Mammalian Tree of Life Redefined: Genomic Time Machine Traces Back 100 Million Years of Evolution

Posted by in categories: biotech/medical, evolution, time travel

The research uses the genomes of 241 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.

Strange but true: the expanding Universe doesn’t conserve energy

Posted by in category: energy

The conservation of energy is one of the most fundamental laws governing our reality. But in the expanding Universe, that’s just not true.

5G Is A Network Security Threat Wake-Up Call For Operators And Regulators

Posted by in categories: cybercrime/malcode, internet

Jan Häglund is the President and CEO of Enea, a specialist in software for telecommunications and cybersecurity.

As mobile networks are increasingly embedded in daily life, they have become a more attractive target for criminals and malicious state actors alike. A new spate of regulations globally suggests a unified response is required.

To consumers, 5G means ultra-fast connectivity and a smoother, better user experience. Few would be aware of how the interconnection and interworking between networks that enables this user experience is itself vulnerable to attack, with more devastating consequences than in the past, as we all increase our reliance on mobile communications.

Technophobia: Causes, Symptoms & Treatment

Posted by in categories: biotech/medical, computing, neuroscience

Technophobia is an extreme fear of technology. People with technophobia may fear the power of artificial intelligence, robots or computers.

Technophobia is more than resistance to learning new technology. Rather, people with the condition may obsess over technology. Or, they may go to great lengths to avoid incorporating technology into their lives.

Technophobia is not a clinical diagnosis in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Still, as technology has expanded rapidly in recent years, some clinicians treat technophobia like a specific phobia. Specific phobias are irrational fears of a particular situation, object, animal or interaction. The fear isn’t in proportion to the actual danger.

How To Use FinOps As A Tool In The Fight Against Rising Cloud Costs

Posted by in categories: economics, security

Scott Sellers is the co-founder and CEO of Azul, with 30 years of experience as an entrepreneur and executive in the technology industry.

For the first time in a decade, controlling cloud costs has surpassed security as the top cloud management challenge facing IT professionals, according to a survey by Flexera. An Andreessen Horowitz study also said that up to $1 trillion in market capitalization is weighed down by overspending in the cloud. Today, challenging economic conditions, rising costs, increasingly stringent performance SLAs and the need for more resources are squeezing organizations that want to remain in the cloud without overspending.

Many organizations still struggle to connect the dots between the value they deliver via the cloud and the costs required to deliver that value. Without a clear understanding of that basic relationship, it is difficult for teams to hold productive conversations about costs. Engineering departments don’t know what to prioritize; cloud architects lack a direction on designing, developing and managing solutions; product managers face difficulties pricing their solutions; and executives wonder where all the money is going.

Chemists are teaching GPT-4 to do chemistry and control lab robots

Posted by in categories: chemistry, robotics/AI

Augmenting the artificial intelligence GPT-4 with extra chemistry knowledge made it much better at planning chemistry experiments, but it refused to make heroin or sarin gas.

New inorganic wide-bandgap perovskite subcells that are both efficient and stable

Posted by in categories: solar power, sustainability

All-perovskite tandem solar cells, stacks of p-n junctions formed from perovskites with different energy bandgaps, have the potential of achieving higher efficiencies than conventional single-junction solar cells. So far, however, most proposed all-perovskite tandem cells have not achieved the desired power conversion efficiencies (PCEs), often due to difficulties associated with creating suitable narrow-and wide-bandgap subcells.

Researchers at Nanjing University and University of Toronto recently developed new inorganic wide-bandgap perovskite subcells that could increase the PCEs and stability of these promising . Their design, introduced in a paper in Nature Energy, involves the insertion of a passivating dipole layer at the interface between organic transport layers and inorganic perovskites within the cells.

“Our research group has been focusing on improving the PCEs of all-perovskite tandem solar cells, which have broken the world record several times and have been included in the ‘solar cell efficiency tables,’” Hairen Tan, one of the researchers who carried out the study, told Tech Xplore.

Scientists Propose Radical New Way to Probe The Interior of The Sun

Posted by in category: biotech/medical

Gravitational wave astronomy is still in its early stages. So far it has focused on the most energetic and distinct sources of gravitational waves, such as the cataclysmic mergers of black holes and neutron stars. But that will change as our gravitational telescopes improve, and it will allow astronomers to explore the Universe in ways previously impossible.

Although gravitational waves have many similarities to light waves, one distinct difference is that most objects are transparent to gravitational waves. Light can be absorbed, scattered, and blocked by matter, but gravitational waves mostly just pass through matter. They can be lensed by the mass of an object, but not fully blocked.

This means that gravitational waves could be used as a tool to peer inside astronomical bodies, similar to the way X-rays or MRIs allow us to see inside a human’s body.
