Deliveroo appoints Goldman Sachs to oversee London float

first_img However, further banks are expected to join discussions in the coming months. whatsapp It comes as the food delivery giant saw sales rocket during the pandemic, as a nationwide lockdown and social distancing measures forced customers to eat from home. The group last week announced it is preparing to add an extra 15,000 riders to its fleet by the end of the year to meet fresh partnerships and a surge in demand. Deliveroo declined City A.M’s requests to comment on Goldman’s appointment, and it is understood that there is no definitive timetable for a public listing.  In June, the CMA gave Amazon the green light to pump £442m into the food delivery company, after Deliveroo warned the watchdog that the “impact of the coronavirus pandemic on its business meant that it would fail financially and exit the market without the Amazon investment”. Deliveroo now has an estimated 44,000 restaurants and 16 grocery partnerships on its platform in the UK, including supermarket giants Waitrose, Morrison’s Aldi and the Coop. Poppy Wood Deliveroo has appointed Goldman Sachs to oversee its long-awaited London flotation, according to reports, in a move that would value the UK food delivery company at more than £2bn.

The nationwide lockdown came as a welcome boost for the food delivery company, after it last year struggled to turn a profit. Last September, Deliveroo said losses had deepened from £199m to £232m in 2018.

News / Atlanta cargo community system blazes a high-tech trail in the US

first_img“Gone are the days of contacting multiple agencies to locate a status update on your shipment, as the ATL ACS is your new single resource for all progress reports on your moving products,” said Sonny Trawick, international quality assurance manager of R&L Global Logistics.Elliott Paige, director of air services development of the airport, a driving force behind the establishment of a CCS at Atlanta, said that until now drivers coming to the airport to pick up freight had not known how much freight they would be able to collect, having had no visibility into the availability of shipments. They would often spend long times waiting and occasionally leave the airport without a single shipment, he said.The ACS has a feature that allows truckers to book dock doors. For their part, handlers can give their approval electronically or decline, giving reasons, such as outstanding payments. The system is linked with PayCargo, allowing users to pay on the spot.In developing the platform, Kale has worked with Microsoft to incorporate artificial intelligence and machine learning in the system. It can predict, assign and prioritise the allocation of docks for trucks waiting at the marshalling yard.As it is being used, the system builds up data and begins to learn the behaviour of the individual users. Over time, this will enable it to give advice to improve efficiency, such as suggesting a better pick-up time or proposing an alternative route, Mr Paige said.Down the road, he envisages Atlanta’s ACS to connect with community platforms at other airports, such as Amsterdam Schiphol, which has a partnership agreement with Atlanta to develop a tradelane.He is also looking to bring customs into the fold. The US Customs & Border Protection Agency (CBP) has shown interest in the platform, but Mr Paige does not expect a link to materialise soon. As a federal agency, CBP would not engage just with Atlanta but go for a nationwide approach with links to multiple community systems, he said.“We’ll start with the private sector. They are a lot more nimble,” he added.While the airport authority has pushed the ACS project, it has not invested in it. ACS is a private, commercial initiative. To date it has not charged for use of the platform, but early in the coming year it will come up with a fee structure, Mr Paige said.The airport authority is pursuing another avenue for cargo development. It has put up an RFI for the development of a 63-acre parcel of land on the south side of the airport. It has no specific plans for the type of cargo facility to be built other than wanting a state-of-the-art building capable of handling different kinds of cargo relevant to the region, that can move freight at the speed of baggage, Mr Paige said. © Alexey Novikov The first air cargo community system in the US in the 21st century is officially open for business.The Airport Cargo Community System (ACS), a digital platform developed and managed by logistics IT provider Kale Logistics, enables all participating stakeholders at Atlanta’s Hartfield Jackson International Airport to communicate with each other to facilitate the movement of goods and information at the airport.After trials that had kicked off in the summer, with some 20 stakeholders, the system went live on 14 November.According to Kale, ACS is meant to be more than a simple data-sharing platform with a fully functional digital system that eliminates duplicate data entry work and excessive documentation, addresses truck congestion and wait time issues and offers the transparency to reduce overall logistics costs and enable better supply chain planning.center_img By Ian Putzger, Americas correspondent 18/12/2019last_img read more

How a blood test changed my life and helped me become a rare disease advocate

Can this scientist save herself? About the Author Reprints What made it so difficult was the feeling of isolation. I no longer felt like I belonged to the world of the able-bodied. Worse, I didn’t know anyone who truly understood my situation.After growing tired of sulking, I slowly picked myself up. I decided to focus on what this disease could not take away from me. One event that helped me was a conference I attended in 2013 sponsored by the Jain Foundation — an organization whose mission is to find a cure for my disease. There I finally met other people with dysferlinopathy.It was an uplifting experience, one that I wish happened years earlier. These people got it — they knew what it felt like to go from ability to disability right when the whole world was finally at your fingertips. I didn’t have to explain to them what I was feeling; they understood just through eye contact and a handshake. First OpinionHow a blood test changed my life and helped me become a rare disease advocate The rest of that year, my senior year of high school, was a long, frustrating diagnostic odyssey. It took 10 months to confirm I had dysferlinopathy. I thought it was an odd diagnosis, since I felt perfectly healthy and loved to play basketball.Since there aren’t any treatments for dysferlinopathy, it was only a matter of time before symptoms appeared. When they did, announcing the appearance of the disease with fatigue and falls, my life dissolved into turmoil. The physical challenges were formidable, but the mental challenges were often worse. I suffered from panic attacks and fell into a deep depression.advertisement Kathy Giusti: The businesswoman who took on her own cancer Tags dysferlinopathymuscular dystrophyrare diseases Being an advocate for my disease has pushed me toward a career in health care. One goal that dysferlinopathy could not take away from me was to get my MBA. I’m now enrolled in the graduate school of management at Boston College, graduating in May. It is not the easiest campus to navigate with a muscle disease, but I am not letting logistics get in the way of my goals.Over the years, I have met many other people who are living with rare diseases of their own. No one wants to be in this club. But once you are ready to accept membership, I’ve found that there is a community out there who will embrace you with open arms.On Monday I’m marking Rare Disease Day by speaking at a ceremony at the Massachusetts State House.

My body has trouble making a protein called dysferlin, which is needed to build and repair muscle tissue.

A pickup truck plowed into the passenger side of my friend’s car, where I was sitting. Somehow, I emerged uninjured.

New CU-NASA Research Belies Previous Idea That Mars Was Once Warm, Wet Planet

first_imgA new study led by University of Colorado at Boulder researchers indicates Mars has been primarily a cold, dry planet following its formation some 4 billion years ago, making the possibility of the evolution of life there challenging at best. Led by CU-Boulder doctoral candidate Teresa Segura and her adviser, Professor Owen B. Toon, the team used Mars photos and computer models to show that large asteroids or comets hit the planet some 3.5 billion years ago. These impacts apparently occurred about the time major river channels were formed on the Red Planet, said Segura. According to the available evidence, roughly 25 huge impactors, each about 60 miles to 150 miles in diameter, slammed into Mars roughly every 10 million to 20 million years during the period, blowing a volume of debris equivalent to a global blanket hundreds of yards thick into the atmosphere. The material is believed to have melted portions of subsurface and polar ice, creating steam and scalding water that rained back on Mars at some six feet per year for decades or centuries, causing rivers to form and flow, according to the study. But the study belies the warm, wet, Mars theory of rivers and oceans embraced by many planetary scientists, since such impactors were so infrequent. “There apparently were some brief warm and wet periods on Mars, but we believe that through most of its history, Mars has been a cold, dry planet,” said Segura, currently a visiting researcher at NASA-Ames in California. A paper by Segura, Toon, CU-Boulder graduate Anthony Colaprete — now at NASA-Ames — and Kevin Zahnle of NASA-Ames, will appear in the Dec. 6 issue of Science. “When the river valleys on Mars were confirmed in the 1970s, many scientists believed there once was an Earth-like period with warmth, rivers and oceans,” said Toon, director of CU-Boulder’s Program in Oceanic and Atmospheric Sciences and a professor at the University’s Laboratory for Astrophysics and Space Physics. “What sparked our interest was that the large craters and river valleys appeared to be about the same age.” In between such catastrophic events, the planet was likely very cold, dry and inhospitable to any life forms, said Toon. “We definitely see river valleys but not tributaries, indicating the rivers were not as mature as those on Earth.” The rare, hot rains pelting Mars that likely came from water in asteroids and comets hitting the planets and the evaporation of some ice from polar caps and ice beneath the impacts would have been spectacular, said Segura. “We believe these events caused short periods of a warm and wet climate, but overall, we think Mars has been cold and dry for the majority of its history.” According to Toon, previous theories that carbon dioxide gas and clouds warmed Mars during its early history “just have not worked out quantitatively.” There is no evidence on Mars of large limestone deposits from the first billion years, which would be directly linked to large amounts of C02, a greenhouse gas, he said. There also is no evidence that another greenhouse gas, methane — which can be created naturally by volcanic eruptions or produced by primitive life — was present in the Martian atmosphere. But even CO2 and methane combined would not be enough to warm the planet as greenhouse gases did on Earth and Venus in their early histories, Toon said. “Hypotheses of a warm, wet Mars, based on the presumption that the valley networks formed in a long-lasting greenhouse climate, imply that Mars may once have been teeming with life,” wrote the authors in Science. “In contrast, we envision a cold and dry planet, an almost endless winter broken by episodes of scalding rains followed by flash floods. “Only during the brief years or decades after the impact events would Mars have been temperate, and only then might it have bloomed with life as we know it,” they wrote. Although temperatures in the subsurface of Martian soil may have exceeded the boiling point during the impact period and provided a possible refuge for life underground, the short duration of warm periods predicted by the researchers would have made it difficult for life to ever establish itself on Mars, the team concluded.
