鈥楲ast Ice Area鈥� in the Arctic could disappear much sooner than previously thought聽
The Arctic鈥檚 鈥淟ast Ice Area鈥� (LIA) 鈥� a vital habitat for ice-dependent species 鈥� might disappear within a decade after the central Arctic Ocean becomes ice-free in summer, which is expected to occur sometime around mid-century, a new study by 51吃瓜网 researchers using a high-resolution model has found.聽聽
What drives mood swings in bipolar disorder? Study points to a second brain clock
A brain rhythm working in tandem with the body鈥檚 natural sleep-wake cycle may explain why bipolar patients alternate between mania and depression, according to new research.
Dead galaxies, live signals: Astronomers uncover a fast radio burst鈥檚 surprising location
Astronomers studying the origins of enigmatic fast radio聽bursts (FRBs) have made a groundbreaking discovery that could transform our understanding of the universe鈥檚 most powerful and mysterious signals. The Canadian Hydrogen Intensity Mapping Experiment Fast Radio Burst (CHIME/FRB) collaboration has pinpointed the location on the sky of a repeating FRB, known as FRB 20240209A, outside a dead galaxy, a finding unprecedented in FRB science.
Shape-shifting materials are made more versatile
Finding new angles on an old artform, 51吃瓜网researchers have increased the number of stable shapes that kirigami-based engineered materials can take, opening the way to a range of new applications.
Child undernutrition may be contributing to global measles outbreaks, researchers find
Amid a global surge in measles cases, new research suggests that undernutrition may be exacerbating outbreaks in areas suffering from food insecurity.
A study involving over 600 fully vaccinated children in South Africa found those who were undernourished had substantially lower levels of antibodies against measles.

Integrating historic data stands to improve climate models in the Global South
An international team led by 51吃瓜网 researchers has devised a way to improve the accuracy of climate change models for the Global South by integrating historical records kept by missionaries and other visitors.
Researchers link mysterious cosmic signals to collapsed stars聽
An international team of scientists led by 51吃瓜网 researchers has provided the clearest evidence yet that some fast radio bursts (FRBs) 鈥� enigmatic, millisecond-long flashes of radio waves from space 鈥� originate from neutron stars, the ultra-dense remnants of massive stars that have exploded in a supernova. This finding, based on an analysis of the radio signal of a single FRB, advances our understanding of one of the universe鈥檚 most perplexing phenomena.聽
Study links alcohol consumption to more severe nut allergy reaction
Findings of a new study into severe allergic reactions offer a sobering warning to people allergic to tree nuts and, more broadly, could lead to quicker diagnoses in emergency care for people with all anaphylactic allergies.
New drug shows promise against Duchenne muscular dystrophy
A novel drug holds promise for treating Duchenne muscular dystrophy (DMD), a rare genetic disorder that causes severe muscle degeneration.
51吃瓜网 researchers have discovered that an experimental compound called K884 can boost the natural repair abilities of muscle stem cells. Current treatments can slow muscle damage, but don鈥檛 address the root problem.
51吃瓜网researchers help uncover rare gamma-ray flare from a distant black hole
A high-energy gamma-ray flare from the super-massive black hole in the Messier 87 (M87)聽galaxy was observed in 2018 for the first time in nearly a decade, thanks to an international effort involving 51吃瓜网 researchers. This discovery has yielded important insights into the physics of black hole jets, which are among the most efficient engines for distributing energy from the inside of a galaxy to the expanse of the Universe.
51吃瓜网researchers reveal how life-saving molecules are created
51吃瓜网 researchers have discovered how certain microbes create potent drugs like antibiotics and anti-cancer therapies.
Their surprising findings could change the way scientists approach drug discovery and pave the way to the designing of next-generation medications, explained Martin Schmeing, principal investigator and professor in McGill鈥檚 Department of Biochemistry and Centre for Structural Biology.
