The AI Revolution In Healthcare: How Data Science Is Transforming Drug Discovery And Medical Diagnosis

Going forward, AI has the potential to help balance needs across regions, ensuring care delivery doesn’t compromise chronic or long-term care in the face of emergencies.

Ethical Considerations And Systemic Impact

While AI holds significant promise in healthcare, its implementation must be approached thoughtfully. Challenges such as bias in training data, lack of interoperability and concerns around patient consent and data privacy (particularly under HIPAA) need to be proactively addressed. Effective deployment of AI requires close collaboration between policymakers, clinicians and technologists to establish standards that ensure equitable and inclusive outcomes.

Cosmic sculptor: Astronomers spot young planet shaping spiral arms in dusty stellar disk

Astronomers may have caught a still-forming planet in action, carving out an intricate pattern in the gas and dust that surrounds its young host star. Using ESO’s Very Large Telescope (VLT), they observed a planetary disk with prominent spiral arms, finding clear signs of a planet nestled in its inner regions. This is the first time astronomers have detected a planet candidate embedded inside a disk spiral.

“We will never witness the formation of Earth, but here, around a young star 440 light-years away, we may be watching a planet come into existence in real time,” says Francesco Maio, a doctoral researcher at the University of Florence, Italy, and lead author of this study, published in Astronomy & Astrophysics.

The potential planet-in-the-making was detected around the star HD 135344B, within a disk of gas and dust around it called a . The budding planet is estimated to be twice the size of Jupiter and as far from its host star as Neptune is from the sun. It has been observed shaping its surroundings within the protoplanetary disk as it grows into a fully formed planet.

Genetic test predicts obesity in childhood

What if we could prevent people from developing obesity? The World Obesity Federation expects more than half the global population to develop overweight or obesity by 2035. However, treatment strategies such as lifestyle change, surgery and medications are not universally available or effective.

By drawing on genetic data from over five million people, an international team of researchers has created a genetic test called a (PGS) that predicts adulthood obesity already in early childhood. This finding could help to identify children and adolescents at higher genetic risk of developing obesity, who could benefit from targeted preventative strategies, such as lifestyle interventions, at a younger age.

“What makes the score so powerful is its ability to predict, before the age of five, whether a child is likely to develop obesity in adulthood, well before other risk factors start to shape their weight later in childhood. Intervening at this point can have a huge impact,” says Assistant Professor Roelof Smit from the NNF Center for Basic Metabolic Research (CBMR) at the University of Copenhagen and lead author of the research published in Nature Medicine.

Genetically modified gut bacteria show promise for combating kidney stones in clinical trial

The human gut microbiome has been shown to impact health in a myriad of ways. The type and abundance of different bacteria can impact everything from the immune system to the nervous system. Now, researchers at Stanford University are taking advantage of the microbiome’s potential for fighting disease by genetically modifying certain bacteria to reduce a substance that causes kidney stones. If scientists are successful at modifying gut bacteria, this can lead to therapeutic treatments for a wide range of diseases.

However, the study, published in Science, shows that this is not a simple task. The researchers used the bacterium Phocaeicola vulgatus, which is already found in the microbiome of humans, and modified it to break down and also to consume porphyran, a nutrient derived from seaweed. The porphyran was used as a way to control the population of Phocaeicola vulgatus by either adding more porphyran or reducing the amount, which should kill off the bacteria due to a lack of food.

The study was made up of three parts: one testing the modified bacteria on rats, one trial with healthy humans and one trial on people with enteric hyperoxaluria (EH). EH is a condition in which the body absorbs too much oxalate from food, leading to and other kidney issues, if not treated.

Scientists twist DNA into self-building nanostructures that could transform technology

Scientists have used DNA's self-assembling properties to engineer intricate moiré superlattices at the nanometer scale—structures that twist and layer like never before. With clever molecular “blueprints,” they’ve created customizable lattices featuring patterns such as honeycombs and squares, all with remarkable precision. These new architectures are more than just scientific art—they open doors to revolutionizing how we control light, sound, electrons, and even spin in next-gen materials.

Rapidus Prototypes 2-nm Transistors for 2027 Ramp

Last month, Japanese startup foundry Rapidus began prototyping 2-nanometer gate-all-around (GAA) transistors at its new facility, a key step toward ramping up its first production in 2027.

The foundry, which aims to compete with TSMC and Samsung in leading-edge chips for AI, said in a press statement that in about three years, it has reached target milestones, including the fab groundbreaking in September 2023, clean room completion in 2024, and, in June this year, the installation of production equipment.

Rapidus and TSMC are two chipmakers that the Japanese government is relying on to revive the nation’s declining semiconductor industry. Rapidus, if successful, will make leading-edge 2-nm chips for companies like IBM. TSMC is producing 12-to 28-nanometer chips for image sensors and automotive applications at its base in Kumamoto, Japan.

Life on Venus? Probe mission could search Venus clouds for unexplained hydrogen-rich gases

The answer to whether tiny bacterial life-forms really do exist in the clouds of Venus could be revealed once and for all by a UK-backed mission.

Over the past five years, researchers have detected the presence of two potential biomarkers—the gases phosphine and ammonia—which on Earth can only be produced by biological activity and industrial processes.

Their existence in the Venusian clouds cannot easily be explained by known atmospheric or geological phenomena, so Cardiff University’s Professor Jane Greaves and her team are plotting a way to get to the bottom of it.

Wellesley team’s new research on anesthesia unlocks important clues about the nature of consciousness

For decades, one of the most fundamental and vexing questions in neuroscience has been: what is the physical basis of consciousness in the brain? Most researchers favor classical models, based on classical physics, while a minority have argued that consciousness must be quantum in nature, and that its brain basis is a collective quantum vibration of “microtubule” proteins inside neurons.

New research by Wellesley College professor Mike Wiest and a group of Wellesley College undergraduate students has yielded important experimental results relevant to this debate, by examining how anesthesia affects the brain. Wiest and his research team found that when they gave rats a drug that binds to microtubules, it took the rats significantly longer to fall unconscious under an anesthetic gas. The research team’s microtubule-binding drug interfered with the anesthetic action, thus supporting the idea that the anesthetic acts on microtubules to cause unconsciousness.

“Since we don’t know of another (i.e,. classical) way that anesthetic binding to microtubules would generally reduce brain activity and cause unconsciousness,” Wiest says, “this finding supports the quantum model of consciousness.”
