Ransomware Attack on Berlin

• In summer 2023, the ransomware group Rhysida (also linked to Ryuk) breached the network of Berlin's state government.
• The attackers stole 5.8 terabytes of sensitive data, including personnel records, contracts, infrastructure plans, and citizens' data.
• They demanded 30 Bitcoin (around €2 million) as ransom.

How the Breach Happened

• The entry point was a fake CAPTCHA: An employee was tricked into running a terminal command that executed malware.
• The attackers were further helped by plaintext passwords stored in Office documents – a massive security failure.
• Two administration departments were affected: Urban Development and Mobility, Transport, Climate Protection, and Environment.

Berlin's Decision: Refusing to Pay

• Governing Mayor Kai Wegner stated: "Berlin will not be blackmailed."
• The city refused to pay because doing so would not guarantee the deletion of the data and would finance further attacks.
• The deadline passed, and Rhysida published the stolen files in several batches.

Consequences and Impact

• The leak contained highly sensitive information, including salary slips, home addresses, case files, and even vulnerability analyses of the city's water supply.
• Germany's cybersecurity agency BSI warned about phishing emails using real file numbers derived from the leaked data.
• The processing of benefits such as housing subsidies came to a temporary standstill.

Systemic Problems in Germany

• As early as 2019, Berlin's Kammergericht was infected with the Emotet malware – with similarly drastic consequences.
• Berlin's state network is operated separately by different authorities, weakening overall security.
• Germany missed its own deadline to digitalize public services (OZG) by 2022.

Other Examples

• British Library: Rhysida stole 600 GB and published the data after the library refused to pay.
• Ireland: The national health service HSE was hit by Conti; the entire IT network had to be shut down.
• Anhalt-Bitterfeld district: A cyberattack paralyzed local government and triggered the first-ever disaster declaration due to a cyber incident in Germany.

Conclusion

The attack highlights how vulnerable public institutions are when outdated structures meet highly professional extortionists. Refusing to pay was politically understandable but came at a significant cost to those affected. The question remains: Should governments ever pay, or is standing firm the only viable long-term solution?

Introduction

• Dr. Dudley Lamming from the University of Wisconsin-Madison investigates how dietary protein, especially branched-chain amino acids (BCAAs) like isoleucine, leucine, and valine, and mTOR signaling regulate metabolic health and lifespan.
• Protein is essential, but the optimal amount strongly depends on individual activity levels.

Protein Restriction vs. Caloric Restriction

• Research shows that reducing protein intake (e.g., to 7–9 % of calories) in humans leads to weight loss (about 0.68 kg per week), improved blood sugar control, and increased FGF21 – a hormone that boosts metabolism.
• Unlike caloric restriction, protein restriction slightly increases food intake, yet subjects still lose weight.
• Animal studies confirm: Long-term protein restriction extends lifespan and slows frailty in aging.

The Special Role of Isoleucine

• Among the three BCAAs, restricting isoleucine (by about two-thirds) was most effective: It extended median lifespan by 33 % in male mice and by 7 % in females.
• The effect does not appear to be primarily mediated by mTOR inhibition but through other pathways still being explored.
• Valine restriction also extended lifespan by 20 % in males, though it increased mTOR activity in the liver.

Exercise and Protein Needs

• Active individuals benefit from more protein: It supports muscle building and strength gains. In mouse studies, animals on high-protein diets became stronger faster.
• For sedentary individuals, excess protein can have negative metabolic effects: higher risk for diabetes, cardiovascular disease, and obesity.
• Conclusion: Protein is not inherently harmful; its impact depends on whether it is used for muscle maintenance or not.

Older Adults and Sarcopenia

• Older people often have reduced appetite and lower income, which can lead to protein deficiency – this promotes muscle wasting.
• However, too much protein without adequate activity can also be counterproductive.
• Physical exercise (resistance and endurance) is the most important protection against sarcopenia; protein intake should be adjusted to actual needs.

Plant vs. Animal Protein

• Plant-based protein contains slightly fewer BCAAs (about 20 % less) – this may be beneficial for sedentary people.
• Epidemiological studies suggest plant protein is less harmful than red meat, but many other accompanying substances play a role.

Outlook: Personalized Nutrition

• Genetic predisposition influences how strongly one benefits from isoleucine restriction.
• In the future, blood tests could enable individual dietary recommendations („precision nutrition“).

Conclusion

• At least 0.8 g of protein per kg of body weight per day should be achieved (RDA).
• For sedentary people, additional protein supplementation likely yields no benefit and may pose risks.
• Staying active and eating a balanced diet with appropriate protein intake are key to healthy aging.

Short-term situation

• The stock has fallen significantly, and Michael Burry sees a “fat pitch” with potentially 15 % annual returns – that would mean an 8x increase in 15 years.
• He also views it as a rotation candidate: money could flow from the AI boom into value stocks like Zoetis.

Financials

• Revenue is slightly down, but net profit remains profitable, margins and returns are still strong.
• Adjusted EPS: 6; reported: 5.5.
• Cash flow of about $2B per year with a market cap of roughly $42B.
• The P/E ratio of ~12 looks cheap.

Growth & market position

• The animal health market is estimated to grow 10.73% – an oligopoly with three major players.
• 12 new products are in the pipeline; key patents don’t expire until 2030 and 2042.
• Even conservative estimates: 7% market growth + buybacks + dividend yield about 12% annual potential.

Burry's thesis

• Strong focus on share buybacks, partly financed via convertible bonds – management sees the stock as undervalued.
• Uncertainty about US market stabilization (6, 12, or 18 months) scares Wall Street but creates opportunities.
• High return on capital and quality investment – Burry loves such drops in stocks he has watched for years.

Conclusion

• Pharma stocks come with higher volatility – e.g., approval risks or competition – but the risk-reward looks attractive.
• Assessment: rather a buy; placed on the value side of the quadrant model.

Bitcoin Momentum

• Bitcoin has lost momentum, trading below $80k. The market is gripped by uncertainty (midterms, inflation, geopolitical tensions).
• Seasonal effects: Bitcoin typically struggles during midterm years; a recovery is expected from December/January.

Fed Decision

• The Fed held rates hawkishly. A December hike is likely, but may be the last one.
• Ben expects long-term yields to rise before the midterms and fall afterward – similar to 2018.
• Rob notes that a rate hike right before the election would have been politically problematic.

Anthropic IPO

• Anthropic (Claude) filed for IPO. Despite massive losses ($80B), revenue is growing strongly (from $41M to $16B).
• Both guests advise not to buy the IPO immediately; wait for a post-launch correction.
• Capital may be flowing out of crypto into the IPO, contributing to Bitcoin's current weakness.

Midterms & Market Risks

• Polymarket gives a 68% chance that Democrats win the Senate. That would weaken the administration, but historically major legislation passed even under divided government.
• Short-term volatility expected; markets may stabilize afterward.
• Ben predicts a final dip after the midterms before a recovery in early 2027.

Other Risks

• AI Hacks: AI-powered attacks on banks in seven countries – e.g., stolen passwords and cloned voices. €36M was converted to crypto.
• Cryptography Risk: OpenAI's model may have disproven the exponential time hypothesis. If P vs. NP proves equivalent, blockchains could become vulnerable – but no immediate threat.
• Ben shares a probability anecdote (23 people, 50% birthday overlap) to illustrate that probabilities are not certainties.

The Core Insight

• The liking gap: Research from Cornell, Yale, and Harvard shows we underestimate how much others like us.
• The spotlight effect: We think everyone is watching us, but most people are busy with themselves.

Skill 1: PLAY – Stop Self-Monitoring

• P = Projection: Treat the conversation like a movie and get absorbed in the other person.
• L = Liked: Remember the liking gap – the other person likes you more than you think.
• A = Allow: Let yourself be seen. Skip rehearsed scripts and show up authentically.
• Y = Yes: Say yes to your nervousness and reframe it as excitement.

Skill 2: Stones and Seeds – The Art of Questions

• Stones are questions like “What do you do?” that go nowhere.
• Seeds are questions like “Is that what you always wanted to do?” that open up stories.
• Follow-up questions make you more liked (Harvard study) and show that you are truly listening.
• Personal example: The seed “Tell me about your father” would have been invaluable.

Skill 3: Personal, Not Private

• Share personal stories to build connection, but keep private details for close confidants.
• The three rooms model: Porch (small talk), Living room (personal), Bedroom (private).
• Sylvester Stallone shows: worldwide fame does not replace true closeness.

Skill 4: Identify the Conversation’s Purpose

• Three purposes: Solve (offer help), Find out (think out loud), Feel (be heard).
• When criticized, don’t get defensive – look for the underlying concern.
• Talk about observations instead of the person (“You missed the deadline” vs. “You are irresponsible”).
• The most powerful phrase in hard moments: “Can you please help me understand?”

Conclusion

• A single conversation can change your life – and relationships are ultimately one ongoing conversation.

In this Huberman Lab Essentials episode, Andrew Huberman talks with olfactory researcher Dr. Noam Sobel about the fascinating world of smell and how odors unconsciously influence hormones, health, and behavior.

The Anatomy of Smell

• Orthonasal olfaction: Odor molecules travel about 6–7 cm up the nose to the olfactory epithelium.
• There are roughly 7 million receptors of about 350 different types – a significant portion of the human genome is dedicated to this purpose.
• Odorants are converted into neural signals (transduction) and sent via the olfactory nerve to the olfactory bulb.
• In the bulb, all receptors of one type converge onto glomeruli, creating an odor-specific map.
• From the bulb, signals reach the amygdala, hypothalamus, and other brain regions, explaining why smells strongly affect emotions and hormones.

Unconscious Olfactory Behavior

• Humans sniff each other more than they realize. For example, after a handshake, people unconsciously bring their hand to their nose and sniff it – apparently to compare their own scent with that of the other person.
• Click friendships: People who smell similar are more likely to become friends. Using an electronic nose, the formation of friendships could actually be predicted.

Chemosignals and Pheromones

• Fear odor: Humans emit a distinct body odor when afraid, which increases autonomic arousal in others. Fear is contagious – even dogs can smell human fear.
• Hexadecanal: A molecule released in large amounts from baby heads. It reduces aggression in men but increases it in women. Evolutionarily, it protects the offspring: fathers become calmer, mothers more defensive.
• Emotional tears are odorless, yet smelling them lowers testosterone levels by about 14 % in men – a powerful effect that has been independently replicated and also dampens brain activity in regions like the hypothalamus and fusiform gyrus.

The Future: Digitizing Smell

• Dr. Sobel's team developed an algorithm that can predict the perceived similarity of odor mixtures.
• They created olfactory metamers: mixtures with no shared molecules that smell exactly the same – even for Chanel No. 5.
• The foundation for scent transmission over the internet has been established: the first successfully transmitted odor was violet.
• In the long run, digitizing smell could revolutionize medical diagnostics – for instance, with electronic noses in bathrooms detecting diseases by scent.

Bottom line: Smells are far more than just fragrances – they are silent messengers that profoundly shape our social bonds, emotions, and physiological responses.
