Police are searching devices seized from a man accused of setting fire to a synagogue to find his motive for the alleged attack.

Angelo Loras, 34, faced Melbourne Magistrates Court today after being charged over the alleged firebombing at an East Melbourne synagogue.

The NSW man looked down for much of the short hearing where he appeared via video link from prison wearing a white T-shirt with a beard and long hair.

Loras has been charged with multiple offences over the fire at East Melbourne Hebrew Congregation on July 4, which allegedly forced a group of about 20 people inside the building to flee.

His charges include reckless conduct endangering life, criminal damage by fire and possession of a controlled weapon, police have said.

Loras' lawyer told the court today there were several issues defence disputed with prosecution, as he opposed release of a summary document.

"There is ongoing investigation of this matter, you'd hope by September that investigation has been complete," defence lawyer Ben Mcgrath said.

Magistrate Malcolm Thomas asked prosecutors if there was a chance the matter could go to trial before a jury in a higher court.

Police prosecutor Anthony Albore said that was "certainly a possibility" as he flagged two electronic devices seized by officers needed to be interrogated.

"Particularly if there is evidence obtained form those devices, that may establish a motive to this particular crime," he said.

"That may take this matter out of this honourable jurisdiction."

Loras will next face the court on September 12.

The synagogue fire is one of several recent alleged acts of anti-Semitism across Melbourne, including a protest incident at Israeli restaurant Miznon on July 5.

In December, fire tore through Adass Israel Synagogue in Ripponlea, in Melbourne's southeast.

A 20-year-old man was charged with car theft on July 17, which counter-terrorism police alleged was linked to that blaze.

However, no one has been charged with carrying out the Adass firebombing.

Police have launched new searches to locate the missing remains of 39-year-old Julian Story, who was allegedly murdered by his former reality television star partner at their home on South Australia's Eyre Peninsula.

Tamika Chesser, 34, remains in police custody at a mental health facility in Adelaide after officers were called to a fire at the yard of their Flinders Highway home in Port Lincoln on June 19.

Police allege the former Beauty and the Geek dismembered Story's body, leaving it without a head, two days before the fire.

A multi-agency search crew have been extensively scouring the Port Lincoln area for Story's head.

Today, Major Crime Investigation Branch Detective Superintendent Darren Fielke said new information and specialist equipment had helped identify several more sites to search in and around Port Lincoln.

"New search areas have been identified and by undertaking these renewed searches, we hope to find Julian's missing remains, which will give comfort to his family and allow them to peacefully lay him to rest," he said in a statement.

"Police have reviewed a significant amount of CCTV footage since the incident which has provided a number of investigational leads."

The sites will be searched over the coming days.

Late last month, police released vision of who they believe to be Chesser a few hours before the alleged murder.

The woman in the footage is seen walking with a dog.

Her sister previously told 9News that Chesser had been checked out of a mental health facility in Port Lincoln just weeks before the alleged murder, despite her family's pleas.

She said they had been concerned about her mental health for months. 

"It's my sister, but that's not who she is or the Tamika we know. That's not the Tamika anyone knows," she said.

A landmark Australian study may have found a treatment and cure for a virus that impacts 10 million people worldwide.

Human T-Cell leukaemia type 1 (HTLV-1) is a life-threatening virus that impacts the immune system and the blood cells involved in fighting off infection within the body.

Research on HTLV-1 has been sparse, but a study conducted by the Walter and Eliza Hall Institute of Medical Research (WEHI) and the Doherty Institute in Melbourne has found existing drugs used to treat HIV can also help suppress HTLV-1.

The study, which took place over 10 years, saw mice infected with human immune cells susceptible to HTLV-1 infections. 

However, when the mice were then treated with two well-known antiviral therapies – tenofovir and dolutegravir – the results showed the drugs were also able to significantly suppress HTLV-1.

The study also found the cells could be selectively killed when the mice were treated with these drugs.

Co-lead author and WEHI laboratory head Dr Marcel Doerflinger praised the development as a huge step in the right direction for finding a long-term treatment and cure to a highly prevalent disease.

"What's most exciting is that these antivirals are already in use for millions of HIV patients, meaning there's a direct path for the clinical translation of our findings," Doerflinger said.

"We won't have to start from scratch because we already know these drugs are safe and effective.

"And now we've shown that their use can very likely be extended to HTLV-1."

The study also found the cells could be selectively killed when the mice were treated with these drugs, further emphasising the potential for a cure to HTLV-1.

This is particularly important for First Nations communities in parts of Central Australia, who have been impacted by a particularly aggressive strain of the virus.

Professor Damian Purcell of the Doherty Institute said the study would help experts in fighting both HTLV-1 and other similar diseases.

"There is a real opportunity to prevent the transmission of HTLV-1 and end the diseases caused by these infections," Purcell said.

"Our research findings are a major leap forward in this."
