There might be room for everyone, or not. At first glance, the connections between the world’s growing population and climate change seem obvious. The more people we have on this planet, the larger their collective impact on the climate.

The global population is projected to reach 8 billion on 15 November 2022, and India is projected to surpass China as the world’s most populous country in 2023, according to World Population Prospects 2022, released today on World Population Day.

“This year’s World Population Day falls during a milestone year, when we anticipate the birth of the Earth’s eight billionth inhabitant. This is an occasion to celebrate our diversity, recognize our common humanity, and marvel at advancements in health that have extended lifespans and dramatically reduced maternal and child mortality rates,” said UN Secretary-General António Guterres. “At the same time, it is a reminder of our shared responsibility to care for our planet and a moment to reflect on where we still fall short of our commitments to one another,” he added.

The global population is growing at its slowest rate since 1950, having fallen under 1 per cent in 2020. The latest projections by the United Nations suggest that the world’s population could grow to around 8.5 billion in 2030 and 9.7 billion in 2050. It is projected to reach a peak of around 10.4 billion people during the 2080s and to remain at that level until 2100.

Glaucoma impacts tens of millions of people globally, and is the second leading cause of blindness, after cataracts. Now, Purdue University researchers have developed smart contact lenses that may help save people’s sight.

Glaucoma is a multifactorial optic degenerative neuropathy characterized by the loss of retinal ganglion cells. It is a combination of vascular, genetic, anatomical, and immune factors. Glaucoma poses a significant public health concern as it is the second leading cause of blindness after cataracts, and this blindness is usually irreversible. It is estimated that 57.5 million people worldwide are affected by primary open-angle glaucoma (POAG). People over 60 years of age, family members of those already diagnosed with glaucoma, steroid users, diabetics, as well as those with high myopia, hypertension, central cornea thickness of.

As LHC Run 3 gets into its stride and the first results at a new energy frontier roll in (p5), all eyes are on what’s next: the High-Luminosity LHC (HL-LHC), scheduled to start operations in 2029. Civil engineering for the major upgrade is complete (p7) and new crystal collimators for HL-LHC operations are to be put to the test during the current run (p35). Looking beyond the LHC, how best to deal with the millions of cubic metres of excavation materials from a future circular collider? (p9), and a new project to explore the use of high-temperature superconductors for FCC-ee (p8). The HL-LHC and proposed future colliders also feature large in the recent US Snowmass community planning exercise (p23).

Beer is one of the oldest and most popular beverages in the world, with some people loving and others hating the distinct, bitter taste of the hops used to flavor its many varieties. But an especially “hoppy” brew might have unique health benefits. Recent research published in ACS Chemical Neuroscience reports that chemicals extracted from hop flowers can, in lab dishes, inhibit the clumping of amyloid beta proteins, which is associated with Alzheimer’s disease (AD).

AD is a debilitating neurodegenerative disease, often marked by memory loss and personality changes in older adults. Part of the difficulty in treating the disease is the time lag between the start of underlying biochemical processes and the onset of symptoms, with several years separating them. This means that irreversible damage to the nervous system occurs before one even realizes they may have the disease. Accordingly, preventative strategies and therapeutics that can intervene before symptoms appear are of increasing interest.

One of these strategies involves “nutraceuticals,” or foods that have some type of medicinal or nutritional function. The hop flowers used to flavor beers have been explored as one of these potential nutraceuticals, with previous studies suggesting that the plant could interfere with the accumulation of amyloid beta proteins associated with AD. So, Cristina Airoldi, Alessandro Palmioli and colleagues wanted to investigate which chemical compounds in hops had this effect.

Recently, two patients in the United Kingdom received two small doses of lab-grown blood samples as part of the RESTORE trial.

About the RESTORE trial

The RESTORE trial is a single-center, randomized, controlled, phase I cross-over trial that is a joint effort between the National Health Service (NHS) Blood and Transplant (NHSBT) and the University of Bristol. The aim of this trial is to determine whether blood cells manufactured from donor stem cells perform better than red blood cells (RBCs) obtained from the same donor in recipients.

Wearable technology is capable of tracking various measures of human health and is getting better all the time. New research shows how this could come to mean real-time feedback on posture and body mechanics. A research team at Cornell University has demonstrated this functionality in a novel camera system for the wrist, which it hopes to work into smartwatches of the future.

The system is dubbed BodyTrak and comes from the same lab behind a face-tracking wearable we looked at earlier in the year that is able to recreate facial expressions on a digital avatar through sonar. This time around, the group made use of a tiny dime-sized RGB camera and a customized AI to construct models of the entire body.

The camera is worn on the wrist and relays basic images of body parts in motion to a deep neural network, which had been trained to turn these snippets into virtual recreations of the body. This works in real time and fills in the blanks left by the camera’s images to construct 3D models of the body in 14 different poses.

Americans endlessly chatter about what to eat. Low fat, high protein, vegan, ketogenic — but what about electronic? Since the turn of the 21st century, a dedicated group of scientists, engineers, and technologists has been trying to create edible electronics, not necessarily for human nutrition, but rather for medical purposes.

Electronic devices composed of digestible materials that gradually break down in the body over a matter of days could precisely deliver medication inside the body and measure drug uptake. They could monitor symptoms of gastrointestinal disorders and the gut microbiome. They could allow doctors to remotely observe patients’ internal health without a visit to the hospital, further enhancing the telehealth revolution and allowing more people access to healthcare.

Several proteins have been identified in hosts that interact with Ebola virus and primarily function to inhibit the production of viral genetic material in cells and prevent Ebola virus infection, according to a study led by the Institute for Biomedical Sciences at Georgia State University.

Zaire ebolavirus or Ebola virus, an RNA virus pathogen that belongs to the filovirus family, causes outbreaks of severe disease in humans. This public health threat has produced outbreaks where reported case fatality rates ranged up to 90 percent.

The West Africa Ebola virus epidemic from 2013–2016 resulted in more than 28,000 infections and more than 11,000 deaths. Four outbreaks occurred in the Democratic Republic of Congo from 2017–2021 and Ebola virus reemerged in Guinea in 2021.

On 30 January 2020 COVID-19 was declared a Public Health Emergency of International Concern (PHEIC) with an official death toll of 171. By 31 December 2020, this figure stood at 1 813 188. Yet preliminary estimates suggest the total number of global deaths attributable to the COVID-19 pandemic in 2020 is at least 3 million, representing 1.2 million more deaths than officially reported.

With the latest COVID-19 deaths reported to WHO now exceeding 3.3 million, based on the excess mortality estimates produced for 2020, we are likely facing a significant undercount of total deaths directly and indirectly attributed to COVID-19.

COVID-19 deaths are a key indicator to track the evolution of the pandemic. However, many countries still lack functioning civil registration and vital statistics systems with the capacity to provide accurate, complete and timely data on births, deaths and causes of death. A recent assessment of health information systems capacity in 133 countries found that the percentage of registered deaths ranged from 98% in the European region to only 10% in the African region.
