Evolutionary arms races between marine animals overhauled ocean ecosystems on scales similar to the mass extinctions triggered by global disasters, a new study shows.

Applying machine learning to a U.S. Environmental Protection Agency initiative, researchers reveal how key design elements determine what communities bear the burden of pollution. The approach could help ensure fairness and accountability in machine learning used by government regulators.

Squids' remarkable ability to tune both the color and the brightness of their iridescence comes down to a subtle but powerful mechanism.

A psychology researcher finds that people who express moral outrage, and act on their convictions, are more attractive as long-term mates.

An analysis of several large studies involving participants from more than 60 countries has found that eating oily fish regularly can help prevent cardiovascular disease (CVD) in high-risk individuals, such as those who already have heart disease or stroke.

A new study from the University of California, Irvine shows that compounds in both green and black tea relax blood vessels by activating ion channel proteins in the blood vessel wall. The discovery helps explain the antihypertensive properties of tea and could lead to the design of new blood pressure-lowering medications.

Vega, one of the brightest stars in the night sky, may play host to a giant planet with average surface temperatures of 5,390 degrees Fahrenheit.

A new study to detect calcification stress before and across ancient ocean acidification events.

A global observation of an ongoing atmospheric drying -- known by scientists as a rise in vapor pressure deficit -- has been observed worldwide since the early 2000s. In recent years, this concerning phenomenon has been on the rise, and is predicted to amplify even more in the coming decades as climate change intensifies.

A new type of CAR T-cell therapy more than triples the expected length of remission for multiple myeloma patients who have relapsed several times, according to an international clinical trial.

Understanding cellular and molecular mechanisms underlying brain 'plasticity' is crucial for explaining many illnesses and conditions. Neurocientists managed to repeatedly image synapses, tiny contact sites between neurons, in awake adult mice. They are the first to discover that adult neurons in the primary visual cortex with an increased number of 'silent synapses' lacking a certain protein,...

The public doesn't need to know how Artificial Intelligence works to trust it. They just need to know that someone with the necessary skillset is examining AI and has the authority to mete out sanctions if it causes or is likely to cause harm.

A deep-learning algorithm developed by researchers is designed to help machines navigate in the real world, where imperfect or 'adversarial' inputs may cause uncertainty.

The process retains properties of fibers at a higher rate than previous methods, demonstrating a retention strength of up to 90 percent. Recycling of composite materials could be up to 70 percent cheaper and lead to a 90-95 percent reduction in CO2 emissions compared to standard manufacturing.

What is the origin of black holes and how is that question connected with another mystery, the nature of dark matter? Dark matter comprises the majority of matter in the Universe, but its nature remains unknown.

You've heard of animals that can lose and then regenerate a tail or limb. Scientists have discovered two species of sacoglossan sea slug that can do even better, shedding and then regenerating a whole new body complete with the heart and other internal organs. The researchers also suggest that the slugs may use the photosynthetic ability of chloroplasts they incorporate from the algae in their...

New research shows that coastal populations are experiencing relative sea-level rise up to four times faster than the global average. The study is the first to analyze global sea-level rise combined with measurements of sinking land. The impacts are far larger than the global numbers reported by the Intergovernmental Panel on Climate Change (IPCC). The high rates of relative sea-level rise are...

Deep learning is a potential tool for scientists to glean more detail from low-resolution images in microscopy, but it's often difficult to gather enough baseline data to train computers in the process. Now, a new method developed could make the technology more accessible -- by taking high-resolution images, and artificially degrading them.

Researchers combined machine learning with knowledge gained from experiments and equations guided by physics to discover and explain a process that shortens the lifetimes of fast-charging lithium-ion batteries.

A coordinated conservation effort that removed rats from Hawadax Island, formerly known as 'Rat Island,' has become a new example of how ecosystems can fully recover to their natural state in little more than a decade.

Hydrogen is a clean source of fuel, but its purification has been challenging until now. Now, a group of scientists has found a solution -- by characterizing a hybrid separation membrane for purifying hydrogen from other gases. In light of the current global warming crisis, the scientists are optimistic that their novel membrane will make the use of hydrogen fuel efficient and cost-effective.

Researchers demonstrated that college students possessing a higher degree of resilience were less susceptible to burnout and psychological distress. By identifying learnable components of resilience, the study points to concrete ways that young adults can learn this vital characteristic, resulting in better mental health outcomes.

A new substance could improve the treatment of persistent cancers. Researchers have developed a new inhibitor that makes drug-resistant tumor cells respond again to chemotherapy. The new substance blocks a protein in the cancer cells that normally transports the cancer drugs back out of the cells.

Ninety per cent of women report using a filter or editing their photos before posting to even out their skin tone, reshape their jaw or nose, shave off weight, brighten or bronze their skin or whiten their teeth. Young women in the study also described regularly seeing advertisements or push notifications for cosmetic procedures -- particularly for teeth whitening, lip fillers, and surgery to...
