Teaching artificial intelligence to connect senses like vision and touch

In Canadian author Margaret Atwood's book The Blind Assassin, she says that "touch comes before sight, before speech. It's the first language and the last, and it always tells the truth."

Researchers use biological evolution to inspire machine learning

As Charles Darwin wrote in at the end of his seminal 1859 book On the Origin of the Species, "whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved." Scientists have since long believed that the diversity and range of forms of life on Earth provide evidence that biological evolution spontaneously innovates in an open-ended way, constantly inventing new things. However, attempts to construct artificial simulations of evolutionary systems tend to run into limits in the complexity and novelty which they can produce. This is sometimes referred to as "the problem of open-endedness." Because of this difficulty, to date, scientists can't easily make artificial systems capable of exhibiting the richness and diversity of biological systems.

SPFCNN-Miner: A new classifier to tackle class-unbalanced data

Researchers at Chongqing University in China have recently developed a cost-sensitive meta-learning classifier that can be used when the training data available is high-dimensional or limited. Their classifier, called SPFCNN-Miner, was presented in a paper published in Elsevier's Future Generation Computer Systems.

Study predicts more long-term sea level rise from Greenland ice

Greenland's melting ice sheet could generate more sea level rise than previously thought if greenhouse gas emissions continue to increase and warm the atmosphere at their current rate, according to a new modeling study. The study, which used data from NASA's Operation IceBridge airborne campaign, was published in Science Advances today. In the next 200 years, the ice sheet model shows that melting at the present rate could contribute 19 to 63 inches to global sea level rise, said the team led by scientists at the Geophysical Institute at the University of Alaska Fairbanks. These numbers are at least 80 percent higher than previous estimates, which forecasted up to 35 inches of sea level rise from Greenland's ice.

Ethics of AI: how should we treat rational, sentient robots – if they existed?

Imagine a world where humans co-existed with beings who, like us, had minds, thoughts, feelings, self-conscious awareness and the capacity to perform purposeful actions—but, unlike us, these beings had artificial mechanical bodies that could be switched on and off.

Finding 'Nemo's' family tree of anemones

Thanks in part to the popular film Finding Nemo, clownfishes are well known to the public and well represented in scientific literature. But the same can't be said for the equally colorful sea anemones—venomous, tentacled animals—that protect clownfishes and that the fish nourish and protect in return. A new study published online this month in the journal Molecular Phylogenetics and Evolution takes a step to change that, presenting a new tree of life for clownfish-hosting sea anemones along with some surprises about their taxonomy and origins.

Researchers see around corners to detect object shapes

Computer vision researchers have demonstrated they can use special light sources and sensors to see around corners or through gauzy filters, enabling them to reconstruct the shapes of unseen objects.

Early research shows a way to develop effective therapies against pancreatic cancer

Pancreatic ductal adenocarcinoma (PDAC), the most common form of pancreatic cancer, is the fifth most common cause of death from cancer in the UK and the third in the United States. Deaths from PDAC outnumber those from breast cancer despite the significant difference in incidence rates.

Medicare program aimed at lowering costs, improving care may not be working as well as thought

As the Medicare system seeks to improve the care of older adults while also keeping costs from growing too fast, a new University of Michigan study suggests that one major effort may not be having as much of an impact as hoped.

Good physical fitness in middle age linked to lower chronic lung disease risk

Good heart and lung (cardiorespiratory) fitness in middle age is associated with a lower long term risk of chronic lung disease (COPD), suggests Danish research published online in the journal Thorax.

Unexpected culprit—wetlands as source of methane

Wetlands are an important part of the Earth's natural water management system. The complex system of plants, soil, and aquatic life serves as a reservoir that captures and cleans water. However, as cities have expanded, many wetlands were drained for construction. In addition, many areas of land in the Midwest were drained to increase uses for agriculture to feed a growing world.

Applying active inference body perception to a humanoid robot

A key challenge for robotics researchers is developing systems that can interact with humans and their surrounding environment in situations that involve varying degrees of uncertainty. In fact, while humans can continuously learn from their experiences and perceive their body as a whole as they interact with the world, robots do not yet have these capabilities.

Size matters: New data reveals cell size sparks genome awakening in embryos

Transitions are a hallmark of life. When dormant plants flower in the spring or when a young adult strikes out on their own, there is a shift in control. Similarly, there is a transition during early development when an embryo undergoes biochemical changes, switching from being controlled by maternal molecules to being governed by its own genome. For the first time, a team from the Perelman School of Medicine at the University of Pennsylvania found in an embryo that activation of its genome does not happen all at once, instead it follows a specific pattern controlled primarily by the various sizes of its cells. The researchers published their results this week as the cover story in Developmental Cell.
