A major measles alert has been issued for two Australian states.

An urgent measles warning has been issued for two states after a toddler arrived in Australia from Vietnam with the infectious and deadly disease.

The South Australian government issued a warning after being notified of a three-year-old infected with measles travelling from Vietnam on Singapore Airlines flight SQ279, landing in Adelaide about 8.45am on Tuesday January 14.

Over the week, the toddler visited a number of places, including Kmart and Coles supermarket in Ingle Farm Shopping Centre on Wednesday January 15 before attending the Women’s and Children’s Hospital on Friday January 17.

Medical breakthroughs often change lives, but some redefine what’s possible for the future of healthcare. This historic achievement brings hope to millions around the world.

Discover the story of how one doctor’s groundbreaking work is reshaping what we know about hearing loss and recovery.

Imagine living in a world of perpetual silence—where the laughter of loved ones and the melody of a favorite song are mere concepts, never experienced. For millions across the globe, this silence is a daily reality caused by hearing loss. Yet, a breakthrough in medical science has rewritten the possibilities, turning silence into sound. At the center of this transformation stands Dr. Mashudu Tshifularo, a South African surgeon whose revolutionary use of 3D-printed implants has achieved what was once deemed impossible: curing deafness.

Research into stem cells has paid off as 68-year-old Paul Edmonds remains effectively cured of both HIV and leukemia following treatment that included a breakthrough stem cell transplant in 2019. Now, five years after the treatment, Edmonds continues to live his life free of HIV and leukemia.

This makes Edmonds one of only five people in the world who have achieved full remission of HIV. Further, his 31 years of living with the virus also means he had it the longest out of the five in remission. It’s a striking accomplishment that he has remained in remission for so long and showcases just how effective these kinds of treatments can be.

Stem cell transplants aren’t a new idea, either. What particularly makes this treatment so effective and intriguing, though, is that the transplant donor had a rare genetic mutation called homozygous CCR5 delta 32. This mutation makes people immune to most types of HIV.

A blog webpage written by entrepreneur Matt Krisiloff which offers helpful advice to scientific founders of biotechnology companies on how to fundraise and manage relations with investors.

“Because of examples of great success in the broader technology world, we’re seeing the emergence of what I’d call a more ‘Silicon Valley’ mindset in biotech investing. This approach prizes technology development at the core of the company’s DNA and – drawing from examples in tech such as Microsoft and Meta and in biotech such as Regeneron and Genentech – recognizes that technical founders who can grow into business leaders often build more innovative and ultimately more successful companies. This shift has opened up new avenues for fundraising that founders should understand and look towards”

At this point in my career across the biotech-related projects I’ve run, I’ve personally raised about $100 million. In some ways this feels like a lot, but given the scope of biotech and hard tech projects I care most about, it’s really just a drop in the bucket. From these experiences though, I’ve learned some things that I believe can help other founders navigate fundraising, and want to share them – especially for newer founders working on interesting technologies that may be approaching fundraising for the first time.

Scientists have built an artificial motor capable of mimicking the natural mechanisms that power life.

The finding, from The University of Manchester and the University of Strasbourg, published in the journal Nature, provides new insights into the fundamental processes that drive life at the molecular level and could open doors for applications in medicine, energy storage, and nanotechnology.

Professor David Leigh, lead researcher from The University of Manchester, said: Biology uses chemically powered molecular machines for every biological process, such as transporting chemicals around the cell, information processing or reproduction.

New research shows somatic mutations drive epigenetic changes tied to aging. This discovery reshapes our understanding of aging and challenges current anti-aging strategies.

Summary: A new study has uncovered a direct link between somatic mutations and epigenetic modifications, challenging established views on aging. Researchers found that random genetic mutations drive predictable changes in DNA methylation, offering new insights into the relationship between mutation accumulation and epigenetic clocks.

This suggests that epigenetic changes may track, rather than cause, aging, making it harder to reverse aging than previously thought. These findings redefine our understanding of aging at the molecular level and hold significant implications for future anti-aging therapies.

Scientists at deCODE genetics/Amgen have constructed a complete map of how human DNA is mixed as it is passed down during reproduction. The map marks a major step in the understanding of genetic diversity and its impact on health and fertility. It continues 25 years of research at deCODE genetics into how new diversity is generated in the human genome, and its relationship to health and disease.

The new map, appearing today in the online edition of Nature, is the first to incorporate shorter-scale shuffling, (non crossover) of grandparental DNA, which is difficult to detect due to the high DNA sequence similarity. The map also identifies areas of DNA that are devoid of major reshuffling, likely to protect critical genetic functions or prevent chromosomal problems. This insight offers a clearer picture of why some pregnancies fail and how the genome balances diversity with stability.

While this shuffling, known as , is essential for genetic diversity, errors in the process can lead to serious reproductive issues. These failures can result in genetic errors that prevent pregnancies from continuing, helping to explain why infertility affects around one in ten couples worldwide. Understanding this process offers new hope for improving fertility treatments and diagnosing pregnancy complications.

Scientists in the laboratory of Navdeep Chandel, Ph.D., the David W. Cugell, MD, Professor of Medicine in the Division of Pulmonary and Critical Care, have discovered how mitochondria influence the body’s immune response through modulating specific cell signaling pathways, according to a study published in Science Advances.

The findings highlight the potential of targeting specifically in immune cells to treat a range of inflammation-related diseases.

“Therapies aimed at improving mitochondrial activity could benefit inflammatory diseases such as , sepsis, and chronic infections by enhancing the immune system’s ability to regulate inflammation,” said Chandel, also a professor of Biochemistry and Molecular Genetics and a member of the Robert H. Lurie Comprehensive Cancer Center of Northwestern University.

When you press your fingernails together, do you see a tiny diamond-shaped window of light?

If you can’t see this ‘diamond gap’, you could have finger clubbing, which can be a sign of lung cancer. Finger clubbing is seen in 35% of people with non-small cell lung cancer (NSCLC), and in 4% of those with small cell lung cancer.

Finger clubbing is when the ends of your fingers swell up, and it happens in stages. First, the base of the nail becomes soft and the skin next to the nail bed becomes shiny. Next, the nails begin to curve more than normal when looked at from the side. Finally, the ends of the fingers may get larger and swell; it’s thought to be caused by fluid collecting in the soft tissues of the fingers.

Researchers leverage their understanding of molecular motors to improve nanoscale.

The term “nanoscale” refers to dimensions that are measured in nanometers (nm), with one nanometer equaling one-billionth of a meter. This scale encompasses sizes from approximately 1 to 100 nanometers, where unique physical, chemical, and biological properties emerge that are not present in bulk materials. At the nanoscale, materials exhibit phenomena such as quantum effects and increased surface area to volume ratios, which can significantly alter their optical, electrical, and magnetic behaviors. These characteristics make nanoscale materials highly valuable for a wide range of applications, including electronics, medicine, and materials science.
