Experts warn of long-term health implications amid concerns over advice from social media ‘evangelists’

• ‘Frightening’ how easily women able to get hold of testosterone, say doctors

The prescribing of testosterone for middle-aged women is “out of control” and may have long-term implications for their health, experts have warned.

They are concerned that “testosterone evangelists” on social media – including some celebrities and GPs – are giving women the impression that the hormone will reduce fatigue and improve their energy levels, as well as protecting their heart, brain, muscles and bones. But experts say the evidence only supports its use in postmenopausal women with low libido, when psychosocial causes have been ruled out.

Schools and health services forced to offer crisis help in the form of food, clothing, money and advice

Britain’s schools and primary health services are “staggering” under the pressure of demand caused by an epidemic of extreme poverty, as desperate families unable to afford food, clothing or heating increasingly turn to them for crisis help.

Teachers and GPs in England, Scotland and Wales are informally acting as emergency food providers, welfare advisers, housing officers and social workers alongside their day jobs, as they devote more and more time and resources to support struggling parents and children, new research has found.

Primary school staff estimated 48% of their pupils, and primary care staff 57% of their patients, had experienced hardship at some point since the start of the school year or over the past 12 months.

A third of schools, and nearly half of GP surgeries, had set up food banks to provide emergency food supplies to hungry pupils and families. Staff in schools in deprived areas estimated 44% of pupils had come to school hungry over the past year.

Nearly a quarter of NHS primary care staff and 40% of teachers said they had dipped into their own pockets to help pupils and patients. In one case, a nurse gave new underpants, still in their packet and intended for her husband, to a desperate patient.

Dr Joseph Cotter takes some unusual pieces of luggage on his trips on the London underground. They include a stainless steel vacuum chamber, a few billion atoms of rubidium and an array of lasers that are used to cool his equipment to a temperature just above absolute zero.

While not the average kit you would expect to find being dragged into carriages on the District Line, this is the gear that Cotter – who works at Imperial College London’s Centre for Cold Matter – uses on his underground travels.

This is a dangerous vulnerability:

An assessment from security firm BitSight found six vulnerabilities in the Micodus MV720 , a GPS tracker that sells for about $20 and is widely available. The researchers who performed the assessment believe the same critical vulnerabilities are present in other Micodus tracker models. The China-based manufacturer says 1.5 million of its tracking devices are deployed across 420,000 customers. BitSight found the device in use in 169 countries, with customers including governments, militaries, law enforcement agencies, and aerospace, shipping, and manufacturing companies.

BitSight discovered what it said were six “severe” vulnerabilities in the device that allow for a host of possible attacks. One flaw is the use of unencrypted HTTP communications that makes it possible for remote hackers to conduct adversary-in-the-middle attacks that intercept or change requests sent between the mobile application and supporting servers. Other vulnerabilities include a flawed authentication mechanism in the mobile app that can allow attackers to access the hardcoded key for locking down the trackers and the ability to use a custom IP address that makes it possible for hackers to monitor and control all communications to and from the device.

The security firm said it first contacted Micodus in September to notify company officials of the vulnerabilities. BitSight and CISA finally went public with the findings on Tuesday after trying for months to privately engage with the manufacturer. As of the time of writing, all of the vulnerabilities remain unpatched and unmitigated.

These are computers and computer vulnerabilities, but because the computers are attached to cars, the vulnerabilities become potentially life-threatening. CISA writes :

These vulnerabilities could impact access to a vehicle fuel supply, vehicle control, or allow locational surveillance of vehicles in which the device is installed.

I wouldn’t have buried “vehicle control” in the middle of that sentence.
