In the remote forests of South Dakota, a state-of-the-art laboratory is where scientists are examining one of the deepest puzzles of physics: the reason behind the existence of the universe. Along with them, a rival team in Japan which is currently years ahead is also pursuing the same question, setting the stage for a global scientific race.
The prevailing models of the Universe's origin are trying to examine why matter, from galaxies to planets, exists in such abundance. To explore this mystery , both teams are constructing sophisticated detectors designed to study
neutrinos
that are elusive subatomic particles that may hold critical clues.

To reach the heart of their experiment, scientists will descend 1,500 meters beneath the Earth's surface into three enormous underground chambers. The scale of the excavation is so immense that construction crews and their machinery appear dwarfed, like miniature models in a vast diorama.
Now, the facility is entering a critical phase as the Deep Underground Neutrino Experiment (DUNE) is ready to begin building its detectors which is an international collaboration involving over 1,400 scientists from 35 countries, united by one goal that is to understand the reason behind the existence of universe in its current form.
According to prevailing theories, the birth of the Universe produced equal quantities of matter and antimatter which are mirror versions of each other. In theory, these should have destroyed one another, leaving behind nothing but pure energy. And yet, matter remains—forming the stars, planets, and life itself. The mystery of that imbalance is what Deep Underground Neutrino Experiment aims to resolve.
To uncover why matter succeeded over antimatter and why we exist at all, scientists are turning their focus to one of the Universe's most elusive particles: the neutrino, and its antimatter counterpart, the antineutrino.
The experiment involves firing high-energy beams of these particles from a site in Illinois, sending them on an 800-mile journey underground to sophisticated detectors in South Dakota. As they travel, neutrinos and antineutrinos subtly shift their identities in a process known as oscillation.
Researchers aim to determine whether the behavior of neutrinos differs from that of antineutrinos. If such a difference exists, it may offer the long-sought explanation for why the early Universe didn't self-eradicate in a burst of energy and why matter and ultimately life survived.
The Deep Underground Neutrino Experiment (DUNE) brings together a global team of over 1,400 scientists from 30 nations. Among them is Dr. Kate Shaw of the University of Sussex describes the project's potential as "transformative" for both physics and our broader understanding of humanity's place in the cosmos.
Japan launches Hyper-Kamiokande
On the other side of the globe, a team of Japanese scientists is also on the hunt for answers to one of physics' deepest mysteries. Inside a vast facility enhanced with glowing golden spheres, they are constructing
Hyper-Kamiokande
- a next generation neutrino detector set to surpass its predecessor named Super-Kamiokande in both scale and sensitivity.
The vast chamber, with its reflective surfaces and golden glow, resembles a shrine to scientific discovery mirroring the grandeur of the underground halls at the Deep Underground Neutrino Experiment in South Dakota which is located at some 6,000 miles away.
Hyper-K is part of a major international collaboration, and its neutrino beam is expected to go online in under three years and well ahead of the U.S.-based project.
Although experts have different views on it as some think that having both experiments operational will ultimately benefit the scientific community providing complementary data and stronger results. While the race is underway, the first results from both experiments won't be available for several years. For now, the question of what triggered the beginning of time and ultimately led to our existence is what makes people curious to know about the facts behind this mystery.

Vitamin D supplements and their link with ageing: 5 unbelievable facts
Vitamin D, crucial for bone health and immunity, may also combat aging. A study revealed that vitamin D supplements help maintain telomere length, potentially delaying biological aging by nearly three years. Furthermore, it supports cardiovascular health, improves mood, and aids in weight management, highlighting its multifaceted benefits for overall well-being. Soak in the sunshine every morning. That daily dose of vitamin D can do wonders for your health. Vitamin D, also known as the 'sunshine vitamin', plays a critical role in bone health, immune function, and overall well-being. Recent research also suggests that it may help reverse age! A recent study led by researchers at Mass General Brigham and the Medical College of Georgia found that vitamin D supplements show signs of protection against biological aging. The findings are published in The American Journal of Clinical Nutrition . What is vitamin D Vitamin D is a fat-soluble nutrient essential for maintaining healthy bones, supporting immune function, and promoting overall well-being. It is produced by the skin when exposed to sunlight and can also be consumed from animal-based foods such as salmon, cod, and egg yolks. Vitamin D and ageing The recent controlled trial revealed that vitamin D supplementation helps to maintain telomeres, the protective caps found at the ends of chromosomes that shorten during aging and are linked to the development of certain diseases. 'VITAL is the first large-scale and long-term randomized trial to show that vitamin D supplements protect telomeres and preserve telomere length. This is of particular interest because VITAL had also shown benefits of vitamin D in reducing inflammation and lowering risks of selected chronic diseases of aging, such as advanced cancer and autoimmune disease,' co-author JoAnn Manson, MD, principal investigator and chief of the Division of Preventive Medicine at Brigham and Women's Hospital, said in a release. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Giao dịch CFD với công nghệ và tốc độ tốt hơn IC Markets Đăng ký Undo Easy ways to increase your Vitamin D intake The study followed over 1,000 participants for four years and found that those who took vitamin D3 supplementation daily had slowed the process of telomere shortening. This means it delayed biological aging by nearly three years. The shortening of the telomeres is also linked to increased risk of many age-related diseases. 'Targeted vitamin D supplementation may be a promising strategy to counter a biological aging process, although further research is warranted,' the researchers noted. Vitamin D and immunity Studies have also found that a low level of vitamin D increased the risk of infections and autoimmune diseases, such as rheumatoid arthritis, type 1 diabetes, and inflammatory bowel disease. A 2020 study found that vitamin D can improve immune health and decrease the susceptibility to autoimmune diseases. Vitamin D and cardiovascular health Vitamin D plays a crucial role in fighting disease. Low levels of vitamin D are linked to increased risk of cardiovascular diseases, including hypertension, coronary artery disease, ischemic heart disease, heart failure, stroke, and type 2 diabetes. A systemic analysis and meta-analysis conducted by scientists from institutions across China and the United States in 2024 found that targeted vitamin D supplementation can improve cardiometabolic health. The analysis found that vitamin D supplementation was associated with favorable effects on various cardiometabolic risk factors, including reductions in systolic and diastolic blood pressure, total cholesterol, fasting blood glucose, hemoglobin A1C, and fasting blood insulin. Vitamin D and mood Studies have shown that vitamin D plays a key role in decreasing the risk of depression and also regulating mood. A 2020 systematic review and meta-analysis of 7,534 people found that vitamin D supplementation can reduce negative emotions. Researchers noted that patients with major depressive disorder and individuals with vitamin D deficiency are most likely to benefit from supplementation. Vitamin D and weight loss Vitamin D has also shown promise in weight management. A 2018 study looked at the effects of vitamin D supplementation on weight Loss, glycemic indices, and lipid profile in obese and overweight Women. After 6 weeks of supplementation in obese and overweight women aged 20–40 years, the researchers found a reduction in the mean of BMI, weight, and waist circumference.

Explainer: What is agro-terrorism and fusarium graminearum threat fueling the US-China tensions?
The recent arrest of a Chinese researcher and charges against another for smuggling a dangerous crop-killing fungus into the United States have brought renewed attention to the threat of agro-terrorism. At the heart of the case is Fusarium graminearum, a potent plant pathogen capable of devastating cereal crops and disrupting national food supplies. US officials allege the two researchers, one of whom worked at a University of Michigan lab, intended to conduct unauthorized research on the fungus—raising fears of deliberate attempts to compromise American agriculture. The incident, unfolding amid heightened US-China tensions and trade disputes, highlights how scientific collaboration can be exploited to target a country's most vulnerable infrastructure: its food system. What is agro-terrorism? Agro-terrorism is the intentional use of biological agents—such as plant pathogens, pests, or contaminants—to attack a country's agricultural infrastructure. It targets food production systems with the aim of causing economic devastation, food insecurity, and public panic. Agro-terrorism is attractive to hostile actors because it is low-cost, difficult to detect, and capable of triggering far-reaching economic and social damage. Why agriculture is a soft target Agriculture-based sectors are especially vulnerable. Unlike military or financial systems, farms, food processing plants, and supply chains are less protected and widely dispersed. Biological attacks on crops or livestock can go undetected for weeks and are difficult to trace back to the perpetrators. This makes agro-terrorism a potent weapon for countries or groups seeking to destabilize a rival nation. Fusarium graminearum: A potent agro-terrorism threat At the center of the current controversy is Fusarium graminearum, a fungus that causes Fusarium head blight—a disease that ravages cereal crops such as wheat, barley, maize, and rice. The fungus not only decimates yields but also produces a toxin called vomitoxin (deoxynivalenol), making the grain unsafe for human and animal consumption. According to the US Department of Agriculture, this disease causes over $1 billion in crop losses annually in the United States alone. Vomitoxin can cause vomiting, diarrhea, abdominal pain, and fever in livestock and people, further amplifying its public health impact. The case: Chinese researchers charged Two Chinese nationals, Yunqing Jian (33) and Zunyong Liu (34), have been charged by US federal prosecutors with smuggling Fusarium graminearum into the United States—without proper permits and under false pretenses. Jian, who works at the University of Michigan, is currently in US custody. Liu, her boyfriend and a researcher in China, is believed to be in China and remains at large. According to the FBI, Liu carried baggies of the fungus into the US via the Detroit airport and initially lied about them. He later admitted he intended to use them for research in a Michigan lab. Jian allegedly received Chinese government funding for similar research and has expressed loyalty to the Chinese Communist Party (CCP). US Attorney Jerome Gorgon Jr. described the smuggling as a 'national security' concern, emphasizing the CCP ties and the threat to America's food supply. Why this matters Although Fusarium graminearum already exists in the US, the unauthorised import of foreign strains is dangerous. Variants may be more virulent, pesticide-resistant, or adapted to new climates—making them harder to contain. Bringing them in without the proper biosecurity controls risks new outbreaks or genetic mutations that existing defenses can't manage. FBI Director Kash Patel warned that this could have "grave consequences... putting American lives and our economy at serious risk." He emphasised that this case illustrates how state-backed actors may attempt to infiltrate US institutions and compromise critical sectors like food security. Wider context: US-China tensions This incident comes amid deteriorating relations between Washington and Beijing. US-China trade talks stall after Geneva tariff truce Trade negotiations between the United States and China have stalled, just weeks after both sides agreed in Geneva to a 90-day cooling-off period by reducing tariffs. The agreement had seen China cut tariffs on American goods from 125% to 10%, while the U.S. proposed lowering its tariffs on Chinese imports from 145% to 30%. However, progress has faltered amid renewed tensions. U.S. President Donald Trump reignited the dispute on May 30, accusing China of 'totally violating' the Geneva deal, though he did not provide specifics. 'So much for being Mr. NICE GUY!' he wrote on social media. In response, China's Commerce Ministry denied any violations and accused Washington of making 'bogus charges' and taking 'unreasonable' actions, including export controls on AI chips and revoking Chinese student visas. The Trump administration has also recently announced a crackdown on Chinese student visas, citing national security threats. US Secretary of State Marco Rubio pledged to 'aggressively revoke' visas for Chinese students in sensitive research fields—moves Beijing has denounced as 'discriminatory.'

Harvard Professor beats inbox lag, Allahabad Professor still in ‘seen' limbo": Delhi boy's post goes viral
Writing a research paper is a mammoth task in itself, and the task is made more tedious when we await the replies from experts or professors. The late replies can be explained due to the tight schedule, too many emails, or simple disinterest. But a recent X post from a student has brought to light something deeper: the realization that hierarchy and accessibility don't always go hand in hand. The X post, which has gone viral on X, reads as follows: 'A professor from Harvard University with 500–600 cited papers replied within one hour of me sending my email, and a professor from Allahabad University with 4 cited papers can't see my mail sent a month ago.' — twinkythough (@twinkythough) The post has sparked conversation in the comment section of the post, with some narrating their own similar incidents. One user said, 'Same. I recently sent a connection to a person in LinkedIn. He has over 30 yrs experience and an impeccable track record and currently works for a government in Middle East region. He responded to me in few mins and gave me 5-6 contacts. Meanwhile, my past colleagues need me to remind them every week about the same thing. ' Another user pointed out, 'Not to dispute the evident problems in Indian academia but it's entirely possible that the Prof in India is way more overburdened with admin and teaching duties than his counterpart in Harvard. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Giao dịch CFD với công nghệ và tốc độ tốt hơn IC Markets Tìm hiểu thêm Undo Not to mention the probable difference in number of students hired.' It's true that there's a stark difference in the professor-to-student ratio between institutions like Harvard and most Indian universities. While Harvard boasts a ratio of 1:7, ensuring more individual attention and manageable workloads, Indian universities typically operate with a ratio closer to 1:26—making it significantly harder for professors to engage with every student who reaches out. A third user remarked that this lack of empathy and consideration in Indian academicians risese from the fact that most of them dont like their job. They wrote, 'I''ve always talked about this. Here majority of the teachers and professors are not in love with their profession and just doing it as a job . They lack enthusiasm and grit which is the cornerstone of teaching. Again I'm talking about the majority.' However, some pointed out that the user's experience could be a one-off case of good luck. They shared that they, too, had reached out to people in high positions, but rarely received a response. Whatever the odds, the incident has highlighted a troubling divide—students today are more connected than ever, yet still struggle to access meaningful academic support. When emails go unanswered and curiosity meets silence, it sends a quiet message: that reaching out doesn't always mean being heard.
