In this case, filaments radiate away from a “zombie star” the explosion created. Then, in 2023, astronomers spied weird filaments glowing with light from sulfur within the nebula. Scientists know the supernova created the filaments, but it’s unclear how or when the structures formed. The robust data that the instrument captured allowed the team to measure the motions of each filament and create a 3D map. The Keck Cosmic Web Imager enabled measurements of the velocity of any material within the nebula that emits light.

Not having — or losing — your sense of smell may be linked to changes in breathing that could lead to depression, social isolation or other mental and physical health problems, a new study suggests. About 72% of those completely regained their sense of smell, while about a quarter partially got their sense of smell back. Previous research has linked anosmia to a wide variety of negative outcomes, ranging from dulled emotions and depression to a shortened lifespan, the authors noted. It was a game changer.”Currently, health care providers often don’t ask about or test for anosmia, Parma said. “And when there is a pleasant smell, the brain tells the nose to increase the amount of air inhaled.

On Thursday, Seed Health launched CODA, a computational biology platform funded by its consumer business profitability. Seed Health has been in the business of microbiome scientific breakthroughs since its founding in 2015, but its biggest success to-date may have been becoming profitable as a bioscience startup. Katz's co-founder and co-CEO at Seed Health, Raja Dhir, said CODA and the accompanying data set will help to standardize microbiome science methods, which has long been an issue in the field. CODA's first applications are in metabolic health, brain health, longevity, and menopause, research areas chosen because they have already been identified as areas of human health where early CODA data displayed the strongest evidence. Seed Health has been working on several efforts around pioneering microbiome science for human and planetary health, and many in the field believe the approach is destined to have wider applications.

CNN —Researchers in India have for the first time documented how Asian elephants bury dead calves. While African elephants are known to bury dead calves, this is the first time that the behavior has been documented in Asian elephants, study author Akashdeep Roy, a researcher at the Indian Institute of Science Education and Research (IISER), told CNN on Wednesday. A dead calf being dragged by an adult. This is the first time that calf burials by Asian elephants have been documented. Roy contests this theory, explaining that contusions on the backs of the dead calves show that they were dragged to their resting place by other members of the herd.

CNN —Scientists based in China have created a monkey chimera with two sets of DNA, experimental work they say could ultimately benefit medical research and the conservation of endangered species. It’s the world’s first live birth of a primate chimera created with stem cells, the researchers said. Scientists have created mouse embryos that are part human, and in 2021, scientists reported that they had grown human-monkey chimeric embryos. In September, researchers reported that they had grown kidneys containing mostly human cells inside pig embryos. Then they selected a subset of cells to inject into genetically distinct 4- to 5-day-old embryos from the same monkey species.

Lab models of human embryos raise hopes and concerns
  + stars: | 2023-10-26 | by ( Katie Hunt | ) edition.cnn.com   time to read: +14 min
From the moment sperm fuses with an egg, human embryo development involves a string of complex and little understood processes. What happens during human embryo development, particularly in the crucial first month, remains largely unknown. However, 14 days is an important milestone because it is when permitted lab research on cultured human embryos routinely ends. He said, in the future, it might be possible to go as far as 40 days with human embryo models. Some in the field envision a “tipping point” wherein human embryo models might be afforded some protection like those surrounding human embryos, as scientific advances diminish the differences between the embryo models and their real-life counterparts.

Demonstrators hold placards next to a banner as they attend a protest against the sharing of Cauvery river water with neighbouring Tamil Nadu state, in Bengaluru, India, September 26, 2023. Schools and colleges were shut in the capital of the southern state of Karnataka, home to more than 3,500 tech companies. "I can shed my blood but I don't want to give water to Tamil Nadu," said one protester, Ravi Mallikarjuna. The delay provoked small demonstrations near a railway station in Tamil Nadu. The Cauvery river originates in the Karnataka region of Talakaveri, flowing through Tamil Nadu into the Bay of Bengal.

CNN —Hundreds of millions of years ago, jawless fishes swam Earth’s seas, their brains protected on the outside by armored skin, and on the inside by plates made of cartilage. Scientists are still piecing together how modern vertebrates’ skulls evolved from these ancient fish ancestors, which were the first animals with backbones. The specimen — an articulated cranium that’s 455 million years old — belongs to the jawless fish Eriptychius americanus. Modern vertebrate descendants of jawless fishes make up two groups: vertebrates with jaws, and jawless hagfish and lampreys. “So it’s quite exciting.”Extracting the detailsThe fossilized head cartilage was excavated in 1949 and described in 1967 by the late paleontologist Robert Denison, a curator of fossil fishes at Chicago’s Field Museum of Natural History.

REHOVOT, Israel (Reuters) - Scientists in Israel have created a model of a human embryo from stem cells in the laboratory, without using sperm, eggs or a womb, offering a unique glimpse into the early stages of embryonic development. "The question is, when does an embryo model become considered an embryo? At the moment we are really, really far off from that point," said team leader Jacob Hanna. "None of these models fully recapitulate natural human development but each adds to ways in which many aspects of human development can now be studied experimentally," she said. The study raises some ethical questions over the possibility of potential future manipulation in human embryo development, Hanna and others noted.

CNN —There is a “gravity hole” in the Indian Ocean — a spot where Earth’s gravitational pull is weaker, its mass is lower than normal, and the sea level dips by over 328 feet (100 meters). The “gravity hole” in the Indian Ocean — officially called the Indian Ocean geoid low — is the lowest point in that geoid and its biggest gravitational anomaly, forming a circular depression that starts just off India’s southern tip and covers about 1.2 million square miles (3 million square kilometers). In six of the scenarios, a geoid low similar to the one in the Indian Ocean formed. The future of the geoid lowThe geoid low formed around 20 million years ago, according to the team’s calculation. Past research only simulated the descent of cold material across the mantle, rather than including hot rising mantle plumes as well.

There's a gravity hole in the Indian Ocean, where ocean levels are about 300 feet lower than surrounding areas. The gravity hole may have been caused by an ancient ocean bed that sank millions of years ago. But a new study suggests researchers should have been looking around, not under, the gravity hole to solve the mystery of how it formed. The blue dot over the Indian Ocean is a gravity 'hole' that has scientists baffled. But scientists have struggled to explain the gravity hole in the Indian Ocean, known as the Indian Ocean geoid low.

Scientists Debut Lab Models of Human Embryos
  + stars: | 2023-06-24 | by ( Carl Zimmer | ) www.nytimes.com   time to read: +1 min
In its first week, a fertilized human egg develops into a hollow ball of 200 cells and then implants itself on the wall of the uterus. Over the next three weeks, it divides into the distinct tissues of a human body. And those crucial few weeks remain, for the most part, a black box. Dr. Hanna and a number of other biologists are trying to uncover those details by creating models of human embryos in the lab. They are coaxing stem cells to organize themselves into clumps that take on some of the crucial hallmarks of real embryos.

A rare pod of orcas washed up dead on a beach in Chile late last year, according to LiveScience. It was only the second time in recorded history the Type D orcas had been found stranded. It's the first mass stranding of these killer whales in 67 years and only the second event of its kind in recorded history, according to LiveScience. Type D orcas have one of the highest levels of inbreeding of any mammalLittle is known about Type D orcas, since they tend to live in especially turbulent and rough seas in the Southern Pacific where few boats venture. The researchers found an almost identical genetic code between Type D orcas in Chile and the skeleton of a Type D that was beached in New Zealand.

However, Russia's invasion of Ukraine, which has dented economies around the world, is contributing to growth slowing down in Indonesia. The food sector has been strongly affected by the war in Ukraine, which has disrupted wheat and fertilizer imports into Indonesia. After recording economic growth of 5.3% in 2022, the strongest for almost a decade, Indonesia is now braced for growth to slow down intensified by Russia's invasion of Ukraine. With weakening commodity and energy prices denting export earnings, Indonesia is contending with economic headwinds as fears of a global recession mount. Indonesia, one of Asia's success stories of recent years, has been less hard-hit than many emerging economies by the war in Ukraine.

The war in Ukraine has lent new urgency to Taiwan military's efforts to bolster defence including a push to develop drones. NCSIST head Art Chang said the war in Ukraine had focused attention on drones, and his institution had teamed up with Taiwan companies to build a "national team" to develop military drones. President Tsai Ing-wen has championed the idea of "asymmetric warfare" to make Taiwan's forces more mobile and harder to attack. China has sent its drones to areas close to Taiwan to test its responses, the island's defence ministry has said.
TAIPEI, Feb 7 (Reuters) - Taiwan will speed up development of drones for military use taking into account the lessons of the war in Ukraine and the threat posed by China, the island's defence ministry said on Tuesday. Unmanned aircraft have played a crucial role on both sides since Russia launched a full-scale invasion of Ukraine in February last year. Taiwan Defence Ministry spokesperson Sun Li-fang told reporters that the island is speeding up the development and production of drones. Chi Li-ping, director of the institute's Aeronautical Systems Research Division, detailed drones in development for the military, including for reconnaissance purposes. Taiwan has also had to deal with Chinese drones which have buzzed Taiwan-controlled islands off the Chinese coast.
