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.

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.
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.
Planning to save for retirement might not be a priority. Luckily, you’ll have some help from Social Security. Different salaries can drastically raise or lower your Social Security benefits. Here’s how much you can expect, based on six different salaries. The average Social Security check in 2020 is $1,503. Figuring out how much you can expect every month when you retire depends on a few criteria. The size of your payment will be based on income from your working years, the year you were born and the age when you decide to start receiving benefits. Luckily, CNBC did the math for a wide range of salaries, and we can estimate your future benefits if you make between $30,000 and $100,000 per year. Remember: Social Security was not envisioned as your sole source of money for retirement, and the totals are always changing. Watch this video for a breakdown of how much you will get and how your monthly benefit will be calculated based on multiple different salaries.
Does your grandparent hold the secret to a happier New Year? Because Americans over 80 years old report feeling happier than any other age group, we asked them to share their wisdom as 2021 begins during a time of challenge and uncertainty. These elders include cannabis comedian Tommy Chong, a psychologist, a transgender burlesque performer, and a 90-year-old nudist who lets it all hang out. Self-Evident: A PBS American Portrait Miniseries seeks to answer the question: what does it really mean to be an American today? Join our hosts — Dr. Ali Mattu, a licensed therapist and clinical psychologist and YouTuber behind “The Psych Show,” as well as Danielle Bainbridge, Ph.D., historian and the writer/creator of PBS’s “The Origin of Everything” — as they explore the lives of real Americans, living during this unprecedented moment in time.
