Seattle-based Spaceflight Inc. has signed an agreement to secure most of the payload mass on a Firefly Aerospace rocket that's due to lift off from California's Vandenberg Air Force Base in 2021. The agreement, announced today, establishes Spaceflight as the mission's anchor customer and commits the company to managing the logistics for multiple payloads on the Firefly Alpha rocket. That should help Firefly maximize use of the rocket's 630-kilogram (1,389-pound) capacity for a launch to sun-synchronous orbit. Texas-based Firefly Aerospace is planning to launch the Alpha on its maiden flight from Vandenberg later this year. The company suffered a setback in… Read More

A satellite mission that bounces laser light off the ice sheets of Antarctica and Greenland has found that hundreds of billions of tons' worth of ice are being lost every year due to Earth's changing climate. Scientists involved in NASA's ICESat-2 project report in the journal Science that the net loss of ice from those regions has been responsible for 0.55 inches of sea level rise since 2003. That's slightly less than a third of the total amount of sea level rise observed in the world's oceans over that time. To track how the ice sheets are changing, the ICESat-2… Read More

The competition will involve navigating a rover through a facsimile lava tube and surface structures, generating maps, identifying valuable resources and deploying an airtight barrier to seal the… Read More

The third time's the charm for the Allen Institute for Brain Science's 3-D atlas of the mouse brain. Version 3 of the atlas, known as the Allen Mouse Brain Common Coordinate Framework or CCFv3, is the subject of a research paper published today in the journal Cell. It builds on a partial brain map that focused on the mouse cortex and was released in 2016. Previous versions of the atlas were rendered with lower-resolution 3-D maps. The latest high-resolution maps are fine enough to pinpoint the locations of individual brain cells — which is crucial for interpreting datasets that contain thousands… Read More

The following is a brief roundup of the latest scientific studies on the novel coronavirus and efforts to find treatments and vaccines for COVID-19, the illness caused by the virus. A new antibody test is highly accurate at determining whether people have been infected with the novel coronavirus, according to a study published on Friday in The Journal of Clinical Microbiology. Researchers at the University of Washington School of Medicine found the test, manufactured by Abbott Laboratories, had a specificity rate of 99.9% and a sensitivity rate of 100%, suggesting little chance of incorrectly diagnosing a healthy person as having been infected and virtually no chance of a false negative readout.

Scientists usually find black holes by detecting X-rays they emit as they devour nearby stars. But this one was quietly hidden 1,000 light-years away.

Puzzles for kids in quarantine

Update: Solutions can now be read here.

Today’s teasers are from my new puzzle book, Football School: the Ultimate Puzzle Book, which is aimed at 8 to 13-year-olds. No pressure. I have extracted some of the problems that I thought might also provide entertainment for grown-ups.

We kick off with a problem for everyone tending their lawns, plant pots, and window boxes during lockdown.

The solutions to today’s puzzles

It is the sixth week of lockdown, and for many people things are getting progressively more intense. Most families are physically distancing at home. People are only leaving the house for their weekly shop – and spending a lot of that time waiting in the queue – or to exercise once a day.

In my family things are a bit different. Our driveway is usually empty during the day as my parents, who are doctors, go in to work. It is difficult to imagine how only some weeks ago my main worries were around my GCSEs. Now every day, I hear about deaths from coronavirus. I cannot help but feel a surge of fear for my parents as I watch these updates with my brother. I’m painfully aware of the many healthcare workers who have lost their lives.

Letter seeks to dispel view that Prof Neil Ferguson was single architect of lockdown idea

• Coronavirus – latest updates

A group of leading UK scientists have insisted that the scientific basis for the coronavirus lockdown is the work of a large group of experts, and that epidemiologist Prof Neil Ferguson is just one voice among many.

In a letter co-ordinated by Dr Thibaut Jombart, an associate professor at the London School of Hygiene and Tropical Medicine, more than 25 prominent scientists said debates after Ferguson’s “individual error” – in which he flouted lockdown rules by receiving visits at home from his lover – had amplified a misconception that he alone persuaded the government to change policy.

Sage told widespread use of antibody tests could lead to criminal behaviour, papers reveal

Downing Street’s scientific advisers feared people might intentionally seek to contract coronavirus and that a black market in fake test results could emerge if employers allowed workers to return only when they had a positive antibody test.

The Scientific Advisory Group for Emergencies, known as Sage, was warned last month by its behavioural psychology subgroup that the widespread introduction of antibody tests could lead to a range of potentially dangerous and even criminal “negative behavioural responses” if not handled well.

Black people are more than four times more likely to die from Covid-19 than white people, according to stark official figures exposing a dramatic divergence in the impact of the coronavirus pandemic in England and Wales.

The Office of National Statistics found that the difference in the virus’s impact was caused not only by pre-existing differences in communities’ wealth, health, education and living arrangements.

Ontario Premier Doug Ford dropped by his cottage last month, days after asking the province’s residents to stay away from theirs. His office says Ford "drove alone" and was there for less than an hour to check on construction.

The United Nations said a "smart strategy" is to contain coronavirus in the world's most vulnerable countries to stem a "further phase of the pandemic."

Vice President Mike Pence's press secretary has the coronavirus, the White House said Friday, making her the second person who works at the White House complex known to test positive for the virus this week. President Donald Trump, who publicly identified the affected Pence aide, said he was “not worried” about the virus spreading in the White House. Pence spokeswoman Katie Miller, who tested positive Friday, had been in recent contact with Pence but not with the president.

Hackers linked to Iran have targeted staff at U.S. drugmaker Gilead Sciences Inc in recent weeks, according to publicly-available web archives reviewed by Reuters and three cybersecurity researchers, as the company races to deploy a treatment for the COVID-19 virus. In one case, a fake email login page designed to steal passwords was sent in April to a top Gilead executive involved in legal and corporate affairs, according to an archived version on a website used to scan for malicious web addresses. Ohad Zaidenberg, lead intelligence researcher at Israeli cybersecurity firm ClearSky, who closely tracks Iranian hacking activity and has investigated the attacks, said the attempt was part of an effort by an Iranian group to compromise email accounts of staff at the company using messages that impersonated journalists.

Police have dropped an investigation into two prominent Brexit campaigners accused of breaching spending rules during the referendum campaign. In 2018 the Electoral commission said that Alan Halsall, of Vote Leave, and Darren Grimes, founder of pro-Brexit youth group BeLeave, failed to declare a payment related to the campaign. The watchdog said that BeLeave "spent more than £675,000 with (Canadian data firm) Aggregate IQ under a common plan with Vote Leave". This spending took Vote Leave over its £7 million legal spending limit by almost £500,000. Vote Leave paid a £61,000 fine, but denied wrongdoing, while Mr Grimes won an appeal against his £20,000 fine in July. The Commission also referred the pair to the Metropolitan Police but on Friday it was revealed that the investigations had now been dropped. A spokesman for the Leave campaigners said: "The Metropolitan Police has written to Vote Leave board member Alan Halsall and BeLeave founder Darren Grimes to confirm that it will not be acting on allegations made against them by the Electoral Commission and various Remain campaigners. "This marks the end of a two-year ordeal for both individuals." Mr Grimes, 26, said the development called into question whether the Electoral Commission was "fit for purpose". He had insisted since the allegations were first made that he was "completely innocent" of making false declarations in relation to the £680,000 donation. In a statement, Mr Grimes, a former fashion student originally from County Durham, said: "The Metropolitan Police has found, after investigation and consultation with the Crown Prosecution Service, that there is no case to be answered. "Once again the Electoral Commission has been found to be part of the mob, a quango out of control that isn't policing elections so much as punishing Leavers who have the temerity to win them. "My ordeal at the hands of the kangaroo court that is the Electoral Commission is now over, but questions must now be asked of whether that body is fit for purpose." Mr Halsall, the responsible person for Vote Leave, said he was "delighted to have been exonerated" and thanked the police for their "professional" investigation. "I was very disappointed that my colleagues at Vote Leave and myself were never given the opportunity of making our case in person to the Electoral Commission before being fined and reported to the police," he added. "It seems a rather unusual way of conducting an inquiry into such matters that only the so-called whistleblowers who made these allegations are interviewed by the regulator." A spokesman for the Met said an investigation into the Electoral Commission's allegations against Vote Leave and BeLeave, submitted on July 17 2018, was handed over in October to the Crown Prosecution Service (CPS). "On Tuesday, March 3 preliminary advice was received from the CPS," said the force spokesman. "This advice has now been duly considered and no further action will be taken."
