International researchers studying the yellow crazy ant, or Anoplolepis gracilipes, found that male ants of this species are chimeras, containing two genomes from different parent cells within their bodies. This unique reproductive process, originating from a single fertilized egg that undergoes separate maternal and paternal nuclear division, is unprecedented and challenges the fundamental biological inheritance law stating that all cells of an individual should contain the same genome.

The yellow crazy ant, known scientifically as Anoplolepis gracilipes, is notorious for being one of the most devastating invasive species.

A species is a group of living organisms that share a set of common characteristics and are able to breed and produce fertile offspring. The concept of a species is important in biology as it is used to classify and organize the diversity of life. There are different ways to define a species, but the most widely accepted one is the biological species concept, which defines a species as a group of organisms that can interbreed and produce viable offspring in nature. This definition is widely used in evolutionary biology and ecology to identify and classify living organisms.

Anosognosia is a condition in which a patient is unaware of their neurological deficit or psychiatric condition. Visual anosognosia, also called Anton syndrome, is associated with complete cortical blindness and unawareness of vision loss.

Researchers from Brigham and Women’s Hospital, a founding member of the Mass General Brigham healthcare system, sought to identify brain network connections associated with anosognosia. The investigators analyzed the connectivity patterns of 267 lesion locations associated with either vision loss (with and without awareness) or weakness (with and without awareness).

Henry Molaison, known for years as “H.M.,” was famously unable to form new memories. If someone he had met left the room only to return several minutes later, he would greet that person again as if for the first time. Because of surgery to treat intractable epilepsy, H M. lacked a sea-horse-shaped brain structure called the hippocampus and had amnesia. His case helped establish the hippocampus as an engine of memory.

In recent years scientists have discovered another essential deficit that burdens people with hippocampal amnesia: they can’t envision the range of possibilities that must be considered to make future plans. When researchers asked a group of people with hippocampal damage to… More.

The ability to conjure up possible futures or alternative realities is the flip side of memory. Both faculties cohabit in the brain region called the hippocampus.

From gene expression to protein design, large language models are creating a suite of powerful genomic tools for DNA analysis.

Billionaire investor Li Ka-Shing is funding a new technology that can potentially rival artificial intelligence (AI) by using brain cells blended with computers in a technology it calls DishBrain.

Peter Thiel, Mark Cuban and Warren Buffet funded early-stage startups and made millions. You don’t need to be a well-connected billionaire to do the same. Click here to invest in promising startups today.

This science fiction-sounding tech comes from Australian biotech firm Cortical Labs. The company recently raised $10 million in a round led by Horizons Ventures, the investment vehicle of the 94-year-old Ka-Shing, the richest person in Hong Kong. Additional investors included Blackbird Ventures, an Australian venture capital (VC) fund; In-Q-Tel, the investment arm of the Central Intelligence Agency; U.S. firm LifeX Ventures; and others.

Today Loremasters we explore some of hyper technology of the Necrons – the World Engine, Celestial Orrery & the Dolmen Gates.

Masters of Material Technology

The Necrons are the masters of Material technology, and their technological feats may seem magical to lesser races. Their technological masters, Crypteks, can manipulate matter at a fundamental level and wield such arcane concepts as phase-gates, subatomic infusion, and temporal looping. Several Necron super-weapons such as the World Engine and Celestial Orrery have galaxy-devastating capabilities. However it is Living Metal, or Necrodermis, which equips nearly all Necron technology. These billion-strong swarns of nano–Scarabs crawl under the skin of Necrons at a cellular level, allowing for self-repair and regeneration. Also, on particularly rare occasions, a super heavy Necron device called a Necron Pylon is seen. It is feared for its extreme power and ability to appear anywhere on the battlefield.

Stem cell differentiation paths found to permit U-turns, provided mitochondrial signaling loop is engaged.

For the first time, researchers from Tel Aviv University have developed a genome-scale technology that makes it possible to reveal the role of genes and traits in plants previously hidden by functional redundancy.

The researchers point out that since the agricultural revolution, man has improved plant varieties for agricultural purposes by creating genetic diversity. But until this recent development, it was only possible to examine the functions of single genes, which make up only 20% of the genome. For the remaining 80% of the genome, made up of genes grouped in families, there was no effective way, on the large scale of the whole genome, to determine their role in the plant.

As a result of this unique development, the team of researchers managed to isolate and identify dozens of new features that had been overlooked until now. The development is expected to revolutionize the way agricultural crops are improved as it can be applied to most crops and agricultural traits, such as increased yield and resistance to drought or pests.
