Long-term, low-dose THC can improve cognitive decline in mice

Long-term, low-dose THC can improve cognitive decline in mice

HealthPharmacy

By Rosa García-Verdugo

One of the hallmarks of aging is cognitive decline. New research in mice shows that long-term administration with tetrahydrocannabinol (THC), the primary psicoactive component of marihuana, at low doses can have antiaging-effects, particularly on cognitive decline. The endocannabinoid system (ECS) regulates various bodily and brain functions, including sleep, memory and learning, the immune system and […]

Author: Rachel Gordon, Massachusetts Institute of Technology In 1994, Florida jewelry designer Diana Duyser discovered what she believed to be the Virgin Mary’s image in a grilled cheese sandwich, which she preserved and later auctioned for $28,000. But how much do we really understand about pareidolia, the phenomenon of seeing faces and patterns in objects […]

Iberian lynx’s potential secret weapon against extinction

BiologyGenetics

By Invited Researcher

Many large mammals have lost genetic diversity, often thanks to the actions of people shrinking their populations. The implications can be severe because without genetic diversity, a population does not have a “genetic database” to fall back on to adapt to environmental change. The Iberian lynx (Lynx pardinus) is no stranger to this reduction in […]

One-electron carbon bond observed for first time Chemists have observed for the first time covalent bonds between two carbon atoms with only one electron, a bonding behavior that deepens the understanding of chemical bonds. “We aim to clarify what a covalent bond is — specifically, at what point does a bond qualify as covalent, and […]

Catalysis in industry is often driven by empirical investigations and, eventually, by unexpected discoveries. Frequently, the scientific understanding of the process takes much longer to develop. Ideally, it would be preferable to reverse this timeline, where scientific insights precede application. Nonetheless, even when the scientific explanation takes more time, a deep understanding of the underlying […]

Author: Ramón Muñoz-Chápuli has been Professor of Animal Biology in the University of Málaga until his retirement. He has investigated for forty years in the fields of developmental biology and animal evolution. Lungfish (Dipnoi) are fascinating animals. Despite having gills, they can breathe atmospheric air thanks to a pair of lungs. Their geographic distribution aligns […]

Liquid crystals are all around us, from cell phone screens and video game consoles to car dashboards and medical devices. Run an electric current through liquid crystal displays (LCDs) and they generate colours, thanks to the unique properties of these fluids: rearrange their shape, and they reflect different wavelengths of light. As the lab of […]
