Marc Andreessen says his A.I. policy conversations in D.C. ‘go very differently’ once China is brought up

Posted by in categories: government, policy, robotics/AI

Marc Andreessen spends a lot of time in Washington, D.C. these days talking to policymakers about artificial intelligence. One thing the Silicon Valley venture capitalist has noticed: When it comes to A.I., he can have two conversations with the “exact same person” that “go very differently” depending on whether China is mentioned.

The first conversation, as he shared on an episode the Joe Rogan Experience released this week, is “generally characterized by the American government very much hating the tech companies right now and wanting to damage them in various ways, and the tech companies wanting to figure out how to fix that.”

Then there’s the second conversation, involving what China plans to do with A.I.

Advances in Traumatic Brain Injury Biomarkers

Posted by in categories: biotech/medical, neuroscience

Traumatic brain injury (TBI) is increasingly a major cause of disability across the globe. The current methods of diagnosis are inadequate at classifying patients and prognosis. TBI is a diagnostic and therapeutic challenge. There is no Food and Drug Administration (FDA)-approved treatment for TBI yet. It took about 16 years of preclinical research to develop accurate and objective diagnostic measures for TBI. Two brain-specific protein biomarkers, namely, ubiquitin C-terminal hydrolase-L1 and glial fibrillary acidic protein, have been extensively characterized. Recently, the two biomarkers were approved by the FDA as the first blood-based biomarker, Brain Trauma Indicator™ (BTI™), via the Breakthrough Devices Program. This scoping review presents (i) TBI diagnosis challenges, (ii) the process behind the FDA approval of biomarkers, and (iii) known unknowns in TBI biomarker biology.

Where does cancer come from?

Posted by in categories: biotech/medical, genetics

We know a lot about cancer, and yet, there is plenty we do not yet know. We do know that some cancers are genetic in nature and a series of changes in key genes can lead to identifiable malignancies down the line. We would certainly want to know what causes cancer in the first place.

Scientists have been trying to replicate the path a cell takes from being normal to becoming pre-cancerous (one of the earliest stages of cancer in which cells become abnormally shaped and sized) for quite some time now. It is a feat that requires human-derived cells to model how cancer comes to be.

Recently, researchers at The Stanford School of Medicine have been able to emulate some of the earliest stages of gastric cancer by starting with gastric organoids (a rudimentary version of the real stomach made from stem-cell-derived gastric cells) that have a single mutation. The study which was published in Nature outlines how the earliest changes in cells could be seen even before the precancerous stage.

Record-Breaking Solar Hydrogen Device: Turning Sunlight Into Clean Energy

Posted by in categories: chemistry, energy

New standard for green hydrogen technology set by Rice U. engineers.

Rice University engineers can turn sunlight into hydrogen with record-breaking efficiency thanks to a device that combines next-generation halide perovskite semiconductors with electrocatalysts in a single, durable, cost-effective and scalable device.

The new technology is a significant step forward for clean energy and could serve as a platform for a wide range of chemical reactions that use solar-harvested electricity to convert feedstocks into fuels.

Bodybuilding supplement helps prevent Alzheimer’s disease

Posted by in categories: biotech/medical, neuroscience

There’s an exciting new development in the field of Alzheimer’s disease research. Surprisingly, it centers around a common bodybuilding supplement known as HMB. The key to preserving memory and staving off this devastating disease may, in fact, reside in the diet of those pumping iron at the gym.

Researchers from RUSH Medical College have recently revealed that the muscle-enhancing supplement known as beta-hydroxy beta-methylbutyrate (HMB) could hold potential in the fight against Alzheimer’s disease.

The supplement, frequently used by bodybuilders to boost muscle growth and enhance performance, might also aid in memory protection, plaque reduction, and slowing the progression of Alzheimer’s disease.

Social genetic effects: Study suggests your romantic partner’s DNA can influence your own health behaviors

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

New research provides evidence that an individual’s health behaviors and outcomes are influenced by the genetic makeup of their romantic partner. The findings, published in Behavior Genetics, indicate that your partner’s genetic tendencies can lead to changes in your own weight, smoking habits, or alcohol consumption over time.

The researchers conducted this study to investigate how a person’s partner can affect their health. They aimed to explore the concept of social genetic effects, which refers to the impact of genetic factors in one person’s environment, such as their partner’s genotype, on their own phenotype (observable characteristics or traits).

“I was mainly interested in exploring the combination of social science and genetics,” explained study author Kasper Otten of Utrecht University. “It is evident that behavior is partly genetically influenced, but much of the social sciences does not deal with this biological fact.

Milk Proteins—Their Biological Activities and Use in Cosmetics and Dermatology

Posted by in categories: biotech/medical, chemistry, food

Milk and colostrum have high biological potential, and due to their natural origin and non-toxicity, they have many uses in cosmetics and dermatology. Research is ongoing on their potential application in other fields of medicine, but there are still few results; most of the published ones are included in this review. These natural products are especially rich in proteins, such as casein, β-lactoglobulin, α-lactalbumin, lactoferrin, immunoglobulins, lactoperoxidase, lysozyme, and growth factors, and possess various antibacterial, antifungal, antiviral, anticancer, antioxidant, immunomodulatory properties, etc. This review describes the physico-chemical properties of milk and colostrum proteins and the natural functions they perform in the body and compares their composition between animal species (cows, goats, and sheep). The milk-and colostrum-based products can be used in dietary supplementation and for performing immunomodulatory functions; they can enhance the effects of certain drugs and can have a lethal effect on pathogenic microorganisms. Milk products are widely used in the treatment of dermatological diseases for promoting the healing of chronic wounds, hastening tissue regeneration, and the treatment of acne vulgaris or plaque psoriasis. They are also increasingly regarded as active ingredients that can improve the condition of the skin by reducing the number of acne lesions and blackheads, regulating sebum secretion, ameliorating inflammatory changes as well as bestowing a range of moisturizing, protective, toning, smoothing, anti-irritation, whitening, soothing, and antiaging effects.

Keywords: milk, colostrum, casein, β-lactoglobulin, α-lactalbumin, lactoferrin, growth factors, skin, regeneration, antimicrobial, cosmetics.

Although milk is known to be used as a raw material in the food industry, it is also widely used in the pharmaceutical and cosmetic industries due to its considerable biological potential. It has also been the subject of detailed analyses and discussions of its individual components and their properties [1, 2].

Metasurface enables strong coupling effects between light and transition metal dichalcogenides

Posted by in categories: energy, nanotechnology

The interaction of light and matter on the nanoscale is a vital aspect of nanophotonics. Resonant nanosystems allow scientists to control and enhance electromagnetic energy at volumes smaller than the wavelength of the incident light. As well as allowing sunlight to be captured much more effectively, they also facilitate improved optical wave-guiding and emissions control. The strong coupling of light with electronic excitation in solid-state materials generates hybridized photonic and electronic states, so-called polaritons, which can exhibit interesting properties such as Bose-Einstein condensation and superfluidity.
