Parasite-infected ants have discovered the secret to living a longer life
Arianna Schneier writes about the longevity-altering effects of a tapeworm that infects ants. A three-year study revealed that tapeworm-infected, compared to uninfected, worker ants exhibited increased lifespans similar to that of queen ants. The study, conducted by Susanne Foitzik from Johannes Gutenberg University with various collaborators, focused on Temnothorax nylanderi found in Central Europe. The…

A New Piece in the Puzzle of Human Evolution
Sophie Teall writes about how the discovery of an archaic human population in Israel suggests a more complex evolutionary history than previously thought. As modern humans (Homo sapiens), we are the only members of the group Homo still walking the earth. It is easy to forget that several human lineages have called this planet home.…

Novel findings in the biology of depression: Is now the time to update the 60-year-old serotonin theory?
Serotonin is a hormone produced by nerve cells from tryptophan, an amino acid which enters our body through our diet. Foods such as nuts, cheese and red meat are rich in tryptophan and hence, consumption of these products correlates with higher serotonin levels. Serotonin systemically affects our body, from motor functions to emotions. Serotonin in…

How brain cells repair their DNA reveals “hot spots” of aging and disease
The brain is the organ responsible for our personality, consciousness and ability to process our surrounding environment. It, quite simply, makes us who we are. Unfortunately, as we age it is not solely our body that begins to fail us, but our mind responsible for our identity also deteriorates. However, the process behind this deterioration…

Supermassive black hole: Andromeda’s and the Milky Way’s black holes will collide
Our nearest galaxy, Andromeda or M31, lies 2.537 million light years (or 2.4 x 1019 km) away. However, scientists have agreed that it is on a collision course for our own Galaxy, the Milky Way, with an estimated speed of 116 km/s. Most studies agree that this will happen between 4 to 5 billion years…

Concern for the Climate Endures Through the COVID-19 Pandemic
COVD-19 may be cutting coverage on the climate crisis, but that doesn’t mean people have stopped caring about the climate. 2020 began with wildfires raging across Australia in an unusually intense bushfire season. Driven by drought, high temperatures and lightning, this was a stark reminder of how climate change contributes to the threat of natural…

Robotic Touch: Artificial skin brings robots closer to ‘touching’ human lives
When we anticipate the different future innovative technologies we imagine that the manufacturing industry will be completely automated, routine medical procedures will be robot-assisted and the world’s most puzzling crimes will be unraveled by robotic-detectives. It’s fair to say that robots have made significant developmental strides since their inception into our society. Although robotic process…

Venus Flytraps Generate Measurable Magnetic Fields
Magnetic fields produced by the venus fly trap have been measured by an interdisciplinary team of scientists. Lily Sharratt-Davidson explores the impact these findings could have on plant diagnostics. The venus flytrap (or Dionaea Muscipula) is a well-recognised carnivorous plant – infamous for its ability to capture small insects inside its cage-like leaves. This unusual…

Should Scotland reintroduce the Eurasian lynx to its highlands?
Samantha Dougary explores whether the Eurasian lynx should be reintroduced back into the Scottish Highlands, to once again be free to roam and thrive in their natural habitat for the first time in 500 years. The Eurasian lynx was once native to Scotland before habitat loss and overhunting drove the species to extinction over 500…
