Biomarkers are measurable indicators of what’s happening in your body. They can be found in blood, other body fluids, organs, and tissues, and can be used to track healthy processes, disease progression, or even responses to a medication. Biomarkers are an important part of dementia research.

Science: Extreme Old Age Gene Quest, Gravitational ‘Glint’ Waves, Early Springs
The team explores a theory that suggests gravitational waves may be the thing that finally helps us detect dark matter – we just need to look for the ‘gravitational glint’.
Spring is rolling around earlier and earlier. The team examines a new study which shows that since the 1980s, the warming climate has brought the season forward by a month – which could have major ecological implications. They also discuss a study which looks at the impact of marine heatwaves on things like coral and fish populations.

Science Of Aging: Social Insects May Hold Secrets
Bees, termites, and ants can teach us a lot about cooperation, communication, and the skills that keep societies together. But these so-called social insects may also hold secrets that could reshape our understanding of human aging. Many social insects exhibit surprising aging characteristics that cause their life spans to shift depending on their roles.
Following the death of a queen Indian jumping ant, for example, workers fight for the right to transform into an egg-laying ant. Much is at stake: the life expectancy of an egg-layer is five times longer than that of a worker’s. Though fruit flies, mice, and nematodes currently dominate aging research, some scientists say social insects’ aging behaviors could help dissect aging mechanisms in humans. This video will take you deep into the catacombs—er, honeycombs—of insect aging.

Alzheimer’s Disease: ‘How It Starts & Progresses’
The first event in our Lab Notes online series features two researchers from our South Coast Network Centre talking about early brain changes in Alzheimer’s. Dr Karen Marshall shares her work studying how waste disposal and recycling systems in nerve cells cause damage in Alzheimer’s disease, and whether there could be ways to rescue cells from this. Dr Mariana Vargas-Caballero speaks about her research into brain cell connections and how they are affected in Alzheimer’s. The event is chaired by Dr Katy Stubbs from Alzheimer’s Research UK, and also features a Q&A session.
Medical Views: ‘Macular Degeneration Research’
Macular degeneration is a leading cause of visual impairment in people over 65 and can lead to blindness. One in three people will eventually suffer some degree of macular degeneration, which is caused by abnormal blood vessels under the retina, the light-sensitive part of the eye. We treat both the more common “dry” as well as the more dangerous “wet” forms of macular degeneration. While there is currently no cure for this disease, we offer the latest treatments to reduce the risk of vision loss and blindness. These include anti-VEGF drugs—which attack proteins that create the abnormal blood vessels that cause macular degeneration—and photodynamic therapy, in which patients ingest medication that is then activated with a laser.
