In mammals, including humans, scar tissue forms after injury to the spinal cord as part of the healing process. In mammals, however, this has a serious drawback: the scar tissue cannot be penetrated by regrowing nerves. As a result, severed nerves cannot regenerate. In the case of spinal cord injury, this leads to permanent paralysis.

More than half our population (50.7%) are born with ovaries and will experience perimenopause in midlife. This occurs as hormone levels decrease and ovaries slow their release of eggs.

Australia is now into its next COVID wave. We’ve seen hints of this for a while. Case numbers and indicators of severe disease began rising in Victoria in August. But it has taken several months for a consistent pattern to emerge across Australia.

Surprisingly little is still known about autism and breastfeeding. A few years ago, we reviewed all of the research evidence and found limited information about the experiences of autistic parents—beyond highlighting that the sensory differences when breastfeeding could be very challenging for them. We also found that communication by health professionals didn’t always meet the needs of autistic parents.

SPEAKER of the National Assembly Nelly Mutti has driven some Members of Parliament to wade into uncharted waters as she has been reported to the Anti-Corruption Commission.

Removing a gene that manages stress within insulin-producing beta cells draws helpful attention from the immune system, protecting mice predisposed to type 1 diabetes from developing the disease, a new University of Wisconsin–Madison study shows.

Using air travel records and data on where local conditions make transmission more likely, Yale School of Public Health (YSPH) researchers have identified countries where outbreaks of an extensively drug-resistant form of typhoid fever are most likely to occur. The research, published in Nature Communications, could help prevent and control additional outbreaks.

Looking around us, we can see that people age at different rates. But what about inside? Do all cells age in the same way? And does the location of a cell in the organ make a difference to the aging process?

All cancer cells—even those within the same tumor—differ from each other and change over the course of a cancer disease. Scientists at Heidelberg University Hospital, the Medical Faculty in Heidelberg and the German Cancer Research Center discovered molecular changes in multiple myeloma that help individual cancer cells to survive therapy. The study was published in the journal Blood.

In a study published in the journal Circulation Research, researchers at the Centro Nacional de Investigaciones Cardiovasculares (CNIC) led by Dr. José Luis de la Pompa reveal the essential role of the protein neuregulin-1 (Nrg1) in the intricate transformation of the heart from its delicate primordial structure into a powerful pumping organ.
