Scientists have regrown amputated frogs legs, paving the way for regeneration in humans

Scientists at Tufts University and Harvard University's Wyss Institute have regrown amputated limbs. In a study published in Science Advances, the researchers showed how they used a chemical cocktail to induce limb growth in frogs.

The scientists first amputated the leg of an adult female African clawed frog, and then coated the stump with a special five-drug cocktail. They let the wounds soak in the solution for the next 24 hours. Then, over the next year and a half, the adult frogs regrew a functional leglike structure with nerves, muscles, bones, and toelike projections.

The frogs’ regenerated limbs were functional, but not perfect. Their new appendages lacked toenails and some webbing, but the frogs were able to use their new leg to swim.

Just a handful of animals are able to naturally replace lost limbs, including some salamanders, starfish, and axolotls.







Scientists hopeful that one day humans can regenerate lost limbs

The regrowth of an almost fully functional leg in many of the treated frogs was a hopeful result for the scientists.







"The fact that it required only a brief exposure to the drugs to set in motion a months-long regeneration process suggests that frogs and perhaps other animals may have dormant regenerative capabilities that can be triggered into action," Nirosha Murugan, a research affiliate at the Allen Discovery Center at Tufts said.

"We'll be testing how this treatment could apply to mammals next," said corresponding author Michael Levin, director of the Allen Discovery Center at Tufts.

The research team hopes that the study "brought us a step closer to the goal of regenerative medicine." They plan to test the treatment on mammals next.

This commentator thinks MCI ad should not have featured poor Malays

May 12, 2022 | 🚀 Fathership
A Hari Raya advertisement by the Ministry of Communications and Information (MCI) was 'cancelled' by certain netizens online for depicting lower income Malays according to reality.

"Message for Syawal", a two-and-a-half-minute video published last month (Apr 30) captures moments in the life of a low-income Malay family living in a rental flat.

Storyline

The video, which is peppered with Malay proverbs, shows the family moving out of their rental flat to a new home several years later where they celebrate Hari Raya.

The father of the family works as a mover while the mother is a housewife.

Their young son, Syawal, skips school to earn extra income for his family before a teacher flags his absence from school to his parents.

The mother in the video later decides to return to work to alleviate her family’s financial difficulties while the father gets a new job.

Why some netizens are outraged

The video sparked backlash online, with some viewers saying that it contained stereotypes about the Malay community.

The stereotypes:
  • The father works as a mover - commonly perceived to be a low-income job
  • The mother is jobless
  • The son plays truant
  • The family lives in a rental flat for low-income earners

Commentator implied that poor Malays shouldn't be portrayed in public to prevent stereotypes

A video commentary by The Homeground Asia went further by criticizing how the video propagates the narrative that Malays are poor and lazy, and that the ministry should have created a video that is more relatable to both the less fortunate and the more affluent Malays.

Adi Rahman, one of the interviewees in the video went further by making sweeping assumptions that the ministry lacked cultural intelligence and did not consult the community on the narrative.

Ironically, in talking about inclusivity, Adi implied that the realities of poor Malays should not be shown in public.

For example, his rationale suggested that the video contained characters (the mover, jobless mother and the son who skips school) that contribute to the problem of other races seeing the Malays in a stereotypical and reductive light.

In other words, show the good stuff but not the reality.

Adi even accused the ministry for not consulting the Malays in the vetting of the video narrative.

His accusations were without merit, however, when the Ministry said in a statement (Apr 30) that Malay-Muslim viewers - presumably a focus group - had seen the video prior to its release, and perceived the story to be heart-warming, although some expressed reservations.

Stereotyping or masking reality?

The ministry said last month (Apr 30) the video was meant to show "a family’s journey of resilience in facing challenging circumstances and how mutual support and encouragement could nurture the process”.

Other netizens felt it was an overreaction and that low-income families shouldn't be dehumanized in a way that they are removed from the conversation. They felt that the video was a call-to-action for those from the underprivileged to strive for a better life through hard work and seeking help that's already available.

The only missed opportunity in the MCI video was perhaps the suggestion that Malays in low income families living in a rental flat could not celebrate Hari Raya unless they get a flat on their own.

But of course, like Homeground Asia, that is also a sweeping assumption.
