Year Ender 2023: List of Discoveries in 2023

The end of one year and the start of the next always seem to bring about a period of reflection. The passage of time symbolized by the changing year is a revered and honored life milestone. How did this year vary from the previous one? Did you meet any of the goals you set for yourself at the start of the year? Regardless of the year-or a catastrophic global pandemic-the pace of innovation in science never slows. Even in archeology, we discover something new every year. Let's take a look at some of the professional successes of scientists and archeologists this year as we reflect on our own personal milestones in the coming month. This is not an exhaustive list, but rather a compilation of advancements:

Scientific Discoveries in 2023

AI jumps leaps and bounds

ChatGPT and other AI platforms launched to instant and widespread global interest. Artificial intelligence systems quickly invaded virtually every field, including science. Throughout the year, headlines focused on what ChatGPT and other AI were achieving in research experiments.

First wiring map of insect brain

In March, researchers at the University of Cambridge created the first map of every neuron and how they are linked together in the brain of a fruit fly larva. The map of 3,016 neurons and 548,000 synapses is the most comprehensive brain connectome ever created. It represents a significant advancement over past efforts to image relatively simple brain structures such as the roundworm.

Synthetic human embryos created from stem cells

Scientists at the University of Cambridge and the California Institute of Technology used stem cells to generate synthetic human embryos, a ground-breaking breakthrough that eliminates the need for eggs or sperm. The model embryos, which are similar to those in the early stages of human development, could provide an important window into the impact of genetic abnormalities and the biochemical causes of recurrent miscarriage. However, the work poses severe ethical and legal concerns because the lab-grown entities are not covered by present legislation in most nations.

First successful transplant of functional cryopreserved rat kidney

Researchers at the University of Minnesota demonstrated for the first time that rat kidneys can be cryogenically stored for up to 100 days, successfully rewarmed using a novel approach, cleared of cryoprotective fluids and nanoparticles, and successfully transplanted into rats to restore full kidney function. The unique nano warming technique rapidly and uniformly warms the organ from within rather than merely at its surface.

First vaccine for pregnant individuals to prevent RSV in infants

The FDA approved the first vaccination for use in pregnant women to prevent RSV in infants from birth to 6 months of age in August. Abrysvo is licensed for usage between 32 and 36 weeks of pregnancy. It is given as a single injection into the muscle. Abrysvo lowered the risk of severe lower respiratory tract disease (LRTD) by 81.8% within 90 days of birth and 69.4% within 180 days of birth in clinical trials. When compared to placebo, Abrysvo lowered the incidence of lower respiratory tract disease by 57.3% within 180 days of birth and by 76.5% for severe LRTD.

Earth has enough raw materials to switch to renewable energy

A team of scientists published a new analysis in January that found the globe has enough rare earth minerals and other important raw materials to transition from fossil fuels to renewable energy and minimize global warming. A group of scientists examined the materials, many of which had not previously been significantly mined, as well as 20 different power sources.

Archeological Discoveries in 2023

This year saw a number of significant discoveries in the field of archaeology. Let us have a look.

57,000-Year-Old Neanderthal Markings Found in a Sealed French Cave

Scientists examined hundreds of wavy lines, spots, and subtle striations left on the longest and most even wall of an ancient cave in La Roche-Cotard, France's Loire Valley. Neanderthals sweeping and pressing their fingertips across a thin brown film on the limestone walls appear to have left the traces. However, it is unclear what they mean. These are the oldest known Neanderthal markings, dating back more than 57,000 years.

4,500-Year-Old Lost Ancient Palace Unearthed in Iraq

A lost palace from the ancient Sumerian city of Girsu was discovered in southern Iraq using drone photography. Archaeologists discovered the subterranean ruins of a previously unknown huge complex at the Tablet Hill site near Tello. The team discovered the Eninnu temple, the principal sanctuary of the Sumerian god Ningirsu, the ancient city's namesake. Prior to this discovery, the temple was only known from inscriptions discovered at the site 140 years ago.

Prison Bakery Found at Pompeii

Archaeologists discovered the remnants of a prison bakery where enslaved individuals were locked up with donkeys and forced to crush grain for baking bread. Only little windows are protected with iron bars at the top of the wall in the compact chamber. The creatures that would have walked together, blinded, for hours in synchronized work have left indentations on the floor. These discoveries give new light on the ancient world's enslavement. It is "a space in which we have to imagine the presence of people of servile status," said Pompeii director Gabriel Zuchtriegel in a statement.

The Oldest Pearl-Fishing City Discovered in the Arabian Gulf

Archaeologists discovered the world's oldest-known pearl-fishing settlement on the island of Al-Siniyah off the coast of Umm Al Quwain in the United Arab Emirates. The 12-acre fishing city, located about 30 miles northeast of Dubai, most likely had thousands of residents and was active year-round between the late sixth century and the middle of the eighth century, prior to the entrance of Islam in the area. This is the first time archeological evidence has proven their existence, which had previously only been documented in ancient books.

1,800-Year-Old Roman City Unearthed in Luxor, Egypt

Egyptian researchers discovered a whole residential Roman city dating from the second and third centuries CE in Luxor. According to Egypt's Supreme Council of Antiquities, this latest site is the "oldest and most important city found on the eastern bank of Luxor." There, the crew discovered a number of residential buildings, two pigeon towers for carrier birds, and metal workshops, as well as a treasure of pots, tools, and bronze and copper Roman coins inside the workshops.

An Ancient Housing Complex was Uncovered at Chichen Itza in Mexico

The first known dwellings within Chichen Itza's city limits are a set of constructions thought to be part of an elite housing complex. An entry arch, the House of the Snails, the House of the Moon, and the Palace of the Phalluses are all part of the complex. Chichen Itza is a Maya ruin complex in Mexico's Yucatán peninsula that dates back to the 5th century CE. The city, which was administered by the Maya elite and functioned as a pilgrimage site for the ancient Maya, especially during times of drought, is a UNESCO World Heritage Site and one of the world's seven wonders.
