addiction and reward centre, it will send signals designed to limit cravings.
The technology that has so far proved useful to Parkinson’s disease sufferers in reducing tremors and it is thought that if successful in Mr Buckhalter and three other patients due to undergo the surgery, it could help to stem the tide of the US opioid epidemic.
The implant works in a similar way to a pacemaker, producing electronic pulses to stimulate the body.
1/20 Jackdaws can identify ‘dangerous’ humans
Jackdaws can identify “dangerous” humans from listening to each other’s warning calls, scientists say.
The highly social birds will also remember that person if they come near their nests again, according to researchers from the University of Exeter.
In the study, a person unknown to the wild jackdaws approached their nest. At the same time scientists played a recording of a warning call (threatening) or “contact calls” (non-threatening). The next time jackdaws saw this same person, the birds that had previously heard the warning call were defensive and returned to their nests more than twice as quickly on average.

2/20 Turtle embryos influence sex by shaking
The sex of the turtle is determined by the temperatures at which they are incubated. Warm temperatures favour females.
But by wiggling around the egg, embryos can find the “Goldilocks Zone” which means they are able to shield themselves against extreme thermal conditions and produce a balanced sex ratio, according to the new study published in Current Biology journal

African elephant poaching rates have dropped by 60 per cent in six years, an international study has found.
It is thought the decline could be associated with the ivory trade ban introduced in China in 2017.

Scientists have identified a four-legged creature with webbed feet to be an ancestor of the whale. Fossils unearthed in Peru have led scientists to conclude that the enormous creatures that traverse the planet’s oceans today are descended from small hoofed ancestors that lived in south Asia 50 million years ago

Dr Sidney Tamm of the Marine Biological Laboratory could not initially find any trace of an anus on the species. However, as the animal gets full, a pore opens up to dispose of waste

The Ledumahadi Mafube roamed around 200 million years ago in what is now South Africa. Recently discovered by a team of international scientists, it was the largest land animal of its time, weighing 12 tons and standing at 13 feet. In Sesotho, the South African language of the region in which the dinosaur was discovered, its name means “a giant thunderclap at dawn”

Scientists have witnessed the birth of a planet for the first time ever.
This spectacular image from the SPHERE instrument on ESO’s Very Large Telescope is the first clear image of a planet caught in the very act of formation around the dwarf star PDS 70. The planet stands clearly out, visible as a bright point to the right of the center of the image, which is blacked out by the coronagraph mask used to block the blinding light of the central star.

It has already been approved for application in cases of dystonia, epilepsy, and obsessive-compulsive disorder and the team at the West Virginia University Rockefeller Neuroscience Institute (RNI) who performed the operation, said they hoped it will also help to limit the urges associated with opiate addiction.
“Addiction is a brain disease involving the reward centres in the brain, and we need to explore new technologies, such as the use of DBS, to help those severely impacted by opioid use disorder,” said Dr Ali Rezai, the principal investigator leading the trial.
The first phase of the trial will see four patients undergo the surgery – all having failed to find sufficient support across a range of medical alternatives.
West Virginia has the highest age-adjusted rate of drug overdose deaths involving opioids in the US.
In 2017, drug overdose deaths involving opioids in West Virginia occurred at a rate of 49.6 deaths per 100,000 persons, according to the National Institute on Drug Abuse.
Dr James Berry, interim chair of the West Virginia University Department of Behavioral Medicine and Psychiatry and director of Addiction Services at RNI, added: “Despite our best efforts using current, evidence-based treatment modalities, there exist a number of patients who simply don’t respond. Some of these patients remain at very high risk for ongoing catastrophic health problems and even death.
“DBS could prove to be a valuable tool in our fight to keep people alive and well.”
