Robotic jellyfish takes to the water without a tether

Although jellyfish may not be the fastest animals in the ocean, they do swim in an energy-efficient manner – a manner that underwater robots might do well to copy. With that in mind, Chinese scientists have created a robotic jellyfish, that m… Continue reading Robotic jellyfish takes to the water without a tether

Dual Beam bike light illuminates the rider and the road

If you’re driving at night, which are you more likely to notice: a single spot of light, or an entire illuminated human torso? Colorado-based cyclists Alex Mulvaney and Kathy Vega are betting on the second of the two, which is why they invent… Continue reading Dual Beam bike light illuminates the rider and the road

Newly-discovered prehistoric marine predator was a big deal in its time

Half a billion years ago, in the Cambrian Period, most animals were smaller than a person’s little finger. That makes the recent discovery of a marine predator from that time all the more exciting, as the sucker grew to up one foot (30 cm) lo… Continue reading Newly-discovered prehistoric marine predator was a big deal in its time

Venomous snake fangs inspire new microneedle drug-delivery system

For several years now, we’ve been hearing about “microneedle patches” that deliver medication less painfully and more safely than hypodermic needles. A new take on the technology may allow them to work even better, by copying the structure of… Continue reading Venomous snake fangs inspire new microneedle drug-delivery system

Medicinal herb receives a diabetes-fighting boost

Commonly known as Paneer dodi, the herb Withania coagulans has been used in traditional Indian medicine for many years now – among other things, it is claimed to help control diabetes. A new study shows that it indeed may do so, particularly … Continue reading Medicinal herb receives a diabetes-fighting boost

Skin-worn stretchable device wirelessly transmits health data

When it comes to the continuous monitoring of people’s vital signs, the rigid electrodes that are typically adhered to the skin can be uncomfortable, awkward, and a cause of skin irritation. That’s where a new soft, flexible, wireless monitor… Continue reading Skin-worn stretchable device wirelessly transmits health data

Human torso simulator is set to test back braces

If you were designing a new back brace, trying it out on people could be kind of risky – what if it was flawed, and ended up hurting the test subjects? It was with this in mind that scientists at Britain’s University of Lancaster have created… Continue reading Human torso simulator is set to test back braces

Wearable measures muscle activity to guard against injuries

Tennis elbow, carpal tunnel syndrome, and “mouse arm” all have two things in common: they’re the result of muscle strain, and they’re the subject of a new wearable. Known as MLI Elbow, the Danish device is aimed at alerting users to actions t… Continue reading Wearable measures muscle activity to guard against injuries

Computer system learns to spot fake smiles

In the near future, it may be a lot more difficult to make computers believe that you’re happy with something when you’re actually not. That’s because scientists at Britain’s University of Bradford have developed software that can reportedly … Continue reading Computer system learns to spot fake smiles
