Scientists have identified a novel method to eliminate cancer cells by using aminocyanine molecules. These molecules, commonly used&nbsp;as synthetic dyes in bioimaging, show a remarkable capability to break apart cancer cell membranes when stimulated by near-infrared light, according to ScienceAlert.

Chemist James Tour from Rice University, who spoke to ScienceAlert,&nbsp;describes this&nbsp;technique as a "whole new generation of molecular machines" – aptly named molecular jackhammers.

In comparison to their predecessors, Feringa-type motors, these molecular jackhammers demonstrate over a million times faster mechanical motion. Moreover, they can be activated with near-infrared light instead of visible light.

The use of near-infrared light holds significant importance, as it facilitates deeper penetration into the body.

This breakthrough could potentially revolutionise the treatment of cancers in bones and organs, eliminating the need for invasive surgeries.

Scientists find new method which can destroy 99% of cancer cells, eliminate need for invasive surgeries

Australian researchers have invented a snake-like soft robot, designed to 3D print living cells from the inside of patients’ bodies. This development may soon eliminate the need for invasive surgeries to transplant 3D printed tissues and treatments, reported Freethink.&nbsp;

<h2>What are 3D bioprinters?</h2>

Similar to conventional 3D printers, 3D bioprinters build three-dimensional objects by layering ink. The only distinction is that they employ bioinks that contain&nbsp;living cells in them.

Researchers are using 3D bioprinters to produce ear implants for children who were born with birth abnormalities, stem cell patches to treat&nbsp;babies' hearts, and cartilage for reconstructive rhinoplasty.

3D bioprinting makes it seamless to create tissues in precisely the shape and size required. Considering a patients’ own cells can be used in the ink, the risk of rejection is lowered.

However, there is still a need for invasive implantation surgeries, which bioprinting cannot yet replace.

"Current 3D bioprinting techniques need the creation of biomaterials outside the body, and implanting those into a human would often require big open-field surgical surgery, which increases the risk of infection," said Thanh Nho Do, a biomedical engineer at UNSW Sydney who spoke to Freethink.&nbsp;

<h2>How do 3D bioprinters function?</h2>

Aside from printing bioinks, the soft robot can function as an endoscope, electric scalpel, and water dispenser. Researchers have tested these functions in an artificial colon and a pig’s intestine and kidney.&nbsp;

Before considering human trials, scientists will have to conduct in vivo testing on animals. If everything goes as planned, they anticipate that the bot will be ready for clinical use in five&nbsp;to seven&nbsp;years.

Once put into the colon, the robot may remove a difficult-to-reach tumour and then 3D bioprint material to promote healing on-site. If the robot passes development, clinicians may be able to use it to treat colorectal cancer, which is the second most common cause of cancer deaths, reported Freethink.&nbsp;

3D bioprinting in healthcare: This technology can eliminate the need for invasive surgeries

A law to criminalise "virginity repair" surgery, known as hymenoplasty, has been introduced by the British government.

Under an amendment to the health care bill added on Monday, any procedure that attempts to reconstruct the hymen will be illegal no matter if the individual undergoing the surgery consents or not.

A growing number of clinics, private hospitals, and pharmacies offer the controversial surgery promising the restoration of virginity - with a large number of girls and young women coerced into the procedure.&nbsp;

Also read |&nbsp;<a href="https://www.wionews.com/science/extra-money-with-parents-changes-babies-brains-says-a-landmark-study-447588" hreflang="en">Extra money with parents changes babies' brains, says a landmark study</a>

The purpose of this procedure is to make a girl or woman bleed when she next has sexual contact by creating a fake hymen using scar tissue.

Since the government committed to criminalising virginity testing last July, campaigners, including doctors and midwives, had called for the surgery to be outlawed.

It is considered a form of violence against women and girls to engage in either of these practices.

The ban will provide vital protection to girls under family pressure, according to one British survivor of "honour" based abuse who was harassed by her parents for months into having the surgery.

Hymenoplasty can never be justified on medical grounds, says &nbsp;Dr Edward Morris, president of the Royal College of Obstetricians and Gynaecologists.

He said that they have been campaigning for the introduction of a ban on both virginity testing and hymenoplasty alongside women's health and rights organisations, as both are inextricably linked with violence against women and girls.

Neither of these practices have a place in the medical world and should never be performed, he said adding that any time they learn that someone is performing these procedures, they will inform the General Medical Council so that appropriate action can be taken.

Morris went on to say that women deserve to be in charge of their own sexuality and reproductive health.

The executive director of the Iranian and Kurdish Women's Rights Organisation, Diana Nammi, said that every woman and girl who undergoes this invasive surgery do so under extreme duress, either direct or indirect. This is generally seen as a way to present the girl as a 'virgin', and oftentimes it is done to facilitate a forced marriage arranged by the family.

Approximately half of the time, hymenoplasty does not make the woman or girl bleed after having intercourse, which leaves her extremely vulnerable to 'honour'-based abuse or even 'honour' killing.

Consultations with experts led the government to come to the decision to ban hymenoplasty.

The Royal College of Obstetricians and Gynaecologists (RCOG) applauded this move. In a tweet, the organisation said that they are pleased to see that the Government of United Kingdom "has tabled an amendment to the Health and Care Bill to ban hymenoplasty alongside virginity testing."

They added that, they "will continue to work closely with the Government to ensure there is guidance, support and education for healthcare professionals on how to safeguard women as the ban comes into force."
