Starships are meant to fly: SpaceX’s rocket finally launches after setbacks

Test flight comes after explosive failures raised doubts over founder Elon Musk’s goals to reach Mars and moon

Third time was the charm on Tuesday for the launch of SpaceX’s Starship megarocket after the launch had been scrubbed two times in as many days. The success of this 10th flight proved the spacecraft had overcome its past failures key to the Mars rocket’s reusable design.

The stainless steel behemoth, 403ft (123 meters) tall, lifted off from the company’s Starbase in southern Texas at 6.30pm local time (2330 GMT), to loud cheers from engineering teams, a webcast showed. This mission was to be a test of the ship’s new heat shield tiles and satellite deployment abilities, among hundreds of other upgrades from past iterations.

Stigma around mifepristone is stopping studies, experts in reproductive health claim in Lancet opinion piece

A drug used in medical abortions could help prevent women at high risk of breast cancer from developing the disease, according to an international group of doctors and scientists.

However, “stigma” around mifepristone is stopping pharmaceutical companies from investigating its potential as a new treatment doctors could offer to reduce the risk of breast cancer, they say.

MSF charity calls situation ‘beyond urgent’ as thousands seeking refuge from war rely on contaminated water

The “worst cholera outbreak in years” has killed at least 40 people in the last week in Sudan, according to the medical charity Médecins Sans Frontières.

Overwhelmed medical centres are resorting to treating patients on mattresses on the floor, MSF said, as the country’s two-year civil war aids the spread of the disease.

‘Social apnoea’: sleep disorder could worsen at weekends, research suggests

Posted on by

Lifestyle factors such as drinking and smoking could contribute to increased severity of obstructive sleep apnoea

Letting your hair down at the weekend might be a well-known recipe for a hangover, but researchers say it might also increase the severity of a common sleep disorder.

Obstructive sleep apnoea (OSA) involves complete pauses in breathing or partial reductions in airflow that arise because muscles in the back of the throat relax, causing the airways to narrow or close. It is more common in groups such as older people and people who are overweight or obese.

Organisers say move will damage nation’s scientific standing as government refuses to comment on why group of scientists were refused entry

Organisers of an international research conference have criticised a last-minute Australian government decision to deny visas to eight invited researchers, mostly from Asia and Africa.

Prof Justin Welbergen, chair of the 20th International Bat Research Conference in Cairns, said the decision to deny the researchers entry without option to appeal had disrupted the event, which is a key forum for global collaboration on bat research and conservation.

Administration’s move to cut thousands of agency jobs will be devastating for US public health, union warns

The Environmental Protection Agency (EPA) said on Friday it is eliminating its research and development arm and reducing agency staff by thousands of employees. One union leader said the moves “will devastate public health in our country”.

The agency’s office of research and development (ORD) has long provided the scientific underpinnings for the EPA’s mission to protect the environment and human health. The EPA said in May it would shift its scientific expertise and research efforts to program offices that focus on major issues such as air and water.

Sudan’s children face growing threat of deadly infectious diseases as vaccination rates halve

The country, beset by war, has the world’s lowest rates of vaccination, says the World Health Organization, as global immunisation drive also stalls

Children in Sudan, caught up in what aid organisations have called the world’s largest humanitarian crisis and threatened by rising levels of violence, are increasingly vulnerable to deadly infectious diseases as vaccinations in the country plummet.

In 2022, more than 90% of young children in Sudan received their routine vaccinations. But that figure has nearly halved to 48%, the lowest in the world, according to the World Health Organization.

Some gut microbes can absorb and help expel ‘forever chemicals’ from the body, research shows

Previously, the only way to reduce levels of Pfas was by bloodletting or a drug with unpleasant side effects

Certain kinds of gut microbes absorb toxic Pfas “forever chemicals” and help expel them from the body via feces, new first-of-its-kind University of Cambridge research shows.

The findings are welcome news as the only options that exist for reducing the level of dangerous Pfas compounds from the body are bloodletting and a cholesterol drug that induces unpleasant side effects.

European Commission unveils strategy for storing food, medicine, generators and raw materials

The EU should develop stockpiles of food, medicine, generators and raw materials to be better prepared for a military invasion, pandemic or natural disaster, the European Commission has said.

Outlining its first-ever strategy on stockpiling, the EU executive said on Wednesday member states should also consider emergency supplies of water purification products, equipment to repair undersea cables, drones and mobile bridges for use in conflicts.

A man whose bones were shaped by a lifetime of hard labour more than 4,500 years ago has become the first ancient Egyptian to have his entire genetic code read and analysed by scientists.

The skeleton of the man, who lived at the dawn of the Age of the Pyramids, was recovered in 1902 from a sealed pottery vessel in a rock-cut tomb in Nuwayrat, 165 miles south of Cairo, and has been held in a museum since.

News comes as research finds record lows of Antarctic sea ice had seen more icebergs splintering off ice shelves

Scientists analysing the cascading impacts of record low levels of Antarctic sea ice fear a loss of critical US government satellite data will make it harder to track the rapid changes taking place at both poles.

Researchers around the globe were told last week the US Department of Defence will stop processing and providing the data, used in studies on the state of Arctic and Antarctic sea ice, at the end of this month.
