How a pacemaker, smaller than a grain of rice, could revolutionise cardiac medicine
Researchers at Northwestern University in the US state of Illinois unveiled the device, which they say is the smallest pacemaker in the world, in a study published in the peer-reviewed medical journal Nature.
The device is still years away from being used in humans, but it could eventually be useful for infants with congenital heart defects and for adults, the researchers say.
'I think it's really exciting technology that will change how electrical stimulation is done,' says Igor Efimov, a Northwestern experimental cardiologist who co-led the study.

The device – which is just 1.8mm (1/16th of an inch) wide, 3.5mm long and 1mm thick – can be inserted with a catheter or syringe.

Gaza Humanitarian Foundation says 2 US aid workers hurt in grenade attack
The Gaza Humanitarian Foundation said on Saturday that two American aid workers had suffered non-life-threatening injuries in a grenade attack at a food distribution site in Khan Younis. Advertisement The US- and Israeli-backed GHF said in a statement that the injured Americans were receiving medical treatment and were in a stable condition. 'The attack – which preliminary information indicates was carried out by two assailants who threw two grenades at the Americans – occurred at the conclusion of an otherwise successful distribution in which thousands of Gazans safely received food,' the GHF said. GHF, which began distributing aid in Gaza in May, employs private US military contractors tasked with providing security at their sites. It was not immediately clear who was behind the attack. The Israeli military, in a later statement, accused what it called 'terrorist organisations' of sabotaging the distribution of aid in Gaza. Advertisement Gaza has seen an escalation in violence as efforts continue to reach a ceasefire agreement. Hamas on Friday reported, it had responded positively to a US-brokered deal and was prepared to enter into talks. US President Donald Trump is scheduled to meet Israeli Prime Minister Benjamin Netanyahu on Monday.

Taking care of yourself beyond health
We are constantly reminded that we need to take better care of ourselves, and we take that seriously – we try to eat less, drink more water, get better sleep and work out more. Advertisement These are important things because they help extend our physical health. But what is also important, and often overlooked, is the need for us to take care of ourselves when our health fails and we become unable to make decisions for ourselves. It is prudent – and I would say necessary – to have a system in place that we can be taken care of in the way we prefer when our health fails to the point that we cannot make decisions for ourselves. Many may think that these are unnecessary, because can we not rely on our families or our healthcare system to do that for us? The short answer is that you can, but only up to a point. Take this example. I have lost capacity, meaning my mental and cognitive abilities have declined to the point that I am considered no longer able to make decisions for myself. Advertisement I then suffer from a serious illness that requires treatment and constant care. But since I have no capacity, I cannot even draw money from my bank account to pay for my treatment and care. It may be that I have family who are able and willing to pay for that; but what if they do not have the financial means to do so, while I do?
