The spring asterism known as the Great Diamond is a pattern of four stars from different constellationsThis week, track down the asterism known as the Great Diamond. Asterisms are patterns of stars that exist alongside the officially defined constellations. In this case, the Great Diamond consists of four stars. Cor Caroli in Canes Venatici, the hunting dogs; Denebola in Leo, the lion; Spica in Virgo, the virgin; Arcturus in Boötes, the herdsman. Continue reading...

Many people suffer effects of coronavirus for months while reporting a wider range of symptoms than NHS guidelines state

Erotic transference can be completely devastating, and handling it requires extreme careThere’s nothing quite like it. You sit together in hushed intimacy, just the two of you, finally revealing lifelong secrets. The atmosphere is exquisitely calm, the tranquillity shot through with alertness as the world shifts, brilliantly refigured, and relief floods in. You have the certainty that you are protected and profoundly understood by someone who is on your side. As Freud wrote, “Analysis is, in essence, a cure through love.”From the very act of revelation, a feeling of affinity can grow. In such safety and solace, with all the exclusive focus you could ever wish for, you start wondering about this person who sits opposite you – the therapist. This expert trained to understand the human heart. Who is this enigma, who gives clues to their personality only through their clothes, voice, décor? Continue reading...

Sage member also says Covid-19 ‘definitely not over’ and urges caution in easing lockdown

The personal items that Neil, Buzz and others carried with them – and left up thereBeyond the usual travel essentials, any keepsakes, charms and totems we take with us on our journeys say a lot about our inner worlds. The faithful may carry a crucifix, a rosary or the Qur’an; superstitious sailors still carry amulets to ensure a “smooth voyage”; soldiers treasure pictures of their sweethearts. Before photography they would carry a lock of their loved one’s hair.When the two crew members of the SpaceX Falcon 9 set off on their historic space journey last week, their totem was a toy dinosaur, taken on the behest of their sons. During the Apollo missions to the moon, the personal items astronauts could take were restricted: each had just a small “personal allowance pouch”. Continue reading...

Scientists are racing to work out why some populations have fared better than others during the pandemic

Medical chiefs call for a public health campaign as faith in government strategy slumps

The hunt for a coronavirus vaccine has led to refusals to share research“It’s tragic that we won’t have a vaccine ready for this epidemic,” Peter Hotez told a US congressional committee in March. Tragic, because we could possibly already have had one.Hotez is director of the Center for Vaccine Development at the Texas Children’s Hospital. In 2016, he and his team developed a vaccine for Sars-1, the virus that first appeared in China in 2003. Today’s coronavirus, Sars-Cov-2, Hotez observes, is “about 80% similar [to Sars-1]”. But by the time he developed the vaccine, Sars was no longer a public health issue and nobody was interested in funding the work. Hotez is now working to “repurpose our Sars-1 vaccine to fight Sars-2”. But had “investments been made previously, we potentially could have [had] a vaccine ready to go now”. Continue reading...

Doctors say they are making progress in understanding the disease, but warn against hoping for an early vaccine

With a mission to Mars on the horizon and astronauts spending longer than ever in orbit, scientists are looking for ways to grow vegetables in space...In The Martian, the 2015 film directed by Ridley Scott, astronaut Mark Watney (Matt Damon) is accidentally abandoned alone on Mars by his crewmates after an emergency evacuation, without enough food to survive. Mars is a tricky prospect for even the most red- fingered gardener: there’s almost no air, the “soil” has few nutrients and lots of heavy metals, and the temperature is typically around -60C. “I’m going to have to science the shit out of this,” Watney, a botanist, declares. He decides to grow potatoes, jerry-rigging a climate-controlled dome, burning hydrazine to make water and creating a growth medium from Mars dust supplemented by his crewmates’ faeces.In Star Trek they just replicate food out of pure energy Continue reading...

The US stimulus programme looks to have been a success: one that has political as well as economic consequencesThe political obituaries of Donald Trump were all prepared. At the end of a week that has seen American cities convulsed by protests over the killing of George Floyd, the president would be faced with an increase in unemployment worse than anything seen in the Great Depression.Well, it didn’t turn out like that. The US economy actually created 2.5 million jobs in May and the unemployment rate went down rather than up. The consensus among analysts was that it would shed 7.5 million jobs, a colossally wrong call. And a deeply significant one. Continue reading...

I’ve had a fever, a cough and breathlessness since February, and been in and out of hospital. If it isn’t coronavirus, what is it? By Simon HattenstoneI’m lying in bed, shivering like crazy. My partner, Diane, is asleep, and I burrow deep into her back. I’m sweating like crazy, too. I’m desperate for the loo, and I run there in my shivery sweats and sweaty shivers. It’s only five minutes since I last went. When I sleep, the same obsessive moment plays again and again. It’s to do with numbers. I need to get past number nine, but I can’t. The dream lasts for hours. Finally, I force myself awake. Ten minutes have passed. Continue reading...

‘Third of Americans’ misused disinfectants to try to prevent infection; IMF agrees $5.2bn package for Egypt

Retractions by two of the world’s leading journals could do lasting harm in an environment where many already distrust scientistsPublic trust in science may have been shaken by the publication of academic papers based on false data in leading medical journals, according to world-renowned infectious disease doctors and former advisers to the World Health Organization.The director of Australia’s Peter Doherty Institute for Infection and Immunity, Professor Sharon Lewin, said she and her colleagues were “gobsmacked” by the saga and said it should be “a wake-up call” in a global rush to publish studies about Covid-19.

Yes, more people of black, Latin and south Asian origin are dying, but there is no genetic ‘susceptibility’ behind itFrom the start of the coronavirus pandemic, there has been an attempt to use science to explain the disproportionate impact of Covid-19 on different groups through the prism of race. Data from the UK and the US suggests that people categorised as black, Hispanic (Latino) and south Asian are more likely to die from the disease.The way this issue is often discussed, but also the response of some scientists, would suggest that there might be some biological reason for the higher death rates based on genetic differences between these groups and their white counterparts. But the reality is there is no evidence that the genes used to divide people into races are linked to how our immune system responds to viral infections. Continue reading...

Questions raised over study claiming drug linked to higher rate of mortality and heart problems in Covid-19 patients

Creatures’ attempts are in vain, and as they are unable to burrow through the fish’s ribcage, the eels become trapped in the gut of their captorIt’s no secret that nature can be brutal and violent, but a new Queensland Museum report on the death of some snake eels reads more like the plot of a horror movie than a scientific paper.Snake eels are a family of eel species that live most of their lives burrowed in the soft sand on the floor of the ocean.

Rather than pitting old people against the young, now is the time to unite against a system that only benefits those who are wealthy

Langstone, Hampshire: This industrious little insect collects mud to partition off cells in the garden box I put up for herA few weeks ago, my neighbours had cavity wall insulation installed and the resulting drill holes in their gable-end wall were soon being prospected by red mason bees (Osmia bicornis).People often assume that the common name of these gingery, spring-flying solitary bees refers to a tendency to nest in crumbling mortar, but it’s more likely to derive from their habit of using mud as a mortar-like material to line and partition their brood cells. While females do make use of crevices between old brickwork, they also nest in hollow plant stems and beetle boreholes in dead wood, and will readily occupy manmade bee hotels. Continue reading...

Surgisphere, whose employees appear to include a sci-fi writer and adult content model, provided database behind Lancet and New England Journal of Medicine hydroxychloroquine studiesThe World Health Organization and a number of national governments have changed their Covid-19 policies and treatments on the basis of flawed data from a little-known US healthcare analytics company, also calling into question the integrity of key studies published in some of the world’s most prestigious medical journals.A Guardian investigation can reveal the US-based company Surgisphere, whose handful of employees appear to include a science fiction writer and an adult-content model, has provided data for multiple studies on Covid-19 co-authored by its chief executive, but has so far failed to adequately explain its data or methodology.

It is hard for the public to trust a government that prioritises political messaging ahead of deliveryThere is no such thing as a total truce in Westminster, and a partial one rarely lasts long. The period when Labour felt obliged by a sense of duty in a national emergency to provide “constructive” opposition to the government is over. In parliament on Wednesday, Sir Keir Starmer accused Boris Johnson of failing to get to grips with the situation and the prime minister responded with affected resentment at the lack of “cooperation” from his counterpart across the dispatch box.But it was Mr Johnson’s decision to support Dominic Cummings over alleged lockdown breaches that incinerated any prospect of political consensus on coronavirus policy. By failing to chastise his maverick aide, the Tory leader committed two grave mistakes. First, he effectively diluted the mandatory element of the regulations, creating an unwritten “Cummings clause” for anyone minded to interpret the rules leniently for themselves. Second, he politicised the whole lockdown issue by making it clear that science and evidence are subordinate to the whim of a single Downing Street adviser. Continue reading...
