Nutritional Modulation of Polycystic Ovary Syndrome (PCOS): A Metabolic and Hormonal Perspective A representation of the symptomatic exhibition Credits: Dr. Manisha Jain Abstract Polycystic Ovary Syndrome (PCOS) is a complex endocrine–metabolic disorder characterized by hormonal imbalance, insulin resistance, and chronic low-grade inflammation. Emerging evidence highlights nutrition as a primary, non-pharmacological intervention capable of restoring metabolic homeostasis. This blog presents a structured, scientific overview of how dietary composition influences PCOS pathophysiology, emphasizing glycemic control, macronutrient optimization, anti-inflammatory strategies, and sustainable lifestyle integration. 1. Understanding PCOS as a Metabolic-Endocrine Disorder 1.1 Definition and Prevalence PCOS affects women of reproductive age and manifests through: Oligo- or anovulation Hyperandrogenism Polycystic ovarian morphology Beyond reproductive...

Insomnia Keeps Brain in Daytime Mode

Why Your Brain Won't Switch Off at Night: The Insomnia Clock Glitch Revealed Tired of a racing mind stealing your sleep? A groundbreaking University of South Australia study uncovers why chronic insomnia keeps your brain locked in high-alert "daytime mode" deep into the night—it's not just stress, it's a circadian rhythm breakdown.​ Insomnia traps the brain in daytime mode—alert, restless, and unable to power down—turning night into an extension of wakefulness rather than a gateway to recovery. Photo by Megan te Boekhorst on Unsplash The Lab Discovery That Changes Everything In a 24-hour "constant routine" experiment, 16 insomniacs and 16 good sleepers stayed awake in dim-lit bedrest, logging thoughts hourly on tone, quality, and control. Healthy brains peaked in afternoon problem-solving, then plunged to nighttime disengagement. Insomniacs? Peaks delayed by 6.5 hours, with blunted drops—staying goal-directed and emotionally engaged when they should pow...

How to write a blog

What do you really need to write a blog? Once you start, you don't stop, you improve day by day Credits: Fresh Science Trends Acclimatization Phase: First things first; what really is a blog?  A blog is a regularly updated online publication—either a single web page or a full website—where one or more authors share content such as articles, news, opinions, tutorials, or personal stories, usually arranged with the newest posts first and often allowing reader comments or interaction. The term comes from “weblog,” originally meaning a personal or topical log on the web, and today covers everything from casual diaries and niche hobby sites to professional news outlets and business content hubs. Choose which blogsite you will choose to make your blog.  For an easier blogging approach, start with simple, hosted platforms that handle all the tech for you: WordPress.com and Blogger are beginner‑friendly, free (with upgrades), and good for article‑style blogs.​ Medium and Substack le...

Tricking the brain to make exercise feel easier

Hack Your Brain to Make Workouts Feel Effortless: The Tendon Vibration Trick Dread the burn of a jog or bike ride? New research shows you can "trick" your brain into perceiving exercise as easier—pushing harder without feeling it. Breath, balance, and sunrise light: where strength feels soft and movement turns into quiet meditation Photo by kike vega on Unsplash The Simple Experiment Université de Montréal's Prof. Benjamin Pageaux strapped vibrating devices to volunteers' Achilles and knee tendons for 10 minutes before a 3-minute cycling test. Result? Same perceived effort, but higher power output and heart rates—muscles worked harder while brains registered "moderate." ​ How Vibration Rewires Effort Vibration tweaks spinal neurons and neuromuscular spindles, scrambling signals to the brain about movement strain. "It alters perception, making tough feel tolerable," Pageaux explains. Published in  Journal of Sport and Health Science , this boosts m...

Warmth and Hugging Strengthen the Feeling of Being You

-
Image
Warm hugs do more than feel nice—they quietly tune the nervous system, deepen body awareness, and strengthen the sense of “this is me.” When a warm hug melts the world away and, for a moment, you remember exactly who you are and who you belong to. Photo by  Anastasia Vityukova  on  Unsplash Why warmth changes how you feel about yourself A new review from Queen Mary University of London and the University of Pavia highlights “thermoception,” the brain’s reading of skin temperature, as a direct skin‑to‑brain channel for shaping bodily self‑awareness. When the skin feels warmth—from a hug, a blanket, or a heated room—the brain updates its internal map of the body, reinforcing the feeling that the body belongs to us and grounding our sense of self. These temperature signals don’t just keep us alive and comfortable; they influence emotion, identity, and how present we feel in our own skin. When temperature signals go wrong The authors show that disturbed thermal perception oft...

IUDs: Methods of Birth Control

-
Image
Intrauterine devices ( IUDs ) are small T-shaped devices inserted into the uterus to prevent pregnancy , working primarily by creating a hostile environment for sperm and eggs. They come in two main types: copper IUDs , which release copper ions to immobilize sperm , and hormonal IUDs , which release progestin to thicken cervical mucus . Progesterone vs Progestin Progesterone is a natural hormone released from the corpus luteum after ovulation. It dominates the luteal phase, converts the endometrium into the secretory phase, supports implantation, and maintains pregnancy. It's fall causes menstruation. Progestins are synthetic forms used in contraceptive s. They act by negative feedback on the hypothalamus and pituitary, suppressing LH and FSH, thus preventing ovulation. They also thicken cervical mucus, blocking sperm entry, and thin the endometrium, making implantation unlikely. Hence progestins mimic progesterone but are used to prevent pregnancy .      Copper IUD Mec...

Surgical Methods of Contraception

-
Image
Surgical methods of contraception offer a permanent , highly effective way to prevent pregnancy for individuals or couples who are sure their families are complete. The two key procedures are vasectomy for males and tubal ligation (tubectomy) for females , each working by safely blocking the path of sperm or egg so fertilization cannot occur while leaving sexual function and hormones largely unaffected. The videos below provide a simple visual walk‑through of how these procedures are done, what happens inside the reproductive tract, and why they are considered more than 99% effective as long‑term birth control options .

How the Brain Edits Your Past: The Science of Storing and Reshaping Personal Memories

-
Image
Your memories aren't dusty old files—they're living stories your brain rewrites every time you revisit them. Episodic memory retrieval involves the reactivation of the cognitive and neural processes which were active when the event was initially experienced. Credit: Neuroscience & Biobehavioral Reviews (2025). DOI: 10.1016/j.neubiorev.2025.106417 Why Memories Shift A groundbreaking University of East Anglia study uncovers how episodic memories, like that unforgettable birthday bash or family vacation, aren't static snapshots. Instead, they're dynamic networks of active details (easy to recall) and hidden traces that spring alive with the right trigger. Lead researcher Prof. Louis Renoult reveals these memories must trace back to real past events, but recall blends in imagination, general knowledge, or your current mood, making each version slightly different. The Brain's Rewriting Magic Deep in the hippocampus, memories form as dormant traces waiting for cues—li...

The Silent Struggle of Long COVID's Smell Loss

-
Image
Author: Anneswa Das Olfactory dysfunction (OD) means reduced or decreased smell sensation. Also it is most recognized symptoms of COVID‐19. There's a term called "long COVID". In May 2020, Dr. Elisa Perego used the term "#LongCovid" on twitter to describe the symptoms that stayed with her even after she recovered from the main COVID-19 infection. Many other people who felt the same way started using the term too. It became common in online support groups before doctors and researchers began using it in medical studies. So in a simple way, Long COVID refers to a range of symptoms that continue for weeks, months, or even years after the initial COVID-19 infection has resolved. Recovery isn’t always recovery. Long COVID can steal the sense of smell, turning flowers into silence Photo by Alexander Grey on Unsplash Losing the sense of smell or taste has become one of the symptoms people most commonly associated with COVID-19. In the early days of the pandemic, nea...
