More than one-third of UK health experts are not aware of Charles Bonnet syndrome — CBS — a condition which can cause vivid, and sometimes frightening, hallucinations.

A poll of 1,100 health experts — including GPs, doctors and optometrists — found 37 per cent were not aware of CBS.

The condition is not caused by mental health problems or dementia. It is purely due to a loss of sight — 60 per cent or more — which reduces or stops the regular messages from the eye to the brain.

Dr. Nadine Lamberski, D.V.M., Dipl. ACZM, Dipl. ECZM (ZHM), is Chief Conservation and Wildlife Health Officer, at the San Diego Zoo Wildlife Alliance (https://sandiegozoowildlifealliance.org/about-us/key-leaders/nadine-lamberski).

Dr. Lamberski leads a unified team of conservation scientists, researchers, wildlife nutritionists, and wildlife veterinarians, cultivating a strategic approach to conservation efforts. She is aligning San Diego Zoo Wildlife Alliance with other global conservation organizations and developing strategies that safeguard biodiversity so all life can thrive.

Novak Djokovic, age 35, sometimes hangs out in a pressurized egg to enrich his blood with oxygen and gives pep talks to glasses of water, hoping to purify them with positive thinking before he drinks them. Tom Brady, 45, evangelizes supposedly age-defying supplements, hydration powders and pliability spheres. LeBron James, 38, is said to spend $1.5 million a year on his body to keep Father Time at bay. While most of their contemporaries have retired, all three of these elite athletes remain marvels of fitness. But in the field of modern health science, they’re amateurs compared to Bryan Johnson.

Middle-aged tech centimillionaire Bryan Johnson and his team of 30 doctors say they have a plan to reboot his body.

For high-cobalt cathodes such as lithium cobalt oxide (LCO) conventional pyrometallurgical (see section ‘Pyrometallurgical recovery’) or hydrometallurgical (see section ‘Hydrometallurgical recovery’) recycling processes can recover around 70% of the cathode value¹¹. However, for other cathode chemistries that are not as cobalt-rich, this figure drops notably¹¹. A 2019 648-lb Nissan Leaf battery, for example, costs US$6,500–8,500 new, but the value of the pure metals in the cathode material is less than US$400 and the cost of the equivalent amount of NMC (an alternative cathode material) is in the region of US$4,000. It is important, therefore, to appreciate that cathode material must be directly recycled (or upcycled) to recover sufficient value. As direct recycling avoids lengthy and expensive purification steps, it could be particularly advantageous for lower-value cathodes such as LiMn₂O₄ and LiFePO₄, where manufacturing of the cathode oxides is the major contributor to cathode costs, embedded energy and carbon dioxide footprint⁹⁵.

Direct recycling also has the advantage that, in principle, all battery components²⁰ can be recovered and re-used after further processing (with the exclusion of separators). Although there is substantial literature regarding the recycling of the cathode component from spent LIBs, research on recycling of the graphitic anode is limited, owing to its lower recovery value. Nevertheless, the successful re-use of mechanically separated graphite anodes from spent batteries has been demonstrated, with similar properties to that of pristine graphite⁹⁶.

Dr Miriam Stoppard writes how the ancient infection leprosy — once such a disfiguring disease that sufferers were exiled — could now help people’s health Leprosy is an ancient infection, common in biblical times, causing such disfiguring disease that sufferers were exiled to isolated colonies miles from anywhere.

A new study has identified a promising drug candidate that can protect neurons from degeneration in mouse models of Parkinson’s disease. The research is published in Science Translational Medicine.

Addressing an unmet need

Parkinson’s disease (PD) is the second most common neurodegenerative disease, and over the last 25 years, the prevalence of PD has doubled, presenting a large health burden across the globe.

The ultraviolet nail polish drying devices used to cure gel manicures may pose more of a public health concern than previously thought. Researchers at the University of California San Diego studied these ultraviolet (UV) light emitting devices, and found that their use leads to cell death and cancer-causing mutations in human cells.

The devices are a common fixture in nail salons, and generally use a particular spectrum of UV light (340-395nm) to cure the chemicals used in gel manicures. While tanning beds use a different spectrum of UV light (280-400nm) that studies have conclusively proven to be carcinogenic, the spectrum used in the nail dryers has not been well studied.

“If you look at the way these devices are presented, they are marketed as safe, with nothing to be concerned about,” said Ludmil Alexandrov, a professor of bioengineering as well as cellular and molecular medicine at UC San Diego, and corresponding author of the study published Jan. 17 in Nature Communications. “But to the best of our knowledge, no one has actually studied these devices and how they affect human cells at the molecular and cellular levels until now.”
