A team of American scientists have developed a robotic sleeve that might be able to save patients’ lives by physically keeping their heart beating in case of heart failure.
Developed by scientists from Harvard University and Boston Children’s Hospital using artificial muscles, the thin silicone-made robotic sleeve can encase a flabby diseased heart and gently squeeze it to keep it pumping.
The thin silicon sleeve alternately compresses, twists as well as relaxes in synchrony with the heart tissue beneath.

A tabular iceberg one-quarter the size of Wales may soon break off the Larsen C Ice Shelf in Antarctica as a crack in it continues to lengthen, climate scientists have warned.
Since January 1, the crack in the Larsen C Ice Shelf has extended further 10 kilometers, and scientists have warned that it would free a massive tabular berg if the rift propagates merely 20 kilometers.

The ancient Chinese practice of acupuncture may reduce colicky crying among babies when other treatments do not help, a new study suggested.
Crying is normal for babies but those who cry more than three hours a day and continue to do so for more than three days a week might be give a sign that a physician’s intervention is required. Excessive crying is also called infantile colic.

British climate scientists have urged Prime Minister Theresa May to press U.S. President-elect Donald Trump to acknowledge risks being posed by climate change and support international efforts to tackle global warming.
In a letter written to Mrs. May on Monday, a group of 100 climate scientists said there were real threats to Britain’s interests from Mr. Trump’s victory in November.

Benefits of grandmothering may have played a major role in the success of older female orcas (killer whales) but the costs of being outcompeted by their daughters apparently play a role in the emergence of their menopause, a new study suggested.
According to the study, published in the journal Current Biology, younger females are more likely to mate and reproduce than their older counterparts. They found that this trend puts off mother orcas from reproduction, which in turn make them more focused on raising their younger members of their families instead.

Marine biologists had been of the view that only two types of sea dragons existed, the leafy and weedy, until they discovered a third type in 2015. The third type of the enchanting fish, the ruby sea dragon, was first found among museum specimens; and now biologists have spotted a ruby sea dragon swimming in the wild too.
Spotted for the first time in the wild, the ruby sea dragon has deep red color and appears like a stretched-out sea horse and hump like a camel. It can curl its tail.

More than two dozen states in the U.S. have legalized marijuana and millions of people across the nation use the drug each month, but the precise health effects of the drug on those who use it remain a mystery.
Experts say they have only a hazy idea of the drug’s myriad health effects, and argue that federal laws are to be blamed for the issue. Some experts say that the federal government is erecting major barriers to research that would have provided answers to solve the mystery.

Smoking costs the global economy more than $1 trillion annually and the habit will be claiming as many as 8 million lives each year by 2030, according to a new report by the World Health Organization (WHO) and the U.S. National Cancer Institute (NCI).
The newly published report stressed that the cost of smoking far outweighs taxes generated through tobacco sales, which have been estimated at around $269 billion for the year of 2013-2014.

An unprecedented detection of a repeating “Fast Radio Burst (FRB)” has allowed astronomers to identify its origin, prompting scientists to reconsider what they believed they knew about FRBs.
FRBs are tremendously powerful flashes of cosmic light, which can be detected from billions of light-years away. In spite of the ferocity of the bursts, these radio emissions are rarely detected because of they are extremely short-lived.
As FRBs last for just a fraction of a second, they are hard to capture, and their origin is even harder to pinpoint.
