Scientists from the University of Chicago have found remnants of seawater dating back to the Ice Age that existed more than 20,000 years ago. The untouched water was discovered inside a rock formations in the Indian Ocean. Researchers had to earlier rely on indirect clues, like fossil corals and chemical signatures on the seafloor to reconstruct Ice Age seawater but thanks to this discovery they now have an actual piece of the 20,000-year-old ocean. Properties of the seawater suggest that salinity in the Southern Ocean may have had more impact on driving ocean circulation than it does today.

The issue of tobacco smoking and risk for acute respiratory infection has become a talking point amid the Covid-19 pandemic. According to a paper published in The Lancet journal, robust evidence suggests that several mechanisms may increase the risk of respiratory tract infections in smokers.&nbsp;Smoking impairs the immune system and the ability to contain infection. The risk of contracting pneumonia&nbsp;is about 3&ndash;5 times higher in smokers and they&nbsp;are also 5-times more likely to contract&nbsp;influenza, states the paper. There's not enough evidence to support that tobacco smoking increases the risk of being infected by Covid-19. However, available studies indicate that&nbsp;current smokers have increased gene expression of ACE2 - the main receptor used by the Covid-19 virus to gain entry to host cells and cause active infection.&nbsp;The challenge for Covid-19 studies is to have large enough sample sizes with all variables that might be associated with tobacco smoking and health.&nbsp;

Jack Rico is not your ordinary 13-year old. The brilliant teenager just graduated from the Fullerton College in California with four associate's degrees and he did it in just two years! In the school's&nbsp;107-year-old history, Rico is the youngest to achieve the feat. He majored in history, human expression, social behavior and social science and he maintained a&nbsp;4.0 GPA&nbsp;in all of them. He will now be studying history at the University of Nevada in&nbsp;Las Vegas.

UK Scientist Dr Alan Jamieson&nbsp;has captured the world's deepest octopus on camera. Discovered&nbsp;7,000 metres down in the Java Trench, on the floor of the Indian ocean, it is believed to be a "Dumbo" octopus species. Dr Jamieson's equipment called 'lander' filmed two octopuses - one on a drop to 5,760 metres and a second around 6,957 metres. The&nbsp;previous deepest reliable sighting was at 5,145 metres down. The discovery shows that octopuses can find suitable habitat across at least 99% of the global seafloor.&nbsp;

The next time&nbsp;you find a robot serving you at a restaurant, don't be surprised! Netherlands'&nbsp;Royal Palace is trialling two robotic waiters, ahead of its opening next week.

In an unfortunate incident,&nbsp;a 40-foot long fin whale, believed to be a juvenile, washed up dead on a beach in southeast England on Friday. Authorities have urged locals to keep away from the beach to avoid the risk of infection.&nbsp;The British Divers Marine Life Rescue charity said that the whale appeared small for the species. The endangered fin whale is the second-largest mammal in the world after the blue whale.

According to a new study published in the journal Science, the climate crisis and the mass felling of trees has made forests across the world, 'shorter and younger' and the trend is expected to continue. This comes with worrying consequences for the ability of forests to mitigate risks of climate change and store carbon. It could also impact wildlife that are dependent on these forests for their survival. According to researchers led by the U.S. Department of Energy's Pacific Northwest National Laboratory, the death rate of trees has increased due high temperature, drought, pests and a number of diseases.&nbsp;

The Indian Institute of Technology in Roorkee will be conducting research on identifying antivirals&nbsp;to treat the Covid-19 virus.&nbsp;The study is funded under the intensification of Research in High&nbsp;Priority areas under the Department of Science and Technology.&nbsp;Researchers will work on identifying small molecule inhibitors to target key enzymes that replicate the virus in the body.&nbsp;This will help expedite the process of identification of drugs that can be used to treat Covid-19.&nbsp;An IIT Roorkee professor Dr.&nbsp;Kamal Jain also&nbsp;recently created a new surveillance system for tracking suspected Covid-19 patients.&nbsp;

A team from&nbsp;IIT&nbsp;Madras has helped triple the&nbsp;Irrawaddy dolphin population at the Chilika&nbsp;Lake,&nbsp;Asia's largest brackish water body, in Odisha. The researchers&nbsp;conducted geotechnical, hydraulic and satellite imagery studies and developed a dredging methodology for the project. The project will also be of massive help for 200,000 fishermen living in 132 nearby villages as it resulted in a seven-fold increase of fish. 'The lake was in a degraded condition and included in the threatened list by Ramsar Convention in 1993,' IIT&nbsp;Madras professor said.
