Climate change and habitat loss are poised to drive over 500 bird species to extinction within the next century, according to a study conducted by researchers at the University of Reading.Published in Nature Ecology & Evolution, the study points to the severity of the threat, revealing that this number is three times greater than all recorded bird extinctions since 1500 CE.advertisementNotable species such as the bare-necked umbrellabird and the helmeted hornbill are among those at risk, with their loss expected to significantly impact ecosystems reliant on these birds for essential functions.

The study found that even eliminating human-induced threats like habitat destruction, hunting, and climate change would not fully prevent bird extinctions."Many birds are already so threatened that reducing human impacts alone won't save them. These species need special recovery programmes, like breeding projects and habitat restoration, to survive," said Kerry Stewart, the study's lead author.The research, which examined nearly 10,000 bird species using IUCN Red List data, identified that larger birds are particularly vulnerable to hunting and climate change, while those with wider wings are more affected by habitat loss.advertisementKerry Stewart further elaborated on the urgency of the situation, stating, "We face a bird extinction crisis unprecedented in modern times.

She added that prioritising conservation for the most unusual birds could preserve a significant diversity of bird shapes and sizes, which is crucial for maintaining ecosystem health. The findings indicate that stopping habitat destruction would save the greatest number of birds overall.

Can zapping your brain with electricity improve math skills? Yes

Are you also afraid of algebra, trigonometry and geometry? Well, scientiests have found a new way to enhance math skills - zapping your brain with electricity.A recent study published in PLOS Biology reveals that a painless, non-invasive brain stimulation method can significantly enhance math learning in young adults, especially those who struggle due to how their brain regions is a critical skill for many careers in science, technology, engineering, and finance. Yet, a 2016 OECD report found that nearly a quarter to a third of adults in developed countries have math skills comparable to a seven-year-old. This lack of numeracy is linked to lower income, poorer health, reduced political engagement, and diminished social Educational gaps often widen over time — a phenomenon called the Matthew effect — where students who start ahead continue to outperform their peers. While socioeconomic factors and motivation play roles, biological factors such as genetics, brain connectivity, and chemical signalling have been shown to strongly influence learning outcomes, including in investigate this, researchers recruited 72 young adults aged 18 to 30 and taught them new math calculation techniques over five days. Some participants received a placebo, while others underwent transcranial random noise stimulation (tRNS), a gentle electrical current applied non-invasively to the brain. Believe it or not, the fear of math is real- and it's got a name: math anxiety. (Photo: Getty) advertisementThe stimulation was targeted to either the dorsolateral prefrontal cortex (involved in memory and attention during learning) or the posterior parietal cortex (important for processing math after learning).Brain scans and neurochemical measurements, including levels of gamma-aminobutyric acid (GABA), were taken before and after training. Participants with weaker natural connectivity between the prefrontal and parietal regions — typically linked to poorer learning — showed significant improvement when tRNS was applied over the prefrontal cortex, effectively helping them catch up with peers who had stronger brain mechanism behind this improvement may be 'stochastic resonance,' where adding a small amount of random noise helps weak neural signals become clearer, boosting underperforming neurons closer to their activation tRNS does not enhance already strong learners but helps level the playing field, offering a promising tool to reduce educational inequalities rooted in brain the study focused on healthy university students, similar benefits have been observed in children with math learning disabilities and breakthrough suggests a future where personalised, brain-based interventions complement traditional education, helping learners overcome biological barriers while continuing to address social and systemic challenges.- EndsMust Watch

Why hundreds of birds may go extinct in the next coming years

Birds enrich our world with their vibrant colors, and movements, playing crucial roles in pollination, pest control, and seed dispersal. However, a recent study warns that climate change and habitat destruction are putting global bird diversity at risk. The potential loss of unique species like the bare-necked umbrellabird and helmeted hornbill could severely impact ecosystems. Projections suggest that up to 250 bird species may disappear, even with conservation efforts, with some being too vulnerable to survive without direct intervention. How climate and hunting threaten global bird diversity According to a recent study published in the journal Nature Ecology & Evolution analysing nearly 10,000 bird species found that birds are particularly vulnerable due to hunting pressure and climate stress. Birds with broad wings, often found in forests, are especially threatened by habitat destruction. The expected loss of these species could lead to a 3.2% decline in global bird functional diversity over the next century, which may seem small but would have significant ecosystem impacts. Large, unique birds often play irreplaceable roles, and their disappearance would leave gaps that other birds cannot fill, ultimately damaging the ecosystem balance. Why do hundreds of birds need more than just a safer habitat Researchers found that even in the best-case scenario, where all human threats are eliminated, around 250 species would still face extinction. This accounts for nearly half of the projected losses, highlighting that some species are too vulnerable to survive without targeted conservation efforts. Birds like the Cebu flowerpecker, with fewer than 70 individuals remaining, may require specific interventions like habitat restoration or captive breeding to prevent their disappearance. The study emphasizes that reducing threats alone is insufficient, as past damage and small, isolated populations continue to pose significant risks. Addressing specific threats to the unique birds Habitat loss affects over 1,600 bird species, but other threats like hunting and accidental deaths have a greater impact on preserving unique bird traits. Reducing these specific threats can be more effective in conserving rare bird features, even if it doesn't save as many species overall. Certain birds, such as those with long tails and short beaks, are more vulnerable to hunting, and those with broad wings are more affected by habitat destruction. This insight can inform targeted conservation efforts. Protecting birds that shape our ecosystem With 100 functionally unique species protected, over two-thirds of the global functional diversity of birds could be protected. These species, like nectar-feeders or seed dispersers, serve vital ecological roles with unique characteristics. Certainly, by saving around 37 of those, we could achieve this - since 1993, 21-32 have already been protected. This might be successful with a few years of dedicated conservation.
