New studies, from the Weizmann Institute of Science and the University of California, Irvine, found mice that exercised in the evening were 50% more efficient than in the morning (file image)
Taking an evening jog may be better for you than going on a morning run, two new studies find.
In research conducted on mice, scientists said that exercise performance was about 50 percent better during the evening hours.

JERUSALEM, Oct. 24 (Xinhua) – Israeli scientists revealed the mechanism of the sea cone snail’s venom, which may lead to new drugs for abnormal heart rate and high blood pressure, the Weizmann Institute of Science (WIS) reported Thursday.
The findings may also lead to the development of safe natural insecticides, because some components of this venom only kill insects, and not mammals.
The findings, published in the scientific journal PNAS, may explain some of the side effects of potassium-blocking drugs, such as heart arrythmia and hypertension drugs, and lead to the development of better ones.

Aug 01, 2015... For 10 years, Karina Yaniv has worked to find out just how much zebrafish have in common with mice—at least when it comes to their lymphatic systems, the open-ended networks of vessels best known for draining fluids from tissues and providing thoroughfares for immune cells throughout the body. Yet in doing so she ended up discovering something that had very little in common with the findings of numerous earlier studies on other animals’ lymphatic systems. Contrary to the widely held view in developmental biology, she found, lymphatics don’t always originate from veins.

In 2019, if everything goes according to plan, the much-delayed James Webb Space Telescope will finally launch into orbit. Once assembled, it will use an array of 18 hexagonal mirrors to collect and focus the light from distant galaxies. This segmented-mirror design was developed in the 1980s, and it has been so successful that it will feature in almost all the large telescopes to be built in the near future.
Oct 07, 2015... REHOVOT, ISRAEL—October 7, 2015—Most female mammals give birth and care for their offspring, while the males often breed with multiple partners and play little role in parenting once the mating is over. Yet researchers have had a hard time pinpointing where, exactly, in the brain these differences between the sexes are located and how they translate into behavior. The extent of “hardwired parental behavior” is hotly disputed.

May 15, 2014... TEDx Weizmann Institute, a conference on excellence in science and science education, will be held on May 20 at the Weizmann Institute of Science. The Institute has been working for the past 50 years to advance science education in Israel. The conference will be led by the Davidson Institute of Science Education, the educational arm of the Weizmann Institute, together with scientists and staff of the Weizmann Institute and with the support of the Trump Foundation, which promotes the advancement of science and math education.

The idea of ‘gut health’ barely existed a few years ago, but now, people in the UK spend around £750 million every year on probiotic products — ‘beneficial’ bacteria which is supposed to boost our health.
People take probiotics believing they increase levels of beneficial bacteria and will boost their immune system, digestion, mental health and more.
But last week, an expert warned that fermented foods such as sauerkraut — often consumed because of their probiotic effect — may trigger bloating, headaches and allergies.

Shortly after I had a double mastectomy, I got lymphedema in my arms. I was devastated. I knew going in what it was, and I was terrified.
Put very simply, the lymphatic system provides cells with nutrients and acts as a means of waste removal. We need it to survive. However, the same system will also carry cancer cells to other parts of the body, which is called metastasis. Cancer cells get trapped in lymph nodes and cause secondary tumors, which is why surgeons will err on the side of caution to keep the cancer from coming back. Curing cancer is their focus after all.

Ants working together to carry a large piece of food get around obstacles by switching between two types of motion: one that favors squeezing the morsel through a hole and another to seek a path around the barrier. Jonathan Ron of the Weizmann Institute, Israel, and colleagues present these findings in PLOS Computational Biology.

Some people eat as little fat as possible to lose weight and stay healthy, while others avoid carbohydrates. A vegan diet (with no animal products) and the paleo diet (with lots) both have enthusiastic devotees. One popular diet encourages intermittent fasting, another frequent small meals. Who’s right?
Perhaps they all are, according to the new field of “personalized nutrition.”
