‘The great wealth transfer’ is here: Billionaires set to give trillions to their kids

Posted by in category: business

In recent months, the world’s new billionaires made more of their fortunes from inheritance than from entrepreneurship, according to the UBS Billionaire Ambitions Report.

It marked the first time in the nine-year history of the report that newly minted billionaires accumulated more wealth from inheritance than starting a business.

Fifty-three heirs inherited a total of $150.8 billion in the 12 months ending in April, exceeding the total of $140.7 billion accumulated by 84 new self-made billionaires, according to the Swiss bank’s report. The shift is likely to continue: The report said more than 1,000 billionaires are expected to pass $5.2 trillion to their children over the next 20 or 30 years.

Life on Mercury?


Salt glaciers uncovered on Mercury, the second planet from the sun, could have implications for the habitability of this tiny planet and similar worlds beyond the solar system.

Amazon taps SpaceX’s Falcon 9 rocket to help launch Kuiper satellites

Posted by in categories: business, Elon Musk, internet, satellites

Dec 1 (Reuters) — Amazon (AMZN.O) on Friday said it booked three Falcon 9 launches with Elon Musk’s SpaceX to help deploy the ecommerce giant’s Project Kuiper satellite network, tapping a rival in the satellite internet business for its multi-billion dollar launch campaign.

Amazon aims to build Kuiper as a constellation of 3,236 satellites in low Earth orbit to beam broadband internet globally and compete with SpaceX’s Starlink network, which already has some 5,000 satellites providing nearly global coverage.

Amazon, which vowed in 2019 to invest $10 billion into the project, will put an unspecified number of Kuiper satellites on three Falcon 9 rockets from SpaceX beginning in mid-2025, the company said Friday.

How Epic is using AI to change the way EHRs work

Posted by in categories: biotech/medical, robotics/AI

Sumit Rana, head of research and development, discusses how the EHR giant’s system uses AI to generate progress notes, create draft responses to patient questions and assist with medical coding. And how AI sometimes can be more empathetic than a person.

Spatiotemporal control of RNA metabolism and CRISPR–Cas functions using engineered photoswitchable RNA-binding proteins

Posted by in categories: biotech/medical, engineering

This protocol for the spatiotemporal control of RNA activity uses LicV, a synthetic, photoswitchable RNA-binding protein (RBP) that can bind to a specific RNA sequence in response to blue light irradiation, and provides an efficient and generalizable strategy for engineering photoswitchable RBPs.

Dopamine’s Role in Learning from Rewards and Penalties

Posted by in categories: chemistry, robotics/AI

Summary: Dopamine, a neurotransmitter, plays a vital role in encoding both reward and punishment prediction errors in the human brain.

This study suggests that dopamine is essential for learning from both positive and negative experiences, enabling the brain to adapt behavior based on outcomes. Using electrochemical techniques and machine learning, scientists measured dopamine levels in real-time during a computer game involving rewards and penalties.

The findings shed light on the intricate role of dopamine in human behavior and could have implications for understanding psychiatric and neurological disorders.

Shedding light on the synthesis of sugars before the origin of life

Posted by in category: chemistry

Pentoses are essential carbohydrates in the metabolism of modern lifeforms, but their availability during early Earth is unclear since these molecules are unstable.

A new study, published in the journal JACS Au and led by the Earth-Life Science Institute (ELSI) at Tokyo Institute of Technology, Japan, reveals a chemical pathway compatible with early Earth conditions and by which C6 aldonates could have acted as a source of pentoses without the need for enzymes. Their findings provide clues about primitive biochemistry and bring us closer to understanding the Origins of Life.

The emergence of life on Earth from simple chemicals is one of the most exciting yet challenging topics in biochemistry and perhaps all of science. Modern lifeforms can transform nutrients into all sorts of compounds through complex chemical networks; what’s more, they can catalyze very specific transformations using enzymes, achieving a very fine control over what molecules are produced.

Diamond-stretching technique makes qubits more stable and controllable

Posted by in categories: cybercrime/malcode, energy, quantum physics

Researchers are claiming a breakthrough in quantum communications, thanks to a new diamond-stretching technique they say greatly increases the temperatures at which qubits remain entangled, while also making them microwave-controllable.

Quantum networking is an emerging field that uses weird quantum phenomena to send and receive information. These networks will be impossible to hack, and will use quantum entanglement to cover large distances, creating pairs of qubits which mirror each other’s quantum state without any physical connection.

Diamond-based qubits are capable of maintaining their state of entanglement for a decent length of time – but only provided they’re kept incredibly cold – just a hair above absolute zero. That limits their usefulness, because it’d mean you’d need a giant, energy-intensive cooling apparatus at every node of your quantum network.

UK Biobank Releases Whole Genome Data from Half a Million People

Posted by in categories: biotech/medical, genetics, health

After five years, more than 350,000 hours of genome sequencing, and over £200 million of investment, UK Biobank is releasing the world’s largest-by-far single set of human sequencing data—completing the most ambitious project of its kind ever undertaken. The new data, whole genome sequences of its half a million participants, will certainly drive the discovery of new diagnostics, treatments, and cures. Uniquely, the data are available to approved researchers worldwide, via a protected database containing only de-identified data.

This advance lies not only in the abundance of genomic data, but its use in combination with the existing data UK Biobank has collected over the past 15 years on lifestyle, whole body imaging scans, health information, and proteins found in the blood. The Pharma Proteomics Project was published last month in Nature, in the paper, “Plasma proteomic associations with genetics and health in the UK Biobank.

Looking forward, these data could be used to further advance efforts such as more targeted drug discovery and development, discovering thousands of disease-causing noncoding genetic variants, accelerating precision medicine, and understanding the biological underpinnings of disease.
