Rock samples from the Jezero crater analysed by the Perseverance rover show evidence of liquid water and signatures that could be organic compounds. A study published in Science analyses multiple rocks found at the bottom of Jezero Crater on Mars, where the Perseverance rover landed in 2020, revealing significant interaction between the rocks and liquid water.

Low-traffic neighbourhoods (LTNs) reduce traffic and air pollution without displacing the problem to nearby streets, new research has shown. The study by researchers at Imperial College London looked at three LTNs in London, to identify their impact on both air pollution and traffic within the LTN zones and in the surrounding area.

Studies of one exoplanet's atmosphere using James Webb Space Telescope instruments have revealed the detection of new molecules and cloud structures. In a suite of studies across five papers, a large international team including Imperial College London researchers has demonstrated the power of the James Webb Space Telescope (JWST) for investigating exoplanets.

Here's a batch of fresh news and announcements from across Imperial. From research into how ions behave in fusion reactions, to a study on why some people develop scar tissue in their lungs following severe COVID-19 infection, here is some quick-read news from across the College. Fusion surprises Ions may behave differently in fusion reactions than previously expected, providing important insights for the future design of a laser-fusion energy source.

Researchers did not detect any SARS-CoV-2 in Thames water after raw sewage discharge, suggesting it is unlikely to be a route of transmission. SARS-CoV-2, the virus responsible for COVID-19, has been detected in wastewater and can be used to track outbreaks in populations. This has led researchers to question whether wastewater can also be a source of disease transmission.

New research has found variable voltages in the membranes of breast cancer cells, revealing clues about how they grow and spread. The research, led by Imperial College London and The Institute of Cancer Research, London , could help us better understand how cancer cells 'decide' when to multiply and where to spread to.

Researchers have created a laser system based on a network like a spider's web, which can be precisely controlled to produce different light colours. The system, invented by a team led by researchers at Imperial College London with partners in Italy and Switzerland, could be used in new sensing and computing applications.

Imperial scientists have shared how working directly with mountain communities could drive adaptation to the loss of their main water sources. Nearly two billion people globally rely on mountain water for drinking and irrigation, but this water source is under threat due to global heating. Mountainous regions are particularly impacted by the effects of the climate crisis , with melting glaciers and snow adding to water scarcity in regions such as the Himalayas, Central Asia, and Andes.

Imperial and chemical company BASF will reveal new techniques for optimising experimental design at leading machine learning conference NeurIPS. Three papers outlining new machine learning techniques that address important needs in the chemical industry have been judged ground-breaking enough to win acceptance at the NeurIPS conference, one of the most competitive international venues for research in machine learning.

An Imperial-developed tiny microscope that can be steered through small bodily spaces during surgery has entered its next phase of laboratory trials. The endo-microscope - a microscope designed to be inserted into the body to provide views of tissue and organs - produces images with unprecedented speed.

Here's a batch of fresh news and announcements from across Imperial. From materials research that could help with the development of low-power next-generation technologies, to the discovery of a biological pathway that may explain the underlying mechanisms of Alzheimer's disease, here is some quick-read news from across the College.

NASA instruments have detected a Mars meteoroid impact that left a crater one and a half times the size of Trafalgar Square. It is the largest crater-forming impact ever observed in the solar system. The van-sized space rock weighed 200 tonnes and produced a blast zone around the crater equivalent in size to the area inside London's M25 motorway.

An unexpected river under the Antarctic ice sheet affects the flow and melting of ice, potentially accelerating ice loss as the climate warms. The 460km-long river is revealed in a new study, which details how it collects water at the base of the Antarctic ice sheet from an area the size of Germany and France combined.

Researchers have devised a cheaper, more efficient, and sustainable way to produce a breast cancer drug in South Africa. The method is designed to facilitate the development of local pharmaceutical manufacturing capabilities in South Africa that could serve the country and its neighbours. We were able to find a more efficient way to manufacture lapatinib..

A new method to study the proteins released by cells could lead to the development of new tools to track diseases including cancer. The method for finding new 'biomarker' proteins was developed by scientists at the Francis Crick Institute and Imperial College London. Biomarkers are highly valuable tools that allow doctors to study biology and disease.

Imperial College London scientists have successfully placed a bioinspired steerable catheter into the brain of an animal for the first time. The early-stage research tested the delivery and safety of the new implantable catheter design in two sheep to determine its potential for use in diagnosing and treating diseases in the brain.

Five teams of undergraduate students have had the opportunity to develop impactful new technologies in Imperial labs this summer. The Faculty of Natural Sciences' Make A Difference (FoNS-MAD) competition, which is open to all undergraduate students from across the College, gives students the resources to develop low-cost technologies that will have a positive impact on society.

A new analysis by an Imperial researcher for WWF shows krill play a vital role in keeping carbon out of the atmosphere. The analysis, conducted by Dr Emma Cavan from the Department of Life Sciences (Silwood Park) at Imperial, suggests krill should be valued beyond their worth as a fished resource. Life on Earth clearly has an important role in carbon cycling and sequestration.

Researchers have created a machine learning tool that can help identify patients who are most at risk of developing COVID-19 while in hospital. The tool, which is a form of artificial intelligence (AI), was able to predict patients at high risk of developing COVID-19 with 87 per cent accuracy in a study.

Researchers have programmed bacterial cells to react to changes in light and temperature with the help of synthetic cell machinery. The innovation is a step forward for the field of cell engineering - a discipline which works to alter and harness the power of biological cells for potential applications in medicine, biomanufacturing, and biosensing.
