Swimming robots play a crucial role in mapping pollution, studying aquatic ecosystems, and monitoring water quality in sensitive areas such as coral reefs or lake shores. However, many devices rely on noisy propellers, which can disturb or harm wildlife. The natural clutter in these environments – including plants, animals, and debris – also poses a challenge to robotic swimmers. Now, researchers in the Soft Transducers Lab and the Unsteady flow diagnostics laboratory in EPFL’s School of Engineering, and at the Max Planck Institute for Intelligent Systems, have developed ...

The successful development of sustainable georesources for the energy transition is a key challenge for humankind in the 21st century. Hydrogen gas (H2) has great potential to replace current fossil fuels while simultaneously eliminating the associated emission of CO2 and other pollutants. However, a major obstacle is that H2 must be produced first. Current synthetic hydrogen production is at best based on renewable energies but it can also be polluting if fossil energy is used. The solution may be found ...

University of Pittsburgh School of Medicine and UPMC Hillman Cancer Center scientists have discovered a novel subset of cancer-fighting immune cells that reside outside of their normal neighborhood – known as the tertiary lymphoid structure – where they become frustratingly dysfunctional when in close contact with tumors. Described today in the journal Science Translational Medicine, the finding gives oncologists a new target for developing immunotherapies: double negative memory B cells, so-called because they are negative for two markers found on the surface of their more common brethren. They may also be a useful diagnostic ...

Humans have appreciated the beauty of flowers for centuries. Yet, flowers aren’t just aesthetically pleasing. They also play a crucial role in plant reproduction. In all plants, a well-studied gene with a curious name, Unusual Floral Organs (UFO), orchestrates the flowering process. UFO expression hinges on another complex process called cis-regulation. And this one has remained a “black box” of plant biology research for years. Now, using CRISPR gene editing, Cold ...

PHILADELPHIA – Cancer patients spend a lot of time on their care. Meeting with doctors and other members of their health care team, getting labs and other tests, picking up prescriptions, and undergoing treatment all takes time. So does getting to and from each appointment, sitting in the waiting room between each appointment, and so on. In recent years, cancer researchers have worked to quantify the level of “time toxicity” or time spent commuting to, waiting for, and receiving cancer treatment. Now, for the first time, a pilot study has shown it’s possible to use digital technology to safely ...

A multi-national, multi-institutional study led by Weill Cornell Medicine investigators found little natural resistance to a new HIV therapy called lenacapavir in a population of patients in Uganda.

There are currently around 275,000 glaciers worldwide, in which huge quantities of fresh water are stored. But this reservoir is increasingly shrinking. Since the turn of the millennium, glaciers around the world – i.e. ice masses on land excluding the Greenland and Antarctic ice sheets – have lost around 273 billion tonnes of ice per year. This corresponds to about five and a half times the volume of Lake Constance. Overall, the world’s glaciers have lost around five per cent of their total volume since the year 2000. This is the conclusion reached by an international research team of which Tobias Bolch from the Institute of Geodesy ...

A three-year effort to encourage California prosecutors to reconsider the sentences given to some people in state prison has resulted in a modest number of people being resentenced, but improvements are needed to speed review of more cases, according to a new RAND report.   During the project involving nine counties, more than 1,100 cases received an initial review. After comprehensive reviews by county district attorneys for the suitability for resentencing, 227 individuals eventually received new sentences and 174 of those offenders had been released ...

Propane dehydrogenation (PDH), as an efficient catalytic production process to obtain propylene, has developed rapidly in recent years. Previous studies have shown that zirconia exhibited excellent performance in the PDH, with the coordination-unsaturated zirconium (Zrcus) around the oxygen vacancy being the active site in the reaction. However, the critical role of oxygen vacancy is still remaining elusive, and lacked a rationale to establish a relation between structure and performance. Moreover, the strong binding of propene and hydrogen molecules shadowed ...

CHAMPAIGN, Ill. — A genetic mutation found in two human patients with schizophrenia also increased schizophrenia-related behaviors in mice with the same mutation, a rare finding of a direct genetic link to psychosis, report researchers at the University of Illinois Urbana-Champaign and colleagues in Massachusetts and Germany. The mutation increases levels of glycine decarboxylase, or GLDC, an enzyme responsible for regulating glycine in the brain. Glycine activates receptors for the neurotransmitter glutamate, called NDMA receptors. “The genetics of schizophrenia is very complex, and it ...
