BELO HORIZONTE, Brazil: Three decades ago, Brazilian researchers began studying a curious side effect from banana spider bites: the toxin left victims with priapism, a painful and persistent erection.
The scientists were inspired to develop a synthetic molecule using some properties of the spider’s poison to create a gel to treat erectile dysfunction, which is now undergoing promising clinical trials.
Covered in thick brown hair, and with a maximum size of up to 15 centimeters (six inches), the arachnid is one of the most poisonous in the world.
It is found in several South American countries, and was nicknamed for its common presence in banana plantations, but it is also called the “wandering spider” or “armed spider.”
In the southeastern Brazilian state of Minas Gerais, it is found in rural areas as well as urban centers.
At the Ezequiel Dias Foundation (FUNED), a medical research center in the state’s capital Belo Horizonte, a biologist delicately grabs one of the spiders with a pair of tweezers and stimulates its fangs to get a few drops of venom.
FUNED then sends the venom to the Federal University of Minas Gerais (UFMG) which has been researching which component could be replicated to treat erectile dysfunction, which affects tens of millions of men around the world.
“The venom is only used to learn the properties of the molecule” which causes the priapism in bite victims, said Maria Elena de Lima, a UFMG researcher.
Brazilian biotech company Biozeus has bought the patent for the molecule.
The company wants to sell it in an ointment, which would be rubbed on the male organ when required, resulting in an erection in a few minutes, said de Lima.
The molecule triggers the release of nitric oxide, which is essential for an erection as it increases blood circulation and allows blood vessels to widen.
De Lima said the research could be especially useful in the fight against cancer, as men suffering prostate cancer often refuse a procedure to remove the prostate because it can damage nerves and lead to erectile dysfunction.
After the first phase of clinical trials was approved by Brazil’s Anvisa regulatory agency, the medication has now moved into the second of three phases prior to being approved for sale.
De Lima said the discovery of a potential erectile dysfunction treatment was a message “not to destroy animals, even poisonous ones, because there is a real library of molecules that are still unknown.”

59-kilogram monster fish catches eyes at Nigerian fishing festival
- Over the decades, the festival grew into one of Nigeria’s biggest cultural events, drawing international visitors, before insecurity and funding shortages reduced it to an occasional celebration
ARGUNGU: Local fisherman Abubakar Usman’s 59-kilogram monster catch was the major highlight of the UNESCO-listed Argungu fishing festival, which returned after a six-year hiatus because of the insecurity in northwestern Nigeria’s Kebbi state.
Thousands of people, including a handful of women and children, defied the blistering 39-degree heat to take part. Fishermen from Nigeria’s West African neighbors Niger, Chad, and Togo also came to compete.
The fishing festival was first staged in 1934 by the then traditional ruler of Argungu, Mohammed Sama. It was held to mark an end to a century-old history of hostility and distrust between his people and the region’s most powerful ruler, the Sultan of Sokoto, then Hassan Dan-Mu’azu.

Over the decades, the festival grew into one of Nigeria’s biggest cultural events, drawing international visitors, before insecurity and funding shortages reduced it to an occasional celebration. The last full edition was held six years ago, say organizers.
On Saturday, fishermen floated on brown, round gourds as they hunted for the biggest catch in Matan Fada river, using only their hands and nets in the river’s murky waters.
Thousands of spectators lined the riverbank cheering loudly.
For the Emir of Argungu, Al-Hajji Samaila Mohammed Mera, hosting the festival this year was a victory of some sort.
Parts of Kebbi state have seen sporadic militant attacks in recent years, with analysts blaming the Lakurawa terror group for the deadly violence.
“I came back to have a fuller experience,” said Adeniyi Olugbemii, 56, who is attending the festival a second time from neighboring Sokoto state.
Outside the arena that sits on the edge of the Matan Fada, chants, drumbeats, and cultural displays added to the atmosphere, highlighting the heritage that has turned Argungu into a global tourism draw.
Rukaya Ismaila, 23, said she had traveled from Kogi state, some 850 kilometers away, to attend the festival for the first time.
“The famous Argungu that we’ve been told about since primary school,” she said.
“It is worth all the excitement,” she added, praising the way the competing fishermen helped each other out.
Days of activities preceded the fishing competition, including a motor rally from Nigeria’s capital city, Abuja, a Durbar procession, and a variety of cultural events.
Abubakar Usman’s hefty catch earned him two new saloon cars and 1-million-naira cash prize (about $739).
Hundreds of much smaller catches ended up at a makeshift market set up on the adjoining streets to the arena.
The event was overshadowed by a prominent political campaign for the re-election of President Tinubu and Kebbi Gov. Mohammed Nasir Idris.
Billboards and posters of both men lined the streets leading to the river arena.
Supporters in blue t-shirts emblazoned with their images drummed and danced, drawing crowds of their own, while songs eulogising the visiting president blared through speakers inside the main arena.
Earlier in the day, a false start around midday had forced the already anxious contestants to plunge into the river. They had defied the scorching sun to wait for the arrival of President Bola Tinubu.
The president arrived more than two hours later, after which the contest was restarted.
