Two more animal care experts from Vancouver Aquarium’s marine science centre went to California on Monday so that they could help deal with the issue of sea lion pups being washed ashore.

Dr. Martin Haulena, head veterinarian at the Vancouver Aquarium, said they are not sure about the reason behind such a large number of sick and starving pups being stranded on beaches.

But they theorized that warm sea water could be a reason to this because warmer water might be reducing the amount of prey the pups normally feed on.

“Because of warmer water the usual prey species aren’t as abundant as they should be, which forces mothers to leave their pups longer while they search for food and may result in weaning of underweight pups earlier than normal”, Haulena said.

Scientists from the University of California at Irvine have resolved the mystery of color-shifting squid. Inspired by the squid’s ability to become invisible, the scientists have created ‘invisibility stickers’ by using a protein found in squid skin. This might make soldiers invisible to thermal sensing and night vision devices like infrared camera.

Alon Gorodetsky from University of California at Irvine said that soldiers wear uniforms with the familiar green and brown camouflage patterns, which helps them to blend into vegetation during the day. However, they are susceptible to infrared detection at night and under low light.

SpaceX has launched its first deep space mission last month, when the Falcon 9 rocket carried the Deep Space Climate Observatory (DSCOVR) satellite into orbit.

During the mission, remarkable images were taken and some were made public, but some commentators noted a possible downside to the new era of privately-funded space exploration.

The photographs produced by every NASA mission can be put in the public domain but the same can’t be done in the case of SpaceX photos.

Usually, NASA photos are put into public domain by default, because the works that are created by the US federal government or its employees can't be copyrighted.

The US food and Drug Administration (FDA) has announced that Aurora Products is recalling its products distributed through retail stores in the U. S., Canada and in Bermuda.

The company based in Orange, Conn is recalling products from sold at Giant food stores and Stop & Shop stores due to possible contamination with Salmonella.

The potential Salmonella contamination was discovered during routine testing by an outside company. The company contacted the FDA after finding the presence of Salmonella in a container of natural walnut products.

Salmonella contamination can lead to serious and fatal infections. Elderly people, children younger than age 5, and immune-compromised, i. e. people with compromised immune systems are at greatest risk of serious infection.

The US Preventive Services Task Force (USPSTF) said that it cannot say with 100% assurance whether or not blood test should be done for thyroid dysfunction in adults without symptoms

The US government-backed panel said that more clinical trials and scientific evidence is needed to come up with a better solution. The USPSTF said, "The Task Force concludes that current evidence is insufficient to assess the balance of benefits and harms of screening for thyroid dysfunction in nonpregnant, asymptomatic adults".

The task force has warned about the potential risks involving screening of asymptomatic individuals. If by chance, false positive results report comes then it could result into potential physical harms from overtreatment.

Kara Tippetts, 38, wife of a pastor and a mother of four who was suffering from stage-four breast cancer, died on Sunday, March 22.

In last years of her life, she accepted her sufferings in a quietly powerful way, a cultural force for another way of choosing death with dignity.

Tippetts even wrote a book, 'The Hardest Peace: Expecting Grace in the Midst of Life's Hard', and she also had a blog, 'Mundane Faithfulness', that was full of praise for God and images of a woman well-loved by friends and family.

Her posts on her blog were majorly filled with Christian vision that physician-assisted dying is not an act of loving life, but rather a betrayal of love, God and faith.
