Large-scale ocean circulation is a key regulator in the redistribution of oceanic energy. Under the background of global warming, how the ocean circulation will change is an essential question, the answer of which relies on observations. A recent paper published by Science China Earth Sciences presented significant trends in the tropical Pacific western boundary currents, through analyzing six-decade historical hydrological observations.

The new study, published in Physical Review Letters, simulated 25,000 scenarios of black holes and neutron stars colliding, aiming to see how many would likely be detected by instruments on Earth in the mid- to late-2020s. The researchers found that, by 2030, instruments on Earth could sense ripples in space-time caused by up to 3,000 such collisions, and that for around 100 of these events, telescopes would also see accompanying explosions of light.

An automated system that uses artificial intelligence (AI) is effective at detecting a common type of wrist fracture on X-rays, according to a new study. Researchers said the AI-derived algorithm could help speed diagnosis and allow earlier treatment.

Patients with advanced colorectal cancer may be spared from a toxic side effect caused by a type of targeted therapy used to treat the cancer with the help of another drug normally used to treat melanoma.

Scientists led by Dr Jason Heaney from Baylor College of Medicine in Texas, USA, have found that a failure in the development of sperm cells can lead to the formation of testicular tumours in mice. These findings, published in the journal Development, provide new clues for understanding how testicular cancer arises in mammals.

Bone collagen of fish shows individual history of migration and eating habits throughout life history

Researchers at the University of California, Riverside, have used a nanoscale synthetic antiferromagnet to control the interaction between magnons -- research that could lead to faster and more energy-efficient computers.

More sleep could offset children's excess indulgence over the school holidays as new research from the University of South Australia shows that the same decline in body mass index may be achieved by either extra sleep or extra exercise.

Exercising enough can prevent weight gain. Researchers have found a simple measurement method that helps to maintain or reduce weight- and it's free.

New Curtin research has found urgent action is needed to ensure man-made underwater noise in Australian waters does not escalate to levels which could be harmful to marine animals, such as whales, and negatively impact our pristine oceans.

Humans are inherently emotional and to better understand them, robots need to recognize emotions from human speech. Due to the complexity of auditory perception models, however, emotion recognition is a challenging task. In a new study, researchers from Japan and China design a novel feature that captures temporal and contextual information and extracts temporal variation of emotion using a parallel neural network architecture, opening doors to future applications in more complex speech analysis tasks.

The state of China's climate in 2020: Warmer and wetter again.

In almost ten per cent of myocardial infarctions, no obvious cause in the coronary artery can be found. Some of the patients are diagnosed with broken-heart syndrome, while others are left without a diagnosis. A new study from Karolinska Institutet in Sweden suggests that early magnetic resonance (MR) imaging of the heart can greatly increase the rate of diagnosis. The study has been published in the journal JACC Cardiovascular Imaging.

Limiting internet searches for investors increases stock market crash risk by 19%, a new study has found.

After a volatile weather year, scientists are finding answers as to why the past year of 2020 featured so many extreme weather and climate events in China.

Results from a retrospective observational study, reveal a 70% decline in the number of patients presenting with acute myocardial infarction (AMI) during April 2020 compared to April 2019. While the number of patients with AMI seeking care at hospitals dropped during the pandemic, those that did receive care experienced more severe symptoms because of delays in patients seeking emergency services. Findings underscore need for public education on benefit of early treatment for cardiac care.

New study presented at SCAI 2021 demonstrates HIV, mental health, obesity and substance use disorders as risk factors on most common type of heart disease in young Black patients

Whether you hanker for a hard hit of caffeine or favour the frothiness of a milky cappuccino, your regular coffee order could be telling you more about your cardio health than you think. In a world first study of 390,435 people, University of South Australia researchers found causal genetic evidence that cardio health - as reflected in blood pressure and heart rate - influences coffee consumption.

A late-breaking research presented at SCAI 2021 reveals the use of a potassium ferrate hemostatic patch (PFHP) reduces the time to hemostasis for patients receiving cardiac catherization. The findings indicate a faster approach to removing the compression band used during the procedure, without compromising safety.

Researchers at Kanazawa University examined a subset of GABA neurons in the circadian rhythm control center within the hypothalamus of the brain. They eliminated GABA signaling of vasopressin-producing neurons only in mice and found that it impaired circadian behavior. Specifically, time spent being active increased every day. Analysis showed a timing mismatch between the center's molecular clock and the behavior. Thus, GABA signaling is required to make sure the timing remains in sync.
