Published Chemical analyses find hidden elements from renaissance astronomer Tycho Brahe's alchemy laboratory



Danish Tycho Brahe was most famous for his contributions to astronomy. However, he also had a well-equipped alchemical laboratory where he produced secret medicines for Europe's elite.
Published Nitrogen emissions have a net cooling effect: But researchers warn against a climate solution



An international team of researchers has found that nitrogen emissions from fertilizers and fossil fuels have a net cooling effect on the climate. But they warn increasing atmospheric nitrogen has further damaging effects on the environment, calling for an urgent reduction in greenhouse gas emissions to halt global warming.
Published Ancient marine animal had inventive past despite being represented by few species



Brachiopods were evolving in new directions but this did not turn into evolutionary success in terms of the numbers of species, researchers have found.
Published Exploring consciousness with eureka moments



We all know what it's like when the penny suddenly drops. Animals too experience such moments of insight. They could prove useful for research of consciousness.
Published Rock art and archaeological record reveal humans' complex relationship with Amazonian animals



Rock art explored by archaeologists in the Colombian Amazon has provided an insight into the complex relationship between the earliest settlers on the continent and the animals they encountered.
Published Solar absorption by black carbon in fire clouds quantified



Aerosol scientists quantify the extent of light absorption by black carbon in fire clouds to better model climate impacts of extreme wildfire events.
Published Artificial blood vessels could improve heart bypass outcomes



3D-printed blood vessels, which closely mimic the properties of human veins, could transform the treatment of cardiovascular diseases. Strong, flexible, gel-like tubes -- created using a novel 3D printing technology -- could improve outcomes for heart bypass patients by replacing the human and synthetic veins currently used in surgery to re-route blood flow, experts say.
Published In clinical trial, fecal matter transplant helped half of patients with gastrointestinal cancers overcome resistance to immunotherapy treatment



Findings from a small, proof-of-concept clinical trial have suggested that fecal microbiota transplants (FMTs) can boost the effectiveness of immunotherapy in a range of gastrointestinal cancers. In the study, six of 13 patients who had previously shown resistance to immune checkpoint inhibitors benefited from receiving FMTs from donors who had previously responded to treatment. The investigators also identified specific strains of bacteria associated with better or worse responses to FMT and immune checkpoint drugs.
Published Great Salt Lake a significant source of greenhouse gas emissions



Newly announced research examining greenhouse gas emissions from the drying lake bed of Great Salt Lake, Utah, calculates that 4.1 million tons of carbon dioxide and other greenhouse gases were released in 2020. This research suggests that drying lake beds are an overlooked but potentially significant source of greenhouse gases, which may further increase due to climate change.
Published A recipe for zero-emissions fuel: Soda cans, seawater, and caffeine



Engineers discovered that when the aluminum in soda cans is purified and mixed with seawater, the solution produces hydrogen -- which can power an engine or fuel cell without generating carbon emissions. The reaction can be sped up by adding caffeine.
Published Better way to produce green hydrogen



Researchers have developed a material that shows a remarkable ability to convert sunlight and water into clean energy.
Published Tackling industrial emissions begins at the chemical reaction



Researchers are proposing a new way to curb industrial emissions, by tapping into the 'atomic intelligence' of liquid metals to deliver greener and more sustainable chemical reactions.
Published Spin qubits go trampolining



Researchers have developed somersaulting spin qubits for universal quantum logic. This achievement may enable efficient control of large semiconductor qubit arrays. The research group recently published their demonstration of hopping spins and somersaulting spins.
Published Seven steps to achieving the right to clean indoor air post-pandemic



Seven lessons learned from the COVID-19 pandemic about ventilation's crucial role in preventing the spread of airborne pathogens has been set out in a new article.
Published Researchers develop innovative battery recycling method



A research team is tackling the environmental issue of efficiently recycling lithium ion batteries amid their increasing use.
Published It's got praying mantis eyes



The praying mantis is one of the few insects with compound eyes and the ability to perceive 3D space. Engineers are replicating their visual systems to make machines see better.
Published Foam fluidics showcase lab's creative approach to circuit design



Engineers have shown that something as simple as the flow of air through open-cell foam can be used to perform digital computation, analog sensing and combined digital-analog control in soft textile-based wearable systems.
Published New groups of methane-producing organisms in Yellowstone



The team verified that microbes found in Yellowstone National Park hot springs produce methane to grow.
Published Dark matter flies ahead of normal matter in mega galaxy cluster collision



Astronomers have untangled a messy collision between two massive clusters of galaxies in which the clusters' vast clouds of dark matter have decoupled from the so-called normal matter.
Published Hens blush when they are scared or excited, study finds



Hens fluff their head feathers and blush to express different emotions and levels of excitement, according to a new study.
