Assessing regulatory fairness through machine learning

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.

Scientists discover structural changes in adult mice brains as seen in young animals

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,...

These sea slugs sever their own heads and regenerate brand-new bodies

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...

Sea level rise up to four times global average for coastal communities

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...

New method could democratize deep learning-enhanced microscopy

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.

'Island of Rats' recovers

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.

Novel hydrogen fuel purification membrane paves the way for greener future

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.

New inhibitor found to combat drug-resistant cancer cells

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.

90% of young women report using a filter or editing their photos before posting

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...
