Sex with robots: How should lawmakers respond?

Advancements in technology have resulted in the design of hyper–realistic, Wi-Fi–connected, programmable sex robots that can mimic human responses, but what do these developments mean for how we regulate interactions with "sexbots" in the future?

Shielding ultracold molecules with microwaves

Ultracold molecules are promising for applications in new quantum technologies. Unfortunately, these molecules are destroyed upon colliding with each other. Researchers at Harvard University, MIT, Korea University and Radboud University have demonstrated that these collisional losses can be prevented by guiding the interaction between molecules using microwaves in such a way that they repel each other and, therefore, do not come close to each other during collisions. Their paper will be published in Science on 13 August.

Material and coating process to protect ceramic parts

Post-pandemic vacation travel was among the biggest stories of summer 2021, raising questions about air travel's contribution to greenhouse gas emissions and climate change. According to the Environmental and Energy Study Institute, 710 million tons of global carbon dioxide came from commercial aviation in 2013. By 2017, that number reached 860 million tons, a 21% increase in four years. By 2018, it climbed to 905 million tons, 2.4% of total CO2 emissions.

New evidence about Roman Britain executions revealed

King's research has helped uncover new evidence showing the portrayal of the execution of captives in the arena by throwing them to lions. The evidence follows the discovery of an elaborately-decorated Roman bronze key handle.

Humans aren't the only species whose metabolisms tend to slow down with age

If you feel like your metabolism just isn't what it used to be, no matter how many hours you spend in the gym, dolphins can relate.

Microbial study reveals extended lifespan of starved bacteria

A study of microbial populations under a prolonged period of starvation by Indiana University professor Jay T. Lennon and his laboratory could help researchers answer questions pertaining to chronic infections, the functioning of bacteria in the environment and the persistence of life itself.

Neutrons help measure cell membrane viscosity—and reveal its basis

We now have a clearer picture of the lightning-fast molecular dance occurring within the membrane that encloses each cell in our body, revealed in part by neutron beams at the National Institute of Standards and Technology (NIST). The findings may have applications in drug development, and they also address long-standing fundamental mysteries about why cell membranes move as they do.

Dog coat patterns have ancient origin

Dogs come in all shapes and sizes, but variations in color patterns provide some of their most distinctive characteristics. A newly released study sheds light on a subset of these patterns, unexpectedly leading to new questions about long-held tenets of dog evolution.

Heat transfer experiment arrives at International Space Station

People who design spacecraft must prioritize two factors: reducing weight and managing extreme temperatures.

New algorithm can help improve cellular materials design

New research published in Scientific Reports has revealed that a simple but robust algorithm can help engineers to improve the design of cellular materials that are used in a variety of diverse applications ranging from defense, bio-medical to smart structures and the aerospace sector.

500 million measurements on the impact of climate change

It is the most comprehensive study of its kind to date. Researchers at the University of Bonn and the University of South-Eastern Norway have studied how two characteristic arctic-alpine plant species respond to global warming. They did this by analyzing almost 500 million of their own readings from the mountainous region of Norway. The analyses show that potential consequences of climate change are extremely dependent on the specific location of the plants and that deciduous species in particular will benefit from warming. The result would be a further increase in the trend toward greening of the arctic-alpine regions. The study is published in the journal Ecosphere.

New study shows the potential of DNA-based data-structures systems

Newcastle University research offers important insights into how we could turn DNA into a green-by-design data structure that organises data like conventional computers.

Why boiling droplets can race across hot oily surfaces

When you're frying something in a skillet and some droplets of water fall into the pan, you may have noticed those droplets skittering around on top of the film of hot oil. Now, that seemingly trivial phenomenon has been analyzed and understood for the first time by researchers at MIT—and may have important implications for microfluidic devices, heat transfer systems, and other useful functions.

Greece fires under control as reconstruction begins

Fires burning for over a week that caused Greece's worst ecological disaster in decades were finally placed under control Friday, the fire department said.

Tens of thousands urged to evacuate as heavy rain hits Japan

Tens of thousands of people were urged to evacuate on Friday as "unprecedented" levels of torrential rain hit western Japan, raising the risk of floods and landslides, the weather agency said.

Turkey's flash floods death toll soars to 27

The death toll from Turkey's flash floods soared to 27 on Friday as President Recep Tayyip Erdogan prepared to inspect one of the hardest-hit regions and lend his moral support.

Gates offers $1.5 bn in climate help if US takes legislative action

Microsoft co-founder Bill Gates on Thursday said his climate fund would pour $1.5 billion into projects with the United States if the government enacts a program to cut carbon emissions currently working its way through Congress.

Boeing Starliner launch faces further delays

Boeing's troubled Starliner spaceship could be set for further delays after the company said Thursday it was working to solve problems with the propulsion system.

Fires charring range set up ranchers for hardship in US West

Wildfires tearing through Montana and elsewhere in the U.S. West are devouring vast rangeland areas that cattle ranchers depend upon, setting the stage for a potential shortage of pasture as the hot, dry summer grinds on.

21 dead as torrential rainfall batters central China

At least 21 people died as heavy downpours struck central China's Hubei province, authorities said Friday, weeks after record floods wreaked havoc and killed hundreds in a neighbouring province.

Climate-fueled wildfires take toll on tropical Pacific isles

A metal roof sits atop the burned remains of a homestead on the once-lush slopes of Hawaii's Mauna Kea—a dormant volcano and the state's tallest peak—charred cars and motorcycles strewn about as wind-whipped sand and ash blast the scorched landscape.

Black howler monkeys adapt mental maps like humans

Ever since humans began committing their view of the world to flat slabs of rock and papyrus, we had a sense that our mental maps are laid out in much the same way. However, our mental maps are nothing like paper maps. Humans rely on route-based maps. These internal maps, also used by animals, are composed of well-trodden routes linking frequently visited locations, with little understanding of where these routes lie relative to one another. Yet, humans are able to supplement these rudimentary representations with knowledge of the distances we cover and direction to take occasional short-cuts. Yet many creatures negotiate far more complex environments and need to navigate efficiently, so being able to combine knowledge of separate routes to take short cuts would be useful. Can other animals navigate like humans?

Farmers help create 'Virtual safe space' to save bumblebees

Solutions to help pollinators can be tested using a "virtual safe space" tool created by scientists at the University of Exeter in collaboration with farmers and land managers.
